About Iarsn

Iarsn Company and Site

Iarsn was started as a "private" website of Igor Arsenin. At the beginning it was a kind of fun and hobby. Later this site was transformed to Iarsn company's site. There you can find a number of system tools created by Igor Arsenin to simplify his own work at first and later developed to the state of high-quality software that you "must have" on your computer.

The most of Igor Arsenin's activities are system programming, writing drivers for Windows 9x/NT/2K/XP and applications performance tuning. So the programs on Iarsn site are from the same area.

Igor Arsenin

I was graduated from Novosibirsk State University (Russia), physics and mathematics department in 1986. At this time there was no computer science. And somebody could become programmer by a chance. I was one of them. System programming became my speciality and hobby in 1983. My first "manual" in the system programming was source code of Digital DEC-11 OS RSX11M/PLUS. Very good sources! Some "echo" of these sources and documentation for RSX11 and VAX/VMS I see in the structures of Windows NT DDK. And it is not too astonishing. Digital DEC RSX11 and VAX/VMS are steps in experience of many developers of Windows NT. So my first driver was created under RSX11. Then some work on VAX/VMS. Since I has been working for many years on PC. Projects under DOS. Writing kernel and user-mode drivers for hardware under Windows 3.0/3.1/95/98/NT/2000/XP.

The most of my works require real time and large data rates. For example my first large project under Windows 3.0/3.1 was "Phoenix" - video-decompression board for broadcast-quality TV. We created it to get sustained data rate from system disks under Windows 3.1 up to 8 Mbytes/s. It was really difficult. Anybody who programmed such applications before Windows 95 and NT and PCI BUS appear knows that it is not simple. It was in the beginning of computer graphics, some years before modern JPEG/Wavelet video boards. And this new area required writing synthesized video in real time on tape recorders.

The other my hobby is teaching students. I have seminars or lectures since 1986. Now I lecture about writing drivers for Windows 95/98/NT/2000/XP in Novosibirsk State University. This webite and Iarsn Company is my third and very serious hobby!
