Hey, yo! It's been 4 lectures and 4 seminars i have visited this year. Course is named "Algorithm's and data search". Even though I understand not all material while listening this course, it is very interesting.
Yestarday I have listened Binary Search. I didn't thought that there will be so many problems to code that (yep, mr Peter Mitrichev :)).
During the course little by little I starting understand that to code hard tasks you need to
1) have a good mood :)
2) theoretically prove your solve
3) test your solve very hard ;)
4) don't forget about compiler differences
5) shit, again test
Theoretical prove is sociated with some invariant that must be compiled in your mind.

Perl magic
Since i am perl-intern, perl is my second language :)
Some of it is very strange!
For example, pattern /^\w+(\d+)\w$/ match one string blabla01d and doesn't match blabla10d. I know, that \w can match digits also, so I made /^\w+?(\d+)\w$/, so it worked on MY machine. But on other computers first pattern aslo works fine.
So I DON'T KNOW WHAT IS HAPPANING!
Kill me by wall...(c)

Yestarday i found myself that is a good site to practice.
There are a lot of tasks with different complexity.
It's time to make better my skill for resolving problems.
Good luck, all genius ;)

Stuxnet
Ok,there are bad news to Iran atomic station.
Stuxnet virus appears to be a miracle of hacker's art. I read that this is the kind of national bug. Big job to make a sabotage.

Yet another problem
I wouldn't say it is a algorihmic problem.
It is a language problem. For now it is a PERL with MySQL database.
Linux.
Yandex again asks not simple questions...
