The Lagrange polynomials form the normal basis of most Finite Elements Method (FEM) software. There are other polynomials which are used as well, but these are the workhorse of most solvers.

I actually use fossil all the time for my projects. It just makes more sense to me in the way it works and the ease of use. And you can self host your repos with ease, for example [1]

Congratulations! But I can’t find the source link, nor the license …

I agree. Here is my little site, which I try to keep minimal, fun and fast: https://hdrz.cc

OK I watched the whole thing. Highly recommended! It is about the rivalry between Sinclair and acorn, where the head of acorn once worked for Clive sinclair. It is about the time before ARM.

Reminds me of the past, as my first computer was sinclair spectrum. Fun times!

Just watched the first minutes of the film. Looks like it’s about Sinclair, which is of-course pretty good as well. When I have time will watch the whole thing, maybe ARM will come up as well.

Try doublecmd[1], much better then tc, open source, updated frequently, works on all platforms. Oh and written in object pascal, which I like a lot!

Oh man. 9 years… just pick something, one thing. Just one new (or old) technology that interests you, and code something with it. That’s all. After that, code the next thing. That’s all it takes. For reference, I still code with Object Pascal (because I like it), don’t care about newer languages. Recently got interested in lisp, picked janet[1], and coded something with it. Just do it (R) [1]: https://janet-lang.org

The first commenter on the article page states that his favorite is pdp-11 assembly. In the 90s at uni I learned to write assembly on pdp-11 emulator running on a pc. It truly was a nice experience.

Sure there is: https://xdrip.readthedocs.io/en/latest/ This is for android, there other projects based on this code for iOS as well.

C with dynamic arrays and classes? Object pascal says hello…

This. Just use the most immediate thing available. For me its: * Apple Notes * Apple Reminders That’s it. Gets the job done.
