    I always recommend everyone trying to one up their programming skill is to create web server using the HTTP spec. It really teaches a lot about what programming is. There is a document that you have to follow and the expected behaviour, how you handle edge cases, how you optimize some algorithm, etc. Why HTTP and not anything else is jusy because the sheer number of implementation available that you can use as a reference.

Similarly how people still do creative stuff with accounting (eg new ways of building ledgers like crypto) but the basic premise has converged onto a more or less singular agreed-upon convention. Computer Science was fighting that premise at its very core I think with several languages and several programming paradigms. But with the advent of AI the programming paradigms or "code structure" might become meaningless. A computer for example doesn't care if the JS file is minified or beautified. We do.

    First of all, fantastic video. It's amazing how you managed to simplify such a complex topic.
    Second of all - as a software engineer - your corner cutting made my skin crawl. 😅

    You can make a secure web site with about 60 lines of C that is extensible. Did this 28 years ago and was used as part of one the the first internet proxy firewalls.

    Crazy to think we've abstracted all the low level aspects for creating a web server. Just going through all the standards/protocols invented to get this web server going that looks simplistic would take a lot of computer science courses to get a deep understanding of it all.

    I too made a http server, which was just a todo api app. Learnt how http request actually works and parsing them. Fun project, got to learn a lot. Wanted to learn on the security part of this, any insights or references to look into?

    Lovely sample. I used to do all this with a shell script. Same approach, and potentially quite safe.

    Laurence Tratt and @Computerphile, I hope you'll soon make a video explain how an why this naive server is so damn *vulnerable* to many sorts of attacks, particularly BF, DoS and LL attacks.

  • @jslay88
    @jslay88 2 หลายเดือนก่อน +1

    While its nice to see this broken down for people, I also want to stress how dangerous this is without proper security and exploit handling. It is almost always better to implement some well known http server library if you need this functionality.
    It's not just handling files to have basic security here. There are all sorts of RCE via injection you have to be concerned with, etc, depending on which language you implement this in.
    However, this is a great exercise for learning this!

    Would you say there is a use case for this in Internet of Things projects? I've heard of MQTT and other messaging technologies but for a private home network behind a firewall this is pretty low point of entry. I guess I should look into Rust and add that to my Resume too.

    I guess this useful if I wanted to build a server for an embedded system or one of those wireless sensor networks? It should take almost no space and minimum processing, given that we have single user.
