Re: Just as far away as before

To be honest, quite a lot of what might be classed as intelligence in humans can be revealed as simply generalised ape behaviour, if you know a little about the behaviour of other great apes such as gorillas and chimps (it is a mistake to study chimps exclusively, because they too have diverged quite markedly from our common ancestor and don't quite behave like a general purpose ape might).

A lot of brain power goes on keeping the supporting systems going, and this is pretty much hard-coded and adapted to the particular body that the brain is a part of. This isn't intelligence, however; our breathing response and mammalian diving response might be compared in an AI to the power systems being able to switch from general line power to UPS, and once on UPS to be able to fire up the auxiliary generator.

Humans actually are fairly parsimonious with their general intelligence. You rarely see humans turning on full intellectual power simply because most of the time it isn't needed; most of the time we humans cruise along on various autopilot systems. So it is going to be with AI systems; most of the time you'll only see limited responses since full-on AI shouldn't really be needed.

European Court of Human Rights declares backdoored encryption is illegal

Dr Dan Holdsworth
FAIL

The goal of monitoring everyone is apparently so attractive to the American government that they have huge data warehouses that store harvested encrypted comms in the rather vain hope that at some point in the near-enough-to-be-useful future they will happen upon a magical encryption decryption tool that will enable them to break these communications and do something useful with the data.

In the mean time, it isn't their money that they are wasting, but merely that of the American citizenry so they continue to store petabytes of useless garbage.

All in all, this is basically really rather silly. Most criminal enterprises require the participants to actually do something, whether this be sell small packets of dubious powder or wave guns at bank clerks and so on. Modern interception can tell who is talking to whom for the most part (criminals have yet to be brave enough to encrypt their messaging and stick it on Usenet for all to see, but not see who it is intended for) and thus knowing that at least a few in a network are known wrong 'uns would lead one to the strong suspicion that the entire network is mostly criminal and all members ought to be briefly scrutinised.

Of course this does fall flat if a few bank robbers are also part of an internet knitting club and are covertly exchanging patterns, but then that's what policing is supposed to sort out.

Re: Throw me in that briar patch!

Yeah, we've had this one a fair number of times where I work, and HR have had it explained in painstaking detail as well.

Specifically, engineering jobs attract people who are good at engineering. Quite a few of these are either actually autistic or have a lot of autistic traits, chiefly those of not actually liking people very much and certainly not being very good at dealing with them. So, taking oldish, experienced engineers and trying to turn such individuals into managers is basically the psychological equivalent of square peg, round hole.

It doesn't work and when engineers are forced to try to become managers then you get really crap managers and also lose good engineers.

This sort of thing is why I opted in the end for an interview with a private psychiatrist to work out once and for all if I was autistic; I am and have NHS-accepted proof thereof.

Re: It's everywhere

Actually there are several ways of looking for pollution, depending on what you're actually interested in.

If you want really clean chalk streams, then you want to reduce phosphate levels to a bare minimum along with nitrate and pretty much everything else, which is all very well but actually quite difficult to do since it doesn't take much extra phosphate to get plant growth going.

If on the other hand you're looking for grosser levels of pollution, then nitrate is one way to go but this too will mostly detect agricultural run-off. The indicator for sewage run-off is to look for faecal coliform bacteria, which are the really, really common bacteria that all mammals excrete from their guts. These are very common hence easier to find than the much rarer but more damaging actual pathogens.

light monorail?

To be honest, I'd say that light elevated monorail is a much better bet if you want fairly quick, fairly easily installed light transport between cities.

A monorail solves quite a few of the way leave problems because it is elevated above the ground, and if constructed of decent materials then the pylons and track can be made to be fairly unobtrusive. The carriages suspended from the monorail need not be particularly large, obtrusive or noisy either since they can use solid rubber-composite wheels instead of steel, which reduces rail wear and noise. Power isn't now an issue either; you simply run the vehicles from onboard batteries, with a pair of recharge rails set every so often along the length of the tracks.

Power and rails normally cause problems, but not if these are five metres off the ground as these would be.

The only thing that light monorail cannot do is shift heavy loads very well, or shift loads at extreme speeds. However in a city speeds would be limited to about 20 mph, and to 50 or so out of cities. Doesn't sound much, but that's better than a lot of motorways these days and the infrastructure is much, much less obtrusive.

Re: It is only Covid if you take a test

And so we come back to heat recovery ventilation once more.

Take one well-insulated building that is also well sealed. Put some humans in it. Watch as the exhaled moist air causes the humidity to rise rapidly and the fungal spores start to germinate.

Heat recovery ventilation is the answer. You use a little bit of power to push outside air into the building over a heat exchanger and to pull inside air out, again over a heat exchanger. The result is lots of lovely warm outside air in your building and no fungus problems to speak of.

Re: It is only Covid if you take a test

COVID-19 is not a common cold.

The major difference is that covid uses the angiotensin-2 enzyme/receptor to get into cells, and in doing so it can interfere with this sub-system. Angiotensin regulates blood pressure and wound healing; if lots of angiotensin-2 (ACE-2) receptors get clogged up with virus then your body interprets the sudden superabundance of angiotensin-2 hormone as news that something's very wrong.

Specifically, lots of angiotensin-2 hormone means that blood pressure is low and there is a wound somewhere. This makes your body alter blood chemistry to make the blood extra-sticky and much more likely to clot, and activates the smooth muscle in your arteries to try to seal off any holes. There's no feedback loop here either; as long as angiotensin-2 levels are high, your blood remains set to clot at the slightest provocation.

That system is what caused deaths from covid-19. Super-sticky blood clotted everywhere, bunged up lung function and even brain function. That's what the vaccines were aimed at: not entirely stopping the disease but merely stopping it going systemic and hospitalising the patient.

New cars bought in the UK must be zero emission by 2035 – it's the law

Dr Dan Holdsworth

Re: Think of the Grid! - running costs are a thing.

The basic problem really is that governments have grown used to fuel duty as a revenue source, and a way of demonstrating their fitness to rule. Admittedly this boils down to "We are great leaders because we won't crap on you more than we are doing already", but the effect is the same.

The problem is how you replace fuel duty when electric cars can be recharged from household or other electrical sources and where some of these sources can be solar, hydro or other non-grid electricity. Pretty much every solution that tries to put a levy on car charging comes up against "User has control of hardware and can/will circumvent control systems".

Road pricing is another control freak wet dream: it requires that you monitor where vehicles go in order to charge them at those times, and will also allow for automatic issuing of speeding tickets and so on. Once again, the problem is that the end user has control of the hardware and a huge incentive to circumvent the charging system. Various activist groups would also find such a system to be a gold mine for their uses, since spoofing the system into fining drivers unjustly rapidly creates a groundswell of discontent against the government; this is always the hardest part of any campaign of political action (even terrorism) but if you can get your intended target to behave unjustly towards your target audience, you've got it made in publicity terms.

That a government would give up most road pricing and simply use Zero Emission Vehicles as a public good will likely have occurred to nobody.

It's ba-ack... UK watchdog publishes age verification proposals

Dr Dan Holdsworth
WTF?

What everyone seems to forget is that porn these days doesn't actually make much money. There are lots of free sites out there so advertising revenue from users who are by the very nature of the product not going want to click on adverts is the only way to go. Porn sites get hosted wherever the hosting is cheapest and law enforcement is least onerous, therefore this means very few are UK-hosted.

So, if you have a country that's trying to make you jump through all manner of hoops when their citizens try to access your site, what do you do?

1) Do nothing and hope they don't notice you

2) If contacted stick an "Are you 18?" banner on your page.

3) If threatened again with credible legal action simply black hole all UK IP addresses with geo-IP and a firewall; if they want to look they can use a VPN.

You will note that trying to force credible age checking on the users doesn't occur on the list. That's because this costs money and porn simply doesn't pay enough for this to be worth doing.

How to teach people the wrong thing

So, a free product is now to be ring-fenced with all manner of restrictions but also the government has to leave VPNs completely untouched.

It therefore will take one or two tech-savvy teens about five minutes to work out that a free Chinese VPN that terminates in somewhere not-UK is a completely effective way around this block. Granted such a thing is a data-stealing nightmare that likely also tries to infect everything it touches with viruses, but the average teen male won't see or care about that at all.

What IS being taught to young, impressionable teens is a very simple message: The Government is really thick. Like, quite incredibly, knuckle-draggingly stupid and all that matters here is not being caught. So, if you combine this with drugs policy then the message is quite simple and straightforwards:

Do whatever you like as long as you don't get caught.

Steam sets off smoke detectors just fine. How do I know this?

Many years ago I was living in what amounted to a hall of residence for Rothamsted Research Station; the old Rothamsted Manor house. This was an old and rambling house that was mainly wooden and was essentially one great big fire trap; if the alarm went off you got out fast.

Anyway, some muppet had decided that the best place for a smoke detector was next to a bathroom with two showers in it. Not just any shower design, but thermostatic showers that were always that little bit too hot, so you always ran them full on to try overload the hot water input and cool the shower a bit. Given how hard the water in that area is, pumped straight from chalk aquifers, thermostatic valves vary between being cleaned of limescale and being in need of cleaning; these were a silly idea.

Anyway, one day I was in these showers, bathroom window closed because it was brass monkeys outside, and the inevitable happened: steam set off fire alarm, alarm went off, I got out, dryish and dressed in record time and thereafter was straight into "Baldrick, deny everything!" mode, convincing nobody at all but proof was not really available.

The ultimate cause of the Chernobyl accident was similar to this. The reactor design was one which, if you put in fuel rods containing depleted uranium, could be used to make plutonium. Plutonium is military stuff that goes bang, therefore methods of making it are secret and everything around secret stuff has to be secret, or so goes military doctrine.

One of the things that was made secret was an annoying little misfeature of the reactor design. The core was graphite and graphite expands when hot. The control rods were engineering fit rods, and as such tended to stick a little when the reactor core was hot and had expanded a little, thus making the fit a little bit tighter. To solve this, the first eight inches or so of each control rod was graphite, which as well as a nuclear moderator is also a good lubricant.

The problem with all of this was simple: graphite is a moderator; stick graphite into what was an empty hole and the reactor initially starts to run even better than before, until the rest of the rod descends into place and the cadmium starts absorbing neutrons and shutting down the nuclear reaction.

Standard "Oh golly, shutdown" procedure with a nuclear reactor is to drop control rods into it as fast as possible, even all at once to shut down the chain reaction FAST. Do that with this sort of reactor and you suddenly make it run a lot lot better which makes the core hotter which jams the control rods at that point, and shortly afterwards the whole thing goes seriously bang.

Correct shutdown procedure here is firstly keep all coolant systems running full belt, and secondly insert rods quickly but sequentially. You don't shutdown the reaction quite as fast, but you do live to tell the tale.

All because that little foible was a military secret that the civilian plant operators weren't cleared to know.

Re: power

The post-human civilisation that is running the sim is probably living in a utopia of some description, which whilst being optimal for living in is also really rather boring. Mind-numbingly tedious, in fact. So, to maintain interest in being alive, sims like the one we are in are run so that these utopians can once again live in a risky, exciting sort of world.

Of course, whilst we die they simply do the utopian equivalent of sticking another 50p into the arcade machine if or when they croak it, to have another go.

The sim is of course going to be heavily and fairly cheaply optimised, which explains a lot of paranormal phenomena quite nicely.

Past-life memories, for instance. This is the sim recycling the code needed to run a human mind and specifically the link to a utopian mind; this is probably quite difficult to do from scratch so the sim will recycle as much as possible and take as many shortcuts as it can, including not filtering information flows. This will lead to info from one simulated human life leaking back down the link to another human life from the utopian in his bedroom remembering one life after it has ended.

UFOs: glitching aircraft object code. Poltergeists: glitching object movement code and probably something that is going to be fixed properly in the next major release. Similarly ghosts of all manner of stuff; simply memory garbage collection not running as well as it should run.

So, try not to look for and poke the holes in reality, because it isn't at all well built and you might just cause the whole kaboodle to dump core and end.

Re: GridWatch

We need, in other words, a lot of small but long-lived nuclear generators that might as well use district heating as the cold side of the heat engine. If we can operate the hot side at a sufficiently high temperature then we can use the waste steam from the turbines as steam input into district heating systems to supply heat to domestic consumers. We could also use grid-scale heat pumps to concentrate industrial waste heat such that it can be redistributed into district heating systems.

This sort of approach is only going to work in towns. Countryside locations are likely going to be burning biomass to keep warm for a long time to come. Contrary to popular belief, cycling carbon around the carbon cycle is an essentially harmless activity; it is inputs of fossil carbon into the carbon cycle that are causing the problems.

Re: For many of us, hybrids make more sense than BEVs

The problem with road pricing is that the "obvious solution" namely a location sensor in the car is a very bad idea indeed on several fronts.

Re: Not sure I understand this.

It is quite possible to mandate breakable encryption. All that happens is that people layer in non-breakable encryption and "encrypt" the already-crypted message with the broken Government rubbish. This doesn't even need to be electronic in nature; a random one-time pad hand-written using a top copy and a literal carbon paper copy underneath would allow two individuals to communicate entirely securely even with known-broken Government encryption.

Moreover, if you know the Government encryption is broken, you simply do not use it. Instead you post your crypt-text onto public forums like Usenet News; everyone can see it but only the recipient can decrypt it.

BMW found that one out the hard way.

Lexus vehicles thus all have heated seats since it is a lot easier for the manufacturer just to say to a supplier "Give me X many front seats to usual spec" than to have several different specs.

BMW however thought they could play things a little differently: make drivers pay monthly rents to "unlock" features in cars.

To say the customers were displeased was an understatement; retro-fit activation kits became rife and the bad publicity hit the maker very hard indeed.

Re: Care?

Proclaiming something to be "Settled science" also sounds suspiciously like someone trying to shut down debate on a contentious issue.

It should be noted that Darwinian evolution is not regarded as "settled science" by biologists. Instead, the debate is still open and very interesting things like inheritance of gene promoter levels and other rapidly-changing evolutionary things have been noted. Not Lamarckianism per se, but getting quite close to information transmission from generation to generation. Oh, and then you have the interesting embryo nested in embryo thing that asexually-reproducing aphids do, so the adult mother influences whether her grand-daughters have wings or not.

By keeping a subject open and not settled, research is furthered and science benefits; shut the debate down and eventually everyone starts seeing cover=ups even when there aren't any.

Budget satellite drag sail shows space junk how to gracefully exit orbit

Dr Dan Holdsworth

Re: Who's doing the evil research?

The point of the exercise is to create surface area which interacts with the extremely tenuous atmosphere still present at those heights. So, why not use a large amount of fine, metal-coated filament which will become statically charged as it deploys, together with small leaf-like bits of membrane which similarly become statically charged and end up sticking out in all directions. What you end up with is a huge, leafy cloud of fluff, which whilst it hasn't got the elegance and surface area of a sail is still a huge increase in surface area.

Attached to any satellite this will (at least at orbital heights) increase drag and help de-orbit the satellite; it should also be light enough that the thing breaking up should be a problem.

Re: Not holding my breath

Not so much defective as flawed by design.

Remember back when diesel was the flavour of the month and everyone was supposed to buy a diesel? Well, the taxi and minicab firms listened to this, and bought diesels. They then found that the diesel filters in the exhausts were prone to getting blocked if driven a lot in cities, in stop-start traffic. The taxi drivers then hit on a cunning solution: remove the DPFs entirely and rely on the fact that a well-serviced and thoroughly warmed-up diesel engine will pass the smoke test with flying colours even without a DPF.

These are the "defective" vehicles that are being targeted.

In truth, it is perfectly possible to make a DPF which can cope with being run like a taxi; it is more complex and more expensive and needs a supply of electrical power to heat it up to burn off the soot, but you can have a clean, green diesel taxi; you can even have one that's clean, green and doesn't chuck out nitrous oxides provided you set up the engine management system to use enough adblue solution to actually solve the problem, as opposed to just enough to pass the tests.

The only problem is that diesels that pass the emissions tests in real life cost a good deal more than ones which passed the old, rigged, EU standards.

As long as you design the file so that the medical person has view of the notes, the drugs being taken and the flagged conditions on the page then you should be doing reasonably well. If you add to this a database of known drug interactions and known allergies that each patient has, and you allow the main system to add in hints that an allergy to antibiotic A might mean that the patient will be also allergic to closely related antibiotic B, then you also have a useful system.

Similarly, if you have in the notes details of the patient's age, biological sex, weight etc. then you can also put in a checking system at the prescription level, which checks that the amounts of drugs being prescribed are inside the guidelines for those drugs and drug interactions and which also flags up potential for abuse of these drugs.

That is adding value to the system.

Before this, you have to duplicate the existing functionality and add in a little extra robustness such as off-site backups with encrypted transport.

Scientists strangely unable to follow recipe for holy grail room-temp superconductor

Re: And that, my friends, is how you do science

Do you know how genetic scientists teach other labs to do their methods?

The recipe is fairly simple:

Take one researcher who knows how to do the method, and all the EXACT same materials that they used; same suppliers, same glassware, same disposables, same everything.

Repeat the method using the above kit, and repeat until it works reliably (which it never does at first).

When working, lead a researcher at the new lab through the method, step by step. When they can do it, teach others.

When several people can do the method, one by one swap the materials from the remote lab for ones available locally. Modify method as needed.

This is KNOWN behaviour; it really is not surprising that a complex method cannot be reliably copied using just a paper. Indeed, research materials that are supposed to be equivalent from different suppliers can actually be very different; in my old field of research the agar gel used by European researchers and American ones was subtly different; this meant that setting up diffusion gradients of sex pheromones took mere hours in Europe and ten times as long in the USA.

Yes, I was working on sex pheromones. Yes, videotaping was involved. No, the videos have not survived the test of time.

Re: Statistically inevitable

Yes, but if you've a techie who already seems to be going off the rails and who is racking up both disciplinary problems and other red flags, then why hasn't this potentially hostile actor had his access to secret stuff revoked?

TETRA radio comms used by emergency heroes easily cracked, say experts

Re: Spectacularly irresponsible.

There's already another problem with police TETRA; it uses specific frequencies and the handsets like to chatter away to their base station to maintain contact with it. This means that a TETRA handset is like a beacon that says "Police here" to anyone with a software-defined radio system capable of detecting the chatter. Such systems cannot of course decrypt the chatter, but they can crudely determine range based on signal strength.

This is therefore useful to actual and potential criminals as a way of spotting when the police are in the area.

A better system might be to use existing 4G and 5G data services and impose this service onto the operators as a cost of doing business in the UK, with the police and other emergency services' comms being given a much higher priority than normal communications.

That would solve the coverage problems that plague TETRA, solve the encryption woes if a suitable scheme can be employed, and since the chatter of handsets would not be trivially easy to distinguish from normal systems without intensive packet scrutiny then this attack would cease to function too. It might also solve the scarcity of handsets, since a custom Android ROM running on consumer handsets might well work quite well.

Re: Proof of the UKs diminishing political structure ...

The UK government has already had experience of precisely how much notice Apple and Google take of their views during the time that COVID-19 contact tracker apps were being set up. The UK produced a horrible pile of rubbish which the two tech companies looked at, and flatly refused to have anything to do with. They then produced their own rather more elegant and much less intrusive options and presented these to the UK government as a fait accomplis, take it or leave it.

The UK government then accepted the inevitable and took this option.

The same will happen with encrypted comms apps; the government will be quietly ignored by all and sundry and will eventually bow to reality and confine themselves to making the tax code ever more complicated.
