I made it on there with my revival of Real World Haskell :D

Cabal is more than sufficient for my purposes nowadays. I'd recommend reading their Getting Started page:

https://cabal.readthedocs.io/en/3.10/getting-started.html

That gives an overview of the basic functions and for example how to add new dependencies.

For setting up the entire toolchain, I'd also recommend GHCUp's first steps guide:

. means function composition in Haskell. (f .) . (+) is just an obscure way to write \x y -> f (x + y). It's not recommended to use this point-free style in production code, but it is sometimes fun to experiment with for challenges like this.

They are considered volunteers in the Netherlands as long as the compensation is way below market rates. I don't understand why you think this is a problem.

In the Netherlands, volunteers can be paid up to €5.60 per hour and up to €2100 per year (tax-free).

The Netherlands also has mandatory ID.

It's e2e encrypted, so what could they do if they were evil? (honest question)

Not only is it convenient, it also enables parallelism:

"How to Think about Parallel Programming: Not!" - Guy L. Steele Jr. (Strange Loop 2010)

I'm confused. It does go straight to the discourse post when I click it.

You can choose a custom donation and make most of your money go to the EFF. Then the top tier is just like a €24 donation to the EFF and you only really "pay" €10.30 for the actual books.

Een belangrijke overweging van mij is dat de partij groot genoeg is om echt het verschil te maken. Daarom ben ik recent lid geworden van Groenlinks. Ik denk dat Groenlinks-PvdA de enige fractie is die groot genoeg en ook duidelijk pro-europa is.

Or anywhere in the EU. And I don't think the USA is more lenient on piracy. But perhaps they are if a big company is the one doing it.
