It's a feature of X (so works in any app running in X, not just FF and your terminal emulator). Wayland changed clipboard behaviour (along with many other things) and decided the selection clipboard was too large a security hole to keep. It's pretty useful though, so Gnome added it back, on top of Wayland. It's still a large security hole though!
Separately, PuTTY has a similar mechanism for copy, though this goes in the normal Windows clipboard.
US treasuries (bonds, notes and bills) are mostly considered as good as cash. They're used heavily in the international banking system (for payments, and as loan collateral themselves). They're also held to maturity by large institutional investors with predictable liabilities (ie payments) like pension and insurance funds. Banks will hold some of their assets (eg deposits) in treasuries too.
Also foreign governments and central banks will have holdings. Tether (the cryptocoin) is largely backed by US treasuries.
This is great: I've wanted a personal extension for a while (roughly to replace my userscripts but with more power and better sync) but was put off by it having to be public or manually installed. Now I can make this!
This is cool! The simulator was useful for understanding what was going on, I hadn't realised until I watched a few that the roons can push marbles out in between squares.
I don't see planning mentioned much in the article or comments. The Town and Country Planning act is a large cause of high development costs in the UK. Roads, rail, public works, nuclear power stations, onshore renewables and above all housing have all suffered significantly because getting things approved is so difficult.
Most other affluent nations have some form of zoning instead, which make planning much much easier. Most other affluent nations have more central control over planning too, which makes consensus over megaprojects easier to reach.
This feels similar to heat pumps being >100% efficient though? Perhaps a less misleading headline would be 'Very low-power LEDs also convert heat to light'
Ukraine's drones are already partly automated because of the jamming environment: they can visually lock the drone onto a target from up to 10km away.[0][1] They're also using drones that trail a fibre optic over several kilometres to avoid jamming.[2]
Well, the chargers won't be pulling 1MW continuously, so you can smooth this out by installing batteries with the chargers. The grid demand becomes a more constant trickle into the batteries co-located with the charger
