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

I made a tiny 100 line library to abstract away pesky WebSocket messages and just invoke remote functions in @bunjavascript and web browsers. Works from server or client. github.com/jakeg/websocket-f…

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.

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?

🚀Launching mathsuniverse.com/lmc - a little man computing (LMC) simulator that uses binary instead of denary. A great resource for teachers and students of computer science to learn assembly, the FDE cycle and 2's complement.

Do let me know how you've got on with this if you've had a chance to try it in your lessons. Suggestions/feedback very much welcome.

I've now used this in all of my computer science lessons this week with wonderous results. I can make a new form in 5-10 seconds and have have students joining it and seeing their answers 20 seconds later.

I create the form then sit at my desk watching their answers roll in. I quickly spot misconceptions and intervene with individual students. Those like @adamboxer1 and @mrbartonmaths will surely love the high participation ratio this enables. All students are answering.
