This is amazing!

HackDays - Hackathon Digital Workspace Les 2, 3 et 4 Juin 2025 - Travaillons ensemble à développer des outils souverains & open source

IronCalc goes to Paris! We will be participating in the Hackdays with La Suite Numerique:

Any place is good for a couple of quick fixes

November!
"A plea for lean software" was written in 1995, today is even more relevant.

Dear friends, I'm rejoining Redis. It's a long story, so it deserved a blog post to explain all the details: antirez.com/news/144

GitHub - ironcalc/TironCalc Contribute to ironcalc/TironCalc development by creating an account on GitHub.

Amazed to see this! Interesting in collaborating? Also did you see Tironcalc:

Folks building with IronCalc!

That's the spirit!

This means that (from a cold start) 583k. Once uncompressed it is 2.8MB and the whole thing loaded in 269ms. Of course you only download all this once, from there on it is cached by your browser.

We used the fantastic regex-lite crate from @burntsushi.net and reduced the wasm build in 1 Mb! The total js+wasm+other downloaded in the IronCalc app is 583kB.
Long live lean software!

One of the most complicated theorems in all mathematics is the classification of finite simple groups. Turns out there are infinite series of finite simple groups. And a set of 26 "sporadic" groups. Of course, the monster is the 26th, by far the wildest of them all.

But there are second kind groups that have only a finite amount of elements. Like the symmetries of a square. We can rotate the square 90, 180, 270 or 360 degrees.

A Group is a kind of mathematical construct that represent the symmetries of an object. There are continuous groups, like the group of rotations that are a symmetries of a football ball. In mathematics we call that group SO(3, R) and lies at the foundations of mechanics, both classical and quantum
