Tomorrow I am going to stream Codeforces Round #659 and plan to start the stream shortly after the round ends on my twitch channel. I would try to explain my thoughts during the contest and will answer questions from chat. You can ask any questions, not necessarily ones about this contest.
I also plan to record topcoder SRM #788, I am not yet sure if I'll just put it on youtube with no commentaries or stream it over week end (or maybe we can try to watch both tomorrow on 2x speed, we'll see)
UPD: stream started
UPD2: finished with SRM, on to codeforces round
