Comment Re:No Backup? (Score 2) 72

I read that as "landing *system* failure". If a plane's engines die it can glide; if its landing gear fails to deploy it can still perform a controlled belly landing; if it's approaching at a bad trajectory it can take another go-around.

Starship has redundant landing engines (at least one prototype landing test failure was because it wasn't prepared to *use* the redundant engines; lesson learned...), but unless they're keeping better ideas secret, the current backup plan if a trajectory goes bad is "fall in the ocean, tip over uncontrolled, and hope not to explode", and the backup plan if a tower catch fails (they're basically putting the landing gear on the *ground* rather than on the vehicle!) is "try again until a slim propellant margin runs dry, then fall onto concrete".

If Starship works at all, this shouldn't be a long-term problem, I think. They'll have loads of opportunities to iteratively improve the system once they're flying it unmanned every week. They may never get to 1-in-a-hundred-billion commercial aircraft risk levels, but they'll be under the 1-in-250 levels that astronauts tolerate in no time.

Comment Re:Fuck Tipping (Score 5, Interesting) 262

I remember reading about an experiment where they had servers behave (at random) either happy and cheerful, or abrupt, rushed and unfirendly. In both cases they performed their job the same. The result was that the "friendly and cheerful" staff were tipped less on average. The theory was that people perceived the cheerful and friendly staff as being less deserving of a tip because they were clearly enjoying their job, or were having to work less hard.

It is akin to the locksmith paradox. If you have a newly trained guy turn up and take an hour to get into your house/car, you feel like he's worked hard and deserves his $100. If he has 10 years experience and does the job in 5 minutes because he knows exactly what to do, many will feel cheated when they hand over the same fee, despite getting an objectively better service, because they perceive that he didn't work so hard.

How is this different than spy apps?

A thief may steal property but a liar may steal reality.

Pair two technologies we know already exist. They have shown us video that has been altered that most people didn't catch like Obama making statements he didn't make just used his millions of audio data to make a false statement and edit lip movement to match.

Now pair it with Google's assistant which can book appointments and interact in a way undetectable by most people. Good thing they don't have 15 years of you speaking, enunciating, divulging personal information over the wire...what you've been using Google voice for a decade? Google fiber too? OMG and your Gmail? Well heck mixed with customized video, your voice and knowledge of virtually everything you've said for two decades they could literally call your mama on Skype and tell her you'll be there for dinner.

So what's the big deal? Reality has effectively has been stolen from you. Your choices, opinions, and personality are based on lies and that makes you what they want to make you.
 

Finally, a good reason to have an existential crisis.

Right, replacing infrastructure which can output a predictable amount of energy 24/7 with power sources which fluctuate massively depending on environmental conditions ... that doesn't change anything at all.

We're replacing it with a power source that doesn't make environmental conditions fluctuate, moron.

Any polyatomic gas is a greenhouse gas. If it's airborne and has three or more atoms, it qualifies.

Low energy infrared photons (like those emitted by a body at 300K) can cause bonds to bend side to side in a flapping motion.

Oxygen and nitrogen are diatomic molecules. They can stretch, but there's no way they can bend because there are only two atoms. So they're transparent to IR emitted from the ground and are not greenhouse gases. Molecules that can bend need three atoms or more, like carbon dioxide, which gets hit by an infrared photon and moves like a bird flapping its wings before reemitting it. H2O is also a greenhouse gas but its long term atmospheric concentration is stable over the long term and doesn't rise year over year. Methane is a potent gas because it's tetrahedral and its single bonds are easier to flex than e.g. the double bonds in CO2.

HFCs and CFCs also have tetrahedral shapes with single bonds, but they're more potent greenhouse gases than methane, because the fluorine and chlorine atoms distort the charge concentration and give the molecule a dipole moment that makes it better at scattering photons. They also provide it with more possible bending motions.

I'm not sure why this article is talking about illegal fluorotrichloromethane being a greenhouse gas. It's illegal because it destroys stratospheric ozone. Gram for gram, sarin is an extremely potent greenhouse gas, but that's not why it's illegal.
