Comment Re:He's missing the point. (Score 4, Insightful) 133

It would be nice if people could learn to think in terms of threats that fell somewhere between "safe to ignore" and "extinction level event". Or could distinguish between "extreme and expensive" responses and "effective" ones.

9/11 could have been prevented by simple, conservative and inexpensive countermeasures. After 9/11 politicians droned on about how "9/11 changed everything," but the cold sober fact was that it in fact changed nothing. It just showed that some of the things sensible people had already been telling us to do (like reinforcing cockpit doors or getting agencies to work together despite institutional rivalries) really did need to be done. Instead "9/11 changed everything" became the rallying cry for every pet scheme that had heretofore been correctly dismissed as too expensive, hare-brained, or just plain dumb.

Which doesn't change the fact that something needed to be done. Here's the lesson I think we should take into this infrastructure debate: we should take sensible and conservative steps to secure infrastructure against terrorism now, before events put foolish ones on the table.

Or... what if anytime anyone called a residential number, a nickel was transferred from the caller's account to the callee's account.

That wouldn't stop anyone from making a call where an actual person is likely to be involved; the labor costs for a three minute conversation would swamp that. But it would discourage people from robocalling a hundred thousand people in order to turn up a handful of suckers.

And the public wouldn't have to pay a regulator to try to track down these boiler room operations.

I don't have to do anything. Even stored under ideal circumstances li-ion batteries lose capacity.

What matter is capacity relative to demand. In a phone like the Droid Maxx from a few years ago with plenty of surplus battery the phone will still be usable four years later. But something like a Samsung Galaxy S6 barely has enough battery to make it through the day when brand new and is pretty much unusable two years later even under ideal conditions.

And there's some twenty million tons of gold dissolved in the Earth's oceans. Jules Verne made it the source of Captain Nemo's incredible wealth.

To put twenty million tons of gold in perspective, all the gold that has ever been mined by humans totals up to about 180 thousand tons. To put in another perspective: sure, it's gold, but at a concentration of thirteen billionths of a gram per liter of seawater it's worthless unless you have unlimited time and energy to extract it.

That's the problem with asteroid mining in general. Until the cost of changing an object's momentum goes down drastically it's not worth doing. If Pysche were a 1000 kg block of pure, refined platinum (market price: $34 million) you'd be hard-pressed to retrieve it and return it to Earth at a profit. Which is not to say asteroid mining is a bad idea; but first things first: you've got to reduce the price of interplanetary propulsion by a couple orders of magnitudes. One thing that never happens in a sci-fi asteroid mining scenario is the hero worrying about running out of gas. Propulsion in stories is always practically limitless and free of charge. Real propulsion will never be that good, but it could get good enough.

Comment I'll probably keep it (Score 2) 25

We canceled our cable subscription about a year ago, and while I was OK with it my wife hated not having certain live TV channels. We'd tried Sling, but it was hit-and-miss on the stuff we wanted. Some channels, like BTN, aren't available at all on Sling. DirecTV is only a little more and actually covers the live programming we want.

Make no mistake, the launch was rough. I don't think they allocated enough hardware or bandwidth to handle their initial demand, so streaming cut out constantly. It's finally getting to be pretty solid, though, and I'd much rather pay Sling a few bucks than have anything to do with Comcast.

How much thickness do you think the extra outer layer of plastic adds to the phone? If it has to be more than a millimeter I would be surprised.

Personally, I think it has more to do with the fact the lithium ion batteries have a finite shelf-life than it does with thickness. That means in two years you need a new phone even if you never added any software to it and managed the battery recharging perfectly. Even if the phone had been sitting in a box all that time it'd have significantly less battery life.

The patterns were a mishmash of unrelated structures that were as misleading as they were illuminating.

This pretty much describes the state of every branch of science after a major influx of new data. Just look at the maps of the world produced after Europe became aware of North America. Early maps sometimes show California as an island; and it's not because the cartographer is stupid; he just put the data at his disposal together into what was at the time a plausible conjecture. And in fact the problem might not even have been that he was ignorant. He may have misinterpreted some of the (at that stage) imprecise data he had to work with.

New information confounds. The detection and resolution of conflicts in data is arguably what science is.
