I'm not sure how you draw the conclusion that there is no covered app store. Are you sure https://github.com/c3d/db48x/tree/dev/library is not covered, for example? More importantl…

No, I am not ignoring the GPLv3. This is not a license, but a legal notice that residents of these states, by applying the GPL and freely running software that may violate local la…

This is a valid point, and I was aware of it, though the wording was not clear enough. So I clarified in a recent commit. I also added Brazil and New. https://github.com/c3d/db48x/…

Exactly

DB48x certainly has a GitHub site with freely downloadable pieces of software that can run on the calculator. For instance here: https://github.com/c3d/db48x/tree/stable/library So…

DB48x author here. To be fair, the definitions of "operating system", "application" or "user" are so vague that I decided to 1. Not take any risk 2. Take a stand The point is more …

A video explaining the philosophy and technology behind the project. https://www.youtube.com/watch?v=jNOA39HnkcM

Sorry about that ;-)

It's a tribute to Hewlett and Packard, but taking the first names, and with the individuals reversed for balance. I do not believe there is any possible infringement on a clearly n…

In theory yes. In practice, the TI 83/84 are probably not beefy enough, and the NumWorks has a keyboard that makes the endeavour really complicated.

There are three floating-point representations: - A variable-precision decimal floating point that uses base-1000 internally with 10 bits for 1000 values instead of 1024, so reduce…

This works with Firefox 132.0, tested on Fedora 41 right now.

This is done on that page, though on some browsers it requires an explicit page reload. This works with Mozilla 132.0, just tested on Fedora 41.

SharedArrayBuffer is necessary to run multiple threads with EmScripten.

Could you open an issue on the project's web site about the trouble you had installing? ( http://github.com/c3d/db48x ). Thanks! Also, were you aware of this tutorial: https://www.…

There is a free iPhone version as well (called DB40X). Maybe some day give it a try?

A physicist working on the project used this to compute the space contraction for the https://en.wikipedia.org/wiki/Oh-My-God_particle , which presumably traveled at 0.999999999999…

Let's see your Python answers to the following examples: 1. What happens if I rotate binary pattern 1001 right by 3 positions on a 18-bit PDP-9? RPL code: 18 STWS 2#1001 3 RRC Resu…

> Where's the apostrophe (equiv. to quote in lisp)? That should be an easily accessible key not buried in a menu. The apostrophe is on the XEQ key of the DM42, or "F". But in RPL, …

The current state is "on backburner by lack of time". Projects like https://grenouillebouillie.wordpress.com/2022/03/07/a-theory... and https://github.com/c3d/DB48X-on-DM42/tree/st…

The really ugly stuff is here: https://github.com/c3d/xl/blob/master/src/llvm-crap.cpp

I realized I forgot to share my most memorable piece of code ever: llvm-crap (Compatibility Restoration Adaptive Protocol) https://github.com/c3d/xl/blob/master/src/llvm-crap.h

Check out Pure. https://agraef.github.io/pure-lang/ This was what convinced me to switch to LLVM. I now regret that decision, but at the time, it sounded like a lot of fun.
