Luckily thanks to regulation the use of asbestos in new builds has almost completely been eliminated (I'm sure there are some uses somewhere where it's indispensable?), but there's of course a huge number of places where it t

Asbestos was also used as 'fake snow'. Famously the snow scene in the 'Wizard of Oz' movie was 100% pure asbestos.

I'm not a doctor or researcher in that field, but my understanding is that cancer is not 'one disease', but rather a huge number of different diseases which mostly have in common that they develop some kind of tumors. That&#x

I suspect that it's difficult to keep the post sufficiently still that the panels don't fall off those slots? Particularly if there's ground frost in the winters in your area. Of course it's possible to make it work, but

As an aside, yes the current trend of huge wheels with super low profile tires is idiotic. Hopefully sanity will prevail at some point.

No, heating only. I'd imagine trying to use them for cooling in the summer would easily lead to condensation and attendant moisture damage.

There is a lot of work to do to reverse the trend of increasingly locked down computing devices, particularly on mobile. But from scanning through this press release, this seems nothing more than the FSF doubling down on their failed RYF ap

'Old school' trash burning can produce quite nasty emissions. Not much of an issue with modern plants that burn at higher temperature and have some amount of flue gas filtering etc. Certainly beats landfilling and producing that s

My father replaced oil burning with an air-water heat pump. That is, the heat pump heats water that circulates in the same pipes and radiators that were used previously. Apart from installing the heat pump in the boiler room, no other chang

AFAIU GIL is still the default, and no-GIL is a build option, you can't select it at runtime. The big issue is what about all those C extension modules, some of them might require a lot of changes to work properly in a no-GIL world.

One way to think of SIMT is that instead of vector instructions you have a 'fork' instruction which turns on vector mode where the scalar instructions execute on all the vector lanes. Your SIMT code must then include a 'lane

Well, kind of hard to say anything exhaustive in a quick comment, but roughly advantages: - POSIX compliant, including dotting the i's. As opposed to, say, NFS which isn't cache coherent. - performance and scalability. 1 TB/s

Yes. AFAIU the cost of process R&D and building and running leading-edge fabs massively outweigh the cost of CPU architecture R&D. It's just a world of its own largely out the comfort zone of software people, hence we endlessly

If you're going for the enriched uranium route to a bomb, nobody is going to start with used nuclear fuel, because dealing with the highly radioactive spent fuel is such a huge PITA. If you're going for the U233 (from Th) or Pu ro
