Heh.
1.Create fast modulus quad M for dword D for the first 2000? 200000? (xM)D
2.Eliminate 0b,101b
3.Divide using vrcp14ss/vdivss with correction. Use fast square root too using rsqrt14.

Cold_Miserable commented on Why No AI Games? franklantz.substack.com/p... · Posted by u/pavel_lishin
Having recently considered playing Dwarf Fortress(and quickly rejecting it for UI issues and overall tediousness), it seemed like a game that would benefit from an LLM backend. I'm curious what sorts of world history an LLM could come up with. It likely would be a lot less efficient than the current system, but interesting nonetheless. I think it would be easy for devs/modders to add a way to supply an API key to an LLM and experiment there.
Also having recently played a run of Civ5(before burning out because the late game is tedious and the overall game so unrealistic), I thought that good AI would help 4x games remain epic while letting the user choose their level of tedium. It would be nice, for instance, to manually go through the early game when management is easy and exploration is fun, only to turn that over to an AI at some point(and you generally do with autoexploration). Same thing with other eras though. By the time I'm in the late game and have a large empire, I'd rather focus on diplomacy and moving armies, not city management or worker management. I don't want to commit to fully giving up on those aspects of the game though. It would be nice to, say, automate war mostly but be able to jump in if I want to micromanage for a few turns.
Distant Worlds I and now II has had full automation for ages.

I've not made any accusations, nor do I think that the elites are not to blame. I said that "money printing" is not the problem here. The reason it's not the problem is because the quantity of money simply reflects savings. By focussing on "money printing", you're missing the actual problems. Arguably, that's the point, since the elite tend to do well when money is considered a scarce commodity.
Sure, spending might cause inflationary effects, but that's orthogonal to quantity (flows not stocks), but then economics is the science of confusing stocks with flows.
"Currency printing" and inflation are exactly the same thing.

I suspected this was because the vector units were not wide enough, and it seems that is the case. AVX2 is 256-bit, ARM NEON is only 128-bit.
The big question then is, why are ARM desktop (and server?) cores so far behind on wider SIMD support? It's not like Intel/AMD came up with these extensions for x86 yesterday; AVX2 is over 15 years old.
AVX2 isn't really 256-bit.
Its 2x128-bit.
Human inner ear is worse than a $3 IMU in your average smartphone in literally every way. And that IMU also has a magnetometer in it.
Beating human sensors wasn't hard for over a decade now. The problem is that sensors are worthless. Self-driving lives and dies by AI - all the sensors need to be is "good enough".
Human hearing is excellent. Good directional perception and sensitivity.
Eyesight is the weakest sense. Poor color sensitivity, low light sensitivity, blindspot. The terrible natural design flaws are compensated by natural nystagmas and the brain filling in the blanks.
Idiocracy is the future.

Its 1024.
Hard drive manufacturers should be forced to use the correct metric.
It's a solved problem. The physics is simply such that it's really inefficient.
> ... we'd need a system 12.5 times bigger, i.e., roughly 531 square metres, or about 2.6 times the size of the relevant solar array. This is now going to be a very large satellite, dwarfing the ISS in area, all for the equivalent of three standard server racks on Earth.

The gist of it is that about 99% of cooling on earth works by cold air molecules (or water) bumping into hot ones, and transferring heat. There's no air in space, so you need a radiator 99x larger than you would down here. That adds up real fast.
A really painfully laboured way of just saying conduction.
I agree but the difference between the French and the British is the French really didn't have a choice (they got physically invaded).
You could make a very good case that for Britain entering into WW1 was a catastrophic and ultimately unnecessary decision. And you could make a (much more controversial but I think also true) case that entering into WW2 was also not necessary and ultimately fairly catastrophic.
Yet the British elites chose to do both. Pride, hubris, stupidity, maybe well deserved, call it what you want, but in the end British power was given away cheaply. I think what the US is currently doing is foolish but as you say there's also a sort of inevitability about it.
Edit: You could also add the Soviet Union to this, an even more recent example of the end of an empire. Towards the end during the Gorbachev era policymaking went from relatively "normal" (by Soviet standards) to extremely bizarre in a short space of time
Britain should have stayed neutral like Sweden and Switzerland instead of getting economically devastated.
I've always thought the 8087 was a marvelous bit of engineering. I never understood why it didn't get much respect in the software business.
For example, when Microsoft was making Win64, I caught wind that they were not going to save the x87 state during a context switch, which would have made use of the x87 impractical with Win64. I got upset about that, and contacted Microsoft and convinced them to support it.
But the deprecation of the x87 continued, as Microsoft C did not provide an 80 bit real type.
Back in the late 80's, Zortech C/C++ was the first compiler to fully implement NaN in the C math library.
x87 should have been killed off. It would have forced lazy game developers to use SSE around the 2005 era.
