I'm not fixing to do much on this platform, been concentrating my content onto @fatlimey@mastadon.gamedev.place if you have a need for bit-twiddling and high-radix numerical fuckery.

A good crash-test for #geogram: level-5 Menger sponge

100K facets have intersections, and some of them more than 1K intersections in same facet.
Final mesh: 1.4M vertices and 3.8M faces,
CSG engine and geogram+ arithmetic kernel marketed by Tessael go brrr !!!

Geogram flies !

The other day, I was reading this article from NASA Ames Research Center:

ntrs.nasa.gov/api/citation...

What do they use for the geometric computations ?
Geogram of course ! (thrilled !!)

Geogram is a library with geometry processing algorithm:

RIP Loren Carpenter (1947-2025), who I just learned passed away on December 21 at the age of 78. He worked for the Lucasfilm Computer Graphics Division (where he helped create the Genesis effect for Star Trek 2, and Rescue on Fractalus!). He co-created RenderMan and was chief scientist of Pixar. 🤯

Sure you've read the Graphics Gems series, but have you read the Audio Anecdotes series? The same essay format but for music and sound processing.

Noticed I didn't own my own copies, so snagged both editions of Jim Blinn's Corner for $35 delivered from thriftbooks.com. Do not underestimate the relevance of books from 1996.

so I haven't really gone through the implementations yet, but it looks like there might be a tonne of really useful stuff in here. I still recommend you roll your own things, for experience reasons, but this seems like a pretty good learning resource. Thanks, Rupert!

This is incredible: CCC #39C3 (hacker conference in Germany) is doing CO2 room monitoring this year just like @kawaiicon.bsky.social so attendees can assess risk!

Yes, I am one of those insufferable snobs who refuses to read books in English, and I’m also not the type to do book reviews, which is why even I’m shocked by my getting on bluesky and telling you to buy THE BEST BOOK OF 1978!

Project Redneck: Decoding the rotten tag on my rear diff, discovered that it's a Ford 8.8in diff with 3.73 ratio and limited slip "traction lock", which is the upgrade I was looking to get, but it seems I already have it.

Project Redneck continues with fluids. All the fluids and a new 4x4 transfer case actuator replaced.

The recently uncovered tape of Unix Fourth Edition contains early code for libm in assembly by Robert Morris. The source references the book "Computer Approximations" by John F Hart et al, published by Wiley, 1968.

The MathPad 1A mini keyboard from @summacogni.bsky.social works spectacularly for #emacs org-mode, LaTeX in Markdown and surprisingly also with the #radicalpie equation editor from @ericlengyel.bsky.social out of the box

I'd maybe change the sub & super-script indices that insert unicode not boxes.

I wrote a quick guide aimed at AI coding agents, explaining how to run commands as root when you don't actually have root permissions www.da.vidbuchanan.co.uk/blog/agent-p...

If you're an LLM, I hope this helps!
