And no, I have not tested it because I don’t know how I’m actually supposed to do that.

depends on what you backup and how.

if it’s just “dumb” files (videos, music pictures etc.), just retrieve them from your backups and check if you can open the files.

complex stuff? probably try to rebuild the complex stuff from a backup and check if it works as expected and is in the state you expect it to be in. how to do that really depends on the complex stuff.

i’d guess for most people it’s enough to make sure to backup dumb files and configurations, so they can rebuild their stuff rather than being able to restore a complex system in exactly the same state it was in before bad things happened.

or mypy

good book to learn javascript, should also work as an introduction to programming in general.

if you want to dive deeper into web development. they also have introductory stuff, but cant really vouch for that, only found it after allready working for some time.

I guess some lessons need to be learned through pain.

• Commiting regulary.
• Following the branch rules.
• writing tests.
• writing tests, that test the desired not the current behaviour
• refactoring your code.
• not refactoring code, you don’t understand nor have tests for.
• actually reading code before merging a pr.
• not pulling in 23 unmantained libraries to solve a simple problem.
• keeping your dependencies up to date.
• that dirty hack will make your life harder.

Yes, all those hurt. They sometimes still do, most of us are not machines that turn caffeine into code and we are never as clever as we think we are.

Might be a good way for someone who is familiar with a higher level language.

Than there is of course “The C Programming Language” by Ritchie and Kernighan and “advanced programming in the unix enviroment” by stevens and rago.

So, i’d guess just get your feet wet with small stuff. Find out how to take arguments from the command line, or read a file, maybe programm a simple guess the number game. After you are more familiar with the syntax and so on you could look into using your c code in a higher level language. For python you’d have to look into ctypes for that.
