Comment Garbage Sites, Garbage Passwords (Score 1) 276

It's interesting that all of these "onoes errybody using the same password errywhere" stories fail to point out that the junk logins required by almost every site for the purpose to collecting ad demo data essentially feed weak passwords to black hats. This has trained many people to use the same password everywhere, since no sane person will maintain and memorize separate passwords for dozens of sites, many of which they may just utilize for entertainment. Combined with the weak security even major players (c.f. Sony) have been shown to use, this is now a bottomless cornucopia of id theft data.
Since it's well known that a large proportion of user demo data entered along with these logins is also junk, the smart guys use bugs and IP tracking, and profiling of various kinds to collect this data now anyway, so it's not even useful to have local logins for that purpose. It's time for sites to Just Say NO To Junk Logins...

Tidal interaction has nothing to do with it. Actually, the Earth's magnetic field would likely be stronger without the Moon since tidal interactions have transferred angular momentum to the Moon and slowed the Earth's spin over geologic time.

Mars' core has likely long solidified given its small size and Venus rotates very slowly, which is why neither of them has a significant active dynamo.

Comment Margin of error (Score 4, Interesting) 449

It seems very scary that on an aircraft with everything working but the airspeed indicators (and I understand that those are very important), after more than 3 1/2 minutes the aircrew was unable to prevent the plane from hitting the ocean. This was a state of the art aircraft. Makes you wonder how many close calls there have been that luckily didn't result in catastrophe.

The project is certainly threatened by Chrome, and has no chance to beat it given that it's Google's own browser, so these efforts to ride along on Chrome's publicity ultimately are doomed to fail. As long as Google commits resources to develop Chrome anyway. The issue is that if you have the skills to produce a browser that is on a par with Chrome, why would you not take a big salary to work ON Chrome.

I personally think Firefox should focus on the privacy/security aspects of the experience and make it clear they are the anti-Chrome aka extension of Google's tentacles onto all aspects of your online existence. I honestly have no idea what the strategy is at Mozilla right now, and I suspect neither do they. Trying to be some kind of cuddlier but much slower version of Chrome is very 'wut?' to me.

Comment Re:Nuke power (Score 2) 483

Exactly. I'm not "scared" of nuclear power, I'm an engineer and I understand the concepts of risk and failure mode effects analysis. The problem is primarily management failures in most of these high-profile accidents, as summarized by the poster above. There is no way to eliminate those on long enough time scales because human beings make mistakes. The problem with nuclear power is that the catastrophe scenario is very, very bad, and the timescale to react is very short. The latest update from Fukushima is that according to simulations based on the data they have, the Unit 1 reactor began melting down within 16 hours after loss of core cooling.

My feeling from reading some of the responses from people who are in favor of nuclear power is that for some people it reduces to an attachment to the technology. It's pretty cool to have the ability to split the atom to generate power (even though it's ultimately just boiling water). There's a visceral pride we feel in being able to harness something inherently very dangerous. Until it gets away from us.

Comment Where is all the water going?? (Score 2) 664

So it seems clear at this point that all three of the damaged reactors are leaking water, meaning, logically, that the containments are breached in all of them. Building 4's spent fuel pool also is suspected to be leaking. Where are the tons of water they are pumping in every day going? The turbine building basements so not have infinite capacity, and that much water won't evaporate at any speed from inside underground spaces...

Comment Re:Flight Recorders are Sooo 20th Century (Score 2) 218

What happens if (I know this never happens in real life, LOL) but hypothetically, what happens if something interrupts the communication from the plane, say for example when it is upside-down in a raging thunderstorm plunging towards the ocean surface?

You would still need a backup flight recorder. The advantage of the inflight system is that you might obviate having to find wreckage in a case like the Air France flight, but in exchange you would have to be constantly storing telemetry data from thousands of commercial flights a day; this would cost more on a yearly basis than spending $20M to send bots to the ocean floor for the once in a generation crash like this.
