"

A nuclear power station is really just an enormously complex steam engine ... with much more dangerous waste products.

"

Wrong. The waste products of nuclear power stations are a darn sight safer and more easily managed than the waste products of coal-fired power stations.

Re: Thorium Cycle Reactors

All nuclear reactor designs are absolutely amazing. All of them will produce astonishing power outputs cheaply and cleanly with virtually no problems, until they are built.

The same is far more true of so-called "renewable" energy sources.

Re: Interesting idea

Very true. But it's also massively more flexible and extensible. Need more leccy? Add a few panels or an extra turbine of some sort. Or spend £30+ billion and wait 20 years for a new nuclear station

"

All well and good if you have both the money and roof space to add a few more panels, and are prepared to severely ration your consumption over the UK Winter (just when more electricity is needed). But it's probably less than 20% of the population who would even be able to do it, let alone those who would find it desirable.

But if you think it's so great, I am prepared to try it. I'll let you convince my landlord and the owner of the block of flats I live in to allow you to put PVs on the roof, and you can then pay to install them. In return you can have all the money I'll save from having them in perpetuity. Good deal? While you're at it, you can swap my petrol car for an EV and negotiate with my council to install a recharging point somewhere I am guaranteed to be able to park overnight. Again, you get to keep all the money I'll save (less the amount I have to spend on the occasional journey that's as yet impractical to do in an EV).

Re: Interesting idea

"

There are a surprising number of people on this thread who seem to be resiting any and all change and clinging to the large infrastructure.

"

Maybe it's because we have done the arithmetic and plugged in some real-world figures. And discovered that for the vast majority of people it simply does not compute either from a practical viewpoint or a cost viewpoint.

Come up with realistic figures for (a) how many MWh the average household with an electric car would need per year and (b) how many MWh the average roof full of PVs will generate in the UK (at its half-life point). Then give a realistic estimate of the cost of the installation and its expected lifetime.

Then see how realistic and cost-effective your "solution" is. And that's without taking into account the vast proportion of flat-dwellers who have no roof and/or cannot park their car close enough to charge from the home, or do not have a roof suitable for efficient PV installation.

It's similar to the notion that we should all grow our own vegetables. All great when you are hand-waving, but not so great when you go into the details of carrying it out.

Re: Interesting idea

"

Another difference is that climatology is a science, where evidence makes or breaks theories.

"

Really? Such as the evidence that not a single climate model has correctly predicted anything at all, or the evidence that the historical temperature figures were shown to have been altered to support the theories?

If what science had predicted 15 years ago had been correct, the chair I'm sitting in would be 5m under water by now.

Yes, there is climate change (always has been, always will be). How much man's activities have contributed (if any) is still conjecture rather than science. But in any case it's beside the point. There is no way that Man will change our activities sufficiently to make a gnat's prick worth of difference, so we would be far better off planning how to live with the consequences than coming up with expensive schemes in a vain attempt to prevent the inevitable. And not everything to do with climate change is going to be detrimental by a long chalk - much will be an advantage.

Re: Interesting idea

I thought I'd point out, though, that if one builds a nuclear power station out of concrete (what else?), it isn't zero carbon.

"

Pretty much any form of generating station requires concrete (or equivalent) in its build. A nuclear station may need a bit more than a gas-fired station, but I should think the difference is trivial compared to the saving over the life of the station.

Re: Interesting idea

"

We need to stop thinking big infrastructure and start thinking small and scalable. In IT speak, let's start scaling out instead of scaling up because it's almost always easier and cheaper.

"

Huh? Small-scale production is less efficient and more expensive than mass-production in just about everything, and energy production is no exception. Individual wind and solar power sounds all very nice until you do the arithmetic and realize that it is an expensive way of generating insufficient power (apart from artificial government=taxpayer subsidies). You'll also find that you cannot build your own car, make your own clothes or grow your own vegetables any cheaper (or greener) than buying the mass-produced stuff. It might make you feel all green and self-sufficient, but that's just a foolish illusion. All you really get is a bit of self-satisfaction from the DIY.

Privacy, security fears about ID cards? UK.gov's digital bod has one simple solution: 'Get over it'

Cynic_999

Re: @ toilet duk

"

My suggestion: if you're required to obtain one, do so and simply leave it at home in your drawer unless you're required by law to carry one at all times or unless life is deliberately made so difficult that carrying an ID card makes things incredibly easier.

"

It will be the latter. If everyone is required to have an ID card, then inevitably more and more services will require you to present it ("To improve your user experience"). Pretty quickly it will be needed to enter a train station, to buy prescription medicines, phones, booze or other age-restricted items. Slowly the requirement to present your ID card will widen, until so many everyday activities will require it to be presented that you will be forced to carry it. That's assuming that it does not become an offence to not have it to hand when the nice police officer demands to see it.

Re: @eDog - why should the taxpayers be on the hook?

"

IMHO police officers should be required to carry liability insurance, for when they do something like shooting an unarmed black man whose family sues for a few million dollars.

"

No - that would end up costing the taxpayer even more. The insurance companies will obviously set the premiums so that they still make a profit (across the whole country), and so the taxpayer will be paying not only for the pay-outs of the lawsuits but for the yachts and private jets of the directors of the insurance company as well.

Insurance for an individual makes sense (risk is distributed across all the policy holders). But insurance makes no sense whatsoever if you are a very large national entity because it is bound to cost more.

It's all a matter of time: Super-chill atomic clock could sniff gravitational waves, dark matter

Cynic_999
Silver badge

So how do you compare them?

So you have two different clocks separated by a large distance. I can see how you can measure a constant difference in time-keeping as the error would get bigger & bigger. But if a gravity wave goes past and one clock *momentarily* speeds up or slows down relative to the other, how do you compare the instantaneous time readings of 2 clocks separated by a large distance? The data from the clock to the distant observer cannot travel faster than the speed of light (which is not a constant in different mediums, and possibly is affected by gravity itself).

OK Google, why was your web traffic hijacked and routed through China, Russia today?

Cynic_999
Silver badge

"

So basically people are complaining that traffic destined for Google may be stored, analysed and used for nefarious purposes by someone other than Google?

"

Ignorant people may be complaining about that, but that was not what happened. The only significant traffic that was mis-routed would have been SYN (connect) attempts, which went unanswered. Whatever request or data the person trying to contact Google may have intended to send would thus have not been sent. To anywhere. So the only data that would have been obtained was the fact that a connection request was made to Google from a particular IP address at a particular time for an unknown purpose - hardly something that is likely to be of any concern.

Possibly there was a bit of UDP data that got through (UDP does not require a connection be established before sending the payload - often used for live streaming video or audio for example), but in almost all cases there would be some sort of 2-way handshake before streaming the data over a UDP connection, so really no risk that Internet calls were being intercepted.

Why the outrage?

Both UK and US have been re-routing Internet traffic for decades in order to spy on their citizens, so it's a bit hypocritical to get all upset when someone else follows suit. (There is no technical reason for your Internet data to get routed to Menwith Hill).

In any case, if this was really deliberate (and it may well not have been), then it was simply a denial of service attack rather than a spying mission because it stopped any TCP connection being made, and no data is sent unless and until the TCP handshake has completed. Had there been servers in Russia, China or Nigeria accepting the connection requests and pretending to be Google, then it would have been far more sinister.

"... even if, as is routine these days, he will serve a maximum of half that time behind bars.

"

The word "routine" makes it appear to be something that is optional, and "these days" makes it sound as if it's a recent thing. Neither is true - sentences have comprised a certain proportion to be spent in prison and the rest out on licence for many decades (though the exact proportions have changed from time to time). The media always makes out that release from prison before the entire sentence is served is some sort of discretionary concession. It isn't, it follows mandatory rules of which the sentencing judge is well aware.

UK.gov fishes for likes as it prepares to go solo on digital sales tax

Cynic_999
Silver badge

Re: Too complicated

"That won't help tax companies that do sell stuff, or enable selling of stuff. eg. Amazon, Ebay."

The government gets sales tax from online retailers, which is effectively 20% of UK based *turnover*. Just how much more do you think the government ought to get? To my mind, 20% profit on all sales while doing fuck-all to either facilitate or earn it is far more than enough.

Maybe stop to think that maybe it is the huge amount of tax that UK citizens pay directly or indirectly that is causing recession and the lowering of our standard of living. At least 80% of what you earn is currently taken by the government in one way or another (just do a bit of arithmetic), and it's over 90% for many people.

Now while I understand that we need to pay the government to provide general infrastructures and services, I do not accept that the government is providing anything close to 80% of the needs of the average citizen. Just a few rough calculations make me pretty certain that the majority of our tax money must be disappearing into quite a few "black holes" and is *not* being used to benefit us (the ordinary citizen) in any way whatsoever.

Probably it's to eliminate C&C

One of the weak points of drones has always been the command & control link. Ground signals can not only be jammed, but the signal from drone to ground gives away its position. Hence why satellites are usually used for the link. But if the stakes are high enough to interest the big players, the satellite down-link gives away which satellite is providing it, and satellites, having no defences or any way to hide, can easily be shot down by nations with the technology to do so.

I suspect that the only reason that military satellites are not usually targeted is some sort of agreement between the major powers of, "We'll leave yours alone if you leave ours alone." Which would change if drones do enough damage to such nations.

But an "A.I." drone needs no C&C link. In reality the "A.I." instructions might be simply, "Blow up anything that moves within a designated area unless it is displaying the (secret) 'friend' symbol or signal.

Samsung 'reveals' what looks like a tablet that folds into a phone, but otherwise we're quite literally left in the dark

Cynic_999

Alternative

I bought a phone-sized projector containing WiFi, Bluetooth and an Android OS and was very impressed - pretty cheap as well. It's perfect for occasions when you need to look at a reasonable size image on a very portable device. The LED projection is bright enough to see in shaded daylight up to about A3 size, and in a dark room will project very watchable movies on a wall or screen several metres in size. Battery charge lasts over 2 hours of continuous projector use.

So my idea would be a phone with a normal size display, but with a projector lens on the edge for when you need to see some reasonable detail or display something to a group of people.

True only of the individual user's download speed (which was what was being measured). If you have 100 people all streaming movies, the total bandwidth needs to be the same as if they were all downloading the movie before playing it. Jitter & lag don't matter on a download, and can be compensated on a stream by having a large buffer (e.g. the movie starts playing after a few minute delay to get a decent amount buffered).

Probably never. Any bug that results in a buffer overflow or similar is tagged as being a possible path to malicious code execution. In practice however, it is one thing to get your binary into a (usually unknown address of) RAM, but another thing entirely to get the CPU to actually execute it. And yet another thing again to get the code to do anything more serious than crashing the system.

Outsourcing

When people cannot get any legitimate income, they will automatically turn to less conventional methods. Therefore the government policy is effectively outsourcing the benefits system to organized crime which will be only too happy to step in and fill the gap. Instead of the tax-payer funding the lifestyle of single parents, their kids will now be able to do their bit via various self-funding initiatives that will also help their community by filling vital gaps in the sex and recreational drug supply areas. Also helping to narrow the gap between rich and poor via various wealth redistribution schemes aka "Faganism". Which is also excellent vocational training which will help the teacher shortage by cutting down on the number of pupils attending classes. A win-win all round.

Forgotten that Chinese spy chip story? We haven't – it's still wrong, Super Micro tells SEC

Cynic_999

Too complex to be true

I stated in the comments to the earlier article - if you have the resources to make a custom chip, then you would create a lookalike of a suitable chip that is *already used* on the MB, and substitute the bogus chip for the real one anywhere along the supply chain to the MB manufacturer. No board modifications needed, and nobody associated with the server manufacture will know a thing. The bogus chip would work correctly, but have extra functionality. Then there would be no outward difference in the motherboard and it could only be discovered by observing the unauthorised behaviour. Not even examination of the silicon would make it immediately apparent, because the bogus silicon could be marked with the correct chip ID and a bogus "new revision" number.

Extraordinary claims require extraordinary proof. Embedding a chip in a PCB would require a completely new PCB fabrication process so is inherently unlikely (Everyone working in the PCB fab would have noticed all the new machinery and a complete change to the process flow). Unless the news agency can produce a PCB modified in the way claimed, I do not believe a word of it.

The mirror would be focussed to an angle of far less than 1 degree, designed to illuminate only a tiny fraction of the Earth's surface (so requiring many orders of magnitude less light than the Moon to do so).

Comparison with a telescope mirror is comparing apples to elephants. Telescope mirrors must be rigid to keep a precise shape, and so are thick & heavy. An illuminating mirror would not need to hold a precise shape, and would be made of extremely thin and light flexible sheets that are unfurled when in position.

Re: Eight times brighter than the Moon?

"and there's no way this could come anywhere near the amount of light you get from a full Moon."

Of course it can, and the article states that it will be 8 times brighter. The Moon is not only much further away, but most of the light it reflects does not hit the Earth. The mirror would focus 100% of the light it reflects onto a tiny fraction of the Earth's surface. (In fact the Moon, being convex, is exactly the *wrong* shape for an efficient light-mirror).

Re: Drag

"So what happens to that radiation pressure? In order for the satellite to remain in its orbit, something has to counteract it. "

Not necessarily. It could be arranged that the pressure during one half of the orbit is exactly the same but opposite direction to the pressure in the other half of the orbit. In fact, adjusting the mirror "sails" during China's daylight period could be used to adjust the satellite's orbit, thus reducing or eliminating the need for it to have any orbital engines.
