So why is it swipe&sign vs. chip&pin, why not chip&sign? This would make it near impossible to clone cards but still be more secure under audit (i.e. not subject to easily stolen PIN). Even chip and nothing would probably be better in practice than swipe and sign.

That doesn't even seem to make sense. Even with swipe and sign a card doesn't really "work" on two different networks. Does anybody know how this regulation really works?

I think it does always require measuring proficiency at the end. Otherwise how do you know if you are educating?

That being said, it is easy to create a test that will rank students, but extremely difficult to make a test that will measure their proficiency. And making one that is resistant to cheating (e.g. memorizing answers from previous tests) is even harder.

Current grading is generally not even based on level of proficiency, but on level of coverage. You get a good grade if you can demonstrate skill in all the topics covered. The level of proficiency expected on those topics is often not well defined. Also this leads to what the thread root comment is complaining about, where the class is taught as if everybody is going to achieve proficiency in all topics, even when that is known to not be happening. Is it better to teach a set of topics for which it is known the median student can achieve satisfactory proficiency, and then measure proficiency? What does the letter grade mean in such a system? Does in refer to proficiency or coverage?

Nominally this reveals the underlying problem being grappled with in education today. If you get down and honestly measure student proficiency, you realize that only the top 10% of students were actually learning what they were supposedly learning. This makes it really hard to construct a coherent overall sequence of education because you cannot assume that most students have mastered topics covered in previous courses.

So fund the science. Forbidding regulation is just beuracratic stupidity that will get people killed. My impression is that a lot of regulations don't have good science to back them up because the science costs money and hasn't been done yet, and EPA has to make a rule even in the absence of good science. Are you somehow surprised that they would err on the side of public safety when the science is inconclusive? You do realize that this stuff actually maims and kills people right?

they're done professionally

Um, now they can begin professionally. I certainly hope that they were trying to get tenure so that they could educate the next generation and improve the knowledge in their chosen field. Who gives a hoot where you live if somebody is paying you to improve worldwide knowledge?

You do not appear to understand what he is getting at. In the case referred to in the original article, the credit card info stored at one company was used as proof of identity to another company. i.e. your credit card can be used to identify you uniquely if you only use one credit card. On the other hand if you use pre-paid limited-use cards, this doesn't work. This seems like a general benefit to prevent companies from cross-tracking purchasing habits. But the interesting thing here is this case shows that it also provides additional protection against identity theft-type attacks using your credit card info. Basically because you don't have unique credit card info.

But really that godaddy would give control of your account to somebody that has your credit card info is outrageously stupid on their part. Credit cards are a payment method, not an authentication method. The bank will only eat the cost of payment fraud. This was probably some undertrained phone support person thinking there was no other way to get this guy's account access back, which is ludicrous since he probably has ICANN contact information recorded. They could have hung up and called him back using known-good contact info and the whole scheme would have fallen apart.

As others have said, the lesson is don't use godaddy since they are so "customer-friendly" that they are insecure. This just makes me glad that I moved away from godaddy a while ago.

Sorry the Centrifuge Accomodations Module was cancelled. I consider this emblematic of the space program having absolutely no intelligent direction. This module should be at the center of te ISS mission, since the station's primary direct scientific product is study of biology in space. Also one of the most unique aspects of space is microgravity, i.e. low, controlled acceleration in a variable-rate centrifuge module.

or Snowden-Obama: 1 Military-industrial Complex: 0.9. Unlike some other posters you do appear to have some inkling that democrats, including Obama, can't just do anything they please and still get elected. A lot of the things left-leaning independents would like them to do don't get done simply because distortions of those actions could be easily used to whip the ignorant masses into foaming fury with a few deceptive commercials. It turns out keeping power away from the dishonest madmen is pretty tricky with an ignorant electorate. And I totally agree voting reforms would help, but until then...

disaster? Because McCain starting a war with Iran with one hand and letting the country slide into another great depression with the other would have been sooo much better. Amazing how fast people forget reality.

2.4/5/6/7 are more different than you might think. Some of the things that were "added" were already there in a preliminary form and therefore had their names and interfaces changed.

Why is there no remote manipulator robot to do this? Is the goal here to test space suits or maintain a space station?

The space station should have the most advanced remote manipulator system available. Deep-sea work is not done by guys in complex suits, it is done by remotely controlled manipulator robots. The continued dependence on space suits for basic construction/repair/maintenence operation just seems like a bad idea given current remote maniplulation technology.

Once again a bitcoiner doesn't understand that the ever-increasing value of a bitcoin is a primary problem with it as a currency. Nobody is saying its not working out as a great speculative investment vehicle. Currently the fed is fighting deflation like crazy to keep the economy stable. Currency and investment are different things.

Wow, free marketer fail. Regulation has fairly little to do with why I have only one power company. That has to do with the fact that it would be insanely disruptive to run multiple power companies' lines all over the place. Most of the regulation is to counteract this factor driving toward a natural monopoly.

Have you aver heard of H-index. It combines rate and impact (measured by number of citations) in a way that also de-emphasizes one off flukes. I actually tend to compare H-index per year, which is a useful measure of contribution rate. But, that said, there are massive variations between even sub-fields in the same discipline due to different publishing and citation culture.

How would he sign the TOS without a linkedin account? The point is that people are saying you have a choice, but if your friend uses gmail, which you may not even be able to tell if their mail is forwarded, you don't have much of a choice but to be spied on by google. At least with the government your data is not for sale to the highest bidder.
