Yesterday I was looking up a couple of things, and I landed on Thomas Ballinger's website. Specifically the article about Garbage Collection. I only actual understood the point of the article after watching Guy Steel's talk "Growing a Language (on YouTube)" or read it here (PDF via archive.org).

I highly recommend it.

Here are a couple more things that are interesting: Dal Segno, Crafting Interpreters (by Robert Nystrom)

sudo systemd-resolve --flush-caches

Discovered NixOS/NixPkgs and I've been running it (mostly) happily since. It feels more empowering to manage my machines and configurations instead of the usual shell scripts, (bare) dotfile repositories, Ansible & Saltstack. Track my home-manager's configuration here on GitHub

(I would still use Ansible or Saltstack for [fleets of] machines that aren't tailored to my specific needs.)

Also discovered Guix but after some reading I decided to skip it in favor of Nix for now.
