Conventional wisdom is that China props up the North Korean government because if it collapses, China will have 25 million starving refugees at their doorstep (not that they don't already, but for now at least they aren't China's problem).

What actions China considers the best ones to accomplish that goal, and whether they are correct about the efficacy of their approach, is way above my pay grade.

If they want to launch it at us, they've pretty much got to get it small enough to fit in a car.

Not that it really matters anyway -- the NPRK would only launch a nuclear first strike as a form of ritual suicide. MAD still applies, even to nasty little third-world dictatorships, and launching a single nuclear missile (or even a few of them) makes no sense strategically; in a nuclear war you need to knock out your opponent's nuclear response capability or they're going to respond by nuking you to ashes in short order.

If North Korea did decide to nuke someone, they'd be much better served to smuggle the nuke aboard a ship and detonate it in a harbor somewhere; at least then they'd have some fig leaf of plausible deniability. An ICBM launch showing up on every nation's satellites/radar wouldn't leave any room for doubt at all.

Server 2016 is going per core licencing which means less cores overclocked

Given the drive to eke every last bit of economy (both dollars and joules) out of commodity server hardware, I see two possible outcomes for that: either future versions of Windows will have to reduce their licensing costs in the multicore scenarios, or most software will get ported over to other operating systems whose licensing costs are lower. (I'd imagine the latter is more sensible, since paying to license a GUI-based OS seems silly when running server software on a headless machine in a data center, but far be it from me to second-guess the IT industry)

Comment Re:speculative execution etc. With 1024 cores ... (Score 1) 337

With 4096 otherwise idle cores, it can make sense to calculate 1,000 possible scenarios in parallel and then ignore the 999 options you didn't need.

Well, maybe from a strict minimize-time-to-result perspective, but if we're also trying to minimize power usage (and given the subject of this article, we presumably are), then I'm not sure you're going to get any kind of efficiency win by doing 1000 times the necessary number of computations and throwing away almost all of them.

And in *two whole years*, they should have been able to establish that it was validating malware.

Is the app in question actually malware, according to Apple's definition of the term?

Or to put it another way, how evil does an application have to be before it should be labelled as malware? Is there a formal policy on this posted anywhere?

I still keep a landline for emergency, it's never failed in 40 years.

Of course, the flip side of that is that you're likely paying a significant monthly bill to keep that reliable land line active.

My building's two front-door call boxes were each using a land line for their call-up function, and they were costing the HOA $65/month each. I switched them over to VOIP, now they cost the HOA about 25 cents per month each (not including the $23/month DSL service, since we had that set up anyway for unrelated reasons).

Junk making the front page that talks to me like I don't already work in IT or understand how common household technologies work.

Who are you? I didn't understand how DSL worked until I read the article, now I do. (Well, probably not, but now I know more than I did)

Comment Vertical solar panels? (Score 1) 213

People are getting so distracted by the word "luddite" that they've neglected to ask the important question: to what extent does having all of the solar panels mounted vertically affect their efficiency?

Granted, it looks cool, but I presume that most solar arrays are mounted horizontally (or at an angle determined by their location's latitude) so that they are as close to perpendicular as possible to the sun. Unless this installation is *really* far from the equator, it seems like they will be generating less electricity than they might have this way.
