Answered to a sibling comment. NLnet and HORIZON.

NLnet is just amazing and can keep you going if you are a student or have some extra sources of income

HORIZON is a huge grant but fairly hard to obtain. Generally related to reasearch grants in academia

First we got a grant from the NLnet[1], which I highly recommend as a first step of any project. Single best thing I could have done. That wasn't enough money for me to quit my job. Also I didn't have any _evidence_ that IronCalc was a good idea or that there was a market for it. Then evidence started pouring and I kept working. I started talking to different folks, lots of people many of those were contacts through the NLnet. Then the folks from NextGraph[2] approached us and asked, "Hey do you want to be part of this consortium [3]?". Eventually we got a HORIZON grant after a lot of sweat and paperwork, but NextGraph took the brunt of it.

As you see there is a huge component of sheer luck

Well, I just jumped full time on IronCalc[1] a fully open source, light and fast spreadsheet engine designed and build from the ground up.

I have been working on it as side project for over two years and now, with funding from the EU for the next 2.5 years, I hope I can make of it a real product for everyone to use that can compete with the likes of Excel and Googl;e Sheets.

I can oly say, I am overly, off the Moon excited

Elliptic Tales, but maybe it is because I read it first

I'm sure it's a great book :).

I find good popular books on higher mathematics difficult to come by. A nice exception is the trilogy written by Avner Ash and Robert Groß:

Elliptic Tales, Fearless Symmetry and Summing it up (in my order of preference)

Thanks for the mention! That's indeed the plan

Hi! Congratulations to you and Yousef. And I am lucky enough to be in a position from learning from both of you.

Anyone think what they might about La Suite, but blocknote is a solid product!

Aaron Swartz has a nice blog post about it[1].

It's been discussed several times on HN[2]. I had periods I go through without news. It's been harder to do that lately.

That is exactly the kind of thing I was looking for. Thanks you!

Yes, those are fascinating technologies. But way too big to be running in a small app in the browser.

I submitted that link. In all fairness the link in this post is more accurate. I'm glad to see people are interested. Let's see where all this goes.

Eli Bendersky's post are always insightful and interesting.

I really would like to see a small language that compiles to wasm in the browser.

Of course you can use things like Lua that has it's own vm also in wasm. Or Rhai with it's own interpreter. But I am looking for a language that compiles to wasm in less than 1Mb of wasm

Sorry! It was too beautiful not to share it. But I'm sure you can do a show HN once you think is ready.

You’re the inspiration, my friend.

Sure :)

Those happen. Best wishes for 2026

Some heartfelt comments on that thread. Also interesting his first blog post:

Great book. Previous discussion: https://news.ycombinator.com/item?id=35492307

Physics, of course. Well, at least that is what I was doing before. If not that teaching. Math, physics, programming. I could teach any of that I guess

Damn... So good. Thank you!

(Kind of embarrassing TBH)

I assume they meant 1.e+00

That is what Schubfach does

No, not really.

So if I use:

    #include "zmij.h"
    #include <stdio.h>

    int main() {
        char buf[zmij::buffer_size];
        zmij::dtoa(1.0, buf);
        puts(buf);
    }

I get `g++ zmij.cc test.c -o test && ./test` => `0.000000000000001e+15`

Quick question, if you are still around :).

I have been doing some tests. Is it correct to assume that it converts 1.0 to "0.000000000000001e+15".

Is there a test suite it is passing?

Oh wow, I would love to see that if you can share it :)

Yes, Dani the designer involved in the project, keeps saying that. There are two things that stops me from doing that:

* It would make the landing page a bit heavier * I would need to synchronize deployments somehow

But I guess I should do that sooner rather than later.

Thanks!

This blows my mind TBH. I used to say a few years back that Ryu is my favorite modern algorithm but it felt so complicated. Your C implentation almost feels... simple!

Congratulations, can't wait to have some time to study this further
