(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.
