Re: It’s toxic and it got nasty during the pandemic

Err, Mr. Eel, you are missing the point so much as to whack yourself in the face with the bat.

The OP's point was that people on twitter who can be "piqued" let's say, by a particular thing, are being deliberately 'piqued' by the algorithm to drive "engagement", so much so that even a completely unrelated-to-anything essentially private conversation will get piled on by warring partisans like flies on shit.

Whatever your thoughts are on COVID are irrelevant - we are discussing Twitter in this thread, NOT COVID. But even in the absence of a feed-optimisation algorithm, you have latched on to this trigger subject, and - consciously or not - attempted to divide the room.

This is the toxcicity of social media in a nutshell - it poisons all rational discussions to turn them into bipolar flame-wars, 'optimising' that poison to the point where Godwin's Law is invoked as fast as possible.

Nvidia RTX 4090: So hot they're melting power cables

Re: Thanks for pointiong out those XA90 connectors, seen em on drones.

Right. And you'd never see a building installation using separately-insulated narrow-gauge wires with low-current connectors in parallel to connect something like an electric cooker or shower.

But "Computer Standards" were written by IBM in the 1980s, and they obviously had some sort of deal going with Molex. They never thought anything would draw more than 1A through the 12V wire (probably only needed for erasing the EEPROM and maybe spinning a disk platter).

(at that time they didn't have "point-of-load" switching regulators on the motherboard itself, so they were more worried about the current on the 5V and 3.3V wires, which are barely used these days)

But for a PC to be "ATX Compatible" it has to use those shitty crimped Molex connectors that were designed in the days before CNC machining was a thing, and only take wire up to 16AWG or so.

Re: Not surprised

Nor am I surprised either..

600W at 12V is.. 50A. And any fule no: Ohm's law says resistive heating goes with the square of current. If you double the current with the same number of pins & same gauge wire, then you quadruple the power (heat) loss in those pins/wires. If you double the current and double the number of pins/wires, then you still double the heat.

Nvidia have doubled their power consumption, but the supply voltage standard is still 12V, so they are doubling the current. But they certainly haven't quadrupled the number of pins. So it's not surprising that they are getting hotter.

On the face of it, those Molex pins are supposed to be rated to 10A - so 12 of them (6 pairs of + and -) naiively ought to be rated to 60A. But in practice if you put multiple pins in parallel then the slightest bit of dust/grease/oxidation can cause most of the current to go through a few pins. Especially since they don't seem to be gold plated.

Plus you have a bundle of cable attached that is, under that kind of load, as much of a heat source as a heat sink..

Maybe they should switch to XT90 connectors for GPUs. That and/or increase the voltage standard.

Or on the other hand we could always, er, stop wrecking the planet and wasting silicon with all this "AI"/VR/Blockchain bollocks and go back to simpler days when GPUs only needed to draw a few thousand polygons at 30fps to run a perfectly good fun 3D video game, and that was all we ever used them for.

Re: Yeah but...

As a Toob customer I can tell you it's worth the wait.

I'm on 900Mbps (link is 1Gbps and it tests at ~930 at speedcheck and fast) for £25/month

It's symmetric, but half-duplex i.e. it's only one fibre that can do 1Gbps up OR 1Gbps down, so probably the missing 70Mbps is spent on link arbitration. This doesn't seem to affect latency though - 3ms ping to 8.8.8.8

Re: Groan….

And there we have yet another false dichotomy between two unattractive options - the tories vs starmer's labour.

I never said I was a Labour supporter, and you are right that this stuff got worse under Blair, Jack Straw and particularly Jacqui Smith (although arguably it started with Michael Howard).

But while Labour were interested in pure state surveillance, it was the tories who handed it to their mates in the corporations (along with everything else.. the railways, the power lines, along with choice cuts of the NHS, education & policing..) So now we are not just spied on "for our own good", we are spied on "for someone else's profit".

Er what? You are trying to say that "Remainers" wanted Hard Brexit? What kind of Remainer wants that?

Although tories are weird. Theresa May called herself a Remainer but was (at the time) the most xenophobic politician I had heard of.. She was behind the "Go Home" vans, the expansion of the Border Farce, and the massive expansion of the surveillance state that was completely at odds with EU law, and she hated the Human Rights act. I couldn't understand why she would declare herself a remainer, and had assumed the only reason she did so is because she actually supported leave but knew that everyone hated her, so the cummings-controlled SPADs told her to declare for remain instead.

Choice between two pre-selected unattractive options seems to be par for the course from the conservative party these days.

Re: "Not -entirely- self-inflicted I think. "

I think your Greedy category deserves an extra subdivision:

There were those "honest" shopkeepers etc that you describe, who thought that they might be in for an extra buck somehow. This category includes British plumbers, builders & other trades that were being out competed by Polish workers, and even the bankers who bought crypto and got ready to short the UK economy might fall in to this category, but they are more likely to fall in to my next one.

My extra category is far more dangerous, these are the political class: The Tory brexiteers, who were greedy for power. Knowing that power is money and money is power, they are quite happy to inflict untold misery on millions if it gives them the levers of power. They are quite happy to push the UK into a full blown economic collapse, towards general strikes, and towards a new world war, because they think they are rich and powerful enough to ride it out.

These are the guys who used to bang on about "sovereignty".. They are distinct from your first group in that they are not expecting an economic renaissance - they wanted to remove the anti-corruption rules (that the UK introduced to the EU!) that prevented them siphoning off all the public assets and handing them to their mates. They want to take over complete control of the UK "take back control.." but the gullible fools think they will be running the UK for the interests of its general population - they won't of course, they will be ruinning it to benefit themselves - and they already are.

When the UK crashes and burns, they will have built their offshore private islands, mansions and manor houses. They could even move to Russia or China, where they might be hailed as heroes who brought down the EU and the UK from inside.

Re: Groan….

Not -entirely- self-inflicted I think. I think a lot of the people who voted brexit were not culpable, in the same way that an imbecile under manipulation by a scheming psychopath is not fully culpable - he has a diminished responsibility.

Propaganda is a powerful tool, and it is becoming ever more powerful thanks to the mass manipulation machine that is social media. It's now extremely easy to manipulate people en-masse, as Cambridge Analytica discovered.

But they even managed to change the rules after the event: It was supposed to be a non-binding vote with the same regime as a general election i.e. there has to be a clear majority to call it a done deal..

If it had been 48/52 the other way, then the brexiteers would have been calling for another vote, and they would have got it. Nigel farage was even asking for another vote when he thought it might not go his way.

But then when the vote was over and the country couldn't have been more undecided if it tried, with a tiny 2% margin in favour of leave, suddenly it's all "we won you lost, get over it remainiac, the people have spoken" etc etc. And Personally I believe that it has been propaganda and foreign trolls that have been driving that.

After all, the person who REALLY benefited from Brexit, was Putin.

Vested interests

No, honestly I think you have your 'vested interests' backwards.

Take a look at https://gridwatch.co.uk/ and you will see that the UK grid is vastly reliant on gas, because there are long periods (weeks or months) where there is scant power from any renewables. Anyone with a clue (including you) knows that batteries are only good for stabilising the grid as a replacement for spinning inertia. They will never have the TWh scale required to provide bulk-storage. If the wind stops blowing, then batteries allow us to prop up the grid for just long enough to fire up a big gas power plant.

Renewables can never replace oil, gas and coal, but nuclear can, and that is why the oil & gas lobby (which is much more powerful than the nuclear lobby) has got it in for nuclear. They love renewables actually, because it allows them to increase their prices as the supply of oil dwindles.

Thus, renewables support Britain's reliance on gas, the price of which is set by a cartel (the OECD) which includes Russia. The vested interests that I worry about are the ones making billions (Aramco alone is making $15 billion a week at the moment!) from burning a finite resource and replacing it with a greenhouse gas.

Biomass is even worse, we are taking something that actively removes CO2 from the planet - trees, chopping them down and burning them to produce more CO2! It's madness. And don;t get me started on CCS. If you are worried about nuclear accidents, a CCS leak can be just as dangerous, if a cloud of heavier-than-air CO2 settles on a town, it will asphyxiate everyone. It has happened before: https://climateinvestigations.org/co2-pipelines-and-carbon-capture-the-satartia-mississippi-accident-investigation/

But again, Drax is an extremely powerful lobbyist, so it gets away with it.

I'm not sure how those economists come up with their figures, but their cost of storage for example, does not scale. It might be right for the current small amount of storage that we can make, but to make it at a scale which could phase out gas, would mean using more copper and lithium than the entire world market.

The same goes for hydro and pumped hydro: We can't make artificial mountains, so the supply of hydro that we have (enough for about an hour of calm weather with no gas), is already about as much as we will ever have (and it is dwindling due to drought) so it doesn't matter how 'cheap' it is if we can't build more. It's a similar story with geothermal, and I am yet to be convinced on the power capability and storm-robustness of wave power.

But nuclear is easy. Change the rules so that it can be built underground, think of it as an artificial geothermal plant!

Re: Bang On - except the death stats

The current water being "dumped" is indeed less radioactive than the ocean itself - that is the obligation set by the regulator.

At the time of the accident, of course there was a detectable pattern of radioactivity coming from the plant, but it was always perfectly safe. In fact I'd argue that Fukushima was a triumph for nuclear safety! It was a very old design, we have improved safety a lot since then, and it suffered what was about the worst thing that could happen to a nuclear reactor: Being hit with an earthquake and tsunami, shutting down its cooling systems and backup generators - (BTW the tsunami itself killed 15,000 people and made 100,000 homeless, you neglect to mention that in all your anti-nuclear ravings eh?) Yet the so-called "nuclear disaster" has killed Nobody! Not even the 50 people who went in to stabilise it expecting to die from the scary radiation.

It's all fear, and it's a fear that is stuffing the coffers of Putin, Saudi Arabia and the big oil and coal companies, by turning people against nuclear.

Exclusion Zone

An exclusion zone is an entirely arbitrary, man-made concept. It is perfectly safe to live there, as demonstrated by the wildlife that have taken up residence and are flourishing in the absence of humans. There are literally birds nesting inside the exploded reactor core at chernobyl, they have been there for decades.

No, they are not mutants, as much as the FUD brigade would have you believe.

The problem with radioactivity is that it is invisible yet incredibly easily detectable down to the most minute level, which makes it scary. Nanoparticulate carbon, benzenes, fluorinated gases etc are all just as carcinogenic if not moreso, but they cannot be detected without a mass-spectrometer, which is a much bigger machine than a geiger-counter, and it has to ingest the material to test it whereas a geiger-counter can see radiation a long way off.

It is the fear of radiation, rather than its inherent danger, that creates exclusion zones.

And it is extremely easy for vested interests like the fossil fuel industry (who BTW are coining hundreds of billions a month thanks to the hole in our energy supply left by early closures, late construction or outright cancellations of nuclear plants) to spread fear about radiation and nuclear power amongst the population.

Re: Bang On - except the death stats

@TheSirFin

This is a great book, presented by a couple of pro-nuclear Greenpeace guys. https://climategamble.net/

In it, they explain how the Linear No Threshold model, used by the regulators for predicting harm caused by low-level radiation exposure, is completely wrong and has no scientific basis. There is no evidence to say that low levels of radiation cause harm, in fact it seems to be more likely the other way round- that low levels of radiation can actually be beneficial. Background radiation has existed the entire time that life has been on earth, after all. Nanopoarticulates and other modern day pollutants, not so much.

But even if radiation were the issue, the fossil fuel industry emits far more of it than the nuclear industry anyway!

Re: Water

Not necessarily the construction companies, but the governments and regulation bodies who set the rules, certainly.

There is a running joke in the nuclear industry that the ONR, NDA, UKAEA, IAEA and AWE are 2/3 staffed by CND fifth-columnists. (and I say the CND is staffed by oil industry fifth-columnists.)

With the rules that come out of those regulators, it's easy to see why people say that: The ONR refuses to set a safe limit on radiation emissions from nuclear plants, knowing full well that physics means that gamma rays can't be completely 100% shielded by any depth of concrete - it sets a wishy-washy principle known as "ALARA" (As Low As Reasonably Achievable") which creates a ratchet-effect of stacking safety factor on top of safety factor, only ending when the project is at the edge of feasibility. (they specifically exclude cost as a factor in deciding whether something is reasonably achievable or not)

They also use a completely daft model (the so-called Linear No-Threshold model) for estimating harm caused by radioactive release to the environment. It assumes that any radioactive material spread over the earth, however diluted it is, is just as likely to kill someone as if it were in concentrated form. That's complete nonsense - all the scientific research says that radiation is only dangerous above a certain threshold (as with sunburn), and below that, DNA in cells is able to repair itself. There's even some evidence to say that this process of DNA repair is beneficial to health. After all, life has always had low doses of radiation in the background.. Modern chemicals and nanoparticulates not so much, but no such extreme regulation applies to other industries which pollute the environment on a horrendous scale. (see this book by two pro-nuclear greenpeace activists: https://climategamble.net/)

As a result, you have utterly daft situations whereby the nuclear operators end up spending billions and making their emissions way below background levels just for someone to come along and suggest a new and very expensive way of reducing them even further, and they are legally obliged to delay their project while they report on whether it is reasonable for them to implement it. Meanwhile the fossil fuel industry emits more radioactive material (though trace amounts of Radon in the billions of tonnes of Oil, Gas and Coal that they burn through each year) than the entire history of Nuclear Fission. Accidents and bombs included!

I used to work for UKAEA at Culham - they once declared a major incident after someone brought in a gas lamp mantle - it was far more radioactive than any of the sources they were allowed to use.. Their sensors would register a spike if you went too close with a bag of Brazil nuts.

According to the dosimiter badges, the staff on site who receive the highest ionising radiation doses are those who work on the security gate, because they catch more cosmic rays than those inside the building.. If you accidentally bring your dosimiter badge with you when you go on a long-haul flight, it will be picked up by Health Physics and you may not be allowed on site because you have exceeded your radiation dose.. Cabin crew receive thousands of times higher doses than nuclear workers are permitted to take. It's utter madness. That is why nuclear is so expensive, the regulations are stacked against it.

That's also one of several reasons why it's so much cheaper and quicker to implement in China...

Water

Yeah I came here to say that. The water in the primary circuit of a water cooled reactor is a closed loop, it is never used up. You wouldn't want water that has had direct contact with the core going -anywhere-, obviously!

TFA is extremely misleading on the water argument, so much so that some anti-nuclear types could use it to complain about false benefits.

The benefits of molten salt reactors are not about water use (you would site them on the coast like any other reactor) the main benefits of MSRs are, THEY EAT NUCLEAR BOMBS, and THEY EAT NUCLEAR WASTE. Most normal nuclear reactors consume about 3% of their fuel before it is considered 'spent', whereas MSRs can reach 50%, i.e. more than 10 times more efficient use of the fuel. They consume nuclear waste from other reactors and ageing weapons stockpiles, as fuel - you basically dissolve the warhead in the salt, and its energy is burnt off slowly and safely over decades.

We have enough spent fuel rods, plutonium stockpiles, and 'dud' warheads to power the world for centuries, we would never need to mine or enrich new uranium again, or at least that's the idea.

However, I am sure that the anti-nuclear lobby, which I am convinced is funded by the sorts of companies that made 3 billion a month recently in the UK, will once again step in to ensure that the world chokes on CO2 from coal, oil, gas, and tree-burning..
