Since i have tired to see my ubuntu clocks asynced, i have decided to put following code snippet to /etc/rc.local file:
for SERVER in ntp1 ntp2 ntp3 ntp4 ntp21; do
echo "Trying ${SERVER}.vniiftri.ru to connect"
if ntpdate ${SERVER}.vniiftri.ru; then
break
fi
done
Vniiftri is Russian center of time control.
I assume that there is nothing bad in connecting to ntp*.vniiftri.ru every moment my laptop starts.

Python is nearby!
Recently I've decided, that knowledge of Python will be a good addition to Perl-programmer.
Althoug, it is beautiful (maybe just beacuase it's new to me), it has some big disadvantages.
One of them is that it is very slow! Yestarday night and tomorrow I had been fighting with problem on codechef:
http://www.codechef.com/problems/INTEST
http://www.codechef.com/problems/INTEST
Nothing helped me to pass the test. The failure is in the way how Python reads from stdin. It's very slow. Neither raw_input(2.7.2), nor input(3.2.1) passed input test limit. Moreover, I tried os.read() function and again not good news :( . I also found direct method reading from stdin: sys.stdin.readlines(), but it was not helpful.
What can I say? Maybe Python < 2.7.2 really can handle it:
But now in codechef there is Python interpreters greater, then 2.7.1
One failure is unable spot my mood. But it is not very cozy to know, that upgrading PYTH on your large data-set systems can cause increasing execution of functionality, written on python .
