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!

yes , you just listen to the scrolling event and request additional data

@@prashantsihag3489 also websockets is two way connection if u only want to push data and not take any dynamic data from client u should use server side events that's better coz web sockets add a bit more overhead and also can make u prone to attacks as u listen to client and have vulnerabilities

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 Год назад

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

@the_god_killah 11 месяцев назад

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.

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

@mariuszdziem8203 3 года назад

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 года назад

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

You are trying to teach this open-source subject (web-design related topics) on the totally closed platform (MAC machines and OS). Is this a joke? If not, then call your video "dedicated to MAC lovers only...not for the vast open source community". I cannot believe a software engineer would use a fashion-designer's tool... unless he works for Apple.
