I'm renewing my efforts to make mastodon.social/@roytries my primary social media account. I've also updated my blog to point there. While at it I've also blocked ChatGPT via arobots.txt file, I have to keep trying to put morals over convenience, right? :D

Jolt Physics got soft body physics today! There's still a lot of performance optimizations to be done, but you can start playing around with it! github.com/jrouwe/JoltPhysic…

National Lab (LBNL) results support LK-99 as a room-temperature ambient-pressure superconductor.
Simulations published 1 hour ago on arxiv support LK-99 as the holy grail of modern material science and applied physics.
(arxiv.org/abs/2307.16892)
Here's the plain-english explanation:
- The simulations modeled what the original Korean authors proposed was happening to their material - where copper atoms were percolating into a crystal structure and replacing lead atoms, causing the crystal to strain slightly and contract by 0.5%. This unique structure was proposed to allow this amazing property.
- @sineatrix from Lawrence Berkeley National Lab simulated this using heavy-duty compute power from the Department of Energy, and looked to see what would happen to the 'electronic structure' of this material, meaning, what are the available conduction pathways in the material.
- It turns out that there are conduction pathways for electrons that are in just the right conditions and places that would enable them to 'superconduct'. More specifically, they were close to the 'Fermi Surface' which is like the sea-level of electrical energy, as in '0 ft above sea-level.' It's believed currently that the more conduction pathways close to the Fermi surface, the higher the temperature you can superconduct at (An analogy might be how its easier for planes to fly close to the surface of the ocean due to the 'ground effect' that gives them more lift.)
This plot in particular shows the 'bands', or electron pathways, crossing above and below the Fermi surface.
- Lastly, these interesting conduction pathways only form when the copper atom percolates into the less likely location in the crystal lattice, or the 'higher energy' binding site. This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location.
This is insanely bullish for humanity.

The alternate definition of the verb, ‘tweet’, as in, ‘to make a posting on the Twitter online message service’, is in the actual dictionary. No other social media app has anything like it. Imagine disposing of that level of brand recognition because of a mid-life crisis.

8/8 I cannot contain my excitement. It feels like January of 2020 with a huge wave coming that no one realizes yet, but in a much better way. What a time to be alive!! Check out the original paper: arxiv.org/abs/2307.12008

There are two types of programmers:
1) free(mybuffer);
2) "Thank you for playing Wing Commander!"
Is there a good word or term for a number that is in [0...1]? For example what should I name a method parameter that interpolates over a curve? curve.getPosition(u) where u is in [0..1]? #gamedev #programming. Just calling it u makes me feel like a mathematician :P.

I was hoping to have this book finished by SIGGRAPH, but I've decided to take a little longer to do everything right without being rushed. The book is turning out to be amazing, and it will definitely be worth the wait. I will have some preview materials available at SIGGRAPH.

This is a good presentation about optimizing performance. Contains only one low level optimization (pack hash key to 64 bit int). Optimizing code isn't about SIMD or multithreading. It's understanding what you are doing.

As an aspiring brain scientist, my project was to discover the brain implementation of Opponent Colors Theory, the accepted explanation of color appearance. It took 20 yrs of trying (& failing) to find the corresponding neurophysiology, to realize the theory is wrong #color 1/8

I'm all in on var in both C# and Java. I find that the less boilerplate code you need to read, the easier it is to follow what is going on and using var definitely helps there.
