IBM patented Euler's 200 year old math technique by repackaging a well-established mathematical concept of generalized continued fractions with new, flashy branding like "CoFrNets" and "ladders."
They implement this in PyTorch, using the reciprocal as a nonlinearity, and achieve mediocre results (61% accuracy on a simple dataset).

🔣 Mathematical proof debunks the idea that the universe is a computer simulation
｢ They used powerful mathematical theorems—including Gödel's incompleteness theorem—to prove that a complete and consistent description of everything requires what they call "non-algorithmic understanding." ｣

Wow, that's a lot of pennies.
@lowqualityfacts Making change has always been difficult for me. I’d hand over a dollar and ask for 8.818 ounces of pennies. But that’s only want to give me 0.8 ounces of quarters. That screws me out of a whole 8.018 ounces of metal.

@jenskutilek’s wonderful page on Reviving the IBM Selectric Composer Fonts strikes me as the perfect overlap of tech/type/math/research interests that also overlap on Mastodon: https://www.kutilek.de/selectric/

One of our members, indiekid, has a maths/game balancing puzzle he'd like help with. Any ideas on this? Boosts very appreciated!

Best effort embedding of an octagonal tiling in 𝑅³ of a surface of genus 111. Each octagon has vertex valences [3,4,3,3,3,4,4,4].

Given the drama surrounding the arXiv for its dependence on Google and its recent ban on review articles in computer science, I have a question:
Do we still need the arXiv?
Wouldn't a federated network of institutional repositories be a much better option?
