GNU Guix: Meet Guix at FOSDEM
It’s that time of the year again: next week is
FOSDEM time! As in previous
years, many Guix people will
be in Brussels. Right after FOSDEM, about sixty of us will gather on
February 2–3 for the Guix Days!

First things first: Guix presence at FOSDEM. On Saturday, January
31st:
- In Name resolution in package management systems — A reproducibility
perspective,
Gábor Boskovits will look will look at how several package managers
refer to packages and how this affects reproducibility.
On Sunday, February 1st, the Declarative & Minimalistic Computing
track
will once again be a Guile & Guix lair. The whole track is amazing,
with top-notch talks and speakers; particularly relevant to Guix and
Guile hackers are the following:
- Sergio Pastor Pérez will give a talk entitled BLUE — A generic
build system crafted entirely in
Guile. There
are clear connections with Guix but BLUE could well become the new
standard build system for Guile developers! - In Modern Development Tools and Practices for
GNU Guile
Andrew Tropin will talk about live programming at the REPL, in
particular with the Ares/Arei interactive development environment. - On the same theme, Jessica Talon of
Spritely will talk about Guile
development outside of
Emacs—addressing
a real need of Guile and Guix outreach efforts. - In Lisp is clay: the power of composable
DSLs,
the inimitable Christine Lemmer-Webber will talk about this Lisp
foundation that makes Spritely and Guix so powerful. - David Thompson (also of Spritely!) will talk about Functional
reactive programming with
propagators,
which sounds like an exciting topic for any functional programming
person and any programmer who’s worked on user interfaces and other
kinds of “reactive” programs. - Simon Josefsson will talk about Guix Container Images — and what
you can do with
them,
showing how to add Guix container images to registries and how to
use them in continuous integration and continuous delivery (CI/CD)
pipelines.
You can have more Guix bliss on Sunday afternoon:
- In a talk entitled Package management in the hands of users: dream and
reality,
I (Ludovic Courtès) will reflect on successes and failures bringing
package management to HPC supercomputer users. - Samuel Thibault will share Updates on GNU/Hurd
progress,
which includes Guix goodness and good news for a practical
empowering operating system.
Guix Days will take place on Monday and Tuesday right after FOSDEM,
at our usual
venue.
Sixty people already
registered, which
is our maximum capacity—don’t just show up and hope for the best.
As always, this will be unconference style: we’ll make the program as
we go, discussing hot topics such as the crowdfunding
campaign,
an update on Guix Foundation, processes
and governance, as well as the more technical topics we’re fond of.

This year marks the tenth anniversary of the Guile/Declarative &
Minimalistic Computing
track, and the
eighth Guix Days.
Shout out to our friends Pjotr Prins and Manolis Ragkousis, who have
spearheaded the two events during all these years, and to all the
volunteers who helped them on the way! This yearly Brussels gathering
has been instrumental in building, shaping, and strengthening our
community; to those who can be present, it’s the energizing and
refreshing moment of the year. To Pjotr, to Manolis: thank you!
