Hey there! Since new year is coming, I want to start little summing-up of the ending one (of course we still talk about hacks :)).

I wrote another short script, which purpose was to summarize all hacks in the 2014. I wanted to upload it after two last rounds, but mostly because of little differences (especially between first and second place), I did it before last rounds. Maybe the next rounds will be more exciting because of it.

Below there is a list of 50 best hackers in this year (so far), the full list can be found here.

Update: After last round, the ranking was updated.

The last round was decisive: mosiomohsen made 5 successful hacks and 1 unsuccessful and with 450 points, he managed to surpass anta. Congratulations!

Extremely awesome work, kostka. Hacking submissions in a live contest in itself is an art — which a lot of us (Like me, only 1 successful hack!) need to work on to improve. :)

Finally someone found something regarding competitive programming where tourist is not at the top.
Makes one question the authenticity of the post though. :P

    But he's one of the most accurate, though. Among top hackers he has the lowest mist percent :)

One more idea, you may also build a rank by "points per round". Take all guys with, let's say, 5 or more contests during last year, and sort them by challenge points/number of rounds. Not everybody participate in every single contest :) And also most of div1 guys don't take part in div2 only rounds.
