Comment Re:Summary of the exploit (Score 1) 81

So basically the signature only verifies the first instance of a file it finds in the archive, but when extracted it extracts the latest. In fact ZIP (and RAR IIRC) allow overwriting a file with a newer version later in the archive; probably a hold-over from the floppy-swapping and/or tape days when you needed such abilities.

Reminds me of the chimera file exploits that use the fact that many common file formats like ZIP and PDF will ignore extraneous data, scan into the file looking for a header, etc to make one file appear to be a valid file of many types. Often, virus scanners fail to notice this and will scan eg the PDF while ignoring the ZIP payload, but unzip utilities just scan forward until they find the ZIP header.

The real fail here will be the fact that at least half (if not 80-90%) of all Android devices won't have a patch released *period*, never mind people bothering to install the patch.

Comment By the way: With Obamacare... (Score 0, Troll) 59

By the way, with Obamacare (or any other single-government-payer system) you can expect such new treatments to NEVER be deployed - or even developed.

If such a new procedure succeeded it would mean paying a lot of extra money saving the person, after which it would mean paying MORE money as they live longer to collect more benefits, further straining an already self-bankrupting system.

Preventing this is what "death panels" are about.

(As a government official once said - about in 1979 or so, when the impending bankruptcy of Social Security was first being hand-wrung over - "We've got to get the death rate up to meet the birth rate.")

As usual, any kind of clinical use of this stem cell stuff is "ten years away". These guys are as bad as fusion researchers.

I'm sure they'd love to try it in a human dying of liver disease. But between the FDA regs, the self-appointed Medical Ethics czars, and the malpractice ambulance-chasers there's a lot of hurdles to jump before they MIGHT be allowed to try it (let alone deploy it as a regular procedure).

An Israeli style system will NEVER be implemented in the US because it runs totally contrary to the politically-correct postmodernist identity politics narrative that drives our current political monologue (no, not dialogue).

Suggesting it will be met with screeches of "RACISM!", the person suggesting it will forever be chased and shamed from the limelight, and we will continue staffing our airport security with fat, sticky-fingered illiterate highschool dropouts that barely speak understandable english and use their union to protect their do-nothing jobs while extorting more and more taxpayer money from the very people subjected to them.

That's asinine conservative clap-trap. What you are discussing is typical LEO profiling in the USA where dark skin is used as a cheap and poor substitute by the lazy and incompetent, which blinds us to very real threats (Timothy McVeigh anyone?). Racism doesn't just harm minorities, it also blinds us to both the potential achievements/contributions of the minority group *and* makes us ignore the threats that look like the majority.

An Israeli-style system requires a literal army of very personable, often friendly, intelligence officers who walk around both in plain clothes and uniforms, chatting people up about their life, their family, their trip. That's true profiling. You have to get a feel for the person and whether they are being evasive or acting nervously. Red flags mean extra screening. As others have pointed out, they use tricks like having an attractive woman chat up a single man, without him even being aware that he's being profiled (at least at first). This means you can't pay crap wages and demonize them as tax-sucking leeches; you need decent pay and benefits.

Typical conservative nonsense... cut taxes, use the resulting deficit to justify cutting workers, hours, and benefits, demonize government employees, then point to an under-staffed and demoralized agency as proof government doesn't work, thus justifying cutting back even further. Use the small surplus in boom times to justify another tax cut, then wait for the inevitable downturn and temporary deficit to justify repeating the cycle all over again. Make sure to throw in rants about political correctness, drum up a fake "war on Christmas", etc for good measure. It would be laughable if it weren't so predictable.

I visited him in the late '80s, along with a number of others of the hypertext startup I came out to CA to work for. It was sort of a pilgrimage to see the great man.

Comment An Appropriate Summary (Score 1) 229

Intel *does* make custom chips for outside people, contrary to what some people are saying. They sub out spare capacity, especially in older fabs. They just don't make them on their newest foundry processes (the ones that would be actually useful to a company like Apple) for a variety of reasons, the chief one being the newest processes are generally full to capacity. Even if there were some space available it wouldn't be near enough to satisfy Apple's demand for A-series chips. You have to remember, an A-series chip requires on the order of 150,000,000 units in the first year.

Apple has the cash hoard to get into the foundry business if they wanted, but it would take at least a decade to hire engineers and gain the experience necessary to cost-effectively produce stuff like 14nm 3D transistor chips, assuming you can navigate the patent minefield.

The only way such a deal would work is if Apple funded a new Intel foundry to produce Apple chips in some kind of long-term deal, but that would probably require Apple to spend double on the processors to give Intel the fat margins they want to even consider the idea.

I fully agree that in some magical world where this kind of deal happens it would give Apple a permanent advantage in the phone space, as no one would be able to come close to the performance and performance-per-watt of an A7-type chip made on Intel's latest 22, 14, or 10nm process; it would make all other phones look like a joke.

It just isn't going to happen.

Or Ballmer can have them report to the head of Entertainment and Devices Division in the meantime

That group doesn't seem to exist anymore.

which is the most logical thing seeing as Ballmer has no background in gaming or devices while waiting for the re-org. This person will most likely have more knowledge and expertise than Ballmer. Or appoint someone under Mattrick to be temporary in charge until the re-org.

Do you work at a large company? I do, and I can confirm that recoiledsnake is correctly describing how things work, at least in my experience. When a manager leaves without an immediate replacement it's common for the their manager to take over the group temporarily. (They are, after all, probably more familiar with it than anyone else in the company.) Getting a new manager up to speed takes time, and if it's temporary that's a big waste. Likewise, when you've got a critical deadline it's a bad idea to distract key team members by suddenly giving them another job.

Re-orgs are often decided on months in advance but not announced until much later, and the announcements are often delayed. The new person might still be getting up to speed. Particularly at the senior management level (which is visible to investors), it's important to have a clear idea of who's in charge.

Comment Re:What creates the temperature differential? (Score 5, Informative) 170

Does she put it in the fridge before using it or something? Or does it use the difference in temperature between your hand and the flashlight.

The latter.

If you RTFA you'll see she's using the aluminum flashlight body as a heat conductor and the "head" and other exposed portions of it as an air-cooled heatsink.

She's stuck the handle of the light into an insulating plastic pipe, cut a hole in the pipe, and stuck the peltier cell in the hole, with the "cold" side in contact with the flashlight handle and the "warm" side in contact with the hand. (I expect the next step is to wrap an outer aluminum tube around it to conduct heat from the whole hand to the cell, rather than just heating it with a patch of palm directly contacting it.)

Voltage boost converter between the peltier assembly and the LED (because the peltier cell she used was not stcked for the right voltage to drive the LED.) The LED shines as long as you hold it, if the air is cool enough. (She's used it for 20 minutes running.)

Also, since this is generating electricity from a temperature differential, rather than generating a temperature differential from electricity, wouldn't this be the Seebeck effect?

Yes. Seebeck discovered current generation from heat differential (with dissimilar metal wires and a compass needle), then Peltier discovered heat-pumping with current.

But, like most rotating electric machinery (where the same device is a motor or generator depending on whether you power it or twist it), the same effect is a heat pump or heat engine (depengding on whether you apply a temperature difference and pull power or apply power and pump heat).

The effect is now often called the "Peltier-Seebeck effect" in textbooks. The cells are typically called Peltier Cells because the efficient ones are manufactured mainly for heat-pumping, though they work just fine both ways.

Comment Noise canceling is NOT the key. (Score 1) 120

The noise-cancelling scheme sounds interesting.

If you'll read TFA a little more closely than the OP did, you'll find that the noise-canceling thing is NOT how they got the 1G-ish single-pair link to work.

What the noise-canceling thing is about is when you have TWO OR MORE pairs bundled into a single logical link. Then it figures out what the cross-talk between the individual pairs looks like and cancels THAT out. This lets the individual signal pairs run as fast as a lone pair and the total bandwidth of N bundled pair be N times the bandwidth of one, rather than substantially less.

But open source prevents this from happening because the source is constantly being looked at!

No, open source doesn't keep it from happening. Providers can stick any cruft in there that they want.

What it does do is make it much more likely to be discovered when some fool DOES stick it in there. Don't be surprised if you hear about a lot more bad stuff found in open source than you do in closed source, as a result. (At least until the bad guys wise up.) Try to find the malware in Microsoft's stuff, for instance. B-)

(Of course this stuff was found with a packet sniffer before anybody found it in the code. So it's an apples-to-oranges comparison and open/closed source has nothing to do with it.)

Comment I'm in Silicon Valley (Score 1) 395

I'm in Silicon Valley. I want to live in Nevada, far enough from the neighbors that I can't hear their HIFIs in the daytime or see their lights at night.

I want to live in Nevada so much that I built a house there - a few miles over the state line near Lake Topaz. Fully paid for. Marvelous view. Good neighbors. Also rabbits (jack and cottontail), quail, coyotes, deer, antelope, bobcats, cougars, and black bears. Gun laws are a lot different there, and I have a Nevada CCW that's also valid in many other states due to reciprocity (though not in CA).

For the Town House near work I also moved across the bay from Palo Alto. Just off the other end of the bridge, for less than I was paying in rent in Palo, I was able to BUY a two-story four-bedroom with 7,000+square feet of yard and remodel it. 200A electric service (two 20A circuits to each room for starters). Satellite TV and Cat 5E everywhere. (Only running 100M at the moment but I hear that with house-sized runs you can get away with 5e for gigabit Ethernet.) The yard is now a garden and orchard. We get most of our veggies from it - and our eggs. We were also on the Bay Friendly Garden Tour last year.

They tell me the city here on the Back Bay has a gang problem. But for several blocks around our house it doesn't. It's much like in Palo Alto (where the burglars worked their way down Loma Verde street and skipped only two houses - ours and the retired cop two doors down). It seems the crooks don't like to bother NRA instructors, and the wife's "Ducks Unlimited" sticker tells them she can hit a spot the size of a duck (or a human heart) with a shotgun, from 50 yards, even if it is flying at the time. B-)

Of course NV has no such crime issues. Even machine guns are legal there. B-)

Move to a SF or Oakland? By preference? You've GOT to be kidding.

Comment Re:worst description of polarization ever (Score 1) 82

I think of it as being analogous to injecting separate beams of light at different angles, having them bounce back-and-forth between the walls at different distances between bounces, and emerge at angles corresponding to the angles at which they entered.

Of course it's not angle of flight that's in question, but another property of the light propagation that can be varied to allow different beams to propagate down the fiber and be separable at the far end. But they're still separate because each beam's cross section at a given plane cutting the fiber has a different distribution of phase and intensity, resulting in different propagation mechanisms that conserve a property which can be used to separate the beams when they emerge.
