The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system that we have created is called Debian.

Debian systems currently use the Linux kernel or the FreeBSD kernel. Linux is a piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. FreeBSD is an operating system including a kernel and other software.

However, work is in progress to provide Debian for other kernels, primarily for the Hurd. The Hurd is a collection of servers that run on top of a microkernel (such as Mach) to implement different features. The Hurd is free software produced by the GNU project.

A large part of the basic tools that fill out the operating system come from the GNU project; hence the names: GNU/Linux, GNU/kFreeBSD and GNU/Hurd. These tools are also free.

Of course, the thing that people want is application software: programs to help them get what they want to do done, from editing documents to running a business to playing games to writing more software. Debian comes with over 29000 packages (precompiled software that is bundled up in a nice format for easy installation on your machine) — all of it free.

It's a bit like a tower. At the base is the kernel. On top of that are all the basic tools. Next is all the software that you run on the computer. At the top of the tower is Debian — carefully organizing and fitting everything so it all works together. 

The BSD most widespread on personal computers is FreeBSD. It has the best hardware support and is the most optimised for the i386 (x32) and AMD64 (or Intel64) architecture. It has the most features and focuses most on ease-of-use. It also has the largest Ports Collection, with more than 23.000 applications available. FreeBSD does not consider itself a pure server operating system anymore. It now has much better desktop support, with significant improvements in sound and graphics capability, USB, Firewire and WLAN support, helping users from Windows and Linux with graphical user interfaces. FreeBSD supports a lot of platforms, including AMD64, EM64T, Alpha, Itanium (ia64), PowerPC (Apple), SPARC64 etc. FreeBSD is the most widespread BSD with the largest user base and most committers and has very good SMP support. Today a project has emerged especially for desktop users: PC-BSD, giving users an easy way to install, configure and update their systems. There are other projects based on FreeBSD for firewalling (m0nowall and pfsense) and NAs (FreeNAS) FreeBSD is used for a lot of servers in companies and enjoys much support from well-known companies like Dell, Yahoo!, Juniper and others.

Cooperation works only by providing mutual help. Hence, we are very grateful of the commitment our partners show und we try to give our best to give them something back inreturn. We believe, that interoperation is the fundamental idea of free software and that it must be supported to promote the free software movement.

Free patterns for free mascots

During Linuxtag 2011 the first Stricktux ("knitted tux") was made. And at FrOSCon 2011 we had a knitters' meetup during the slot "Free Software Knitting - Stricken für Geeks und Nerds".

Since then some add-ons for the Stricktux were published as well as patterns for several other mascots of free software and related projects and institutions.

  subtle is a manual tiling window manager with a rather uncommon approach of tiling: Instead of relying on predefined layouts, subtle divides the screen into a grid with customizeable slots (called gravities). For better understanding, the default config uses a 3x3 grid and maps each gravity to one key of the numpad. With those keys, windows can be moved directly to the desired gravity - the same can be done with tagging rules in the config.

Another unique concept is the strict tagging: Unlike other tiling window managers, subtle doesn't allow weak tagging and always maps windows to virtual desktops (called views) with matching tags, regardless of the current active view.
