easy-peasy with rectangles and arrows. but how to create same thing in rust?

What program do you use to draw these diagrams?

[@interviewpen]

The graphics are drawn in Figma, and we use GoodNotes on an iPad for the laser pointer. Thanks for watching!

When I see "Video Streaming: I immediately think about UDP . Why using HTTP?

[@interviewpen]

That's a common misconception! For live streaming, UDP can be vey helpful, but for normal video streaming, we want to ensure the client is actually receiving each frame of video we send them. For that, we need the reliability guarantees that TCP provides. Thanks!
