Great post. Full of useful tips I always need to remind myself of.

I had one til a few months ago!

The closest thing I've been able to find so far (which seems to have been under slow development by 1-2 contributors for the past couple years) is https://github.com/MPSQUARK/BAVCL which is based on ILGPU. I'll probably be keeping an eye on it though.

Unfortunately I don't believe NumPy has any built in accelerations (other than being a C library which is fast already), though I don't really know the ins and outs. There are Python libraries that use the NumPy API or otherwise do some stuff to accelerate it on e.g. CUDA, but the Numpy.NET library as far as I know uses its own embedded Python + numpy, so as far as I can tell that wouldn't be an option.

Unfortunately not, though I forgot about SIMD! It doesn't seem to support arbitrary-sized matrices or arrays out of the box, though I guess I could index the vector type myself. Still, it doesn't offer the operations I'd like, as far as I can tell.

Thanks though!

Got an XPS 13 9350, works fine, bluetooth and all, though I upgraded Ubuntu and the kernel and the integrated webcam hasn't worked since, which I still don't really understand.

This may not be relevant since I have a different gpu and am on Ubuntu, but when I installed proprietary drivers I didn't have display either because I was using a version of the driver that was too recent (whether due to dropped compatibility or a bug I don't know). An older one might work!

Google en passant

There might be some kind of trust system that could work. I have no idea of course but I'm envisioning something like Stack Overflow's system and a bit of community correction and authority à la Wikipedia.

Why can't the government just build it as a public utility?

That's actually not true, right? https://www.iea.org/data-and-statistics/charts/global-co2-emissions-from-transport-by-sub-sector-in-the-net-zero-scenario-2000-2030

In 2019 there are 6.08 Gt from road vehicles compared to the 0.87 Gt from shipping. That's just overwhelming.

Yeah, I saw a link to a study that modeled outcomes within the next fre decades where acidification kills enough marine life and favors the reproduction of other microbes. Something about either low oxygen in the oceans and/or the atmosphere, or maybe a dangerous increase in stmospheric toxins resulting from that.

Maybe I'll try and find it to verify.
