Comment 'Choices' codeword for lack of solutions (Score 2) 144

If they had an electrolyte that worked in this application they wouldn't be talking about all the possible choices. They would tell us what worked.

"For this solid electrolyte, we have plenty of choices. We can use gelled polymer electrolytes, made by swelling a polymer matrix with an electrolyte solution, or we can solidify ionic liquids by adding polymers or silica nanopowder. This nonleaking design, together with a virtually unlimited number of charge and discharge cycles, means that our supermicrocapacitors will likely outlast all other electronic devices on the chip. Such long life will be particularly useful whenever it is inconvenient or dangerous to open things up to replace a power source, as in pacemakers, defibrillators, and other medical implants."

Electrical and magnet fields occur in 3 dimensions, not one. They can talk about the gap between the fingers of their layout, but their effective average gap in 3D is probably closer to PI*center_distance/2 which gives a lesser result for the expected capacitance. Their max voltage with a given electrolyte is limited to the closest edge, but that is not how a physicist would compute expected capacitance.

"Just"? Hydrogen is very inefficient to compress and not very useful uncompressed. If you react it to store it, then you have thermal losses going both directions and because hydrogen has an atomic weight of 1, anything you mix it with for storage purposes will have a relatively low energy density. Over time it turns even the hardest steels brittle and is a pain to handle. And then there is the fact that it is an explosion hazard. There is no "Just" when it comes to hydrogen.

Comment I asked Belkin about a similar issue (Score 1) 48

I attempted to report a similar issue to Belkin last October via their forums and asked if they would be providing an update. They not only deleted my post, they deleted the account that I had to set up to make the post. I took that as an emphatic 'NO', there would not be an update.

Comment IPs often assoc with multi-homed hosts (Score 1) 31

The problem with IPs found this way is that they are often associated with hundreds to thousands of web sites, and the bad actors shift between these backends rapidly. For instance I have seen cases where there are a few Wordpress generated sites out of thousands being used to host malware configs and updates at a single IP of a low-end hosting provider. I have seen many similar instances where the IP was associated with AWS. The most precise way to blacklist sites like this is by hostname and not by IP.

Comment Computers are just components to Navy (Score 3, Informative) 192

The Navy purchases computers as parts of much larger systems, often ships. These things get assembled and their expected lifetime is much longer that the technology cycles we enjoy outside of their domain. Refit schedules are not driven by the computers on board but rather by much larger, more expensive and longer lived components like diesel motors. The Navy is just in the last couple of years starting to move some of their onboard computer systems to what they refer to as "Carry On" components. There are probably ships in the fleet that have 25 year old electronics on them because these components weren't ever expected to be replaced.

Loan defaults have nothing to do with the cost of college. It is almost the opposite, it is the availability of the loans in the first place that have raised the cost of a college education. The government has effectively made all of this money available without putting constraints on credit-hour costs or how the universities actually spend the money. Universities are money spending machines, you give them money and they will spend it. Using loans in an attempt to make college more democratically available completely backfired. This was a foreseeable economic disaster.

Comment Re:Why? (Score 4, Informative) 1032

Until 1987 or so, the cost of college in Texas was extremely low. I was very frugal and my entire expenditures for tuition, room and board from Sept 1981 to Sept 1982 was $2500. At the time minimum wage was $3.35. A person could work a part time job (15 hours a week) and pay for this. I'll bet that most of the tuition collected by the University of Texas at the time was directly from the students or the student's parents with grants and scholarships coming next and student loans running a distant fourth. As the government made student loans more available in order to make college more available the government accomplished the opposite of the desired effect because the government ignored basic economics. Making more money available affects spending at the universities which affects costs. Universities are money spending machines. The University of Texas now has more than double improved square footage that it had in 1981. The buildings are nicer too. But the size of the student body has not increased proportionately. The university simply spends more on building and maintenance. Far more than it spends actually delivering an education. Under the current system your hard earned tax dollars are going to build monuments rather being effectively used to educate. We had a system that did the opposite quite effectively and we could have that again. Instead of being cheap with your tax dollars you should be angry with how they are being spent now.

Comment Staff notoriously underpaid (Score 1) 234

Many of these people were staff, not faculty at CMU. As a former director of a University research lab (otherwise known as a software sweatshop) I can attest that staff at universities tend to be grossly underpaid. Universities resist any staff making more money than their lower paid professors (think English, History, etc). It is all about politics and ego. A little help from LinkedIn shows some of Uber's employees former titles at CMU: Sr. Research Engineer, Graduate Student - Interaction Design, Commercialization Specialist , Senior Information Systems Specialist, Research Assistant, Senior Commercialization Specialist, Research Programmer, Graduate Research Assistant, Student, Research Assistant, Graduate Research Assistant, ...

The original paper mentions the red-shift and spectral similarities of 3 of the observed quasars without mentioning the possibility that they may be the result of gravitational lensing by the fourth object and could possibly be millions of light years behind the 4th object.

With 573 episodes to pull from and even more studio tape they have sufficient material to clone his voice. All they need is some other anonymous slob to read through all the hours of old material which they can do for a lot less than 14 million dollars. The question is will they?

Comment Re:Lie detector tests are fiction (Score 2) 246

The polygraph as used by the DoD and related agencies has very little to do with 'detecting lies'. It is MUCH more a grueling personality test in the guise of a lie detector test. It may use the same equipment that local law enforcement uses, but the intent of the session is very different. The #1 key to passing is to not punch the examiner in the nose. By the end of the day this is more difficult than it sounds.
