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.
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
- 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!
