Britney Spears - Born To Make You Happy

I'm sitting here alone within up in my room
I'm thinking up of about the times that we've been through
Oh, my love

I'm looking on at a picture in my hand
Trying to my best to understand
I really wanna know what we did wrong

Zig in 30 minutes

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

Some git recipes, tips and how-tos.

If you want to list all the files currently being tracked under the branch master, you could use this command:

git ls-tree -r master --name-only
If you want a list of files that ever existed (i.e. including deleted files):
git log --pretty=format: --name-only --diff-filter=A | sort - | sed '/^$/d'
