Where can I find a list of IT conferences and lectures in recent years?

Question

Habr

Hello.
Often I see announcements on Habré that a conference or an open lecture is planned somewhere.
There are no opportunities to go, the main reason is laziness. And I would like to see the speeches of the speakers.
I like the video lectures on IT made by the Yandex and MailRu teams. But there are many more conferences. However, when I remember that some of them were discussed a couple of weeks ago, the ends can no longer be found.
Maybe somewhere in the vastness of RuNet there is a list of IT conferences and lectures in recent years? (with links to video recordings of speakers' speeches.)
Thank you!
