Even as far back as ancient Egypt [1]. And they had dentistry too [2]! Any time in history where they milled grains into flour with stone, you can see this pattern. In fact, it can be used to differentiate certain agricultural vs non-agricu

This is super cool. As another commenter said, I'd like to see this for other natural dyes (onion skins, walnuts, etc).

Yes. You can add whatever passwords. It asks you for a URL but you can put anything in.

reddit's printsf subreddit is the best place to discuss sci fi and fantasy imho. Low spam rate, good, in-depth discussion, and obscure recommendations from people who genuinely love the genre and aren't judgy about it.

Pandoc! I write markdown and generate HTML pretty straightforwardly.

Agree. People act like peer review is this unshakeable tenant of the scientific method, when it only became widespread in the 70s and 80s. To my mind, papers written these days are usually a lot worse than those written before peer review,

Nice article, thanks for sharing!

Really nice article! I have some OpenGL familiarity and tried out Vulkan but bounced off of it due to all of the up-front complexity just getting something running. Might give it another shot now!

Sometimes, the fact that one implementation includes it can make it actually more difficult to standardize, if there are some implementation details that are disagreeable (see GNU's nested functions)

Nice article, thanks for sharing! Been implementing my own string type for fun recently and this is a useful reference!

Surprisingly, there exist people doing GPU programming outside of ML. I work in high performance computing and lots of people write CUDA code.

Knowing as many people in the robotics space as I do, I suspect the demo may not be completely "pre-baked" but it is almost certaintly highly selected. Often they'll try the demo many many times until they get a clean run-thr

EmpLemon has a video about this. He argued Blair Witch had the highest multiple (~1200x) https://youtu.be/PYmi559SpWI?si=_oTiHXTili5K6W5s

That's a neat method! I hadn't seen it before.

Yeah, looking at it again it's not as accessible as I remember. It's quite mathy, but well-written. An epsilon-ball is just a "ball" (circle or sphere analogue of dimension n, where n is the number of inputs) of radius e

Actually, quite a few algorithms can provably find global optima. However, there's a property of such algorithms that makes them (often, but not always) impractical for many problems. Any algorithm which can find a global optimum must

I use Fortran for some research codes (I also use Julia and C++). The main advantage of Fortran, to me, is that it is very easy to write very fast code, and has very few foot-guns. The latter property also means it can be quite difficult to

Yeah, "dense" kind of under-sells it. Given the distance to its host star, I would guess that this must be a gas giant core that had its outer envelope blown away? Otherwise this seems hard to fit into our typical models of planet

This is an awesome way to widen the reach of their research. I did a similar video for some of my PhD research in spacecraft propulsion and plan to make some videos for future papers I publish.

I love this? I'm not sure if it's ironic, unironic or what but I'm digging it.

I use fortran in my day to day work and most of my work has been modernizing and refactoring an oldish code. Its amazing how nice it can be to work in once you've removed and reorganized the legacy cruft.

> They do no work, take all the profit, and obstruct research and the spread of knowledge. Those are some of the worst scums of capitalism. Amen. Pure rent seeking parasites.
