less far sight, dichromatic color vision, over-optimized for low light. a cursory glance did not find studies on cat peripheral vision, but would assume it's worse than human if only because they rely more on audio

yeah, try matching a human eye on dynamic range and then on angular speed and then on refocus. okay forget that. try matching a cat's eye on those metrics. and it is much simpler that human one.

problem is, expensive cameras that Tesla doesn't use don't work either.

If those persist in opaqueness, say "confess, or I fetch Ghidra". If even this does not help, rm -rf is your friend.

We never ran stackless/greenlet under windows. And pycoev was setcontext(3)-based, so no windows either. But I can imagine what that code did there...

It was memmove() on each task switch. So you could forget about d-cache. And that killed performance on anything but benchmarks.

idk stackless dates back to 2005 at least, most likely earlier. greenlet which is sort of minimal stackless .. before 2008 pycoev which is on one hand greenlets without memmove()s, on the other hand sort of io-scheduled m:n threading I wrot

Where I lived all this summer the only transport infrastructure that was available for the last 80 years since the reservoir dam was completed was an old diesel tractor and an equally old motorboat with an evil 2T outboard, or a 3 km walk t

I beg to disagree. The 5210 was the best, it was indestructible, cheap, kept its charge and still was functional even if you rode over it in your bulldozer. The 8110 was the second imo, but only for the style. And the 3310-ish were the runn

heh, in mid-2000s all I had were a batch of misbehaving SATA controllers under freebsd, and an (actually quite well-written core of a) linux driver was all I had to work with. Without that, we would have probably just switched hw, because t

Oppression helps disseminate knowledge. For example in Russia it's common knowledge nowadays to the extent that babushkas discuss relative merits of various VPN services while gathering shrooms in the woods.

your comment reminds me of a rant by a severely clueless person who insisted that we must conserve water despite living on an island in a middle of a second largest european reservoir. which is utterly pointless.

well, yes, I like the smell of 2T exhaust in the morning. still, even my yamaha majesty 250 of 1992 (4HC-edit) only ate 3.5L/100km despite hauling thrice the mass of that same ovetto.

But the scientific method does work. So we observe the experiment kindly undertaken by Mr Musk. And then when some results happen we decide. Remember, development of the R-7 into the most reliable expendable booster took about 40 years and
