Ok, maybe you have no idea what are we talking about, but this weekend took place the qualification/preliminary round for the CodeGate Hacking Festival. Of course we at Sexy Pandas couldn&#8217;t miss an event like this one, so we had the pleasure of participate and to realize about the high level of the competition.
The contest [...]]]></description>
