The Infrared-HOWTO (formerly known as the IR-HOWTO) is an introduction to Linux and infrared devices and how to use the software provided by the Linux/IrDA project. This package uses IrDA(TM) compliant standards. Remote Control (RC) via infrared is not the aim of the project, though this topic is partly treated in the HOWTO.
The Linux-Ecology-HOWTO discusses ways to make computers less harmful to our environment and to solve some ecological issues. It explains how to use Linux to save power and consumables like paper and ink. Since it does not require big hardware, Linux may be used with old computers to make their life cycle longer. Games may be used in environmental education and software is available to simulate ecological processes.
IPTables-tutorial is a tutorial which explains how to install and set up iptables and netfilters on Linux. It takes you through a usable example file step by step, and helps you understand its basic functionality. The tutorial currently contains 6 different example scripts that may be used freely under GPL licensing terms.
arch is a modern replacement for CVS, specifically designed for the distributed development needs of open source projects. It has uniquely good support for development on branches (especially good merging tools), distributed repositories (every developer can have branches in their own repository), changeset-oriented project management (arch commits changes to multiple files at once), and, of course, file and directory renaming.
Guido van Robot, or GvR for short, is a minimalistic programming language that provides just enough syntax to help students learn the concepts of sequencing, conditional branching, looping, and procedural abstraction. Its biggest strength is that it permits this learning in an environment that combines the thrill of problem-solving with instant visual feedback.
References for TeX and Friends is an ongoing project which provides a help file for LaTeX (and its friends like ConTeXt, Metapost, Metafont, etc.) using a state-of-the-art source format, DocBook/XML. Various output formats can be generated from the source file. Anyone can write a converter for any desired output format. Because the source file is XML, the easiest way to do this might be to use XSLT.
The PPPOE with Bandwidth Management for OpenBSD Howto is a document which explains how to build an OpenBSD based router for a small flat-sharing community with four residents. The router should manage the available bandwidth fairly between the paying users and their guests. For the residents, it should be possible to use incoming ports for services like Skype or Emule. The howto basically addresses IT professionals with a rough idea of what OpenBSD is about.
