I'd recommend using ghcup to install Haskell nowadays. (https://www.haskell.org/ghcup/) It makes it easy to install and switch versions of the compiler, language server, and build tools.
Haskell's ecosystem went such a long way in, I d say,last 5 years? Or maybe it's just me who became more proficient at following instructions? I distinctly remember not being able to setup my working environment for Haskell sometime before 2018 and then I tried it again couple of months ago, and all well smoothly
I've always liked Twilio. I stopped using it about a year ago because there was no longer a need for me to continue using it, and they have this "feature" where you can suspend your account, which means that it will release all numbers and disable billing, so that you can reactivate it later without having to worry that you get billed accidentally.
I wanted to do the same with AWS this week, since I'm always getting 0€ invoices, and I'm worried that some day something will happen without me doing anything and I'll get billed for it. Apparently it isn't even possible to set a spending limit of let's say 5€ as a warning mechanism.
