<h3>1.2. Hydra at nixos.org</h3>
<h3>1.2. About Us</h3>
Hydra is the successor of the Nix Buildfarm, which was developed in
tandem with the Nix software deployment system. Nix was originally
developed at the Department of Information and Computing Sciences,
Utrecht University by the TraCE project (2003-2008). The project was
funded by the Software Engineering Research Program Jacquard to
improve the support for variability in software systems. Funding for
the development of Nix and Hydra is now provided by the NIRICT LaQuSo
Build Farm project.

<h3>2.1. Platform Requirements</h3>
To run Hydra you need a Linux server with at least a considerable
amount of diskspace to store builds. A multi-core machine is not a
waste since Hydra can schedule multiple simultaneous build jobs.
To run Hydra you need a Linux server. For small projects, Hydra can
be run on any reasonably modern machine. For individual projects you
can even run Hydra on a laptop. However, the charm of a buildfarm
server is usually that it operates without disturbing the developer's
working environment and can serve releases over the internet. In
conjunction you should typically have your source code administered in
a version management system, such as subversion. Therefore, you will
probably want to install a server that is connected to the
internet. To scale up to large and/or many projects, you will need at
least a considerable amount of diskspace to store builds. Since Hydra
can schedule multiple simultaneous build jobs, it can be useful to
have a multi-core machine, and/or attach multiple build machines in a
network to the central Hydra server.
