@khinsen Makes a lot of sense, thanks! Now I can see the connection with ActivePapers, the Glamorous Toolkit, and other exciting software developments you’ve made.

#Guix

@cwebber Having had several demos of BLUE and blue.el (!) by @shepherd, including a working port of the Shepherd from Autoconf/Automake to BLUE at the bar the other day (where I was tasked with discovering BLUE by myself), I’m also very enthusiastic!

@janneke

@janneke Fun. Didn’t know about stepmake, but I do remember about your work on GUB (?) which I guess was more in package management territory, right?

@shepherd @cwebber

Souvenir from the #Guix Days (pictures by @levenson).

Yes, we actually had a release cake (vegan!) to celebrate the hard work of the release team on 1.5.0!

Too bad one of the team members couldn’t make it. We had to eat their share of the cake. :-)

Kudos to everyone who made this event so pleasant: @futurile, Tanguy, @pjotrp, and @indieterminacy for the logistics, Olivier who was caught off-guard and ended up being the official facilitator with help from @cbaines, our hosts at ICAB, and all the participants! ♥

I’ll definitely come back next year. :-)

📺 My talk in the #HPC track at #FOSDEM, “Package management in the hands of users: dream and reality” 👇

#Guix

What a day! Those Guix Days were awesome and insightful, as always.

Cherry on the cake: this night, I saw a Framework laptop running Guix System boot in 17 minutes (seventeen minutes), I went through a reverse job interview (successfully, but I almost failed), and I added a committer to the Shepherd repo (expect cool things).

A discovery of these #Guix Days, thanks to @janneke, is Germ:

This blog post is the #bootstrapping equivalent of “BTW I wrote an operating system last week-end.”

And how @tsyesika touching on #Guile development outside of #Emacs—which is kinda crucial: #Guix, #Guile, #Spritely folks certainly want to reach out to people not into it!

@tsyesika Wait wait wait, not only did Jessica implement a VSCode plugin to properly indent Scheme, we also get a live demo of it!

@tsyesika Regarding the online copy of manuals, check this out 👇

It won’t be as good as Racket’s (yet), but at least it brings syntax highlighting and hyperlinks on identifiers in Scheme snippet, and cross-manual links that are not 404. :-)

Glad to see a senior Guile developer explain that ‘pk’ is their primary debugging tool. We should organize a ‘pk’ gathering someday.

Wonderful talk by @cwebber on why “Lisp i clay”, to share with all the paren-skepticals!

#Guile #Scheme #Lisp

Excited to be at the #Spritely talk on leveling up the #Fediverse!!

#FOSDEM

Very convincing presentation of git-history(1) (among other things) in Jansson this morning. Particularly neat is automatic rebasic of dependent branches when rewriting history.

Here I am, in Brussels, still preparing my Sunday talk, having already met a fellow hacker and ready to have a good time with others!

Challenge for the upcoming days: get enough rest to remain operational till Wednesday. :-)
