* about me
GNU Guix contributor since 2013
GNU Guile user and contributor since 2012
Day job: DevOps (AWS, Ruby)
* the four freedoms
0: The freedom to run the program as you wish, for any purpose
* the four freedoms
1: The freedom to study how the program works, and change it so it
does your computing as you wish
* the four freedoms
2: The freedom to redistribute copies so you can help your neighbor
* the four freedoms
3: The freedom to distribute copies of your modified versions to
others
* the four freedoms
a wonderful set of rights, but often *difficult to exercise in
practice*
* common issues
figuring out how to view the exact source for a running program is
tricky
- ??
* common issues
building from source is difficult or sometimes impossible
- non-standard build system
- build scripts make assumptions that aren't true for your system
* common issues
sharing source or binaries has many pitfalls
- dependency hell
- incompatible libraries between systems
- high barrier to entry for common package managers
* freedom: embedded
GuixSD removes many of the common barriers that prevent users from
exercising their four freedoms
* what is guixsd?
<logo>
fully-free GNU/Linux distribution with an advanced package
manager and system upgrade mechanism
* what is guix?
GuixSD's package manager
“functional” package manager
atomic updates and rollbacks
* unprivileged package management
Users can build and install software *without root privileges*
* unprivileged package management
Each user may have one or more “profiles”, a union of many packages.
Use cases:
- Alyssa and Ben use different versions of Emacs
- Alyssa hacks on 2 Ruby projects that require different versions
* experiment without fear
=guix package --roll-back=
=guix system reconfigure=
* inspecting source code
=guix build --source=
* inspecting dependency graph
=guix graph=
<small dependency graph image>
* sharing system configurations
<minimal code example here>
* sharing packages
=guix build -L ~/daves-packages foo=
<minimal package example>
* sharing development environments
=guix environment=
<minimal environment file example>
* sharing binaries
Use =guix publish= to spawn a web server that allows other Guix
users to download the software you've already built
#+BEGIN_SRC sh
guix build \
--substitute-urls=http://guix.dthompson.us:8080 \
hello
#+END_SRC
* reproducible builds
did anyone attend "You think you're not a target? A tale of three
developers..." by Chris Lamb yesterday?
=guix build --rounds=N=
* verifying binaries
=guix challenge=
* customize packages
=guix edit=
=guix build=
* interoperate with other systems
=guix pack=
* extending
GuixSD is essentially a big Scheme library
* literally: embedded
GuixSD now runs on the Beaglebone Black single-board computer!
* the freedom to contribute
GNU Guix is a welcoming community:
we have a *code of conduct* and *enforce* it
we have started seeking new contributors via *Outreachy*
we participate in *Google Summer of Code* every year
oh, and no copyright assignment (in case you were wondering)
* thanks!
