-### GSoC
-
-The last two quarters Jeremie Koenig released the final [report](http://www.gnu.org/software/hurd/user/jkoenig/java/report.html)
-on his GSoC project Java on Hurd along with a summary of his changes
-and the
-[challenges](http://lists.gnu.org/archive/html/bug-hurd/2012-01/msg00062.html)
-he bested. In a similar track, Samuel Thibault
-[merged the slab branch](http://lists.gnu.org/archive/html/bug-hurd/2012-02/msg00010.html),
-finishing Maksym Planetas GSoC work on a better memory allocator.
-
-Also Pino Toscano improved the Hurd implementations
-of [nanosleep](http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00130.html)
-[ptsname_r](http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00122.html),
-[getlogin_r](http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00121.html),
-[getgroups](http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00120.html)
-and
-[sendto](http://lists.gnu.org/archive/html/bug-hurd/2012-06/msg00009.html),
-making it easier to port POSIX programs, and Samuel Thibault
-[added Thread Local support (TLS)](http://lists.gnu.org/archive/html/bug-hurd/2012-05/msg00046.html),
-further improving the standards conformance of the Hurd and paving the
-way for C++11x.
-
-### Barrier of Entry
-
-Samuel Thibault, Ludovic Courtès and Thomas Schwinge reduced the
-barrier of entry into hacking the Hurd.
-
-As part of this, Samuel prepared
-[dde in incubator](http://lists.gnu.org/archive/html/bug-hurd/2012-02/msg00037.html),
-making about half the Linux network drivers compile on the Hurd. Also
-he added the
-[netdde debian package and testing notes](http://lists.gnu.org/archive/html/bug-hurd/2012-02/msg00038.html).
-
-Ludovic added
-[a continuous testing framework](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00019.html)
-using a Nix-based GNU QEMU image. Thanks to his work, we now have
-[automatic tests](http://hydra.nixos.org/jobset/gnu/hurd-master)
-([background](http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00104.html)).
-
-Thomas on the other hand
-[moved](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00063.html)
-the translators
-[cvsfs](http://git.savannah.gnu.org/cgit/hurd/incubator.git/log/?h=cvsfs/master)
-and
-[smbfs](http://git.savannah.gnu.org/cgit/hurd/incubator.git/log/?h=smbfs/master)
-into the incubator git repository, as well as
-[libfuse](http://git.savannah.gnu.org/cgit/hurd/incubator.git/log/?h=libfuse/master),
-reducing the barrier of entry to improving them, so integrating cvs
-and samba in the filesystem and using FUSE translators can be
-stabilized more easily. Also he
-[improved the Hurd build system](http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00087.html),
-making it easier to get in:
-
- “running autoreconf is all you need”
-
-Additionally Roland McGrath
-[merged many libc changes](http://lists.gnu.org/archive/html/bug-hurd/2012-05/msg00033.html)
-for upstream inclusion, reducing the maintenance load for getting
-recent improvements of libc.
-
-### The Core of the Hurd
-
-Ludovic Courtes, Maksym Planeta, Samuel Thibault and Richard Braun
-took a dive into the core of the Hurd. Ludovic
-[fixed invalid port deallocation in `symlink'](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00013.html)
-and
-[made console-run resilient against missing /dev/console](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00002.html). Maksym
-[tested the performance of tmpfs](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00040.html),
-showing a speedup from 22s with ramfs and ext2fs to 16s with tmpfs for
-apt-get calls, showing the possible wins due to going deep. An obvious
-usecase for tmpfs are
-[faster Hurd LiveCDs](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00050.html). Samuel
-made it easier to dive in by
-[improving debugging in GNU Mach](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00032.html). The
-debugger is now aware of the difference between kernel space and user
-space. This should substantially reduce the development time for
-features in Mach by giving
-[nicer stack traces](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00047.html). And
-in the deepest core of the Mach, Richard improved memory mapping
-[with a red-black tree](http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00109.html),
-which should speed up memory access.
-
-### Porting
-
-As in the previous quarters, we also saw lots of ported packages,
-including Richards work on
-[libpcap](http://lists.gnu.org/archive/html/bug-hurd/2012-01/msg00059.html)
-which brought wireshark and
-[pcap_inject](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00000.html)
-for easier network testing,
-[libtool](http://lists.gnu.org/archive/html/bug-hurd/2012-02/msg00023.html)
-thanks to Samuel Thibault and Peter O'Gorman,
-[gnat](http://lists.gnu.org/archive/html/bug-hurd/2012-03/msg00060.html)
-by Svante Signell for Ada support (a language used in many
-mission-critical applications such as automotive and aerospace,
-offering features like strong typing, modularity, run-time checking
-and parallel processing), and
-[iconx](http://lists.gnu.org/archive/html/bug-hurd/2012-06/msg00004.html)
-thanks to Samuel Thibault, which fullfills a requirement of tests for
-many packages, among them glib - and allowed Svante Signell to port
-the literate programming language noweb and ifupdown. Also Thomas
-DiModica
-[merged](http://lists.gnu.org/archive/html/bug-hurd/2012-06/msg00018.html)
-the cthreads to pthreads patch and
-[added a branch for it](http://lists.gnu.org/archive/html/bug-hurd/2012-07/msg00087.html)
-to make it easier to work on getting Hurd to use the more current
-pthreads. For details, see Richards report about running
-[Hurd without dependency on cthreads](http://lists.gnu.org/archive/html/bug-hurd/2012-08/msg00062.html).
-
-And now, as a final note, we want to share a story about real-life
-debugging with the Hurd; IRC, freenode, #hurd, 2012-03-02:
-
- <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 :)
-
-
-So if you want to experience enjoyable debugging of code deep in the core of your system,
-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]].
