Quantum mechanics of calculations

The client has a slow device, and you need to do a lot of hard work in the UI-stream.

• How to achieve 60 fps without turning the code into spaghetti?
• How to cancel already started calculations when they need to be repeated with up-to-date data?

You have a server that calculates the response to the request from 1 ms to 10 s.

• How to make sure that long tasks don't block fast tasks, without creating a thread for each request?
• How to cancel already started calculations when the client has disconnected?

Spoiler: stackfull fibers will help us to give each task a processor time by quants up to 16 ms.

In my childhood I had a computer but didn’t have any toys. So I had to invent them myself. So I became a programmer. I used to work in Yandex, Wrike, Saprun, Gazprom. I created a few startups. Including a web framework that was ahead of its time.
