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

"Animated Bokeh" has been on my whiteboard for a long time, and this is the result.

I thought it would just be for cheesy novelty effects, but it also does lightfield manipulation that was cooler than I expected.

What an excellent job description. If I didn't already work there I'd want to work there.

Successful candidates display a sense of curiosity and adventure, a desire to work on interesting projects, and exceptional musical taste. Pacific Light & Hologram is a wondrous company doing several impossible things simultaneously under the cover of being a vegan chorizo factory. The benefits are great, the work is fun, and the other employees often shower. A cover letter is REQUIRED which specifically addresses the content of this ad. Submissions without cover letter, submissions with incompatible qualifications, and random AI submissions will be binned with prejudice.

You can test new tech ideas using the Seinfeld Test

Would the product eliminate the plot of an episode? (Google maps, cell phones, paypal, battery packs)

Good tech.

Would the product inspire new Seinfeld plots? (NFTs, AI chatbots, crypto currency, blindboxes, metaverse land sales)

Bad tech.

The simplex algorithm is super efficient. 80 years of experience says it runs in linear time. Nobody can explain _why_ it is so fast.

We invented a new algorithm analysis framework to find out.

I've worked very hard over many years to develop a complete and correct picture of Grassmann and geometric algebras, often in the face of extreme antagonism. The results of my efforts are now being adopted by prominent scientists and engineers in various fields.

This post shows how to get different constants for the R2 low discrepancy sampling sequence which have the same properties, but are smaller valued, so behave better in floating point at high sample counts.

Tweet by Jatin @jatinkmalik The reason why RAM has become four times more expensive is that a huge amount of RAM that has not yet been produced was purchased with non-existent money to be installed in GPUs that also have not yet been produced, in order to place them in data centers that have not yet been built, powered by infrastructure that may never appear, to satisfy demand that does not actually exist and to obtain profit that is mathematically impossible

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!

a dashboard screen showing current CO₂ levels in ppm (parts per million) for 15 rooms / spaces at the Chaos Computer Club’s 39C3 conference the levels are illustrated with tachometer-style indicators that are colour-coded using standard green (good) -> yellow (medium) -> red (bad) colour scheme correlating with the ppm measured in each room the raw ppm value for each room is also visible in the middle of its respective “tachometer”
