FOSDEM 2019

Hello everyone,

It's that time of the year again we need to start organizing about
FOSDEM. We have a deadline for the 20th of September[1] to apply for a
devroom. We also need to start looking for a place for this year's
fringe event!

I created a libreplanet page[2] to start writing possible talk ideas in
case we get a devroom.

We also need to write a proposal for our devroom application. The last
year's proposal should be a good start. (attached) We should also talk
with the Lua people in case we can share a devroom with them.

Start sending ideas people!! This FOSDEM is going to be awesome!

Thank you,
Manolis

* Devroom name:

GNU Guile — the official extension language for the GNU Project

* Devroom description:

The [[https://www.gnu.org/software/guile/][GNU Guile]] programming
language is dynamically typed and
multi-paradigm.  Guile allows for functional approaches,
object-oriented programming using GOOPs (a CLOS-like object system),
logic programming, and system scripting.  Guile is suited for
meta-programming and has a powerful macro-system which allows users to
change the language on the fly.  Guile features a growing set of
bindings and libraries for libssh, git, json, sdl, opengl, cairo, gtk,
redis, SQL, etc.

GNU Guile is the preferred extension system for the GNU Project which
features an implementation of the Scheme programming language, a
dialect of Lisp with a mature community. GNU Guile is continually
improved where recent milestones were a new compiler infrastructure, a
virtual machine implementation, a switch to the Boehm-Demers-Weiser
garbage collector and many improvements to the Guile Scheme language
itself.  Major performance improvements were demonstrated at FOSDEM
with a new optimizing compiler which is now part of the recent 2.2
release. Other recent additions are a "sandbox" facility that can run
code from untrusted users and improved support for immutable data.

The use of GNU Guile is growing.  Amongst the current applications
written in Guile, there are AO, a new 3D CAD engine; Skribilo, Artanis
and Haunt, (web) templating engines; Sly, a gaming engine; and (of
course) GNU Guix, a functional software deployment manager for the GNU
Project which also underpins GuixSD a new functional GNU/Linux
Distribution. GNU Guix is a rapidly growing project that distinguishes
itself by creating 100% reproducible software installations generated
by a hackable system.  GNU Guix is an important driver for GNU Guile
development because the massive project puts large demands on GNU
Guile. In the last year GNU Guix has grown 40% from approx. 200K to
280K lines of source code whereof an amazing 260K lines are written in
GNU Guile!  GNU Guix has great support for developers, including the
GNU Emacs eco-system and GNU Guile (of course), but also for Java,
Clojure, Perl, Ruby, Python, Haskell, GO, D, Erlang, and Elixir.

Interesting spin-offs of Guix are a Guile make replacement,
virtualization of development environments, the Shepherd and a new
approach to system service integration; and the bootstrappable.org
effort with Mes and Nyacc, a project for creating bootstrapped build
systems from source only (also presented at FOSDEM last year) which
tries to revert the current trend of bootstrapping build systems with
binaries. Bootstrapping from source is crucial to free software
distribution.

Other noteworthy GNU Guile applications include GNU Lilypond, GnuCash,
and GNU Mcron a cron-compatible task scheduler.  More GNU Guile projects
can be found at https://en.wikipedia.org/wiki/GNU_Guile and
https://www.gnu.org/software/guile/libraries/.

The devroom will provide at least the following content with a focus
on software development:

- An introduction to GNU Guile
- Guile Next: Latest developments in GNU Guile
- Concurrent programming with Fibers and 8sync
- Compiler implementation in Guile
- Web frameworks with GNU Guile
- Shepherd the systemd replacement
- GNU Guix
    + Latest GNU Guix developments
    + Tooling for development environments
    + Whole-system deployment, and distributed deployment
- Guile and network programming
    + Dealing with concurrency in networking applications
    + Application performance
- The Guile community
  + Freedom can be expressed in multiple ways
  + Encouraging and mentoring newbies; encourage diversity
  + Tutorials and documentation

A complete list of currently considered talks can be found at
https://libreplanet.org/wiki/Group:Guix/TalkProposals.

The purpose of the dev room is to present latest developments in Guile
itself, to share exciting news about, and demo applications using Guile,
to provide a space to meet with fellow hackers and enthusiasts, and to
grow the Guile community.

* Why should FOSDEM accept this proposal?

GNU Guile is a core component of the successful and long running GNU
project, and today the fresh Lisp language is being discovered by a
new generation of programmers.  In 2016 we had our first half day
Guile devroom at FOSDEM and it was a great success: the devroom was
full for every talk!  In 2017 we were lucky to get a full day which
was also full all day. FOSDEM gives a great impulse by getting
developers together and projects like MES started there.  Both years,
together with the LUA devroom we overlapped a session where we
discussed the future of small languages (we are interested in sharing
the devroom with LUA again if we can not have a full day).

This would be the second opportunity for GNU Guile related projects
world-wide to meet at FOSDEM.  Similar to last year, we will invite
speakers from other projects that are loosely coupled to the Guile
environment (e.g. projects that use Guile purely as an extension
language, such as gdb and Lilypond).

In short, having this devroom will allow us to dig deeper into the
details of language design and reproducible software in particular,
whilst giving back to the free software community as a whole.

Thanks for getting the ball rolling!

If we base our application on this proposal I think we should make these
changes:

- mention the work on adding JIT

- mention “Chickadee” instead of “Sly” (Chickadee is a general purpose
  game development toolkit that sees continued development, whereas Sly
  is specifically for game development with functional reactive
  programming)

- change “AO” to “libfive Studio” (the project has been renamed)

- add “R” to the list of languages for which Guix has great support

- “Guile make replacement”?  Is this an actual thing?

- use HTTPS for http://bootstrappable.org

Obviously, the list of topics would need to change (that depends on the
proposals for talks) and references to “last year” would need to be
updated.

We should also figure out if there are enough people in the extended
Guile universe who would be willing to give a talk.  If we don’t have
enough topics we might want to share the room with other communities
that have some links to us (e.g. other Lispy languages, or “small”
languages, etc).

Under the topic of encouraging newbies (and tangentially in the topic
of increasing diversity), I could do a talk about my experiments in
writing interactive fiction in Guile.  I have had a goal of making
something as simple to use as the Twine interactive fiction engine.  I
posted that on the wiki for now.

Yes definitely!  This will be Guile 3, so we can call it "Just-in-time
code generation for Scheme: Speed for free in Guile 3" or something.
I'd be happy to give this talk.

Hi.

In your list, you mention "encouraging newbies" and "encouraging
diversity".  In that category, I could do a talk on my experiments in
writing interactive fiction in Scheme.  Interactive fiction tools like
Twine have been a first step for many young programmers, and tools
like Twine have been adopted by many young LGBT authors.  If we could
make the syntax simple and obvious enough, maybe an interactive
fiction tool in Guile could be useful.

But the technical challenge of making a simple tool has been
surprisingly complicated in interesting ways.

I went ahead and threw that up on the libreplanet wiki for now

Mike Gran

Who wants to come to a separate 2 day GNU Guix event?

That is the Thursday Jan 31st and/or Friday Feb 1st right before
FOSDEM. I.e., 4 days of hacker nirvana.

FOSDEM is really great. Look at last year's schedule for Saturday

  https://archive.fosdem.org/2018/schedule/day/saturday/

Last year we had a 1 day event with about 25 people before FOSDEM.
See

  https://libreplanet.org/wiki/Group:Guix/FOSDEM2018

If you intend to come and/or want to speak please add your name and
proposed title to the new page at

  https://libreplanet.org/wiki/Group:Guix/FOSDEM2018

Alternatively, reply here or mail me privately so we can keep a tally.

Please do so because we need to find a venue again on a first come
first go basis if we run out of seats.

Pj.

I plan to be there for the 2 days of Guix and the 2 FOSDEM days.

Please also let us know (privately, if you prefer) if your attendance
would be dependent on having on-site childcare.

I copied and adjusted the text from last year’s page.

Anyway, feel free to add your name if you would come, and ideas of talks
or hacking sessions we may have, so we can start planning!

Thanks,

Thanks for everyone is doing organizing, especially Manolis for kicking
this off!

I added a talk topic: "A Guiler's Year of Racket".  I think there's a
lot we could learn from our fellow friends in Racket-land, and I'd like
to share some of that!

I'm trying to convince my wife she should come for FOSDEM, not sure how
likely it's going to be.

Without checking with the wife, I should be good for at least one day of
GUIX hacking.

Just a gentle reminder. Please sign up if you haven't and you want to
attend. For the main room we have to cap at 35 people. We still have
room!

https://libreplanet.org/wiki/Group:Guix/FOSDEM2019#Attendees

Note also it is possible to stay the night at ICAB. It is actually
pretty nice though the plumbing can be a bit noisy :)

The announcement page is updated to the latest:

  https://libreplanet.org/wiki/Group:Guix/FOSDEM2019
 
Do register if you intend to come to the GNU Guix days. We will limit
the audience to 40 persons.

For those of you travelling from far away, there are many places you
can stay in Brussels. There are also rooms at the ICAB where we are
hosting the two day event. Some of us will stay there again and even
though it is not luxurious it is decent and pretty convenient.

We have an exciting program for the minimalism devroom at FOSDEM, see 

  https://fosdem.org/2019/schedule/track/minimalistic_languages/

We also have two GNU Guix days before FOSDEM. The idea is to break out
into working groups during those two days. I have added a few ideas
here:

Feel free to add your favourite topics! If you want to attend be sure
to add your name. We can't allow more than 40 people.

Gotta say I love the program!

I was thinking that maybe I could present Next browser
(https://next.atlas.engineer), e.g. how to hack it and how it's implemented.
But I'm wondering if it's not too off topic.  The main link here is that it's
written and hackable in Lisp (Common Lisp).  What do you think?

Dear,

At Paris' Guix' meeting in December, I really enjoyed the after lunch
session: quick demo about tools.
Janneke showed how they uses Emacs as Window Manager.
Ricardo showed some tricks with git-worktree.
Ludo showed guile-guix stuff---I do not remember well.

Reproducible idea? ;-)

Definitely.  That’s the so-called “skill share” session inspired by the

would be a good fit for that.
