RMS on "The Cloud:"


Do we really want to be "cloud?"  That seems contrary to Freedom.

mentoring organizations about Hurd projects in their context.

Not a GSoC task, but Gabriele, Justus, Petter have recently been working
on such stuff,
And, we might be getting something similar via Guix,
Nevertheless still suitable to propose as a Debian project?
for Debian GNU/Hurd?

I'm somewhat interested in seeing Hurd running in "the cloud", à la
and similar.  I can't really tell what it takes on the Hurd side to do
that -- as I once read, Amazon EC2 is based on Xen, so maybe that's "just
working already".  Then, a pile of infrastructure on top of that.  Would
that be a suitable project for Debian, <https://wiki.debian.org/Cloud>?
This project seems of a similar style:
<https://wiki.debian.org/SummerOfCode2014/Projects/bootstrap-vz>?  And/or

Too much of a toy to be a suitable project?  Or, given that MIG has a
simple grammar, it'd indeed be a useful project for a beginner?

Or, some tracing thingy with LTTng,
<http://www.google-melange.com/gsoc/org2/google/gsoc2014/lttng>, or
SystemTap?  Brush up on

Language bindings, RPC interface for GNU Guile?

Language bindings, RPC interface for Steel Bank Common Lisp,

Samba, <http://www.google-melange.com/gsoc/org2/google/gsoc2014/samba>:
smbfs translator?

Ceph, <http://www.google-melange.com/gsoc/org2/google/gsoc2014/ceph>:
ceph translator?

any GNU Mach things, virtio, or something else?

Anything with rump kernels, <http://www.netbsd.org/docs/rump/>?  Or, do
we first have to get a clearer picture ourselves what will be possible to
do there?

(X.org indeed are participating,
<http://www.google-melange.com/gsoc/org2/google/gsoc2014/xorg>, but we're
not currently present on their project ideas list.)

We once had the idead that we'd like a userspace version of GRUB for
booting subhurds.  Is this an idea worth following as a GSoC project?

And finally, a bit of an "obscure" one: implement for GNU Hurd something
like the Eudyptula Challenge, <http://eudyptula-challenge.org/>, or
Matasano Crypto Challenges,
<http://www.matasano.com/articles/crypto-challenges/>, that is, a remote
"teaching" system.  The GSoC student would indentify a suitable set of
features to showcase the Hurd's unique as well as general concepts, and
implement a learning system for others to use.
