+A quarter of the Hurd: *Arch Hurd with DDE*, *Debian boxes*, *GHM talk* and
+*GSoC: Java*.

+
+In the third quarter of 2011, the Arch Hurd hackers [packaged DDE (Device
+Driver Environment)](http://www.archhurd.org/news/22/), so a subset of the
+Linux 2.6 device drivers can now easily be run as user-space processes on Arch
+Hurd, replacing GNU Mach's in-kernel device drivers. (This has been possible
+before, too, but involved several [[manual steps|hurd/dde/guide]].) At the
+time of writing, our DDE port supports several network cards, while for other
+driver types we will need to add further generic infrastructure. Also, Arch
+Hurd had [a booth at
+FrOSCon](http://www.froscon.de/en/exhibitors/projekte.html#c1413) and [released
+a new Arch Hurd LiveCD](http://www.archhurd.org/news/24/), so new users can
+easily test the current state of the Arch flavor of the Hurd.
+
+Richard Braun contributed additional GNU Hurd instances: [[a *Debian buildd*, a
+*Debian porterbox*, and a *public Hurd box*|public_hurd_boxen]]. Especially
+the last one is important for *you*: after requesting an account, you can use
+it to test the Hurd without any own setup.
+
+Samuel Thibault sent a new [Bits from the Debian GNU/Hurd
+porters](http://lists.debian.org/debian-devel-announce/2011/07/msg00002.html)
+to keep the Debian folks up to date with our progres. And it is quite good:
+thanks to the relentless work of our porters, you can now use [70 % of all
+Debian packages with the Hurd](https://buildd.debian.org/stats/graph-big.png),
+so we're getting closer to [the goal of finishing a Release Canditate in time
+for Debian Wheezy](http://wiki.debian.org/Debian_GNU/Hurd). If you can, for
+example, port Debian packages and want to help the Hurd, this is the perfect
+time to get in contact and [port your favorite missing
+package](http://www.debian.org/ports/hurd/hurd-devel-debian) to the Hurd.
+
+A different kind of status update was delivered by Samuel Thibault on the [[GNU
+Hacker Meeting (GHM) in Paris|community/meetings/ghm2011]]. We hope you enjoy
+watching the video of the {{$community/meetings/ghm2011#thibault_hurd}}. He
+nicely explains how the simple yet powerful concept of a [[hurd/translator]]
+gives power to a system's less-priviledged users (that is, without `root`
+access), without any security implications, and how [[hurd/subhurd]]s and
+[[hurd/neighborhurd]]s compare to Linux containers. *It's all about [freedom
+0](http://www.gnu.org/philosophy/free-sw.html)*.
+
+On the technical side, Thomas Schwinge improved the technical documentation of
+the [[I/O path|hurd/io_path]] when translators are involved, to make it easier
+for new developers to understand how all the different system components
+interact. Amongst others, Guillem Jover, Fridolín Pokorný and Jonathan
+Neuschäfer
+[sent](http://lists.gnu.org/archive/html/bug-hurd/2011-08/msg00184.html)
+[many](http://lists.gnu.org/archive/html/bug-hurd/2011-08/msg00093.html)
+[patches](http://lists.gnu.org/archive/html/bug-hurd/2011-08/msg00030.html) for
+GNU Mach, improving stability, fixing memory leaks and generally cleaning up
+the code.
+
+Maksym Planeta finished a project he has been doing as a university task:
+replace GNU Mach's old zone memory allocator with a new [[!wikipedia
+slab_allocation desc="slab allocator"]] written by Richard Braun, who also
+mentored Maksym during the project. [This
+allocator](http://git.savannah.gnu.org/cgit/hurd/gnumach.git/commit/?h=mplaneta/libbraunr/master&id=59c9da87375ad3c8401890ecd4f7f101093f2463),
+apart from being overally cleaner than the zone allocator, is meant to waste
+less memory than the zone allocator (less fragmentation and more memory can be
+reclaimed by the VM system), there are debugging/inspection features, and it's
+SPM-ready, thus readily usable once we get up-do-date SMP support in GNU Mach.
+It is now being tested and integrated.
+
+And last but definitely not least, Jérémie Koenig finished his Google Summer of
+Code project to [[improve Java support on GNU Hurd|user/jkoenig/java]]. All in
+all, he also [improved the Hurd signalling
+code](http://lists.gnu.org/archive/html/bug-hurd/2011-06/msg00073.html), ported
+OpenJDK and began designing and creating a [library for Java bindings for Mach
+and Hurd](https://github.com/jeremie-koenig/hurd-java) which already allows
+writing a [Hello World translator in
+Java](https://github.com/jeremie-koenig/hurd-java/blob/master/HelloMach.java).
+It is still pretty low-level, but it paves the way for extending the core of
+the Hurd with Java, which is one of the benefits of the Hurd's distributed
+multi-server architecture: different components of the operating system can be
+written in different programming languages; not just
+[C](http://www.gnu.org/software/hurd/hacking-guide/hhg.html#An-Example-using-trivfs),
+but also C++, [[Common Lisp|user/flaviocruz]], and now Java -- and more to
+come.
+
+So if you want to help getting the Debian GNU/Hurd Release Candidate done, or
+want to dig deep into DDE to have more device drivers running as user-space
+processes, 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]].
