Broadly speaking, "computational materials science" has been a thing for quite a while, and has been responsible for the majority of academic supercomputer time allocations for decades.

Yes, they are still supported, though 'modern' Fortran style discourages using them for new code.

Not saying Putin should be underestimated. Even if his strategic cunning is on the level of a village idiot, he clearly has a lot of men and material to throw into the meat grinder. And pretty clearly he doesn't give a shit about casua

Planning the lightning strike and capture of Kyiv for decades? Truly a strategic genius, Putin is.

Indeed. And if anything, if Ukraine would have accepted such a "peace" settlement, the result would only have been the mysterious green men appearing in the next regions in Ukraine near the border. Rinse and repeat.

I liked Termination Shock and I don't regret spending the time to read it in the slightest. However, to me, compared to the Baroque Cycle and Anathem, my favorite works of his, Termination Shock was, how to describe it, non-memorable.

I've never used a mainframe, but I did manage to introduce a small performance regression in gcc that someone complained about (I did fix it, yes). ;-) Turned out that s390 couldn't fuse cmp+jmp when the operand was a 8-bit value

TBH, I don't really think they compete in anything like similar markets. You buy a DGX A100, or a cluster of them, for training and running large deep learning models (or for doing "traditional" HPC). IBM's solution is m

I fully agree reducing CO2 emissions should have a high priority. Which for fossil fuels would mean a quite substantial tax on the fuel volume, but for EV's it's trickier since electricity is used for many other things, and electr

Even if we give it a bit of slack and make it a third-power-law for taxation purposes, it would still mean a large increase in tax for heavy vehicles. Or IOW, currently heavy vehicles are free-riding, with lighter vehicles providing much of

It's quite tricky actually. There's other negative externalities from car usage apart from the energy usage, like tire and brake dust, congestion, accidents, and road wear. And using up limited space in cities for parking. Etc. et

In the sense that both are flying things loaded with explosives heading towards your ship, no there's no "fundamental" difference between them. In practice, there's a world of difference. Drones are cheap and slow, but c

The shell itself flies considerably longer, although 20mm shells start to slow down and drop much more quickly than even slightly bigger shells like 30mm (see e.g. the Goalkeeper CIWS for a similar concept using the same 30mm gun as the A-1

I only read the abstract and very briefly skimmed the article, but... So it claims that it doesn't require bipartisan agreement to reach 'optimality'. Fine, I won't argue that point as I haven't looked that deeply

Military diesel subs have snorkels so they can run their diesels when they are at periscope depth. If they need to go deeper (or don't want a radar-reflecting snorkel sticking up over the surface) they shut down the diesels and rely on

AFAIU for 'heavy' 3D applications like AAA games the BW over the PCIe bus to the GPU can be a lot higher than what comes out of the cable to the screen. So just sending (compressed) pixels is not necessarily a bad remoting strateg

Perhaps an even bigger(?) problem is building out the software ecosystem. To be a serious alternative to something like ARM, or even RISC-V, you need support in OS kernels (at least Linux, depending on which market you're going for), L

If you hate exercising you won't do it for 1.5h/day anyway. If you enjoy exercising, you get to do something you like, which on top of that increases your (healthy) lifespan. Win win.
