Hi. I have a few announcements.

Among Us stream on Sunday, 20:00 CEST (just after CF 675 div2). The current team is me, Egor, kostka, tmwilliamlin168, alexwice, xiaowuc1, SecondThread, Reyna, mesanu, the_white_devil, SlavicG, gupta_samarth, lior5654. See you in the chat! https://www.twitch.tv/errichto

I stream programming regularly now: every Tuesday (hard Atcoder upsolving), Thursday (coding interviews) and Saturday (easy Codeforces problems), always starting at 9:00 PST / 18:00 CEST / 21:30 IST. You can import my google calendar. I won't announce these streams in Codeforces anymore, so say goodbye to blogs like "My Coding Streams in Month X". I might do an exception for something unusual or guest episodes. The schedule will always be at the bottom of my Twitch page https://www.twitch.tv/errichto.
(So yeah, Saturday easy stream starts in 15 minutes!)

If you are high-rated and I know you, you can join me for a Tuesday stream and we would solve hard AGC problems together. For example, I might be soon joined my mnbvmar for such pair problem-solving. If anybody's interested too, let me know.

Also: past live streams are available here; I'm preparing Gaussian Elimination lessons for CF EDU; join my Discord server.
