Nix

Nix is a purely functional package manager. It allows multiple versions of a package to be installed side-by-side, ensures that dependency specifications are complete, supports atomic upgrades and rollbacks, allows non-root users to install software, and has many other features. It is the basis of the NixOS Linux distribution, but it can be used equally well under other Unix systems. Read more…

KDE 4.2 in Nixpkgs/NixOS	2009/4/7
We now have a fairly complete set of KDE 4.2 packages in Nixpkgs and NixOS. Previously we had KDE 3.5, but it was rather incomplete: just kdelibs and kdebase. Now we have all that desktop goodness, such as kdemultimedia, kdenetwork and kdegames. You can enable KDE 4 in NixOS by setting the services.xserver.sessionType option to kde4. Thanks go to Yury G. Kudryashov, Andrew Morsillo and Sander van der Burg for doing the hard work on adding KDE 4 to Nixpkgs. (Screenshot 1, screenshot 2.)
Hydra	2009/1/5
Nix and NixOS releases are now built in Hydra, the new Nix-based continuous build system. Hydra replaces our old Nix-based build farm, which will be phased out soon. There are several advantages over the old build farm: the build tasks for a project are scheduled and published separately, so that for instance a (fast) tarball build doesn’t have to wait for a (slow) Cygwin build; build results are stored in a database, which will enable all sorts of interesting queries; better error reporting; a better web interface; and much more. We have written a draft paper about Hydra. There are some instructions available about how to set up your own Hydra server.
