Hope you liked our Revolution of Colors and Titles. Maybe you even have took part in a contest in new status. The last round have set an incredible record: 8000 participants! And I'm glad to tell you that there was no single technical issue during the round time! Consider the 15-minute delay as a part of our evil plan for setting up a new record :)
I'm glad to tell that Codeforces team is able not only to tune colors and formulas, but also to work on new features for you. You may see on contests page that there is a list of authors for each of the rounds! Moreover, in profile of a person there is now an entry called "problemsetting" that allows you to see the list of all contests in whose preparation a person took a part.
Endagorion looks like this.
Unfortunately the paragraph above can't be formally implemented by using all information about rounds we have in our databases. So, all the data was prepared by me almost manually for each of almost 600 rounds we had (including combined rounds and every kind of unusual rounds) on Codeforces, by using information from announcements, editorials, problems autorship in Polygon and some other sources of information (like "Mike, don't you remember, who was an author of Yandex.Algorithm 2011 Finals?"). All this process took two days of my life, when I had to read announcements for all rounds that happened in last five years :) Applauds to Vitaliy kuviman Kudasov who implemented all these features on Codeforces.
(this is how it happened, the image is clickable)
In all data we aggregated, obiously, there are mistakes. If you were accidentally called a problemsetter of unnecessary contest, or if we forgot to mention you as an author, write it down in comments for this post or directly to somebody in Codeforces administration.
And the last piece of news for today. Starting from Codeforces Round #326 I'm no longer a coordinator of Codeforces. I'm transferring this honorable duty to the next person, who is... well, you will eventually know him.
It was a great year when I worked on a super-cool community of a competitive programming and when I met lots of interesting people. See you in the ranking table :)
