This page presents the software I am working on currently or have been working on in the past. Some of the projects are maintained by others, some are my own. But the thing that is common among them, is that they all are free software. I believe software, which is just a special form of information, wants to be free.

Contributions to other projects


The ADFlib is a free, portable and open implementation of the Amiga filesystem.


Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run.

Debian provides more than a pure OS: it comes with over 43000 packages, precompiled software bundled up in a nice format for easy installation on your machine.


"horst" is a small, lightweight IEEE802.11 wireless LAN analyzer with a text interface. Its basic function is similar to tcpdump, Wireshark or Kismet, but it’s much smaller and shows different, aggregated information which is not easily available from other tools. It is mainly targeted at debugging wireless LANs with a focus on ad-hoc (IBSS) mode in larger mesh networks. It can be useful to get a quick overview of what’s going on on all wireless LAN channels and to identify problems.

  • Fixed unsafe signal handlers.

  • Implemented automatic interface setup using netlink.

  • Fixed many buffer overflow bugs.

  • Refactored, cleaned and fixed code in general.

Linux Kernel

Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance.

Network Block Device

Network Block Device (NBD) is a client/server protocol that emulates a block device (such as a hard disk, a floppy, or a CD-ROM) over the network, thus giving the system the ability to swap over the network, or to use raw network disk space for other purposes.

Python-uinput is Python interface to Linux uinput kernel module which allows attaching userspace device drivers into kernel. In practice, Python-uinput makes it dead simple to create virtual joysticks, keyboards and mice for generating arbitrary input events programmatically.
