A lot of the natural gas plants are combined cycle, which includes a steam Rankine bottoming cycle.

Uh? IT for higher ed is not that different from any other enterprise IT. I used to work at a university, although I worked on the Linux/HPC side of things we did have regular contact with the IT department. So things the IT department

Yeah, vsphere has a mile-long list of enterprise checkbox features that the sales managers can overwhelm the CIO's with on the golf course. Kubernetes might have success, but AFAICS Kubernetes also sort of involves a new way of archite

There is a PWA you can install, with it's own icon and everything. Yes, it's a not-even-glorified-web-browser, but meh, it works (for some definition of works).

Not to mention when you had multiple devices you had to piddle with physical jumpers so no two devices shared an IRQ. Good ol' ISA.

Blast from the past! When I was a kid we had such a floppy tape device connected to a 386 or 486 computer my parents had. I think it was a Colorado Jumbo 250. I think the actual capacity was 125MB, but the drive or the backup software had s

I recall Opel was owned by GM already before WWII? And iy was only relatively recently that GM got out? (Ownership aside, Opel has been producing cars made in Europe for (mostly) Europeans for AFAIK the entire post-WWII era.)

Oh, right, yes. But that's just because 1/T occurs in many formulas and thus it's often convenient to work with it instead. No exciting new physics hiding there. ;)

A cool (ha ha!) solution was the old Cray XT3/4 supercomputers, which were air cooled. But instead of a battalion of tiny fans, each cabinet had a single huge fan at the bottom, blowing air vertically through the cabinet (the boards we

I suppose in some desert-ish climate the extra moisture given to the air doesn't rain down nearby but moves with the wind somewhere far away where it rains. So there might be an effect of using locally precious water even if it's

Not sure what Google specifically is using here, but PG25 (25% propylene glycol, 75% water) is somewhat common in data center applications. The glycol takes care of avoiding microbial growth.

Intel should have split 15 years ago, ideally, but I'm not sure that splitting now isn't better than not doing it. If they fail to catch up to TSMC, it's possible that the manufacturing branch will drag the design branch down

Sure, the details would certainly have been different, but my argument is that the end result would not have been that different from what we saw playing out. My quick 5 cents for what might have happened in the interim: - Without a separat

Perhaps the government should have required Intel be split into a fab business and a chip design business (as Intel has planned to do itself but hasn't been able to, for reasons). The chip design part can survive on its own without sub

I suppose this is a FOSS solution for the roughly same space occupied by commercial tools like Origin, that are very popular in some scientific communities. They can be useful if you have other tools (e.g. measurement software) that already

To nitpick at least as of Apache HTTPD 1.3 ages ago it wasn't forking for every request, but had a pool of already forked worker processes with each handling one connection at a time but could handle an unlimited number of connections

If you're not wedded to docker-compose, with podman you can instead use the podman kube support, which provides roughly docker-compose equivalent features using a subset of the Kubernetes pod deployment syntax. Additionally, podman has
