Contests that I participate in, as well as a few tools.

See clist.by for an extensive list. Most of the contests which I do are a subset of those shown in "Programming Contests.png". A link to my google calendar for contests is available here. See the other page for olympiads such as USACO.

Make sure to upsolve after the contest ends! I particularly enjoy problems from AtCoder and CSAcademy. :)
