There have been some sodium cooled designs that have used a closed cycle gas turbine using nitrogen as the working fluid for the secondary circuit, in order to avoid any issues with sodium-water reactions with a traditional steam Rankine se

I have a small benchmark program doing tight binding calculations of carbon nanostructures that I have implemented in C++ with Eigen, C++ with Armadillo, Fortran, Python/numpy, and Julia. It's been a while since I've tested i

I don't think the situation is that comparable to python, since in python the library has to be present at runtime. And with the dysfunctional python packaging there's potentially a lot of grey hairs saved by not requiring anythin

If Rust and static linking were to become much more popular, Linux distros could adopt some rsync/zsync like binary diff protocol for updates instead of pulling entire packages from scratch.

Does this evolution of the Vulkan API get closer to the model explained in https://www.sebastianaaltonen.com/blog/no-graphics-api which we discussed in https://news.ycombinator.com/item?id=46293062 ?

Kind of, but not really. Rayleigh scattering is elastic (only the direction changes), whereas Raman scattering is inelastic (energy, that is color changes in addition to direction) scattering.

Some Fortran compilers also did this. MS Powerstation Fortran at least, IIRC.

If you want to make an argument for something else being the representations of boolean variables than 0 for false and 1 for true, one could make the case for true being all bits set. That would make it slightly easier to do things like mem

The (minor, but still) optimization that is enabled by assuming _Bool can contain only 1 or 0 is that negating a boolean value can be with x^1, without requiring a conditional. That being said, for just testing the value, using the zero&#x2

Amusingly(?), the Juha Sipilä character mentioned in the article later became prime minister in Finland from 2015-2019.

Maybe when the doors open the characteristic smell of that station enters the cars?

If I had to make I guess, I'd go with the dogs recognizing the smell. Dogs apparently don't have terribly good vision, but as I'm sure we all know, a very good sense of smell.

Because the heat and pressure from the propellant and rifling vaporizes or rubs off some of that lead. A very small percentage, granted, but still. Particularly for unjacketed bullets like 22LR. Even jacketed bullets tend to not be jacketed

I recall there's one factory on the planet still producing TEL, so once they decide it's no longer profitable it's over. Aviation gasoline is probably the one market that still keeps it afloat, when/if piston aviation sw

That's true, and without any legislation or such prohibiting lead they would most likely have continued to use it as anyone who would have phased out lead would have been at a competitive disadvantage. But once it was banned, everybody

Good point. Though too late in this particular case, since the battery was also busted, I ended up e-wasting the machine.

AFAIU the Debian i386 port has effectively required i686 level CPU's for quite a long time (CMOV etc.)? So if he has an older CPU like the Pentium it might not work? But otherwise, yes, Debian 12 should work fine as you say. Not so lon

At least soot from ships is an issue in high latitudes, as it turns out that the soot reduces the albedo of the ice and it thus has an outsized global warming impact.
