I’ll answer because I’m listed as mentor at
<https://libreplanet.org/wiki/Group:Guix/GSoC-2020>, though honestly, I
think this would have to be someone else or you’ll get very frustrated.
:-)

For both projects, I encourage you to follow the links to get a better
understanding of what the project means.  For project (a), please also
familiarize yourself with substitutes, how they work, and perhaps have a
look at the (guix scripts substitute) and (guix scripts publish) modules
(they may be intimidating at first, so don’t expect to grasp every
detail from day 1, that’s fine!).

For project (b), I’d encourage you to take a look at the Shepherd: it’s
a small project and relatively easy to follow, I think.  If you’re not
familiar with systemd units, you can read
<https://www.freedesktop.org/software/systemd/man/systemd.service.html>
and find what mechanisms are missing from the Shepherd’s API at
<https://www.gnu.org/software/shepherd/manual/html_node/Service-De_002d-and-Constructors.html>.
Pick a specific feature (e.g., “socket activation”), and think about
what it would take to implement it in the Shepherd.

From there, you can go ahead and ask specific questions about things you
don’t understand here or on IRC.

Happy hacking!  :-)
