Agreed that Voronoi patterns emerge, but I'm not sure that they're using an explicit Voronoi algorithm to achieve that effect. I doubt it. It's more likely IMO that the Voronoi pattern emerges from the constraints of the simu

Their physics engine doesn't seem related to the bubble toy as far as I can tell (although another HN comment implies it is). The physics engine implements 3D collisions between solid objects, joints, springs, etc. But the bubble toy i

I absolutely love this and am curious about the technical details behind simulating soap bubbles like this (it looks like the code isn't available). Does anyone know what algorithm is being used?

In the specific section that I took this statistic from, whales seem to be included: https://ourworldindata.org/mammals#wild-mammals-make-up-only...

Where are you seeing that this statistic is only about megafauna? I know the article talks a lot about megafauna extinction, but the specific statistic I posted does not mention this, at least that I can see. https://ourworldinda

An anecdote: my mother dropped out of law school when she was younger. She finally went back to law school in her 50's, graduated, and is now a practicing lawyer in a field she is passionate about. Taking the time to go to law school w

I'm interested in understanding this comment but I don't know where to start. I love the way Reaction Diffusion simulations look and I've coded it up a few times. But I don't understand what you mean by "species vs

This is amazing! Honestly one of the first uses of GPT3/DALL E that has held my attention for longer than a few seconds.

I've wanted something like Estigator for a long time! Unfortunately, it seems to be broken — it's not possible to add a specific type of estimate.

Wow, good point! I suppose the thermal printers that I've hacked around with are probably very dated in comparison.

I'm a huge fan of this. There's something magical about receipt printers. I love the idea that there is a long, infinite canvas which can flow from the printer. And part of the allure is the clunky slowness of the printer and the

I disagree. Firstly, I believe you underestimate the amount of work Jason does and the amount of stress he is under. I've read Kottke.org since I was a kid, and it's the only blog I still regularly read. There's a reason it&#

Totally agree. I assumed I was seeing an example of the editor!

I recently started using Linear at my new job, and I am a big fan. 1. It's snappy. Moving between issues and views is a breeze. 2. The UI is extremely functional and consistent. 3. Great keyboard shortcuts! Using Jira felt like having

I'm not sure I understand the distinction you're drawing between UX/UI and graphic design. To me it seems obvious that the concept of a "design system" has been around for a while and has been applied universally in

by astroalex 5y ago
That's not correct. A quick search using Google's Ngram viewer shows that "design system" peaked in 1986, and had quite a long history before that too, starting in the 1960s. https://books.google.com/ngra

I've been following the development of Shader Park for a while, and I'm so excited to see it come out of alpha/beta. It allows folks who aren't necessarily familiar with writing shaders to create amazing interactive 3D g

Shaders are programs that run on a computer's GPU, rather than the CPU.

Interesting, I have not heard of that! Thanks for the suggestion, I will look it up.

I have always been terrible at mental math. Numbers are goop to me. I can create systems which process the goop, but when I try to play with the goop directly, it's like the numbers are mentally "slippery" — I can't get

I could be wrong but I think they built their product on research that was already open and public. I believe the technique predates the company. Their "moat" was never the mapping algorithm itself; it was the suite of tools (hard

What art does have intention, in your view? And by what criteria do you evaluate whether art has intention?

I completely agree. I think in the case of Lightform, their core projection mapping algorithm is already public and has open source implementations. It's called "structured light". A quick search turned up this open source i

I believe that's different. The top 29% of the Burj Khalifa is unusable by design -- its only purpose is to make the building taller. I believe the OP's point is that when usable space in a building goes unleased, it makes it hard

If you're serious, send me an email at alexmiller@spacefiller.space! I would honestly love to hire someone to do a bit of grunt work.

Thank you! They're made with Java-based Processing ( https://processing.org/ ), although I have a new JavaScript/WebGL version in the works.
