My Reflections and Closing

Being release manager for 20.03 has been a poignant moment for me in being part of NixOS. I had my goals that I set out before I was appointed, but I was really surprised how respected I am in the community. My primary goal was “work collaboratively with all participants in the NixOS project and being supportive of their efforts”. I feel I ✨ shine best in that dynamic in the project, so this really was perfect for me. I hope releasing NixOS has felt better for those involved. With the seeds I’ve planted it should continue to bloom this way.

I’d like to thank Samuel Leathers, my co-release manager, for his congruent effervescence and guidance; Graham Christensen for his organizational encouragement; and obviously every last person I got to work with. Thanks ✌️

In leisure, pause, and experimental grace. worldofpeace.

Heartbleed vulnerability in OpenSSL 09 May 2014
A serious security vulnerability has been discovered in OpenSSL. All stable NixOS releases prior to version 13.10.35708.15a465c are vulnerable. (You can see your current version by running nixos-version.) To upgrade to the latest NixOS version, run nixos-rebuild switch --upgrade. You can verify whether you are safe by running
$ nix-store -qR /run/current-system | grep openssl
If this shows any OpenSSL version prior to 1.0.1g, you may be vulnerable.

ISSRE paper on NixOS-based system testing 18 Sep 2010
The paper “Automating System Tests Using Declarative Virtual Machines” (by Sander van der Burg and Eelco Dolstra) has been accepted for presentation at the 21st IEEE International Symposium on Software Reliability Engineering (ISSRE 2010). It describes how system tests with complex requirements on the environment (such as remote machines, network topologies, system services or root privileges) can be written succinctly using declarative specifications of the machines needed by the test environment. From these specifications we can automatically instantiate (networks of) virtual machines. This is what we use for automated regression testing of NixOS itself. A draft of the paper is available.
Xfce in NixOS 18 Sep 2010
Xfce screenshot NixOS now supports Xfce, a modern, light-weight desktop environment. It can be enabled by setting the NixOS configuration value services.xserver.desktopManager.xfce.enable to true. (Screenshot)

Nix logo 25 Dec 2009
Nix       logo Long overdue, the Nix project finally has a logo! The logo was originally created by Simon Frankau for the Haskell logo competition, who kindly gave us permission to use it for the Nix project. (The snowflake motif is even more appropriate for Nix, because nix is Latin for snow.) Any further modifications are entirely our fault.

KDE 4.2 in Nixpkgs/NixOS 07 May 2009
KDE 4.2 screenshot 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 05 Feb 2009
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.
Linux.com article about Nix 22 Jan 2009
There is an article on Linux.com about Nix: “Nix fixes dependency hell on all Linux distributions”.

The paper “Atomic Upgrading of Distributed Systems” (by Sander van der Burg, Eelco Dolstra and Merijn de Jonge) has been accepted for presentation at the First ACM Workshop on Hot Topics in Software Upgrades (HotSWUp). A draft of the paper is available. It describes Sander’s master’s thesis research on DisNix, an extension to Nix that allows deployment and upgrading of distributed systems from a single declarative description. We will continue this research in the Jacquard PDS project, which has now started. (We still have an opening for a PhD student or a postdoc; please contact us if you’re interested.)

NixOS paper accepted at ICFP! 16 Jul 2008

The paper “NixOS: A Purely Functional Linux Distribution” (by Eelco Dolstra and Andres Löh) has been accepted for presentation at the 2008 International Conference on Functional Programming (ICFP). It describes NixOS in much greater detail than last year’s HotOS paper, and argues why the purely functional style and features such as laziness are important for system configuration management. It also provides some measurements on the actual purity of Nix build actions. A draft of the paper is available.

Website back up 06 Jun 2008

The Nix website was down for a few days due to cooling problems in the server room causing the machine to overheat. These should be resolved now. Apologies for the inconvenience.

Website / SVN repositories moved 25 May 2008

The Nix website has moved to nixos.org (hosted at TU Delft). The Subversion repositories have moved to svn.nixos.org. See this mailing list posting for information about moving existing SVN working copies.

LDTA 2008 paper 05 May 2008

Eelco Dolstra presented the paper “Maximal Laziness — An Efficient Interpretation Technique for Purely Functional DSLs” at 8th Workshop on Language Description, Tools and Applications (LDTA 2008). It’s about caching of evaluation results in the Nix expression evaluator as a technique to make a simple term-rewriting evaluator efficient. Slides are here.

Jacquard grant proposal accepted! 14 Mar 2008

The Jacquard program of NWO and EZ has granted funding for the Nix-related project “Pull Deployment of Services” (PDS), which is about improving the deployment of software and services in complex heterogenous environments.

If you’re interested in these positions, please have a look at this page, and don’t hesitate to contact Eelco Visser or Eelco Dolstra.

New NixOS ISOs 06 Feb 2008

NixOS installer online help New NixOS installation CD images for i686 and x86_64 are available, which is a good thing as the previous ones were already a few months old. The new images are Nix 0.11-based, contain Memtest86+ as a convenience, should support more SATA drives, and show online help (the NixOS manual) on virtual console 7.

Nix 0.11 released 31 Jan 2008
Nix 0.11 has been released. This is a major new release representing over a year of development. The most important improvement is secure multi-user support. It also features many usability enhancements and language extensions, many of them prompted by NixOS, the purely functional Linux distribution based on Nix. See the release notes for details.
Nixpkgs 0.11 released 12 Oct 2007
Nixpkgs 0.11 has been released. See the release notes for details.
OpenOffice in Nixpkgs 10 Oct 2007

OpenOffice screenshot OpenOffice is now in Nixpkgs (screenshot of OpenOffice 2.2.1 running under NixOS, and another screenshot). Despite being a rather gigantic package (it takes two hours to compile on an Intel Core 2 6700), OpenOffice had only two “impurities” (references to paths outside of the Nix store) in its build process that had to be resolved — a reference to /bin/bash and one to /usr/lib/libjpeg.so.

Armijn Hemel, Wouter den Breejen and Eelco Dolstra contributed to the Nix expression for OpenOffice.

NixOS progress report 22 Sep 2007

NixOS screenshot Wine now runs on NixOS! Finally we can run all those legacy applications... Thanks to Michael Raskin for adding Wine and a NPTL-enabled Glibc (which Wine seems to need). This is a nice application of purely functional package composition, by the way: Wine didn’t work with the standard Glibc in Nixpkgs, so we just pass it another Glibc at build time.

In other news, Nix 0.11 and Nixpkgs 0.11 will be released soon.

Commits mailing list 14 Sep 2007

There is now a mailing list (nix-commits@cs.uu.nl) that you can subscribe to if you want to receive automatic commit notifications from the Nix Subversion repository.

HotOS paper on NixOS 08 Jun 2007

Eelco Dolstra presented the paper Purely Functional System Configuration Management at the 11th Workshop on Hot Topics in Operating Systems (HotOS XI). It gives an overview of the ideas behind NixOS. The slides are also available.

NixOS progress report 02 May 2007

KDE logo We now have KDE running on NixOS (obligatory screenshot). Just kdebase for now (Martin Bravenboer already added kdelibs a long time ago so that we could run the wonderful KCachegrind), but it contains all the important stuff (Konqueror, KDesktop, Kicker, Konsole, Control Center, etc.).

In related news, we can safely say that, rumours to the contrary notwithstanding, NixOS is not an April Fools’ Joke.

NixOS progress report 05 Apr 2007
NixOS screenshot NixOS is now almost usable as a desktop OS ;-). We have an X server, a bunch of Gnome packages, basic wireless support, and of course all the applications in Nixpkgs that we had all along running on other Linux distributions. Here are a few screenshots:
NixOS manual 19 Mar 2007
There is now some basic documentation for NixOS.
NixOS for x86_64 23 Feb 2007
NixOS now works on x86_64 machines. A 64-bit ISO is available.
New build farm hardware at TUD 23 Feb 2007

New build farmTo quote Eelco Visser: new hardware for buildfarm at Delft University of Technology has arrived.

Here’s what we have: 5 Intel Core 2 Duo DualCore machines with 1GB RAM, 2 Mac minis with 1,83-GHz Intel Core Duo-processor, another Core 2 Duo a UPS to deal with spikes in power supply, a console with integrated monitor and keyboard switches, a rack with room for a couple more machines.

Here’s what we’re going to do with the goodies. The five Intel machines and the two MacMinis (also Intel) are going to be used to crank at building hundreds of software packages. Using virtualisation we should be able to run builds on multiple operating system distributions. Read more…

Secure sharing paper accepted for ASE 2005 28 Aug 2005
The paper “Secure Sharing Between Untrusted Users in a Transparent Source/Binary Deployment Model” has been accepted at ASE 2005. This paper describes how a Nix store can be securely shared by multiple users who may not trust each other; i.e., how do we prevent one user from installing a Trojan horse that is subsequently executed by some other user?
Service deployment paper accepted for SCM-12 22 Aug 2005
The paper “Service Configuration Management” (accepted at the 12th International Workshop on Software Configuration Management) describes how we can rather easily deploy “services” (e.g., complete webserver configurations such as our Subversion server) through Nix by treating the non-component parts (such as configuration files, control scripts and static data) as components that are built by Nix expressions. The result is that all advantages that Nix offers to software deployment also extend to service deployment, such as the ability to easily have multiple configuration side by side, to roll back configurations, and to identify the precise dependencies of a configuration.
Patching paper accepted for CBSE 2005 17 Mar 2005
The paper “Efficient Upgrading in a Purely Functional Component Deployment Model” has been accepted at CBSE 2005. It describes how we can deploy updates to Nix packages efficiently, even if “fundamental” packages like Glibc are updated (which cause a rebuild of all dependent packages), by deploying binary patches between components in the Nix store. Includes techniques such as patch chaining and computing deltas between archive files.
Paper “Imposing a Memory Management Discipline on Software Deployment” accepted for presentation at ICSE 2004! 16 Jan 2004
The first Nix paper.
