This month [hurd hacker] [item]
<http://lists.gnu.org/archive/html/bug-hurd/2011-11/msg00079.html> -- Bouju
Alain submitted a patch to suport cpuinfo in the /proc interface
Richard Braun committed the last patch to mplanetas branch of the slab allocator
work, for integration. http://lists.gnu.org/archive/html/bug-hurd/2011-12/msg00046.html
IRC, freenode, #hurd, 2011-11-14:
Features:
(22:30:39) braunr: there shouldn't be any noticeable difference with the
master branch
(22:30:46) braunr: a bit less fragmentation
(22:30:55) braunr: more memory can be reclaimed by the VM system
(22:31:02) braunr: there are debugging features
(22:31:06) braunr: it's SMP ready
(22:31:15) braunr: and overall cleaner than the zone allocator
(22:31:31) braunr: although a bit slower on the free path (because of
what's performed to reduce fragmentation)
(22:32:42) braunr: but even "slower" here is completely negligible
**New porter box: exodar***

Samuel Thibault identified three easy porting cases: http://lists.debian.org/debian-hurd/2011/11/msg00095.html:
- undefined reference to dl_foo: add -ldl for building
- undefined reference to `main': missing gnu* case in the linking part of configure.ac or .in (pd-* packages are already being handled by their maintainer)
- undefined reference to clock_gettime or crypt: add -lrt or -lcrypt
Richard Brauh added Exodar, a new porter box, which is faster and reliable: exodar.debian.net

As a sidenote, we would like to share a story about real-life debugging with the Hurd:
<youpi> yay GNU/Hurd
<youpi> I have added i_translator check in e2fsck, it was missing
<youpi> I had a volume that was keeping making ext2fs crash
<youpi> with a reproductible scenario
<youpi> could easily work out it was i_translator, then add a check to e2fsck, run it, which indeed fixed, them, and voilà, ext2fs was working again
<youpi> all that on the same machine with *no* system reboot
<youpi> just ext2fs restart :)
<!--bug hurd and debian hurd done-->

Add stuff here? (This is already in q3)
Also …
[our hackers] …
Mainly thanks to …

So if you want to [reason for contibuting to the Hurd],
please [[get in contact|contact_us]] -- and maybe already grab the [[source
code|source_repositories]].

The **GNU Hurd** is the GNU project's replacement for the Unix kernel. It is a
collection of servers that run on the Mach microkernel to implement file
systems, network protocols, file access control, and other features that are
implemented by the Unix kernel or similar kernels (such as Linux). [[More
detailed|hurd/documentation]].
**GNU Mach** is the microkernel upon which a GNU Hurd system is based. It
provides an Inter Process Communication (IPC) mechanism that the Hurd uses to
define interfaces for implementing in a distributed multi-server fashion the
services a traditional operating system kernel provides. [[More
detailed|microkernel/mach/gnumach]].
