А вот кстати, завтра закроется регистрация на математический курс от Jet Brains. За три недели мы там поговорили про многочлены в целом, про разностный многочлен и вычисление разных сумм, про интерполяцию. Сейчас у нас первая неделя комбинаторного (дискретно-вероятностного) блока. И в нем мы дали одну, кажется, довольно трудную задачу. На вчерашний день ее правильно решил только один человек... из 400 зарегистрировавшихся на курсе (ну ладно, кого я обманываю, из 80-ти активно решающих). В конце недели опубликую эту задачу в комбинаторном канале (@olympcomba)...

Lastly, the web previews of t.me links have been given a new look, adding chat backgrounds and design elements from the fully-features Telegram Web client. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. "We're seeing really dramatic moves, and it's all really tied to Ukraine right now, and in a secondary way, in terms of interest rates," Octavio Marenzi, CEO of Opimas, told Yahoo Finance Live on Thursday. "This war in Ukraine is going to give the Fed the ammunition, the cover that it needs, to not raise interest rates too quickly. And I think Jay Powell is a very tepid sort of inflation fighter and he's not going to do as much as he needs to do to get that under control. And this seems like an excuse to kick the can further down the road still and not do too much too soon." False news often spreads via public groups, or chats, with potentially fatal effects.
