Robert McQueen: Flathub in 2023

It s been quite a few months since the most recent updates about Flathub last year. We ve been busy behind the scenes, so I d like to share what we ve been up to at Flathub and why and what s coming up from us this year. I want to focus on: Today Flathub is going strong: we offer 2,000 apps from over 1,500 collaborators on GitHub. We re averaging 700,000 app downloads a day, with 898 million HTTP requests totalling 88.3 TB served by our CDN each day (thank you Fastly!). Flatpak has, in my opinion, solved the largest technical issue which has held back the mainstream growth and acceptance of Linux on the desktop (or other personal computing devices) for the past 25 years: namely, the difficulty for app developers to publish their work in a way that makes it easy for people to discover, download (or sideload, for people in challenging connectivity environments), install and use. Flathub builds on that to help users discover the work of app developers and helps that work reach users in a timely manner. Initial results of this disintermediation are promising: even with its modest size so far, Flathub has hundreds of apps that I have never, ever heard of before and that s even considering I ve been working in the Linux desktop space for nearly 20 years and spent many of those staring at the contents of dselect (showing my age a little) or GNOME Software, attending conferences, and reading blog posts, news articles, and forums. I am also heartened to see that many of our OS distributor partners have recognised that this model is hugely complementary and additive to the indispensable work they are doing to bring the Linux desktop to end users, and that having more apps available to your users is a value-add allowing you to focus on your core offering and not a zero-sum game that should motivate infighting. Ongoing Progress Getting Flathub into its current state has been a long ongoing process. Here s what we ve been up to behind the scenes: Development Last year, we concluded our first engagement with Codethink to build features into the Flathub web app to move from a build service to an app store. That includes accounts for users and developers, payment processing via Stripe, and the ability for developers to manage upload tokens for the apps they control. In parallel, James Westman has been working on app verification and the corresponding features in flat-manager to ensure app metadata accurately reflects verification and pricing, and to provide authentication for paying users for app downloads when the developer enables it. Only verified developers will be able to make direct uploads or access payment settings for their apps. Legal So far, the GNOME Foundation has acted as an incubator and legal host for Flathub even though it s not purely a GNOME product or initiative. Distributing software to end users along with processing and forwarding payments and donations also has a different legal profile in terms of risk exposure and nonprofit compliance than the current activities of the GNOME Foundation. Consequently, we plan to establish an independent legal entity to own and operate Flathub which reduces risk for the GNOME Foundation, better reflects the independent and cross-desktop interests of Flathub, and provides flexibility in the future should we need to change the structure. We re currently in the process of reviewing legal advice to ensure we have the right structure in place before moving forward. Governance As Flathub is something we want to set outside of the existing Linux desktop and distribution space and ensure we represent and serve the widest community of Linux users and developers we ve been working on a governance model that ensures that there is transparency and trust in who is making decisions, and why. We have set up a working group with myself and Mart n Abente Lahaye from GNOME, Aleix Pol Gonzalez, Neofytos Kolokotronis, and Timoth e Ravier from KDE, and Jorge Castro flying the flag for the Flathub community. Thanks also to Neil McGovern and Nick Richards who were also more involved in the process earlier on. We don t want to get held up here creating something complex with memberships and elections, so at first we re going to come up with a simple/balanced way to appoint people into a board that makes key decisions about Flathub and iterate from there. Funding We have received one grant for 2023 of $100K from Endless Network which will go towards the infrastructure, legal, and operations costs of running Flathub and setting up the structure described above. (Full disclosure: Endless Network is the umbrella organisation which also funds my employer, Endless OS Foundation.) I am hoping to grow the available funding to $250K for this year in order to cover the next round of development on the software, prepare for higher operations costs (e.g., accounting gets more complex), and bring in a second full-time staff member in addition to Bart omiej Piotrowski to handle enquiries, reviews, documentation, and partner outreach. We re currently in discussions with NLnet about funding further software development, but have been unfortunately turned down for a grant from the Plaintext Group for this year; this Schmidt Futures project around OSS sustainability is not currently issuing grants in 2023. However, we continue to work on other funding opportunities. Remaining Barriers My personal hypothesis is that our largest remaining barrier to Linux desktop scale and impact is economic. On competing platforms mobile or desktop a developer can offer their work for sale via an app store or direct download with payment or subscription within hours of making a release. While we have taken the time to first download time down from months to days with Flathub, as a community we continue to have a challenging relationship with money. Some creators are lucky enough to have a full-time job within the FLOSS space, while a few superstar developers are able to nurture some level of financial support by investing time in building a following through streaming, Patreon, Kickstarter, or similar. However, a large proportion of us have to make do with the main payback from our labours being a stream of bug reports on GitHub interspersed with occasional conciliatory beers at FOSDEM (other beverages and events are available). The first and most obvious consequence is that if there is no financial payback for participating in developing apps for the free and open source desktop, we will lose many people in the process despite the amazing achievements of those who have brought us to where we are today. As a result, we ll have far fewer developers and apps. If we can t offer access to a growing base of users or the opportunity to offer something of monetary value to them, the reward in terms of adoption and possible payment will be very small. Developers would be forgiven for taking their time and attention elsewhere. With fewer apps, our platform has less to entice and retain prospective users. The second consequence is that this also represents a significant hurdle for diverse and inclusive participation. We essentially require that somebody is in a position of privilege and comfort that they have internet, power, time, and income not to mention childcare, etc. to spare so that they can take part. If that s not the case for somebody, we are leaving them shut out from our community before they even have a chance to start. My belief is that free and open source software represents a better way for people to access computing, and there are billions of people in the world we should hope to reach with our work. But if the mechanism for participation ensures their voices and needs are never represented in our community of creators, we are significantly less likely to understand and meet those needs. While these are my thoughts, you ll notice a strong theme to this year will be leading a consultation process to ensure that we are including, understanding and reflecting the needs of our different communities app creators, OS distributors and Linux users as I don t believe that our initiative will be successful without ensuring mutual benefit and shared success. Ultimately, no matter how beautiful, performant, or featureful the latest versions of the Plasma or GNOME desktops are, or how slick the newly rewritten installer is from your favourite distribution, all of the projects making up the Linux desktop ecosystem are subdividing between ourselves an absolutely tiny market share of the global market of personal computers. To make a bigger mark on the world, as a community, we need to get out more. What s Next? After identifying our major barriers to overcome, we ve planned a number of focused initiatives and restructuring this year: Phased Deployment We re working on deploying the work we have been doing over the past year, starting first with launching the new Flathub web experience as well as the rebrand that Jakub has been talking about on his blog. This also will finally launch the verification features so we can distinguish those apps which are uploaded by their developers. In parallel, we ll also be able to turn on the Flatpak repo subsets that enable users to select only verified and/or FLOSS apps in the Flatpak CLI or their desktop s app center UI. Consultation We would like to make sure that the voices of app creators, OS distributors, and Linux users are reflected in our plans for 2023 and beyond. We will be launching this in the form of Flathub Focus Groups at the Linux App Summit in Brno in May 2023, followed up with surveys and other opportunities for online participation. We see our role as interconnecting communities and want to be sure that we remain transparent and accountable to those we are seeking to empower with our work. Whilst we are being bold and ambitious with what we are trying to create for the Linux desktop community, we also want to make sure we provide the right forums to listen to the FLOSS community and prioritise our work accordingly. Advisory Board As we build the Flathub organisation up in 2023, we re also planning to expand its governance by creating an Advisory Board. We will establish an ongoing forum with different stakeholders around Flathub: OS vendors, hardware integrators, app developers and user representatives to help us create the Flathub that supports and promotes our mutually shared interests in a strong and healthy Linux desktop community. Direct Uploads Direct app uploads are close to ready, and they enable exciting stuff like allowing Electron apps to be built outside of flatpak-builder, or driving automatic Flathub uploads from GitHub actions or GitLab CI flows; however, we need to think a little about how we encourage these to be used. Even with its frustrations, our current Buildbot ensures that the build logs and source versions of each app on Flathub are captured, and that the apps are built on all supported architectures. (Is 2023 when we add RISC-V? Reach out if you d like to help!). If we hand upload tokens out to any developer, even if the majority of apps are open source, we will go from this relatively structured situation to something a lot more unstructured and we fear many apps will be available on only 64-bit Intel/AMD machines. My sketch here is that we need to establish some best practices around how to integrate Flathub uploads into popular CI systems, encouraging best practices so that we promote the properties of transparency and reproducibility that we don t want to lose. If anyone is a CI wizard and would like to work with us as a thought partner about how we can achieve this make it more flexible where and how build tasks can be hosted, but not lose these cross-platform and inspectability properties we d love to hear from you. Donations and Payments Once the work around legal and governance reaches a decent point, we will be in the position to move ahead with our Stripe setup and switch on the third big new feature in the Flathub web app. At present, we have already implemented support for one-off payments either as donations or a required purchase. We would like to go further than that, in line with what we were describing earlier about helping developers sustainably work on apps for our ecosystem: we would also like to enable developers to offer subscriptions. This will allow us to create a relationship between users and creators that funds ongoing work rather than what we already have. Security For Flathub to succeed, we need to make sure that as we grow, we continue to be a platform that can give users confidence in the quality and security of the apps we offer. To that end, we are planning to set up infrastructure to help ensure developers are shipping the best products they possibly can to users. For example, we d like to set up automated linting and security scanning on the Flathub back-end to help developers avoid bad practices, unnecessary sandbox permissions, outdated dependencies, etc. and to keep users informed and as secure as possible. Sponsorship Fundraising is a forever task as is running such a big and growing service. We hope that one day, we can cover our costs through some modest fees built into our payments but until we reach that point, we re going to be seeking a combination of grant funding and sponsorship to keep our roadmap moving. Our hope is very much that we can encourage different organisations that buy into our vision and will benefit from Flathub to help us support it and ensure we can deliver on our goals. If you have any suggestions of who might like to support Flathub, we would be very appreciative if you could reach out and get us in touch. Finally, Thank You! Thanks to you all for reading this far and supporting the work of Flathub, and also to our major sponsors and donors without whom Flathub could not exist: GNOME Foundation, KDE e.V., Mythic Beasts, Endless Network, Fastly, and Equinix Metal via the CNCF Community Cluster. Thanks also to the tireless work of the Freedesktop SDK community to give us the runtime platform most Flatpaks depend on, particularly Seppo Yli-Olli, Codethink and others. I wanted to also give my personal thanks to a handful of dedicated people who keep Flathub working as a service and as a community: Bart omiej Piotrowski is keeping the infrastructure working essentially single-handedly (in his spare time from keeping everything running at GNOME); Kolja Lampe and Bart built the new web app and backend API for Flathub which all of the new functionality has been built on, and Filippe LeMarchand maintains the checker bot which helps keeps all of the Flatpaks up to date. And finally, all of the submissions to Flathub are reviewed to ensure quality, consistency and security by a small dedicated team of reviewers, with a huge amount of work from Hubert Figui re and Bart to keep the submissions flowing. Thanks to everyone named or unnamed for building this vision of the future of the Linux desktop together with us.

Reproducible Builds: Reproducible Builds in February 2023

Welcome to the February 2023 report from the Reproducible Builds project. As ever, if you are interested in contributing to our project, please visit the Contribute page on our website.
FOSDEM 2023 was held in Brussels on the 4th & 5th of February and featured a number of talks related to reproducibility. In particular, Akihiro Suda gave a talk titled Bit-for-bit reproducible builds with Dockerfile discussing deterministic timestamps and deterministic apt-get (original announcement). There was also an entire track of talks on Software Bill of Materials (SBOMs). SBOMs are an inventory for software with the intention of increasing the transparency of software components (the US National Telecommunications and Information Administration (NTIA) published a useful Myths vs. Facts document in 2021).
On our mailing list this month, Larry Doolittle was puzzled why the Debian verilator package was not reproducible [ ], but Chris Lamb pointed out that this was due to the use of Python s datetime.fromtimestamp over datetime.utcfromtimestamp [ ].
James Addison also was having issues with a Debian package: in this case, the alembic package. Chris Lamb was also able to identify the Sphinx documentation generator as the cause of the problem, and provided a potential patch that might fix it. This was later filed upstream [ ].
Anthony Harrison wrote to our list twice, first by introducing himself and their background and later to mention the increasing relevance of Software Bill of Materials (SBOMs):
As I am sure everyone is aware, there is a growing interest in [SBOMs] as a way of improving software security and resilience. In the last two years, the US through the Exec Order, the EU through the proposed Cyber Resilience Act (CRA) and this month the UK has issued a consultation paper looking at software security and SBOMs appear very prominently in each publication. [ ]

Tim Retout wrote a blog post discussing AlmaLinux in the context of CentOS, RHEL and supply-chain security in general [ ]:
Alma are generating and publishing Software Bill of Material (SBOM) files for every package; these are becoming a requirement for all software sold to the US federal government. What s more, they are sending these SBOMs to a third party (CodeNotary) who store them in some sort of Merkle tree system to make it difficult for people to tamper with later. This should theoretically allow end users of the distribution to verify the supply chain of the packages they have installed?

Debian

F-Droid & Android

diffoscope diffoscope is our in-depth and content-aware diff utility. Not only can it locate and diagnose reproducibility issues, it can provide human-readable diffs from many kinds of binary formats. This month, Chris Lamb released versions 235 and 236; Mattia Rizzolo later released version 237. Contributions include:
  • Chris Lamb:
    • Fix compatibility with PyPDF2 (re. issue #331) [ ][ ][ ].
    • Fix compatibility with ImageMagick version 7.1 [ ].
    • Require at least version 23.1.0 to run the Black source code tests [ ].
    • Update debian/tests/control after merging changes from others [ ].
    • Don t write test data during a test [ ].
    • Update copyright years [ ].
    • Merged a large number of changes from others.
  • Akihiro Suda edited the .gitlab-ci.yml configuration file to ensure that versioned tags are pushed to the container registry [ ].
  • Daniel Kahn Gillmor provided a way to migrate from PyPDF2 to pypdf (#1029741).
  • Efraim Flashner updated the tool metadata for isoinfo on GNU Guix [ ].
  • FC Stegerman added support for Android resources.arsc files [ ], improved a number of file-matching regular expressions [ ][ ] and added support for Android dexdump [ ]; they also fixed a test failure (#1031433) caused by Debian s black package having been updated to a newer version.
  • Mattia Rizzolo:
    • updated the release documentation [ ],
    • fixed a number of Flake8 errors [ ][ ],
    • updated the autopkgtest configuration to only install aapt and dexdump on architectures where they are available [ ], making sure that the latest diffoscope release is in a good fit for the upcoming Debian bookworm freeze.

reprotest Reprotest version 0.7.23 was uploaded to both PyPI and Debian unstable, including the following changes:
  • Holger Levsen improved a lot of documentation [ ][ ][ ], tidied the documentation as well [ ][ ], and experimented with a new --random-locale flag [ ].
  • Vagrant Cascadian adjusted reprotest to no longer randomise the build locale and use a UTF-8 supported locale instead [ ] (re. #925879, #1004950), and to also support passing --vary=locales.locale=LOCALE to specify the locale to vary [ ].
Separate to this, Vagrant Cascadian started a thread on our mailing list questioning the future development and direction of reprotest.

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:

Testing framework The Reproducible Builds project operates a comprehensive testing framework (available at tests.reproducible-builds.org) in order to check packages and other artifacts for reproducibility. In February, the following changes were made by Holger Levsen:
  • Add three new OSUOSL nodes [ ][ ][ ] and decommission the osuosl174 node [ ].
  • Change the order of listed Debian architectures to show the 64-bit ones first [ ].
  • Reduce the frequency that the Debian package sets and dd-list HTML pages update [ ].
  • Sort Tested suite consistently (and Debian unstable first) [ ].
  • Update the Jenkins shell monitor script to only query disk statistics every 230min [ ] and improve the documentation [ ][ ].

Other development work disorderfs version 0.5.11-3 was uploaded by Holger Levsen, fixing a number of issues with the manual page [ ][ ][ ].
Bernhard M. Wiedemann published another monthly report about reproducibility within openSUSE.

Louis-Philippe V ronneau: Goodbye Bullseye report from the Montreal 2023 BSP

Hello World! I haven't really had time to blog here since the start of the semester, as I've been pretty busy at work1. All this to say, this report for the Bug Squashing Party we held in Montreal last weekend is a little late, sorry :) First of all, I'm pleased to announce our local community seems to be doing great and has recovered from the pandemic-induced lull. May COVID stay away from our bodies forever. This time around, a total of 9 people made it to what has become somewhat of a biennial tradition2. We worked on a grand total of 14 bugs and even managed to close some! It looks like I was too concentrated on bugs to take a picture of the event... To redeem myself, I hereby offer you a picture of a cute-but-hairless cat I met on Sunday morning: Picture of a curious sphinx cat on a table You should try to join an upcoming BSP or to organise one if you can. It's loads of fun and you'll be helping the project make the next release happen sooner! As always, thanks to Debian for granting us a budget for the food and to rent the venue. Goodbye Bullseye!
  1. Which I guess is a good thing, since it means I actually have work this semester :O
  2. See our previous BSPs in 2017, 2019 and 2021.

Utkarsh Gupta: FOSS Activites in February 2023

Here s my (forty-first) monthly but brief update about the activities I ve done in the F/L/OSS world.

Debian
This was my 50th month of actively contributing to Debian. I became a DM in late March 2019 and a DD on Christmas 19! \o/ There s a bunch of things I do, both, technical and non-technical. Here are the things I did this month:

Uploads

Others
  • Looked up some Release team documentation.
  • Sponsored php-font-lib and php-dompdf-svg-lib for William.
  • Granted DM rights for php-dompdf.
  • Mentoring for newcomers.
  • Reviewed micro bits for Nilesh, new uploads and changes.
  • Ruby sprints.
  • Bug work (on BTS and #debian-ruby) for rails and redmine.
  • Moderation of -project mailing list.
A huge thanks to Freexian for sponsoring my Debian work and Entrouvert for sponsoring the Redmine backports. :D

Ubuntu
This was my 25th month of actively contributing to Ubuntu. Now that I joined Canonical to work on Ubuntu full-time, there s a bunch of things I do! \o/ I mostly worked on different things, I guess. I was too lazy to maintain a list of things I worked on so there s no concrete list atm. Maybe I ll get back to this section later or will start to list stuff from the fall, as I was doing before. :D

Debian (E)LTS
Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is not handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success. And Debian Extended LTS (ELTS) is its sister project, extending support to the stretch and jessie release (+2 years after LTS support). This was my forty-first month as a Debian LTS and thirty-second month as a Debian ELTS paid contributor.
I worked for 24.25 hours for LTS and 28.50 hours for ELTS.

LTS CVE Fixes and Announcements:
  • Fixed CVE-2022-47016 for tmux and uploaded to buster via 2.8-3+deb10u1.
    But decided to not roll the DLA for the package as the CVE got rejected upstream.
  • Issued DLA 3359-1, fixing CVE-2019-13038 and CVE-2021-3639, for libapache2-mod-auth-mellon.
    For Debian 10 buster, these problems have been fixed in version 0.14.2-1+deb10u1.
  • Issued DLA 3360-1, fixing CVE-2021-30151 and CVE-2022-23837, for ruby-sidekiq.
    For Debian 10 buster, these problems have been fixed in version 5.2.3+dfsg-1+deb10u1.
  • Worked on ruby-rails-html-sanitize and added notes to the security-tracker.
    TL;DR: we need newer methods in ruby-loofah to make the patches for ruby-rails-html-sanitize backportable.
  • Started to look at other set of packages meanwhile.

ELTS CVE Fixes and Announcements:
  • Issued ELA 813-1, fixing CVE-2017-12618 and CVE-2022-25147, for apr-util.
    For Debian 8 jessie, these problems have been fixed in version 1.5.4-1+deb8u1.
    For Debian 9 stretch, these problems have been fixed in version 1.5.4-3+deb9u1.
  • Issued ELA 814-1, fixing CVE-2022-39286, for jupyter-core.
    For Debian 9 stretch, these problems have been fixed in version 4.2.1-1+deb9u1.
  • Issued ELA 815-1, fixing CVE-2022-44792 and CVE-2022-44793, for net-snmp.
    For Debian 8 jessie, these problems have been fixed in version 5.7.2.1+dfsg-1+deb8u6.
    For Debian 9 stretch, these problems have been fixed in version 5.7.3+dfsg-1.7+deb9u5.
  • Helped facilitate RabbitMQ s update queries by one of our customers.
  • Started to look at other set of packages meanwhile.

Other (E)LTS Work:
Until next time.
:wq for today.

Reproducible Builds: Reproducible Builds in January 2023

Welcome to the first report for 2023 from the Reproducible Builds project! In these reports we try and outline the most important things that we have been up to over the past month, as well as the most important things in/around the community. As a quick recap, the motivation behind the reproducible builds effort is to ensure no malicious flaws can be deliberately introduced during compilation and distribution of the software that we run on our devices. As ever, if you are interested in contributing to the project, please visit our Contribute page on our website.

News In a curious turn of events, GitHub first announced this month that the checksums of various Git archives may be subject to change, specifically that because:
the default compression for Git archives has recently changed. As result, archives downloaded from GitHub may have different checksums even though the contents are completely unchanged.
This change (which was brought up on our mailing list last October) would have had quite wide-ranging implications for anyone wishing to validate and verify downloaded archives using cryptographic signatures. However, GitHub reversed this decision, updating their original announcement with a message that We are reverting this change for now. More details to follow. It appears that this was informed in part by an in-depth discussion in the GitHub Community issue tracker.
The Bundesamt f r Sicherheit in der Informationstechnik (BSI) (trans: The Federal Office for Information Security ) is the agency in charge of managing computer and communication security for the German federal government. They recently produced a report that touches on attacks on software supply-chains (Supply-Chain-Angriff). (German PDF)
Contributor Seb35 updated our website to fix broken links to Tails Git repository [ ][ ], and Holger updated a large number of pages around our recent summit in Venice [ ][ ][ ][ ].
Noak J nsson has written an interesting paper entitled The State of Software Diversity in the Software Supply Chain of Ethereum Clients. As the paper outlines:
In this report, the software supply chains of the most popular Ethereum clients are cataloged and analyzed. The dependency graphs of Ethereum clients developed in Go, Rust, and Java, are studied. These client are Geth, Prysm, OpenEthereum, Lighthouse, Besu, and Teku. To do so, their dependency graphs are transformed into a unified format. Quantitative metrics are used to depict the software supply chain of the blockchain. The results show a clear difference in the size of the software supply chain required for the execution layer and consensus layer of Ethereum.

Yongkui Han posted to our mailing list discussing making reproducible builds & GitBOM work together without gitBOM-ID embedding. GitBOM (now renamed to OmniBOR) is a project to enable automatic, verifiable artifact resolution across today s diverse software supply-chains [ ]. In addition, Fabian Keil wrote to us asking whether anyone in the community would be at Chemnitz Linux Days 2023, which is due to take place on 11th and 12th March (event info). Separate to this, Akihiro Suda posted to our mailing list just after the end of the month with a status report of bit-for-bit reproducible Docker/OCI images. As Akihiro mentions in their post, they will be giving a talk at FOSDEM in the Containers devroom titled Bit-for-bit reproducible builds with Dockerfile and that my talk will also mention how to pin the apt/dnf/apk/pacman packages with my repro-get tool.
The extremely popular Signal messenger app added upstream support for the SOURCE_DATE_EPOCH environment variable this month. This means that release tarballs of the Signal desktop client do not embed nondeterministic release information. [ ][ ]

Distribution work

F-Droid & Android There was a very large number of changes in the F-Droid and wider Android ecosystem this month: On January 15th, a blog post entitled Towards a reproducible F-Droid was published on the F-Droid website, outlining the reasons why F-Droid signs published APKs with its own keys and how reproducible builds allow using upstream developers keys instead. In particular:
In response to [ ] criticisms, we started encouraging new apps to enable reproducible builds. It turns out that reproducible builds are not so difficult to achieve for many apps. In the past few months we ve gotten many more reproducible apps in F-Droid than before. Currently we can t highlight which apps are reproducible in the client, so maybe you haven t noticed that there are many new apps signed with upstream developers keys.
(There was a discussion about this post on Hacker News.) In addition:
  • F-Droid added 13 apps published with reproducible builds this month. [ ]
  • FC Stegerman outlined a bug where baseline.profm files are nondeterministic, developed a workaround, and provided all the details required for a fix. As they note, this issue has now been fixed but the fix is not yet part of an official Android Gradle plugin release.
  • GitLab user Parwor discovered that the number of CPU cores can affect the reproducibility of .dex files. [ ]
  • FC Stegerman also announced the 0.2.0 and 0.2.1 releases of reproducible-apk-tools, a suite of tools to help make .apk files reproducible. Several new subcommands and scripts were added, and a number of bugs were fixed as well [ ][ ]. They also updated the F-Droid website to improve the reproducibility-related documentation. [ ][ ]
  • On the F-Droid issue tracker, FC Stegerman discussed reproducible builds with one of the developers of the Threema messenger app and reported that Android SDK build-tools 31.0.0 and 32.0.0 (unlike earlier and later versions) have a zipalign command that produces incorrect padding.
  • A number of bugs related to reproducibility were discovered in Android itself. Firstly, the non-deterministic order of .zip entries in .apk files [ ] and then newline differences between building on Windows versus Linux that can make builds not reproducible as well. [ ] (Note that these links may require a Google account to view.)
  • And just before the end of the month, FC Stegerman started a thread on our mailing list on the topic of hiding data/code in APK embedded signatures which has been made possible by the Android APK Signature Scheme v2/v3. As part of this, they made an Android app that reads the APK Signing block of its own APK and extracts a payload in order to alter its behaviour called sigblock-code-poc.

Debian As mentioned in last month s report, Vagrant Cascadian has been organising a series of online sprints in order to clear the huge backlog of reproducible builds patches submitted by performing NMUs (Non-Maintainer Uploads). During January, a sprint took place on the 10th, resulting in the following uploads: During this sprint, Holger Levsen filed Debian bug #1028615 to request that the tracker.debian.org service display results of reproducible rebuilds, not just reproducible CI results. Elsewhere in Debian, strip-nondeterminism is our tool to remove specific non-deterministic results from a completed build. This month, version 1.13.1-1 was uploaded to Debian unstable by Holger Levsen, including a fix by FC Stegerman (obfusk) to update a regular expression for the latest version of file(1) [ ]. (#1028892) Lastly, 65 reviews of Debian packages were added, 21 were updated and 35 were removed this month adding to our knowledge about identified issues.

Other distributions In other distributions:

diffoscope diffoscope is our in-depth and content-aware diff utility. Not only can it locate and diagnose reproducibility issues, it can provide human-readable diffs from many kinds of binary formats. This month, Chris Lamb made the following changes to diffoscope, including preparing and uploading versions 231, 232, 233 and 234 to Debian:
  • No need for from __future__ import print_function import anymore. [ ]
  • Comment and tidy the extras_require.json handling. [ ]
  • Split inline Python code to generate test Recommends into a separate Python script. [ ]
  • Update debian/tests/control after merging support for PyPDF support. [ ]
  • Correctly catch segfaulting cd-iccdump binary. [ ]
  • Drop some old debugging code. [ ]
  • Allow ICC tests to (temporarily) fail. [ ]
In addition, FC Stegerman (obfusk) made a number of changes, including:
  • Updating the test_text_proper_indentation test to support the latest version(s) of file(1). [ ]
  • Use an extras_require.json file to store some build/release metadata, instead of accessing the internet. [ ]
  • Updating an APK-related file(1) regular expression. [ ]
  • On the diffoscope.org website, de-duplicate contributors by e-mail. [ ]
Lastly, Sam James added support for PyPDF version 3 [ ] and Vagrant Cascadian updated a handful of tool references for GNU Guix. [ ][ ]

Upstream patches The Reproducible Builds project attempts to fix as many currently-unreproducible packages as possible. This month, we wrote a large number of such patches, including:

Testing framework The Reproducible Builds project operates a comprehensive testing framework at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In January, the following changes were made by Holger Levsen:
  • Node changes:
  • Debian-related changes:
    • Only keep diffoscope s HTML output (ie. no .json or .txt) for LTS suites and older in order to save diskspace on the Jenkins host. [ ]
    • Re-create pbuilder base less frequently for the stretch, bookworm and experimental suites. [ ]
  • OpenWrt-related changes:
    • Add gcc-multilib to OPENWRT_HOST_PACKAGES and install it on the nodes that need it. [ ]
    • Detect more problems in the health check when failing to build OpenWrt. [ ]
  • Misc changes:
    • Update the chroot-run script to correctly manage /dev and /dev/pts. [ ][ ][ ]
    • Update the Jenkins shell monitor script to collect disk stats less frequently [ ] and to include various directory stats. [ ][ ]
    • Update the real year in the configuration in order to be able to detect whether a node is running in the future or not. [ ]
    • Bump copyright years in the default page footer. [ ]
In addition, Christian Marangi submitted a patch to build OpenWrt packages with the V=s flag to enable debugging. [ ]

Valhalla's Things: How To Verify Debian's ARM Installer Images

Posted on February 2, 2023
Thanks to Vagrant on the debian-arm mailing list I ve found that there is a chain of verifiability for the images usually used to install Debian on ARM devices. It s not trivial, so I m writing it down for future reference when I ll need it again.
  1. Download the images from https://ftp.debian.org/debian/dists/bullseye/main/installer-armhf/current/images/ (choose either hd-media or netboot, then SD-card-images and download the firmware.* file for your board as well as partition.img.gz).
  2. Download the checksums file https://ftp.debian.org/debian/dists/bullseye/main/installer-armhf/current/images/SHA256SUMS
  3. Download the Release file from https://ftp.debian.org/debian/dists/bullseye/ ; for convenience the InRelease
  4. Verify the Release file: 
    gpg --no-default-keyring \
    --keyring /usr/share/keyrings/debian-archive-bullseye-stable.gpg \
    --verify InRelease
  5. Verify the checksums file: 
    awk '/installer-armhf\/current\/images\/SHA256SUMS/  print $1 "
SHA256SUMS" ' InRelease   tail -n 1   sha256sum -c
    (I know, I probably can use awk instead of that tail, but it s getting late and I want to publish this).
  6. Verify the actual files, for hd-media: 
    grep hd-media SHA256SUMS \
  sed 's#hd-media/SD-card-images/##' \
  sha256sum -c \
  grep -v "No such file or directory" \
  grep -v "FAILED open or read" 2> /dev/null
    and for netboot: 
    grep netboot SHA256SUMS \
  sed 's#netboot/SD-card-images/##' \
  sha256sum -c \
  grep -v "No such file or directory" \
  grep -v "FAILED open or read" 2> /dev/null
    and check that all of the files you wanted are there with an OK; of course change hd-media with netboot as needed.
And I fully agree that fewer steps would be nice, but this is definitely better than nothing!

Reproducible Builds (diffoscope): diffoscope 233 released

The diffoscope maintainers are pleased to announce the release of diffoscope version 233. This version includes the following changes: 
[ FC Stegerman ]
* Split packaging metadata into an extras_require.json file instead of using
  the pep517 and the pip modules directly. This was causing build failures if
  not using a virtualenv and/or building without internet access.
  (Closes: #1029066, reproducible-builds/diffoscope#325)
[ Vagrant Cascadian ]
* Add an external tool reference for GNU Guix (lzip).
* Drop an external tool reference for GNU Guix (pedump).
[ Chris Lamb ]
* Split inline Python code in shell script to generate test dependencies to a
  separate Python script.
* No need for "from __future__ import print_function" import in setup.py
  anymore.
* Comment and tidy the new extras_require.json handling.

Reproducible Builds: Reproducible Builds in December 2022

Welcome to the December 2022 report from the Reproducible Builds project.
We are extremely pleased to announce that the dates for the Reproducible Builds Summit in 2023 have been announced in 2022 already: We plan to spend three days continuing to the grow of the Reproducible Builds effort. As in previous events, the exact content of the meeting will be shaped by the participants. And, as mentioned in Holger Levsen s post to our mailing list, the dates have been booked and confirmed with the venue, so if you are considering attending, please reserve these dates in your calendar today.
R my Gr nblatt, an associate professor in the T l com Sud-Paris engineering school wrote up his pain points of using Nix and NixOS. Although some of the points do not touch on reproducible builds, R my touches on problems he has encountered with the different kinds of reproducibility that these distributions appear to promise including configuration files affecting the behaviour of systems, the fragility of upstream sources as well as the conventional idea of binary reproducibility.
Morten Linderud reported that he is quietly optimistic that if Go programming language resolves all of its issues with reproducible builds (tracking issue) then the Go binaries distributed from Google and by Arch Linux may be bit-for-bit identical. It s just a bit early to sorta figure out what roadblocks there are. [But] Go bootstraps itself every build, so in theory I think it should be possible.
On December 15th, Holger Levsen published an in-depth interview he performed with David A. Wheeler on supply-chain security and reproducible builds, but it also touches on the biggest challenges in computing as well. This is part of a larger series of posts featuring the projects, companies and individuals who support the Reproducible Builds project. Other instalments include an article featuring the Civil Infrastructure Platform project and followed this up with a post about the Ford Foundation as well as a recent ones about ARDC, the Google Open Source Security Team (GOSST), Jan Nieuwenhuizen on Bootstrappable Builds, GNU Mes and GNU Guix and Hans-Christoph Steiner of the F-Droid project.
A number of changes were made to the Reproducible Builds website and documentation this month, including FC Stegerman adding an F-Droid/apksigcopier example to our embedded signatures page [ ], Holger Levsen making a large number of changes related to the 2022 summit in Venice as well as 2023 s summit in Hamburg [ ][ ][ ][ ] and Simon Butler updated our publications page [ ][ ].
On our mailing list this month, James Addison asked a question about whether there has been any effort to trace the files used by a build system in order to identify the corresponding build-dependency packages. [ ] In addition, Bernhard M. Wiedemann then posed a thought-provoking question asking How to talk to skeptics? , which was occasioned by a colleague who had published a blog post in May 2021 skeptical of reproducible builds. The thread generated a number of replies.

Android news obfusk (FC Stegerman) performed a thought-provoking review of tools designed to determine the difference between two different .apk files shipped by a number of free-software instant messenger applications. These scripts are often necessary in the Android/APK ecosystem due to these files containing embedded signatures so the conventional bit-for-bit comparison cannot be used. After detailing a litany of issues with these tools, they come to the conclusion that:
It s quite possible these messengers actually have reproducible builds, but the verification scripts they use don t actually allow us to verify whether they do.
This reflects the consensus view within the Reproducible Builds project: pursuing a situation in language or package ecosystems where binaries are bit-for-bit identical (over requiring a bespoke ecosystem-specific tool) is not a luxury demanded by purist engineers, but rather the only practical way to demonstrate reproducibility. obfusk also announced the first release of their own set of tools on our mailing list. Related to this, obfusk also posted to an issue filed against Mastodon regarding the difficulties of creating bit-by-bit identical APKs, especially with respect to copying v2/v3 APK signatures created by different tools; they also reported that some APK ordering differences were not caused by building on macOS after all, but by using Android Studio [ ] and that F-Droid added 16 more apps published with Reproducible Builds in December.

Debian As mentioned in last months report, Vagrant Cascadian has been organising a series of online sprints in order to clear the huge backlog of reproducible builds patches submitted by performing NMUs (Non-Maintainer Uploads). During December, meetings were held on the 1st, 8th, 15th, 22nd and 29th, resulting in a large number of uploads and bugs being addressed: The next sprint is due to take place this coming Tuesday, January 10th at 16:00 UTC.

Upstream patches The Reproducible Builds project attempts to fix as many currently-unreproducible packages as possible. This month, we wrote a large number of such patches, including:

Testing framework The Reproducible Builds project operates a comprehensive testing framework at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In October, the following changes were made by Holger Levsen:
  • The osuosl167 machine is no longer a openqa-worker node anymore. [ ][ ]
  • Detect problems with APT repository signatures [ ] and update a repository signing key [ ].
  • reproducible Debian builtin-pho: improve job output. [ ]
  • Only install the foot-terminfo package on Debian systems. [ ]
In addition, Mattia Rizzolo added support for the version of diffoscope in Debian stretch which doesn t support the --timeout flag. [ ][ ]

diffoscope diffoscope is our in-depth and content-aware diff utility. Not only can it locate and diagnose reproducibility issues, it can provide human-readable diffs from many kinds of binary formats. This month, Chris Lamb made the following changes to diffoscope, including preparing and uploading versions 228, 229 and 230 to Debian:
  • Fix compatibility with file(1) version 5.43, with thanks to Christoph Biedl. [ ]
  • Skip the test_html.py::test_diff test if html2text is not installed. (#1026034)
  • Update copyright years. [ ]
In addition, Jelle van der Waa added support for Berkeley DB version 6. [ ] Orthogonal to this, Holger Levsen bumped the Debian Standards-Version on all of our packages, including diffoscope [ ], strip-nondeterminism [ ], disorderfs [ ] and reprotest [ ].

Chris Lamb: Favourite books of 2022: Memoir/biography

In my two most recent posts, I listed the fiction and classic fiction I enjoyed the most in 2022. I'll leave my roundup of general non-fiction until tomorrow, but today I'll be going over my favourite memoirs and biographies, in no particular order. Books that just missed the cut here include Roisin Kiberd's The Disconnect: A Personal Journey Through the Internet (2019), Steve Richards' The Prime Ministers (2019) which reflects on UK leadership from Harold Wilson to Boris Johnson, Robert Graves Great War memoir Goodbye to All That (1929) and David Mikics's portrait of Stanley Kubrick called American Filmmaker.

Afropean: Notes from Black Europe (2019) Johny Pitts Johny Pitts is a photographer and writer who lives in the north of England who set out to explore "black Europe from the street up" those districts within European cities that, although they were once 'white spaces' in the past, they are now occupied by Black people. Unhappy with the framing of the Black experience back home in post-industrial Sheffield, Pitts decided to become a nomad and goes abroad to seek out the sense of belonging he cannot find in post-Brexit Britain, and Afropean details his journey through Paris, Brussels, Lisbon, Berlin, Stockholm and Moscow. However, Pitts isn't just avoiding the polarisation and structural racism embedded in contemporary British life. Rather, he is seeking a kind of super-national community that transcends the reductive and limiting nationalisms of all European countries, most of which have based their national story on a self-serving mix of nostalgia and postcolonial fairy tales. Indeed, the term 'Afropean' is the key to understanding the goal of this captivating memoir. Pitts writes at the beginning of this book that the word wasn't driven only as a response to the crude nativisms of Nigel Farage and Marine Le Pen, but that it:
encouraged me to think of myself as whole and unhyphenated. [ ] Here was a space where blackness was taking part in shaping European identity at large. It suggested the possibility of living in and with more than one idea: Africa and Europe, or, by extension, the Global South and the West, without being mixed-this, half-that or black-other. That being black in Europe didn t necessarily mean being an immigrant.
In search of this whole new theory of home, Pitts travels to the infamous banlieue of Clichy-sous-Bois just to the East of Paris, thence to Matong in Brussels, as well as a quick and abortive trip into Moscow and other parallel communities throughout the continent. In these disparate environs, Pitts strikes up countless conversations with regular folk in order to hear their quotidian stories of living, and ultimately to move away from the idea that Black history is defined exclusively by slavery. Indeed, to Pitts, the idea of race is one that ultimately restricts one's humanity; the concept "is often forced to embody and speak for certain ideas, despite the fact it can't ever hold in both hands the full spectrum of a human life and the cultural nuances it creates." It's difficult to do justice to the effectiveness of the conversations Pitts has throughout his travels, but his shrewd attention to demeanour, language, raiment and expression vividly brings alive the people he talks to. Of related interest to fellow Brits as well are the many astute observations and comparisons with Black and working-class British life. The tone shifts quite often throughout this book. There might be an amusing aside one minute, such as the portrait of an African American tourist in Paris to whom "the whole city was a film set, with even its homeless people appearing to him as something oddly picturesque." But the register abruptly changes when he visits Clichy-sous-Bois on an anniversary of important to the area, and an element of genuine danger is introduced when Johny briefly visits Moscow and barely gets out alive. What's especially remarkable about this book is there is a freshness to Pitt s treatment of many well-worn subjects. This can be seen in his account of Belgium under the reign of Leopold II, the history of Portuguese colonialism (actually mostly unknown to me), as well in the way Pitts' own attitude to contemporary anti-fascist movements changes throughout an Antifa march. This chapter was an especial delight, and not only because it underlined just how much of Johny's trip was an inner journey of an author willing have his mind changed. Although Johny travels alone throughout his journey, in the second half of the book, Pitts becomes increasingly accompanied by a number of Black intellectuals by the selective citing of Frantz Fanon and James Baldwin and Caryl Phillips. (Nevertheless, Jonny has also brought his camera for the journey as well, adding a personal touch to this already highly-intimate book.) I suspect that his increasing exercise of Black intellectual writing in the latter half of the book may be because Pitts' hopes about 'Afropean' existence ever becoming a reality are continually dashed and undercut. The unity among potential Afropeans appears more-and-more unrealisable as the narrative unfolds, the various reasons of which Johny explores both prosaically and poetically. Indeed, by the end of the book, it's unclear whether Johny has managed to find what he left the shores of England to find. But his mix of history, sociology and observation of other cultures right on my doorstep was something of a revelation to me.

Orwell's Roses (2021) Rebecca Solnit Orwell s Roses is an alternative journey through the life and afterlife of George Orwell, reimaging his life primarily through the lens of his attentiveness to nature. Yet this framing of the book as an 'alternative' history is only revisionist if we compare it to the usual view of Orwell as a bastion of 'free speech' and English 'common sense' the roses of the title of this book were very much planted by Orwell in his Hertfordshire garden in 1936, and his yearning of nature one was one of the many constants throughout his life. Indeed, Orwell wrote about wildlife and outdoor life whenever he could get away with it, taking pleasure in a blackbird's song and waxing nostalgically about the English countryside in his 1939 novel Coming Up for Air (reviewed yesterday).
By sheer chance, I actually visited this exact garden immediately to the publication of this book
Solnit has a particular ability to evince unexpected connections between Orwell and the things he was writing about: Joseph Stalin's obsession with forcing lemons to grow in ludicrously cold climates; Orwell s slave-owning ancestors in Jamaica; Jamaica Kincaid's critique of colonialism in the flower garden; and the exploitative rose industry in Colombia that supplies the American market. Solnit introduces all of these new correspondences in a voice that feels like a breath of fresh air after decades of stodgy Orwellania, and without lapsing into a kind of verbal soft-focus. Indeed, the book displays a marked indifference towards the usual (male-centric) Orwell fandom. Her book draws to a close with a rereading of the 'dystopian' Nineteen Eighty-Four that completes her touching portrait of a more optimistic and hopeful Orwell, as well as a reflection on beauty and a manifesto for experiencing joy as an act of resistance.

The Disaster Artist (2013) Greg Sestero & Tom Bissell For those not already in the know, The Room was a 2003 film by director-producer-writer-actor Tommy Wiseau, an inscrutable Polish immigr with an impenetrable background, an idiosyncratic choice of wardrobe and a mysterious large source of income. The film, which centres on a melodramatic love triangle, has since been described by several commentators and publications as one of the worst films ever made. Tommy's production completely bombed at the so-called 'box office' (the release was actually funded entirely by Wiseau personally), but the film slowly became a favourite at cult cinema screenings. Given Tommy's prominent and central role in the film, there was always an inherent cruelty involved in indulging in the spectacle of The Room the audience was laughing because the film was astonishingly bad, of course, but Wiseau infused his film with sincere earnestness that in a heartless twist of irony may be precisely why it is so terrible to begin with. Indeed, it should be stressed that The Room is not simply a 'bad' film, and therefore not worth paying any attention to: it is uncannily bad in a way that makes it eerily compelling to watch. It unintentionally subverts all the rules of filmmaking in a way that captivates the attention. Take this representative example:
This thirty-six-second scene showcases almost every problem in The Room: the acting, the lighting, the sound design, the pacing, the dialogue and that this unnecessary scene (which does not advance the plot) even exists in the first place. One problem that the above clip doesn't capture, however, is Tommy's vulnerable ego. (He would later make the potentially conflicting claims that The Room was both an ironic cult success and that he is okay with people interpreting it sincerely). Indeed, the filmmaker's central role as Johnny (along with his Willy-Wonka meets Dracula persona) doesn't strike viewers as yet another vanity project, it actually asks more questions than it answers. Why did Tommy even make this film? What is driving him psychologically? And why and how? is he so spellbinding? On the surface, then, 2013's The Disaster Artist is a book about the making of one the strangest films ever made, written by The Room's co-star Greg Sestero and journalist Tom Bissell. Naturally, you learn some jaw-dropping facts about the production and inspiration of the film, the seed of which was planted when Greg and Tommy went to see an early screening of The Talented Mr Ripley (1999). It turns out that Greg's character in The Room is based on Tommy's idiosyncratic misinterpretation of its plot, extending even to the character's name Mark who, in textbook Tommy style, was taken directly (or at least Tommy believed) from one of Ripley's movie stars: "Mark Damon" [sic]. Almost as absorbing as The Room itself, The Disaster Artist is partly a memoir about Thomas P. Wiseau and his cinematic masterpiece. But it could also be described as a biography about a dysfunctional male relationship and, almost certainly entirely unconsciously, a text about the limitations of hetronormativity. It is this latter element that struck me the most whilst reading this book: if you take a step back for a moment, there is something uniquely sad about Tommy's inability to connect with others, and then, when Wiseau poured his soul into his film people just laughed. Despite the stories about his atrocious behaviour both on and off the film set, there's something deeply tragic about the whole affair. Jean-Luc Godard, who passed away earlier this year, once observed that every fictional film is a documentary of its actors. The Disaster Artist shows that this well-worn aphorism doesn't begin to cover it.

Russ Allbery: Review: Shutdown

Review: Shutdown, by Adam Tooze
Publisher: Viking
Copyright: September 2021
ISBN: 0-593-29756-3
Format: Kindle
Pages: 305
Shutdown is a history of the world macroeconomic response to COVID-19, covering 2020 and the very beginning of 2021. But wait, you might be saying. It's only the end of 2022 right now, and this book was published in September of 2021. That's not history, that's journalism. And yes, I think that's a valid critique. Shutdown is doing something rather odd, and I'm not certain it was a good idea, but I do think it has a (somewhat narrow) audience. Descriptions first. After an awkward introduction (more on that later), Tooze launches into an essentially chronological history in four parts: the initial viral spread and early political and public health response, the economic hard stop and macroeconomic response, the summer fallout and political complications, and the more-organized aftershocks of the fall. The early chapters are closer to a history, with a clear timeline and the tracery of cause and effect. The closer the narrative comes to the time Tooze was writing it, the more that clarity drops away. The last few chapters feel like a collection of simultaneous events that may or may not be related or have long-term significance. Everyone reading this lived through those events, and if you're at all like me, consumed far more news coverage of them than was healthy. The obvious question, then, is why read a book that rehashes all of that? For me, there are two answers: Tooze pays attention to more of the world than makes it into the local headlines and tries to synthesize a larger picture, and the focus of this book is the macroeconomic facilities used in the response. I remember the fights over school closures in the US. I didn't know about the impact of unprecedented Federal Reserve action on the bond market for emerging market government debt. If you're the sort of person who reads The Economist religiously (which I am not), you may not learn anything new here. If you're not, and you have a general interest in international finance, there were probably some wrinkles you missed. Even if you stay up-to-date on the more technical news, Shutdown provides an intermediate consolidation and restructuring. It's not ready to be a history in the traditional sense, but it's a first pass at putting events in order and tracing the implications for the global financial system. Read in that sense, Shutdown felt like a continuation of Tooze's Crashed, following the same themes of a hegemonic but unstable dollar system and a Federal Reserve that has increasingly taken on the role of backstop to the entire world (and how the only tools it has available tend to increase wealth inequality). If you've not read Crashed, read it first. I think it's the stronger and more thorough book (not the least because it had more time and data to construct a coherent history), and it's the best introduction to the international macroeconomic risks that Tooze traces in Shutdown. This book was, for me, an update of the Tooze's thinking in Crashed for the COVID era. Tooze is very good at clearly describing macroeconomic shocks. I recently read Lev Menand's The Fed Unbound, which is in part about the same intervention during the COVID shock that Tooze describes here, and yet it wasn't until I read Shutdown that I grasped that the Treasury purchases by the Fed had arguably crossed the political red line of monetizing government debt, even though the Fed probably had no choice and few people noticed in the middle of the crisis. This is where Tooze's background as a historian is helpful. Most people writing on this topic are either economists, who seem to take inferences like that for granted and dive into the technical debate, or journalists, who rarely understand the nuance and often jump to facile conclusions. Tooze is a historian with an extensive economics background; he can explain the mechanics while still focusing on the limitations of politics, which is the sort of analysis that I want to read. The problem with this book as a history is that it necessarily raises more questions than it answers. In the conclusion, Tooze writes:
A severe tightening in U.S. monetary policy or even a full-fledged taper tantrum would put global resilience to a stern test. So too would a violent escalation of geopolitical tension in one of the major regions of the world economy.
Both of those events have subsequently happened, which throws any tentative conclusions Tooze can offer into question. For another example, when Tooze wrote Shutdown, China's zero COVID policy was widely celebrated inside China and had enabled a fast economic recovery while the rest of the world was still in serious difficulty. Before Omicron, it was conceivable (if extremely risky) that China could continue to avoid a major COVID surge. In December of 2022, it's obvious they only managed to delay, and while delay meant vaccination and the price in deaths may well be smaller than was paid for the route taken by most of the rest of the world, the trade-offs are now even harder to analyze. There are, of course, other examples, the most obvious of which is the rise of global inflation simultaneous with a strengthening dollar. A history written from a distance of several decades would have included that aftermath. A snap history with a distance of only a few months cannot. The other problem with this book is that it's not as polished. Viking did an amazing job turning publication around in roughly six months, dramatically faster than publishing normally works, but there are parts that could have used more editing. The introduction, in particular, reads more like a blog post than an edited book, and while I'm a happy reader of Tooze's Chartbook, the recap of COVID's impact was a bit trite and Tooze's abstract musings on polycrisis could have used tightening and clarity. The meat of the book is better, but there is a messy stream-of-consciousness feel that is inherent in a book written to this tight of a timeline. I think the audience of this book is, narrowly, people who have read Crashed and want to follow that line of reasoning into the COVID era. Crashed is one of the better books on macroeconomic history that I've read, and I did indeed want to follow that train of thought, so I am part of that audience. This is not the sort of book that I would widely recommend, however. If you want to read it, you probably know that already; if you are new to Tooze's analysis, Crashed is the place to start.

Jonathan McDowell: Setting up FreshRSS in a subdirectory

Ever since the demise of Google Reader I have been looking for a suitable replacement RSS reader. In the past I used to use Liferea but that was when I used a single desktop machine; these days I want to be able to read on my phone and multiple machines. I moved to Feedly and it s been mostly ok, but I m hitting the limit of feeds available in the free tier, and $72/year is a bit more than I can justify to myself. Especially when I have machines already available to me where I could self host something. The problem, of course, is what to host. It seems the best options are all written in PHP, so I had to get over my adverse knee-jerk reaction to that. I ended up on FreshRSS but if it hadn t worked out I d have tried TinyTinyRSS. Of course I m hosting on Debian, and the machine I chose to use was already running nginx and PostgreSQL. So I needed to install PHP: 
$ sudo apt install php7.4-fpm php-curl php-gmp php-intl php-mbstring \
	php-pgsql php-xml php-zip
I put my FreshRSS install in /srv/freshrss so I grabbed the 1.20.2 release from GitHub (actually 1.20.1 at the time, but I ve upgraded to the latest since) and untared it in there. I gave www-data access to the data directory (sudo chown -R www-data /srv/freshrss/data) (yes, yes, I could have created a new user specifically for FreshRSS, but I ve chosen not to for now). There s no actual need to configure things up on the filesystem, you can do the initial setup from the web interface. Which is where the trouble came. I ve been an Apache user since 1998 and as a result it s what I know and what I go to. nginx is new to me. And I wanted my FreshRSS instance to live in a subdirectory of an existing TLS-enabled host, rather than have it s own hostname. Now, at least FreshRSS copes with this (unlike far too many other projects), you just have to configure your webserver correctly. Which took me more experimentation than I d like, but I ve ended up with the following snippet: 
    # PHP files handling
    location ~ ^/freshrss/.+?\.php(/.*)?$  
        root /srv/freshrss/p;
        fastcgi_pass unix:/run/php/php-fpm.sock;
        fastcgi_split_path_info ^/freshrss(/.+\.php)(/.*)?$;
        set $path_info $fastcgi_path_info;
        fastcgi_param PATH_INFO $path_info;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
     
    location ~ ^/freshrss(/.*)?$  
        root /srv/freshrss/p;
        try_files $1 /freshrss$1/index.php$is_args$args;
Other than the addition of the freshrss prefix this ends up differing slightly from the FreshRSS webserver configuration example. I ended up having to make the path info on the fastcgi_split_path_info optional, and my try_files in the bare directory location directive needed $is_args$args added or I just ended up in a redirect loop because the session parameters didn t get passed through. I m sure there s a better way to do it, but I did a bunch of searching and this is how I ended up making it work. Before firing up the web configuration I created a suitable database: 
$ sudo -Hu postgres psql
psql (13.8 (Debian 13.8-0+deb11u1))
Type "help" for help.
postgres=# create database freshrss;
CREATE DATABASE
postgres=# create user freshrss with encrypted password 'hunter2';
CREATE ROLE
postgres=# grant all privileges on database freshrss to freshrss;
GRANT
postgres=# \q
I ran through the local configuration, creating myself a user and adding some feeds, then created a cronjob to fetch updates hourly and keep a log: 
# mkdir /var/log/freshrss
# chown :www-data /var/log/freshrss
# chmod 775 /var/log/freshrss
# cat > /etc/cron.d/freshrss-refresh <EOF

Experiences so far? Reasonably happy. The interface seems snappy enough, and works well both on mobile and desktop. I m only running a single user instance at present, but am considering opening it up to some other folk and will see how that scales. And it clearly indicated a number of my feeds that were broken, so I ve cleaned some up that are still around and deleted the missing ones. Now I just need to figure out what else I should be subscribed to that I ve been putting off due to the Feedly limit!

Reproducible Builds: Reproducible Builds in November 2022

Welcome to yet another report from the Reproducible Builds project, this time for November 2022. In all of these reports (which we have been publishing regularly since May 2015) we attempt to outline the most important things that we have been up to over the past month. As always, if you interested in contributing to the project, please visit our Contribute page on our website.

Reproducible Builds Summit 2022 Following-up from last month s report about our recent summit in Venice, Italy, a comprehensive report from the meeting has not been finalised yet watch this space! As a very small preview, however, we can link to several issues that were filed about the website during the summit (#38, #39, #40, #41, #42, #43, etc.) and collectively learned about Software Bill of Materials (SBOM) s and how .buildinfo files can be seen/used as SBOMs. And, no less importantly, the Reproducible Builds t-shirt design has been updated

Reproducible Builds at European Cyber Week 2022 During the European Cyber Week 2022, a Capture The Flag (CTF) cybersecurity challenge was created by Fr d ric Pierret on the subject of Reproducible Builds. The challenge consisted in a pedagogical sense based on how to make a software release reproducible. To progress through the challenge issues that affect the reproducibility of build (such as build path, timestamps, file ordering, etc.) were to be fixed in steps in order to get the final flag in order to win the challenge. At the end of the competition, five people succeeded in solving the challenge, all of whom were awarded with a shirt. Fr d ric Pierret intends to create similar challenge in the form of a how to in the Reproducible Builds documentation, but two of the 2022 winners are shown here:

On business adoption and use of reproducible builds Simon Butler announced on the rb-general mailing list that the Software Quality Journal published an article called On business adoption and use of reproducible builds for open and closed source software. This article is an interview-based study which focuses on the adoption and uses of Reproducible Builds in industry, with a focus on investigating the reasons why organisations might not have adopted them:
[ ] industry application of R-Bs appears limited, and we seek to understand whether awareness is low or if significant technical and business reasons prevent wider adoption.
This is achieved through interviews with software practitioners and business managers, and touches on both the business and technical reasons supporting the adoption (or not) of Reproducible Builds. The article also begins with an excellent explanation and literature review, and even introduces a new helpful analogy for reproducible builds:
[Users are] able to perform a bitwise comparison of the two binaries to verify that they are identical and that the distributed binary is indeed built from the source code in the way the provider claims. Applied in this manner, R-Bs function as a canary, a mechanism that indicates when something might be wrong, and offer an improvement in security over running unverified binaries on computer systems.
The full paper is available to download on an open access basis. Elsewhere in academia, Beatriz Michelson Reichert and Rafael R. Obelheiro have published a paper proposing a systematic threat model for a generic software development pipeline identifying possible mitigations for each threat (PDF). Under the Tampering rubric of their paper, various attacks against Continuous Integration (CI) processes:
An attacker may insert a backdoor into a CI or build tool and thus introduce vulnerabilities into the software (resulting in an improper build). To avoid this threat, it is the developer s responsibility to take due care when making use of third-party build tools. Tampered compilers can be mitigated using diversity, as in the diverse double compiling (DDC) technique. Reproducible builds, a recent research topic, can also provide mitigation for this problem. (PDF)

Misc news
On our mailing list this month:

Debian & other Linux distributions Over 50 reviews of Debian packages were added this month, another 48 were updated and almost 30 were removed, all of which adds to our knowledge about identified issues. Two new issue types were added as well. [ ][ ]. Vagrant Cascadian announced on our mailing list another online sprint to help clear the huge backlog of reproducible builds patches submitted by performing NMUs (Non-Maintainer Uploads). The first such sprint took place on September 22nd, but others were held on October 6th and October 20th. There were two additional sprints that occurred in November, however, which resulted in the following progress: Lastly, Roland Clobus posted his latest update of the status of reproducible Debian ISO images on our mailing list. This reports that all major desktops build reproducibly with bullseye, bookworm and sid as well as that no custom patches needed to applied to Debian unstable for this result to occur. During November, however, Roland proposed some modifications to live-setup and the rebuild script has been adjusted to fix the failing Jenkins tests for Debian bullseye [ ][ ].
In other news, Miro Hron ok proposed a change to clamp build modification times to the value of SOURCE_DATE_EPOCH. This was initially suggested and discussed on a devel@ mailing list post but was later written up on the Fedora Wiki as well as being officially proposed to Fedora Engineering Steering Committee (FESCo).

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:

diffoscope diffoscope is our in-depth and content-aware diff utility. Not only can it locate and diagnose reproducibility issues, it can provide human-readable diffs from many kinds of binary formats. This month, Chris Lamb prepared and uploaded versions 226 and 227 to Debian:
  • Support both python3-progressbar and python3-progressbar2, two modules providing the progressbar Python module. [ ]
  • Don t run Python decompiling tests on Python bytecode that file(1) cannot detect yet and Python 3.11 cannot unmarshal. (#1024335)
  • Don t attempt to attach text-only differences notice if there are no differences to begin with. (#1024171)
  • Make sure we recommend apksigcopier. [ ]
  • Tidy generation of os_list. [ ]
  • Make the code clearer around generating the Debian substvars . [ ]
  • Use our assert_diff helper in test_lzip.py. [ ]
  • Drop other copyright notices from lzip.py and test_lzip.py. [ ]
In addition to this, Christopher Baines added lzip support [ ], and FC Stegerman added an optimisation whereby we don t run apktool if no differences are detected before the signing block [ ].
A significant number of changes were made to the Reproducible Builds website and documentation this month, including Chris Lamb ensuring the openEuler logo is correctly visible with a white background [ ], FC Stegerman de-duplicated by email address to avoid listing some contributors twice [ ], Herv Boutemy added Apache Maven to the list of affiliated projects [ ] and boyska updated our Contribute page to remark that the Reproducible Builds presence on salsa.debian.org is not just the Git repository but is also for creating issues [ ][ ]. In addition to all this, however, Holger Levsen made the following changes:
  • Add a number of existing publications [ ][ ] and update metadata for some existing publications as well [ ].
  • Hide draft posts on the website homepage. [ ]
  • Add the Warpforge build tool as a participating project of the summit. [ ]
  • Clarify in the footer that we welcome patches to the website repository. [ ]

Testing framework The Reproducible Builds project operates a comprehensive testing framework at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In October, the following changes were made by Holger Levsen:
  • Improve the generation of meta package sets (used in grouping packages for reporting/statistical purposes) to treat Debian bookworm as equivalent to Debian unstable in this specific case [ ] and to parse the list of packages used in the Debian cloud images [ ][ ][ ].
  • Temporarily allow Frederic to ssh(1) into our snapshot server as the jenkins user. [ ]
  • Keep some reproducible jobs Jenkins logs much longer [ ] (later reverted).
  • Improve the node health checks to detect failures to update the Debian cloud image package set [ ][ ] and to improve prioritisation of some kernel warnings [ ].
  • Always echo any IRC output to Jenkins output as well. [ ]
  • Deal gracefully with problems related to processing the cloud image package set. [ ]
Finally, Roland Clobus continued his work on testing Live Debian images, including adding support for specifying the origin of the Debian installer [ ] and to warn when the image has unmet dependencies in the package list (e.g. due to a transition) [ ].

Matthew Garrett: Making unphishable 2FA phishable

One of the huge benefits of WebAuthn is that it makes traditional phishing attacks impossible. An attacker sends you a link to a site that looks legitimate but isn't, and you type in your credentials. With SMS or TOTP-based 2FA, you type in your second factor as well, and the attacker now has both your credentials and a legitimate (if time-limited) second factor token to log in with. WebAuthn prevents this by verifying that the site it's sending the secret to is the one that issued it in the first place - visit an attacker-controlled site and said attacker may get your username and password, but they won't be able to obtain a valid WebAuthn response.

But what if there was a mechanism for an attacker to direct a user to a legitimate login page, resulting in a happy WebAuthn flow, and obtain valid credentials for that user anyway? This seems like the lead-in to someone saying "The Aristocrats", but unfortunately it's (a) real, (b) RFC-defined, and (c) implemented in a whole bunch of places that handle sensitive credentials. The villain of this piece is RFC 8628, and while it exists for good reasons it can be used in a whole bunch of ways that have unfortunate security consequences.

What is the RFC 8628-defined Device Authorization Grant, and why does it exist? Imagine a device that you don't want to type a password into - either it has no input devices at all (eg, some IoT thing) or it's awkward to type a complicated password (eg, a TV with an on-screen keyboard). You want that device to be able to access resources on behalf of a user, so you want to ensure that that user authenticates the device. RFC 8628 describes an approach where the device requests the credentials, and then presents a code to the user (either on screen or over Bluetooth or something), and starts polling an endpoint for a result. The user visits a URL and types in that code (or is given a URL that has the code pre-populated) and is then guided through a standard auth process. The key distinction is that if the user authenticates correctly, the issued credentials are passed back to the device rather than the user - on successful auth, the endpoint the device is polling will return an oauth token.

But what happens if it's not a device that requests the credentials, but an attacker? What if said attacker obfuscates the URL in some way and tricks a user into clicking it? The user will be presented with their legitimate ID provider login screen, and if they're using a WebAuthn token for second factor it'll work correctly (because it's genuinely talking to the real ID provider!). The user will then typically be prompted to approve the request, but in every example I've seen the language used here is very generic and doesn't describe what's going on or ask the user. AWS simply says "An application or device requested authorization using your AWS sign-in" and has a big "Allow" button, giving the user no indication at all that hitting "Allow" may give a third party their credentials.

This isn't novel! Christoph Tafani-Dereeper has an excellent writeup on this topic from last year, which builds on Nestori Syynimaa's earlier work. But whenever I've talked about this, people seem surprised at the consequences. WebAuthn is supposed to protect against phishing attacks, but this approach subverts that protection by presenting the user with a legitimate login page and then handing their credentials to someone else.

RFC 8628 actually recognises this vector and presents a set of mitigations. Unfortunately nobody actually seems to implement these, and most of the mitigations are based around the idea that this flow will only be used for physical devices. Sadly, AWS uses this for initial authentication for the aws-cli tool, so there's no device in that scenario. Another mitigation is that there's a relatively short window where the code is valid, and so sending a link via email is likely to result in it expiring before the user clicks it. An attacker could avoid this by directing the user to a domain under their control that triggers the flow and then redirects the user to the login page, ensuring that the code is only generated after the user has clicked the link.

Can this be avoided? The best way to do so is to ensure that you don't support this token issuance flow anywhere, or if you do then ensure that any tokens issued that way are extremely narrowly scoped. Unfortunately if you're an AWS user, that's probably not viable - this flow is required for the cli tool to perform SSO login, and users are going to end up with broadly scoped tokens as a result. The logs are also not terribly useful.

The infuriating thing is that this isn't necessary for CLI tooling. The reason this approach is taken is that you need a way to get the token to a local process even if the user is doing authentication in a browser. This can be avoided by having the process listen on localhost, and then have the login flow redirect to localhost (including the token) on successful completion. In this scenario the attacker can't get access to the token without having access to the user's machine, and if they have that they probably have access to the token anyway.

There's no real moral here other than "Security is hard". Sorry.

Sam Hartman: Introducing Carthage

For the past four years, I ve been working on Carthage, a free-software Infrastructure as Code framework. We ve finally reached a point where it makes sense to talk about Carthage and what it can do. This is the first in a series of blog posts to introduce Carthage, discuss what it can do and show how it works. Why Another IAC Framework It seems everywhere you look, there are products designed to support the IAC pattern. On the simple side, you could check a Containerfile into Git. Products like Terraform and Vagrant allow you to template cloud infrastructure and VMs. There are more commercial offerings than I can keep up with. We were disappointed by what was out there when we started Carthage. Other products have improved, but for many of our applications we re happy with what Carthage can build. The biggest challenge we ran into is that products wanted us to specify things at the wrong level. For some of our cyber training work we wanted to say things like We want 3 blue teams, each with a couple defended networks, a red team, and some neutral infrastructure for red to exploit. Yet the tools we were trying to use wanted to lay things out at the individual machine/container level. We found ourselves contemplating writing a program to generate input for some other IAC tool. Things were worse for our internal testing. Sometimes we d be shipping hardware to a customer. But sometimes we d be virtualizing that build out in a lab. Sometimes we d be doing a mixture. So we wanted to completely separate the descriptions of machines, networks, and software from any of the information about whether that was realized on hardware, VMs, containers, or a mixture. Dimensional Breakdown In discussing Carthage with Enrico Zini, he pointed me at Cognitive Dimensions of notation as a way to think about how Carthage approaches the IAC problem. I m more interested in the idea of breaking down a design along the idea of dimensions that allow examining the design space than I am particular adherence to Green s original dimensions. Low Viscosity, High Abstraction Reuse One of the guiding principles is that we want to be able to reuse different components at different scales and in different environments. These include being able to do things like: Hidden Dependencies To accomplish these abstraction goals, dependencies need to be non-local. For example, a software role might need to integrate with a directory if a directory is present in the environment. When writing the role, no one is going to know which directory to use, nor whether a directory is present. Taking that as an explicit input into the role is error-prone when the role is combined into large abstract units (bigger roles or collections of machines). Instead it is better to have a non-local dependency, and to find the directory if it is available. We accomplish this using dependency injection. In addition to being non-local, dependencies are sometimes hidden. It is very easy to overwhelm our cognitive capacity with even a fairly simple IAC description. An effective notation allows us to focus on the parts that matter when working with a particular part of the description. I ve found hiding dependencies, especially indirect dependencies, to be essential in building complex descriptions. Obviously, tools are required for examining these dependencies as part of debugging. First Class Modeling Clearly one of the goals of IAC descriptions is to actually build and manage infrastructure. It turns out that there are all sorts of things you want to do with the description well before you instantiate the infrastructure. You might want to query the description to build network diagrams, understand interdependencies, or even build inventory/bill of materials. We often find ourselves building Ansible inventory, switch configurations, DNS zones, and all sorts of configuration artifacts. These artifacts may be installed into infrastructure that is instantiated by the description, but they may be consumed in other ways. Allowing the artifacts to be consumed externally means that you can avoid pre-commitment and focus on whatever part of the description you originally want to work on. You may use an existing network at first. Later the IAC description may replace that, or perhaps it never will. As a result, Carthage separates modeling from instantiation. The model can generally be built and queried without needing to interact with clouds, VMs, or containers. We ve actually found it useful to build Carthage layouts that cannot ever be fully instantiated, for example because they never specify details like whether a model should be instantiated on a container or VM, or what kind of technology will realize a modeled network. This allows developing roles before the machines that use them or focusing on how machines will interact and how the network will be laid out before the details of installing on specific hardware. The modeling separation is by far the difference I value most between Carthage and other systems. A Tool for Experts. In Neal Stephenson s essay In the Beginning Was the Command Line , Stephenson points out that the kind of tools experts need are not the same tools that beginners need. The illustration of why a beginner might not be satisfied with a Hole Hog drill caught my attention. Carthage is a tool for experts. Despite what cloud providers will tell you, IAC is not easy. Doubly so when you start making reusable components. Trying to hide that or focus on making things easy to get started can make it harder for experts to efficiently solve the problems they are facing. When we have faced trade offs between making Carthage easy to pick up and making it powerful for expert users, we have chosen to support the experts. That said, Carthage today is harder to pick up than it needs to be. It s a relatively new project with few external users as of this time. Our documentation and examples need improvement, just like every project at this level of maturity. Similarly, as the set of things people try to do expand, we will doubtless run into bugs that our current test cases don t cover. So Carthage absolutely will get easier to learn and use than it is today. Also, we ve already had success building beginner-focused applications on top of Carthage. For our cyber training, we built web applications on top of Carthage that made rebuilding and exploring infrastructure easy. We ve had success using relatively understood tools like Ansible as integration and customization points for Carthage layouts. But in all these cases, when the core layout had significant reusable components and significant complexity in the networking, only an IAC expert was going to be able to maintain and develop that layout. What Carthage can do. Carthage has a number of capabilities today. One of Carthage s strengths is its extensible design. Abstract interfaces make it easy to add new virtualization platforms, cloud services, and support for various ways of managing real hardware. This approach has been validated by incrementally adding support for virtualization architectures and cloud services. As development has progressed, adding new integrations continues to get faster because we are able to reuse existing infrastructure. Today, Carthage can model: Carthage has excellent facilities for dealing with images on which VMs and Containers can be based, although it does have a bit of a Debian/Ubuntu bias in how it thinks about images: When instantiating infrastructure, Carthage can work with: We have also looked at Oracle Cloud and I believe Openstack, although that code is not merged. Future posts will talk about core Carthage concepts and how to use Carthage to build infrastructure.

Antoine Beaupr : Wayland: i3 to Sway migration

I started migrating my graphical workstations to Wayland, specifically migrating from i3 to Sway. This is mostly to address serious graphics bugs in the latest Framwork laptop, but also something I felt was inevitable. The current status is that I've been able to convert my i3 configuration to Sway, and adapt my systemd startup sequence to the new environment. Screen sharing only works with Pipewire, so I also did that migration, which basically requires an upgrade to Debian bookworm to get a nice enough Pipewire release. I'm testing Wayland on my laptop, but I'm not using it as a daily driver because I first need to upgrade to Debian bookworm on my main workstation. Most irritants have been solved one way or the other. My main problem with Wayland right now is that I spent a frigging week doing the conversion: it's exciting and new, but it basically sucked the life out of all my other projects and it's distracting, and I want it to stop. The rest of this page documents why I made the switch, how it happened, and what's left to do. Hopefully it will keep you from spending as much time as I did in fixing this. TL;DR: Wayland is mostly ready. Main blockers you might find are that you need to do manual configurations, DisplayLink (multiple monitors on a single cable) doesn't work in Sway, HDR and color management are still in development. I had to install the following packages: 
apt install \
    brightnessctl \
    foot \
    gammastep \
    gdm3 \
    grim slurp \
    pipewire-pulse \
    sway \
    swayidle \
    swaylock \
    wdisplays \
    wev \
    wireplumber \
    wlr-randr \
    xdg-desktop-portal-wlr
And did some of tweaks in my $HOME, mostly dealing with my esoteric systemd startup sequence, which you won't have to deal with if you are not a fan.

Why switch? I originally held back from migrating to Wayland: it seemed like a complicated endeavor hardly worth the cost. It also didn't seem actually ready. But after reading this blurb on LWN, I decided to at least document the situation here. The actual quote that convinced me it might be worth it was:
It s amazing. I have never experienced gaming on Linux that looked this smooth in my life.
... I'm not a gamer, but I do care about latency. The longer version is worth a read as well. The point here is not to bash one side or the other, or even do a thorough comparison. I start with the premise that Xorg is likely going away in the future and that I will need to adapt some day. In fact, the last major Xorg release (21.1, October 2021) is rumored to be the last ("just like the previous release...", that said, minor releases are still coming out, e.g. 21.1.4). Indeed, it seems even core Xorg people have moved on to developing Wayland, or at least Xwayland, which was spun off it its own source tree. X, or at least Xorg, in in maintenance mode and has been for years. Granted, the X Window System is getting close to forty years old at this point: it got us amazingly far for something that was designed around the time the first graphical interface. Since Mac and (especially?) Windows released theirs, they have rebuilt their graphical backends numerous times, but UNIX derivatives have stuck on Xorg this entire time, which is a testament to the design and reliability of X. (Or our incapacity at developing meaningful architectural change across the entire ecosystem, take your pick I guess.) What pushed me over the edge is that I had some pretty bad driver crashes with Xorg while screen sharing under Firefox, in Debian bookworm (around November 2022). The symptom would be that the UI would completely crash, reverting to a text-only console, while Firefox would keep running, audio and everything still working. People could still see my screen, but I couldn't, of course, let alone interact with it. All processes still running, including Xorg. (And no, sorry, I haven't reported that bug, maybe I should have, and it's actually possible it comes up again in Wayland, of course. But at first, screen sharing didn't work of course, so it's coming a much further way. After making screen sharing work, though, the bug didn't occur again, so I consider this a Xorg-specific problem until further notice.) There were also frustrating glitches in the UI, in general. I actually had to setup a compositor alongside i3 to make things bearable at all. Video playback in a window was laggy, sluggish, and out of sync. Wayland fixed all of this.

Wayland equivalents This section documents each tool I have picked as an alternative to the current Xorg tool I am using for the task at hand. It also touches on other alternatives and how the tool was configured. Note that this list is based on the series of tools I use in desktop. TODO: update desktop with the following when done, possibly moving old configs to a ?xorg archive.

Window manager: i3 sway This seems like kind of a no-brainer. Sway is around, it's feature-complete, and it's in Debian. I'm a bit worried about the "Drew DeVault community", to be honest. There's a certain aggressiveness in the community I don't like so much; at least an open hostility towards more modern UNIX tools like containers and systemd that make it hard to do my work while interacting with that community. I'm also concern about the lack of unit tests and user manual for Sway. The i3 window manager has been designed by a fellow (ex-)Debian developer I have a lot of respect for (Michael Stapelberg), partly because of i3 itself, but also working with him on other projects. Beyond the characters, i3 has a user guide, a code of conduct, and lots more documentation. It has a test suite. Sway has... manual pages, with the homepage just telling users to use man -k sway to find what they need. I don't think we need that kind of elitism in our communities, to put this bluntly. But let's put that aside: Sway is still a no-brainer. It's the easiest thing to migrate to, because it's mostly compatible with i3. I had to immediately fix those resources to get a minimal session going:
i3 Sway note
set_from_resources set no support for X resources, naturally
new_window pixel 1 default_border pixel 1 actually supported in i3 as well
That's it. All of the other changes I had to do (and there were actually a lot) were all Wayland-specific changes, not Sway-specific changes. For example, use brightnessctl instead of xbacklight to change the backlight levels. See a copy of my full sway/config for details. Other options include:
  • dwl: tiling, minimalist, dwm for Wayland, not in Debian
  • Hyprland: tiling, fancy animations, not in Debian
  • Qtile: tiling, extensible, in Python, not in Debian (1015267)
  • river: Zig, stackable, tagging, not in Debian (1006593)
  • velox: inspired by xmonad and dwm, not in Debian
  • vivarium: inspired by xmonad, not in Debian

Status bar: py3status waybar I have invested quite a bit of effort in setting up my status bar with py3status. It supports Sway directly, and did not actually require any change when migrating to Wayland. Unfortunately, I had trouble making nm-applet work. Based on this nm-applet.service, I found that you need to pass --indicator for it to show up at all. In theory, tray icon support was merged in 1.5, but in practice there are still several limitations, like icons not clickable. Also, on startup, nm-applet --indicator triggers this error in the Sway logs: 
nov 11 22:34:12 angela sway[298938]: 00:49:42.325 [INFO] [swaybar/tray/host.c:24] Registering Status Notifier Item ':1.47/org/ayatana/NotificationItem/nm_applet'

... but that seems innocuous. The tray icon displays but is not clickable. Note that there is currently (November 2022) a pull request to hook up a "Tray D-Bus Menu" which, according to Reddit might fix this, or at least be somewhat relevant. If you don't see the icon, check the bar.tray_output property in the Sway config, try: tray_output *. The non-working tray was the biggest irritant in my migration. I have used nmtui to connect to new Wifi hotspots or change connection settings, but that doesn't support actions like "turn off WiFi". I eventually fixed this by switching from py3status to waybar, which was another yak horde shaving session, but ultimately, it worked.

Web browser: Firefox Firefox has had support for Wayland for a while now, with the team enabling it by default in nightlies around January 2022. It's actually not easy to figure out the state of the port, the meta bug report is still open and it's huge: it currently (Sept 2022) depends on 76 open bugs, it was opened twelve (2010) years ago, and it's still getting daily updates (mostly linking to other tickets). Firefox 106 presumably shipped with "Better screen sharing for Windows and Linux Wayland users", but I couldn't quite figure out what those were. TL;DR: echo MOZ_ENABLE_WAYLAND=1 >> ~/.config/environment.d/firefox.conf && apt install xdg-desktop-portal-wlr

How to enable it Firefox depends on this silly variable to start correctly under Wayland (otherwise it starts inside Xwayland and looks fuzzy and fails to screen share): 
MOZ_ENABLE_WAYLAND=1 firefox
To make the change permanent, many recipes recommend adding this to an environment startup script: 
if [ "$XDG_SESSION_TYPE" == "wayland" ]; then
    export MOZ_ENABLE_WAYLAND=1
fi
At least that's the theory. In practice, Sway doesn't actually run any startup shell script, so that can't possibly work. Furthermore, XDG_SESSION_TYPE is not actually set when starting Sway from gdm3 which I find really confusing, and I'm not the only one. So the above trick doesn't actually work, even if the environment (XDG_SESSION_TYPE) is set correctly, because we don't have conditionals in environment.d(5). (Note that systemd.environment-generator(7) do support running arbitrary commands to generate environment, but for some some do not support user-specific configuration files... Even then it may be a solution to have a conditional MOZ_ENABLE_WAYLAND environment, but I'm not sure it would work because ordering between those two isn't clear: maybe the XDG_SESSION_TYPE wouldn't be set just yet...) At first, I made this ridiculous script to workaround those issues. Really, it seems to me Firefox should just parse the XDG_SESSION_TYPE variable here... but then I realized that Firefox works fine in Xorg when the MOZ_ENABLE_WAYLAND is set. So now I just set that variable in environment.d and It Just Works : 
MOZ_ENABLE_WAYLAND=1

Screen sharing Out of the box, screen sharing doesn't work until you install xdg-desktop-portal-wlr or similar (e.g. xdg-desktop-portal-gnome on GNOME). I had to reboot for the change to take effect. Without those tools, it shows the usual permission prompt with "Use operating system settings" as the only choice, but when we accept... nothing happens. After installing the portals, it actualyl works, and works well! This was tested in Debian bookworm/testing with Firefox ESR 102 and Firefox 106. Major caveat: we can only share a full screen, we can't currently share just a window. The major upside to that is that, by default, it streams only one output which is actually what I want most of the time! See the screencast compatibility for more information on what is supposed to work. This is actually a huge improvement over the situation in Xorg, where Firefox can only share a window or all monitors, which led me to use Chromium a lot for video-conferencing. With this change, in other words, I will not need Chromium for anything anymore, whoohoo! If slurp, wofi, or bemenu are installed, one of them will be used to pick the monitor to share, which effectively acts as some minimal security measure. See xdg-desktop-portal-wlr(1) for how to configure that.

Side note: Chrome fails to share a full screen I was still using Google Chrome (or, more accurately, Debian's Chromium package) for some videoconferencing. It's mainly because Chromium was the only browser which will allow me to share only one of my two monitors, which is extremely useful. To start chrome with the Wayland backend, you need to use: 
chromium  -enable-features=UseOzonePlatform -ozone-platform=wayland
If it shows an ugly gray border, check the Use system title bar and borders setting. It can do some screensharing. Sharing a window and a tab seems to work, but sharing a full screen doesn't: it's all black. Maybe not ready for prime time. And since Firefox can do what I need under Wayland now, I will not need to fight with Chromium to work under Wayland: 
apt purge chromium
Note that a similar fix was necessary for Signal Desktop, see this commit. Basically you need to figure out a way to pass those same flags to signal: 
--enable-features=WaylandWindowDecorations --ozone-platform-hint=auto

Email: notmuch See Emacs, below.

File manager: thunar Unchanged.

News: feed2exec, gnus See Email, above, or Emacs in Editor, below.

Editor: Emacs okay-ish Emacs is being actively ported to Wayland. According to this LWN article, the first (partial, to Cairo) port was done in 2014 and a working port (to GTK3) was completed in 2021, but wasn't merged until late 2021. That is: after Emacs 28 was released (April 2022). So we'll probably need to wait for Emacs 29 to have native Wayland support in Emacs, which, in turn, is unlikely to arrive in time for the Debian bookworm freeze. There are, however, unofficial builds for both Emacs 28 and 29 provided by spwhitton which may provide native Wayland support. I tested the snapshot packages and they do not quite work well enough. First off, they completely take over the builtin Emacs they hijack the $PATH in /etc! and certain things are simply not working in my setup. For example, this hook never gets ran on startup: 
(add-hook 'after-init-hook 'server-start t)
Still, like many X11 applications, Emacs mostly works fine under Xwayland. The clipboard works as expected, for example. Scaling is a bit of an issue: fonts look fuzzy. I have heard anecdotal evidence of hard lockups with Emacs running under Xwayland as well, but haven't experienced any problem so far. I did experience a Wayland crash with the snapshot version however. TODO: look again at Wayland in Emacs 29.

Backups: borg Mostly irrelevant, as I do not use a GUI.

Color theme: srcery, redshift gammastep I am keeping Srcery as a color theme, in general. Redshift is another story: it has no support for Wayland out of the box, but it's apparently possible to apply a hack on the TTY before starting Wayland, with: 
redshift -m drm -PO 3000
This tip is from the arch wiki which also has other suggestions for Wayland-based alternatives. Both KDE and GNOME have their own "red shifters", and for wlroots-based compositors, they (currently, Sept. 2022) list the following alternatives: I configured gammastep with a simple gammastep.service file associated with the sway-session.target.

Possible alternatives:

Terminal: xterm foot One of the biggest question mark in this transition was what to do about Xterm. After writing two articles about terminal emulators as a professional journalist, decades of working on the terminal, and probably using dozens of different terminal emulators, I'm still not happy with any of them. This is such a big topic that I actually have an entire blog post specifically about this. For starters, using xterm under Xwayland works well enough, although the font scaling makes things look a bit too fuzzy. I have also tried foot: it ... just works! Fonts are much crisper than Xterm and Emacs. URLs are not clickable but the URL selector (control-shift-u) is just plain awesome (think "vimperator" for the terminal). There's cool hack to jump between prompts. Copy-paste works. True colors work. The word-wrapping is excellent: it doesn't lose one byte. Emojis are nicely sized and colored. Font resize works. There's even scroll back search (control-shift-r). Foot went from a question mark to being a reason to switch to Wayland, just for this little goodie, which says a lot about the quality of that software. The selection clicks are a not quite what I would expect though. In rxvt and others, you have the following patterns:
  • single click: reset selection, or drag to select
  • double: select word
  • triple: select quotes or line
  • quadruple: select line
I particularly find the "select quotes" bit useful. It seems like foot just supports double and triple clicks, with word and line selected. You can select a rectangle with control,. It correctly extends the selection word-wise with right click if double-click was first used. One major problem with Foot is that it's a new terminal, with its own termcap entry. Support for foot was added to ncurses in the 20210731 release, which was shipped after the current Debian stable release (Debian bullseye, which ships 6.2+20201114-2). A workaround for this problem is to install the foot-terminfo package on the remote host, which is available in Debian stable. This should eventually resolve itself, as Debian bookworm has a newer version. Note that some corrections were also shipped in the 20211113 release, but that is also shipped in Debian bookworm. That said, I am almost certain I will have to revert back to xterm under Xwayland at some point in the future. Back when I was using GNOME Terminal, it would mostly work for everything until I had to use the serial console on a (HP ProCurve) network switch, which have a fancy TUI that was basically unusable there. I fully expect such problems with foot, or any other terminal than xterm, for that matter. The foot wiki has good troubleshooting instructions as well. Update: I did find one tiny thing to improve with foot, and it's the default logging level which I found pretty verbose. After discussing it with the maintainer on IRC, I submitted this patch to tweak it, which I described like this on Mastodon:

It's Friday.

Launcher: rofi rofi?? rofi does not support Wayland. There was a rather disgraceful battle in the pull request that led to the creation of a fork (lbonn/rofi), so it's unclear how that will turn out. Given how relatively trivial problem space is, there is of course a profusion of options:
Tool In Debian Notes
alfred yes general launcher/assistant tool
bemenu yes, bookworm+ inspired by dmenu
cerebro no Javascript ... uh... thing
dmenu-wl no fork of dmenu, straight port to Wayland
Fuzzel ITP 982140 dmenu/drun replacement, app icon overlay
gmenu no drun replacement, with app icons
kickoff no dmenu/run replacement, fuzzy search, "snappy", history, copy-paste, Rust
krunner yes KDE's runner
mauncher no dmenu/drun replacement, math
nwg-launchers no dmenu/drun replacement, JSON config, app icons, nwg-shell project
Onagre no rofi/alfred inspired, multiple plugins, Rust
menu no dmenu/drun rewrite
Rofi (lbonn's fork) no see above
sirula no .desktop based app launcher
Ulauncher ITP 949358 generic launcher like Onagre/rofi/alfred, might be overkill
tofi yes, bookworm+ dmenu/drun replacement, C
wmenu no fork of dmenu-wl, but mostly a rewrite
Wofi yes dmenu/drun replacement, not actively maintained
yofi no dmenu/drun replacement, Rust
The above list comes partly from https://arewewaylandyet.com/ and awesome-wayland. It is likely incomplete. I have read some good things about bemenu, fuzzel, and wofi. A particularly tricky option is that my rofi password management depends on xdotool for some operations. At first, I thought this was just going to be (thankfully?) impossible, because we actually like the idea that one app cannot send keystrokes to another. But it seems there are actually alternatives to this, like wtype or ydotool, the latter which requires root access. wl-ime-type does that through the input-method-unstable-v2 protocol (sample emoji picker, but is not packaged in Debian. As it turns out, wtype just works as expected, and fixing this was basically a two-line patch. Another alternative, not in Debian, is wofi-pass. The other problem is that I actually heavily modified rofi. I use "modis" which are not actually implemented in wofi or tofi, so I'm left with reinventing those wheels from scratch or using the rofi + wayland fork... It's really too bad that fork isn't being reintegrated... For now, I'm actually still using rofi under Xwayland. The main downside is that fonts are fuzzy, but it otherwise just works. Note that wlogout could be a partial replacement (just for the "power menu").

Image viewers: geeqie ? I'm not very happy with geeqie in the first place, and I suspect the Wayland switch will just make add impossible things on top of the things I already find irritating (Geeqie doesn't support copy-pasting images). In practice, Geeqie doesn't seem to work so well under Wayland. The fonts are fuzzy and the thumbnail preview just doesn't work anymore (filed as Debian bug 1024092). It seems it also has problems with scaling. Alternatives: See also this list and that list for other list of image viewers, not necessarily ported to Wayland. TODO: pick an alternative to geeqie, nomacs would be gorgeous if it wouldn't be basically abandoned upstream (no release since 2020), has an unpatched CVE-2020-23884 since July 2020, does bad vendoring, and is in bad shape in Debian (4 minor releases behind). So for now I'm still grumpily using Geeqie.

Media player: mpv, gmpc / sublime This is basically unchanged. mpv seems to work fine under Wayland, better than Xorg on my new laptop (as mentioned in the introduction), and that before the version which improves Wayland support significantly, by bringing native Pipewire support and DMA-BUF support. gmpc is more of a problem, mainly because it is abandoned. See 2022-08-22-gmpc-alternatives for the full discussion, one of the alternatives there will likely support Wayland. Finally, I might just switch to sublime-music instead... In any case, not many changes here, thankfully.

Screensaver: xsecurelock swaylock I was previously using xss-lock and xsecurelock as a screensaver, with xscreensaver "hacks" as a backend for xsecurelock. The basic screensaver in Sway seems to be built with swayidle and swaylock. It's interesting because it's the same "split" design as xss-lock and xsecurelock. That, unfortunately, does not include the fancy "hacks" provided by xscreensaver, and that is unlikely to be implemented upstream. Other alternatives include gtklock and waylock (zig), which do not solve that problem either. It looks like swaylock-plugin, a swaylock fork, which at least attempts to solve this problem, although not directly using the real xscreensaver hacks. swaylock-effects is another attempt at this, but it only adds more effects, it doesn't delegate the image display. Other than that, maybe it's time to just let go of those funky animations and just let swaylock do it's thing, which is display a static image or just a black screen, which is fine by me. In the end, I am just using swayidle with a configuration based on the systemd integration wiki page but with additional tweaks from this service, see the resulting swayidle.service file. Interestingly, damjan also has a service for swaylock itself, although it's not clear to me what its purpose is...

Screenshot: maim grim, pubpaste I'm a heavy user of maim (and a package uploader in Debian). It looks like the direct replacement to maim (and slop) is grim (and slurp). There's also swappy which goes on top of grim and allows preview/edit of the resulting image, nice touch (not in Debian though). See also awesome-wayland screenshots for other alternatives: there are many, including X11 tools like Flameshot that also support Wayland. One key problem here was that I have my own screenshot / pastebin software which will needed an update for Wayland as well. That, thankfully, meant actually cleaning up a lot of horrible code that involved calling xterm and xmessage for user interaction. Now, pubpaste uses GTK for prompts and looks much better. (And before anyone freaks out, I already had to use GTK for proper clipboard support, so this isn't much of a stretch...)

Screen recorder: simplescreenrecorder wf-recorder In Xorg, I have used both peek or simplescreenrecorder for screen recordings. The former will work in Wayland, but has no sound support. The latter has a fork with Wayland support but it is limited and buggy ("doesn't support recording area selection and has issues with multiple screens"). It looks like wf-recorder will just do everything correctly out of the box, including audio support (with --audio, duh). It's also packaged in Debian. One has to wonder how this works while keeping the "between app security" that Wayland promises, however... Would installing such a program make my system less secure? Many other options are available, see the awesome Wayland screencasting list.

RSI: workrave nothing? Workrave has no support for Wayland. activity watch is a time tracker alternative, but is not a RSI watcher. KDE has rsiwatcher, but that's a bit too much on the heavy side for my taste. SafeEyes looks like an alternative at first, but it has many issues under Wayland (escape doesn't work, idle doesn't work, it just doesn't work really). timekpr-next could be an alternative as well, and has support for Wayland. I am also considering just abandoning workrave, even if I stick with Xorg, because it apparently introduces significant latency in the input pipeline. And besides, I've developed a pretty unhealthy alert fatigue with Workrave. I have used the program for so long that my fingers know exactly where to click to dismiss those warnings very effectively. It makes my work just more irritating, and doesn't fix the fundamental problem I have with computers.

Other apps This is a constantly changing list, of course. There's a bit of a "death by a thousand cuts" in migrating to Wayland because you realize how many things you were using are tightly bound to X.
  • .Xresources - just say goodbye to that old resource system, it was used, in my case, only for rofi, xterm, and ... Xboard!?
  • keyboard layout switcher: built-in to Sway since 2017 (PR 1505, 1.5rc2+), requires a small configuration change, see this answer as well, looks something like this command: 
     swaymsg input 0:0:X11_keyboard xkb_layout de
    or using this config: 
     input *  
     xkb_layout "ca,us"
     xkb_options "grp:sclk_toggle"
    That works refreshingly well, even better than in Xorg, I must say. swaykbdd is an alternative that supports per-window layouts (in Debian).
  • wallpaper: currently using feh, will need a replacement, TODO: figure out something that does, like feh, a random shuffle. swaybg just loads a single image, duh. oguri might be a solution, but unmaintained, used here, not in Debian. wallutils is another option, also not in Debian. For now I just don't have a wallpaper, the background is a solid gray, which is better than Xorg's default (which is whatever crap was left around a buffer by the previous collection of programs, basically)
  • notifications: currently using dunst in some places, which works well in both Xorg and Wayland, not a blocker, salut a possible alternative (not in Debian), damjan uses mako. TODO: install dunst everywhere
  • notification area: I had trouble making nm-applet work. based on this nm-applet.service, I found that you need to pass --indicator. In theory, tray icon support was merged in 1.5, but in practice there are still several limitations, like icons not clickable. On startup, nm-applet --indicator triggers this error in the Sway logs: 
     nov 11 22:34:12 angela sway[298938]: 00:49:42.325 [INFO] [swaybar/tray/host.c:24] Registering Status Notifier Item ':1.47/org/ayatana/NotificationItem/nm_applet'

    ... but it seems innocuous. The tray icon displays but, as stated above, is not clickable. If you don't see the icon, check the bar.tray_output property in the Sway config, try: tray_output *. Note that there is currently (November 2022) a pull request to hook up a "Tray D-Bus Menu" which, according to Reddit might fix this, or at least be somewhat relevant. This was the biggest irritant in my migration. I have used nmtui to connect to new Wifi hotspots or change connection settings, but that doesn't support actions like "turn off WiFi". I eventually fixed this by switching from py3status to waybar.
  • window switcher: in i3 I was using this bespoke i3-focus script, which doesn't work under Sway, swayr an option, not in Debian. So I put together this other bespoke hack from multiple sources, which works.
  • PDF viewer: currently using atril (which supports Wayland), could also just switch to zatura/mupdf permanently, see also calibre for a discussion on document viewers
See also this list of useful addons and this other list for other app alternatives.

More X11 / Wayland equivalents For all the tools above, it's not exactly clear what options exist in Wayland, or when they do, which one should be used. But for some basic tools, it seems the options are actually quite clear. If that's the case, they should be listed here:
X11 Wayland In Debian
arandr wdisplays yes
autorandr kanshi yes
xdotool wtype yes
xev wev yes
xlsclients swaymsg -t get_tree yes
xrandr wlr-randr yes
lswt is a more direct replacement for xlsclients but is not packaged in Debian. See also: Note that arandr and autorandr are not directly part of X. arewewaylandyet.com refers to a few alternatives. We suggest wdisplays and kanshi above (see also this service file) but wallutils can also do the autorandr stuff, apparently, and nwg-displays can do the arandr part. Neither are packaged in Debian yet. So I have tried wdisplays and it Just Works, and well. The UI even looks better and more usable than arandr, so another clean win from Wayland here. TODO: test kanshi as a autorandr replacement

Other issues

systemd integration I've had trouble getting session startup to work. This is partly because I had a kind of funky system to start my session in the first place. I used to have my whole session started from .xsession like this: 
#!/bin/sh
. ~/.shenv
systemctl --user import-environment
exec systemctl --user start --wait xsession.target
But obviously, the xsession.target is not started by the Sway session. It seems to just start a default.target, which is really not what we want because we want to associate the services directly with the graphical-session.target, so that they don't start when logging in over (say) SSH. damjan on #debian-systemd showed me his sway-setup which features systemd integration. It involves starting a different session in a completely new .desktop file. That work was submitted upstream but refused on the grounds that "I'd rather not give a preference to any particular init system." Another PR was abandoned because "restarting sway does not makes sense: that kills everything". The work was therefore moved to the wiki. So. Not a great situation. The upstream wiki systemd integration suggests starting the systemd target from within Sway, which has all sorts of problems:
  • you don't get Sway logs anywhere
  • control groups are all messed up
I have done a lot of work trying to figure this out, but I remember that starting systemd from Sway didn't actually work for me: my previously configured systemd units didn't correctly start, and especially not with the right $PATH and environment. So I went down that rabbit hole and managed to correctly configure Sway to be started from the systemd --user session. I have partly followed the wiki but also picked ideas from damjan's sway-setup and xdbob's sway-services. Another option is uwsm (not in Debian). This is the config I have in .config/systemd/user/: I have also configured those services, but that's somewhat optional: You will also need at least part of my sway/config, which sends the systemd notification (because, no, Sway doesn't support any sort of readiness notification, that would be too easy). And you might like to see my swayidle-config while you're there. Finally, you need to hook this up somehow to the login manager. This is typically done with a desktop file, so drop sway-session.desktop in /usr/share/wayland-sessions and sway-user-service somewhere in your $PATH (typically /usr/bin/sway-user-service). The session then looks something like this:

I think that's pretty neat.

Environment propagation At first, my terminals and rofi didn't have the right $PATH, which broke a lot of my workflow. It's hard to tell exactly how Wayland gets started or where to inject environment. This discussion suggests a few alternatives and this Debian bug report discusses this issue as well. I eventually picked environment.d(5) since I already manage my user session with systemd, and it fixes a bunch of other problems. I used to have a .shenv that I had to manually source everywhere. The only problem with that approach is that it doesn't support conditionals, but that's something that's rarely needed.

Pipewire This is a whole topic onto itself, but migrating to Wayland also involves using Pipewire if you want screen sharing to work. You can actually keep using Pulseaudio for audio, that said, but that migration is actually something I've wanted to do anyways: Pipewire's design seems much better than Pulseaudio, as it folds in JACK features which allows for pretty neat tricks. (Which I should probably show in a separate post, because this one is getting rather long.) I first tried this migration in Debian bullseye, and it didn't work very well. Ardour would fail to export tracks and I would get into weird situations where streams would just drop mid-way. A particularly funny incident is when I was in a meeting and I couldn't hear my colleagues speak anymore (but they could) and I went on blabbering on my own for a solid 5 minutes until I realized what was going on. By then, people had tried numerous ways of letting me know that something was off, including (apparently) coughing, saying "hello?", chat messages, IRC, and so on, until they just gave up and left. I suspect that was also a Pipewire bug, but it could also have been that I muted the tab by error, as I recently learned that clicking on the little tiny speaker icon on a tab mutes that tab. Since the tab itself can get pretty small when you have lots of them, it's actually quite frequently that I mistakenly mute tabs. Anyways. Point is: I already knew how to make the migration, and I had already documented how to make the change in Puppet. It's basically: 
apt install pipewire pipewire-audio-client-libraries pipewire-pulse wireplumber
Then, as a regular user: 
systemctl --user daemon-reload
systemctl --user --now disable pulseaudio.service pulseaudio.socket
systemctl --user --now enable pipewire pipewire-pulse
systemctl --user mask pulseaudio
An optional (but key, IMHO) configuration you should also make is to "switch on connect", which will make your Bluetooth or USB headset automatically be the default route for audio, when connected. In ~/.config/pipewire/pipewire-pulse.conf.d/autoconnect.conf: 
context.exec = [
      path = "pactl"        args = "load-module module-always-sink"  
      path = "pactl"        args = "load-module module-switch-on-connect"  
    #  path = "/usr/bin/sh"  args = "~/.config/pipewire/default.pw"  
]
See the excellent as usual Arch wiki page about Pipewire for that trick and more information about Pipewire. Note that you must not put the file in ~/.config/pipewire/pipewire.conf (or pipewire-pulse.conf, maybe) directly, as that will break your setup. If you want to add to that file, first copy the template from /usr/share/pipewire/pipewire-pulse.conf first. So far I'm happy with Pipewire in bookworm, but I've heard mixed reports from it. I have high hopes it will become the standard media server for Linux in the coming months or years, which is great because I've been (rather boldly, I admit) on the record saying I don't like PulseAudio. Rereading this now, I feel it might have been a little unfair, as "over-engineered and tries to do too many things at once" applies probably even more to Pipewire than PulseAudio (since it also handles video dispatching). That said, I think Pipewire took the right approach by implementing existing interfaces like Pulseaudio and JACK. That way we're not adding a third (or fourth?) way of doing audio in Linux; we're just making the server better.

Keypress drops Sometimes I lose keyboard presses. This correlates with the following warning from Sway: 
d c 06 10:36:31 curie sway[343384]: 23:32:14.034 [ERROR] [wlr] [libinput] event5  - SONiX USB Keyboard: client bug: event processing lagging behind by 37ms, your system is too slow
... and corresponds to an open bug report in Sway. It seems the "system is too slow" should really be "your compositor is too slow" which seems to be the case here on this older system (curie). It doesn't happen often, but it does happen, particularly when a bunch of busy processes start in parallel (in my case: a linter running inside a container and notmuch new). The proposed fix for this in Sway is to gain real time privileges and add the CAP_SYS_NICE capability to the binary. We'll see how that goes in Debian once 1.8 gets released and shipped.

Improvements over i3

Tiling improvements There's a lot of improvements Sway could bring over using plain i3. There are pretty neat auto-tilers that could replicate the configurations I used to have in Xmonad or Awesome, see:

Display latency tweaks TODO: You can tweak the display latency in wlroots compositors with the max_render_time parameter, possibly getting lower latency than X11 in the end.

Sound/brightness changes notifications TODO: Avizo can display a pop-up to give feedback on volume and brightness changes. Not in Debian. Other alternatives include SwayOSD and sway-nc, also not in Debian.

Debugging tricks The xeyes (in the x11-apps package) will run in Wayland, and can actually be used to easily see if a given window is also in Wayland. If the "eyes" follow the cursor, the app is actually running in xwayland, so not natively in Wayland. Another way to see what is using Wayland in Sway is with the command: 
swaymsg -t get_tree

Other documentation

Conclusion In general, this took me a long time, but it mostly works. The tray icon situation is pretty frustrating, but there's a workaround and I have high hopes it will eventually fix itself. I'm also actually worried about the DisplayLink support because I eventually want to be using this, but hopefully that's another thing that will hopefully fix itself before I need it.

A word on the security model I'm kind of worried about all the hacks that have been added to Wayland just to make things work. Pretty much everywhere we need to, we punched a hole in the security model: Wikipedia describes the security properties of Wayland as it "isolates the input and output of every window, achieving confidentiality, integrity and availability for both." I'm not sure those are actually realized in the actual implementation, because of all those holes punched in the design, at least in Sway. For example, apparently the GNOME compositor doesn't have the virtual-keyboard protocol, but they do have (another?!) text input protocol. Wayland does offer a better basis to implement such a system, however. It feels like the Linux applications security model lacks critical decision points in the UI, like the user approving "yes, this application can share my screen now". Applications themselves might have some of those prompts, but it's not mandatory, and that is worrisome.

Reproducible Builds: Reproducible Builds in October 2022

Welcome to the Reproducible Builds report for October 2022! In these reports we attempt to outline the most important things that we have been up to over the past month. As ever, if you are interested in contributing to the project, please visit our Contribute page on our website.

Our in-person summit this year was held in the past few days in Venice, Italy. Activity and news from the summit will therefore be covered in next month s report!
A new article related to reproducible builds was recently published in the 2023 IEEE Symposium on Security and Privacy. Titled Taxonomy of Attacks on Open-Source Software Supply Chains and authored by Piergiorgio Ladisa, Henrik Plate, Matias Martinez and Olivier Barais, their paper:
[ ] proposes a general taxonomy for attacks on opensource supply chains, independent of specific programming languages or ecosystems, and covering all supply chain stages from code contributions to package distribution.
Taking the form of an attack tree, the paper covers 107 unique vectors linked to 94 real world supply-chain incidents which is then mapped to 33 mitigating safeguards including, of course, reproducible builds:
Reproducible Builds received a very high utility rating (5) from 10 participants (58.8%), but also a high-cost rating (4 or 5) from 12 (70.6%). One expert commented that a reproducible build like used by Solarwinds now, is a good measure against tampering with a single build system and another claimed this is going to be the single, biggest barrier .
It was noticed this month that Solarwinds published a whitepaper back in December 2021 in order to:
[ ] illustrate a concerning new reality for the software industry and illuminates the increasingly sophisticated threats made by outside nation-states to the supply chains and infrastructure on which we all rely.
The 12-month anniversary of the 2020 Solarwinds attack (which SolarWinds Worldwide LLC itself calls the SUNBURST attack) was, of course, the likely impetus for publication.
Whilst collaborating on making the Cyrus IMAP server reproducible, Ellie Timoney asked why the Reproducible Builds testing framework uses two remarkably distinctive build paths when attempting to flush out builds that vary on the absolute system path in which they were built. In the case of the Cyrus IMAP server, these happened to be: Asked why they vary in three different ways, Chris Lamb listed in detail the motivation behind to each difference.
On our mailing list this month:
The Reproducible Builds project is delighted to welcome openEuler to the Involved projects page [ ]. openEuler is Linux distribution developed by Huawei, a counterpart to it s more commercially-oriented EulerOS.

Debian Colin Watson wrote about his experience towards making the databases generated by the man-db UNIX manual page indexing tool:
One of the people working on [reproducible builds] noticed that man-db s database files were an obstacle to [reproducibility]: in particular, the exact contents of the database seemed to depend on the order in which files were scanned when building it. The reporter proposed solving this by processing files in sorted order, but I wasn t keen on that approach: firstly because it would mean we could no longer process files in an order that makes it more efficient to read them all from disk (still valuable on rotational disks), but mostly because the differences seemed to point to other bugs.
Colin goes on to describe his approach to solving the problem, including fixing various fits of internal caching, and he ends his post with None of this is particularly glamorous work, but it paid off .
Vagrant Cascadian announced on our mailing list another online sprint to help clear the huge backlog of reproducible builds patches submitted by performing NMUs (Non-Maintainer Uploads). The first such sprint took place on September 22nd, but another was held on October 6th, and another small one on October 20th. This resulted in the following progress:
41 reviews of Debian packages were added, 62 were updated and 12 were removed this month adding to our knowledge about identified issues. A number of issue types were updated too. [1][ ]
Lastly, Luca Boccassi submitted a patch to debhelper, a set of tools used in the packaging of the majority of Debian packages. The patch addressed an issue in the dh_installsysusers utility so that the postinst post-installation script that debhelper generates the same data regardless of the underlying filesystem ordering.

Other distributions F-Droid is a community-run app store that provides free software applications for Android phones. This month, F-Droid changed their documentation and guidance to now explicitly encourage RB for new apps [ ][ ], and FC Stegerman created an extremely in-depth issue on GitLab concerning the APK signing block. You can read more about F-Droid s approach to reproducibility in our July 2022 interview with Hans-Christoph Steiner of the F-Droid Project. In openSUSE, Bernhard M. Wiedemann published his usual openSUSE monthly report.

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:

diffoscope diffoscope is our in-depth and content-aware diff utility. Not only can it locate and diagnose reproducibility issues, it can provide human-readable diffs from many kinds of binary formats. This month, Chris Lamb prepared and uploaded versions 224 and 225 to Debian:
  • Add support for comparing the text content of HTML files using html2text. [ ]
  • Add support for detecting ordering-only differences in XML files. [ ]
  • Fix an issue with detecting ordering differences. [ ]
  • Use the capitalised version of Ordering consistently everywhere in output. [ ]
  • Add support for displaying font metadata using ttx(1) from the fonttools suite. [ ]
  • Testsuite improvements:
    • Temporarily allow the stable-po pipeline to fail in the CI. [ ]
    • Rename the order1.diff test fixture to json_expected_ordering_diff. [ ]
    • Tidy the JSON tests. [ ]
    • Use assert_diff over get_data and an manual assert within the XML tests. [ ]
    • Drop the ALLOWED_TEST_FILES test; it was mostly just annoying. [ ]
    • Tidy the tests/test_source.py file. [ ]
Chris Lamb also added a link to diffoscope s OpenBSD packaging on the diffoscope.org homepage [ ] and Mattia Rizzolo fix an test failure that was occurring under with LLVM 15 [ ].

Testing framework The Reproducible Builds project operates a comprehensive testing framework at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In October, the following changes were made by Holger Levsen:
  • Run the logparse tool to analyse results on the Debian Edu build logs. [ ]
  • Install btop(1) on all nodes running Debian. [ ]
  • Switch Arch Linux from using SHA1 to SHA256. [ ]
  • When checking Debian debstrap jobs, correctly log the tool usage. [ ]
  • Cleanup more task-related temporary directory names when testing Debian packages. [ ][ ]
  • Use the cdebootstrap-static binary for the 2nd runs of the cdebootstrap tests. [ ]
  • Drop a workaround when testing OpenWrt and coreboot as the issue in diffoscope has now been fixed. [ ]
  • Turn on an rm(1) warning into an info -level message. [ ]
  • Special case the osuosl168 node for running Debian bookworm already. [ ][ ]
  • Use the new non-free-firmware suite on the o168 node. [ ]
In addition, Mattia Rizzolo made the following changes:
  • Ensure that 2nd build has a merged /usr. [ ]
  • Only reconfigure the usrmerge package on Debian bookworm and above. [ ]
  • Fix bc(1) syntax in the computation of the percentage of unreproducible packages in the dashboard. [ ][ ][ ]
  • In the index_suite_ pages, order the package status to be the same order of the menu. [ ]
  • Pass the --distribution parameter to the pbuilder utility. [ ]
Finally, Roland Clobus continued his work on testing Live Debian images. In particular, he extended the maintenance script to warn when workspace directories cannot be deleted. [ ]

Alastair McKinstry: Government approves T&Cs for first offshore wind auction under the ...

Government approves T&Cs for first offshore wind auction under the Renewable Electricity Support Scheme ORESS 1 expected to secure 2.5GW of electricity generating capacity #GreensInGovernment The Government has today approved the Terms and Conditions of ORESS 1, the first auction for offshore wind under the Renewable Electricity Support Scheme. This is a seminal moment in the delivery of offshore wind in Ireland. The offshore auction, the first in Ireland's history, is expected to provide a route to market for up to 2.5GW of offshore renewable energy to the Irish grid, enough to power 2.5 million Irish homes with clean electricity. Coming during the weeks of COP27, publishing details of the auction sends a strong international signal that Ireland is serious about offshore energy and our national climate targets and obligations. Recognising the critical role of local hosting communities in the development of this critical infrastructure, all offshore wind projects developed via ORESS will be required to make Community Benefit Fund contributions, from construction phase and continuing for the duration of the support period, typically for a total period of 25 years. This will result in lasting, tangible benefits for these communities. Speaking about this development, Minister Ryan said: The publication of these ORESS 1 Terms and Conditions is another massive step forward for offshore wind, for Irish climate leadership and towards Ireland s future as an international green energy hub. The first stage of this transformative auction will start before Christmas and it sets us on a path to powering many more of our homes and businesses from our own green energy resources over the coming years. It follows the enactment of the Maritime Area Planning Act last year, and the announcement regarding the awarding of Maritime Area Consents to Phase One projects last month. A final ORESS 1 auction calendar will be published by EirGrid shortly. The pre-qualification stage will launch next month (December). The qualification stage and the auction process will take place in the first half of 2023. Final auction results will be published by June 2023. Eligible projects Any project that has been awarded a Maritime Area Consent is eligible to partake in the ORESS 1 auction. Seven projects known as Relevant Projects were deemed ready to apply for Maritime Area Consents in Spring 2022. Once Maritime Area Consents are granted, these projects can not only compete for State support via the ORESS, but can also apply for planning permission from An Bord Plean la. Delivering on our broader targets ORESS 1 is expected to procure approximately 2.5GW of electricity generating capacity. Further auctions will be required to meet our renewable energy and climate ambitions. At least three offshore energy auctions are currently planned for this decade. The aim is to progress enough viable offshore projects through the consenting system to have competitive auctions. This will ultimately drive down cost for electricity consumers.

Alastair McKinstry: 1.3 billion announced for new Forestry Support

1.3 billion announced for new Forestry Support Funds to be delivered through new Forestry Programme Premiums for planting trees to be increased by between 46% and 66% and extended to 20 years for farmers #GreensInGovernment The Taoiseach, Miche l Martin TD, Minister of State with responsibility for Forestry, Senator Pippa Hackett, and Minister for Agriculture, Food and the Marine, Charlie McConalogue T.D today announced a proposed investment by the Government of 1.3 billion in Irish forestry. The funding will be for the next national Forestry Programme and represents the largest ever investment by an Irish Government in tree-planting. The programme will now be the subject of state-aid approval by the European Commission. The Taoiseach said: This commitment by the Government to such a substantial financial package reflects the seriousness with which we view the climate change and biodiversity challenges, which affect all of society. Forestry is at the heart of delivering on our sustainability goals and strong support is needed to encourage engagement from all our stakeholders in reaching our objectives. Minister Hackett said: I m delighted to have secured a package of 1.318 billion for forestry. This will support the biggest and best-funded Forestry Programme ever in Ireland. It comes at an appropriate time, given the urgency of taking climate mitigation measures. Planting trees is one of the most effective methods of tackling climate change as well as contributing to improved biodiversity and water quality. One of my main aims is to re-engage farmers in afforestation. I m delighted therefore to be proposing a new 20-year premium term exclusively for farmers, as well as introducing a new small-scale native woodland scheme which will allow farmers to plant up to 1 hectare of native woodland on farmland and along watercourses outside of the forestry licensing process. Minister McConalogue said: Today we commit to providing unprecedented incentives to encourage the planting of trees that can provide a valuable addition to farm income and help to meet national climate and biodiversity objectives. This funding guarantees continued payments to those forest owners who planted under the current scheme and who are still in receipt of premiums. It also offers new and improved financial supports to those who undertake planting and sustainable forest management under the new Programme. We intend to increase premiums for planting trees by between 46% and 66% and to extend the premium period from 15 to 20 years for farmers. "We are approaching a new and exciting period for forestry in Ireland. The new Forestry Programme will drive a new and brighter future for forestry, for farmers and for our climate. The proposed new Forestry Programme is currently out to public consultation as part of the Strategic Environmental Assessment and Appropriate Assessment process. The Programme is the main implementation mechanism for the new Forest Strategy (2023 -2030) which reflects the ambitions contained in the recently published Shared National Vision for Trees, Woods and Forests in Ireland until 2050. The public consultation closes on 29th November, 2022 and any changes which result from this process will be incorporated into the Programme and the Forest Strategy. Minister Hackett commented: The draft Forestry Programme and Forest Strategy are the product of extensive stakeholder consultation and feedback, and both documents are open to public consultation for the next number of weeks. I would strongly encourage all interested parties to engage with the consultation in advance of the Strategy and Programme being finalised. The new Programme is built around the principle of right trees in the right places for the right reasons with the right management. It aims to deliver more diverse forest which will meet multiple societal objectives, economic, social and environmental. Higher grant rates for forest establishment are also proposed with increases of approximately 20% to reflect rising living costs. The new one hectare native tree area scheme will also make it easier for landowners who wish to plant small areas of trees on their farm. The Taoiseach concluded I welcome this milestone and I believe that this funding injection will be an important catalyst in delivering on the ambition outlined in the new Forest Strategy. Our environmental challenges are huge but so is our commitment to overcoming them and this Forestry Programme is key to delivering so many of our priorities. The new Programme will be 100% Exchequer funded and is subject to State Aid approval from the EU Commission. The Department is in contact with the Commission in relation to this approval which is a rigorous process.

Louis-Philippe V ronneau: Montreal's Debian & Stuff - October 2022

Our local Debian user group gathered on Sunday October 30th to chat, work on Debian and do other, non-Debian related hacking :) This time around, we met at EfficiOS's1 offices. As you can see from the following picture, it's a great place and the view they have is pretty awesome. Many thanks for hosting us! The view from EfficiOS' offices, overlooking the Mont-Royal This was our 4th meeting this year and once again, attendance was great: 10 people showed up to work on various things. Following our bi-monthly schedule, our next meeting should be in December, but I'm not sure it'll happen. December can be a busy month here and I will have to poke our mailing list to see if people have the spoons for an event. This time around, I was able to get a rough log of the Debian work people did: pollo: mjeanson: viashimo: lavamind: anarcat: babelouest: tvaz: As always, thanks to the Debian project for granting us a budget to buy some food!

Shirish Agarwal: Shantaram, The Pyramid, Japan s Hikikomori & Backpack

Shantaram I know I have been quite behind in review of books but then that s life. First up is actually not as much as a shocker but somewhat of a pleasant surprise. So, a bit of background before I share the news. If you have been living under a rock, then about 10-12 years ago a book called Shantaram was released. While the book is said to have been released in 2003/4 I got it in my hand around 2008/09 or somewhere around that. The book is like a good meal, a buffet. To share the synopsis, Lin a 20 something Australian guy gets involved with a girl, she encourages him to get into heroin, he becomes a heroin user. And drugs, especially hard drugs need constant replenishment, it is a chemical thing. So, to fund those cravings, he starts to steal, rising to rob a bank and while getting away shoots a cop who becomes dead. Now either he surrenders or is caught is unclear, but he is tortured in the jail. So one day, he escapes from prison, lands up at home of somebody who owes him a favor, gets some money, gets a fake passport and lands up in Mumbai/Bombay as it was then known. This is from where the actual story starts. And how a 6 foot something Australian guy relying on his street smartness and know how the transformation happens from Lin to Shantaram. Now what I have shared is perhaps just 5% of the synopsis, as shared the real story starts here. Now the good news, last week 4 episodes of Shantaram were screened by Apple TV. Interestingly, I have seen quite a number people turning up to buy or get this book and also sharing it on Goodreads. Now there seems to have been some differences from the book to TV. Now I m relying on 10-12 year back memory but IIRC Khaderbhai, one of the main characters who sort of takes Lin/Shantaram under his wing is an Indian. In the series, he is a western or at least looks western/Middle Eastern to me. Also, they have tried to reproduce 1980s in Mumbai/Bombay but dunno how accurate they were My impression of that city from couple of visits at that point in time where they were still more tongas (horse-ridden carriages), an occasional two wheelers and not many three wheelers. Although, it was one of the more turbulent times as lot of agitation for worker rights were happening around that time and a lot of industrial action. Later that led to lot of closure of manufacturing in Bombay and it became more commercial. It would be interesting to know whether they shot it in actual India or just made a set somewhere in Australia, where it possibly might have been shot. The chawl of the book needs a bit of arid land and Australia has lots of it. It is also interesting as this was a project that had who s who interested in it for a long time but somehow none of them was able to bring the project to fruition, the project seems to largely have an Australian cast as well as second generations of Indians growing in Australia. To take names, Amitabh Bacchan, Johnny Depp, Russel Crowe each of them wanted to make it into a feature film. In retrospect, it is good it was not into a movie, otherwise they would have to cut a lot of material and that perhaps wouldn t have been sufficient. Making it into a web series made sure they could have it in multiple seasons if people like it. There is a lot between now and 12 episodes to even guess till where it would leave you then. So, if you have not read the book and have some holidays coming up, can recommend it. The writing IIRC is easy and just flows. There is a bit of action but much more nuance in the book while in the web series they are naturally more about action. There is also quite a bit of philosophy between him and Kaderbhai and while the series touches upon it, it doesn t do justice but then again it is being commercially made. Read the book, see the series and share your thoughts on what you think. It is possible that the series might go up or down but am sharing from where I see it, may do another at the end of the season, depending on where they leave it and my impressions. Update A slight update from the last blog post. Seems Rishi Sunak seems would be made PM of UK. With Hunt as chancellor and Rishi Sunak, Austerity 2.0 seems complete. There have been numerous articles which share how austerity gives rises to fascism and vice-versa. History gives lot of lessons about the same. In Germany, when the economy was not good, it was all blamed on the Jews for number of years. This was the reason for rise of Hitler, and while it did go up by a bit, propaganda by him and his loyalists did the rest. And we know and have read about the Holocaust. Today quite a few Germans deny it or deny parts of it but that s how misinformation spreads. Also Hitler is looked now more as an aberration rather than something to do with the German soul. I am not gonna talk more as there is still lots to share and that actually perhaps requires its own blog post to do justice for the same.

The Pyramid by Henning Mankell I had actually wanted to review this book but then the bomb called Shantaram appeared and I had to post it above. I had read two-three books before it, but most of them were about multiple beheadings and serial killers. Enough to put anybody into depression. I do not know if modern crime needs to show crime and desperation of and to such a level. Why I and most loved and continue to love Sherlock Holmes as most stories were not about gross violence but rather a homage to the art of deduction, which pretty much seems to be missing in modern crime thrillers rather than grotesque stuff. In that, like a sort of fresh air I read/am reading the Pyramid by Henning Mankell. The book is about a character made by Monsieur Henning Mankell named Kurt Wallender. I am aware of the series called Wallender but haven t yet seen it. The book starts with Wallender as a beat cop around age 20 and on his first case. He is ambitious, wants to become a detective and has a narrow escape with death. I wouldn t go much into it as it basically gives you an idea of the character and how he thinks and what he does. He is more intuitive by nature and somewhat of a loner. Probably most detectives IRL are, dunno, have no clue. At least in the literary world it makes sense, in real world think there would be much irony for sure. This is speculation on my part, who knows. Back to the book though. The book has 5 stories a sort of prequel one could say but also not entirely true. The first case starts when he is a beat cop in 1969 and he is just a beat cop. It is a kind of a prequel and a kind of an anthology as he covers from the first case to the 1990s where he is ending his career sort of. Before I start sharing about the stories in the book, I found the foreword also quite interesting. It asks questions about the interplay of the role of welfare state and the Swedish democracy. Incidentally did watch couple of videos about a sort of mixed sort of political representation that happens in Sweden. It uses what is known as proportional representation. Ironically, Sweden made a turn to the far right this election season. The book was originally in Swedish and were translated to English by Ebba Segerberg and Laurie Thompson. While all the stories are interesting, would share the last three or at least ask the questions of intrigue. Of course, to answer them you would need to read the book So the last three stories I found the most intriguing. The first one is titled Man on the Beach. Apparently, a gentleman goes to one of the beaches, a sort of lonely beach, hails a taxi and while returning suddenly dies. The Taxi driver showing good presence of mind takes it to hospital where the gentleman is declared dead on arrival. Unlike in India, he doesn t run away but goes to the cafeteria and waits there for the cops to arrive and take his statement. Now the man is in his early 40s and looks to be fit. Upon searching his pockets he is found to relatively well-off and later it turns out he owns a couple of shops. So then here are the questions ? What was the man doing on a beach, in summer that beach is somewhat popular but other times not so much, so what was he doing there? How did he die, was it a simple heart attack or something more? If he had been drugged or something then when and how? These and more questions can be answered by reading the story Man on the Beach . 2. The death of a photographer Apparently, Kurt lives in a small town where almost all the residents have been served one way or the other by the town photographer. The man was polite and had worked for something like 40 odd years before he is killed/murdered. Apparently, he is murdered late at night. So here come the questions a. The shop doesn t even stock any cameras and his cash box has cash. Further investigation reveals it is approximate to his average takeout for the day. So if it s not for cash, then what is the motive ? b. The body was discovered by his cleaning staff who has worked for almost 20 years, 3 days a week. She has her own set of keys to come and clean the office? Did she give the keys to someone, if yes why? c. Even after investigation, there is no scandal about the man, no other woman or any vices like gambling etc. that could rack up loans. Also, nobody seems to know him and yet take him for granted till he dies. The whole thing appears to be quite strange. Again, the answers lie in the book. 3. The Pyramid Kurt is sleeping one night when the telephone rings. The scene starts with a Piper Cherokee, a single piston aircraft flying low and dropping something somewhere or getting somebody from/on the coast of Sweden. It turns and after a while crashes. Kurt is called to investigate it. Turns out, the plane was supposed to be destroyed. On crash, both the pilot and the passenger are into pieces so only dental records can prove who they are. Same day or a day or two later, two seemingly ordinary somewhat elderly women, spinsters, by all accounts, live above the shop where they sell buttons and all kinds of sewing needs of the town. They seem middle-class. Later the charred bodies of the two sisters are found :(. So here come the questions a.Did the plane drop something or pick something somebody up ? The Cherokee is a small plane so any plane field or something it could have landed up or if a place was somehow marked then could be dropped or picked up without actually landing. b. The firefighter suspects arson started at multiple places with the use of petrol? The question is why would somebody wanna do that? The sisters don t seem to be wealthy and practically everybody has bought stuff from them. They weren t popular but weren t also unpopular. c. Are the two crimes connected or unconnected? If connected, then how? d. Most important question, why the title Pyramid is given to the story. Why does the author share the name Pyramid. Does he mean the same or the original thing? He could have named it triangle. Again, answers to all the above can be found in the book. One thing I also became very aware of during reading the book that it is difficult to understand people s behavior and what they do. And this is without even any criminality involved in. Let s say for e.g. I die in some mysterious circumstances, the possibility of the police finding my actions in last days would be limited and this is when I have hearing loss. And this probably is more to do with how our minds are wired. And most people I know are much more privacy conscious/aware than I am.

Japan s Hikikomori Japan has been a curious country. It was more or less a colonizer and somewhat of a feared power till it dragged the U.S. unnecessarily in World War 2. The result of the two atom bombs and the restitution meant that Japan had to build again from the ground up. It is also in a seismically unstable place as they have frequent earthquakes although the buildings are hardened/balanced to make sure that vibrations don t tear buildings apart. Had seen years ago on Natgeo a documentary that explains all that. Apart from that, Japan was helped by the Americans and there was good kinship between them till the 1980s till it signed the Plaza Accord which enhanced asset price bubbles that eventually burst. Something from which they are smarting even today. Japan has a constitutional monarchy. A somewhat history lesson or why it exists even today can be found here. Asset price bubbles of the 1980s, more than 50 percent of the population on zero hour contracts and the rest tend to suffer from overwork. There is a term called Karoshi that explains all. An Indian pig-pen would be two, two and a half times larger than a typical Japanese home. Most Japanese live in micro-apartments called konbachiku . All of the above stresses meant that lately many young Japanese people have become Hikikomori. Bloomberg featured about the same a couple of years back. I came to know about it as many Indians are given the idea of Japan being a successful country without knowing the ills and issues it faces. Even in that most women get the wrong end of the short stick i.e. even it they manage to find jobs, it would be most back-breaking menial work. The employment statistics of Japan s internal ministry tells its own story.

If you look at the data above, it seems that the between 2002 and 2019, the share of zero hour contracts has increased while regular work has decreased. This also means that those on the bottom of the ladder can no longer afford a home. There is and was a viral video called Lost in Manboo that went viral few years ago. It is a perfect set of storms. Add to that the Fukushima nuclear incident about which I had shared a few years ago. While the workers are blamed but all design decisions are taken by the management. And as was shown in numerous movies, documentaries etc. Interestingly, and somewhat ironically, the line workers knew the correct things to do and correct decisions to take unlike the management. The shut-ins story is almost a decade or two decades old. It is similar story in South Korea but not as depressive as the in Japan. It is somewhat depressive story but needed to be shared. The stories shared in the bloomberg article makes your heart ache

Backpacks In and around 2015, I had bought a Targus backpack, very much similar to the Targus TSB194US-70 Motor 16-inch Backpack. That bag has given me a lot of comfort over the years but now has become frayed the zip sometimes work and sometimes doesn t. Unlike those days there are a bunch of companies now operating in India. There are eight different companies that I came to know about, Aircase, Harrisons Sirius, HP Oddyssey, Mokobara, Artic Hunter, Dell Pro Hybrid, Dell Roller Backpack and lastly the Decathlon Quechua Hiking backpack 32L NH Escape 500 . Now of all the above, two backpacks seem the best, the first one is Harrisons Sirius, with 45L capacity, I don t think I would need another bag at all. The runner-up is the Decathlon Quecha Hiking Backpack 32L. One of the better things in all the bags is that all have hidden pockets for easy taking in and out of passport while having being ant-theft. I do not have to stress how stressful it is to take out the passport and put it back in. Almost all the vendors have made sure that it is not a stress point anymore. The good thing about the Quecha is that they are giving 10 years warranty, the point to be asked is if that is does the warranty cover the zip. Zips are the first thing that goes out in bags.That actually has what happened to my current bag. Decathlon has a store in Wakad, Pune while I have reached out to the gentleman in charge of Harrisons India to see if they have a reseller in Pune. So hopefully, in next one week I should have a backpack that isn t spilling with things all over the place, whichever I m able to figure out.
