Finally got screensharing working in Firefox on Guix + Wayland thanks to @dthompson (and @daviwil and @abcdw !) Here's what I had to do:

- Use this wrapper https://git.dthompson.us/guix-config/tree/dthompson/home/pipewire.scm#n61
- Wrap firefox https://git.dthompson.us/guix-config/tree/dthompson/machines/ikaruga.scm#n158

Thanks y'all!

Lio Novelli and Jurij Podgoršek who run a tech-critical show on a Slovenian student radio station interviewed me and this was aired a couple of days ago:

(Interview starts at 23:22.)

The main topic is #Guix, LLMs, and the Guix Consensus Document process.

@futurile there's a term for this which was coined by Freud: https://en.wikipedia.org/wiki/Narcissism_of_small_differences

#SRFI 273 merged in #Guile #Scheme woohoo!

We all have assumptions about how the world works. One of mine is that passionate, committed, value-based groups are severely at risk of over-focusing on minor differences within the group while missing the wider context.

It always makes me think of this:

Partially, it's natural but overall it's bad! I'm sure I've done it to others, and had it done to me.

Maybe I over-steer, but I try to assume positive intent and try to accentuate what joins us together.

I realized today that “naming and logic”¹ resolves two issues I found for communicating #Guile back in 2013:

A #tutorial for specifically learning Guile #programming and a tutorial to start Guile projects.

The recent emacs-guix release contained the guix-shell feature.

#emacs #guix

Pushed the 0.4.0 release of #haunt to #guix - thanks to @breatheoutbreathein for the PR.

This updated release lets you use html markup inside markdown files which is useful before going to whole way and switching to sxml etc!

Hopefully I can update guix foundation's web site now.

RE: https://infosec.exchange/@david_chisnall/116931490270096063

Some truth in this, and then the extrapolations go a bit far for me.

I agree that much of original Free Software equates 'users' with (advanced) software engineers.

One of the underlying realities that's hard for technologists is that a lot of people don't want to fiddle with their software.

We all have things we care about, and things we don't. Heck, I don't even want to put my own winter tires on or have to upgrade my TV remote.

Even if I have the capacity I may not have the desire.

Most security vulnerabilities have pretty common shapes. But we also have solutions to them:

- Ambient authority! Mitigation: capability security
- Confused deputies! Mitigation: capability security
- Memory exploits: Mitigation: use memory safe languages (Rust and etc if you gotta go low level, though languages with a GC or etc are actually even *safer* because they don't have "unsafe" blocks of code) or use CHERI
- Injection attacks: Use structured representations. Quasiquote or combinator templating is much safer than string templating, for example. Why are we speaking to our databases in sentences? Send them the AST of the query!
- Bad crypto usage: Use standardized cryptography patterns

There are a few others, but even if you just focus on the above, we can simply *eliminate* huge swaths of security issues.

⚠️ Guix security alert ⚠️

Critical security vulnerabilities in the guix daemon and substitute capabilities have been disclosed. ALL users should immediately update.

https://guix.gnu.org/en/blog/2026/guix-substitute-pull-vulnerabilities/

#guix #security #update

⚠ Several critical #Guix daemon vulnerabilities and a minor vulnerability in ‘pull’ and ‘time-machine’ have been fixed: time to upgrade! ⚠
https://guix.gnu.org/blog/2026/guix-substitute-pull-vulnerabilities/

Hey #Guix!

Now `guix pull` and `guix time-machine` supports Git symref. And?

It allows to easily have unmerged Pull-Request.

Consider the fictive PR 567 improving package foo.
And such CI processed this PR with the evaluation 1234.

Then

guix time-machine \
-C https://guix.bordeaux.inria.fr/eval/1234/channels.scm \
-- shell foo bar

where channels.scm file points to refs/pull/567/head.

Done! 🤩

Hey, everyone. I want to spend the next few weeks learning @guix and installing it as a replacement for Debian. The learning curve looks daunting. Where do I start?

I want to do it on real hardware and I have a spare laptop. Sadly @daviwil's nice tutorials appear outdated...?

What I have: an ambition for software freedom and a love of Lisp. What I need: an understanding of the packaging model and (sadly) support for non-free hardware.

Point me to a recent .iso? Point me to a good explainer for noobs? Thanks!

RE: https://toot.aquilenet.fr/@civodul/116793636377732413

Subjectively, #Guix on #Codeberg feels more compact, cozy and lively. Debbugs felt half-abandoned and half-working.

My guess is that the reason in the quality of underlying tech. Forgejo feels more reliable: search in web UI works properly, if the comment sent you are sure it won't be lost, you also see all the changes to tickets immediately, not in a few hours or days.

I miss the full offline archive of all the discussions and patches, but I think the change was for the good.

#Guix #Codeberg #FreeSoftware

@futurile It's been a few months. It's been more of a "me problem" just trying to come up with some kind of good system/home setup that I can work with.

I think the largest hurdle for me is going to be my #emacs setup, which isn't overly complicated now that I've moved away from doom.

Right now I'm all about one step at a time. I want to get Niri and Noctalia setup next.

Practical software freedom with GNU Guix

https://media.ccc.de/v/tdf5-136-practical-software-freedom-with-gnu-guix

#GNU #Guix #OpenSource

Free software gives you freedom, not free beer. But how can you use these freedoms? Its trivial to drink a beer, but getting the source, and the right dependencies, finding how to compile can be a nightmare.

I gave a talk at #TDF5 on how GNU Guix can help you apply your GNU-given freedoms in no time!
