"You can split photons into 2 lower energy photons, but can you split them into 3? If you can..."
You could have stopped there until you found that answer.

But hey, you voted for them.
"them", being any party that's been in power since then, of course, which means the vast majority of voters voted "them" in. Those who never vote or have only voted for parties who never made it to power can hold there heads up high, point and laugh. Except the Greens, of course, who don't want any form of nuclear power! :-)
"There is absolutely no excuse for the amount of fossil fuels we've shoved up power-station chimneys during the whole of my adult life."
True. And until very recently, no safe limits set on the emissions. Coal fired power stations were pumping out enough radioactive particulates to have closed down a nuclear power station. And giving away/selling the "clicker" to be used as hard-core/pathways, a highly toxic mix.
"The Coronavirus Act 2020 was ready to go suspiciously quickly - I suspect there are boilerplates."
Yes, pandemic planning was already done. What appears to have gone badly wrong was the provisions and supplies supposed to be in warehouses, ready to go. Much was either expired and unusable or had been wound down and reduced over the years under the guise of cost savings.
"See Trump's latest "US should fund safe schools before Ukraine". i.e. the false dychotomy to pull the plug on US weapons to Ukraine to help Russia."
I saw that comment. I was flabbergasted! How much did he do to stop mass shootings, especially in schools, while in power? My most stinging memory of his reaction to shootings etc was telling us the people advocating killing were "good guys" when someone drove a car into people. Although, since I don't live in the US, I may not know all I should or want to know about him.
"Egon Durban, a pro-Musk board director, tried to resign from the panel after shareholders voted to have him removed, but his request was rejected by Twitter in an SEC filing."
Wait...what? How does that work then? The owners of the company vote him off the board, he then tenders his resignation and *Twitter* refuse? What right to Twitter have to over rule the company owners? Is there something missing from the article or is this something weird about US corporate rules?
"However their EU Mandated WEEE recycling van is round in 15 minutes flat to cart the old "dead" machine and accompanying consumables back to the warehouse."
I've seen the opposite. Went in to commission a new printer and not only was the old printer still there, left by the previous printer company, the one that had replaced was ALSO still there, from the SAME previous printer company. Both the old ones were twice the size, half the speed and twice the running cost of the one we had just put in. They should have billed the original supplier for storage as they were leased items.
"This was a slight issue if you used a different manufacturers drive where one was actually 250GB and the other was only 249.9GB. So we started leaving the last couple of GB unpartitioned on the drives to get around that problem."
I remember chatting with an admin of a university data centre. He did the same thing because he'd found swapping out a disk in a RAID array caused the same issue even through the replacement drive was the same manufacture, same model number. Once bitten, twice shy.
If you want to set up a company in China, you need a local Chinese backer who gets to hold 51% of the company and its access to its IP. That;s partly, some would say mainly, how China has industrialised and gone high tech so quickly. The choke points appear to be technology, equipment, machinery and materials where no one has set up a local company giving them access to the IP and patents. This means they have to develop it locally. Even with their large numbers of well staffed universities and R&D operations, this still takes time, even when you already know it can be done rather than starting from scratch with blue sky research.
"biometrics are at best a user name, and even that's questionable since you can change your user name but it's much, much harder to change your face and/or fingerprints."
This bears repeating. Again. And again. In 72pt text. With mozilla marquee tags!
"And we're not exactly doing much about China's genocidal policies in Xinjiang either."
To be fair, that's a bit of a sticky problem. What they are doing is atrocious, but they have nuclear missiles and are the "workshop of the world". You only have to look at the "issues" generated by the Russian invasion of Ukraine, ie fuel and food problems for small inkling of what it could be like to sanction China in the same way. China is happy to spend decades, generations, moving towards what it wants. The West works on short term election cycles. The West need to disentangle from China, but it's by necessity a slow process, something the West are poor at.
"watching as the information is being gathered."
That's been possible for quite a few years now, long before Starlink and similar was planned for. IIRC, the first sat phones for civilian use were made available around the end of the 1990's. Military use certainly predates that, probably by a significant margin. ISTR reports of military operations being planned around when satellites could be overhead.
I think it depends on the size of the company. With many layers of manglement between the C suite and the people at the coalface, it gets harder to prove, to a legal standard, what the C suite knew or instigated. There's a current manslaughter case going on locally where the bosses are also the day to day managers and are in the dock over Heath and Safety violations leading to two deaths with a potential prison sentence looming over them.
"This is way more ridiculous than getting humans to the moon via cannon would have sounded in 1865. A better comparison might be trying to do an orbital launch with a battery powered steam rocket in 2021."
As a kid, I used to jam a bicycle tyre valve into the nozzle of a Fairy Liquid bottle, about a 1/3rd full of water then pump up the pressure until it overcame the friction of the jammed in valve and launched into space[1]. The harder I jammed the valve in, the higher it launched (until I jammed it in too hard and the "pressure vessel" ruptured before launch!). Clearly this is a far better and greener launch system since it involves re-use and recycling. It just needs to be scaled up a bit. What could go wrong?
[1]. Space starts where I say it does. In this case, just above the roof line of my childhood home.
"(actually how about real iron core storage? Or stone tablets)"
Funnily enough, that's what I came here to ask when they said "immutable data". I'm not sure spinny disks will survive the launch or landing and SSDs don't really have the lifespan I think they envisage. Although now I'm asking the question, paper tape might well last quite a long time in the cool, airless lava tubes, deep enough to be shielded from radiation. But, as someone mentioned earlier, there's some evidence of meteor impact that might be disadvantageous to long term "immutable" storage of any kind.
Yes, drivers for leading and bleeding edge hardware is forever the bane of FOSS OSs. The OEMs will rarely, if ever provide drivers or information for those wanting to write drivers. Things are improving, slowly, especially in Linux-land, but if you want the latest kit, Windows is the only option.
Must admit, I generally use csh at the command line and only use bash when I need looped command or running scripts. I never noticed that bash had word move left/right with ctrl-arrow keys. But then the first thing I do with a new install is set the key repeat rate to some I find comfortable, which is 3-4 times faster than the default. Likewise, I shorten the delay before key repeat starts. Been doing that since I first discovered FreeBSD 4.3.
Oh, and I've never had an issue with dual or even triple booting. Just always install Windows first because it WILL trash your other OSs :-) Not tried with anything newer than Win7 mind, things might have changed with Windows since then, but the fact FreeBSD uses only one partition and allocates it's slices inside actually makes it much easier and safer to multiboot.
The name's a bit pretentious, but it seems to have mostly worked this time.
It was a a bit disappointing though. Few onboard cameras, much of the process being fed to us as animation. I guess I've grown used to SpaceX giving us live video of the entire flight to orbit. I missed seeing the boosters and first stage landing too. Somehow, despite the futuristic and pretentious name of the capsule, it all felt very retro :-/
Now, I'm off to paddle my rowing boat around the lake. I named it LEVIATHAN!!!
"Given that Russia's access to latest software from big vendors seems quite as restricted as its access to hardware, they may need to revert to older versions which are not as easily subjected to sanctions. Or licencing checks, for that matter."
In the early days of the home computer revolutions, what was available behind the Iron Curtain was knock-off Spectrums and C64 at best, often with low RAM specs. Some very efficient and innovative coding came out of eastern Europe, especially when The Wall came down and access to the latest Western kit became possible.
I can easily imagine a similar situation developing in Russia now, possibly a major shift to Linux if not just outright hacks of Windows so there's no registration or phoning home. It's not like anyone can successfully sue them now.
"I used a Raspberry Pi 4 as a desktop PC for a day when my regular desktop was broken. It was adequate for everything except full screen video, and I suspect the latter was due to the GPU limitations."
Depends what you mean by full screen video. My RasPi4 running Kodi plays 1080p full screen with very low CPU usage. That's X265 video in the main. It depends what codec the video needs and if there is any hardware acceleration in the GPU to support it and software to make use of it.
