UK.gov to tech industry: Hands up who can help cut teachers' admin

Brewster's Angle Grinder

Well full fact says budgets have been cut in real terms over the last couple of years.

And private schools skew the figures. My back of the envelope suggests we'd be level with Ireland without them. (The average state funding per pupil is around £5200 (by eye from the graph). But 7% of students are in private schools and average private fees are £17,000. So that raises the per pupil average over £6000.)

That's before we take into way all the ways money has been used for non-educational outcomes.

Visa fingers 'very rare' data centre switch glitch for payment meltdown

"It was a backup switch within the primary center that failed to activate due to a component fault in another switch."

So I guess it was the backup switch's psychic circuit that "failed". It should have ignored the status signals telling it the main switch was okay and deduced it was having a bit of a turn.

Automation won’t take your job until the next recession threatens it

Brewster's Angle Grinder
Silver badge

Re: You'd think interest in automation would peak

When things are going fine, nobody wants to rock the boat. And spending on R&D to "stay still" is robbing shareholders and executives of their just deserts.

But in a recession, you've gotta find savings or the CEO salary might take a hit. Or, worse, the company may even fail and the CEO be forced to find another job. So you fire someone, and if the machine can do 70% of their job, you're onto a winner. (Or you don't hire someone and put in a machine in instead.)

Re: How large of a tide would that have been?

"How large would it have looked in the sky?"

About 9 times large than today. But it would be 80 times fainter - because the light it reflects, which hasn't changed, is now spread out out over a much larger "area". My fag packet suggests the full moon would only be about as bright as Sirius. So it wouldn't be visible in the day. Eclipses would be far more common, though.

I used to know the numbers about tidal heights. But I can't fault the answer above (except for using miles). Remember tides are very complicated, shaped by local geography, and the sun is responsible for about a third of the height. However the most important thing to worry about is not the ocean tide but the tidal movement of the Earth's crust. Imagine the fucking earth's surface raising and shrinking by 100s of metres twice a fucking day.

The closet analogy I can imagine is having a loaded gun in your backpack, and the safety fail and the gun go off. Whatever the idiocy of doing that, the mechanical failure played a role.

"It usually takes around a week for Apple to either approve an app or give some indication as to why it has been rejected."

"Thanks to the Internet. It's a case of "release now and download updates/fixes later""

There's truth to this. Before the web it really was quite difficult to deliver patches. It required physical media and an instruction booklet. And that shrink-wrapped packaged had to be got to the user. That cost money.

These days there's no need for physical media or instructions, because it's automated. The cost is just the bandwidth (or not, if it's peer-to-peer).

"There is only one universe..."

The pedant in me says that's true by definition. But we're talking about QM, not string theory and eternal inflation. And, hate it though you may, Many Worlds is as (in)valid as any other interpretation.

These days I view it as naive, and unlikely to produce an insight that solves the problem (and, on that basis, probably false). But we can't dismiss it because we find it aesthetically unattractive. Many Worlds has the same order of complexity as any other interpretation of QM and can fully explain the facts.

Android devs prepare to hit pause on ads amid Google GDPR chaos

Brewster's Angle Grinder
Silver badge

First, we're talking about *apps* not browsers.

Second, people might dislike adverts, but most people would rather put up with them than pay hard cash for apps. That's true of the wider internet, and historically has been true of ad-funded free-to-air TV and ad-funded free papers and magazines. It's not the producers who dictate this but the consumers. Without ads there's less content and the budgets of the content there is, will be smaller.

Of course the joy of such as system is some of us can be free riders -- blocking and fast-forwarding through ads, while still getting the free content. So long may it reign. But I freely admit I'd part of the problem and try not to bitch too much.

That time of the month where I collect downvotes

This thread makes the case for the legislation. None of you grew up with instant access to more porn than even the most hardened wanker could consume in a lifetime. The government isn't aiming to build an impenetrable barrier; the point is to reduce the flow back towards that level.

Of course it would be better if we had better sex education and more responsible parenting. It's all but certain there will be some embarassing leaks. And It's likely it will concentrate power in the hands of one or two companies and put small providers out of business. But none of you are campaigning for solutions to those problems. You're just screaming "No, don' t take away porn from under 18s", on the grounds it might make your lives a tad stickier.

Outside the libertarian trend, everybody looks at the long list of things we stop under 18s accessing, and says "fair enough" to adding porn to the list, and then starts googling VPNs.

Market contraction incoming

You can't blame individual app developers for what's a broad cultural choice made by users. Nobody wants to ruin their app with ads. But non-technical (Android) users have been unwilling to pay and very willing to give away their privacy.

Maybe all Android devs unanimously saying "you've got to pay" will force user to start paying. Or maybe people will manage with less and devs will go out of business.

"but I'm pretty sure an 286 could have run a pre-emptive multitasking "

There's nothing magical about preemptive multitasking. All you need is a timer: dump the registers, switch stacks, restore the previous registers and resume. We used to do it on 8 bit machines. You could do it on DOS if you didn't reenter the OS.

Re: "without implementing a full 32 bit architecture"

"It wasn't easy nor cheap to add all the required silicon structures to implement a full 32 bit architecture."

I'm sympathetic to this. I spent enough time programming 8086 assembly that I have a soft spot for all its quirks. But the MC68000 arrived a year after the 8086 and showed what could be done.

"8 bit CPUs used even weirder ways to access more than 256 bytes..."

The ones I used in anger all had 16 bit address registers and 16 bit address buses. Though most had legacies of darker days.

Astroboffins score a first by spotting traces of helium on an exoplanet

Brewster's Angle Grinder
Silver badge

Re: Natural Reactors?

In your theory were correct then Jupiter (10% helium, by volume) would have one hell of a radioactive crust.

It's true, most of earth's helium is radiogenic. But that's because we didn't have much to start with and we're too light to hang on to what we had. (Remember helium is pretty inert and doesn't get tied up in chemical compounds.) This planet is a gas giant, about 40 times the mass of earth, and would have no trouble hanging on to its helium, if it didn't have its face rubbing in the star. (Mercury: semimajor axis ~0.4AU; WASP-107b: semimajor axis: 0.06AU)

Re: Canned Quantum Unicorn Meat?

The final paper is free to read and that particular sentence has been toned down and tweaked. It now says:

Entangled mechanical oscillators combined with phase-sensitive measurement systems can find practical use in the precise reconstruction of classical resonant forces, which has implications for quantum metrology.

Which is a lot more sober.

Some sketchy googling suggests interferometers (and other "resonant" "mechanical" systems) suffer from noise well above the floor given by the uncertainty principle. But with entanglement you can "reconstruct" the missing information and get close to the Heisenberg limit. And I think that's all that's being said.
