Re: Now if they could do this with neutrinos...

"The detector might require excess baggage charges though. Fermilab's current neutrino detector is a sphere continuing 800 tons of mineral oil and 1200+ photomultiplier tubes."

I'm scratching my head trying to work out which neutrino detector you are referring to. I'm aware of five neutrino detectors operated by Fermilab. Three of these are the detectors for the Short-Baseline Neutrino Program, being the Short-Baseline Near Detector, MicroBooNE, and ICARUS. These are all Liquid Argon Time Projection Chamber designs filled with 270, 170, and 760 tonnes of liquid argon respectively. The detectors are cylindrical. No photomultiplier tubes. The NOvA programme has two rectangular detectors made of stacks of blocks filled with mineral oil. The far detector is 50x50ft by 200ft long. Each module is 50x50x6 feet. Again no photomultiplier tubes. The photon detectors are fibre optic with solid state avalanche photodiodes. The near detector has 300 tonnes of mineral oil, the far detector has 14,000 tonnes of oil.

Competition watchdog? We've heard of it. But emergency comms firm still on track to Airwave hello to £1.2bn

The right tool for the job

I still have not encountered a Conservative member of parliament who will answer the question which system would you rather have if your job description included "Meeting some of the most violent members of society and detaining them". Airwave has features that are superior to those touted for the 4G (aren't we on 5G these days?) replacement. For a start a big, friendly, emergency button that only needs to be held down to transmit a distress call. The person who needs help may speak but does not necessarily need to because the call alternates between send and receive, the operators are alerted to the call which has priority over all other traffic, and the operator can hear what's happening. The 4G alternative is "hang on, would you mind not beating me with a shovel while a make an emergency call. After I get this phone to start up and just as soon as my credentials have been verified."

Airwave also supports connection into command and control systems and displays the status of the user which can be changed by the user to show what they are doing. The C&C system then updates the information. It's all simple and rugged. The only failing with Airwave is that government did not take the option to fit their terminals with a SIM meaning that users must carry around a phone as well as Airwave.

The only issue here seems to be, yet again, those in government making poor policy, not funding it properly, and signing contracts that hand the supplier enormous amounts of cash.

Re: Do WHAT ‽ ‽

"We have a network which can not only solve (previously) unsolved problems, but solve them 100 million times faster than they can't be solved..."

That's a, possibly deliberate, misunderstanding of what was said. The article makes it clear that the problem was a chaotic orbital mechanics three-body problem. These problems can be worked out as a formula, they are compute intensive to solve. So the Edinburgh researchers computed (very slowly) the solutions of a large dataset. Having done that they then trained a neural net using the these known solutions. Then they tested the neural net against a similar set of problems for which the solutions were not known. These "previously unsolved problems" were solved at speeds up to 100 million times faster than the standard approach. The language is clumsy but the meaning is clear if you read the paragraph that explains the approach.

Re: Outside the cocked hat

"There was a nice period where the difference between True and Magnetic North where I was regularly flying was less than a couple of degrees."

Late 1990s for what felt like forever at the time. I got out of the habit of bothering with the correction at that time. Much of sailing around the Isle of Wight is pilotage anyway, so for a decade or more I did it without GPS/Decca or even bothering much with a chart.

Lotaresco

Re: It's worse than you think...

I just spent ages composing a similar reply. The error on each bearing will be randomly +/- the actual bearing. Hence you can be either side of any of those lines meaning that being outside the cocked hat is more probable than being in it. Many navigators have had an unfortunate rock/hull interface as a result of assuming they are safely inside the cocked hat. Even GPS doesn't eliminate unfortunate position errors. For example I nearly dinged an unlit buoy in the dark despite GPS telling me I was a couple of hundred metres away from it. Low tide and a strong current mean the buoy had been pushed to the end of its chain and there was a lot of chain to cope with the tidal range. There's a reason why "Ooops sorry, left hand down a bit." is the Cry of the Navigator.

"Luckily for her she was euthanised is space."

Sadly Laika was not euthanised. She died in distress and probably pain when the heat shield failed.

'Unfortunately, loss of the heat shield made the temperature in the capsule rise unexpectedly, taking its toll on Laika. She died “soon after launch,” Russian medical doctor and space dog trainer Oleg Gazenko revealed in 1993. “The temperature inside the spacecraft after the fourth orbit registered over 90 degrees,” Lewis says. “There’s really no expectation that she made it beyond an orbit or two after that.”

Sinclair and the SSD

It's one thing I haven't seen any journalist mention is that back in 1989 Sinclair pioneered solid state storage with the Anamartic SSD. Initially 40MB but soon 160MB of storage. Which may sound piffly today but at the time my computer was a Mac SE/30 8/80 - 8MB of RAM and 80MB HD. Friends with PC/ATs and IBM PS/2s looked at the Mac and declared that no one would ever need that much storage! So Anamartic's product was cutting edge.

Sinclair had that rare thing, vision. He didn't necessarily know how to get to where he wanted to be and his ambition exceeded his talent more than once, but if he'd been in Silicon Valley rather than Cambridge, I suspect he'd have been a multi billionaire and Sinclair would be a name alongside Microsoft, Apple, Tesla.

We also shouldn't forget that the reason we had Acorn, the BBC micro, and ultimately ARM is that Sinclair ticked Chris Curry off enough that he left Science of Cambridge (the precursor of Sinclair Radionics) and created Cambridge Processor Unit Ltd which became Acorn.

Re: Too lenient

"It will never happen, because one thing leads to another, and it could end up with a director of a UK multinational being personally held to account for the actions of the company they control."

I used to work for a pharmaceutical company. The directors were always inclined to grumble about the costs of doing business and they hated the constant complaining from the scientists that products had to be thoroughly tested and shown to be safe and effective. There were occasions where some director or other would try to influence people to launch products that were "marginal" just so they could try to recoup their investment. They didn't care that someone could go to jail because the person going to jail would be a scientist that they saw as a lackey.

Then the FDA changed the rules, introducing "strict liability" that mean that the directors were personally responsible for the safety and efficacy of all of their products. Overnight the business changed suddenly money was no object, every product was to be tested thoroughly, suspect products were taken off shelves, side-effect monitoring (pharmacovigilance) became a well oiled machine and we IT bods were busy creating systems to contain, analyse, and present the data.

It's amazing what fear can achieve.

Re: influencer

There was quite a bit of detail about the directors of this scam company in the Daily Record. I have to say that the only thing that the person in question managed to influence was a dry heave.

Vanity flight

OK, it's easy to admit that every billionaire involved in space is more wrestling with their own ego than the technical challenge. But Bezos seems to be suffering some massive inferiority complex over this, which may explain his desire to get into space in person before Elon Musk. Both Bezos and Branson seem to be aiming at the same achievement level - suborbital hops - while Musk is giving the impression that his ambition is a Mars landing. The recent Blue Origin hop looked awfully like nothing more than a "Rocket for the CEO" vanity project.

"Is a SOC even enough when you're up against state-backed actors ?"

Not all SOCs are created equal. Some SOCs are certainly enough when up against state-sponsored actors. The rest of the network has to be appropriately engineered too. A SOC, of itself, isn't sufficient. Also the SOC team has to be on top of its game.

Re: "The Art of Hacking"

" if you're spending all this money getting courses made that are supposedly useful in cyber defence, why not just publish them so everybody can have a gander."

Because these courses are not created by UKGOV, they are commercial training courses that the government buy on a per-seat basis. Since they don't own the IP, they can't sell or give away the courses. A bit like you can't (legally) make copies of Hollywood DVDs[1] and sell them in the marketplace.

Re: Back in the 80s...

"And always getting such offers in writing, then checking that they're ironclad before proceeding"

The problem being that just about every contract for sales staff specifies that bonuses can be withheld on a whim.

I'm glad that as a scientist I didn't have much to do with sales, although even there we got shafted too. I worked for a company that made a product that was brining in about £3m a year. Sadly it was costing about £2.5m to manufacture. I was asked to have a look at it and work out a way to reduce costs. I examined the manufacturing process and worked out the most length and expensive part of manufacture was completely unnecessary and came up with a much cheaper alternative. Cost of manufacture per unit fell from £5 to 23p. Cost savings bonuses were 15% of the saving, so I reckoned that left me looking at a bonus of about £300,000. What I actually got was 12 bottles of wine, a pen and the undying thanks of the directors that lasted for about 24 hours.

More galling was that the sales manager got an award for improving profitability and a new company car.

Lotaresco

Back in the 80s...

Someone I know was once given a sales portfolio of "unwinnable" contracts. The sales team had tried to bid for all of them but had failed. They were promised a 10% sales bonus on any of the contracts they could convert. A quick look made it clear that the pitches made to the potential clients hadn't been very good and the sales team were not interested in the capabilities of the systems. They just wanted to sell "product" and didn't care what it was. So every bid response was rewritten and tailored to the organisation letting the contract. Soon orders rolled in and within a year contracts for £10m let.

When it came to bonus time the bonus paid was less than £60K. The employer was questioned about which bit of 10% they didn't understand. The response was "Yes, but we didn't think you'd make any sales. We're certainly not going to pay you £1m!" They left the company and the order book collapsed again.

Re: Probably..

"Source?"

Note that I stated "It is claimed", not "I claim". I suspect you may be knee jerking a little here. The jury is not even convened to fact check the claims. However news reports exist and are distributed across the political spectrum. There's a report in The Telegraph here for example. If you want a more reasoned discussion then the Marshall Project Report has a detailed analysis, this shows a rise in some crimes, finds alternative explanations for some of them, but does have a conclusion that some crimes increased and others are probably not affected by defunding. As they say "Well, it's complicated."

Re: Guy Montags worst nightmare...

"Still, looks more like a remote control drone to me rather than full-on robot."

They look more like robots when you see one being used in a work environment. They actually do simple[1] decision making, including knowing where to place their feet to climb or descend stairs, stepping over obstacles and performing autonomous missions. They actually make decisions on the best way for them to perform a mission and over-ride the instructions given to them by the operator. Watch Adam Savage of Mythbusters showing off how Spot works and how he works out his route.

[1] Not that simple in fact. Stuff we do without thinking such as stepping over an obstacle that wasn't there last time we walked on that route, for example.

The owner's manual is a worthless pile of bumf created by the manufacturer that tells you not to drink the battery acid and how a steering wheel works. If you lose one you need a pay a dealer a few Euro to get another one. It doesn't prove ownership of the vehicle. The CG (or Luxembourg equivalent) is an important document that proves that the vehicle is registered. It isn't proof of ownership either.

This entire "cyber" nonsense is a concept of a government that is composed mostly of PPE graduates. That's PPE, the degree that covers skimming reference sources, bullshitting and busking essays. They genuinely think that any subject can be skimmed and understood (to the level they consider it necessary to understand) any subject. They are disgusted at the costs of IT security. I have been told by several of them that they think it's revolting that graduates of red brick universities, mere "grammar school boys" should be paid as much or more than a cabinet minister gets paid. We're the wrong sort, we went to the wrong place, we are very much "non-U" and it's disgusting that there are very few Eton educated individuals in IT. Apparently.

They are setting out to get the costs down and degrade the profession to a box-ticking exercise. Sadly there are far too many within the civil service who are keen to help them. They are also enraged that a consultant in industry makes several times what they earn in Cheltenham or Milton Keynes. Therefore the entire profession is being worked over with lukewarm schemes such as "Cyber Essentials" and the NCSC sponsored MSc. Add to that the advertising campaigns which attempt to push people with zero interest in the subject into "cyber" and you have the reason whey I'm looking forward to retirement.
