Russ Allbery: Review: Nation

Review: Nation, by Terry Pratchett
Publisher: Harper
Copyright: 2008
Printing: 2009
ISBN: 0-06-143303-9
Format: Trade paperback
Pages: 369
Nation is a stand-alone young adult fantasy novel. It was published in the gap between Discworld novels Making Money and Unseen Academicals. Nation starts with a plague. The Russian influenza has ravaged Britain, including the royal family. The next in line to the throne is off on a remote island and must be retrieved and crowned as soon as possible, or an obscure provision in Magna Carta will cause no end of trouble. The Cutty Wren is sent on this mission, carrying the Gentlemen of Last Resort. Then comes the tsunami. In the midst of fire raining from the sky and a wave like no one has ever seen, Captain Roberts tied himself to the wheel of the Sweet Judy and steered it as best he could, straight into an island. The sole survivor of the shipwreck: one Ermintrude Fanshaw, daughter of the governor of some British island possessions. Oh, and a parrot. Mau was on the Boys' Island when the tsunami came, going through his rite of passage into manhood. He was to return to the Nation the next morning and receive his tattoos and his adult soul. He survived in a canoe. No one else in the Nation did. Terry Pratchett considered Nation to be his best book. It is not his best book, at least in my opinion; it's firmly below the top tier of Discworld novels, let alone Night Watch. It is, however, an interesting and enjoyable book that tackles gods and religion with a sledgehammer rather than a knife. It's also very, very dark and utterly depressing at the start, despite a few glimmers of Pratchett's humor. Mau is the main protagonist at first, and the book opens with everyone he cares about dying. This is the place where I thought Pratchett diverged the most from his Discworld style: in Discworld, I think most of that would have been off-screen, but here we follow Mau through the realization, the devastation, the disassociation, the burials at sea, the thoughts of suicide, and the complete upheaval of everything he thought he was or was about to become. I found the start of this book difficult to get through. The immediate transition into potentially tragic misunderstandings between Mau and Daphne (as Ermintrude names herself once there is no one to tell her not to) didn't help. As I got farther into the book, though, I warmed to it. The best parts early on are Daphne's baffled but scientific attempts to understand Mau's culture and her place in it. More survivors arrive, and they start to assemble a community, anchored in large part by Mau's stubborn determination to do what's right even though he's lost all of his moorings. That community eventually re-establishes contact with the rest of the world and the opening plot about the British monarchy, but not before Daphne has been changed profoundly by being part of it. I think Pratchett worked hard at keeping Mau's culture at the center of the story. It's notable that the community that reforms over the course of the book essentially follows the patterns of Mau's lost Nation and incorporates Daphne into it, rather than (as is so often the case) the other way around. The plot itself is fiercely anti-colonial in a way that mostly worked. Still, though, it's a quasi-Pacific-island culture written by a white British man, and I had some qualms. Pratchett quite rightfully makes it clear in the afterward that this is an alternate world and Mau's culture is not a real Pacific island culture. However, that also means that its starkly gender-essentialist nature was a free choice, rather than one based on some specific culture, and I found that choice somewhat off-putting. The religious rituals are all gendered, the dwelling places are gendered, and one's entire life course in Mau's world seems based on binary classification as a man or a woman. Based on Pratchett's other books, I assume this was more an unfortunate default than a deliberate choice, but it's still a choice he could have avoided. The end of this book wrestles directly with the relative worth of Mau's culture versus that of the British. I liked most of this, but the twists that Pratchett adds to avoid the colonialist results we saw in our world stumble partly into the trap of making Mau's culture valuable by British standards. (I'm being a bit vague here to avoid spoilers.) I think it is very hard to base this book on a different set of priorities and still bring the largely UK, US, and western European audience along, so I don't blame Pratchett for failing to do it, but I'm a bit sad that the world still revolved around a British axis. This felt quite similar to Discworld to me in its overall sensibilities, but with the roles of moral philosophy and humor reversed. Discworld novels usually start with some larger-than-life characters and an absurd plot, and then the moral philosophy sneaks up behind you when you're not looking and hits you over the head. Nation starts with the moral philosophy: Mau wrestles with his gods and the problem of evil in a way that reminded me of Job, except with a far different pantheon and rather less tolerance for divine excuses on the part of the protagonist. It's the humor, instead, that sneaks up on you and makes you laugh when the plot is a bit too much. But the mix arrives at much the same place: the absurd hand-in-hand with the profound, and all seen from an angle that makes it a bit easier to understand. I'm not sure I would recommend Nation as a good place to start with Pratchett. I felt like I benefited from having read a lot of Discworld to build up my willingness to trust where Pratchett was going. But it has the quality of writing of late Discworld without the (arguable) need to read 25 books to understand all of the backstory. Regardless, recommended, and you'll never hear Twinkle Twinkle Little Star in quite the same way again. Rating: 8 out of 10

Bastian Venthur: Help needed: creating a WSDL file to interact with debbugs

I am upstream and Debian package maintainer of python-debianbts, which is a Python library that allows for querying Debian s Bug Tracking System (BTS). python-debianbts is used by reportbug, the standard tool to report bugs in Debian, and therefore the glue between the reportbug and the BTS. debbugs, the software that powers Debian s BTS, provides a SOAP interface for querying the BTS. Unfortunately, SOAP is not a very popular protocol anymore, and I m facing the second migration to another underlying SOAP library as they continue to become unmaintained over time. Zeep, the library I m currently considering, requires a WSDL file in order to work with a SOAP service, however, debbugs does not provide one. Since I m not familiar with WSDL, I need help from someone who can create a WSDL file for debbugs, so I can migrate python-debianbts away from pysimplesoap to zeep. How did we get here? Back in the olden days, reportbug was querying the BTS by parsing its HTML output. While this worked, it tightly coupled the user-facing presentation of the BTS with critical functionality of the bug reporting tool. The setup was fragile, prone to breakage, and did not allow changing anything in the BTS frontend for fear of breaking reportbug itself. In 2007, I started to work on reportbug-ng, a user-friendly alternative to reportbug, targeted at users not comfortable using the command line. Early on, I decided to use the BTS SOAP interface instead of parsing HTML like reportbug did. 2008, I extracted the code that dealt with the BTS into a separate Python library, and after some collaboration with the reportbug maintainers, reportbug adopted python-debianbts in 2011 and has used it ever since. 2015, I was working on porting python-debianbts to Python 3. During that process, it turned out that its major dependency, SoapPy was pretty much unmaintained for years and blocking the Python3 transition. Thanks to the help of Gaetano Guerriero, who ported python-debianbts to pysimplesoap, the migration was unblocked and could proceed. In 2024, almost ten years later, pysimplesoap seems to be unmaintained as well, and I have to look again for alternatives. The most promising one right now seems to be zeep. Unfortunately, zeep requires a WSDL file for working with a SOAP service, which debbugs does not provide. How can you help? reportbug (and thus python-debianbts) is used by thousands of users and I have a certain responsibility to keep things working properly. Since I simply don t know enough about WSDL to create such a file for debbugs myself, I m looking for someone who can help me with this task. If you re familiar with SOAP, WSDL and optionally debbugs, please get in touch with me. I don t speak Pearl, so I m not really able to read debbugs code, but I do know some things about the SOAP requests and replies due to my work on python-debianbts, so I m sure we can work something out. There is a WSDL file for a debbugs version used by GNU, but I don t think it s official and it currently does not work with zeep. It may be a good starting point, though. The future of debbugs API While we can probably continue to support debbugs SOAP interface for a while, I don t think it s very sustainable in the long run. A simpler, well documented REST API that returns JSON seems more appropriate nowadays. The queries and replies that debbugs currently supports are simple enough to design a REST API with JSON around it. The benefit would be less complex libraries on the client side and probably easier maintainability on the server side as well. debbugs maintainer seemed to be in agreement with this idea back in 2018. I created an attempt to define a new API (HTML render), but somehow we got stuck and no progress has been made since then. I m still happy to help shaping such an API for debbugs, but I can t really implement anything in debbugs itself, as it is written in Perl, which I m not familiar with.

Thomas Koch: Minimal overhead VMs with Nix and MicroVM

Posted on March 17, 2024
Joachim Breitner wrote about a Convenient sandboxed development environment and thus reminded me to blog about MicroVM. I ve toyed around with it a little but not yet seriously used it as I m currently not coding. MicroVM is a nix based project to configure and run minimal VMs. It can mount and thus reuse the hosts nix store inside the VM and thus has a very small disk footprint. I use MicroVM on a debian system using the nix package manager. The MicroVM author uses the project to host production services. Otherwise I consider it also a nice way to learn about NixOS after having started with the nix package manager and before making the big step to NixOS as my main system. The guests root filesystem is a tmpdir, so one must explicitly define folders that should be mounted from the host and thus be persistent across VM reboots. I defined the VM as a nix flake since this is how I started from the MicroVM projects example:

    in  
      packages.$ system .default = nixosConfiguration.config.microvm.declaredRunner;
     ;
 
I start the microVM with a templated systemd user service:
[Unit]
Description=MicroVM for Haskell development
Requires=microvm-virtiofsd-persistent@.service
After=microvm-virtiofsd-persistent@.service
AssertFileNotEmpty=%h/.local/share/microvm/vms/%i/flake/flake.nix
[Service]
Type=forking
ExecStartPre=/usr/bin/sh -c "[ /nix/var/nix/db/db.sqlite -ot %h/.local/share/microvm/nix-store-db-dump ]   nix-store --dump-db >%h/.local/share/microvm/nix-store-db-dump"
ExecStartPre=ln -f -t %h/.local/share/microvm/vms/%i/persistent/ %h/.local/share/microvm/nix-store-db-dump
ExecStartPre=-%h/.local/state/nix/profile/bin/tmux new -s microvm -d
ExecStart=%h/.local/state/nix/profile/bin/tmux new-window -t microvm: -n "%i" "exec %h/.local/state/nix/profile/bin/nix run --impure %h/.local/share/microvm/vms/%i/flake"
The above service definition creates a dump of the hosts nix store db so that it can be imported in the guest. This is necessary so that the guest can actually use what is available in /nix/store. There is an effort for an overlayed nix store that would be preferable to this hack. Finally the microvm is started inside a tmux session named microvm . This way I can use the VM with SSH or through the console and also access the qemu console. And for completeness the virtiofsd service:
[Unit]
Description=serve host persistent folder for dev VM
AssertPathIsDirectory=%h/.local/share/microvm/vms/%i/persistent
[Service]
ExecStart=%h/.local/state/nix/profile/bin/virtiofsd \
 --socket-path=$ XDG_RUNTIME_DIR /microvm-%i-persistent \
 --shared-dir=%h/.local/share/microvm/vms/%i/persistent \

Thomas Koch: Chromium gtk-filechooser preview size

Posted on January 9, 2024
I wanted to report this issue in chromiums issue tracker, but it gave me:
Something went wrong, please try again later.
Ok, then at least let me reply to this askubuntu question. But my attempt to signup with my launchpad account gave me:
Launchpad Login Failed. Please try logging in again.
I refrain from commenting on this to not violate some code of conduct. So this is what I wanted to write:
GTK file chooser image preview size should be configurable The file chooser that appears when uploading a file (e.g. an image to Google Fotos) learned to show a preview in issue 15500. The preview image size is hard coded to 256x512 in kPreviewWidth and kPreviewHeight in ui/gtk/select_file_dialog_linux_gtk.cc. Please make the size configurable. On high DPI screens the images are too small to be of much use.
Yes, I should not use chromium anymore.

John Goerzen: Facebook is Censoring Stories about Climate Change and Illegal Raid in Marion, Kansas

It is, sadly, not entirely surprising that Facebook is censoring articles critical of Meta. The Kansas Reflector published an artical about Meta censoring environmental articles about climate change deeming them too controversial . Facebook then censored the article about Facebook censorship, and then after an independent site published a copy of the climate change article, Facebook censored it too. The CNN story says Facebook apologized and said it was a mistake and was fixing it. Color me skeptical, because today I saw this: Yes, that s right: today, April 6, I get a notification that they removed a post from August 12. The notification was dated April 4, but only showed up for me today. I wonder why my post from August 12 was fine for nearly 8 months, and then all of a sudden, when the same website runs an article critical of Facebook, my 8-month-old post is a problem. Hmm. Riiiiiight. Cybersecurity. This isn t even the first time they ve done this to me. On September 11, 2021, they removed my post about the social network Mastodon (click that link for screenshot). A post that, incidentally, had been made 10 months prior to being removed. While they ultimately reversed themselves, I subsequently wrote Facebook s Blocking Decisions Are Deliberate Including Their Censorship of Mastodon. That this same pattern has played out a second time again with something that is a very slight challenege to Facebook seems to validate my conclusion. Facebook lets all sort of hateful garbage infest their site, but anything about climate change or their own censorship gets removed, and this pattern persists for years. There s a reason I prefer Mastodon these days. You can find me there as @jgoerzen@floss.social. So. I ve written this blog post. And then I m going to post it to Facebook. Let s see if they try to censor me for a third time. Bring it, Facebook.

Bits from Debian: Bits from the DPL

Dear Debianites This morning I decided to just start writing Bits from DPL and send whatever I have by 18:00 local time. Here it is, barely proof read, along with all it's warts and grammar mistakes! It's slightly long and doesn't contain any critical information, so if you're not in the mood, don't feel compelled to read it! Get ready for a new DPL! Soon, the voting period will start to elect our next DPL, and my time as DPL will come to an end. Reading the questions posted to the new candidates on debian-vote, it takes quite a bit of restraint to not answer all of them myself, I think I can see how that aspect contributed to me being reeled in to running for DPL! In total I've done so 5 times (the first time I ran, Sam was elected!). Good luck to both Andreas and Sruthi, our current DPL candidates! I've already started working on preparing handover, and there's multiple request from teams that have came in recently that will have to wait for the new term, so I hope they're both ready to hit the ground running! Things that I wish could have gone better Communication Recently, I saw a t-shirt that read:
Adulthood is saying, 'But after this week things will slow down a bit' over and over until you die.
I can relate! With every task, crisis or deadline that appears, I think that once this is over, I'll have some more breathing space to get back to non-urgent, but important tasks. "Bits from the DPL" was something I really wanted to get right this last term, and clearly failed spectacularly. I have two long Bits from the DPL drafts that I never finished, I tend to have prioritised problems of the day over communication. With all the hindsight I have, I'm not sure which is better to prioritise, I do rate communication and transparency very highly and this is really the top thing that I wish I could've done better over the last four years. On that note, thanks to people who provided me with some kind words when I've mentioned this to them before. They pointed out that there are many other ways to communicate and be in touch with the community, and they mentioned that they thought that I did a good job with that. Since I'm still on communication, I think we can all learn to be more effective at it, since it's really so important for the project. Every time I publicly spoke about us spending more money, we got more donations. People out there really like to see how we invest funds in to Debian, instead of just making it heap up. DSA just spent a nice chunk on money on hardware, but we don't have very good visibility on it. It's one thing having it on a public line item in SPI's reporting, but it would be much more exciting if DSA could provide a write-up on all the cool hardware they're buying and what impact it would have on developers, and post it somewhere prominent like debian-devel-announce, Planet Debian or Bits from Debian (from the publicity team). I don't want to single out DSA there, it's difficult and affects many other teams. The Salsa CI team also spent a lot of resources (time and money wise) to extend testing on AMD GPUs and other AMD hardware. It's fantastic and interesting work, and really more people within the project and in the outside world should know about it! I'm not going to push my agendas to the next DPL, but I hope that they continue to encourage people to write about their work, and hopefully at some point we'll build enough excitement in doing so that it becomes a more normal part of our daily work. Founding Debian as a standalone entity This was my number one goal for the project this last term, which was a carried over item from my previous terms. I'm tempted to write everything out here, including the problem statement and our current predicaments, what kind of ground work needs to happen, likely constitutional changes that need to happen, and the nature of the GR that would be needed to make such a thing happen, but if I start with that, I might not finish this mail. In short, I 100% believe that this is still a very high ranking issue for Debian, and perhaps after my term I'd be in a better position to spend more time on this (hmm, is this an instance of "The grass is always better on the other side", or "Next week will go better until I die?"). Anyway, I'm willing to work with any future DPL on this, and perhaps it can in itself be a delegation tasked to properly explore all the options, and write up a report for the project that can lead to a GR. Overall, I'd rather have us take another few years and do this properly, rather than rush into something that is again difficult to change afterwards. So while I very much wish this could've been achieved in the last term, I can't say that I have any regrets here either. My terms in a nutshell COVID-19 and Debian 11 era My first term in 2020 started just as the COVID-19 pandemic became known to spread globally. It was a tough year for everyone, and Debian wasn't immune against its effects either. Many of our contributors got sick, some have lost loved ones (my father passed away in March 2020 just after I became DPL), some have lost their jobs (or other earners in their household have) and the effects of social distancing took a mental and even physical health toll on many. In Debian, we tend to do really well when we get together in person to solve problems, and when DebConf20 got cancelled in person, we understood that that was necessary, but it was still more bad news in a year we had too much of it already. I can't remember if there was ever any kind of formal choice or discussion about this at any time, but the DebConf video team just kind of organically and spontaneously became the orga team for an online DebConf, and that lead to our first ever completely online DebConf. This was great on so many levels. We got to see each other's faces again, even though it was on screen. We had some teams talk to each other face to face for the first time in years, even though it was just on a Jitsi call. It had a lasting cultural change in Debian, some teams still have video meetings now, where they didn't do that before, and I think it's a good supplement to our other methods of communication. We also had a few online Mini-DebConfs that was fun, but DebConf21 was also online, and by then we all developed an online conference fatigue, and while it was another good online event overall, it did start to feel a bit like a zombieconf and after that, we had some really nice events from the Brazillians, but no big global online community events again. In my opinion online MiniDebConfs can be a great way to develop our community and we should spend some further energy into this, but hey! This isn't a platform so let me back out of talking about the future as I see it... Despite all the adversity that we faced together, the Debian 11 release ended up being quite good. It happened about a month or so later than what we ideally would've liked, but it was a solid release nonetheless. It turns out that for quite a few people, staying inside for a few months to focus on Debian bugs was quite productive, and Debian 11 ended up being a very polished release. During this time period we also had to deal with a previous Debian Developer that was expelled for his poor behaviour in Debian, who continued to harass members of the Debian project and in other free software communities after his expulsion. This ended up being quite a lot of work since we had to take legal action to protect our community, and eventually also get the police involved. I'm not going to give him the satisfaction by spending too much time talking about him, but you can read our official statement regarding Daniel Pocock here: https://www.debian.org/News/2021/20211117 In late 2021 and early 2022 we also discussed our general resolution process, and had two consequent votes to address some issues that have affected past votes: In my first term I addressed our delegations that were a bit behind, by the end of my last term all delegation requests are up to date. There's still some work to do, but I'm feeling good that I get to hand this over to the next DPL in a very decent state. Delegation updates can be very deceiving, sometimes a delegation is completely re-written and it was just 1 or 2 hours of work. Other times, a delegation updated can contain one line that has changed or a change in one team member that was the result of days worth of discussion and hashing out differences. I also received quite a few requests either to host a service, or to pay a third-party directly for hosting. This was quite an admin nightmare, it either meant we had to manually do monthly reimbursements to someone, or have our TOs create accounts/agreements at the multiple providers that people use. So, after talking to a few people about this, we founded the DebianNet team (we could've admittedly chosen a better name, but that can happen later on) for providing hosting at two different hosting providers that we have agreement with so that people who host things under debian.net have an easy way to host it, and then at the same time Debian also has more control if a site maintainer goes MIA. More info: https://wiki.debian.org/Teams/DebianNet You might notice some Openstack mentioned there, we had some intention to set up a Debian cloud for hosting these things, that could also be used for other additional Debiany things like archive rebuilds, but these have so far fallen through. We still consider it a good idea and hopefully it will work out some other time (if you're a large company who can sponsor few racks and servers, please get in touch!) DebConf22 and Debian 12 era DebConf22 was the first time we returned to an in-person DebConf. It was a bit smaller than our usual DebConf - understandably so, considering that there were still COVID risks and people who were at high risk or who had family with high risk factors did the sensible thing and stayed home. After watching many MiniDebConfs online, I also attended my first ever MiniDebConf in Hamburg. It still feels odd typing that, it feels like I should've been at one before, but my location makes attending them difficult (on a side-note, a few of us are working on bootstrapping a South African Debian community and hopefully we can pull off MiniDebConf in South Africa later this year). While I was at the MiniDebConf, I gave a talk where I covered the evolution of firmware, from the simple e-proms that you'd find in old printers to the complicated firmware in modern GPUs that basically contain complete operating systems- complete with drivers for the device their running on. I also showed my shiny new laptop, and explained that it's impossible to install that laptop without non-free firmware (you'd get a black display on d-i or Debian live). Also that you couldn't even use an accessibility mode with audio since even that depends on non-free firmware these days. Steve, from the image building team, has said for a while that we need to do a GR to vote for this, and after more discussion at DebConf, I kept nudging him to propose the GR, and we ended up voting in favour of it. I do believe that someone out there should be campaigning for more free firmware (unfortunately in Debian we just don't have the resources for this), but, I'm glad that we have the firmware included. In the end, the choice comes down to whether we still want Debian to be installable on mainstream bare-metal hardware. At this point, I'd like to give a special thanks to the ftpmasters, image building team and the installer team who worked really hard to get the changes done that were needed in order to make this happen for Debian 12, and for being really proactive for remaining niggles that was solved by the time Debian 12.1 was released. The included firmware contributed to Debian 12 being a huge success, but it wasn't the only factor. I had a list of personal peeves, and as the hard freeze hit, I lost hope that these would be fixed and made peace with the fact that Debian 12 would release with those bugs. I'm glad that lots of people proved me wrong and also proved that it's never to late to fix bugs, everything on my list got eliminated by the time final freeze hit, which was great! We usually aim to have a release ready about 2 years after the previous release, sometimes there are complications during a freeze and it can take a bit longer. But due to the excellent co-ordination of the release team and heavy lifting from many DDs, the Debian 12 release happened 21 months and 3 weeks after the Debian 11 release. I hope the work from the release team continues to pay off so that we can achieve their goals of having shorter and less painful freezes in the future! Even though many things were going well, the ongoing usr-merge effort highlighted some social problems within our processes. I started typing out the whole history of usrmerge here, but it's going to be too long for the purpose of this mail. Important questions that did come out of this is, should core Debian packages be team maintained? And also about how far the CTTE should really be able to override a maintainer. We had lots of discussion about this at DebConf22, but didn't make much concrete progress. I think that at some point we'll probably have a GR about package maintenance. Also, thank you to Guillem who very patiently explained a few things to me (after probably having have to done so many times to others before already) and to Helmut who have done the same during the MiniDebConf in Hamburg. I think all the technical and social issues here are fixable, it will just take some time and patience and I have lots of confidence in everyone involved. UsrMerge wiki page: https://wiki.debian.org/UsrMerge DebConf 23 and Debian 13 era DebConf23 took place in Kochi, India. At the end of my Bits from the DPL talk there, someone asked me what the most difficult thing I had to do was during my terms as DPL. I answered that nothing particular stood out, and even the most difficult tasks ended up being rewarding to work on. Little did I know that my most difficult period of being DPL was just about to follow. During the day trip, one of our contributors, Abraham Raji, passed away in a tragic accident. There's really not anything anyone could've done to predict or stop it, but it was devastating to many of us, especially the people closest to him. Quite a number of DebConf attendees went to his funeral, wearing the DebConf t-shirts he designed as a tribute. It still haunts me when I saw his mother scream "He was my everything! He was my everything!", this was by a large margin the hardest day I've ever had in Debian, and I really wasn't ok for even a few weeks after that and I think the hurt will be with many of us for some time to come. So, a plea again to everyone, please take care of yourself! There's probably more people that love you than you realise. A special thanks to the DebConf23 team, who did a really good job despite all the uphills they faced (and there were many!). As DPL, I think that planning for a DebConf is near to impossible, all you can do is show up and just jump into things. I planned to work with Enrico to finish up something that will hopefully save future DPLs some time, and that is a web-based DD certificate creator instead of having the DPL do so manually using LaTeX. It already mostly works, you can see the work so far by visiting https://nm.debian.org/person/ACCOUNTNAME/certificate/ and replacing ACCOUNTNAME with your Debian account name, and if you're a DD, you should see your certificate. It still needs a few minor changes and a DPL signature, but at this point I think that will be finished up when the new DPL start. Thanks to Enrico for working on this! Since my first term, I've been trying to find ways to improve all our accounting/finance issues. Tracking what we spend on things, and getting an annual overview is hard, especially over 3 trusted organisations. The reimbursement process can also be really tedious, especially when you have to provide files in a certain order and combine them into a PDF. So, at DebConf22 we had a meeting along with the treasurer team and Stefano Rivera who said that it might be possible for him to work on a new system as part of his Freexian work. It worked out, and Freexian funded the development of the system since then, and after DebConf23 we handled the reimbursements for the conference via the new reimbursements site: https://reimbursements.debian.net/ It's still early days, but over time it should be linked to all our TOs and we'll use the same category codes across the board. So, overall, our reimbursement process becomes a lot simpler, and also we'll be able to get information like how much money we've spent on any category in any period. It will also help us to track how much money we have available or how much we spend on recurring costs. Right now that needs manual polling from our TOs. So I'm really glad that this is a big long-standing problem in the project that is being fixed. For Debian 13, we're waving goodbye to the KFreeBSD and mipsel ports. But we're also gaining riscv64 and loongarch64 as release architectures! I have 3 different RISC-V based machines on my desk here that I haven't had much time to work with yet, you can expect some blog posts about them soon after my DPL term ends! As Debian is a unix-like system, we're affected by the Year 2038 problem, where systems that uses 32 bit time in seconds since 1970 run out of available time and will wrap back to 1970 or have other undefined behaviour. A detailed wiki page explains how this works in Debian, and currently we're going through a rather large transition to make this possible. I believe this is the right time for Debian to be addressing this, we're still a bit more than a year away for the Debian 13 release, and this provides enough time to test the implementation before 2038 rolls along. Of course, big complicated transitions with dependency loops that causes chaos for everyone would still be too easy, so this past weekend (which is a holiday period in most of the west due to Easter weekend) has been filled with dealing with an upstream bug in xz-utils, where a backdoor was placed in this key piece of software. An Ars Technica covers it quite well, so I won't go into all the details here. I mention it because I want to give yet another special thanks to everyone involved in dealing with this on the Debian side. Everyone involved, from the ftpmasters to security team and others involved were super calm and professional and made quick, high quality decisions. This also lead to the archive being frozen on Saturday, this is the first time I've seen this happen since I've been a DD, but I'm sure next week will go better! Looking forward It's really been an honour for me to serve as DPL. It might well be my biggest achievement in my life. Previous DPLs range from prominent software engineers to game developers, or people who have done things like complete Iron Man, run other huge open source projects and are part of big consortiums. Ian Jackson even authored dpkg and is now working on the very interesting tag2upload service! I'm a relative nobody, just someone who grew up as a poor kid in South Africa, who just really cares about Debian a lot. And, above all, I'm really thankful that I didn't do anything major to screw up Debian for good. Not unlike learning how to use Debian, and also becoming a Debian Developer, I've learned a lot from this and it's been a really valuable growth experience for me. I know I can't possible give all the thanks to everyone who deserves it, so here's a big big thanks to everyone who have worked so hard and who have put in many, many hours to making Debian better, I consider you all heroes! -Jonathan

Erich Schubert: Do not get Amazon Kids+ or a Fire HD Kids

The Amazon Kids parental controls are extremely insufficient, and I strongly advise against getting any of the Amazon Kids series. The initial permise (and some older reviews) look okay: you can set some time limits, and you can disable anything that requires buying. With the hardware you get one year of the Amazon Kids+ subscription, which includes a lot of interesting content such as books and audio, but also some apps. This seemed attractive: some learning apps, some decent games. Sometimes there seems to be a special Amazon Kids+ edition , supposedly one that has advertisements reduced/removed and no purchasing. However, there are so many things just wrong in Amazon Kids: And, unfortunately, Amazon Kids is full of poor content for kids, such as DIY Fashion Star that I consider to be very dangerous for kids: it is extremely stereotypical, beginning with supposedly female color schemes, model-only body types, and judging people by their clothing (and body). You really thought you could hand-pick suitable apps for your kid on your own? No, you have to identify and remove such contents one by one, with many clicks each, because there is no whitelisting, and no mass-removal (anymore - apparently Amazon removed the workarounds that previously allowed you to mass remove contents). Not with Amazon Kids+, which apparently aims at raising the next generation of zombie customers that buy whatever you tell them to buy. Hence, do not get your kids an Amazon Fire HD tablet!

Matthew Garrett: Digital forgeries are hard

Closing arguments in the trial between various people and Craig Wright over whether he's Satoshi Nakamoto are wrapping up today, amongst a bewildering array of presented evidence. But one utterly astonishing aspect of this lawsuit is that expert witnesses for both sides agreed that much of the digital evidence provided by Craig Wright was unreliable in one way or another, generally including indications that it wasn't produced at the point in time it claimed to be. And it's fascinating reading through the subtle (and, in some cases, not so subtle) ways that that's revealed.

One of the pieces of evidence entered is screenshots of data from Mind Your Own Business, a business management product that's been around for some time. Craig Wright relied on screenshots of various entries from this product to support his claims around having controlled meaningful number of bitcoin before he was publicly linked to being Satoshi. If these were authentic then they'd be strong evidence linking him to the mining of coins before Bitcoin's public availability. Unfortunately the screenshots themselves weren't contemporary - the metadata shows them being created in 2020. This wouldn't fundamentally be a problem (it's entirely reasonable to create new screenshots of old material), as long as it's possible to establish that the material shown in the screenshots was created at that point. Sadly, well.

One part of the disclosed information was an email that contained a zip file that contained a raw database in the format used by MYOB. Importing that into the tool allowed an audit record to be extracted - this record showed that the relevant entries had been added to the database in 2020, shortly before the screenshots were created. This was, obviously, not strong evidence that Craig had held Bitcoin in 2009. This evidence was reported, and was responded to with a couple of additional databases that had an audit trail that was consistent with the dates in the records in question. Well, partially. The audit record included session data, showing an administrator logging into the data base in 2011 and then, uh, logging out in 2023, which is rather more consistent with someone changing their system clock to 2011 to create an entry, and switching it back to present day before logging out. In addition, the audit log included fields that didn't exist in versions of the product released before 2016, strongly suggesting that the entries dated 2009-2011 were created in software released after 2016. And even worse, the order of insertions into the database didn't line up with calendar time - an entry dated before another entry may appear in the database afterwards, indicating that it was created later. But even more obvious? The database schema used for these old entries corresponded to a version of the software released in 2023.

This is all consistent with the idea that these records were created after the fact and backdated to 2009-2011, and that after this evidence was made available further evidence was created and backdated to obfuscate that. In an unusual turn of events, during the trial Craig Wright introduced further evidence in the form of a chain of emails to his former lawyers that indicated he had provided them with login details to his MYOB instance in 2019 - before the metadata associated with the screenshots. The implication isn't entirely clear, but it suggests that either they had an opportunity to examine this data before the metadata suggests it was created, or that they faked the data? So, well, the obvious thing happened, and his former lawyers were asked whether they received these emails. The chain consisted of three emails, two of which they confirmed they'd received. And they received a third email in the chain, but it was different to the one entered in evidence. And, uh, weirdly, they'd received a copy of the email that was submitted - but they'd received it a few days earlier. In 2024.

And again, the forensic evidence is helpful here! It turns out that the email client used associates a timestamp with any attachments, which in this case included an image in the email footer - and the mysterious time travelling email had a timestamp in 2024, not 2019. This was created by the client, so was consistent with the email having been sent in 2024, not being sent in 2019 and somehow getting stuck somewhere before delivery. The date header indicates 2019, as do encoded timestamps in the MIME headers - consistent with the mail being sent by a computer with the clock set to 2019.

But there's a very weird difference between the copy of the email that was submitted in evidence and the copy that was located afterwards! The first included a header inserted by gmail that included a 2019 timestamp, while the latter had a 2024 timestamp. Is there a way to determine which of these could be the truth? It turns out there is! The format of that header changed in 2022, and the version in the email is the new version. The version with the 2019 timestamp is anachronistic - the format simply doesn't match the header that gmail would have introduced in 2019, suggesting that an email sent in 2022 or later was modified to include a timestamp of 2019.

This is by no means the only indication that Craig Wright's evidence may be misleading (there's the whole argument that the Bitcoin white paper was written in LaTeX when general consensus is that it's written in OpenOffice, given that's what the metadata claims), but it's a lovely example of a more general issue.

Our technology chains are complicated. So many moving parts end up influencing the content of the data we generate, and those parts develop over time. It's fantastically difficult to generate an artifact now that precisely corresponds to how it would look in the past, even if we go to the effort of installing an old OS on an old PC and setting the clock appropriately (are you sure you're going to be able to mimic an entirely period appropriate patch level?). Even the version of the font you use in a document may indicate it's anachronistic. I'm pretty good at computers and I no longer have any belief I could fake an old document.

Dirk Eddelbuettel: ciw 0.0.1 on CRAN: New Package!

Happy to share that ciw is now on CRAN! I had tooted a little bit about it, e.g., here. What it provides is a single (efficient) function incoming() which summarises the state of the incoming directories at CRAN. I happen to like having these things at my (shell) fingertips, so it goes along with (still draft) wrapper ciw.r that will be part of the next littler release. For example, when I do this right now as I type this, I see
edd@rob:~$ ciw.r
    Folder                   Name                Time   Size          Age
    <char>                 <char>              <POSc> <char>   <difftime>

edd@rob:~$ 
which is rather compact as CRAN kept busy! This call runs in about (or just over) one second, which includes launching r. Good enough for me. From a well-connected EC2 instance it is about 800ms on the command-line. When I do I from here inside an R session it is maybe 700ms. And doing it over in Europe is faster still. (I am using ping=FALSE for these to omit the default sanity check of can I haz networking? to speed things up. The check adds another 200ms or so.) The function (and the wrapper) offer a ton of options too this is ridiculously easy to do thanks to the docopt package:
edd@rob:~$ ciw.r -x
Usage: ciw.r [-h] [-x] [-a] [-m] [-i] [-t] [-p] [-w] [-r] [-s] [-n] [-u] [-l rows] [-z] [ARG...]

-m --mega           use 'mega' mode of all folders (see --usage)
-i --inspect        visit 'inspect' folder
-t --pretest        visit 'pretest' folder
-p --pending        visit 'pending' folder
-w --waiting        visit 'waiting' folder
-r --recheck        visit 'waiting' folder
-a --archive        visit 'archive' folder
-n --newbies        visit 'newbies' folder
-u --publish        visit 'publish' folder
-s --skipsort       skip sorting of aggregate results by age
-l --lines rows     print top 'rows' of the result object [default: 50]
-z --ping           run the connectivity check first
-h --help           show this help text
-x --usage          show help and short example usage 

where ARG... can be one or more file name, or directories or package names.

Examples:
  ciw.r -ip                            # run in 'inspect' and 'pending' mode
  ciw.r -a                             # run with mode 'auto' resolved in incoming()
  ciw.r                                # run with defaults, same as '-itpwr'

When no argument is given, 'auto' is selected which corresponds to 'inspect', 'waiting',
'pending', 'pretest', and 'recheck'. Selecting '-m' or '--mega' are select as default.

Folder selecting arguments are cumulative; but 'mega' is a single selections of all folders
(i.e. 'inspect', 'waiting', 'pending', 'pretest', 'recheck', 'archive', 'newbies', 'publish').

ciw.r is part of littler which brings 'r' to the command-line.
See https://dirk.eddelbuettel.com/code/littler.html for more information.
edd@rob:~$ 
The README at the git repo and the CRAN page offer a screenshot movie showing some of the options in action. I have been using the little tools quite a bit over the last two or three weeks since I first put it together and find it quite handy. With that again a big Thank You! of appcreciation for all that CRAN does which this week included letting this past the newbies desk in under 24 hours. If you like this or other open-source work I do, you can sponsor me at GitHub.

Russell Coker: The Shape of Computers

Introduction There have been many experiments with the sizes of computers, some of which have stayed around and some have gone away. The trend has been to make computers smaller, the early computers had buildings for them. Recently for come classes computers have started becoming as small as could be reasonably desired. For example phones are thin enough that they can blow away in a strong breeze, smart watches are much the same size as the old fashioned watches they replace, and NUC type computers are as small as they need to be given the size of monitors etc that they connect to. This means that further development in the size and shape of computers will largely be determined by human factors. I think we need to consider how computers might be developed to better suit humans and how to write free software to make such computers usable without being constrained by corporate interests. Those of us who are involved in developing OSs and applications need to consider how to adjust to the changes and ideally anticipate changes. While we can t anticipate the details of future devices we can easily predict general trends such as being smaller, higher resolution, etc. Desktop/Laptop PCs When home computers first came out it was standard to have the keyboard in the main box, the Apple ][ being the most well known example. This has lost popularity due to the demand to have multiple options for a light keyboard that can be moved for convenience combined with multiple options for the box part. But it still pops up occasionally such as the Raspberry Pi 400 [1] which succeeds due to having the computer part being small and light. I think this type of computer will remain a niche product. It could be used in a add a screen to make a laptop as opposed to the add a keyboard to a tablet to make a laptop model but a tablet without a keyboard is more useful than a non-server PC without a display. The PC as box with connections for keyboard, display, etc has a long future ahead of it. But the sizes will probably decrease (they should have stopped making PC cases to fit CD/DVD drives at least 10 years ago). The NUC size is a useful option and I think that DVD drives will stop being used for software soon which will allow a range of smaller form factors. The regular laptop is something that will remain useful, but the tablet with detachable keyboard devices could take a lot of that market. Full functionality for all tasks requires a keyboard because at the moment text editing with a touch screen is an unsolved problem in computer science [2]. The Lenovo Thinkpad X1 Fold [3] and related Lenovo products are very interesting. Advances in materials allow laptops to be thinner and lighter which leaves the screen size as a major limitation to portability. There is a conflict between desiring a large screen to see lots of content and wanting a small size to carry and making a device foldable is an obvious solution that has recently become possible. Making a foldable laptop drives a desire for not having a permanently attached keyboard which then makes a touch screen keyboard a requirement. So this means that user interfaces for PCs have to be adapted to work well on touch screens. The Think line seems to be continuing the history of innovation that it had when owned by IBM. There are also a range of other laptops that have two regular screens so they are essentially the same as the Thinkpad X1 Fold but with two separate screens instead of one folding one, prices are as low as $600US. I think that the typical interfaces for desktop PCs (EG MS-Windows and KDE) don t work well for small devices and touch devices and the Android interface generally isn t a good match for desktop systems. We need to invent more options for this. This is not a criticism of KDE, I use it every day and it works well. But it s designed for use cases that don t match new hardware that is on sale. As an aside it would be nice if Lenovo gave samples of their newest gear to people who make significant contributions to GUIs. Give a few Thinkpad Fold devices to KDE people, a few to GNOME people, and a few others to people involved in Wayland development and see how that promotes software development and future sales. We also need to adopt features from laptops and phones into desktop PCs. When voice recognition software was first released in the 90s it was for desktop PCs, it didn t take off largely because it wasn t very accurate (none of them recognised my voice). Now voice recognition in phones is very accurate and it s very common for desktop PCs to have a webcam or headset with a microphone so it s time for this to be re-visited. GPS support in laptops is obviously useful and can work via Wifi location, via a USB GPS device, or via wwan mobile phone hardware (even if not used for wwan networking). Another possibility is using the same software interfaces as used for GPS on laptops for a static definition of location for a desktop PC or server. The Interesting New Things Watch Like The wrist-watch [4] has been a standard format for easy access to data when on the go since it s military use at the end of the 19th century when the practical benefits beat the supposed femininity of the watch. So it seems most likely that they will continue to be in widespread use in computerised form for the forseeable future. For comparison smart phones have been in widespread use as pocket watches for about 10 years. The question is how will watch computers end up? Will we have Dick Tracy style watch phones that you speak into? Will it be the current smart watch functionality of using the watch to answer a call which goes to a bluetooth headset? Will smart watches end up taking over the functionality of the calculator watch [5] which was popular in the 80 s? With today s technology you could easily have a fully capable PC strapped to your forearm, would that be useful? Phone Like Folding phones (originally popularised as Star Trek Tricorders) seem likely to have a long future ahead of them. Engineering technology has only recently developed to the stage of allowing them to work the way people would hope them to work (a folding screen with no gaps). Phones and tablets with multiple folds are coming out now [6]. This will allow phones to take much of the market share that tablets used to have while tablets and laptops merge at the high end. I ve previously written about Convergence between phones and desktop computers [7], the increased capabilities of phones adds to the case for Convergence. Folding phones also provide new possibilities for the OS. The Oppo OnePlus Open and the Google Pixel Fold both have a UI based around using the two halves of the folding screen for separate data at some times. I think that the current user interfaces for desktop PCs don t properly take advantage of multiple monitors and the possibilities raised by folding phones only adds to the lack. My pet peeve with multiple monitor setups is when they don t make it obvious which monitor has keyboard focus so you send a CTRL-W or ALT-F4 to the wrong screen by mistake, it s a problem that also happens on a single screen but is worse with multiple screens. There are rumours of phones described as three fold (where three means the number of segments with two folds between them), it will be interesting to see how that goes. Will phones go the same way as PCs in terms of having a separation between the compute bit and the input device? It s quite possible to have a compute device in the phone form factor inside a secure pocket which talks via Bluetooth to another device with a display and speakers. Then you could change your phone between a phone-size display and a tablet sized display easily and when using your phone a thief would not be able to easily steal the compute bit (which has passwords etc). Could the watch part of the phone (strapped to your wrist and difficult to steal) be the active part and have a tablet size device as an external display? There are already announcements of smart watches with up to 1GB of RAM (same as the Samsung Galaxy S3), that s enough for a lot of phone functionality. The Rabbit R1 [8] and the Humane AI Pin [9] have some interesting possibilities for AI speech interfaces. Could that take over some of the current phone use? It seems that visually impaired people have been doing badly in the trend towards touch screen phones so an option of a voice interface phone would be a good option for them. As an aside I hope some people are working on AI stuff for FOSS devices. Laptop Like One interesting PC variant I just discovered is the Higole 2 Pro portable battery operated Windows PC with 5.5 touch screen [10]. It looks too thick to fit in the same pockets as current phones but is still very portable. The version with built in battery is $AU423 which is in the usual price range for low end laptops and tablets. I don t think this is the future of computing, but it is something that is usable today while we wait for foldable devices to take over. The recent release of the Apple Vision Pro [11] has driven interest in 3D and head mounted computers. I think this could be a useful peripheral for a laptop or phone but it won t be part of a primary computing environment. In 2011 I wrote about the possibility of using augmented reality technology for providing a desktop computing environment [12]. I wonder how a Vision Pro would work for that on a train or passenger jet. Another interesting thing that s on offer is a laptop with 7 touch screen beside the keyboard [13]. It seems that someone just looked at what parts are available cheaply in China (due to being parts of more popular devices) and what could fit together. I think a keyboard should be central to the monitor for serious typing, but there may be useful corner cases where typing isn t that common and a touch-screen display is of use. Developing a range of strange hardware and then seeing which ones get adopted is a good thing and an advantage of Ali Express and Temu. Useful Hardware for Developing These Things I recently bought a second hand Thinkpad X1 Yoga Gen3 for $359 which has stylus support [14], and it s generally a great little laptop in every other way. There s a common failure case of that model where touch support for fingers breaks but the stylus still works which allows it to be used for testing touch screen functionality while making it cheap. The PineTime is a nice smart watch from Pine64 which is designed to be open [15]. I am quite happy with it but haven t done much with it yet (apart from wearing it every day and getting alerts etc from Android). At $50 when delivered to Australia it s significantly more expensive than most smart watches with similar features but still a lot cheaper than the high end ones. Also the Raspberry Pi Watch [16] is interesting too. The PinePhonePro is an OK phone made to open standards but it s hardware isn t as good as Android phones released in the same year [17]. I ve got some useful stuff done on mine, but the battery life is a major issue and the screen resolution is low. The Librem 5 phone from Purism has a better hardware design for security with switches to disable functionality [18], but it s even slower than the PinePhonePro. These are good devices for test and development but not ones that many people would be excited to use every day. Wwan hardware (for accessing the phone network) in M.2 form factor can be obtained for free if you have access to old/broken laptops. Such devices start at about $35 if you want to buy one. USB GPS devices also start at about $35 so probably not worth getting if you can get a wwan device that does GPS as well. What We Must Do Debian appears to have some voice input software in the pocketsphinx package but no documentation on how it s to be used. This would be a good thing to document, I spent 15 mins looking at it and couldn t get it going. To take advantage of the hardware features in phones we need software support and we ideally don t want free software to lag too far behind proprietary software which IMHO means the typical Android setup for phones/tablets. Support for changing screen resolution is already there as is support for touch screens. Support for adapting the GUI to changed screen size is something that needs to be done even today s hardware of connecting a small laptop to an external monitor doesn t have the ideal functionality for changing the UI. There also seem to be some limitations in touch screen support with multiple screens, I haven t investigated this properly yet, it definitely doesn t work in an expected manner in Ubuntu 22.04 and I haven t yet tested the combinations on Debian/Unstable. ML is becoming a big thing and it has some interesting use cases for small devices where a smart device can compensate for limited input options. There s a lot of work that needs to be done in this area and we are limited by the fact that we can t just rip off the work of other people for use as training data in the way that corporations do. Security is more important for devices that are at high risk of theft. The vast majority of free software installations are way behind Android in terms of security and we need to address that. I have some ideas for improvement but there is always a conflict between security and usability and while Android is usable for it s own special apps it s not usable in a I want to run applications that use any files from any other applicationsin any way I want sense. My post about Sandboxing Phone apps is relevant for people who are interested in this [19]. We also need to extend security models to cope with things like ok google type functionality which has the potential to be a bug and the emerging class of LLM based attacks. I will write more posts about these thing. Please write comments mentioning FOSS hardware and software projects that address these issues and also documentation for such things.

Russell Coker: Android vs FOSS Phones

To achieve my aims regarding Convergence of mobile phone and PC [1] I need something a big bigger than the 4G of RAM that s in the PinePhone Pro [2]. The PinePhonePro was released at the end of 2021 but has a SoC that was first released in 2016. That SoC seems to compare well to the ones used in the Pixel and Pixel 2 phones that were released in the same time period so it s not a bad SoC, but it doesn t compare well to more recent Android devices and it also isn t a great fit for the non-Android things I want to do. Also the PinePhonePro and Librem5 have relatively short battery life so reusing Android functionality for power saving could provide a real benefit. So I want a phone designed for the mass market that I can use for running Debian. PostmarketOS One thing I m definitely not going to do is attempt a full port of Linux to a different platform or support of kernel etc. So I need to choose a device that already has support from a somewhat free Linux system. The PostmarketOS system is the first I considered, the PostmarketOS Wiki page of supported devices [3] was the first place I looked. The main supported devices are the PinePhone (not Pro) and the Librem5, both of which are under-powered. For the community devices there seems to be nothing that supports calls, SMS, mobile data, and USB-OTG and which also has 4G of RAM or more. If I skip USB-OTG (which presumably means I d have to get dock functionality via wifi not impossible but not great) then I m left with the SHIFT6mq which was never sold in Australia and the Xiomi POCO F1 which doesn t appear to be available on ebay. LineageOS The libhybris libraries are a compatibility layer between Android and glibc programs [4]. Which includes running Wayland with Android display drivers. So running a somewhat standard Linux desktop on top of an Android kernel should be possible. Here is a table of the LineageOS supported devices that seem to have a useful feature set and are available in Australia and which could be used for running Debian with firmware and drivers copied from Android. I only checked LineageOS as it seems to be the main free Android build.
Phone RAM External Display Price
Edge 20 Pro [5] 6-12G HDMI $500 not many on sale
Edge S aka moto G100 [6] 6-8G HDMI $500 to $600+
Fairphone 4 6-8G USBC-DP $1000+
Nubia Red Magic 5G 8-16G USBC-DP $600+
The LineageOS device search page [9] allows searching by kernel version. There are no phones with a 6.6 (2023) or 6.1 (2022) Linux kernel and only the Pixel 8/8Pro and the OnePlus 11 5G run 5.15 (2021). There are 8 Google devices (Pixel 6/7 and a tablet) running 5.10 (2020), 18 devices running 5.4 (2019), and 32 devices running 4.19 (2018). There are 186 devices running kernels older than 4.19 which aren t in the kernel.org supported release list [10]. The Pixel 8 Pro with 12G of RAM and the OnePlus 11 5G with 16G of RAM are appealing as portable desktop computers, until recently my main laptop had 8G of RAM. But they cost over $1000 second hand compared to $359 for my latest laptop. Fosdem had an interesting lecture from two Fairphone employees about what they are doing to make phone production fairer for workers and less harmful for the environment [11]. But they don t have the market power that companies like Google have to tell SoC vendors what they want. IP Laws and Practices Bunnie wrote an insightful and informative blog post about the difference between intellectual property practices in China and US influenced countries and his efforts to reverse engineer a commonly used Chinese SoC [12]. This is a major factor in the lack of support for FOSS on phones and other devices. Droidian and Buying a Note 9 The FOSDEM 2023 has a lecture about the Droidian project which runs Debian with firmware and drivers from Android to make a usable mostly-FOSS system [13]. It s interesting how they use containers for the necessary Android apps. Here is the list of devices supported by Droidian [14]. Two notable entries in the list of supported devices are the Volla Phone and Volla Phone 22 from Volla a company dedicated to making open Android based devices [15]. But they don t seem to be available on ebay and the new price of the Volla Phone 22 is E452 ($AU750) which is more than I want to pay for a device that isn t as open as the Pine64 and Purism products. The Volla Phone 22 only has 4G of RAM.
Phone RAM Price Issues
Note 9 128G/512G 6G/8G <$300 Not supporting external display
Galaxy S9+ 6G <$300 Not supporting external display
Xperia 5 6G >$300 Hotspot partly working
OnePlus 3T 6G $200 $400+ photos not working
I just bought a Note 9 with 128G of storage and 6G of RAM for $109 to try out Droidian, it has some screen burn but that s OK for a test system and if I end up using it seriously I ll just buy another that s in as-new condition. With no support for an external display I ll need to setup a software dock to do Convergence, but that s not a serious problem. If I end up making a Note 9 with Droidian my daily driver then I ll use the 512G/8G model for that and use the cheap one for testing. Mobian I should have checked the Mobian list first as it s the main Debian variant for phones. From the Mobian Devices list [16] the OnePlus 6T has 8G of RAM or more but isn t available in Australia and costs more than $400 when imported. The PocoPhone F1 doesn t seem to be available on ebay. The Shift6mq is made by a German company with similar aims to the Fairphone [17], it looks nice but costs E577 which is more than I want to spend and isn t on the officially supported list. Smart Watches The same issues apply to smart watches. AstereoidOS is a free smart phone OS designed for closed hardware [18]. I don t have time to get involved in this sort of thing though, I can t hack on every device I use.

Valhalla's Things: Denim Waistcoat

Posted on March 8, 2024
Tags: madeof:atoms, craft:sewing, FreeSoftWear
A woman wearing a single breasted waistcoat with double darts at the waist, two pocket flaps at the waist and one on the left upper breast. It has four jeans buttons. I had finished sewing my jeans, I had a scant 50 cm of elastic denim left. Unrelated to that, I had just finished drafting a vest with Valentina, after the Cutters Practical Guide to the Cutting of Ladies Garments. A new pattern requires a (wearable) mockup. 50 cm of leftover fabric require a quick project. The decision didn t take a lot of time. As a mockup, I kept things easy: single layer with no lining, some edges finished with a topstitched hem and some with bias tape, and plain tape on the fronts, to give more support to the buttons and buttonholes. I did add pockets: not real welt ones (too much effort on denim), but simple slits covered by flaps. a rectangle of pocketing fabric on the wrong side of a denim
piece; there is a slit in the middle that has been finished with topstitching.
To do them I marked the slits, then I cut two rectangles of pocketing fabric that should have been as wide as the slit + 1.5 cm (width of the pocket) + 3 cm (allowances) and twice the sum of as tall as I wanted the pocket to be plus 1 cm (space above the slit) + 1.5 cm (allowances). Then I put the rectangle on the right side of the denim, aligned so that the top edge was 2.5 cm above the slit, sewed 2 mm from the slit, cut, turned the pocketing to the wrong side, pressed and topstitched 2 mm from the fold to finish the slit. a piece of pocketing fabric folded in half and sewn on all 3
other sides; it does not lay flat on the right side of the fabric because the finished slit (hidden in the picture) is pulling it.
Then I turned the pocketing back to the right side, folded it in half, sewed the side and top seams with a small allowance, pressed and turned it again to the wrong side, where I sewed the seams again to make a french seam. And finally, a simple rectangular denim flap was topstitched to the front, covering the slits. I wasn t as precise as I should have been and the pockets aren t exactly the right size, but they will do to see if I got the positions right (I think that the breast one should be a cm or so lower, the waist ones are fine), and of course they are tiny, but that s to be expected from a waistcoat. The back of the waistcoat, The other thing that wasn t exactly as expected is the back: the pattern splits the bottom part of the back to give it sufficient spring over the hips . The book is probably published in 1892, but I had already found when drafting the foundation skirt that its idea of hips includes a bit of structure. The enough steel to carry a book or a cup of tea kind of structure. I should have expected a lot of spring, and indeed that s what I got. To fit the bottom part of the back on the limited amount of fabric I had to piece it, and I suspect that the flat felled seam in the center is helping it sticking out; I don t think it s exactly bad, but it is a peculiar look. Also, I had to cut the back on the fold, rather than having a seam in the middle and the grain on a different angle. Anyway, my next waistcoat project is going to have a linen-cotton lining and silk fashion fabric, and I d say that the pattern is good enough that I can do a few small fixes and cut it directly in the lining, using it as a second mockup. As for the wrinkles, there is quite a bit, but it looks something that will be solved by a bit of lightweight boning in the side seams and in the front; it will be seen in the second mockup and the finished waistcoat. As for this one, it s definitely going to get some wear as is, in casual contexts. Except. Well, it s a denim waistcoat, right? With a very different cut from the get a denim jacket and rip out the sleeves , but still a denim waistcoat, right? The kind that you cover in patches, right? Outline of a sewing machine with teeth and crossed bones below it, and the text  home sewing is killing fashion / and it's illegal And I may have screenprinted a home sewing is killing fashion patch some time ago, using the SVG from wikimedia commons / the Home Taping is Killing Music page. And. Maybe I ll wait until I have finished the real waistcoat. But I suspect that one, and other sewing / costuming patches may happen in the future. No regrets, as the words on my seam ripper pin say, right? :D

Dirk Eddelbuettel: prrd 0.0.6 at CRAN: Several Improvements

Thrilled to share that a new version of prrd arrived at CRAN yesterday in a first update in two and a half years. prrd facilitates the parallel running [of] reverse dependency [checks] when preparing R packages. It is used extensively for releases I make of Rcpp, RcppArmadillo, RcppEigen, BH, and others. prrd screenshot image The key idea of prrd is simple, and described in some more detail on its webpage and its GitHub repo. Reverse dependency checks are an important part of package development that is easily done in a (serial) loop. But these checks are also generally embarassingly parallel as there is no or little interdependency between them (besides maybe shared build depedencies). See the (dated) screenshot (running six parallel workers, arranged in a split byobu session). This release, the first since 2021, brings a number of enhancments. In particular, the summary function is now improved in several ways. Josh also put in a nice PR that generalizes some setup defaults and values. The release is summarised in the NEWS entry:

Changes in prrd version 0.0.6 (2024-03-06)
  • The summary function has received several enhancements:
    • Extended summary is only running when failures are seen.
    • The summariseQueue function now displays an anticipated completion time and remaining duration.
    • The use of optional package foghorn has been refined, and refactored, when running summaries.
  • The dequeueJobs.r scripts can receive a date argument, the date can be parse via anydate if anytime ins present.
  • The enqueeJobs.r now considers skipped package when running 'addfailed' while ensuring selecting packages are still on CRAN.
  • The CI setup has been updated (twice),
  • Enqueing and dequing functions and scripts now support relative directories, updated documentation (#18 by Joshua Ulrich).

Courtesy of my CRANberries, there is also a diffstat report for this release. If you like this or other open-source work I do, you can sponsor me at GitHub.

Ravi Dwivedi: Fixing Mobile Data issue on Lineage OS

I have used Lineage OS on a couple of phones, but I noticed that internet using my mobile data was not working well on it. I am not sure why. This was the case in Xiaomi MI A2 and OnePlus 9 Pro phones. One day I met contrapunctus and they looked at their phone settings and used the same in mine and it worked. So, I am going to write here what worked for me. The trick is to add an access point. Go to Settings -> Network Settings -> Your SIM settings -> Access Point Names -> Click on + symbol. In the Name section, you can write anything, I wrote test. And in the APN section write www, then save. Below is a screenshot demonstrating the settings you have to change.
APN settings screenshot. Notice the circled entries.
This APN will show in the list of APNs and you need to select this one. After this, my mobile data started working well and I started getting speeds according to my data plan. This is what worked for me in Lineage OS. Hopefully, it was of help to you :D I will meet you in the next post.

Russ Allbery: Review: The Fund

Review: The Fund, by Rob Copeland
Publisher: St. Martin's Press
Copyright: 2023
ISBN: 1-250-27694-2
Format: Kindle
Pages: 310
I first became aware of Ray Dalio when either he or his publisher plastered advertisements for The Principles all over the San Francisco 4th and King Caltrain station. If I recall correctly, there were also constant radio commercials; it was a whole thing in 2017. My brain is very good at tuning out advertisements, so my only thought at the time was "some business guy wrote a self-help book." I think I vaguely assumed he was a CEO of some traditional business, since that's usually who writes heavily marketed books like this. I did not connect him with hedge funds or Bridgewater, which I have a bad habit of confusing with Blackwater. The Principles turns out to be more of a laundered cult manual than a self-help book. And therein lies a story. Rob Copeland is currently with The New York Times, but for many years he was the hedge fund reporter for The Wall Street Journal. He covered, among other things, Bridgewater Associates, the enormous hedge fund founded by Ray Dalio. The Fund is a biography of Ray Dalio and a history of Bridgewater from its founding as a vehicle for Dalio's advising business until 2022 when Dalio, after multiple false starts and title shuffles, finally retired from running the company. (Maybe. Based on the history recounted here, it wouldn't surprise me if he was back at the helm by the time you read this.) It is one of the wildest, creepiest, and most abusive business histories that I have ever read. It's probably worth mentioning, as Copeland does explicitly, that Ray Dalio and Bridgewater hate this book and claim it's a pack of lies. Copeland includes some of their denials (and many non-denials that sound as good as confirmations to me) in footnotes that I found increasingly amusing.
A lawyer for Dalio said he "treated all employees equally, giving people at all levels the same respect and extending them the same perks."
Uh-huh. Anyway, I personally know nothing about Bridgewater other than what I learned here and the occasional mention in Matt Levine's newsletter (which is where I got the recommendation for this book). I have no independent information whether anything Copeland describes here is true, but Copeland provides the typical extensive list of notes and sourcing one expects in a book like this, and Levine's comments indicated it's generally consistent with Bridgewater's industry reputation. I think this book is true, but since the clear implication is that the world's largest hedge fund was primarily a deranged cult whose employees mostly spied on and rated each other rather than doing any real investment work, I also have questions, not all of which Copeland answers to my satisfaction. But more on that later. The center of this book are the Principles. These were an ever-changing list of rules and maxims for how people should conduct themselves within Bridgewater. Per Copeland, although Dalio later published a book by that name, the version of the Principles that made it into the book was sanitized and significantly edited down from the version used inside the company. Dalio was constantly adding new ones and sometimes changing them, but the common theme was radical, confrontational "honesty": never being silent about problems, confronting people directly about anything that they did wrong, and telling people all of their faults so that they could "know themselves better." If this sounds like textbook abusive behavior, you have the right idea. This part Dalio admits to openly, describing Bridgewater as a firm that isn't for everyone but that achieves great results because of this culture. But the uncomfortably confrontational vibes are only the tip of the iceberg of dysfunction. Here are just a few of the ways this played out according to Copeland: In one of the common and all-too-disturbing connections between Wall Street finance and the United States' dysfunctional government, James Comey (yes, that James Comey) ran internal security for Bridgewater for three years, meaning that he was the one who pulled evidence from surveillance cameras for Dalio to use to confront employees during his trials. In case the cult vibes weren't strong enough already, Bridgewater developed its own idiosyncratic language worthy of Scientology. The trials were called "probings," firing someone was called "sorting" them, and rating them was called "dotting," among many other Bridgewater-specific terms. Needless to say, no one ever probed Dalio himself. You will also be completely unsurprised to learn that Copeland documents instances of sexual harassment and discrimination at Bridgewater, including some by Dalio himself, although that seems to be a relatively small part of the overall dysfunction. Dalio was happy to publicly humiliate anyone regardless of gender. If you're like me, at this point you're probably wondering how Bridgewater continued operating for so long in this environment. (Per Copeland, since Dalio's retirement in 2022, Bridgewater has drastically reduced the cult-like behaviors, deleted its archive of probings, and de-emphasized the Principles.) It was not actually a religious cult; it was a hedge fund that has to provide investment services to huge, sophisticated clients, and by all accounts it's a very successful one. Why did this bizarre nightmare of a workplace not interfere with Bridgewater's business? This, I think, is the weakest part of this book. Copeland makes a few gestures at answering this question, but none of them are very satisfying. First, it's clear from Copeland's account that almost none of the employees of Bridgewater had any control over Bridgewater's investments. Nearly everyone was working on other parts of the business (sales, investor relations) or on cult-related obsessions. Investment decisions (largely incorporated into algorithms) were made by a tiny core of people and often by Dalio himself. Bridgewater also appears to not trade frequently, unlike some other hedge funds, meaning that they probably stay clear of the more labor-intensive high-frequency parts of the business. Second, Bridgewater took off as a hedge fund just before the hedge fund boom in the 1990s. It transformed from Dalio's personal consulting business and investment newsletter to a hedge fund in 1990 (with an earlier investment from the World Bank in 1987), and the 1990s were a very good decade for hedge funds. Bridgewater, in part due to Dalio's connections and effective marketing via his newsletter, became one of the largest hedge funds in the world, which gave it a sort of institutional momentum. No one was questioned for putting money into Bridgewater even in years when it did poorly compared to its rivals. Third, Dalio used the tried and true method of getting free publicity from the financial press: constantly predict an upcoming downturn, and aggressively take credit whenever you were right. From nearly the start of his career, Dalio predicted economic downturns year after year. Bridgewater did very well in the 2000 to 2003 downturn, and again during the 2008 financial crisis. Dalio aggressively takes credit for predicting both of those downturns and positioning Bridgewater correctly going into them. This is correct; what he avoids mentioning is that he also predicted downturns in every other year, the majority of which never happened. These points together create a bit of an answer, but they don't feel like the whole picture and Copeland doesn't connect the pieces. It seems possible that Dalio may simply be good at investing; he reads obsessively and clearly enjoys thinking about markets, and being an abusive cult leader doesn't take up all of his time. It's also true that to some extent hedge funds are semi-free money machines, in that once you have a sufficient quantity of money and political connections you gain access to investment opportunities and mechanisms that are very likely to make money and that the typical investor simply cannot access. Dalio is clearly good at making personal connections, and invested a lot of effort into forming close ties with tricky clients such as pools of Chinese money. Perhaps the most compelling explanation isn't mentioned directly in this book but instead comes from Matt Levine. Bridgewater touts its algorithmic trading over humans making individual trades, and there is some reason to believe that consistently applying an algorithm without regard to human emotion is a solid trading strategy in at least some investment areas. Levine has asked in his newsletter, tongue firmly in cheek, whether the bizarre cult-like behavior and constant infighting is a strategy to distract all the humans and keep them from messing with the algorithm and thus making bad decisions. Copeland leaves this question unsettled. Instead, one comes away from this book with a clear vision of the most dysfunctional workplace I have ever heard of, and an endless litany of bizarre events each more astonishing than the last. If you like watching train wrecks, this is the book for you. The only drawback is that, unlike other entries in this genre such as Bad Blood or Billion Dollar Loser, Bridgewater is a wildly successful company, so you don't get the schadenfreude of seeing a house of cards collapse. You do, however, get a helpful mental model to apply to the next person who tries to talk to you about "radical honesty" and "idea meritocracy." The flaw in this book is that the existence of an organization like Bridgewater is pointing to systematic flaws in how our society works, which Copeland is largely uninterested in interrogating. "How could this have happened?" is a rather large question to leave unanswered. The sheer outrageousness of Dalio's behavior also gets a bit tiring by the end of the book, when you've seen the patterns and are hearing about the fourth variation. But this is still an astonishing book, and a worthy entry in the genre of capitalism disasters. Rating: 7 out of 10

Niels Thykier: Expanding on the Language Server (LSP) support for debian/control

I have spent some more time on improving my language server for debian/control. Today, I managed to provide the following features:
  • The X- style prefixes for field names are now understood and handled. This means the language server now considers XC-Package-Type the same as Package-Type.

  • More diagnostics:

    • Fields without values now trigger an error marker
    • Duplicated fields now trigger an error marker
    • Fields used in the wrong paragraph now trigger an error marker
    • Typos in field names or values now trigger a warning marker. For field names, X- style prefixes are stripped before typo detection is done.
    • The value of the Section field is now validated against a dataset of known sections and trigger a warning marker if not known.
  • The "on-save trim end of line whitespace" now works. I had a logic bug in the server side code that made it submit "no change" edits to the editor.

  • The language server now provides "hover" documentation for field names. There is a small screenshot of this below. Sadly, emacs does not support markdown or, if it does, it does not announce the support for markdown. For now, all the documentation is always in markdown format and the language server will tag it as either markdown or plaintext depending on the announced support.

  • The language server now provides quick fixes for some of the more trivial problems such as deprecated fields or typos of fields and values.

  • Added more known fields including the XS-Autobuild field for non-free packages along with a link to the relevant devref section in its hover doc.

This covers basically all my known omissions from last update except spellchecking of the Description field. An image of emacs showing documentation for the Provides field from the language server.
Spellchecking Personally, I feel spellchecking would be a very welcome addition to the current feature set. However, reviewing my options, it seems that most of the spellchecking python libraries out there are not packaged for Debian, or at least not other the name I assumed they would be. The alternative is to pipe the spellchecking to another program like aspell list. I did not test this fully, but aspell list does seem to do some input buffering that I cannot easily default (at least not in the shell). Though, either way, the logic for this will not be trivial and aspell list does not seem to include the corrections either. So best case, you would get typo markers but no suggestions for what you should have typed. Not ideal. Additionally, I am also concerned with the performance for this feature. For d/control, it will be a trivial matter in practice. However, I would be reusing this for d/changelog which is 99% free text with plenty of room for typos. For a regular linter, some slowness is acceptable as it is basically a batch tool. However, for a language server, this potentially translates into latency for your edits and that gets annoying. While it is definitely on my long term todo list, I am a bit afraid that it can easily become a time sink. Admittedly, this does annoy me, because I wanted to cross off at least one of Otto's requested features soon.
On wrap-and-sort support The other obvious request from Otto would be to automate wrap-and-sort formatting. Here, the problem is that "we" in Debian do not agree on the one true formatting of debian/control. In fact, I am fairly certain we do not even agree on whether we should all use wrap-and-sort. This implies we need a style configuration. However, if we have a style configuration per person, then you get style "ping-pong" for packages where the co-maintainers do not all have the same style configuration. Additionally, it is very likely that you are a member of multiple packaging teams or groups that all have their own unique style. Ergo, only having a personal config file is doomed to fail. The only "sane" option here that I can think of is to have or support "per package" style configuration. Something that would be committed to git, so the tooling would automatically pick up the configuration. Obviously, that is not fun for large packaging teams where you have to maintain one file per package if you want a consistent style across all packages. But it beats "style ping-pong" any day of the week. Note that I am perfectly open to having a personal configuration file as a fallback for when the "per package" configuration file is absent. The second problem is the question of which format to use and what to name this file. Since file formats and naming has never been controversial at all, this will obviously be the easy part of this problem. But the file should be parsable by both wrap-and-sort and the language server, so you get the same result regardless of which tool you use. If we do not ensure this, then we still have the style ping-pong problem as people use different tools. This also seems like time sink with no end. So, what next then...?
What next? On the language server front, I will have a look at its support for providing semantic hints to the editors that might be used for syntax highlighting. While I think most common Debian editors have built syntax highlighting already, I would like this language server to stand on its own. I would like us to be in a situation where we do not have implement yet another editor extension for Debian packaging files. At least not for editors that support the LSP spec. On a different front, I have an idea for how we go about relationship related substvars. It is not directly related to this language server, except I got triggered by the language server "missing" a diagnostic for reminding people to add the magic Depends: $ misc:Depends [, $ shlibs:Depends ] boilerplate. The magic boilerplate that you have to write even though we really should just fix this at a tooling level instead. Energy permitting, I will formulate a proposal for that and send it to debian-devel. Beyond that, I think I might start adding support for another file. I also need to wrap up my python-debian branch, so I can get the position support into the Debian soon, which would remove one papercut for using this language server. Finally, it might be interesting to see if I can extract a "batch-linter" version of the diagnostics and related quickfix features. If nothing else, the "linter" variant would enable many of you to get a "mini-Lintian" without having to do a package build first.

Matthew Palmer: Not all TLDs are Created Equal

In light of the recent cancellation of the queer.af domain registration by the Taliban, the fragile and difficult nature of country-code top-level domains (ccTLDs) has once again been comprehensively demonstrated. Since many people may not be aware of the risks, I thought I d give a solid explainer of the whole situation, and explain why you should, in general, not have anything to do with domains which are registered under ccTLDs.

Top-level What-Now? A top-level domain (TLD) is the last part of a domain name (the collection of words, separated by periods, after the https:// in your web browser s location bar). It s the com in example.com, or the af in queer.af. There are two kinds of TLDs: country-code TLDs (ccTLDs) and generic TLDs (gTLDs). Despite all being TLDs, they re very different beasts under the hood.

What s the Difference? Generic TLDs are what most organisations and individuals register their domains under: old-school technobabble like com , net , or org , historical oddities like gov , and the new-fangled world of words like tech , social , and bank . These gTLDs are all regulated under a set of rules created and administered by ICANN (the Internet Corporation for Assigned Names and Numbers ), which try to ensure that things aren t a complete wild-west, limiting things like price hikes (well, sometimes, anyway), and providing means for disputes over names1. Country-code TLDs, in contrast, are all two letters long2, and are given out to countries to do with as they please. While ICANN kinda-sorta has something to do with ccTLDs (in the sense that it makes them exist on the Internet), it has no authority to control how a ccTLD is managed. If a country decides to raise prices by 100x, or cancel all registrations that were made on the 12th of the month, there s nothing anyone can do about it. If that sounds bad, that s because it is. Also, it s not a theoretical problem the Taliban deciding to asssert its bigotry over the little corner of the Internet namespace it has taken control of is far from the first time that ccTLDs have caused grief.

Shifting Sands The queer.af cancellation is interesting because, at the time the domain was reportedly registered, 2018, Afghanistan had what one might describe as, at least, a different political climate. Since then, of course, things have changed, and the new bosses have decided to get a bit more active. Those running queer.af seem to have seen the writing on the wall, and were planning on moving to another, less fraught, domain, but hadn t completed that move when the Taliban came knocking.

The Curious Case of Brexit When the United Kingdom decided to leave the European Union, it fell foul of the EU s rules for the registration of domains under the eu ccTLD3. To register (and maintain) a domain name ending in .eu, you have to be a resident of the EU. When the UK ceased to be part of the EU, residents of the UK were no longer EU residents. Cue much unhappiness, wailing, and gnashing of teeth when this was pointed out to Britons. Some decided to give up their domains, and move to other parts of the Internet, while others managed to hold onto them by various legal sleight-of-hand (like having an EU company maintain the registration on their behalf). In any event, all very unpleasant for everyone involved.

Geopolitics on the Internet?!? After Russia invaded Ukraine in February 2022, the Ukranian Vice Prime Minister asked ICANN to suspend ccTLDs associated with Russia. While ICANN said that it wasn t going to do that, because it wouldn t do anything useful, some domain registrars (the companies you pay to register domain names) ceased to deal in Russian ccTLDs, and some websites restricted links to domains with Russian ccTLDs. Whether or not you agree with the sort of activism implied by these actions, the fact remains that even the actions of a government that aren t directly related to the Internet can have grave consequences for your domain name if it s registered under a ccTLD. I don t think any gTLD operator will be invading a neighbouring country any time soon.

Money, Money, Money, Must Be Funny When you register a domain name, you pay a registration fee to a registrar, who does administrative gubbins and causes you to be able to control the domain name in the DNS. However, you don t own that domain name4 you re only renting it. When the registration period comes to an end, you have to renew the domain name, or you ll cease to be able to control it. Given that a domain name is typically your brand or identity online, the chances are you d prefer to keep it over time, because moving to a new domain name is a massive pain, having to tell all your customers or users that now you re somewhere else, plus having to accept the risk of someone registering the domain name you used to have and capturing your traffic it s all a gigantic hassle. For gTLDs, ICANN has various rules around price increases and bait-and-switch pricing that tries to keep a lid on the worst excesses of registries. While there are any number of reasonable criticisms of the rules, and the Internet community has to stay on their toes to keep ICANN from totally succumbing to regulatory capture, at least in the gTLD space there s some degree of control over price gouging. On the other hand, ccTLDs have no effective controls over their pricing. For example, in 2008 the Seychelles increased the price of .sc domain names from US$25 to US$75. No reason, no warning, just pay up .

Who Is Even Getting That Money? A closely related concern about ccTLDs is that some of the cool ones are assigned to countries that are not great. The poster child for this is almost certainly Libya, which has the ccTLD ly . While Libya was being run by a terrorist-supporting extremist, companies thought it was a great idea to have domain names that ended in .ly. These domain registrations weren t (and aren t) cheap, and it s hard to imagine that at least some of that money wasn t going to benefit the Gaddafi regime. Similarly, the British Indian Ocean Territory, which has the io ccTLD, was created in a colonialist piece of chicanery that expelled thousands of native Chagossians from Diego Garcia. Money from the registration of .io domains doesn t go to the (former) residents of the Chagos islands, instead it gets paid to the UK government. Again, I m not trying to suggest that all gTLD operators are wonderful people, but it s not particularly likely that the direct beneficiaries of the operation of a gTLD stole an island chain and evicted the residents.

Are ccTLDs Ever Useful? The answer to that question is an unqualified maybe . I certainly don t think it s a good idea to register a domain under a ccTLD for vanity purposes: because it makes a word, is the same as a file extension you like, or because it looks cool. Those ccTLDs that clearly represent and are associated with a particular country are more likely to be OK, because there is less impetus for the registry to try a naked cash grab. Unfortunately, ccTLD registries have a disconcerting habit of changing their minds on whether they serve their geographic locality, such as when auDA decided to declare an open season in the .au namespace some years ago. Essentially, while a ccTLD may have geographic connotations now, there s not a lot of guarantee that they won t fall victim to scope creep in the future. Finally, it might be somewhat safer to register under a ccTLD if you live in the location involved. At least then you might have a better idea of whether your domain is likely to get pulled out from underneath you. Unfortunately, as the .eu example shows, living somewhere today is no guarantee you ll still be living there tomorrow, even if you don t move house. In short, I d suggest sticking to gTLDs. They re at least lower risk than ccTLDs.

+1, Helpful If you ve found this post informative, why not buy me a refreshing beverage? My typing fingers (both of them) thank you in advance for your generosity.

Abhijith PA: A new(kind of) phone

I was using a refurbished Xiaomi Redmi 6 Pro (codename: sakura . I do remember buying this phone to run LineageOS as I found this model had support. But by the time I bought it (there was a quite a gap between my research and the actual purchase) lineageOS ended the suport for this device. The maintainer might ve ended this port, I don t blame them. Its a non rewarding work. Later I found there is a DotOS custom rom available. I did a week of test run. There seems lot of bugs and it all was minor and I can live with that. Since there is no other official port for redmi 6 pro at the time, I settled on this buggy DotOS nightly build. The phone was doing fine all these(3+) years, but recently the camera started showing greyish dots on some areas to a point that I can t even properly take a photo. The outer body of the phone wasn t original, as it was a refurbished, thus the colors started to peel off and wasn t aesthetically pleasing. Then there is the Location detection issue which took a while to figure out location and battery drains fast. I recently started mapping public transportation routes, and the GPS issue was a problem for me. With all these problems combined, I decided to buy a new phone. But choosing a phone wasn t easy. There are far too many options in the market. However, one thing I was quite sure of was that I wouldn t be buying a brand new phone, but a refurbished one. It is my protest against all these phone manufacturers who have convinced the general public that a mobile phone s lifespan is only 2 years. Of course, there are a few exceptions, but the majority of players in the Indian market are not. Now I think about it, I haven t bought any brand new computing device, be it phones or laptops since 2015. All are refurbished devices except for an Orange pi. My Samsung R439 laptop which I already blogged about is still going strong. Back to picking phone. So I began by comparing LineageOS website to an online refurbished store to pick a phone that has an official lineage support then to reddit search for any reported hardware failures Google Pixel phones are well-known in the custom ROM community for ease of installation, good hardware and Android security releases. My above claims are from privacyguides.org and XDA-developers. I was convinced to go with this choice. But I have some one at home who is at the age of throwing things. So I didn t want to risk buying an expensive Pixel phone only to have it end up with a broken screen and edges. Perhaps I will consider buying a Pixel next time. After doing some more research and cross comparison I landed up on Redmi note 9. Codename: merlinx. Based on my previous experience I knew it is going to be a pain to unlock the bootloader of Xiaomi phones and I was prepared for that but this time there was an extra hoop. The phone came with ROM MIUI version 13. A small search on XDA forums and reddit told unless we downgrade to 12 or so it is difficult to unlock bootloader for this device. And performing this wasn t exactly easy as we need tools like SP Flash etc. It took some time, but I ve completed the downgrade process. From there, the rest was cakewalk as everything was perfectly documented in LineageOS wiki. And ta-da, I have a phone running lineageOS. I been using it for some time and honestly I haven t come across any bug in my way of usage. One advice I will give to you if you are going to flash a custom ROM. There are plenty of videos about unlocking bootloader, installing ROMs in Youtube. Please REFRAIN from watching and experimenting it on your phone unless you figured a way to un brick your device first.

Next.
