Wordles

Wordle got super popular and was then sold to the NYT. There have been a ton of interesting variations on the core mechanics:

  • Wordle for Netscape - Wordle, but works in Netscape 1.0
  • WorDOS - Wordle, but for DOS
  • Worldle - Guess the country, once per day, based on outline
  • Globle - Guess the country, once per day, with warmer/colder hints
  • Passwordle - Guess the SHA-256 password hash (parody)
  • DuoMoji - Emoji matching, once per day
  • DNDle - Guess the D&D monster based on core stats
  • Mathler - Guess the math equation (with a known target)
  • Nerdle - Guess the math equation (including the equals)
  • Mumberle - Guess the math equation (including the equals)
  • Summle - Guess the (very simple) math equation
  • Quordle - Guess four words at once
  • Octordle - Guess eight words at once
  • Semantle - Guess the semantically-similar word
  • Lewdle - Guess the offensive word

Neat little game where you have to place world events on a timeline, along with a Wikipedia card for each one, telling you more. Very addicting

Modular CPU

I love this project - implemented a CPU using euro-rack synthesizer modules. Also introduced me to VCV Rack whish seems super cool itself.

I love the story of The Griddler, a character in the MacDonald's advertising world, but with very little evidence they ever existed.

A great little visualization of how many programming jobs now allow remote, according to listings on Hacker News

555 Timer IC

A very cool home project - you can build a working 555 timer chip out of individual transistors. It's one thing to know that ICs are made of transistors, it's another thing to assemble it by hand and then have it be usable. The very first PCB I made in school used a 555, so this is very cool.

Streaming

I just love this story - The first streamer was a 12 year old on public access TV in 1993

Black Mesa is a re-write of the original Half-Life game, on a modern engine with updated graphics, puzzles and game play. It's a fan-made conversion, that took years, but it's really good.

If you read and enjoyed Bad Blood, the Theranos book, then you will probably want to listen to the "Final Chapter" podcast that talks about what's happened between then and now. The trial is just kicking off and the podcast is tracking that as it happens too.

Can you fit a whole game into a QR code? Some Windows assembly goodness in this video.
