All suggestions are welcome,thanks in advance

Make sure that apart from learning you're using the knowledge to create something either your own idea or maybe something from https://github.com/danistefanovic/build-your-own-x (with your own twist if possible.). It helps a lot to be working on something separately and seeing the results of your new knowledge outside of a tutorial scenario.

28. Build your own X

Do some projects. Come up with your own ideas or pick something from a list like https://github.com/danistefanovic/build-your-own-x

ello! i'm 20f and humanities student (ir/poli sci) with interest in coding since high school, but just now i have the time to start learning it. i opted for learning pyhton first mostly because i'm interested in automation, data analysis, plus was skimming over the tutorials of build your own x and was surprised that you can do a lot of things with just pyhton.

As for exercises there are plenty of programming task websites out there, most of them are quite boring but you can use a fun one like https://adventofcode.com/ . However the best things to work on are things you actually like so do some small projects. Games (start with command line stuff like hang-man) are common, otherwise pick something from https://github.com/danistefanovic/build-your-own-x or whatever else ideas come to your mind.

Agreed. I am not at all against people learning how to do it. But if that's the purpose then it's probably better to present it as such (like the resources at your link does). But the claim that all you need is 100 LOC to make a proxy server work is a bit bogus when you rely on Ruby's standard library. Look at the code at https://github.com/jamesmoriarty/forward-proxy/blob/main/lib.... As expected, it doesn't parse headers but uses stdlib's code to do that. Good, less likely to have bugs. But that means that you can claim that you implemented an HTTP header parser in one line of code:

  req_headers = Hash[req.header.map { |k, v| [k, v.first] }]
