I'd say some similar long-term chipping dynamics would apply (between river-stone and certain types of icy-water flow) and sphere is then just one of many smooth shapes that you can get out of such a system.

A near-perfect sphere? sure! Only looks-like-a-circle from some distant projection. Vortices in a near-2d-flow like a river will absolutely be circular, vortices need to be coherent in some plane in order to sustain themselves. The specific

A circle/sphere/etc is a special fractal where the curvature is the same across all scales.

Agreed (though circle is pretty common, but,) has anyone ever seen any trace of a mandelbrot-shaped feature anywhere in nature? (I mean the whole set, not just seahorses/etc) I'm on the hunt!

Sounds like geosmin is actually not that pleasant on its own.. I like petrichor personally but can imagine the earthy aspect on its own might not be entirely pleasant.

Good old 'petrichor'[1], I've never noticed it emanating from a human. I wonder if geosmin is used in any fragrance-products though, or even if specific skin flora (bacteria) might produce it? https://en.m.wikipedi

Kinda more 'primes from images' (w/a tiny area that can't be used) than 'images from primes'. Still cool though!

I read about a blind guy who had a camera hooked up to an array of electrodes on his back and eventually was able to 'see' using it. That was a long time ago, but it looks like it's still a thing nowadays, see 'Brainport

Happy holiday season to everyone on HN, you are all awesome! Amazing work by dang and sctb too keeping the discussion at such a high level, best wishes for 2020!

I wonder whether Gentoo might have an edge here (even in general beyond just jdk) since nearly everything on the system is built with the local CPU as the optimisation target? It certainly reduces the need to not be 'feint of heart&#x2

About to go to sleep but will gladly respond to any questions about Houdini in the morning. H doesn't usually seem to get much interest at HN, but I think it is currently one of the ultimate hacker playgrounds myself! At least PDG migh

I reckon "the first byte you upload" is being used as a turn-of-phrase here, and is not meant not to refer to the specific bit-sequence of each (or the first) byte of the upload. Rather the idea that the (eventual) metadata of the

The main thing that's maybe interesting about this weird old project (I have learnt a bit more python since back then) is that it can correctly decode compressed UPR-strings as commonly copy-pasted on the UltraFractal email list (a str

The demoscene (actual code art) isn't even mentioned in the article!? Makes it hard to take it seriously, and gives the whole thing a stuffy and academic kind of feeling. Has anyone read the book? ("The Software Arts" by Warr

One alternative is 'Process Physics' which is not widely accepted but has a fundamentally different explanation for dark matter: Turbulence in the in-flow of space into matter. This flow is PP's model for gravity itself, as i

To add a bit of background, this is a new 'Top' (for 'Task Operator') context in Houdini, a new class of licensing from SideFX and eventually it will be a new standalone application as well. Currently you can try out PDG

It surprises me that the article doesn't mention the idea that intentional maintainence and nourishment of ones own intestinal flora is one way to help defend against unpleasant intestinal events.

Apologies it does sound[1] like an absolutely perfectly shot 35mm frame can theoretically hold up to 20 million pixels-worth, but I've never seen this in practice in the vfx industry, it's almost always less than the ~3 million pi

I work in the film industry, a 35mm full-aperture negative scan holds only about 2048x1556 pixels-worth, and even at that resolution the film-grain blobs are several pixels across (especially in the blue channel).

Could it be used for things like vending machines perhaps? You would still need a cellphone to pay but the machine would only need an antenna and cheapish chip to make it work.

Minor nitpick really but maths is a subset of computation. This is made most obvious by it's requirement of consistency. Gödel showed that you can't cover all possibile values and preserve consistency at the same time, but computa
