Chrome has a browser extension API which allows plugins to access all cookies, but its use is considered suspicious and a red flag; an extension which uses it would generally get caught during initial review. However, Chrome extensions are

Revisiting this. Isn't it a bit of a red herring to enquire about the number of 2-faces that an n-simplex has? It still only has n+1 vertices. A 768-simplex may have 75.5 million faces but it will still only have 769 vertices which com

I believe the answer is: (n+1)!/((k+1)!*(n-k)!) where n=768 and k=2 Or about 75.5 million triangular faces. Which explains a lot. Thanks for that.

> The real problem is that in dimensions that high, the point set probably already is the hull and all this is a zero signal gain operation. Well, if I have 10,000 samples of a 768-dimension volume, most of those points will probably be

I've been trying to use convex hulls to explore ML embedding spaces. However, the dimensionality (768+ dimensions) seems to crash established options like QHull[0], even with 64GB RAM (and 16 CPU cores, albeit libqhull is not multi-thr

Could you pirate the database, then hide behind the fifth amendment to not reveal that you're a pirate while simultaneously asserting that you never agreed to any EULA? I'm not sure what the legal rights are here. I'm certain

Correct. To be pedantic, there is a built-in 16kB ROM starting at address 0x00000000 with RPi's open-source BootROM burned into it at the time the silicon is manufactured. There's no publicly-known way to write to this. It's

In fairness, many of these will end up in consumers hands shortly after a bit of additional value-add. On the bare-bones side, that's things like JLC PCB stocking them for pro-hobbyists to get custom low-volume PCB's made with the

Very few loops need any real tuning. For most of them, an incredibly wide range of value works perfectly well. Systems usually have a lot of slack in them. It's hard for most field engineers to get experience tuning loops when there ar
