command you already know). Now you could easily log in to a machine and exchange files with it without missing a beat.
And so it was that the Internet Kermit Service Daemon (IKSD) came into existence. It allows a person to set up a Kermit server, which can authenticate against local accounts or present anonymous access akin to FTP.
And so I established the quux.org Kermit Server, which runs the Unix IKSD (part of the Debian ckermit package).

buttonA personal reflection on how I moved from my Debian home to find two new homes with Trisquel and Guix for my own ethical computing, and while doing so settled my dilemma about further Debian contributions.
Debian s contributions to the free software community has been tremendous. Debian was one of the early distributions in the 1990 s that combined the GNU tools (compiler, linker, shell, editor, and a set of Unix tools) with the Linux kernel and published a free software operating system. Back then there were little guidance on how to publish free software binaries, let alone entire operating systems. There was a lack of established community processes and conflict resolution mechanisms, and lack of guiding principles to motivate the work. The community building efforts that came about in parallel with the technical work has resulted in a steady flow of releases over the years.
From the work of Richard Stallman and the Free Software Foundation (FSF) during the 1980 s and early 1990 s, there was at the time already an established definition of free software. Inspired by free software definition, and a belief that a social contract helps to build a community and resolve conflicts, Debian s social contract (DSC) with the free software community was published in 1997. The DSC included the Debian Free Software Guidelines (DFSG), which directly led to the Open Source Definition.
I was introduced to GNU/Linux through Slackware in the early 1990 s (oh boy those nights calculating XFree86 modeline s and debugging sendmail.cf) and primarily used RedHat Linux during ca 1995-2003. I switched to Debian during the Woody release cycles, when the original RedHat Linux was abandoned and Fedora launched. It was Debian s explicit community processes and infrastructure that attracted me. The slow nature of community processes also kept me using RedHat for so long: centralized and dogmatic decision processes often produce quick and effective outcomes, and in my opinion RedHat Linux was technically better than Debian ca 1995-2003. However the RedHat model was not sustainable, and resulted in the RedHat vs Fedora split. Debian catched up, and reached technical stability once its community processes had been grounded. I started participating in the Debian community around late 2006.
My interpretation of Debian s social contract is that Debian should be a distribution of works licensed 100% under a free license. The Debian community has always been inclusive towards non-free software, creating the contrib/non-free
section and permitting use of the bug tracker to help resolve issues with non-free works. This is all explained in the social contract. There has always been a clear boundary between free and non-free work, and there has been a commitment that the Debian system itself would be 100% free.
The concern that RedHat Linux was not 100% free software was not critical to me at the time: I primarily (and happily) ran GNU tools on Solaris, IRIX, AIX, OS/2, Windows etc. Running GNU tools on RedHat Linux was an improvement, and I hadn t realized it was possible to get rid of all non-free software on my own primary machine. Debian realized that goal for me. I ve been a believer in that model ever since. I can use Solaris, macOS, Android etc knowing that I have the option of using a 100% free Debian.
While the inclusive approach towards non-free software invite and deserve criticism (some argue that being inclusive to non-inclusive behavior is a bad idea), I believe that Debian s approach was a successful survival technique: by being inclusive to and a compromise between free and non-free communities, Debian has been able to stay relevant and contribute to both environments. If Debian had not served and contributed to the free community, I believe free software people would have stopped contributing. If Debian had rejected non-free works completely, I don t think the successful Ubuntu distribution would have been based on Debian.
I wrote the majority of the text above back in September 2022, intending to post it as a way to argue for my proposal to maintain the status quo within Debian. I didn t post it because I felt I was saying the obvious, and that the obvious do not need to be repeated, and the rest of the post was just me going down memory lane.
The Debian project has been a sustainable producer of a 100% free OS up until Debian 11 bullseye. In the resolution on non-free firmware the community decided to leave the model that had resulted in a 100% free Debian for so long. The goal of Debian is no longer to publish a 100% free operating system, instead this was added: The Debian official media may include firmware . Indeed the Debian 12 bookworm release has confirmed that this would not only be an optional possibility. The Debian community could have published a 100% free Debian, in parallel with the non-free Debian, and still be consistent with their newly adopted policy, but chose not to. The result is that Debian s policies are not consistent with their actions. It doesn t make sense to claim that Debian is 100% free when the Debian installer contains non-free software. Actions speaks louder than words, so I m left reading the policies as well-intended prose that is no longer used for guidance, but for the peace of mind for people living in ivory towers. And to attract funding, I suppose.
So how to deal with this, on a personal level? I did not have an answer to that back in October 2022 after the vote. It wasn t clear to me that I would ever want to contribute to Debian under the new social contract that promoted non-free software. I went on vacation from any Debian work. Meanwhile Debian 12 bookworm was released, confirming my fears. I kept coming back to this text, and my only take-away was that it would be unethical for me to use Debian on my machines. Letting actions speak for themselves, I switched to PureOS on my main laptop during October, barely noticing any difference since it is based on Debian 11 bullseye. Back in December, I bought a new laptop and tried Trisquel and Guix on it, as they promise a migration path towards ppc64el that PureOS do not.
While I pondered how to approach my modest Debian contributions, I set out to learn Trisquel and gained trust in it. I migrated one Debian machine after another to Trisquel, and started to use Guix on others. Migration was easy because Trisquel is based on Ubuntu which is based on Debian. Using Guix has its challenges, but I enjoy its coherant documented environment. All of my essential self-hosted servers (VM hosts, DNS, e-mail, WWW, Nextcloud, CI/CD builders, backup etc) uses Trisquel or Guix now. I ve migrated many GitLab CI/CD rules to use Trisquel instead of Debian, to have a more ethical computing base for software development and deployment. I wish there were official Guix docker images around.
Time has passed, and when I now think about any Debian contributions, I m a little less muddled by my disappointment of the exclusion of a 100% free Debian. I realize that today I can use Debian in the same way that I use macOS, Android, RHEL or Ubuntu. And what prevents me from contributing to free software on those platforms? So I will make the occasional Debian contribution again, knowing that it will also indirectly improve Trisquel. To avoid having to install Debian, I need a development environment in Trisquel that allows me to build Debian packages. I have found a recipe for doing this:
# System commands:
How to sustainably deliver a 100% free software binary distributions seems like an open question, and the challenges are not all that different compared to the 1990 s or early 2000 s. I m hoping Debian will come back to provide a 100% free platform, but my fear is that Debian will compromise even further on the free software ideals rather than the opposite. With similar arguments that were used to add the non-free firmware, Debian could compromise the free software spirit of the Linux boot process (e.g., non-free boot images signed by Debian) and media handling (e.g., web browsers and DRM), as Debian have already done with appstore-like functionality for non-free software (Python pip). To learn about other freedom issues in Debian packaging, browsing Trisquel s helper scripts may enlight you.
Debian s setback and the recent setback for RHEL-derived distributions are sad, and it will be a challenge for these communities to find internally consistent coherency going forward. I wish them the best of luck, as Debian and RHEL are important for the wider free software eco-system. Let s see how the community around Trisquel, Guix and the other FSDG-distributions evolve in the future.
The situation for free software today appears better than it was years ago regardless of Debian and RHEL s setbacks though, which is important to remember! I don t recall being able install a 100% free OS on a modern laptop and modern server as easily as I am able to do today.
Happy Hacking!
Addendum 22 July 2023: The original title of this post was Coping with non-free Debian, and there was a thread about it that included feedback on the title. I do agree that my initial title was confrontational, and I ve changed it to the more specific Coping with non-free software in Debian. I do appreciate all the fine free software that goes into Debian, and hope that this will continue and improve, although I have doubts given the opinions expressed by the majority of developers. For the philosophically inclined, it is interesting to think about what it means to say that a compilation of software is freely licensed. At what point does a compilation of software deserve the labels free vs non-free? Windows probably contains some software that is published as free software, let s say Windows is 1% free. Apple authors a lot of free software (as a tangent, Apple probably produce more free software than what Debian as an organization produces), and let s say macOS contains 20% free software. Solaris (or some still maintained derivative like OpenIndiana) is mostly freely licensed these days, isn t it? Let s say it is 80% free. Ubuntu and RHEL pushes that closer to let s say 95% free software. Debian used to be 100% but is now slightly less at maybe 99%. Trisquel and Guix are at 100%. At what point is it reasonable to call a compilation free? Does Debian deserve to be called freely licensed? Does macOS? Is it even possible to use these labels for compilations in any meaningful way? All numbers just taken from thin air. It isn t even clear how this can be measured (binary bytes? lines of code? CPU cycles? etc). The caveat about license review mistakes applies. I ignore Debian s own claims that Debian is 100% free software, which I believe is inconsistent and no longer true under any reasonable objective analysis. It was not true before the firmware vote since Debian ships with non-free blobs in the Linux kernel for example.

I find it hard to believe that anyone would take their actual production key and redact it for documentation. Does the author have evidence of this in practice, or did they see example keys and assume they were redacted production keys?Well, buckle up, because today s post is another real-world case study, with rather higher stakes than the previous example.

Searching for certificates which use that key fingerprint, we find one result: a certificate for hiltonhotels.jp
(and a bunch of other, related, domains, as subjectAltNames).
As of the time of writing, that certificate is not marked as revoked, and appears to be the same certificate that is currently presented to visitors of that site.
This is, shall we say, not great.
Anyone in possession of this private key which, I should emphasise, has presumably been public information since the post s publication date of February 2023 has the ability to completely transparently impersonate the sites listed in that certificate.
That would provide an attacker with the ability to capture any data a user entered, such as personal information, passwords, or payment details, and also modify what the user s browser received, including injecting malware or other unpleasantness.
In short, no good deed goes unpunished, and this attempt to educate the world at large about the benefits of secure key storage has instead published private key material.
Remember, kids: friends don t let friends post redacted private keys to the Internet.

Keep the peace. That was the thing. People often failed to understand what that meant. You'd go to some life-threatening disturbance like a couple of neighbors scrapping in the street over who owned the hedge between their properties, and they'd both be bursting with aggrieved self-righteousness, both yelling, their wives would either be having a private scrap on the side or would have adjourned to a kitchen for a shared pot of tea and a chat, and they all expected you to sort it out. And they could never understand that it wasn't your job. Sorting it out was a job for a good surveyor and a couple of lawyers, maybe. Your job was to quell the impulse to bang their stupid fat heads together, to ignore the affronted speeches of dodgy self-justification, to get them to stop shouting and to get them off the street. Once that had been achieved, your job was over. You weren't some walking god, dispensing finely tuned natural justice. Your job was simply to bring back peace.When Vimes is thrown back in time, he has to pick up the role of his own mentor, the person who taught him what policing should be like. His younger self is right there, watching everything he does, and he's desperately afraid he'll screw it up and set a worse example. Make history worse when he's trying to make it better. It's a beautifully well-done bit of tension that uses time travel as the hook to show both how difficult mentorship is and also how irritating one's earlier naive self would be.
He wondered if it was at all possible to give this idiot some lessons in basic politics. That was always the dream, wasn't it? "I wish I'd known then what I know now"? But when you got older you found out that you now wasn't you then. You then was a twerp. You then was what you had to be to start out on the rocky road of becoming you now, and one of the rocky patches on that road was being a twerp.The backdrop of this story, as advertised by the map at the front of the book, is a revolution of sorts. And the revolution does matter, but not in the obvious way. It creates space and circumstance for some other things to happen that are all about the abuse of policing as a tool of politics rather than Vimes's principle of keeping the peace. I mentioned when reviewing Men at Arms that it was an awkward book to read in the United States in 2020. This book tackles the ethics of policing head-on, in exactly the way that book didn't. It's also a marvelous bit of competence porn. Somehow over the years, Vimes has become extremely good at what he does, and not just in the obvious cop-walking-a-beat sort of ways. He's become a leader. It's not something he thinks about, even when thrown back in time, but it's something Pratchett can show the reader directly, and have the other characters in the book comment on. There is so much more that I'd like to say, but so much would be spoilers, and I think Night Watch is more effective when you have the suspense of slowly puzzling out what's going to happen. Pratchett's pacing is exquisite. It's also one of the rare Discworld novels where Pratchett fully commits to a point of view and lets Vimes tell the story. There are a few interludes with other people, but the only other significant protagonist is, quite fittingly, Vetinari. I won't say anything more about that except to note that the relationship between Vimes and Vetinari is one of the best bits of fascinating subtlety in all of Discworld. I think it's also telling that nothing about Night Watch reads as parody. Sure, there is a nod to Back to the Future in the lightning storm, and it's impossible to write a book about police and street revolutions without making the reader think about Les Miserables, but nothing about this plot matches either of those stories. This is Pratchett telling his own story in his own world, unapologetically, and without trying to wedge it into parody shape, and it is so much the better book for it. The one quibble I have with the book is that the bits with the Time Monks don't really work. Lu-Tze is annoying and flippant given the emotional stakes of this story, the interludes with him are frustrating and out of step with the rest of the book, and the time travel hand-waving doesn't add much. I see structurally why Pratchett put this in: it gives Vimes (and the reader) a time frame and a deadline, it establishes some of the ground rules and stakes, and it provides a couple of important opportunities for exposition so that the reader doesn't get lost. But it's not good story. The rest of the book is so amazingly good, though, that it doesn't matter (and the framing stories for "what if?" explorations almost never make much sense). The other thing I have a bit of a quibble with is outside the book. Night Watch, as you may have guessed by now, is the origin of the May 25th Pratchett memes that you will be familiar with if you've spent much time around SFF fandom. But this book is dramatically different from what I was expecting based on the memes. You will, for example see a lot of people posting "Truth, Justice, Freedom, Reasonably Priced Love, And a Hard-Boiled Egg!", and before reading the book it sounds like a Pratchett-style humorous revolutionary slogan. And I guess it is, sort of, but, well... I have to quote the scene:
"You'd like Freedom, Truth, and Justice, wouldn't you, Comrade Sergeant?" said Reg encouragingly. "I'd like a hard-boiled egg," said Vimes, shaking the match out. There was some nervous laughter, but Reg looked offended. "In the circumstances, Sergeant, I think we should set our sights a little higher " "Well, yes, we could," said Vimes, coming down the steps. He glanced at the sheets of papers in front of Reg. The man cared. He really did. And he was serious. He really was. "But...well, Reg, tomorrow the sun will come up again, and I'm pretty sure that whatever happens we won't have found Freedom, and there won't be a whole lot of Justice, and I'm damn sure we won't have found Truth. But it's just possible that I might get a hard-boiled egg."I think I'm feeling defensive of the heart of this book because it's such an emotional gut punch and says such complicated and nuanced things about politics and ethics (and such deeply cynical things about revolution). But I think if I were to try to represent this story in a meme, it would be the "angels rise up" song, with all the layers of meaning that it gains in this story. I'm still at the point where the lilac sprigs remind me of Sergeant Colon becoming quietly furious at the overstep of someone who wasn't there. There's one other thing I want to say about that scene: I'm not naturally on Vimes's side of this argument. I think it's important to note that Vimes's attitude throughout this book is profoundly, deeply conservative. The hard-boiled egg captures that perfectly: it's a bit of physical comfort, something you can buy or make, something that's part of the day-to-day wheels of the city that Vimes talks about elsewhere in Night Watch. It's a rejection of revolution, something that Vimes does elsewhere far more explicitly. Vimes is a cop. He is in some profound sense a defender of the status quo. He doesn't believe things are going to fundamentally change, and it's not clear he would want them to if they did. And yet. And yet, this is where Pratchett's Dickensian morality comes out. Vimes is a conservative at heart. He's grumpy and cynical and jaded and he doesn't like change. But if you put him in a situation where people are being hurt, he will break every rule and twist every principle to stop it.
He wanted to go home. He wanted it so much that he trembled at the thought. But if the price of that was selling good men to the night, if the price was filling those graves, if the price was not fighting with every trick he knew... then it was too high. It wasn't a decision that he was making, he knew. It was happening far below the areas of the brain that made decisions. It was something built in. There was no universe, anywhere, where a Sam Vimes would give in on this, because if he did then he wouldn't be Sam Vimes any more.This is truly exceptional stuff. It is the best Discworld novel I have read, by far. I feel like this was the Watch novel that Pratchett was always trying to write, and he had to write five other novels first to figure out how to write it. And maybe to prepare Discworld readers to read it. There are a lot of Discworld novels that are great on their own merits, but also it is 100% worth reading all the Watch novels just so that you can read this book. Followed in publication order by The Wee Free Men and later, thematically, by Thud!. Rating: 10 out of 10

Help your loved ones cope with your death by describing what you would like to happen.
Document how your life has been arranged so that the executor of your Will can find the right documents to inform:
- your bank,
- your mortgage company,
- your energy company,
- your mobile phone company,
- your house and car insurers and the like.
If you've got a complex home setup with servers and other machines which would be unfamiliar to the executor of your Will, then entrust someone else with the information required to revoke your keys, access your machines etc. and then provide the contact information for that person to your executor.
Arrange for your pets to be looked after.
Describe how you would like your belongings to be handled - do you want every effort made to have your clothes and furnishing recycled instead of going to landfill?
Where are the documents for the oven, the dishwasher and the central heating system so that these can be included in the sale of your property?
If there are loans outstanding, make sure your executor or a trusted person knows where to find the account numbers and company names.
What about organ donation? Make sure your executor knows your wishes and make sure your loved ones either agree or are willing to respect your wishes.
Then the personal stuff, what do you want to happen to your social media accounts, your cloud data, your games, DVD and CD collection, your photos and other media? Some social media companies have explicit settings available in your account to describe if you want the data deleted after a certain amount of time, after a notification from some government service or to set up some kind of memorialised version or hand over control of the account to a trusted person.
Next.
