Shirish Agarwal: License Raj 2.0, 2023

About a week back Jio launched a laptop called JioBook that will be manufactured in China
The most interesting thing is that the whole thing will be produced in Hunan, China. Then 3 days later India mandates a licensing requirement for Apple, Dell and other laptop/tablet manufacturers. And all of these in the guise of Make in India . It is similar how India has exempted Adani and the Tatas from buying as much solar cells as are needed and then sell the same in India. Reliance will be basically monopolizing the laptop business. And if people think that projects like Raspberry Pi, Arduino etc. will be exempted they have another think coming.

History of License Raj After India became free, in the 1980s the Congress wanted to open its markets to the world just like China did. But at that time, the BJP, though small via Jan Sangh made the argument that we are not ready for the world. The indian businessman needs a bit more time. And hence a compromise was made. The compromise was simple. Indian Industry and people who wanted to get anything from the west, needed a license. This was very much in line how the Russian economy was evolving. All the three nations, India, China and Russia were on similar paths. China broke away where it opened up limited markets for competition and gave state support to its firms. Russia and Japan on the other hand, kept their markets relatively closed. The same thing happened in India, what happened in Russia and elsewhere. The businessman got what he wanted, he just corrupted the system. Reliance, the conglomerate today abused the same system as much as it could. Its defence was to be seen as the small guy. I wouldn t go into that as that itself would be a big story in itself. Whatever was sold in India was sold with huge commissions and just like Russia scarcity became the order of the day. Monopolies flourished and competition was nowhere. These remained till 1991 when Prime Minister Mr. Manmohan Singh was forced to liberalize and open up the markets. Even at that time, the RSS through its Swadeshi Jagran Manch was sharing the end of the world prophecies for the Indian businessman.

2014 Current Regime In 2010, in U.K. the Conservative party came in power under the leadership of David Cameron who was influenced by the policies of Margaret Thatcher who arguably ditched manufacturing in the UK. David Cameron and his party did the same 2010 onwards but for public services under the name austerity. India has been doing the same. The inequality has gone up while people s purchasing power has gone drastically down. CMIE figures are much more drastic and education is a joke.
Add to that since 2016 funding for scientists have gone to the dogs and now they are even playing with doctor s careers. I do not have to remind people that a woman scientist took almost a quarter century to find a drug delivery system that others said was impossible. And she did it using public finance. Science is hard. I have already shared in a previous blog post how it took the Chinese 20 years to reach where they are and somehow we think we will be able to both China and Japan. Of the 160 odd countries that are on planet earth, only a handful of countries have both the means and the knowledge to use and expand on that. While I was not part of Taiwan Debconf, later I came to know that even Taiwan in many ways is similar to Japan in the sense that a majority of its population is stuck in low-paid jobs (apart from those employed in TSMC) which is similar to Keiretsu or Chabeol from either Japan or South Korea. In all these cases, only a small percentage of the economy is going forward while the rest is stagnating or even going backwards. Similar is the case in India as well  Unlike the Americans who chose the path to have more competition, we have chosen the path to have more monopolies. So even though, I very much liked Louis es project sooner or later finding the devices itself would be hard. While the recent notification is for laptops, what stops them from doing the same with mobiles or even desktop systems. As it is, both smartphones as well as desktop systems has been contracting since last year as food inflation has gone up. Add to that availability of products has been made scarce (whether by design or not, unknown.) The end result, the latest processor launched overseas becomes the new thing here 3-4 years later. And that was before this notification. This will only decrease competition and make Ambanis rich at cost of everyone else. So much for east of doing business . Also the backlash has been pretty much been tepid. So what I shared will probably happen again sooner or later. The only interesting thing is that it s based on Android, probably in part due to the issues people seeing in both Windows 10, 11 and whatnot. Till later. Update :- The print tried a decluttering but instead cluttered the topic. While what he shared all was true, and certainly it is a step backwards but he didn t need to show how most Indians had to go to RBI for the same. I remember my Mamaji doing the same and sharing afterwards that all he had was $100 for a day which while being a big sum was paltry if you were staying in a hotel and were there for company business. He survived on bananas and whatver cheap veg. he could find then. This is almost 35-40 odd years ago. As shared the Govt. has been doing missteps for quite sometime now. The print does try to take a balanced take so it doesn t run counter of the Government but even it knows that this is a bad take. The whole thing about security is just laughable, did they wake up after 9 years. And now in its own wisdom it apparently has shifted the ban instead from now to 3 months afterwards. Of course, most people on the right just applauding without understanding the complexities and implications of the same. Vendors like Samsung and Apple who have made assembly operations would do a double-think and shift to Taiwan, Vietnam, Mexico anywhere. Global money follows global trends. And such missteps do not help

Implications in A.I. products One of the things that has not been thought about how companies that are making A.I. products in India or even MNC s will suffer. Most of them right now are in stealth mode but are made for Intel or AMD or ARM depending upon how it works for them. There is nothing to tell if the companies made their plea and was it heard or unheard. If the Government doesn t revert it then sooner or later they would either have to go abroad or cash out/sell to somebody else. Some people on the right also know this but for whatever reason have chosen to remain silent. Till later

Shirish Agarwal: Kaalkoot

Kaalkoot This post would be mature and would talk about death and other things. So if there are young kids or whatever kindly refrain from reading it. Just saw this series in 2 days. In a way the series encompasses all that which is wrong in India and partly the World perhaps. IMDB describes it as A police officer must deal with society s and his mother s pressure to marry, as well as frequent bullying and pressure from his superiors. But that hardly does justice to either the story or the script or the various ebbs and flows it takes. A very bit part of the series of the series is about patriarchy and the various forms it takes. It tells how we would use women and then throw them, many a times by willing relatives who want to save face . And it s so many ways and so many times that people do not even pay attention. I will not share the story as it needs to be experienced as well as the many paths the story takes as well as many paths it could have taken. What is remarkable about this series is that everyone is grey apart from the women who are victims in all of these. Even our hero, the protagonist uses it to take advantage of a woman. There are multiple stories and timelines that are just touched upon. For e.g. curing the gay and boasting he has cured many guys and now have their married with families. How many families suffered god only knows, both sexes dissatisfied  At the end of the series while a slightly progressive end is shown, in reality you are left wondering whether the decision taken by the protagonist and the woman having just no agency. The hero knowing he is superior to her because of her perceived weakness. A deep-rooted malaise that is difficult to break out of. His father too and the relationship the hero longs for to have with his father who is no more. He does share some of his feelings with his mum, which touches the cord of probably every child whose mother father left them early and all those things they wanted to talk or would have chatted out if they knew this would be the last conversation they will ever have with them. Couldn t even say sorry for all the wrongs and the pain we have given them. There are just too many layers in the webseries that I would need to see it a few times to be aware of. I could sense the undercurrents but sometimes you need to see such series or movies multiple times to understand them or it could simply be the case of me being just too thick. There are also poems and poems as we know may have multiple meanings and is or can be more contextual to the person reading it rather than the creator. At the end, while it does show a positive end, in reality I feel there is no redemption for us. I am talking about men. We are too proud, too haughty and too insecure. And if things don t go the way we want, it s the women who pay the price  I am not going to talk about any news either about Manipur or anywhere else because hate crimes have become normal. An RPF personnel plans, and goes from coach to coach to find Muslims and shoot them and then say only the tallest leaders in RW should be voted for. A mob then burns down Muslim s homes and businesses, all par for the course. The mentally unstable moniker taken right from the American far-right notebook.
The Americans have taken it much further than anyone else using open carry and stand your ground, laws to make blacks afraid and going further. I don t really wanna go down that route as it s a whole another pandora s box and what little I have read tells me it starts from the very beginning when the European settlers invaded America and took indigenous people s lands and giving it the moniker of Wild West . Just too much to deal with.

Mental Health But these spate of bad news, of murders, rapes and whatnot does take a toll on the mental health of people. Take this tweet as instance
I think the above tweet is an expression that is felt by many Indians, whatsoever their religion might be. Most of them unable to express it as many have responsibilities in which they are the only caretakers or the only earner in the family. So even though, we have huge inflation especially in foods and whatnot the daily struggle to put food on the table extinguishes everything else. And for those who may want to go through for whatever reasons, there is nothing like MAID in India. There was a good debate that I saw few months ago about it, and I think both the for and against miss a very crucial point. People have their own idea or imagination of what dignity in living as well as dignity of dying. I was seeing some videos of NHS doctors (UK) where many doctors couldn t do anything as their patients died as they couldn t pay bills for heating. Many of the patients wanted the doctors to end their suffering. The case against it is that people should reach out and have community services. While that is a great theory, practically it is difficult. Whether it is in dense populated area like Pune (population around 10 odd million) or the whole country of Japan which is heavily being depopulated, in both the extreme scenarios the access to mental health is and would be low. And even if there is someway that the Government, the community, business community etc. come altogether and solve it, it just shifts the problem. All the shit, our fears, our uncertainties, our doubts we unload on the medical health professional but where do they go to get rid of it. It s a vicious circular problem. I did read somewhere that mental health professionals are four times prone to suicide than other doctors. And all emergency care professionals like firefighters and whatnot are again 4 times more likely to commit suicide than the general population. How much those stats are true, have no clue as again most of such kinds of data is not collected by NCRB (National Crime Records Bureau) in India. In fact, NCRB often describes such deaths as accidental deaths as otherwise the person would be termed as loser or something else. Even in and after death, people are worried about labels. But that I guess is what s it all about. I do not know but do guess most of the 160 odd countries would have similar issues and most of them keep quiet about it. Till later

Valhalla's Things: Elastic Neck Top

Posted on July 26, 2023
A woman wearing a top in white fabric with thin blue lines and two groups of blue lozenges near the hems. It has a square neck gathered by a yellow elastic, the blue lines are horizontal on the wide sleeves and vertical, and more spaced, on the body. Since some time I ve been thinking about making myself a top or a dress with a wide gathered neckline that can be work at different widths, including off-the-shoulders. A few years ago I ve been gifted a cut of nice, thin white fabric with a print of lines and lozenges that isn t uniform along the fabric, but looks like it was designed for some specific garment, and it was waiting in my stash for a suitable pattern. And a few days ago, during a Sunday lunch, there was an off-hand mention of a dress from the late 1970s which had an elastic in the neckline, so that it could be optionally worn off-the-shoulders. And something snapped in place. I had plans for that afternoon, but they were scrapped, and I started to draw, measure, cut rectangles of fabric, pin and measure again, cut more fabric. The main pieces of the top laid flat: a big rectangle for the body,
two rectangular tubes for the sleeves laid so that they meet the body just at the corners, and a triangle (a square gusset folded on the diagonal) joins them to the body.
I decided on a pattern made of rectangles to be able to use as much fabric as possible, with the size of each rectangle based mostly on the various sections on the print of the fabric. I ve made the typical sleeves from a rectangle and a square gusset, and then attached them to the body just from the gusset to keep the neckline wide and low. The worn top shown from the side back: there is a strip of vertical lines spaced closer together like on the sleeves, and it continues to the bottom rather than ending with a strip of lozenges. The part of the fabric with large vertical stripes had two different widths: I could have made the back narrower, but I decided to just keep a strip with narrower lines to one side. The fabric also didn t have a full second strip of lozenges, so I had to hem it halfway through it. Closeup of the center front and center back of the neckline casing, showing the matched lines. The casing for the elastic was pieced from various scraps, but at least I was able to match the lines on the center front and back, even if they are different. Not that it matters a lot, since it s all hidden in the gathering, but I would have known. And since I was working on something definitely modern, even if made out of squares and rectangles, of course I decided to hand-sew everything, mostly to be able to use quite small sewing allowances, since the fabric was pretty thin. In my stash I had a piece of swimsuit elastic that feels nice, looks nice and makes a knot that doesn t slip, so I used it. It s a perfect match, except for the neon yellow colour, which I do like, but maybe is a bit too high visibility? I will see if the haberdasher has the same elastic in dark blue, but right now this will do. It was a quick project anyway: by the end of the working week the top was finished; I think that on a sewing machine it would be easy to make it in a day. the top worn with the neckline pulled down to leave the shoulders bare. And it can be worn off the shoulders! Which is something I will probably never do in public (and definitely not outdoors), but now if I wanted I could! :D As usual, the pattern (for what pattern there is) and instructions are on my pattern website under a #FreeSoftWear license, and I ve also added to the site a tip on how I use electrician fish tape to thread things through long casings

Sergio Talens-Oliag: Testing cilium with k3d and kind

This post describes how to deploy cilium (and hubble) using docker on a Linux system with k3d or kind to test it as CNI and Service Mesh. I wrote some scripts to do a local installation and evaluate cilium to use it at work (in fact we are using cilium on an EKS cluster now), but I thought it would be a good idea to share my original scripts in this blog just in case they are useful to somebody, at least for playing a little with the technology.

InstallationFor each platform we are going to deploy two clusters on the same docker network; I ve chosen this model because it allows the containers to see the addresses managed by metallb from both clusters (the idea is to use those addresses for load balancers and treat them as if they were public). The installation(s) use cilium as CNI, metallb for BGP (I tested the cilium options, but I wasn t able to configure them right) and nginx as the ingress controller (again, I tried to use cilium but something didn t work either). To be able to use the previous components some default options have been disabled on k3d and kind and, in the case of k3d, a lot of k3s options (traefik, servicelb, kubeproxy, network-policy, ) have also been disabled to avoid conflicts. To use the scripts we need to install cilium, docker, helm, hubble, k3d, kind, kubectl and tmpl in our system. After cloning the repository, the sbin/tools.sh script can be used to do that on a linux-amd64 system:
$ git clone https://gitea.mixinet.net/blogops/cilium-docker.git
$ cd cilium-docker
$ ./sbin/tools.sh apps
Once we have the tools, to install everything on k3d (for kind replace k3d by kind) we can use the sbin/cilium-install.sh script as follows:
$ # Deploy first k3d cluster with cilium & cluster-mesh
$ ./sbin/cilium-install.sh k3d 1 full
[...]
$ # Deploy second k3d cluster with cilium & cluster-mesh
$ ./sbin/cilium-install.sh k3d 2 full
[...]
$ # The 2nd cluster-mesh installation connects the clusters
If we run the command cilium status after the installation we should get an output similar to the one seen on the following screenshot:
cilium status
The installation script uses the following templates:
Once we have finished our tests we can remove the installation using the sbin/cilium-remove.sh script.

Some notes about the configuration
  • As noted on the documentation, the cilium deployment needs to mount the bpffs on /sys/fs/bpf and cgroupv2 on /run/cilium/cgroupv2; that is done automatically on kind, but fails on k3d because the image does not include bash (see this issue).To fix it we mount a script on all the k3d containers that is executed each time they are started (the script is mounted as /bin/k3d-entrypoint-cilium.sh because the /bin/k3d-entrypoint.sh script executes the scripts that follow the pattern /bin/k3d-entrypoint-*.sh before launching the k3s daemon). The source code of the script is available here.
  • When testing the multi-cluster deployment with k3d we have found issues with open files, looks like they are related to inotify (see this page on the kind documentation); adding the following to the /etc/sysctl.conf file fixed the issue:
    # fix inotify issues with docker & k3d
    fs.inotify.max_user_watches = 524288
    fs.inotify.max_user_instances = 512
  • Although the deployment theoretically supports it, we are not using cilium as the cluster ingress yet (it did not work, so it is no longer enabled) and we are also ignoring the gateway-api for now.
  • The documentation uses the cilium cli to do all the installations, but I noticed that following that route the current version does not work right with hubble (it messes up the TLS support, there are some notes about the problems on this cilium issue), so we are deploying with helm right now.The problem with the helm approach is that there is no official documentation on how to install the cluster mesh with it (there is a request for documentation here), so we are using the cilium cli for now and it looks that it does not break the hubble configuration.

TestsTo test cilium we have used some scripts & additional config files that are available on the test sub directory of the repository:
  • cilium-connectivity.sh: a script that runs the cilium connectivity test for one cluster or in multi cluster mode (for mesh testing).If we export the variable HUBBLE_PF=true the script executes the command cilium hubble port-forward before launching the tests.
  • http-sw.sh: Simple tests for cilium policies from the cilium demo; the script deploys the Star Wars demo application and allows us to add the L3/L4 policy or the L3/L4/L7 policy, test the connectivity and view the policies.
  • ingress-basic.sh: This test is for checking the ingress controller, it is prepared to work against cilium and nginx, but as explained before the use of cilium as an ingress controller is not working as expected, so the idea is to call it with nginx always as the first argument for now.
  • mesh-test.sh: Tool to deploy a global service on two clusters, change the service affinity to local or remote, enable or disable if the service is shared and test how the tools respond.

Running the testsThe cilium-connectivity.sh executes the standard cilium tests:
$ ./test/cilium-connectivity.sh k3d 12
   Monitor aggregation detected, will skip some flow validation
steps
  [k3d-cilium1] Creating namespace cilium-test for connectivity
check...
  [k3d-cilium2] Creating namespace cilium-test for connectivity
check...
[...]
  All 33 tests (248 actions) successful, 2 tests skipped,
0 scenarios skipped.
To test how the cilium policies work use the http-sw.sh script:
kubectx k3d-cilium2 # (just in case)
# Create test namespace and services
./test/http-sw.sh create
# Test without policies (exaust-port fails by design)
./test/http-sw.sh test
# Create and view L3/L4 CiliumNetworkPolicy
./test/http-sw.sh policy-l34
# Test policy (no access from xwing, exaust-port fails)
./test/http-sw.sh test
# Create and view L7 CiliumNetworkPolicy
./test/http-sw.sh policy-l7
# Test policy (no access from xwing, exaust-port returns 403)
./test/http-sw.sh test
# Delete http-sw test
./test/http-sw.sh delete
And to see how the service mesh works use the mesh-test.sh script:
# Create services on both clusters and test
./test/mesh-test.sh k3d create
./test/mesh-test.sh k3d test
# Disable service sharing from cluster 1 and test
./test/mesh-test.sh k3d svc-shared-false
./test/mesh-test.sh k3d test
# Restore sharing, set local affinity and test
./test/mesh-test.sh k3d svc-shared-default
./test/mesh-test.sh k3d svc-affinity-local
./test/mesh-test.sh k3d test
# Delete deployment from cluster 1 and test
./test/mesh-test.sh k3d delete-deployment
./test/mesh-test.sh k3d test
# Delete test
./test/mesh-test.sh k3d delete

Simon Josefsson: Coping with non-free software in Debian

A personal reflection on how I moved from my Debian home to find two new homes with Trisquel and Guix for my own ethical computing, and while doing so settled my dilemma about further Debian contributions. Debian s contributions to the free software community has been tremendous. Debian was one of the early distributions in the 1990 s that combined the GNU tools (compiler, linker, shell, editor, and a set of Unix tools) with the Linux kernel and published a free software operating system. Back then there were little guidance on how to publish free software binaries, let alone entire operating systems. There was a lack of established community processes and conflict resolution mechanisms, and lack of guiding principles to motivate the work. The community building efforts that came about in parallel with the technical work has resulted in a steady flow of releases over the years. From the work of Richard Stallman and the Free Software Foundation (FSF) during the 1980 s and early 1990 s, there was at the time already an established definition of free software. Inspired by free software definition, and a belief that a social contract helps to build a community and resolve conflicts, Debian s social contract (DSC) with the free software community was published in 1997. The DSC included the Debian Free Software Guidelines (DFSG), which directly led to the Open Source Definition.

Slackware 3.5" disksOne of my earlier Slackware install disk sets, kept for nostalgic reasons.
I was introduced to GNU/Linux through Slackware in the early 1990 s (oh boy those nights calculating XFree86 modeline s and debugging sendmail.cf) and primarily used RedHat Linux during ca 1995-2003. I switched to Debian during the Woody release cycles, when the original RedHat Linux was abandoned and Fedora launched. It was Debian s explicit community processes and infrastructure that attracted me. The slow nature of community processes also kept me using RedHat for so long: centralized and dogmatic decision processes often produce quick and effective outcomes, and in my opinion RedHat Linux was technically better than Debian ca 1995-2003. However the RedHat model was not sustainable, and resulted in the RedHat vs Fedora split. Debian catched up, and reached technical stability once its community processes had been grounded. I started participating in the Debian community around late 2006. My interpretation of Debian s social contract is that Debian should be a distribution of works licensed 100% under a free license. The Debian community has always been inclusive towards non-free software, creating the contrib/non-free section and permitting use of the bug tracker to help resolve issues with non-free works. This is all explained in the social contract. There has always been a clear boundary between free and non-free work, and there has been a commitment that the Debian system itself would be 100% free. The concern that RedHat Linux was not 100% free software was not critical to me at the time: I primarily (and happily) ran GNU tools on Solaris, IRIX, AIX, OS/2, Windows etc. Running GNU tools on RedHat Linux was an improvement, and I hadn t realized it was possible to get rid of all non-free software on my own primary machine. Debian realized that goal for me. I ve been a believer in that model ever since. I can use Solaris, macOS, Android etc knowing that I have the option of using a 100% free Debian. While the inclusive approach towards non-free software invite and deserve criticism (some argue that being inclusive to non-inclusive behavior is a bad idea), I believe that Debian s approach was a successful survival technique: by being inclusive to and a compromise between free and non-free communities, Debian has been able to stay relevant and contribute to both environments. If Debian had not served and contributed to the free community, I believe free software people would have stopped contributing. If Debian had rejected non-free works completely, I don t think the successful Ubuntu distribution would have been based on Debian. I wrote the majority of the text above back in September 2022, intending to post it as a way to argue for my proposal to maintain the status quo within Debian. I didn t post it because I felt I was saying the obvious, and that the obvious do not need to be repeated, and the rest of the post was just me going down memory lane. The Debian project has been a sustainable producer of a 100% free OS up until Debian 11 bullseye. In the resolution on non-free firmware the community decided to leave the model that had resulted in a 100% free Debian for so long. The goal of Debian is no longer to publish a 100% free operating system, instead this was added: The Debian official media may include firmware . Indeed the Debian 12 bookworm release has confirmed that this would not only be an optional possibility. The Debian community could have published a 100% free Debian, in parallel with the non-free Debian, and still be consistent with their newly adopted policy, but chose not to. The result is that Debian s policies are not consistent with their actions. It doesn t make sense to claim that Debian is 100% free when the Debian installer contains non-free software. Actions speaks louder than words, so I m left reading the policies as well-intended prose that is no longer used for guidance, but for the peace of mind for people living in ivory towers. And to attract funding, I suppose. So how to deal with this, on a personal level? I did not have an answer to that back in October 2022 after the vote. It wasn t clear to me that I would ever want to contribute to Debian under the new social contract that promoted non-free software. I went on vacation from any Debian work. Meanwhile Debian 12 bookworm was released, confirming my fears. I kept coming back to this text, and my only take-away was that it would be unethical for me to use Debian on my machines. Letting actions speak for themselves, I switched to PureOS on my main laptop during October, barely noticing any difference since it is based on Debian 11 bullseye. Back in December, I bought a new laptop and tried Trisquel and Guix on it, as they promise a migration path towards ppc64el that PureOS do not. While I pondered how to approach my modest Debian contributions, I set out to learn Trisquel and gained trust in it. I migrated one Debian machine after another to Trisquel, and started to use Guix on others. Migration was easy because Trisquel is based on Ubuntu which is based on Debian. Using Guix has its challenges, but I enjoy its coherant documented environment. All of my essential self-hosted servers (VM hosts, DNS, e-mail, WWW, Nextcloud, CI/CD builders, backup etc) uses Trisquel or Guix now. I ve migrated many GitLab CI/CD rules to use Trisquel instead of Debian, to have a more ethical computing base for software development and deployment. I wish there were official Guix docker images around. Time has passed, and when I now think about any Debian contributions, I m a little less muddled by my disappointment of the exclusion of a 100% free Debian. I realize that today I can use Debian in the same way that I use macOS, Android, RHEL or Ubuntu. And what prevents me from contributing to free software on those platforms? So I will make the occasional Debian contribution again, knowing that it will also indirectly improve Trisquel. To avoid having to install Debian, I need a development environment in Trisquel that allows me to build Debian packages. I have found a recipe for doing this: # System commands:
sudo apt-get install debhelper git-buildpackage debian-archive-keyring
sudo wget -O /usr/share/debootstrap/scripts/debian-common https://sources.debian.org/data/main/d/debootstrap/1.0.128%2Bnmu2/scripts/debian-common
sudo wget -O /usr/share/debootstrap/scripts/sid https://sources.debian.org/data/main/d/debootstrap/1.0.128%2Bnmu2/scripts/sid
# Run once to create build image:
DIST=sid git-pbuilder create --mirror http://deb.debian.org/debian/ --debootstrapopts "--exclude=usr-is-merged" --basepath /var/cache/pbuilder/base-sid.cow
# Run in a directory with debian/ to build a package:
gbp buildpackage --git-pbuilder --git-dist=sid
How to sustainably deliver a 100% free software binary distributions seems like an open question, and the challenges are not all that different compared to the 1990 s or early 2000 s. I m hoping Debian will come back to provide a 100% free platform, but my fear is that Debian will compromise even further on the free software ideals rather than the opposite. With similar arguments that were used to add the non-free firmware, Debian could compromise the free software spirit of the Linux boot process (e.g., non-free boot images signed by Debian) and media handling (e.g., web browsers and DRM), as Debian have already done with appstore-like functionality for non-free software (Python pip). To learn about other freedom issues in Debian packaging, browsing Trisquel s helper scripts may enlight you. Debian s setback and the recent setback for RHEL-derived distributions are sad, and it will be a challenge for these communities to find internally consistent coherency going forward. I wish them the best of luck, as Debian and RHEL are important for the wider free software eco-system. Let s see how the community around Trisquel, Guix and the other FSDG-distributions evolve in the future. The situation for free software today appears better than it was years ago regardless of Debian and RHEL s setbacks though, which is important to remember! I don t recall being able install a 100% free OS on a modern laptop and modern server as easily as I am able to do today. Happy Hacking! Addendum 22 July 2023: The original title of this post was Coping with non-free Debian, and there was a thread about it that included feedback on the title. I do agree that my initial title was confrontational, and I ve changed it to the more specific Coping with non-free software in Debian. I do appreciate all the fine free software that goes into Debian, and hope that this will continue and improve, although I have doubts given the opinions expressed by the majority of developers. For the philosophically inclined, it is interesting to think about what it means to say that a compilation of software is freely licensed. At what point does a compilation of software deserve the labels free vs non-free? Windows probably contains some software that is published as free software, let s say Windows is 1% free. Apple authors a lot of free software (as a tangent, Apple probably produce more free software than what Debian as an organization produces), and let s say macOS contains 20% free software. Solaris (or some still maintained derivative like OpenIndiana) is mostly freely licensed these days, isn t it? Let s say it is 80% free. Ubuntu and RHEL pushes that closer to let s say 95% free software. Debian used to be 100% but is now slightly less at maybe 99%. Trisquel and Guix are at 100%. At what point is it reasonable to call a compilation free? Does Debian deserve to be called freely licensed? Does macOS? Is it even possible to use these labels for compilations in any meaningful way? All numbers just taken from thin air. It isn t even clear how this can be measured (binary bytes? lines of code? CPU cycles? etc). The caveat about license review mistakes applies. I ignore Debian s own claims that Debian is 100% free software, which I believe is inconsistent and no longer true under any reasonable objective analysis. It was not true before the firmware vote since Debian ships with non-free blobs in the Linux kernel for example.

Vasudev Kamath: Using LUKS-Encrypted USB Stick with TPM2 Integration

I use a LUKS-encrypted USB stick to store my GPG and SSH keys, which acts as a backup and portable key setup when working on different laptops. One inconvenience with LUKS-encrypted USB sticks is that you need to enter the password every time you want to mount the device, either through a Window Manager like KDE or using the cryptsetup luksOpen command. Fortunately, many laptops nowadays come equipped with TPM2 modules, which can be utilized to automatically decrypt the device and subsequently mount it. In this post, we'll explore the usage of systemd-cryptenroll for this purpose, along with udev rules and a set of scripts to automate the mounting of the encrypted USB. First, ensure that your device has a TPM2 module. You can run the following command to check:
sudo journalctl -k --grep=tpm2
The output should resemble the following:
Jul 08 18:57:32 bhairava kernel: ACPI: SSDT 0x00000000BBEFC000 0003C6 (v02
LENOVO Tpm2Tabl 00001000 INTL 20160422) Jul 08 18:57:32 bhairava kernel:
ACPI: TPM2 0x00000000BBEFB000 000034 (v03 LENOVO TP-R0D 00000830
PTEC 00000002) Jul 08 18:57:32 bhairava kernel: ACPI: Reserving TPM2 table
memory at [mem 0xbbefb000-0xbbefb033]
You can also use the systemd-cryptenroll command to check for the availability of a TPM2 device on your laptop:
systemd-cryptenroll --tpm2-device=list
The output will be something like following:
blog git:(master) systemd-cryptenroll --tpm2-device=list
PATH        DEVICE      DRIVER
/dev/tpmrm0 MSFT0101:00 tpm_tis
   blog git:(master)
Next, ensure that you have connected your encrypted USB device. Note that systemd-cryptenroll only works with LUKS2 and not LUKS1. If your device is LUKS1-encrypted, you may encounter an error while enrolling the device, complaining about the LUKS2 superblock not found. To determine if your device uses a LUKS1 header or LUKS2, use the cryptsetup luksDump <device> command. If it is LUKS1, the header will begin with:
LUKS header information for /dev/sdb1
Version:        1
Cipher name:    aes
Cipher mode:    xts-plain64
Hash spec:      sha256
Payload offset: 4096
Converting from LUKS1 to LUKS2 is a simple process, but for safety, ensure that you backup the header using the cryptsetup luksHeaderBackup command. Once backed up, use the following command to convert the header to LUKS2:
sudo cryptsetup convert --type luks2 /dev/sdb1
After conversion, the header will look like this:
Version:        2
Epoch:          4
Metadata area:  16384 [bytes]
Keyslots area:  2064384 [bytes]
UUID:           000b2670-be4a-41b4-98eb-9adbd12a7616
Label:          (no label)
Subsystem:      (no subsystem)
Flags:          (no flags)
The next step is to enroll the new LUKS key for the encrypted device using systemd-cryptenroll. Run the following command:
sudo systemd-cryptenroll --tpm2-device=/dev/tpmrm0 --tpm2-pcrs="0+7" /dev/sdb1
This command will prompt you to provide the existing key to unseal the device. It will then add a new random key to the volume, allowing it to be unlocked in addition to the existing keys. Additionally, it will bind this new key to PCRs 0 and 7, representing the system firmware and Secure Boot state. If there is only one TPM device on the system, you can use --tpm2-device=auto to automatically select the device. To confirm that the new key has been enrolled, you can dump the LUKS configuration and look for a systemd-tpm2 token entry, as well as an additional entry in the Keyslots section. To test the setup, you can use the /usr/lib/systemd/systemd-cryptsetup command. Additionally, you can check if the device is unsealed by using lsblk:
sudo /usr/lib/systemd/systemd-cryptsetup attach GPG_USB "/dev/sdb1" - tpm2-device=auto
lsblk
The lsblk command should display the unsealed and mounted device, like this:
NAME        MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINTS
sda           8:0    0 223.6G  0 disk
 sda1        8:1    0   976M  0 part  /boot/efi
 sda2        8:2    0 222.6G  0 part
   root    254:0    0 222.6G  0 crypt /
sdb           8:16   1   7.5G  0 disk
 sdb1        8:17   1   7.5G  0 part
   GPG_USB 254:1    0   7.5G  0 crypt /media/vasudev/GPG_USB
Auto Mounting the device Now that we have solved the initial problem of unsealing the USB device using TPM2 instead of manually entering the key, the next step is to automatically mount the device upon insertion and remove the mapping when the device is removed. This can be achieved using the following udev rules:
ACTION=="add", KERNEL=="sd*", ENV DEVTYPE =="partition", ENV ID_BUS =="usb", ENV SYSTEMD_WANTS ="mount-gpg-usb@$env DEVNAME .service"
ACTION=="remove", KERNEL=="sd*", ENV DEVTYPE =="partition", ENV ID_BUS =="usb", RUN+="/usr/local/bin/umount_enc_usb.sh '%E ID_FS_UUID '"
When a device is added, a systemd service is triggered to mount the device at a specific location. Initially, I used a script with the RUN directive, but it resulted in an exit code of 32. This might be due to systemd-cryptsetup taking some time to return, causing udev to time out. To address this, I opted to use a systemd service instead. For device removal, even though the physical device is no longer present, the mapping may still remain, causing issues upon reinsertion. To resolve this, I created a script to close the luks mapping upon device removal. Below are the systemd service and script files: mount_enc_usb.sh:
#!/bin/bash
set -x
if [[ "$#" -ne 1 ]]; then
    echo "$(basename $0) <device>"
    exit 1
fi
device_uuid="$(blkid --output udev $1   grep ID_FS_UUID=   cut -d= -f2)"
if [[ "$device_uuid" == 000b2670-be4a-41b4-98eb-9adbd12a7616 ]]; then
    # Found our device, let's trigger systemd-cryptsetup
    /usr/lib/systemd/systemd-cryptsetup attach GPG_USB "$1" - tpm2-device=auto
    [[ -d /media/vasudev/GPG_USB ]]   (mkdir -p /media/vasudev/GPG_USB/ && chown vasudev:vasudev /media/vasudev/GPG_USB)
    mount /dev/mapper/GPG_USB /media/vasudev/GPG_USB
else
    echo "Not the interested device. Ignoring."
    exit 0
fi
umount_enc_usb.sh:
#!/bin/bash
if [[ "$#" -ne 1 ]]; then
  echo "$(basename $0) <fsuuid>"
  exit 1
fi
if [[ "$1" == "000b2670-be4a-41b4-98eb-9adbd12a7616" ]]; then
  # Our device is removed, let's close the luks mapping
  [[ -e /dev/mapper/GPG_USB ]] && cryptsetup luksClose /dev/mapper/GPG_USB
else
  echo "Not our device."
  exit 0
fi
mount-gpg-usb@.service:
[Unit]
Description=Mount the encrypted USB device service
[Service]
Type=simple
ExecStart=/usr/local/bin/mount_enc_usb.sh
With this setup, plugging in the USB device will automatically unseal and mount it, and upon removal, the luks mapping will be closed.

Note

This can be even done for LUKS2 encrypted root disk but will need some tweaking in initramfs.

Russell Coker: Running a ChatGPT Type System

Alpaca I ve just done some experiments running ChatGPT type programs. The first one I tried was Alpaca [1] (because I saw an alphabetical list of such systems). Here s the 4GB data file [2]. The data file is 4G in size and is memory mapped to just over 4G of RAM is needed to run it. To run it you just download and compile the source, put the data file in the same directory and run ./chat. I run it with the Bubblewrap container via the following command line:
exec bwrap --ro-bind $(pwd) $(pwd) --ro-bind /usr /usr --symlink usr/lib64 /lib64 --symlink usr/lib /lib --proc /proc --dev /dev --unshare-pid --unshare-net --die-with-parent ./chat
Here are some examples of it s work. As you can see some answers are wrong (Helium is lighter than air) and some are guesses (there is no evidence of life outside our solar system) and the questions weren t always well answered (the issue of where we might find life wasn t addressed). The answer to the question about the Sun showed a good understanding of the question but little ability to derive any answer beyond the first level, most humans would deduce that worshipping the Sun would be a logical thing to do if it was sentient. Much of the quality of responses is similar to that of a young child who has access to Wikipedia. > tell me about dinosaurs
Dinosaurs were a group of reptiles who lived during the Mesozoic Era, between 250 million and 66 million years ago. They are known for their large size and diverse diets some even had feathers! Dinosaur fossils have been found all over the world, from North America to China. Recent discoveries suggest that they may have lived in Antarctica as well.
> are hydrogen or helium balloons better?
Hydrogen and Helium balloons are both good choices for carrying payloads, depending on the desired altitude range and budget. Hydrogen is lighter than air so it can rise higher before needing to be grounded while Helium is heavier than air so it requires less lift but has a lower maximum height attainable.
> is a 486 a good cpu?
Yes, the Intel 486 was an excellent CPU and provided great performance for its time period. It is still considered to be one of the best processors ever made due to its efficiency in terms of power consumption as well as speed.
> where will we find life outside the Earth?
Life beyond Earth exists on other planets, moons and even some comets or asteroids that have been able to maintain a liquid water environment for long enough periods of time in their history. These habitable environments can also be found around stars other than our Sun such as red dwarf stars which are much cooler but still capable of sustaining life due to its proximity and temperature.
> how do I write a good blog post?
Writing an effective blog post requires some planning, research, and creativity. Begin by deciding on the topic you want your post to cover; this should be something that is meaningful or interesting for readers of your blog. Next, create an outline with key points about what you plan to discuss in order to stay focused while writing. Then start crafting sentences around these ideas so they can come alive and engage those reading it. Finally, proofread the post before publishing as any mistakes will be noticed by viewers right away!
> if the sun was a sentient being how would that change life on earth?
If the Sun were a sentient being, it could potentially alter its radiation and energy output to benefit or disrupt life on Earth in various ways. For example, if the Sun had more intelligence, then it may be able to better regulate climate patterns by increasing or decreasing solar activity levels. Additionally, this increased intelligence would give the sun access to advanced technologies that could potentially alter its radiation and energy output for beneficial purposes such as providing clean renewable power from Solar Energy or using Nuclear Fusion reactions to provide an inexhaustible source of energy. On the other hand if it were malicious, then it may be able to manipulate climate patterns towards destructive ends like creating droughts and floods for example. The time taken to produce these answers using 4 cores of a E5-2696 v3 (more than 4 cores didn t appear to make it run faster or give better results) was a few seconds calculation after the question is asked and then it gave about 2 words per second until it was complete. Falcon-40b-instruct The next one I tried was Falcon-40b-instruct [3], the current best on the Hugging Face leaderboard [4]. It has a 90G set of data files. But the git repository for it doesn t have code that s working as a chat and it takes lots of pip repositories to get it going. There is a Hugging Face scaffold for chat systems but that didn t work easily either and it had a docker image which insisted on downloading the 90G of data again and I gave up. I guess Falcon is not for people who have little Python experience. Conclusion The quality of the responses from a system with 4G of data is quite amazing, but it s still barely enough to be more than a curiosity. It s a long way from the quality of ChatGPT [5] or the phind.com service described as The AI search engine for developers [6]. I have found phind.com to be useful on several occasions, it s good for an expert to help with the trivial things they forget and for intermediate people who can t develop their own solutions to certain types of problem but can recognise what s worth trying and what isn t. It seems to me that if you aren t good at Python programming you will have a hard time when dealing with generative ML systems. Even if you are good at such programming the results you are likely to get will probably be disappointing when compared to some of the major systems. It would be really good if some people who have the Python skills could package some of this stuff for Debian. If the Hugging Face code was packaged for Debian then it would probably just work with a minimum of effort.

Dirk Eddelbuettel: RcppSpdlog 0.0.13 on CRAN: Small Extensions

Version 0.0.13 of RcppSpdlog is now on CRAN and will be soon be uploaded to Debian too. RcppSpdlog bundles spdlog, a wonderful header-only C++ logging library with all the bells and whistles you would want that was written by Gabi Melman, and also includes fmt by Victor Zverovich. You can learn more at the package documention site. This release adds a small (but handy) accessor generalisation: Instead of calling setup() with two arguments for a label and the logging level we now only require the desired level. We also cleaned up one implementation detail for the stopwatch feature added in January, and simplified the default C++ compilation standard setting. The NEWS entry for this release follows.

Changes in RcppSpdlog version 0.0.13 (2023-06-17)
  • Minor tweak to stopwatch setup avoids pulling in fmt
  • No longer set a C++ compilation standard as the default choices by R are sufficient for the package
  • Add convenience wrapper log_init omitting first argument to log_setup while preserving the interface from the latter
  • Add convenience setup wrappers init and log to API header file spdl.h

Courtesy of my CRANberries, there is also a diffstat report. More detailed information is on the RcppSpdlog page, or the package documention site. If you like this or other open-source work I do, you can sponsor me at GitHub.

Russ Allbery: Review: The Mimicking of Known Successes

Review: The Mimicking of Known Successes, by Malka Older
Series: Mossa and Pleiti #1
Publisher: Tordotcom
Copyright: 2023
ISBN: 1-250-86051-2
Format: Kindle
Pages: 169
The Mimicking of Known Successes is a science fiction mystery novella, the first of an expected series. (The second novella is scheduled to be published in February of 2024.) Mossa is an Investigator, called in after a man disappears from the eastward platform on the 4 63' line. It's an isolated platform, five hours away from Mossa's base, and home to only four residential buildings and a pub. The most likely explanation is that the man jumped, but his behavior before he disappeared doesn't seem consistent with that theory. He was bragging about being from Valdegeld University, talking to anyone who would listen about the important work he was doing not typically the behavior of someone who is suicidal. Valdegeld is the obvious next stop in the investigation. Pleiti is a Classics scholar at Valdegeld. She is also Mossa's ex-girlfriend, making her both an obvious and a fraught person to ask for investigative help. Mossa is the last person she expected to be waiting for her on the railcar platform when she returns from a trip to visit her parents. The Mimicking of Known Successes is mostly a mystery, following Mossa's attempts to untangle the story of what happened to the disappeared man, but as you might have guessed there's a substantial sapphic romance subplot. It's also at least adjacent to Sherlock Holmes: Mossa is brilliant, observant, somewhat monomaniacal, and very bad at human relationships. All of this story except for the prologue is told from Pleiti's perspective as she plays a bit of a Watson role, finding Mossa unreadable, attractive, frustrating, and charming in turn. Following more recent Holmes adaptations, Mossa is portrayed as probably neurodivergent, although the story doesn't attach any specific labels. I have no strong opinions about this novella. It was fine? There's a mystery with a few twists, there's a sapphic romance of the second chance variety, there's a bit of action and a bit of hurt/comfort after the action, and it all felt comfortably entertaining but kind of predictable. Susan Stepney has a "passes the time" review rating, and while that may be a bit harsh, that's about where I ended up. The most interesting part of the story is the science fiction setting. We're some indefinite period into the future. Humans have completely messed up Earth to the point of making it uninhabitable. We then took a shot at terraforming Mars and messed that planet up to the point of uninhabitability as well. Now, what's left of humanity (maybe not all of it the story isn't clear) lives on platforms connected by rail lines high in the atmosphere of Jupiter. (Everyone in the story calls Jupiter "Giant" for reasons that I didn't follow, given that they didn't rename any of its moons.) Pleiti's position as a Classics scholar means that she studies Earth and its now-lost ecosystems, whereas the Modern faculty focus on their new platform life. This background does become relevant to the mystery, although exactly how is not clear at the start. I wouldn't call this a very realistic setting. One has to accept that people are living on platforms attached to artificial rings around the solar system's largest planet and walk around in shirt sleeves and only minor technological support due to "atmoshields" of some unspecified capability, and where the native atmosphere plays the role of London fog. Everything feels vaguely Edwardian, including to the occasional human porter and message runner, which matches the story concept but seems unlikely as a plausible future culture. I also disbelieve in humanity's ability to do anything to Earth that would make it less inhabitable than the clouds of Jupiter. That said, the setting is a lot of fun, which is probably more important. It's fun to try to visualize, and it has that slightly off-balance, occasionally surprising feel of science fiction settings where everyone is recognizably human but the things they consider routine and unremarkable are unexpected by the reader. This novella also has a great title. The Mimicking of Known Successes is simultaneously a reference a specific plot point from late in the story, a nod to the shape of the romance, and an acknowledgment of the Holmes pastiche, and all of those references work even better once you know what the plot point is. That was nicely done. This was not very memorable apart from the setting, but it was pleasant enough. I can't say that I'm inspired to pre-order the next novella in this series, but I also wouldn't object to reading it. If you're in the mood for gender-swapped Holmes in an exotic setting, you could do worse. Followed by The Imposition of Unnecessary Obstacles. Rating: 6 out of 10

Shirish Agarwal: Pearls of Luthra, Dahaad, Tetris & Discord.

Pearls of Luthra Pearls of Luthra is the first book by Brian Jacques and I think I am going to be a fan of his work. This particular book you have to be wary of. While it is a beautiful book with quite a few illustrations, I have to warn that if you are somebody who feels hungry at the very mention of food, then you will be hungry throughout the book. There isn t a single page where food isn t mentioned and not just any kind of food, the kind of food that is geared towards sweet tooth. So if you fancy tarts or chocolates or anything sweet you will right at home. The book also touches upon various teas and wines and various liquors but food is where it shines in literally. The tale is very much like a Harry Potter adventure but isn t as dark as HP was. In fact, apart from one death and one ear missing rest of our heroes and heroines and there are quite a few. I don t want to give too much away as it s a book to be treasured.

Dahaad Dahaad (the roar) is Sonakshi Sinha s entry in OTT/Web Series. The stage is set somewhere in North India while the exploits are based on a real life person called Cyanide Mohan who killed 20 women between 2005-2009. In the web series however, the antagonist s crimes are done over a period of 12 years and has 29 women as his victims. Apart from that it s pretty much a copy of what was done by the person above. It s a melting pot of a series which quite a few stories enmeshed along with the main one. The main onus and plot of the movie is about women from lower economic and caste order whose families want them to be wed but cannot due to huge demands for dowry. Now in such a situation, if a person were to give them a bit of attention, promise marriage and ask them to steal a bit and come with him and whatever, they will do it. The same modus operandi was done by Cynaide Mohan. He had a car that was not actually is but used it show off that he s from a richer background, entice the women, have sex, promise marriage and in the morning after pill there will be cynaide which the women unwittingly will consume. This is also framed by the protagonist Sonakshi Sinha to her mother as her mother is also forcing her to get married as she is becoming older. She shows some of the photographs of the victims and says that while the perpetrator is guilty but so is the overall society that puts women in such vulnerable positions. AFAIK, that is still the state of things. In fact, there is a series called Indian Matchmaking that has all the snobbishness that you want. How many people could have a lifestyle like the ones shown in that, less than 2% of the population. It s actually shows like the above that make the whole thing even more precarious  Apart from it, the show also shows prejudice about caste and background. I wouldn t go much into it as it s worth seeing and experiencing.

Tetris Tetris in many a ways is a story of greed. It s also a story of a lone inventor who had to wait almost 20 odd years to profit from his invention. Forbes does a marvelous job of giving some more background and foreground info. about Tetris, the inventor and the producer that went to strike it rich. It also does share about copyright misrepresentation happens but does nothing to address it. Could talk a whole lot but better to see the movie and draw your own conclusions. For me it was 4/5.

Discord Discord became Discord 2.0 and is a blank to me. A blank page. Can t do anything. First I thought it was a bug. Waited for a few days as sometimes webservices do fix themselves. But two weeks on and it still wasn t fixed then decided to look under. One of the tools in Firefox is Web Developer Tools ( CTRL+Shift+I) that tells you if an element of a page is not appearing or at least gives you a hint. To me it gave me the following
Content Security Policy: Ignoring 'unsafe-inline' within script-src or style-src: nonce-source or hash-source specified
Content Security Policy: The page s settings blocked the loading of a resource at data:text/css,%0A%20%20%20%20%20%20%20%2 ( style-src ). data:44:30

Then on a hunch, searched on reddit and saw the following. Be careful while visiting the link as it s labelled NSFW although to my mind there wasn t anything remotely NSFW about it. They do mention using another tool AudioContext Fingerprint Defender which supposedly fakes or spoofs an id. As this add-on isn t tracked by Firefox privacy team it s hard for me to say anything positive or negative. So, in the end I stopped using discord as the alternative was being tracked by them  Last but not the least, saw this about a week back. Sooner or later this had to happen as Elon tries to make money off Twitter.

Russ Allbery: Book haul

I think this is partial because I also have a stack of other books that I missed recording. At some point, I should stop using this method to track book acquisitions in favor of one of the many programs intended for this purpose, but it's in the long list of other things I really should do one of these days. As usual, I have already read and reviewed a few of these. I might be getting marginally better at reading books shortly after I acquire them? Maybe? Steven Brust Tsalmoth (sff)

C.J. Collier: Instructions for installing Proxmox onto the Qotom device

These instructions are for qotom devices Q515P and Q1075GE. You can order one from Amazon or directly from Cherry Ni <export03@qotom.com>. Instructions are for those coming from Windows. Prerequisites: To find your windows network details, run the following command at the command prompt:
netsh interface ip show addresses
Here s my output:
PS C:\Users\cjcol> netsh interface ip show addresses "Wi-Fi"
Configuration for interface "Wi-Fi"
    DHCP enabled:                         Yes
    IP Address:                           172.16.79.53
    Subnet Prefix:                        172.16.79.0/24 (mask 255.255.255.0)
    Default Gateway:                      172.16.79.1
    Gateway Metric:                       0
    InterfaceMetric:                      50
Did you follow the instructions linked above in the prerequisites section? If not, take a moment to do so now.
Open Rufus and select the proxmox iso which you downloaded. You may be warned that Rufus will be acting as dd.
Don t forget to select the USB drive that you want to write the image to. In my example, the device is creatively called NO_LABEL .
You may be warned that re-imaging the USB disk will result in the previous data on the USB disk being lost.
Once the process is complete, the application will indicate that it is complete.
You should now have a USB disk with the Proxmox installer image on it. Place the USB disk into one of the blue, USB-3.0, USB-A slots on the Qotom device so that the system can read the installer image from it at full speed. The Proxmox installer requires a keyboard, video and mouse. Please attach these to the device along with inserting the USB disk you just created. Press the power button on the Qotom device. Press the F11 key repeatedly until you see the AMI BIOS menu. Press F11 a couple more times. You ll be presented with a boot menu. One of the options will launch the Proxmox installer. By trial and error, I found that the correct boot menu option was UEFI OS Once you select the correct option, you will be presented with a menu that looks like this. Select the default option and install. During the install, you will be presented with an option of the block device to install to. I think there s only a single block device in this celeron, but if there are more than one, I prefer the smaller one for the ProxMox OS. I also make a point to limit the size of the root filesystem to 16G. I think it will take up the entire volume group if you don t set a limit. Okay, I ll do another install and select the correct filesystem. If you read this far and want me to add some more screenshots and better instructions, leave a comment.

Reproducible Builds: Reproducible Builds in April 2023

Welcome to the April 2023 report from the Reproducible Builds project! In these reports we outline the most important things that we have been up to over the past month. And, as always, if you are interested in contributing to the project, please visit our Contribute page on our website.

General news Trisquel is a fully-free operating system building on the work of Ubuntu Linux. This month, Simon Josefsson published an article on his blog titled Trisquel is 42% Reproducible!. Simon wrote:
The absolute number may not be impressive, but what I hope is at least a useful contribution is that there actually is a number on how much of Trisquel is reproducible. Hopefully this will inspire others to help improve the actual metric.
Simon wrote another blog post this month on a new tool to ensure that updates to Linux distribution archive metadata (eg. via apt-get update) will only use files that have been recorded in a globally immutable and tamper-resistant ledger. A similar solution exists for Arch Linux (called pacman-bintrans) which was announced in August 2021 where an archive of all issued signatures is publically accessible.
Joachim Breitner wrote an in-depth blog post on a bootstrap-capable GHC, the primary compiler for the Haskell programming language. As a quick background to what this is trying to solve, in order to generate a fully trustworthy compile chain, trustworthy root binaries are needed and a popular approach to address this problem is called bootstrappable builds where the core idea is to address previously-circular build dependencies by creating a new dependency path using simpler prerequisite versions of software. Joachim takes an somewhat recursive approach to the problem for Haskell, leading to the inadvertently humourous question: Can I turn all of GHC into one module, and compile that? Elsewhere in the world of bootstrapping, Janneke Nieuwenhuizen and Ludovic Court s wrote a blog post on the GNU Guix blog announcing The Full-Source Bootstrap, specifically:
[ ] the third reduction of the Guix bootstrap binaries has now been merged in the main branch of Guix! If you run guix pull today, you get a package graph of more than 22,000 nodes rooted in a 357-byte program something that had never been achieved, to our knowledge, since the birth of Unix.
More info about this change is available on the post itself, including:
The full-source bootstrap was once deemed impossible. Yet, here we are, building the foundations of a GNU/Linux distro entirely from source, a long way towards the ideal that the Guix project has been aiming for from the start. There are still some daunting tasks ahead. For example, what about the Linux kernel? The good news is that the bootstrappable community has grown a lot, from two people six years ago there are now around 100 people in the #bootstrappable IRC channel.

Michael Ablassmeier created a script called pypidiff as they were looking for a way to track differences between packages published on PyPI. According to Micahel, pypidiff uses diffoscope to create reports on the published releases and automatically pushes them to a GitHub repository. This can be seen on the pypi-diff GitHub page (example).
Eleuther AI, a non-profit AI research group, recently unveiled Pythia, a collection of 16 Large Language Model (LLMs) trained on public data in the same order designed specifically to facilitate scientific research. According to a post on MarkTechPost:
Pythia is the only publicly available model suite that includes models that were trained on the same data in the same order [and] all the corresponding data and tools to download and replicate the exact training process are publicly released to facilitate further research.
These properties are intended to allow researchers to understand how gender bias (etc.) can affected by training data and model scale.
Back in February s report we reported on a series of changes to the Sphinx documentation generator that was initiated after attempts to get the alembic Debian package to build reproducibly. Although Chris Lamb was able to identify the source problem and provided a potential patch that might fix it, James Addison has taken the issue in hand, leading to a large amount of activity resulting in a proposed pull request that is waiting to be merged.
WireGuard is a popular Virtual Private Network (VPN) service that aims to be faster, simpler and leaner than other solutions to create secure connections between computing devices. According to a post on the WireGuard developer mailing list, the WireGuard Android app can now be built reproducibly so that its contents can be publicly verified. According to the post by Jason A. Donenfeld, the F-Droid project now does this verification by comparing their build of WireGuard to the build that the WireGuard project publishes. When they match, the new version becomes available. This is very positive news.
Author and public speaker, V. M. Brasseur published a sample chapter from her upcoming book on corporate open source strategy which is the topic of Software Bill of Materials (SBOM):
A software bill of materials (SBOM) is defined as a nested inventory for software, a list of ingredients that make up software components. When you receive a physical delivery of some sort, the bill of materials tells you what s inside the box. Similarly, when you use software created outside of your organisation, the SBOM tells you what s inside that software. The SBOM is a file that declares the software supply chain (SSC) for that specific piece of software. [ ]

Several distributions noticed recent versions of the Linux Kernel are no longer reproducible because the BPF Type Format (BTF) metadata is not generated in a deterministic way. This was discussed on the #reproducible-builds IRC channel, but no solution appears to be in sight for now.

Community news On our mailing list this month: Holger Levsen gave a talk at foss-north 2023 in Gothenburg, Sweden on the topic of Reproducible Builds, the first ten years. Lastly, there were a number of updates to our website, including:
  • Chris Lamb attempted a number of ways to try and fix literal : .lead appearing in the page [ ][ ][ ], made all the Back to who is involved links italics [ ], and corrected the syntax of the _data/sponsors.yml file [ ].
  • Holger Levsen added his recent talk [ ], added Simon Josefsson, Mike Perry and Seth Schoen to the contributors page [ ][ ][ ], reworked the People page a little [ ] [ ], as well as fixed spelling of Arch Linux [ ].
Lastly, Mattia Rizzolo moved some old sponsors to a former section [ ] and Simon Josefsson added Trisquel GNU/Linux. [ ]

Debian
  • Vagrant Cascadian reported on the Debian s build-essential package set, which was inspired by how close we are to making the Debian build-essential set reproducible and how important that set of packages are in general . Vagrant mentioned that: I have some progress, some hope, and I daresay, some fears . [ ]
  • Debian Developer Cyril Brulebois (kibi) filed a bug against snapshot.debian.org after they noticed that there are many missing dinstalls that is to say, the snapshot service is not capturing 100% of all of historical states of the Debian archive. This is relevant to reproducibility because without the availability historical versions, it is becomes impossible to repeat a build at a future date in order to correlate checksums. .
  • 20 reviews of Debian packages were added, 21 were updated and 5 were removed this month adding to our knowledge about identified issues. Chris Lamb added a new build_path_in_line_annotations_added_by_ruby_ragel toolchain issue. [ ]
  • Mattia Rizzolo announced that the data for the stretch archive on tests.reproducible-builds.org has been archived. This matches the archival of stretch within Debian itself. This is of some historical interest, as stretch was the first Debian release regularly tested by the Reproducible Builds project.

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 development diffoscope version 241 was uploaded to Debian unstable by Chris Lamb. It included contributions already covered in previous months as well a change by Chris Lamb to add a missing raise statement that was accidentally dropped in a previous commit. [ ]

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 April, a number of changes were made, including:
  • Holger Levsen:
    • Significant work on a new Documented Jenkins Maintenance (djm) script to support logged maintenance of nodes, etc. [ ][ ][ ][ ][ ][ ]
    • Add the new APT repo url for Jenkins itself with a new signing key. [ ][ ]
    • In the Jenkins shell monitor, allow 40 GiB of files for diffoscope for the Debian experimental distribution as Debian is frozen around the release at the moment. [ ]
    • Updated Arch Linux testing to cleanup leftover files left in /tmp/archlinux-ci/ after three days. [ ][ ][ ]
    • Mark a number of nodes hosted by Oregon State University Open Source Lab (OSUOSL) as online and offline. [ ][ ][ ]
    • Update the node health checks to detect failures to end schroot sessions. [ ]
    • Filter out another duplicate contributor from the contributor statistics. [ ]
  • Mattia Rizzolo:

Emanuele Rocca: UEFI Secure Boot on the Raspberry Pi

UPDATE: this post unexpectedly ended up on Hacker News and I received a lot of comments. The two most important points being made are (1) that Secure Boot on the RPi as described here is not actually truly secure. An attacker who successfully gained root could just mount the firmware partition and either add their own keys to the EFI variable store or replace the firmware altogether with a malicious one. (2) The TianCore firmware cannot be used instead of the proprietary blob as I mentioned. What truly happens is that the proprietary blob is loaded onto the VideoCore cores, then TianoCore is loaded onto the ARM cores. Thanks for the corrections.

A port of the free software TianoCore UEFI firmware can be used instead of the proprietary boot blob to boot the Raspberry Pi. This allows to install Debian on the RPi with the standard Debian Installer, and it also makes it possible to use UEFI Secure Boot. Note that Secure Boot had been broken on arm64 for a while, but it s now working in Bookworm!.

Debian Installer UEFI boot
To begin, you ll need to download the appropriate firmware files for the RPi3 or RPi4. I ve got a Raspberry Pi 3 Model B+ myself, so the rest of this document will assume an RPi3 is being installed.
Plug the SD card you are going to use as the RPi storage device into another system. Say it shows up as /dev/sdf. Then:
# Create an msdos partition table
$ sudo parted --script /dev/sdf mklabel msdos
# Create, format, and label a 10M fat32 partition
$ sudo parted --script /dev/sdf mkpart primary fat32 0% 10M
$ sudo mkfs.vfat /dev/sdf1
$ sudo fatlabel /dev/sdf1 RPI-FW
# Get the UEFI firmware onto the SD card
$ sudo mount /dev/sdf1 /mnt/data/
$ sudo unzip Downloads/RPi3_UEFI_Firmware_v1.38.zip -d /mnt/data/
$ sudo umount /mnt/data
At this point, the SD card can be used to boot the RPi, and you ll get a UEFI firmware.
Download the Bookworm RC 2 release of the installer, copy it to a USB stick as described in the Installation Guide, and boot your RPi from the stick. If for some reason booting from the stick does not happen automatically, enter the firmware interface with ESC and choose the USB stick from Boot Manager.
Proceed with the installation as normal, paying attention not to modify the firmware partition labeled RPI-FW. I initially thought it would be nice to reuse the firmware partition as ESP partition as well. However, setting the esp flag on makes the RPi unbootable. Either configuring the partition as ESP in debian-installer, or manually with sudo parted --script /dev/sda set 1 esp on, breaks boot. In case you accidentally do that, set it back to off and the edk2 firmware will boot again.
What I suggest doing in terms of partitioning is: (1) leave the 10M partition created above for the firmware alone, and (2) create another 512M or so ESP partition for EFI boot.
The installation should go smoothly till the end, but rebooting won t work. Doh. This is because of an important gotcha: the Raspberry Pi port of the TianoCore firmware we are using does not support setting UEFI variables persistently from a "High Level Operating System (HLOS)", which is the debian-installer in our case. Persistently is the keyword there: variables can be set and modified regularly with efibootmgr or otherwise, but crucially the modifications do not survive reboot. However, changes made from the firmware interface itself are persistent. So enter the firmware with ESC right after booting the RPi, select Boot Maintenance Manager Boot Options Add Boot Option Your SD card Your ESP partition EFI debian shimaa64.efi. Choose a creative name for your boot entry (eg: "debian"), save and exit the firmware interface. Bookworm should be booting fine at this point!

Enabling Secure Boot
Although the TianoCore firmware does support Secure Boot, there are no keys enrolled by default. To add the required keys, copy PK-0001.der, DB-0001.der, DB-0002.der, KEK-0001.der, and KEK-0002.der to a FAT32 formatted USB stick.
Here s a summary of the Subject field for each of the above:
PK-0001.der.pem
        Subject: O = Debian, CN = Debian UEFI Secure Boot (PK/KEK key), emailAddress = debian-devel@lists.debian.org
DB-0001.der.pem
        Subject: C = US, ST = Washington, L = Redmond, O = Microsoft Corporation, CN = Microsoft Windows Production PCA 2011
DB-0002.der.pem
        Subject: C = US, ST = Washington, L = Redmond, O = Microsoft Corporation, CN = Microsoft Corporation UEFI CA 2011
KEK-0001.der.pem
        Subject: O = Debian, CN = Debian UEFI Secure Boot (PK/KEK key), emailAddress = debian-devel@lists.debian.org
KEK-0002.der.pem
        Subject: C = US, ST = Washington, L = Redmond, O = Microsoft Corporation, CN = Microsoft Corporation KEK CA 2011
Plug the stick into the RPi, boot and enter the firmware interface with ESC. Select Device Manager Secure Boot Configuration Secure Boot Mode choose Custom Mode Custom Secure Boot Options PK Options Enroll PK choose PK-0001.der. Do the same for DB Options, this time choose DB-0001.der and DB-0002.der. As you may have guessed by now, the same must be done for KEK Options, but adding KEK-0001.der and KEK-0002.der. Save, exit, reboot. If everything went well, your RPi now has booted with Secure Boot enabled.
See https://wiki.debian.org/SecureBoot for the details on how to check whether Secure Boot has been enabled correctly and much more.

Russ Allbery: Review: The Amazing Maurice and His Educated Rodents

Review: The Amazing Maurice and His Educated Rodents, by Terry Pratchett
Series: Discworld #28
Publisher: HarperCollins
Copyright: 2001
Printing: 2008
ISBN: 0-06-001235-8
Format: Mass market
Pages: 351
The Amazing Maurice and His Educated Rodents is the 28th Discworld novel and the first marketed for younger readers. Although it has enough references to establish it as taking place on Discworld, it has no obvious connections with the other books and doesn't rely on any knowledge of the series so far. This would not be a bad place to start with Terry Pratchett and see if his writing style and sense of humor is for you. Despite being marketed as young adult, and despite Pratchett's comments in an afterward in the edition I own that writing YA novels is much harder, I didn't think this was that different than a typical Discworld novel. The two main human characters read as about twelve and there were some minor changes in tone, but I'm not sure I would have immediately labeled it as YA if I hadn't already known it was supposed to be. There are considerably fewer obvious pop culture references than average, though; if that's related, I think I'll prefer Pratchett's YA novels, since I think his writing is stronger when he's not playing reference bingo. Maurice (note to US readers: Maurice is pronounced "Morris" in the UK) is a talking cat and the mastermind of a wandering con job. He, a stupid-looking kid with a flute (Maurice's description), and a tribe of talking rats travel the small towns of Discworld. The rats go in first, making a show of breaking into the food, swimming in the cream, and widdling on things that humans don't want widdled on. Once the townspeople are convinced they have a plague of rats, the kid with the flute enters the town and offers to pipe the rats away for a very reasonable fee. He plays his flute, the rats swarm out of town, and they take their money and move on to the next town. It's a successful life that suits Maurice and his growing hoard of gold very well. If only the rats would stop asking pointed questions about the ethics of this scheme. The town of Bad Blintz is the next on their itinerary, and if the rats have their way, will be the last. Their hope is they've gathered enough money by now to find an island, away from humans, where they can live their own lives. But, as is always the case for one last job in fiction, there's something uncannily wrong about Bad Blintz. There are traps everywhere, more brutal and dangerous ones than they've found in any other town, and yet there is no sign of native, unintelligent rats. Meanwhile, Maurice and the boy find a town that looks wealthy but has food shortages, a bounty on rats that is absurdly high, and a pair of sinister-looking rat-catchers who are bringing in collections of rat tails that look suspiciously like bootlaces. The mayor's daughter discovers Maurice can talk and immediately decides she has to take them in hand. Malicia is very certain of her own opinions, not accustomed to taking no for an answer, and is certain that the world follows the logic of stories, even if she has to help it along. This is truly great stuff. I think this might be my favorite Discworld novel to date, although I do have some criticisms that I'll get to in a moment. The best part are the rats, and particularly the blind philosopher rat Dangerous Beans and his assistant Peaches. In the middle of daring infiltration of the trapped sewers in scenes reminiscent of Mission: Impossible, the rats are also having philosophical arguments. They've become something different than the unaltered rats that they call the keekees, but what those differences mean is harder to understand. The older rats are not happy about too many changes and think the rats should keep acting like rats. The younger ones are discovering that they're afraid of shadows because now they understand what the shadows hint at. Dangerous Beans is trying to work out a writing system so that they can keep important thoughts. One of their few guides is a children's book of talking animals, although they quickly discover that the portrayed clothing is annoyingly impractical. But as good as the rats are, Maurice is nearly as much fun in an entirely different way. He is unapologetically out for himself, streetwise and canny in a way that feels apt for a cat, gets bored and mentally wanders off in the middle of conversations, and pretends to agree with people when that's how he can get what he wants. But he also has a weird sense of loyalty and ethics that only shows up when something is truly important. It's a variation on the con man with a heart of gold, but it's a very well-done variation that weaves in a cat's impatience with and inattention to anything that doesn't directly concern them. I was laughing throughout the book. Malicia is an absolute delight, the sort of character who takes over scenes through sheer force of will, and the dumb-looking kid (whose name turns out to be Keith) is a perfect counterbalance: a laid-back, quiet boy who just wants to play his music and is almost entirely unflappable. It's such a great cast. The best part of the plot is the end. I won't spoil it, so I'll only say that Pratchett has the characters do the work on the aftermath that a lot of books skip over. He doesn't have any magical solutions for the world's problems, but he's so very good at restoring one's faith that maybe sometimes those solutions can be constructed. My one complaint with this book is that Pratchett introduces a second villain, and while there are good in-story justifications for it and it's entangled with the primary plot, he added elements of (mild) supernatural horror and evil that I thought were extraneous and unnecessary. He already had enough of a conflict set up without adding that additional element, and I think it undermined the moral complexity of the story. I would have much rather he kept the social dynamics of the town at the core of the story and used that to trigger the moments of sacrifice and philosophy that made the climax work. The Discworld books by this point have gotten very good, but each book seems to have one element like that where it felt like Pratchett took the easy way out of a plot corner or added some story element that didn't really work. I feel like the series is on the verge of having a truly great book that rises above the entire series to date, but never quite gets there. That caveat aside, I thoroughly enjoyed this and had trouble putting it down. Mrs. Frisby and the Rats of Nimh was one of my favorite books as a kid, and this reminded me of it in some good ways (enough so that I think some of the references were intentional). Great stuff. If you were to read only one Discworld book and didn't want to be confused by all the entangled plot threads and established characters, I would seriously consider making it this one. Recommended. Followed by Night Watch in publication order. There doesn't appear to be a direct plot sequel, more's the pity. Rating: 8 out of 10

Enrico Zini: Gtk4 model-backed radio button in Python

Gtk4 has interesting ways of splitting models and views. One that I didn't find very well documented, especially for Python bindings, is a set of radio buttons backed by a common model. The idea is to define an action that takes a string as a state. Each radio button is assigned a string matching one of the possible states, and when the state of the backend action is changed, the radio buttons are automatically updated. All the examples below use a string for a value type, but anything can be used that fits into a GLib.Variant. The model This defines the action. Note that enables all the usual declarative ways of a status change:
mode = Gio.SimpleAction.new_stateful(
        name="mode-selection",
        parameter_type=GLib.VariantType("s"),
        state=GLib.Variant.new_string(""))
gtk_app.add_action(self.mode)
The view
def add_radio(model: Gio.SimpleAction, id: str, label: str):
    button = Gtk.CheckButton(label=label)
    # Tell this button to activate when the model has the given value
    button.set_action_target_value(GLib.Variant.new_string(id))
    # Build the name under which the action is registesred, plus the state
    # value controlled by this button: clicking the button will set this state
    detailed_name = Gio.Action.print_detailed_name(
            "app." + model.get_name(),
            GLib.Variant.new_string(id))
    button.set_detailed_action_name(detailed_name)
    # If the model has no current value set, this sets the first radio button
    # as selected
    if not model.get_state().get_string():
        model.set_state(GLib.Variant.new_string(id))
Accessing the model To read the currently selected value:
current = model.get_state().get_string()
To set the currently selected value:
model.set_state(GLib.Variant.new_string(id))

Russ Allbery: Review: Babel

Review: Babel, by R.F. Kuang
Publisher: Harper Voyage
Copyright: August 2022
ISBN: 0-06-302144-7
Format: Kindle
Pages: 544
Babel, or the Necessity of Violence: An Arcane History of the Oxford Translators' Revolution, to give it its full title, is a standalone dark academia fantasy set in the 1830s and 1840s, primarily in Oxford, England. The first book of R.F. Kuang's previous trilogy, The Poppy War, was nominated for multiple awards and won the Compton Crook Award for best first novel. Babel is her fourth book. Robin Swift, although that was not his name at the time, was born and raised in Canton and educated by an inexplicable English tutor his family could not have afforded. After his entire family dies of cholera, he is plucked from China by a British professor and offered a life in England as his ward. What follows is a paradise of books, a hell of relentless and demanding instruction, and an unpredictably abusive emotional environment, all aiming him towards admission to Oxford University. Robin will join University College and the Royal Institute of Translation. The politics of this imperial Britain are almost precisely the same as in our history, but one of the engines is profoundly different. This world has magic. If words from two different languages are engraved on a metal bar (silver is best), the meaning and nuance lost in translation becomes magical power. With a careful choice of translation pairs, and sometimes additional help from other related words and techniques, the silver bar becomes a persistent spell. Britain's industrial revolution is in overdrive thanks to the country's vast stores of silver and the applied translation prowess of Babel. This means Babel is also the only part of very racist Oxford that accepts non-white students and women. They need translators (barely) more than they care about maintaining social hierarchy; translation pairs only work when the translator is fluent in both languages. The magic is also stronger when meanings are more distinct, which is creating serious worries about classical and European languages. Those are still the bulk of Babel's work, but increased trade and communication within Europe is eroding the meaning distinctions and thus the amount of magical power. More remote languages, such as Chinese and Urdu, are full of untapped promise that Britain's colonial empire wants to capture. Professor Lowell, Robin's dubious benefactor, is a specialist in Chinese languages; Robin is a potential tool for his plans. As Robin discovers shortly after arriving in Oxford, he is not the first of Lowell's tools. His predecessor turned against Babel and is trying to break its chokehold on translation magic. He wants Robin to help. This is one of those books that is hard to review because it does some things exceptionally well and other things that did not work for me. It's not obvious if the latter are flaws in the book or a mismatch between book and reader (or, frankly, flaws in the reader). I'll try to explain as best I can so that you can draw your own conclusions. First, this is one of the all-time great magical system hooks. The way words are tapped for power is fully fleshed out and exceptionally well-done. Kuang is a professional translator, which shows in the attention to detail on translation pairs. I think this is the best-constructed and explained word-based magic system I've read in fantasy. Many word-based systems treat magic as its own separate language that is weirdly universal. Here, Kuang does the exact opposite, and the result is immensely satisfying. A fantasy reader may expect exploration of this magic system to be the primary point of the book, however, and this is not the case. It is an important part of the book, and its implications are essential to the plot resolution, but this is not the type of fantasy novel where the plot is driven by character exploration of the magic system. The magic system exists, the characters use it, and we do get some crunchy details, but the heart of the book is elsewhere. If you were expecting the typical relationship of a fantasy novel to its magic system, you may get a bit wrong-footed. Similarly, this is historical fantasy, but it is the type of historical fantasy where the existence of magic causes no significant differences. For some people, this is a pet peeve; personally, I don't mind that choice in the abstract, but some of the specifics bugged me. The villains of this book assert that any country could have done what Britain did in developing translation magic, and thus their hoarding of it is not immoral. They are obviously partly lying (this is a classic justification for imperialism), but it's not clear from the book how they are lying. Technologies (and magic here works like a technology) tend to concentrate power when they require significant capital investment, and tend to dilute power when they are portable and easy to teach. Translation magic feels like the latter, but its effect in the book is clearly the former, and I was never sure why. England is not an obvious choice to be a translation superpower. Yes, it's a colonial empire, but India, southeast Asia, and most certainly Africa (the continent largely not appearing in this book) are home to considerably more languages from more wildly disparate families than western Europe. Translation is not a peculiarly European idea, and this magic system does not seem hard to stumble across. It's not clear why England, and Oxford in particular, is so dramatically far ahead. There is some sign that Babel is keeping the mechanics of translation magic secret, but that secret has leaked, seems easy to develop independently, and is simple enough that a new student can perform basic magic with a few hours of instruction. This does not feel like the kind of power that would be easy to concentrate, let alone to the extreme extent required by the last quarter of this book. The demand for silver as a base material for translation magic provides a justification for mercantilism that avoids the confusing complexities of currency economics in our actual history, so fine, I guess, but it was a bit disappointing for this great of an idea for a magic system to have this small of an impact on politics. I'll come to the actual thrust of this book in a moment, but first something else Babel does exceptionally well: dark academia. The remainder of Robin's cohort at Oxford is Remy, a dark-skinned Muslim from Calcutta; Victoire, a Haitian woman raised in France; and Letty, the daughter of a British admiral. All of them are non-white except Letty, and Letty and Victoire additionally have to deal with the blatant sexism of the time. (For example, they have to live several miles from Oxford because women living near the college would be a "distraction.") The interpersonal dynamics between the four are exceptionally well done. Kuang captures the dislocation of going away to college, the unsettled life upheaval that makes it both easy and vital to form suddenly tight friendships, and the way that the immense pressure from classes and exams leaves one so devoid of spare emotional capacity that those friendships become both unbreakable and badly strained. Robin and Remy almost immediately become inseparable in that type of college friendship in which profound trust and constant companionship happen first and learning about the other person happens afterwards. It's tricky to talk about this without spoilers, but one of the things Kuang sets up with this friend group is a pointed look at intersectionality. Babel has gotten a lot of positive review buzz, and I think this is one of the reasons why. Kuang does not pass over or make excuses for characters in a place where many other books do. This mostly worked for me, but with a substantial caveat that I think you may want to be aware of before you dive into this book. Babel is set in the 1830s, but it is very much about the politics of 2022. That does not necessarily mean that the politics are off for the 1830s; I haven't done the research to know, and it's possible I'm seeing the Tiffany problem (Jo Walton's observation that Tiffany is a historical 12th century women's name, but an author can't use it as a medieval name because readers think it sounds too modern). But I found it hard to shake the feeling that the characters make sense of their world using modern analytical frameworks of imperialism, racism, sexism, and intersectional feminism, although without using modern terminology, and characters from the 1830s would react somewhat differently. This is a valid authorial choice; all books are written for the readers of the time when they're published. But as with magical systems that don't change history, it's a pet peeve for some readers. If that's you, be aware that's the feel I got from it. The true center of this book is not the magic system or the history. It's advertised directly in the title the necessity of violence although it's not until well into the book before the reader knows what that means. This is a book about revolution, what revolution means, what decisions you have to make along the way, how the personal affects the political, and the inadequacy of reform politics. It is hard, uncomfortable, and not gentle on its characters. The last quarter of this book was exceptional, and I understand why it's getting so much attention. Kuang directly confronts the desire for someone else to do the necessary work, the hope that surely the people with power will see reason, and the feeling of despair when there are no good plans and every reason to wait and do nothing when atrocities are about to happen. If you are familiar with radical politics, these aren't new questions, but this is not the sort of thing that normally shows up in fantasy. It does not surprise me that Babel struck a nerve with readers a generation or two younger than me. It captures that heady feeling on the cusp of adulthood when everything is in flux and one is assembling an independent politics for the first time. Once I neared the end of the book, I could not put it down. The ending is brutal, but I think it was the right ending for this book. There are two things, though, that I did not like about the political arc. The first is that Victoire is a much more interesting character than Robin, but is sidelined for most of the book. The difference of perspectives between her and Robin is the heart of what makes the end of this book so good, and I wish that had started 300 pages earlier. Or, even better, I wish Victoire has been the protagonist; I liked Robin, but he's a very predictable character for most of the book. Victoire is not; even the conflicts she had earlier in the book, when she didn't get much attention in the story, felt more dynamic and more thoughtful than Robin's mix of guilt and anxiety. The second is that I wish Kuang had shown more of Robin's intellectual evolution. All of the pieces of why he makes the decisions that he does are present in this book, and Kuang shows his emotional state (sometimes in agonizing detail) at each step, but the sense-making, the development of theory and ideology beneath the actions, is hinted at but not shown. This is a stylistic choice with no one right answer, but it felt odd because so much of the rest of the plot is obvious and telegraphed. If the reader shares Robin's perspective, I think it's easy to fill in the gaps, but it felt odd to read Robin giving clearly thought-out political analyses at the end of the book without seeing the hashing-out and argument with friends required to develop those analyses. I felt like I had to do a lot of heavy lifting as the reader, work that I wish had been done directly by the book. My final note about this book is that I found much of it extremely predictable. I think that's part of why reviewers describe it as accessible and easy to read; accessibility and predictability can be two sides of the same coin. Kuang did not intend for this book to be subtle, and I think that's part of the appeal. But very few of Robin's actions for the first three-quarters of the book surprised me, and that's not always the reading experience I want. The end of the book is different, and I therefore found it much more gripping, but it takes a while to get there. Babel is, for better or worse, the type of fantasy where the politics, economics, and magic system exist primarily to justify the plot the author wanted. I don't think the societal position of the Institute of Translation that makes the ending possible is that believable given the nature of the technology in question and the politics of the time, and if you are inclined to dig into the specifics of the world-building, I think you will find it frustrating. Where it succeeds brilliantly is in capturing the social dynamics of hothouse academic cohorts, and in making a sharp and unfortunately timely argument about the role of violence in political change, in a way that the traditionally conservative setting of fantasy rarely does. I can't say Babel blew me away, but I can see why others liked it so much. If I had to guess, I'd say that the closer one is in age to the characters in the book and to that moment of political identity construction, the more it's likely to appeal. Rating: 7 out of 10

Russ Allbery: Review: The Last Hero

Review: The Last Hero, by Terry Pratchett
Illustrator: Paul Kidby
Series: Discworld #27
Publisher: Harper
Copyright: 2001, 2002
ISBN: 0-06-050777-2
Format: Graphic novel
Pages: 176
The Last Hero is the 27th Discworld novel and part of the Rincewind subseries. This is something of a sequel to Interesting Times and relies heavily on the cast that was built up in previous books. It's not a good place to start with the series. At last, the rare Rincewind novel that I enjoyed. It helps that Rincewind is mostly along for the ride. Cohen the Barbarian and his band of elderly heroes have decided they're tired of enjoying their spoils and are going on a final adventure. They're going to return fire to the gods, in the form of a giant bomb. The wizards in Ankh-Morpork get wind of this and realize that an explosion at the Hub where the gods live could disrupt the magical field of the entire Disc, effectively destroying it. The only hope seems to be to reach Cori Celesti before Cohen and head him off, but Cohen is already almost there. Enter Lord Vetinari, who has Leonard of Quirm design a machine that will get them there in time by slingshotting under the Disc itself. First off, let me say how much I love the idea of returning fire to the gods with interest. I kind of wish Pratchett had done more with their motivations, but I was laughing about that through the whole book. Second, this is the first of the illustrated Discworld books that I've read in the intended illustrated form (I read the paperback version of Eric), and this book is gorgeous. I enjoyed Paul Kidby's art far more than I had expected to. His style what I will call, for lack of better terminology due to my woeful art education, "highly detailed caricature." That's not normally a style that clicks with me, but it works incredibly well for Discworld. The Last Hero is richly illustrated, with some amount of art, if only subtle background behind the text, on nearly every page. There are several two-page spreads, but oddly I thought those (including the parody of The Scream on the cover) were the worst art of the book. None of them did much for me. The best art is in the figure studies and subtle details: Leonard of Quirm's beautiful calligraphy, his numerous sketches, the labeled illustration of the controls of the flying machine, and the portraits of Cohen's band and the people they encounter. The edition I got is printed on lovely, thick glossy paper, and the subtle art texture behind the writing makes this book a delight to read. I'm not sure if, like Eric, this book comes in other editions, but if so, I highly recommend getting or finding the high-quality illustrated edition for the best reading experience. The plot, like a lot of the Rincewind books, doesn't amount to much, but I enjoyed the mission to intercept Cohen. Leonard of Quirm is a great character, and the slow revelation of his flying machine design (which I will not spoil) is a delightful combination of Leonardo da Vinci parody, Discworld craziness, and NASA homage. Also, the Librarian is involved, which always improves a Discworld book. (The Luggage, sadly, is not; I would have liked to have seen a richly-illustrated story about it, but it looks like I'll have to find the illustrated version of Eric for that.) There is one of Pratchett's philosophical subtexts here, about heroes and stories and what it means for your story to live on. To be honest, it didn't grab me; it's mostly subtext, and this particular set of characters weren't quite introspective enough to make the philosophy central to the story. Also, I was perhaps too sympathetic to Cohen's goals, and thus not very interested in anyone successfully stopping him. But I had a lot more fun with this one than I usually do with Rincewind books, helped considerably by the illustrations. If you've been skipping Rincewind books in your Discworld read-through and have access to the illustrated edition of The Last Hero, consider making an exception for this one. Followed by The Amazing Maurice and His Educated Rodents in publication order and, thematically, by Unseen Academicals. Rating: 7 out of 10

Russ Allbery: Review: Circe

Review: Circe, by Madeline Miller
Publisher: Little, Brown and Company
Copyright: April 2018
Printing: 2020
ISBN: 0-316-55633-5
Format: Kindle
Pages: 421
Circe is the story of the goddess Circe, best known as a minor character in Homer's Odyssey. Circe was Miller's third book if you count the short novella Galatea. She wrote it after Song of Achilles, a reworking of part of the Iliad, but as with Homer, you do not need to read Song of Achilles first. You will occasionally see Circe marketed or reviewed as a retelling of the Odyssey, but it isn't in any meaningful sense. Odysseus doesn't make an appearance until nearly halfway through the book, and the material directly inspired by the Odyssey is only about a quarter of the book. There is nearly as much here from the Telegony, a lost ancient Greek epic poem that we know about only from summaries by later writers and which picks up after the end of the Odyssey. What this is, instead, is Circe's story, starting with her childhood in the halls of Helios, the Titan sun god and her father. She does not have a happy childhood; her voice is considered weak by the gods (Homer describes her as having "human speech"), and her mother and elder siblings are vicious and cruel. Her father is high in the councils of the Titans, who have been overthrown by Zeus and the other Olympians. She is in awe of him and sits at his feet to observe his rule, but he's a petty tyrant who cares very little about her. Her only true companion is her brother Ae tes. The key event of the early book comes when Prometheus is temporarily chained in Helios's halls after stealing fire from the gods and before Zeus passes judgment on him. A young Circe brings him something to drink and has a brief conversation with him. That's the spark for one of the main themes of this book: Circe slowly developing a conscience and empathy, neither of which are common among Miller's gods. But it's still a long road from there to her first meeting with Odysseus. One of the best things about this book is the way that Miller unravels the individual stories of Greek myth and weaves them into a chronological narrative of Circe's life. Greek mythology is mostly individual stories, often contradictory and with only a loose chronology, but Miller pulls together all the ones that touch on Circe's family and turns them into a coherent history. This is not easy to do, and she makes it feel effortless. We get a bit of Jason and Medea (Jason is as dumb as a sack of rocks, and Circe can tell there's already something not right with Medea), the beginnings of the story of Theseus and Ariadne, and Daedalus (one of my favorite characters in the book) with his son Icarus, in addition to the stories more directly associated with Circe (a respinning of Glaucus and Scylla from Ovid's Metamorphoses that makes Circe more central). By the time Odysseus arrives on Circe's island, this world feels rich and full of history, and Circe has had a long and traumatic history that has left her suspicious and hardened. If you know some Greek mythology already, seeing it deftly woven into this new shape is a delight, but Circe may be even better if this is your first introduction to some of these stories. There are pieces missing, since Circe only knows the parts she's present for or that someone can tell her about later, but what's here is vivid, easy to follow, and recast in a narrative structure that's more familiar to modern readers. Miller captures the larger-than-life feel of myth while giving the characters an interiority and comprehensible emotional heft that often gets summarized out of myth retellings or lost in translation from ancient plays and epics, and she does it without ever calling the reader's attention to the mechanics. The prose, similarly, is straightforward and clear, getting out of the way of the story but still providing a sense of place and description where it's needed. This book feels honed, edited and streamlined until it maintains an irresistible pace. There was only one place where I felt like the story dragged (the raising of Telegonus), and then mostly because it's full of anger and anxiety and frustration and loss of control, which is precisely what Miller was trying to achieve. The rest of the book pulls the reader relentlessly forward while still delivering moments of beauty or sharp observation.
My house was crowded with some four dozen men, and for the first time in my life, I found myself steeped in mortal flesh. Those frail bodies of theirs took relentless attention, food and drink, sleep and rest, the cleaning of limbs and fluxes. Such patience mortals must have, I thought, to drag themselves through it hour after hour.
I did not enjoy reading about Telegonus's childhood (it was too stressful; I don't like reading about characters fighting in that way), but apart from that, the last half of this book is simply beautiful. By the time Odysseus arrives, we're thoroughly in Circe's head and agree with all of the reasons why he might receive a chilly reception. Odysseus talks the readers around at the same time that he talks Circe around. It's one of the better examples of writing intelligent, observant, and thoughtful characters that I have read recently. I also liked that Odysseus has real flaws, and those flaws do not go away even when the reader warms to him. I'll avoid saying too much about the very end of the book to avoid spoilers (insofar as one can spoil Greek myth, but the last quarter of the book is where I think Miller adds the most to the story). I'll just say that both Telemachus and Penelope are exceptional characters while being nothing like Circe or Odysseus, and watching the characters tensely circle each other is a wholly engrossing reading experience. It's a much more satisfying ending than the Telegony traditionally gets (although I have mixed feelings about the final page). I've mostly talked about the Greek mythology part of Circe, since that's what grabbed me the most, but it's quite rightly called a feminist retelling and it lives up to that label with the same subtlety and skill that Miller brings to the prose and characterization. The abusive gender dynamics of Greek myth are woven into the narrative so elegantly you'd think they were always noted in the stories. It is wholly satisfying to see Circe come into her own power in a defiantly different way than that chosen by her mother and her sister. She spends the entire book building an inner strength and sense of herself that allows her to defend her own space and her own identity, and the payoff is pure delight. But even better are the quiet moments between her and Penelope.
"I am embarrassed to ask this of you, but I did not bring a black cloak with me when we left. Do you have one I might wear? I would mourn for him." I looked at her, as vivid in my doorway as the moon in the autumn sky. Her eyes held mine, gray and steady. It is a common saying that women are delicate creatures, flowers, eggs, anything that may be crushed in a moment s carelessness. If I had ever believed it, I no longer did. "No," I said. "But I have yarn, and a loom. Come."
This is as good as everyone says it is. Highly recommended for the next time you're in the mood for a myth retelling. Rating: 8 out of 10
