Күн бұрын

A gentle introduction to the web-socket protocol, how it works, it's intended usage and a number of examples where it can be used with Python and it's popular web frameworks - topped off with a rapid demonstration of the speed and ease of which it can be implemented with Python.

This is still amazing, even in 2022. There is now so much wide spread support for websockets, thinking apollo client in particular, that it's nice to get back to fundamentals. Starting with the OSI layer and working our way all the way up the stack to socket IO. Great job!

what does it mean when we say that UDP doesnt care about losing data while streaming videos? Shouldn't we get the whole video back? I never noticed a video that isnt well sent and dont understand that implementation example.

@plugthesnippet6583 Жыл бұрын

My guess is when a video is playing on lower quality, there was data loss

@the_god_killah Жыл бұрын

I think it’s when a video is buffering or live stream is lagging for a couple second it means u lost data and then it goes right back to good quality. So udp is faster.

@harshjain4989 12 күн бұрын

Let's say you are watching video at 60fps. Each second you get 60 frames. However if one of the frames is lost or corrupted then you would not even notice as our eyes can't tell if a single frame is skipped or not. This is what is meant by it doesn't care about losing data.

But how web sockets work? How the browser do this?

@mariuszdziem8203 3 жыл бұрын

IT just works! :) If you want to know more, download open source Chromium code, and have a look in milions lines of code ;) You need a lot of patience to figure it out :) Browser knows the protocol, and use that protocol, to behave in proper steps. It connects to normal IP number, and knows that protocol deals with websockets. Thats it.

@tikz.-3738 3 жыл бұрын

U send request to server the server recives it and has a code defined to reply to it when reply is received on front end u can render it as u define on client js, now browser s role is just helping u navigate to site give basic css and show html and run client js rest all is ur code u don't need to look at broweser code and it isn't required to know how websockets work
