You mean this article? Albeit the summary was poor, but it covers the firmware hacking.

And FYI, if anyone actually takes the time to read the Kaspersky report they'd catch that the infection is believed to have been done on thousands to tens of thousands of computers, NOT "most HDDs". The firmware has the capability to infect most HDDs, but most HDDs are not infected - according to the very source report itself.

Which should be obvious. Because if you're the NSA and you're writing a super-infection to use against top-level targets, the last thing you want to do is have it on every last computer in the world, increasing your likelihood of being found by many orders of magnitude. The NSA's preferred method of infection is interdiction - intercepting objects while in transit to targets, such as CDs or hard drives, infecting them, then letting them continue on their way.

Once again, the NSA doesn't give a rat's arse if you're going to the Pirate Bay to download I Am Legend. It has far more important things to worry about, like people building atomic bombs and invading other countries.

Whatever they convert it into, New Drachmas or Cryptodrachmas, it's still going to devalue like crazy. Both, being backed by the same entity (the state) will have the same credibility problem. Except even moreso for the cryptocurrency because of all of the concerns that carries with for many investors.

There's also this big lie that "Greece has been saddled with debts that they could never pay". Greece's state assets are worth an order of magnitude more than their debts. They could sell off a tenth of them and have all of their debts in the clear right away.

Obviously, they don't want to privatize everything, and I don't blame them. But the concept that this debt is impossible to service is simply a lie. They just don't want to. Heck, they could do it without excessive pain to the middle class or extensive privatization if only they'd go after their wealthy - there's a couple dozen Greek billionaires and countless more in the next eschelons. And these are the biggest tax dodgers who don't pay anywhere close to their fair share. But Greece is apparently either unable or unwilling to go after them.

It's easy for Americans who've never had to live with a weak, low circulation currency to say "EURO BAD!". But they've never seen the consequences. How even in a good economy your money steadily becomes more and more worthless because inflation of such currencies is almost always worse than that of stronger currencies. How you pay out the nose for loans because of the higher risk of inflation or currency swings. How many companies won't even work with transfers to / from your currency.

Big, strong currencies offer serious benefits. America has been given a *massive* economic boost due to the widespread usage of the Greenback. Their economy would be nowhere near what it is today if each state had its own currency.

The fact that the Troika hasn't been willing to give one iota on the Greece issue should be enough of a reflection on how little consequence they think an exit of Greece from the eurozone would be. Germany in particular doesn't want to give any ground (I imagine all of the nazi-name calling has played no small part), but they're hardly alone, many countries are taking a very hardline stance on Greece. Most parties feel that the consequence of giving way to Greece could be significant, but the consequences of their exit - while not completely painless - would not be that dramatic.

On the other hand, in Greece, there's only one route for exit, and that's capital controls (or a rapid conversion over the weekend) where everyone's assets are converted to some kind of new-drachma, which instantly devalues to half its value or less. Which is why everyone is taking their euros out of the banks, they're not stupid (unfortunately, thieves aren't stupid either, breakins have become an epidemic as they look for people hoarding money at home).

I can't see a cryptocurrency helping in any way... if anything I'd guess it'd only serve to unnerve markets even more and lose even more value as a consequence. I could picture it maybe as a simultaneous and rate-locked currency to a physical New Drachma, maybe. But it sounds IMHO like an incredibly risky move even then. I mean, one presumes for example that there's a government-controlled master key to "print" more cryptocoins? Then that means that your entire economy can be crushed overnight by someone hacking, physically stealing, misusing, cracking, or whatnot your master key. Isn't that an unnecessarily big risk to take? And on an individual level it seems full of problems as well...

Don't get me wrong, I don't think cryptocurrencies are inherently an evil or shouldn't exist. But I would have serious second thoughts about such a massive nationwide rollout on a country that's already in chaos.

Yes, aluminum is slowly becoming more adopted - although "slowly" is the operative word. Corvettes are not mass manufactured (tens of thousands per year) and are made of single-layer e-glass with polyester, which kind of sucks. Supercars are built better but are in much smaller quantities. And the point of needing to make them affordable and scaling up, that's my point. :)

You're joking, right? Before Tesla the stereotype of an electric car was a nerdy thing with the performance of a golf cart. They completely changed the public perception of electric cars, built vehicles with double the performance and range of the previous best electric cars, getting some of the highest car reviews and satisfaction ratings *ever* given for *any* type of car, and managed to start a brand new car company with a huge valuation, the first new US car company to make it big since the 1930s. Give them some F'ing credit.

a legacy of factories not suitable for modern materials

A widespread transition to composites (which I really, really hope for) could do that, in a way that a switch to aluminum or other metals couldn't (working with aluminum isn't the same as steel, but you still have the basic principles of stamping, cutting, molding, welding etc, which all get thrown out the door when working with composites). But someone needs to find a way to make the composites competitive in a mass-manufacturing, non-niche environment. And preferably when I say "composites" we're not talking single layer E-glass and polyester here.... at the very least it needs to be foam or honeycomb cored with a vinyl ester resin to give the strength and longevity desired. Carbon fiber and epoxy would of course be even better if a good price point can be met. And hopefully in the future we'll be able to affordably get rid of more and more of those hydrogens in the structure... reinforced graphene/ta-C would probably be pretty close to the ultimate manufacturing material one could get, combining the highest known tensile strength with the highest known hardness and compressive strengths.

No, the GP is correct. The requirements for vehicles are radically different for portable electronics, and this leads to very different design choices. Tell me when was the last time you saw an iPod with an air conditioner just to cool its battery pack (which sometimes runs even when the iPod isn't in use), or a heater for cold weather charging? When was the last time you saw a iPhone with a battery that was warrantied for as much as a decade? When was the last time you saw an iPad that was rated by the manufacturer to have no problems after sitting out every day every winter in temperatures of -20C, summer temperatures of +40C with no shade, etc? When was the last time you saw any sort of portable electronics that broke its batteries up into separately sealed canisters that prevent fire from propagating from one to the next, or that can withstand a highway-speed collision? Portable electronics generally don't even do any charge balancing, let alone the sort of "be able to handle the loss of entire clusters of batteries" sort of management that vehicle packs have to be able to do (eg, rather than single cell or a couple-cells-in-series like consumer electronics, the Roadster has 6831 cells clustered into "bricks" of 69 cells in parallel to minimize the effects of individual failures, 9 bricks series per sheet, and 11 sheets, with moderate monitoring and control at the brick level and heavy monitoring and control at the sheet level).

The requirements are not similar, and as a consequence, neither are the packs.

Wrong again. Energy density is of critical importance in both applications.

No, you are the one who is again wrong. EV battery packs are generally significantly lower energy density than portable electronics battery packs, AND they generally run at lower DOD ranges, not charging up to full and not being allowed to even near total discharge. Often a lower-density chemistry is used as well for the same longevity reasons, such as a phosphate or manganese spinel (although a couple manufacturers, Tesla being the most notable, currently use cobalt 18650s). This sort of careful charge maintenance and lower density chemistry election, plus charge balancing, temperature maintenance, and fault isolation and tolerance are necessary to meet the sort of longevity demands of vehicle consumers, which are very different from the longevity demands of users of portable electronics.

The two top demands of EV battery packs are longevity and cost, and these far outstretch the importance of energy density. People could give a rat's arse if their car is 50 kilos lighter if they can't afford to purchase it or have to swap out the pack after three years. Don't get me wrong, weight is an important issue (mainly in terms of ride quality, and to a smaller degree efficiency), but it's not on the same order of magnitude of effect in terms of marketability as longevity and cost.

I think you're mixing some things up. The EV1's tires were standard size (P175/65R14) and only 50 PSI. They were low rolling resistance but nothing spectacular by modern standards. I certainly hope to see big advances in tires in the coming decades (we really need tires that can adapt to the circumstances, changing their pressure and thread area / type in contact with the ground area depending on conditions and driver demands), but there's no radical departures I'm aware of coming in the immediate future.

Yes, I would welcome any chance to see the US move to metric and catch up with everyone else.

I can't think of a single EV today that is "harder to open". But as stated I can easily envision Apple doing that. I can't envision any of the current manufacturers doing that.

It's funny to joke about, but I think the concept of them only allowing it to be serviced at Apple-certified garages would be quite high. They'd probably allow the tires and the like to be done elsewhere, but I have little doubt that they'd restrict access to any internals. And would charge a fortune for trivial tasks.

24 hours *if* you have air resistance. And then you're moving so slow that you barely get past the center.

Note that no vacuum is perfect so you will lose velocity. Their scenario should have started the person off at the south pole, not the north, for the extra altitude.

Note that the heat isn't really the materials problem that they make it out to be - it's an energy problem. You don't need a material that can withstand 4000, you just need cooling. And not linearly high cooling, but an exponential decline. The longer you cool the rock down to your target temperature, the deeper your effect on the rock temperature behind your tunnel walls, and thus the shallower the temperature gradient, and thus the lower the rate of heat loss. It's like trying to cool a hot house - the air conditioner really struggles in the beginning but it gradually becomes easier with time as the walls and everything inside the house cool down.

Now, the pressures, those are insane, and the normal approach to pressure maintenance on deep drilling - filling with a heavy mud - obviously wouldn't work here.

Sort of. Stealth aircraft are not perfect, they have some radar cross signature, and a low frequency radar significantly increases cross signatures. But the cost of this was vastly reduced range. The Serbs mentioned in the article had to wait until the plane was almost directly overhead to get a lock.

That said, that Serbian radar unit was incredibly clever, I've read about a lot of their tactics. They raided scrapyards all over the country and ripped radars off of old military jets and tweaked them to make dummies to confuse HARMs, they worked out down to seconds how long they could paint a plane before they had to flee and how to accurately predict when and where the coalition would fly what aircraft, they deliberately let jets past on bombing raids (knowing that they'd be dropping bombs on their own people) in order to get them on the way back when they'd be more vulnerable, they hand-modified their old Soviet radars to change their frequencies out of the design specs, swapping out capacitors and the like so that they wouldn't be detected by coalition forces and would stand a better chance at hitting stealth craft, etc. They were drilled and managed incredibly well. If the whole Serbian military had done as well as they did, Serbia would have held out far better.
