The documentation doesn't explain how it uses the webcam - can anyone figure it out?

I think of it as: computing the chain rule in the order such that we never need to compute Jacobians explicitly; only Jacobian-vector products. I also didn't totally grasp its significance until implementing neural networks from matrix

It's already suspicious that the author left a bunch of non-math LaTeX commands in the abstract on arXiv. You proved one of the most important open questions in the history of humanity, but couldn't be bothered to make sure the ab

This is so cool. It makes me wonder what kind of amazing simulation software is behind closed doors in car companies.

FYI, this software is Windows-only for now, but there appears to be an active effort to make it cross-platform: https://github.com/ange-yaghi/engine-sim/issues/2#issuecomme...

My understanding was that those materials are more like electric motors and fully assembled control PCBs, not sheets of steel and spools of insulated wire.

This is good news, but Milwaukee is primarily a power tool company. Bringing power tool manufacturing back to the USA would be much bigger news. Project Farm is a YouTube channel that reviews tools. I've noticed that most of the made-i

I'm not even a CAD user and I'd contribute to some large-scale fundraiser to improve open-source CAD. Hopefully plenty of mechanical engineering shops will see the value in contributing. Expensive specialist developers are needed,

How user-hostile. With all this cloud nonsense the need for effort and funding in open-source CAD is greater than ever.

Many features in IDEs like "jump to definition" and "find references" are already designed for reading code. Reading code is a huge part of software development, so generic software development tools should already be go

I got 8/10 correct. I don't read philosophy and I've never heard of Dennett before now. I used the following techniques: - If the question has more than one part, the answer should address every part. - The answer should not

If you store the total application state for each step then it's simple, but consumes lots of memory. If you want to store something more like a diff, there are choices. For example, you could have code to undo each operation, but you

My pet peeve is when AI researchers coin new terms for objects that can be described by well-established mathematical terms. For example, saying a neural network layer has "256 units" instead of "output dimensionality of 256&

vim is a line-oriented text editor. When using vim, my mental model of the file is an array of (mutually non-contiguous) arrays of characters, not a single array of characters. I expect the same is true for most proficient vim users. This i

Would be interested to hear a signal processing perspective on this problem. I feel like splines might be susceptible to creating false information (e.g. ringing/overshoot), but I don't know enough about it.

Nit: Jensen's inequality only applies when the "derived value of interest" is a convex function of the "easier variable".
