• Linux QoS I spent about 5 years programming with M$ Windows (MSW) and I can say that for programmer the Linux is heaven (you can find some of my MSW projects bellow).
  After 4 months experience with linux I started to hack the kernel. In our company we needed to distribute IP traffic among our customers so that I enhanced linux's QoS code.
• Connbytes iptables match You need to reclassify long downloads lo low-prio band ? Here is your tool.
• Accelerometer device When I was looking what is vibrating in my car I decided to design inteligent three axis accelerometer to measure it. Here it is along with nice measured spectrogram.
• Linux callgraph I have idea for new VM algorithm (unfortunately noone want hear about it :-) and wanted to understand current one. So I did a proggie for it.
• My braindump of The best VM for Linux How to find the best VM page allocation algorithm here.
• How to mitigate DDoS idea here.
• Linux trustees changes I hacked trustees code to make them independent of syscalls. See here.
• Apache patches See here.
• MS Windows FastCon When I worked with NT server which acted as WWW server (currently we switched to Apache on Linux) I needed ability to administrate it from my home.
  Because there was no working remote console tool (except slow one from resource kit) I wrote one myself. The tool is called FastCon and is free software.
• Graphics At school I played with adwanced graphics algorithms, you can see some results here :-)
• Supermicro MoBo WDT little reverseengineering of Watchdog Timer.
• Packages I created for Debian.

Something about me: After I have finished a High (electrical) School, the next step in my education was Czech Technical University (CVUT). Unfortunately I did not finish it, I had to drop it after three years. My specialization at CVUT was computer graphics. Our team developed very effecient method of near-optimal BSP (binary space partitioning) tree building. We used 3D interval arithmetic along with modified radix-sort method.
You can read my articles about raytracing visualisation in czech Chip magazine (1996 - "Kouzelne Paprsky").
Meanwhile I gained an experience in PC programming, especially in Win32 environment. My career covers almost all aspects of Windows programming starting from VB, VC++, MFC, VJ, PB, Win32 API, ODBC, ADO, DAO, COM, SQL (namely MSSQL Server), ASP, HTML and so on ..

At end of 1999 I woke up and started to work with Linux. Because of my experiance with windows and NT kernel programming I quickly became familiar with it. What about you ? ;-)

A sport forms considerable part of my life (specially martial sports) and I also like car driving and horse riding.

My current job is unknown. I'm programming whatever I want or whatever wants my chief and I'm also hostmaster of this site.

Uff, my hands hurt so this should be enough !
