Would like to mention J.Teixeira and V.Gordely.
I was invited at the LLB by Jean Rossat-Mignod, with whom I had to
discuss so many things during my staying at Saclay... In July-93 he visited
my home in Chernogolovka. Nobody could imagine that the conference in
San-Diego in August-93 would be his last... That's too bad that he died...

The lectures have been oriented at the undergraduate level of listerners.
That was not a kind of social programming which practically filled a niche
of business-oriented informational technologies. Time to time programmers
can employ some classical and contemporary computing methods and algorithms
in that social programming, but prefer instead to get rid of them, because
these methods are not of their daily needs. From the opposite side, those
people, who are very familiar with the "scientific" part, often feel
themselves uncomfortable with a friendly presentation of their results.
The purpose of the lectures is to demonstrate a full circle of development,
which includes non-trivial computaional methods, starting from a pure idea,
and finishing with a customized product.

-
Perl, I like this interpreter language for its perfect abilities
to make pattern matching, efficiently work with associative arrays, and a
great help when searching at the Internet. I do not think, however, that OO
features of Perl are its best.
-
C, so fundamental, that for me, it is like an iceberg, whose tip I
am only familiar with...
-
C++, I believe, now it is out of any competition, if an IT project
is really huge. The best set of OO features.
-
Visual Basic, a great toy due to Microsoft. I like it, and never
have had problems with it. It's fantastically efficient with fast
applications.
-
SAS, one of the statistical monsters. Until now it is the most
popular, although I am familiar with other tools, more efficient and
friendly...
-
Fortran, old friend, still exploited in scientific projects. Most
likely, due to traditions.
-
Mathematica of Steven Wolfram looks like a monster now, but a
friendly monster. Sometimes I have problems with Mathematica, but they
always appear due to my incompetence.
-
SQL, and its versions and dialects: a perfect monopolist in
database applications.
-
HTML, JavaScript. So, this web page was produced with their help...
