#ГеометрияДляВсех #Новости Недавно побывал в гостях в 57-ой школе на кружке у замечательного учителя геометрии Р.К. Гордина (возможно вы знаете его учебники). Рассказывал о разных интересных геометрических конструкциях и одна из разминочных задачек была такой:

That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. Either way, Durov says that he withdrew his resignation but that he was ousted from his company anyway. Subsequently, control of the company was reportedly handed to oligarchs Alisher Usmanov and Igor Sechin, both allegedly close associates of Russian leader Vladimir Putin.
