Comment Re:Energy requirements? (Score 1) 348

The "literal" dark side (that is, the side which isn't currently lit) changes, with a sunrise every ~28 days.

The "figurative" dark side (that is, the side which isn't facing the earth) is fixed.

Since it's the literal one that would be involved in any sort of heat engine, it's possible that you have them confused.

If a person's going the same speed as you a mile in front of you or a mile behind you, you'll never know. On the other hand, if someone is going 10 MPH faster then you, a mile behind you, then they're going to pass you in 6 minutes and then be gone. But if someone's going 10 miles an hour slower then you a mile in front of you, you might be stuck behind them in 6 minutes, and you're going to stay there until one of you makes a turn (depending on passing conditions).

This sort of thing influences peoples' opinions of how fast other people drive.

If it actually *caused* a leak, then yes. If it just didn't work, then no.

Someone being convinced to wear a bullet proof vest by a loved one who feared for their safety, and then getting shot in an area it didn't protect isn't irony. Someone being convinced to wear a bullet proof vest by a loved one who feared for their safety, and then drowning because their vest weighed them down is irony.

And in any case, the "leaked" document is very clearly marked "not classified".

Wait, what are we knocking off? Shooting people? Telling people to pursue a "second amendment remedy" if their candidate doesn't win? Or noticing that when you preach hate and guns, eventually someone's going to get shot?

I bet it's the third one that's the real problem here. Yea. That's the ticket.

Comment Re:so one thing i don't get... (Score 1) 244

You'd buy from it because it was cheaper. The technology to keep the mine running in 2002 was too expensive to keep up with China's prices, but since then the price for the technology has gone down and China's prices (for export, at least) have gone up. Now they think they can be cheaper then China even with CA's labor and environment laws.

But more then that, the China threatened to cut off our supply of rare earth metals, and because they are used in many military applications this really is a national security issue. If I were an investor, I'd bet my money that even if China drops its tariffs back down, the US government will either tax foreign rare earth metals or subsidize their production stateside. Especially if someone donates to the right campaigns.

Comment Re:Premature Celebration (Score 1) 121

It does seem a bit early to be proclaiming this molecule as a new rocket fuel, but it's never too early to criticize the shuttle's SRB's. Not only are they ridiculously expensive and horrible for the environment, but they're terribly unsafe. Seriously, the reason why the shuttle has to be assembled vertically and towed by a huge and expensive piece of custom machinery to the launchpad is because otherwise the SRB's will probably explode.

Now at this point you might speculate that the SRB's are esential to manned spaceflight, but you'd be wrong. SpaceX just launched its eventually-human-carrying Dragon spacecraft using only liquid fuel. So then why do all the proposals for NASA's shuttle replacement have SRB's in them? Because they are *so* expensive that it's politically impossible to lose the shuttle without another use for SRB's.

Comment Re:Ranging from proof of life to first contact? (Score 1) 286

It says that the finding will impact "the search for evidence", which makes me think even you are being a bit optimistic. My bet is on "we have developed a technique that could be used to find evidence that some precursor to life may have been present on a given extraterrestrial body -- or may not, depending heavily on your interpretation of the very ambiguous data this technique will provide."

An upgrade to a PS4 now would cost huge amounts to develop, would have to be sold at a loss, wouldn't offer an immediate and significant improvement in graphics or gameplay, and would be followed by a new offering from Microsoft and Nintendo fairly quickly. And most of all, the success of the Wii showed that you don't need the biggest processor to make money.

Personally I see two paths to the next generation. One is a game that can't be made 3D without either a hardware upgrade or a graphics downgrade, combined with a super-secret new console that we don't hear about until it's almost on the shelves. Obviously won't happen until 3D TV's are common. The other is the Wii being pushed to slightly above 360/PS3 hardware levels, with a price similar to current PS3/360 prices. The former path is probably more likely and will result in a higher-quality next generation, the latter would probably deal a serious blow to the nextgen Microsoft and Sony offerings. I suppose if neither happens in the next few years a more typical generation movement would happen.

Well that's the thing. With all the drama surrounding their releases, 'he' stays in the news. As long as he's there, it would be quite hard to kill him and not have everyone know what you've done. If they lose the drama and make every effort to become invisible, on the other hand, he can disappear without comment. Of course, the 'insurance' file also probably helps with that.

Comment Re:Who decides what the definition of "planet" is? (Score 1) 257

I think the editor is mixing up "impetus for discussion about the definition of planet (which ended up excluding Pluto)" with "reasons for the final definition of planet (which excludes Pluto)".

What actually happened was: we discovered Eris, and the IAU said "huh. It seems likely that there are hundreds of objects large enough that we'll have to decide if they're planets, where before everything we found was clearly either a planet or an asteroid/comet. Not to mention all these planets we're finding around other stars... We need a good definition of planet to go forward with." The final definition agreed upon excluded Pluto.

What the editor appears to believe happened is: we discovered Eris, and the IAU said "huh. This is bigger then Pluto, so either both are planets or neither are. We don't want to increase the number of planets, so lets go with 'neither'."

At least, I don't see any reason why someone might think an adjustment to the size of Eris would cause a reconsideration of Pluto as a planet unless something like the second was what happened.

Comment Re:Why are phones special? (Score 1) 262

Mostly because car manufacturers don't all own gas companies, or have exclusivity agreements with them.

No, really. If they did own gas companies, they would lock their own cars such that they could only use the right brand of gas, and then they wouldn't care about how much fuel got wasted since any drop in customers due to bad MPG would be made up for by increased fuel sales. Then we'd have reason to hack in, to remove the station-specific locks, and to correct the fuel injection amounts.

As it is, it's in the manufacturer's best interests to get those as good as possible on their own, and they do a near-optimal job. Nothing to fix.

We'll see if this continues once actual computer interfaces in the passenger compartment become commonplace, however. If they decide to try to prevent us from adding our own applications and similar, I'm sure we'll see just as much jail-breaking for cars as we do for phones.
