Core blimey... When is an AMD CPU core not a CPU core? It's now up to a jury of 12 to decide

Brewster's Angle Grinder Silver badge

Re: The proof

Yeah, I'm still running a Phenom II 3.2GHz. It's lovely. With a modern graphics card it has no trouble playing games on my modest screen. (And Doom 2016 was a lot of fun.) If I resume doing serious amounts of compiling, I'll get something newer. But I don't see the need for webdev.

And I'd've avoided the FX chips precisely because I'd expect real world work loads (*cough* gaming *cough*) to perform as badly as you suggest. Maybe compiling could use all eight cores, but I'd expect most modern apps to lean heavily on the FPU. Case in point: javascript -- the kids today barely know what an integer is, let alone how to ensure javascript doesn't devolve into floats, or worse, denormals.

Brewster's Angle Grinder Silver badge

And the CPU did. (Four, in fact.) But the issue is whether an FPU is part of the central "core" or part of the outer periphery.

This could go either way, based on the quality of the lawyers. The AMD argument is it had eight units that could execute instructions. The plaintiff's argument is that a bunch of instructions he reasonably expected to execute without contention had to contend with those from another execution unit. I think that's a slightly harder case to make; there are many instructions which could be contended and if it mattered that floating point instructions were uncontended then the plaintiff should have read the small print. Still I could easily see a jury viewing that naivety as being reasonable, particularly as even a majority of El Reg readers seem never to have had to issue an WAIT/FWAIT instruction in their lives.

Re: Re. Chimeras

Mosaicism is different to microchimerism. "Mosaicism" or plain chimerism is where two zygotes have fused in utero and organs develop with differing genotypes: you can literally end up with one arm with one genotype and the other arm with a different one, or with two different blood types; the case you're referring to (Lydia Fairchild) was an example of this. Microchimerism is where there are a few stray cells with a different source; mothers, for example, often have cell lines from their children lodged in their body or floating in their blood.

And. for the record, I think we can rule out both. Spitting in a test tube or swabbing a cheek wouldn't spot microchimerism. And even if the experts hadn't looked at the twins' DNA, what are the chance of two eggs being in the womb, one of which splits into two foetuses and then one of these foetuses fuses with the fraternal egg in such a way that the surviving children look identical but have different saliva glands?

Dark matter's such a pushover: Baby stars can shove weird stuff around dwarf galaxies

Brewster's Angle Grinder Silver badge

This paper draws a lot of inferences. But there's just one factual discovery: galaxies that stopped star forming 6 billion years ago have more dark matter at 150 parsecs from the centre than those where star formation is ongoing today. This conclusion is based on examining 8 dwarf irregular and 8 dwarf spherical galaxies, and then throwing in some maths (but I don't think there's any obvious reason to doubt it for the 16 galaxies they examined).

Re: Tail wagging the dog?

Isn't that's a bit like saying "it's not that this bonfire has heated up the air, it's that everywhere else has cooled down"? Or looking inside a fridge and saying, "it's not that the interior of this fridge is cold, it's that everywhere else has warmed up"?

They've extrapolated data to a point where they can compare it with a model that "heats" the initial dark matter in a galaxy, and it fits. Whereas a cooling model would, presumably, produce a different result.

Re: Dark matter doesn't interact with light, but

It's just talking about the dark matter speeding up as it weaves around space.

Think about how a spaceship can pick up speed by slingshotting round a planet. The idea is similar things happens to dark matter in the turbulent space around star formation. That increase in speed is an increase in kinetic energy -- i.e. the dark matter's temperature increases or it "heats up". (The abstract even puts "heats up" in scare quotes.)

Re: Roman numerals @Sequin

Roman numerals are like caps lock for numbers; they're a meta channel for conveying contextual information and a variation that adds to the rich texture of English.

after all we could do away with capital letters and punctuation because you dont use them in speech although perhaps theres a need to indicate a pause or the rising intonation of a question but why not go for the minimum and while were at it switch to phonetic spelling and get rid of any words whose meaning is so similar as to be all but identical to another

£10k offer to leave firm ASAP is not blackmail, Capita told by judge

Brewster's Angle Grinder Silver badge

Lawyers are sticklers for meaning

I've never heard of it happening. And it's sounds really improper. But the OED says blackmail is:

The action....of demanding money from someone in return for not revealing compromising information which one has about them.

So for it to be blackmail, she would have to be demanding the money and threatening to "go public" if she didn't receive it.

But she's already gone public and doesn't want the money. So it certainly sounds coercive, and it might have been bribery, but it wasn't blackmail; it's the wrong way round.

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

Brewster's Angle Grinder Silver badge

Re: Complications

"If the accuracy of atomic clocks is dependent upon gravity (as just demonstrated), we may have a serious problem with the definition of time as that is currently defined using atomic clocks."

There wouldn't be a problem with the definition of time. But we would (and do) have to be careful comparing different clocks.

This actually caused a problem early on and the time signal formed from atomic clocks (TAI) ended up being a smeared average of clocks at different altitudes. I don't know why this mistake was made, since it was well understood that time on the earth's surface would be different to time at it's centre or at the centre of the solar system, and we had (and still have) different timescales to deal with this.

I haven't looked at this case, but Britain has a long and proud tradition of "gold plating" European directives. So I suspect, if I bothered to follow the link in the article, I'd find we were doing way more than was required. It's a habit which has fed our distrust of the EU and yet it originates in Whitehall.
