Courtesy of Erling there is a new problemset - regex - which contains levels from his project Regex Golf. I suggest you check your regexes on that site before submitting it here, so you know how good they are in advance. First 6 problems are worth 5 points and the rest (for now) is worth 10 points. Good luck! 2012-08-21 16:11:08 Rejudge by Piotr Kąkol

All programs in all tasks have been rejudged due to update Python 2.5 into 2.7. 2012-02-08 22:54:22 Language rankings added! by Piotr Kąkol

From now on there are available language rankings which You can check by clicking on language's name on main ranking page. They (and now also the main ranking) are updated every hour. Hope it will increase the rivalry in the less popular languages. 2012-02-01 14:06:19 IRC channel by Piotr Kąkol

Finally language ranking was fixed.

It's sorted by: POINTS->MAX->SOLVED (where POINTS is language's score, MAX is the number of tasks where each language got max points and SOLVED is the number of tasks solved by each language).

Enjoy. :-)

Thanks to Adrian Kosowski there appeared a new ranking. Now score for each task is calculated with formula:

(shortest_length/user's_length)*points_for_task

Tasks from "main" - 10 points each,

tasks from "tutorial" - 5 points each,

tasks from "printing" - 5 or 10 points.

Now You can rival. :-) 2009-12-20 13:00:00 Welcome! by Piotr Kąkol
