I accidentally created a photo book company to answer the question of whether students should study computer science re AI writing code rgbloom.com/blog/should-i-st…

Fascinating to see all the many commits to Bun's Zig to Rust port github.com/oven-sh/bun/commi… ... over 50 commits in the last hour! @bunjavascript

Introduced 25 more A-level students to @bunjavascript this week. The punt I took on Bun 2 years ago has really paid off. Such a great way to learn JavaScript (and TypeScript), and it keeps on getting better!

I made a super simple spinner that randomises the order of items - perfect for teachers to eg randomise the order of students presenting to the class: mathsuniverse.com/spinner

Pathfinding algorithms (Dijkstra and A*) visualised on real maps of Cambridge. Useful for A-level computer science teachers/students: mathsuniverse.com/pathfindin… I had lots of fun finding out how to use OpenStreeMap (OSM) data and the OverPass API with this one.

Day 8 of #AdventOfCode using JavaScript via @bunjavascript . A pretty good solve, but 5mins wasted misunderstanding an example at the end. Video at youtu.be/fvhXpLchv_Q #AdventOfCode2024

Day 5 #AdventOfCode using JavaScript via @bunjavascript . Not too many silly/time-wasting mistakes on this one. Video at youtube.com/watch?v=5WKaNGOl… #adventofcode2024

Day 3 of Advent of Code using JavaScript via @bunjavascript . This one was all about regex skills. #adventofcode #adventofcode2024 Video at youtube.com/watch?v=VqrHAKp_…

Computer science teachers: I've made some videos showing how to use my free Little Man Computer simulator, which uses binary and is pretty slick: m.youtube.com/playlist?list=…

🚀Just launched an updated version of mathsuniverse.com/infinity . The UI has been simplified, dark mode is improved and there's a new menu. Try it out and let me know if any problems.

I've made some changes to mathsuniverse.com/forms which should make it more robust to connection issues, and so teachers see student answers even quicker. I continue to use this invaluable AfL tool almost every lesson. Try it out if you haven't already. It's free.

I've made a change to mathsuniverse.com/infinity which should fix a bug where sometimes PDFs wouldn't load.

Are you a computer science teacher keen on teaching JavaScript (we teach @bunjavascript on the CLI/server) to high achieving sixth formers in Cambridge (UK)? Get in touch, we'll be expanding the department soon!

I'm seeing several hundred visits a day to mathsuniverse.com/pixel-art at the moment, which is more than I'd expect. If you're using it in your lessons, can you let me know how you're using it?
