The "can be arranged" is the tricky part. E.g. you might know from context that some states are impossible (where the probability distribution is zero), even though they combinatorially exist. That changes the entropy to you. That

Both parties contributed to and maintained the status quo, because they both profit from it. Game theory works out and both try to balance their power roughly 50/50 and keep everybody else out of the game. All topics are polarized to t

If you mean people hired to hire other people, then yes, strongly agree. The entire thing is built on the assumption that your company will have a high turnover rate. That is something that should be avoided by employers as it for one incre

I generally agree, in the long term there will be far less need for teachers, as there will be less need for human jobs to be taught. However, creating many individual systems which are better than a human in a specific area each is very di

If the technology is truly as capable as humans in many domains (and that might still take a while), it will not matter anymore whether it is a good teacher or not. The need for (and thus value of) human labor will depreciate and so will it

Discrete spacetime does not necessitate a regular and nicely ordered tesselation, it could be pure chaos or be non-geometric. Before we thought that energy, mass and matter were completely continuous and that turned out to be wrong.

It is true that Vulkan usually is behind DirectX by two to three years, but it gets there eventually. Keep in mind that Vulkan tries to cover a wider range of devices and platforms. Also, in my experience as a contributor to GPU HALs, Vulka

I have found that procedural generation tools such as Blender are a good substitute for (single-player) Factorio. Especially the node DAGs such as shaders and now geo-nodes feel a lot like belts, inserters and assemblers. Plus in the end yo

When working with meshes what you generally want is is quads, not triangles. The reason is that quads form nice closed loops. Further more you would only allow quads to meet in 3, 4, or 5 edges per vertex. The 4 edges per vertex is the &quo

While I don't think we live inside a simulation or that there is an outside, you might enjoy the book Simulacron-3 [0] or its movie adaptation Welt am Draht [1]. It is about the protagonist realizing that they are an agent in an econom

I sometimes play with this thought as well, and I think we will see more of it as AI technologies allow for more realistic behavior of virtual agents. The reason why I think having virtual agents instead of real players is important is beca

Many 3D content creation tools such as Blender [0] have SDF [1] (e.g. metaballs in Blender) and CSG [2] (e.g. boolean modifier in Blender) features. But these are rarely used as they can only define volumes, not surfaces. And we are usually

That would be true for a single node / single layer. But once the output of one layer is fed into the input of the next it is not just a linear combination of splines anymore.

The first question is why is there a divide between CPUs and GPUs in the first place. Yes, the gap is closing and both categories are adding features of one another but there still is a significant divide. IMO it has to do with Amdahl'

It also uses a Merkle tree to compress the snapshot versions associated with commits. But the actual commit structure builds on top of that. A pure Merkle tree or forest would only give you a set of overlapping snapshots, without any direct
