Beryllium is a good plasma facing material (low Z, low retention, low activation) and acts as a neutron multiplier, but it's highly toxic: only a few months ago ITER announced they scrapped the design of the first wall because working

Rewriting the old Fortran code in C will probably make it slower with new bugs. A smarter thing to do when picking up terrible code written by physicists is to document everything you can, write tests and then start refactoring bit by bit u

I'm curious, what are you considering for stating that deuterium is not renewable? AFAIK there's an essentially limitless supply in the form of HDO in the oceans[1] and there are cost effective methods[2] to isolate it. [1]: http

Unfortunately is pretty far from "less than 10 years", which I guess you got from the half life of tritium. Tritrium radiocativity, in the form of tritium retained in the plasma facing materials, does contribute in that order of y

Only tangentially related, but has anyone ever tried to eavesdrop on DSL? Modern DSL (VDSL2 in particular) is essentially a HF signal guided on an unshielded twisted pair (with line stubs and what not), so it should easily leak out and radi

I think the general direction where Wayland, Flatpak and other similar sandbox frameworks are going is that of users running proprietary, untrusted and more or less user-hostile apps on the desktop, just like on tables and smartphones.

Note that Gödel's incompleteness theorems do not apply to just any system of logic: they are about particular formal systems that can prove certain facts about the arithmetics of integers. So, for them to fail, it doesn't even t

To me it's quite sad that for a lot of things, the "standard" way of doing something is not actually part of the standard (XDG portals, third party protocols, etc.). Yes, X.org is old, bloated, unmaintainable and whathever, b

I don't think radios use a PLL to demodulate the FM audio: the signal has a huge "pilot" tone at 19kHz that you can match to get the first part of the spectrum, mono audio (L+R channels), and at double that frequency you know

Unfortunately there is still the issue[1] of fingerprinting. Until it can spoof the TLS handshake of a typical browser, you get these "Just a quick check..." or "Sorry, it looks like you're a bot" pages on about 80

It's pointless arguing whether it could have been economically successful, we'll largely never know because people got scared.

Comfort tale or not, my country banned it completely 40 years ago by popular referendum. I don't think the economics were what people had in mind one year after the Chernobyl disaster.
