Comment Re:Why? (Score 1) 433

PhDs, in the sciences at least, are not the same as masters courses (or MDs?) in that PhD students get funded by grants. Typically the grant covers the costs of the course and something like $20,000 for living expenses. Although this is a tiny amount of money, the students typically get subsidised housing so it doesn't work out badly at all. I've never heard of a self-funded PhD student.

True, but you also have to consider the value of your time. For experimental physics, the mean time to complete a PhD is around six years, and most people in that position could probably earn 40-50k straight out of school (not doing physics, of course). So the opportunity cost is something like $120k + interest on student loans from undergrad.

As for self-funded PhD students: I've never seen one in person, but I hear they exist. And I hear that the entrance requirements are much looser (which is funny because most PhD students should have at least a partial research assistantship after the first year or two)

Nah. There's plenty of talented people applying to med school. As an example, medical school applicants who get in through affirmative action have no worse outcomes that other medical students, despite having generally lower grades. Thus, the supply of doctors can be increased without compromising quality. The real problem is that the AMA has not put in a new medical school for over 30 years, despite the population doubling in that time. They want to keep the supply low to artificially inflate physician salaries.

As someone who has watched from the sidelines (I TA'd a series of physics labs for pre-med students, who. just. had. to. have. that. A.), this sounds spot-on. Med schools make applicants jump through tons of hoops (one of those hoops is getting straight-A's in physics) in order to reduce the size of the applicant pool. The difference in patient outcome between a doctor who earned an A and one who earned a B in $PHYSICS_FOR_PREMEDS would be completely negligible. Yet, it allows medical schools to cost-effectively reject a large fraction of applicants and discourage many more from even applying in the first place.

DNRTFA, but in Japan there would be a market niche for this kind of hardware, maybe to use with a stored value card of the kind that is used to ride the train. There are many establishments - cafes and small restaurants - that will not let customers plug a computer on the account of the outrageous electricity bills they believe they will incur.

That doesn't make much sense... using what I think are reasonable estimates, 10 outlets * 100W per outlet * 10 hours per day * 360 days * $0.2 per kWh only works out to a few hundred dollars per year. Surely any one of the electrical appliances (or lighting) in a small restaurant or cafe uses more than that. On the other hand, I could see them wanting to discourage people from occupying a table all day when other customers need seats...

Iran won't blockade the Straight of Hormuz.

They don't have to. The shipping lanes in the Straight of Hormuz are in Iran's territorial waters, which means they get to make the rules about who's allowed in. If Iran fires an a convoy escort, that's not an act of war. If the escort fires back, it is.

Committing an act of war would give Iran's few allies all the cover they need to continue their support.

Basically, they have us by the balls.

I think that a better place to start would be strict enforcement of existing laws: Drivers in the LA area have been noticeably more well-behaved (especially near Malibu, where this attack took place) since this widely-publicized trial--The realization of possibility of loosing one's freedom has a tendency to focus the mind. Treating extremely aggressive driving as assault (look up the legal definition of assault), and better cooperation from law enforcement officers would be a good place to start. If that doesn't work after a reasonable trial period, I would be open to increasing penalties.

And just to head off the predictable responses at the pass: yes, cyclist need to follow the laws, too. But as much as I hear drivers complain, I can't help but notice the double-standard: speeding and "california rolls" aren't illegal when motorists do it. Yet, somehow, a cyclist flying down a hill at ten over the speed limit is still obstructing the flow of traffic.

Your GPS also receives data at a rate of about 50 *bits* per second. Good luck finding a voice CODEC that doesn't need at least 20x that bandwidth to make you not sound like a robot.

Also, the CDMA chip sequences used by the GPS system effectively act like a lock-in amplifier, which increases the signal-to-noise ratio tremendously.

IANAL and this is not legal advice

I understand that civil court does not have the same strict rules about how clear cut the case must be, but...

I hate to be an ass, but I don't think you do. Civil court is all about perponderance of evidence, not reasonable doubt. If I claim you infringed my copyright because I saw my copyrighted work being uploaded from your router's IP address, you saying, "But it could have been anyone!" doesn't cut it. If I provide evidence (no matter how superficial or circumstantial it might be) that tends to point to your guilt, and you provide nothing, then I win. I don't have to show that the file is the actual movie (although it would help my case to do so). In a criminal case, those might not be terrible defenses, because they introduce reasonable doubt as to whether any law was actually broken and as to whether you were the person who broke it.

To win in your example, you'd probably need (at the very least) to come up with a plausible explanation for how and why someone else was using your IP. Even then, it comes down to which legal theory does the jury find more convincing and/or likely: the plaintiff's (that the defendant infringed copyright) or the defendant's (that s/he didn't--but that the infringement happened with his/her ip--and that some unknown person somehow accessed the defendant's network for the purpose of infringement). All I say is, "good luck with that one."

And just to be clear: I'm not arguing that it should be so easy for the plaintiff to win these civil cases, just that it is.

And not only doctoral theses. My undergrad university (and I'm sure many others) prohibited turning in work that had been originally done for a previous course. It really doesn't seem that unreasonable: if the courses are so similar that you can reuse substantial parts of your prior work, then why should you get course credit? You don't usually get credit for taking a course twice (yes, yes, advanced topics / independent study / etc. aside)

Comment Re:Volt is not a measurement of power (Score 1) 188

(Physicist here) That's correct, though in practice most powered hubs will let you take 500 mA per port without negotiation, and the newer ones that support the USB 2.0 charging spec will let you take even more (~1.8A if you touch the data lines just right). The voltage is also allowed to sag, IIRC, 5% and still be in spec, so assume 4.75 V. That gives a power of 4.75 V * 1.8 A = 8.5 W per port. Times 30, and you could have around 250 W of cooking power. Some of the cheaper hubs (which don't follow the USB spec rigorously) will even allow you to take all the available current through one port, instead of cutting you off at .5 A per, like the better ones do; so, a cheap 4-port hub might have 2 A available on any one port, but not on all simultaneously.
