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)

kdrnic's Caves of Qud beginner notes

The guide below I wrote mostly for myself as a "notebook" of info I found, but then slightly expanded it with stuff that may be useful to others.

As of finishing writing, I have 16 hours of CoQ playtime and have a level 20 character, definitelly still a beginner as well, perhaps a slightly seasoned beginner.

My previous roguelike experience included beating DCSS with a minotaur berserker and playing a good amount of POWDER on my celphone.

Justification

The game is a tad opaque. As this Qud denizen explains (I don't agree with his overall opinion):

No, your cryptocurrency cannot work

Whenever the topic of Bitcoin's energy usage comes up, there's always a flood of hastily-constructed comments by people claiming that their favourite cryptocurrency isn't like Bitcoin, that their favourite cryptocurrency is energy-efficient and scalable and whatnot.

They're wrong, and are quite possibly trying to scam you. Let's look at why.

What is a cryptocurrency anyway?

There are plenty of intricate and complex articles trying to convince you that cryptocurrencies are the future. They usually heavily use jargon and vague terms, make vague promises, and generally give you a sense that there must be something there, but you always come away from them more confused than you were before.

Visual Studio Sucks

Evidence to back my sincere belief that Visual Studio is the worst piece of software available.

1. It's extremely slow.

   2. It's so bad it now displays this message in the text window before the actual text:
2. When in debugging mode, the method details dialog that appears when you hover over the method name doesn't work.
3. The performance profiler is, ironically, extremely slow.
4. You have to exit VS to install or update extensions
