Your forget that you don't just "shut down" a nuclear reactor, it takes at least 3 days to moderate to a temperature where the loss of control or coolant doesn't lead to a criticality crisis. And that's at full pump flow; if the coolant system isn't 100% operational it will take even longer.
The Russians took a HUGE risk in attacking an active nuclear reactor.
Consensus of reporting suggests that all but one reactors are shut down, the one that is still operating is to maintain the critical systems. No attack on a nuclear reactor has been reported. Light shelling on a training facility on a nuclear
site has been reported.
Any reports have to be considered in light of censoring and filtering.
Putin hoped to explode the reactor and spread its contents across Europe. The wind was heading towards Romania, Poland, Germany and Netherlands. NATO would do nothing, clearly, and he would establish that he can attack Europe with 'near'-nuclear weapons without any response from NATO.
Did he really? I’m impressed with your insight into Putin’s strategy. Do you have an inside contact in the invasion planning command? Or do you read tabloids and Faecebook?
You’d think they could do a bit better than a bit of light shellling on one of the training school buildings if they wanted to release nuclear pollution.
The earth-moon tidal effect is pushing the moon further away from earth so it’s not coming down, probably this and other accretions make it go away faster. The result is to make earth days longer as we spin slower.
But on the scale of human lifespans, or even human existence a tiny tiny negligible amount.
"Exaggerating? Shelling a nuclear power plant is a very frightening thing. It isn't exaggeration to call it out, or to highlight how dangerous it is."
This power plant is massive, enormous sprawling campus. It would be possible to shell within its limits and be nowhere near the critical areas. I'm sure that the Russians had a hand in building it and would know a thing or two about it. All of its fuel is supplied by Russian companies too.
It's true if Sipeed have gone with the unratified AllWinner D1 (on their Nezha SBC) which is nowhere near as powerful as the ARM on a Pi4, and can't sell it for less than £87 direct from China (or £140 all taxes paid on Amazon UK) then obviously the economics aren't there yet.
Pi5 will be ARM just like all the other back-compatible Pis.
The shocking truth about the "Motorsports triangle", which goes between Woking in Surrey, to Milton Keynes and across west into Oxfordshire is so successful in motor racing because in the UK we train engineers in universities then turn them out into a nation that barely any aero or motor industry left. So they are engaged in motor sports.
Yes, I started with Demon in the 90s. It was them or the more expensive pipex. I had the US Robotics modem and I plugged it in and followed the instruction for ftp to "you are now connected to a computer in the USA" which I think was in Virgina,.
I remember that moment, I had trouble believing it.
Then into their little ASCII text based UI to usenet and pop email, never looked back.They did eventually become a victim of their own success and became too slow to use.
I think the other chap, Chris Goodall survived the LAdbroke Grove rail crash.
Why says RT is forbidden? It’s on my TV, channel 113, one of the HD Freeview broadcast channels. I don’t get Fox News on Freeview, or any broadcast as far as I know,
It’s actually a laugh spotting the continuity errors and mistakes in their propaganda films.
I think we can easily draw a distinction between a media outlet that allows commentary on its content which is presented under its editorially approved policies, and a social media company where anybody can contribute any content they like and decide their own levels of privacy.
For example, I can’t just post a picture of my food and a story about my visit to Wagamama on The Register and then decide which other commentards to follow whilst controlling which ones are allowed to see it. The primary content is under control of the editors. So this, “ahh but you are posting on here so you do use social media” is twattish.

This is an early experiment by the LibreOffice people where I'm sure they haven't rewritten their huge codebase for optimal WebAssembly, but have lifted and shifted the existing code in, with adaptations here and there. Of course it's going to be slow, it's not supposed to be a new ready to go productivity tool. WebAssemby itself is still a work in progress. They are just experimenting.
Ridiculous expectations.
If I code something using rust, specifically for WebAssembly, keeping the bulk of the work inside the process without too much handing over to JS, then it's nothing like "grossly inefficient". It's by far the most efficient way to do it in a browser.The ratio of actual webassembly code to JS code is irrelevant, it's the amount that each of those is called into use that matters.
As as already been explained, WASM currently relies on JS for DOM interaction and has a clunky method to hand over in memory pigeon holes. When this is addressed that bottleneck will be reduced.
The problem as I see it is that people can’t get less. I have the option of gigabit, but paying more for it would give me precisely nothing useful over the 110 mb/s I have now. I have 110 because it’s the entry level, I don’t need it. They won’t offer me a better deal, which would be 40 mb/s for half the price. I have to take all this unused pointless capacity.
I work from home with multiple remote desktops, while other people in the house stream video, gets nowhere near 40 mb/s.
Like having a 60cm diameter pipe to supply water to my home. Absolutely no need. So all this bragging or worrying about broadband speeds is idiotic, go and worry about something important.
The charity Raspberry Pi Foundation don’t develop these products, the Foundation are there to promote education.
The SBCs and accessories are pretty good, considering they trailblazed the low cost thing. Enough money has to be spent on compliance already. The occasional oversight is forgivable.
This “parents should do their job” crap betrays massive levels of arrogant, smug ignorance. Absolutely clueless about the real world. Thick as shit.
Our school lost two kids to suicide, and I’m now heavily involved in trying to find ways to catch this stuff before it gets to that stage. The parents mostly are trying all they can, but the circumstance are not all comfortable little happy families and they are usually not to blame, It’s massively painful to me to see this stuff.
btw, social media is often involved.
