Not the author, but I assume that to make it work with 32 bits integer coordinates, some operation (like multiplications) need extension to 64 bits. If we want full hardware support on 64 bits CPUs, that's the limit.

This is ridiculous, there are plenty of stars and most of them are red dwarfs with tidally locked rocks blasted by flares anyway

Having something Turing-complete is surprisingly easy, and it hides everywhere. The repository have a small document that explains how you can use printf() as a computer : it can performs additions, logical union and negation, which is enou

There are lots of C compilers (LCC, TCC, SDCC, an army of hobby projects C compilers) available as open-source. I am curious about what results would be for something like a lexer + parser + abstract machine code generator generation for a

It's stochastic monkeys, but enhanced with a really good bias towards coherent prose, built upon a gigantic corpus.

Hot take : the whole LLM craze is fed by a delusion. LLM are good at mimicking human language, capturing some semantics on the way. With a large enough training set, the amount of semantic captured covers a large fraction of what the averag

The plan went from the AI being a force multiplier, to a resource hungry beast that have to be fed in the hope it's good enough to justify its hunger.

Significantly faster compilation means less friction to iterate ideas, try things, which in the end lead to more polished results. A nice interface is agreable, but maybe there are diminishing returns when you pay it with large compile time

It's not a way to boost a signal. It's using the Sun as a (gravity) lens, with probes at the focal point to gather the image. Because it's a very large lens, that's allow to have a massive zoom on whatever object we are

I had the same experience with computational geometry. Very good at giving a textbook answer ("give a Python/ Numpy function that returns the Voronoi diagram of set of 2d points"). Now, I ask for the Laguerre diagram, a varia

Fixing the topological naming issue, in the mainline, what a game changer. I am using Freecad for Actual Real Things. I learned to work around the topological naming issue, but it cost me time, and it can make parametric models quite brittl

I rage quitted OpenSCAD for FreeCAD :p For real, because I am way more productive with FreeCAD. FreeCAD allows to work in term of topological features like surfaces, edges, etc which is, in practice, very cumbersome with OpenSCAD.

That flap is already a legend, kept at it even mangled by hot plasma, crazy accelerations and pressures, spitting molten steel at the camera. What a role model, the little flap that could.

A well-made TUIs is really ergonomic and clutter-free. It can be maintained to high standard by one person. It doesn't take a lot of efforts to make composable tools, ie pipes. It uses little resources even for fancy TUIs. GUIs can be

You need to dice your scene in many well formed elements (it's tricky, lots of edge cases), and you are simulating diffuse light only. Point sampling achieve the same results without a complex preprocessing step.
