Conferences 2020 was unsurprisingly not a great year for conference attendance. I was fortunate enough to make it to FOSDEM and CopyleftConf 2020 - I didn t speak at either, but had plenty of interesting hallway track conversations as well as seeing some good talks. I hadn t been planning to attend DebConf20 due to time constraints, but its move to an entirely online conference meant I was able to attend a few talks at least. I have to say I don t like virtual conferences as much as the real thing; it s not as easy to have the casual chats at them, and it s also harder to carve out the exclusive time when you re at home. That said I spoke at NIDevConf this year, which was also fully virtual. It s not a Free Software focussed conference, but there s a lot of crossover in terms of technologies and I spoke on my experiences with Go, some of which are influenced by my packaging experiences within Debian.

Debian Most of my contributions to Free software happen within Debian. As part of the Data Protection Team I responded to various inbound queries to that team. Some of this involved chasing up other project teams who had been slow to respond - folks, if you re running a service that stores personal data about people then you need to be responsive to requests about it. The Debian Keyring was possibly my largest single point of contribution. We re in a roughly 3 month rotation of who handles the keyring updates, and I handled 2020.02.02, 2020.03.24, 2020.06.24, 2020.09.24 + 2020.12.24 For Debian New Members I m mostly inactive as an application manager - we generally seem to have enough available recently. If that changes I ll look at stepping in to help, but I don t see that happening. I continue to be involved in Front Desk, having various conversations throughout the year with the rest of the team, but there s no doubt Mattia and Pierre-Elliott are the real doers at present. In terms of package uploads I continued to work on gcc-xtensa-lx106, largely doing uploads to deal with updates to the GCC version or packaging (5, 6 + 7). sigrok had a few minor updates, libsigkrok 0.5.2-2, libsigrokdecode 0.5.3-2 as well as a new upstream release of Pulseview 0.4.2-1 and a fix to cope with change to QT 0.4.2-2. Due to the sigrok-firmware requirement on sdcc I also continued to help out there, updating to 4.0.0+dfsg-1 and doing some fixups in 4.0.0+dfsg-2. Despite still not writing an VHDL these days I continue to try and make sure ghdl is ok, because I found it a useful tool in the past. In 2020 that meant a new upstream release, 0.37+dfsg-1 along with a couple of more minor updates (0.37+dfsg-2 + 0.37+dfsg-3. libcli had a new upstream release, 1.10.4-1, and I did a long overdue update to sendip to the latest upstream release, 2.6-1 having been poked about an outstanding bug by the Reproducible Builds folk. OpenOCD is coming up to 4 years since its last stable release, but I did a snapshot upload to Debian experimental (0.10.0+g20200530-1) and a subsequent one to unstable (0.10.0+g20200819-1). There are also moves to produce a 0.11.0 release and I uploaded 0.11.0~rc1-1 as a result. libjaylink got a bump as a result (0.2.0-1) after some discussion with upstream.

OpenOCD On the subject of OpenOCD I ve tried to be a bit more involved upstream. I m not familiar enough with the intricacies of JTAG/SWD/the various architectures supported to contribute to the core, but I pushed the config for my HIE JTAG adapter upstream and try and review patches that don t require in depth hardware knowledge.

Linux I ve been contributing to the Linux kernel for a number of years now, mostly just minor bits here and there for issues I hit. This year I spent a lot of time getting support for the MikoTik RB3011 router upstreamed. That included the basic DTS addition, fixing up QCA8K to support SGMII CPU connections, adding proper 802.1q VLAN support to QCA8K and cleaning up an existing QCOM ADM driver that s required for the NAND. There were a number of associated bugfixes/minor changes found along the way too. It can be a little frustrating at times going round the review loop with submitting things upstream, but I do find it quite satisfying when it all comes together and I have no interest in weird vendor trees that just bitrot over time.

Software in the Public Interest I haven t sat on the board of SPI since 2015 but I was still acting as the primary maintainer of the membership website (with Martin Michlmayr as the other active contributor) and hosting it on my own machine. I managed to finally extricate myself from this role in August. I remain a contributing member.

Personal projects 2020 finally saw another release (0.6.0, followed swiftly by 0.6.1 to allow the upload of 0.6.1-1 to Debian) of onak. This release finally adds various improvements to deal with the hostility shown to the OpenPGP keyserver network in recent years, including full signature verification as an option. I fixed an oversight in my Digoo/1-wire temperature decoder and a bug that turned up on ARM but not MIPS in my mqtt-arp code. I should probably package it for Debian (even if I don t upload it), as I m running it on my RB3011 now.

• ruby-psych is broken (#959571)
• there are some random java failures on a few tests (no clue why)
• tests ran by raklelib/rspec.rake fail to run, maybe because the --pattern command line option isn't compatible with our version of rake? Utkarsh seemed to know why this happens.

• link to the Debian packages
• fix the Debian packages if they don't include the right files (maybe in a new binary package that just ships part of the source code?)

• the debian-puppet mailing list
• the debian-jobs mailing list
• the Debian Consultants index

Timeline

January Ski weekend. Skiing is awesome! Cancelling a US work trip since there will be more opportunities soon (har har!).

February Ski vacation. Yep, skiing is awesome. Can t wait for next season (har har!). Discussions about Covid start in the office, but more is this scary or just interesting? (yes, this was before casualties). Then things start escalating, work-from-home at least partially, etc. etc. Definitely not just intersting anymore. In Garmin-speak, I got ~700+ intensity minutes in February (correlates with activity time, but depends on intensity of the effort whether 1:1 or 2 intensity minutes for one wall-clock minute).

March Sometimes during the month, my workplace introduces mandatory WFH. I remember being the last person in our team in the office, on the last day we were allowed to work, and cleaning my desk/etc., thinking all this, and we ll be back in 3 weeks or so . Har har! I buy a webcam, just in case WFH gets extended. And start to increase my sports - getting double the intensity minutes (1500+).

April Switzerland enters the first, hard, lockdown. Or was it late March? Not entirely sure, but in my mind March was the opening, and April was the first main course. It is challenging, having to juggle family and work and stressed schedule, but also interesting. Looking back, I think I liked April the most, as people were actually careful at that time. I continue upgrading my home office - new sound system, so that I don t have to plug in/plug out cables. 1700+ intensity minutes this month.

May Continued WFH, somewhat routine now. My then internet provider started sucking hard, so I upgrade with good results. I m still happy, half a year later (quite happy, even). Still going strong otherwise, but waiting for summer vacation, whatever it will be. A tiny bit more effort, so 1800 intensity minutes in May.

June Switzerland relaxes the lock down, but not my company, so as the rest of the family goes out and about, I start feeling alone in the apartment. And somewhat angry at it, which impacts my sports (counter-intuitively), so I only get 1500 intensity minutes. I go and buy a coffee machine a real one, that takes beans and grinds them, so I get to enjoy the smell of freshly-ground coffee and the fun of learning about coffee beans, etc. But it occupies the time. On the work/job front, I think at this time I finally got a workstation for home, instead of a laptop (which was ultra-portable too), so together with the coffee machine, it feels like a normal work environment. Well, modulo all the people. At least I m not crying anymore every time I open a new tab in Chrome

July Situation is slowly going better, but no, not my company. Still mandatory WFH, with (if I recall correctly) one day per week allowed, and no meeting other people. I get angrier, but manage to channel my energy into sports, almost doubly my efforts in July - 2937 intensity minutes, not quite reaching the 3000 magic number. I buy more stuff to clean and take care of my bicycles, which I don t really use. So shopping therapy too.

August The month starts with a one week family vacation, but I take a bike too, so I manage to put in some effort (it was quite nice riding TBH). A bit of changes in the personal life (nothing unexpected), which complicates things a bit, but at this moment I really thought Switzerland is going to continue to decrease in infections/R-factor/etc. so things will get back to normal, right? My company expands a bit the work-from-office part, so I m optimistic. Sports wise, still going strong, 2500 intensity minutes, preparing for the single race this year.

September The personal life changes from August start to stabilise, so things become again routine, and I finally get to do a race. Life was good for an extended weekend (well, modulo race angst, but that s part of the fun), and I feel justified to take it slow the week after the race. And the week after that too. I end up the month with close, but not quite, 1900 intensity minutes.

October October starts with school holidays and a one week family vacation, but I feel demotivated. Everything is closing down again (well, modulo schools), and I actually have difficulty getting re-adjusted to no longer being alone in the apartment during the work hours. I only get ~1000 intensity minutes in October, mainly thanks to good late autumn weather and outside rides. And I start playing way more computer games. I also sell my PS4, hoping to get a PS5 next month.

November November continues to suck. I think my vacation in October was actually detrimental - it broke my rhythm, I don t really do sport anymore, not consistently at least, so I only get 700+ intensity minutes. And I keep playing computer games, even if I missed the PS5 ordering window; so I switch to PC gaming. My home office feels very crowded, so as kind of anti-shopping therapy, I sell tons of smallish stuff; can t believe how much crap I kept around while not really using it. I also manage to update/refresh all my Debian packages, since next freeze approaches. Better than for previous releases, so it feels good.

December December comes, end of the year, the much awaited vacation - which we decide to cancel due to the situation in whole of Switzerland (and neighbouring countries). I basically only play computer games, and get grand total of 345 activity minutes this month. And since my weight is inversely correlated to my training, I m basically back at my February weight, having lost all the gains I made during the year. I mean, having gained back all the fat I lost. Err, you know what I mean; I m back close to my high-watermark, which is not good.

Conclusion I was somehow hoping that the end of the year will allow me to reset and restart, but somehow - a few days into January - it doesn t really feel so. My sleep schedule is totally ruined, my motivation is so-so, and I think the way I crashed in October was much harder/worse than I realised at the time, but in a way expected for this crazy year. I have some projects for 2021 - or at least, I m trying to make up a project list - in order to get a bit more structure in my continued stuck inside the house part, which is especially terrible when on-call. I don t know how the next 3-6 months will evolve, but I m thankful that so far, we are all healthy. Actually, me personally I ve been healthier physically than in other years, due to less contact with other people. On the other side, thinking of all the health-care workers, or even service workers, my IT job is comfy and all I am is a spoiled person (I could write many posts on specifically this topic). I really need to up my willpower and lower my spoil level. Hints are welcome :( Wish everybody has a better year in 2021.

• If the remote machine is at a location with network access and you trust its physical security (remember that although it will store data encrypted at rest and will transport it encrypted, it will in most cases handle un-encrypted data during processing), you could of course send NNCP packets to it over the network at the same time you send them to your local backup system.
• Alternatively, if the remote location doesn t have network access or you want to keep it airgapped, you could transport the NNCP packets by USB drive to the remote end.
• Or, if you don t want to have any kind of processing capability remotely probably a wise move you could rotate the hard drives themselves, keeping one plugged in locally and unplugging the other to take it offsite.

• ZFS can calculate a diff based on an efficiently-stored previous local state (snapshot or bookmark), rather than a comparison to a remote state (rsync)
• ZFS "incremental" sends, while less efficient than rsync, are reasonably efficient, sending only changed blocks
• ZFS receive detects and enforces that the incremental source on the local machine must match the incremental source of the original stream, enforcing ordering
• Datasets using ZFS encryption can be sent in their encrypted state
• Incrementals can be done without a full scan of the filesystem

I have been researching old terminal and X games recently, and realized
that much of the code from 'xmille' originated from the terminal game
'mille', which is part of bsdgames.
...
[The copyright and license information] has been stripped out of all
code in the xmille distribution.  Also, none of the included materials
give credit to the original author, Ken Arnold.

1. Everything was a 32-bit computer back then; pointers and ints were both 32 bits, so you could cast them with wild abandon and cause no problems. Today, testing revealed segfaults in some corners of the code.
2. It's K&R C code. Remember that the first version of ANSI-C didn't come out until 1989, and it was years later that we could reliably expect to find an ANSI compiler with a random Unix box.
3. It's X11 code. Fortunately (?), X11 hasn't changed since these applications were written, so at least that part still works just fine. Imagine trying to build Windows or Mac OS code from the early 90's on a modern OS...

• KLabel. Shows a text string. It allows the string to be left, center or right justified. And that's about it.
• KCommand. A push button, which uses KLabel for the underlying presentation.
• KToggle. A push-on/push-off button, which uses KCommand for most of the implementation. Also supports 'radio groups' where pushing one on makes the others in the group turn off.
• KMenuButton. A button for bringing up a menu widget; this is some pretty simple behavior built on top of KCommand.
• KSimpleMenu, KSmeBSB, KSmeLine. These three create pop-up menus; KSimpleMenu creates a container which can hold any number of KSmeBSB (string) and KSmeLine (separator lines) objects).
• KTextLine. A single line text entry widget.

• Reviewed and merged a contribution from Peter Law to my django-cache-toolbox library for Django-based web applications, including explicitly requiring that cached relations are primary keys (#23) and improving the example in the README (#25).

• I took part in an interview with Vladimir Bejdo, an intern at the Software Freedom Conservancy, in order to talk about the Reproducible Builds project, my participation in software freedom, the importance of reproducibility in software development, and to have a brief discussion on the issues facing free software as a whole. The full interview can be found on Conservancy's webpages.

• As part of my duties of being on the board of directors of the Open Source Initiative, I attended its monthly meeting and participated in various licensing and other related discussions occurring on the internet. Unfortunately, I could not attend the parallel meeting for Software in the Public Interest this month.

• Submitted a draft academic paper to IEEE Software. The article (co-written by Stefano Zacchiroli) is aimed a fairly general audience. It first defines the overal problem and then provides insight into the challenges of actually making real-world software reproducible. It then outlines the experiences of the Reproducible Builds project in making large-scale software collections/supply-chains/ecosystems reproducible and concludes by describing the affinity between reproducibility efforts and quality assurance.
• Kept isdebianreproducibleyet.com up to date. [...]
• Submitted 11 patches in Debian to fix specific reproducibility issues in circlator, dvbstreamer, eric, jbbp, knot-resolver, libjs-qunit, mail-expire, osmo-mgw, python-pyramid, pyvows & sayonara.
• Categorised a huge number of packages and issues in the Reproducible Builds 'notes' repository.
• For disorderfs (our FUSE-based filesystem that deliberately introduces non-determinism into directory system calls in order to flush out reproducibility issues), I made the following changes:
  • Add support for testing on Salsa's CI system. [...][...][...][...]
  • Added a quick benchmark. [...]
• Drafted, published and publicised our monthly report, as well managed the project's various social media accounts.
• Contributed to a discussion about the recent 'SolarWinds' attack. [...]

• I also made a large number of changes to the main Reproducible Builds website and documentation, including applying a typo fix from Roland Clobus [...], fixed the draft detection logic (#28), added more academic articles to our list [...] and corrected a number of grammar issues [...][...].

• New features & bug fixes:
  • Normalise ret to retq in objdump output in order to support multiple versions of GNU binutils. (#976760)
  • Don't show any progress indicators when running zstd. (#226)
  • Correct the grammatical tense in the --debug log output. [...]
• Codebase improvements:
  • Update the debian/copyright file to match the copyright notices in the source tree. (#224)
  • Update various years across the codebase in .py copyright headers. [...]
  • Rewrite the filter routine that post-processes the output from readelf(1). [...]
  • Remove unnecessary PEP 263 encoding header lines; unnecessary after PEP 3120. [...]
  • Use minimal instead of basic as a variable name to match the underlying package name. [...]
  • Use pprint.pformat in the JSON comparator to serialise the differences from jsondiff. [...]

• Frontdesk duties, responding to user/developer questions, reviewing others' packages, participating in mailing list discussions, etc.
• Issued DLA 2477-1 for the Jupyter Notebook interactive notebook system, where a maliciously-crafted link could redirect the browser to a malicious/spoofed website. (CVE-2020-26215)
• Issued DLA 2491-1 and ELA-333-1 to fix two issues in OpenEXR, a set of tools to manipulate OpenEXR image files, often used in the computer-graphics industry for visual effects and animation. (CVE-2020-16588 & CVE-2020-16589)
• Issued DLA 2503-1 as it was discovered that there was an issue in node-ini, an .ini configuration file format parser/serialiser for Node.js, where an application could be exploited by a malicious input file.
