I was installing a program to my android device and realized how much I appreciate the way Guix packages software. It contains only bootstrapable Freedom and Privacy respecting programs and libraries.

It's like a Quality mark: If the package in the repo I'm pretty sure that it's built from source code, it has no blobs, no telemetry and no backdoors. There is no man-in-the-middle in my supply chain.

comp.lang.scheme > An Advanced Syntax-Rules Primer for the Mildly Insane

I'll just leave it here.

Look at what is coming to Scheme ecosystem:

Warming up the meetup!

RDE Meetup #4 will happen on March 13 (less than one week left).

Please fill an optional registration form and send questions and thoughts that bother you to it :)

Everything about #rde, #guix, #scheme and #guile is related (but maybe not everything will be covered on the meetup 🤭 )

I'm curious: is it too geeky stuff to talk about out loud or is it still ok?)

BTW, today I implemented `syntax->list` using a `syntax-case`. I needed it to get a list of values from args pattern variable of (arg1 args ...) pattern.

And only now I realized that I don't actually need it, because #'(args ...) is already a list in Guile.

It solves my previous question about syntax->list I had last week:
https://fosstodon.org/@abcdw/114018596208278873

Today I learned that Racket and Guile represent syntax objects for lists differently.

I don't know yet which one I prefer, because in Guile `syntax` not always returns a syntax-object as one could expect, sometimes it returns a list.

(use-modules (system syntax))
(syntax? (syntax (+ 3 4))) ;; => #f
(syntax? (syntax hi)) ;; => #t

On the other hand TSPL4 book says that #'(+ 3 4) returns a valid list.

Who read RnRS? What does it say for this case?

TIL: There is a builtin completion-preview-mode in recent Emacs.

Guile and RDE Intenships.

RDE applied for GSoC 2025 as a mentoring organization. The results will be on February 27.

I put the list of the project ideas here:
https://trop.in/rde/internship

However, GSoC is not the only way to do the internship. We have some funding contributed by our community members https://opencollective.com/rde and can arrange an internship regardless. Just contact me or drop a message on rde-discuss for details.

#guile #guix #rde #nix #scheme #webassembly #nrepl #vscode #foss #floss

I think RDE is already big enough to apply for GSoC as an organization, so I started to write it! :)

What would you like to see implemented in RDE, Arei, Ares, Guile, Guix in the nearest future?

Maybe VSCode frontend for Arei/Ares Guile Scheme IDE? Or more capable and advanced configuration DSL for RDE?

https://lists.sr.ht/~abcdw/rde-discuss/%3C87msf3rt6i.fsf@trop.in%3E

P.S. Let me know if you would like to mentor one of those projects.

If you curios why lisp is cool, watch this.

In addition to very important mail subsystem refactoring we did, I showed how to decrease time spent building a configuration with Guix Home from 1.5m:

to a fraction of second!

P.S. Today is finally no-technical-issues-good-quality stream! Hack yeah! 🥳

#rde #guix #guile #emacs #lisp

Probably I found the cause of the issue with OBS: the audio/video got desynchronized, robovoiced and messed up probably because of webcamera frame rate being different from overall stream frame rate.

I'm almost certain it fixed now. At least 2 30 minutes test recordings went without an issue!

No more frustration during streams and video recordings? :)

I made a list of email providers some time ago, can be helpful:

I use migadu, afaik they use sieve, not sure if they expose it, but their support is very responsive.

The best WebAssembly lispy language is released. Guile Hoot 0.6.0 is in the wild now.

The most exciting update for me is an implementation of macroexpander, which means eval is around the corner and we can start working on Hoot support for Arei/Ares Guile Scheme IDE soon.

Looks like a huge overhead in terms of performance and complexity for dependency management.

I feel like Unison Lang is moving in right direction on this topic, but I also hope for some more general and widespread improvements in this area.

I was watching a Decentralized Systems course and there was a statement: Git was developed for Linux (a kernel, zero-dependency software) that's one of the reasons why managing dependencies is out of scope (submodules are a trainwreck).

Guix and Nix are basically just an extension of Git, which uses git itself as a database for storing dependency information in plain text format and requires external infrastructure to deal with it.

#guix #nix

@kolev @charliemac @daviwil Is chrome://flags/#enable-webrtc-pipewire-capturer enabled?

@kolev @charliemac @daviwil it's very likely, screensharing works through pipewire.

@kolev @charliemac @daviwil Both browsers support screensharing, in chromium you may need to enable enable-webrtc-pipewire-capturer .

Also, some dbus, pipewire and xdg-desktop portals setup also required. In RDE it should work out of the box.

Do you remember that Guix Social is tomorrow (January 16)?

Guess who is giving a talk on modern and extensible Guile IDE? :)
