Comment Re:Resistance and temperature (Score 5, Informative) 133

The application I can see is stronger magnets. Right now the superconducting magnets we have are limited by the amount of current they can carry before they start misbehaving. The crappy part is that while we have superconductors which work at liquid nitrogen temperatures, they can't carry a whole lot of current. This leads to MRIs and NMRs using liquid helium cooled magnets which cost a ton of money to maintain. If this material can operate at LN2 temperatures and give the current density of the liquid helium magnets, they will have an amazing product on their hands.

Don't forget this. http://apps.who.int/medicinedocs/en/d/Js6160e/6.html Look at table 4.3. The only markets that matter are the US and western Europe. Everywhere else is peanuts in comparison. The US, Europe and Japan collectively pay for the vast majority of the world's drug R&D through both government grants, venture capital and big pharma research.

Comment Re:Public Funds (Score 1) 116

Let me introduce you to the Bayh Dole act. http://en.wikipedia.org/wiki/Bayh%E2%80%93Dole_Act Before this act, all IP generated by federally funded research was assigned to the federal government which in essence put it into the public domain. The argument comes down to this. Before Bayh-Dole, most research likely to result in profitable products was conducted in companies and the results of the research were kept as trade secrets. After Bayh-Dole, we have much more research being conducted in universities and non-profit institutes. You need to publish your results in order to secure more funding, but the products of the research are assigned to the schools who license them. These licenses in turn fund the schools. Bottom-line, returning to public domain for federally funded research would "close source" research and probably stifle innovation.

My god could you imagine the heat dissipation of a 64 core alpha processor. I had a desktop with an EV7 in it. That thing was a space heater. I just looked it up. The spec was 125W for that thing.

Comment Relative EM radiation strength (Score 1) 627

The thing that kills me about this "WiFi allergy" business is that it is a recent phenomenon. For the last 100 or so years we have been surrounded by much stronger EM radiation. Your typical WiFi card/router outputs about 30mW. Average cell phone of today is less than 1W and typically much less. Typical radio communication gear can be from 5W to 1.5kW. Broadcasters can go up to 50kW. Radar transmitters, not including the gain of their antennas, can be in the low megawatt range. Even when you account for the drop in irradiation intensity due to distance on these powerful transmitters. Think of an airport. Think of how many people a day go through an airport. Now think of the radar intensity of a 1MW transmitter at 1 mile(inverse square law). You get a whopping 300mW/m2, but this is still much less than the exposure limit of 10mW/cm2 or 100W/m2. Now put think of the intensity of those cell phones and WiFi cards. If this allergy to radio existed and was present in even a small fraction of the population we'd expect to see people suddenly come down with symptoms every time the approached any of these large transmitters. Even if you absorbed all of the radiation it would still be less than what you would get from radar.

Oh yeah and there is one more source that we are surrounded by all day every day. It is nearly impossible to escape. The 60Hz radiation from the power grid.

Comment Re:He is not being a hypocrite (Score 1) 340

This is what I don't understand about the "but they aren't embryonic so its ok" argument. Thats not how science works. We didn't go back and forget how to reprogram embryonic stem cells and then relearn how to program iPSC. We used all the data from the old embryo destroying techniques to figure out how to use them. In essence, you are benefiting from the destruction of embryos.

Comment Re:my brother installed some stuff on 3.11 (Score 1) 169

I remember all of this as well. My first experience seeing the web was at the JPL open house in 1993. The pages they had loaded up were JPL, NCSA and CERN. I remember my first thoughts were its like gopher but with inline pictures.

I'm sure everyone wants to forget the pain of the old days too. Installing trumpet stack on your Windows 3.1 box and then struggling for days trying to figure out what was going wrong. Oh and don't forget having to install the 32-bit extension on to old 16-bit Windows so that you could use NCSA Mosaic/Mozilla.

Came here to say this. Reusing names within the same field is fail. If you cannot be bothered to google a term to make sure it is relatively unused, you are lazy. When you work in electronics, computers or communication and don't even realize there is a protocol called Telex already....

Comment Re:Civil and criminal liability (Score 2) 405

I wonder is the FBI could subpoena a critical control system say a Siemen's SCADA controller that had been hacked. If this control system were used to control a machine capable of causing grievous bodily harm or death, would the FBI not be negligent? If the FBI took a server legitimately housing an e-commerce site containing customer data, would that be considered a data breach under California law?(FTCA torts are determined under state law not under Federal)

The FTCA specifically allows claims based upon negligence to be brought against the Federal government. However, you are correct that this liability is limited by the exemption you have posted. I don't think that any reasonable person could suggest that if data were stored on a server at Google and distributed over an entire datacenter, that the entire datacenter could be seized. That exemption gives Federal employees the leeway to search a house they reasonably believe contains a fleeing suspect. It does not cover something like seizing all the cars on a block because one contained drugs. No reasonable person would suggest such a ludicrous argument in that case nor should anyone suggest that since these 100 or so servers are in close proximity in a data center they may all be seized.
