not very conductive. You can used various PeDOT polymers inks but you're best best is usually to go with metallic nanoparticles. Those aren't too great because they limit the number of substrates you can use due to required post-deposition processing (annealing mostly, to make them conductive). We also managed to print nanowires and carbon nanotubes. Those are extremely conductive and require little post-processing. In fact, we did most of our work on paper substrates.
Or if you've got $50K to spare, checkout the Dimatix material deposition printers. I spent 2 years on one in a printed electronic lab at Stanford. You'll need access to a chem lab to get research-grade printable & conductive polymers :)
I like social and other vanity-in-appearance like companies. I think we are quick to discard them as trivial and non-beneficial, and quick to forget that they further accelerate the dissemination of information whether that information is useless (e.g. most memes) or fundamental to human development (e.g. arab springs). What does bug me is that a lot of the "innovation" in social is similar to the "innovation" in finance, where it's a bit of a stretch of the mind to accept that the "innovation" is truly beneficial for society at large, or that the utility derived from it matches the utility that could be derived from employing the technical talent behind it to other ends. We need a balanced world, but we also need to push the "human race forward."
I was psyched about contributing to this awesome project so I immediately checked out the core. Then i saw it's written in php........... never mind :(
I'm a scientist (certified for radioactive & x-ray research) so I totally hear the point to be made regarding something not being a fact until a thorough investigation has been done on the matter. However, the fact that electromagnetic wave cause harm or may have secondary effect in some people is not that far fetched and should not be discarded as "is anyone really still concerned". We just don't have a sample size of individuals troubled by it that is sufficiently large enough to prove it. The majority of us may show no signs of harm; yet I know of at least two people that suffer from electromagnetic hypersensitivity, probably resulting from having 30 different wifi signals crossing their walls day & night for the last ten years. Indeed, I don't believe cell-phone tower signals at long range are really the cause. It's more likely to be the high concentration of wifi signals inside of apartment complexes. And even if the exposure intensity is a matter of square root with respect to distance from source, you can get significant exposure when you increase the number of source or the relative average distance you are from them. So no, electromagnetic waves is nothing to sneeze at. If you think so, why don't you go sleep every night in a tiny room with 15 wifi routers on and a couple of cell-towers directly above your head?
There's certainly a lot of truth here. However, Mark Zuckerberg built the company to last. So I think it's unlikely that it will completely be marginalized.
Regarding the Zuck = Jobs. Absolutely not. Yes, they are both product people. But Mark Zuckerberg does not have the same aura or doesn't necessarily have the same depth of intellectuality that Jobs (college dropout or not) had. When I see Mark Zuckerberg, I think more of the Bill Gates or our time than an artistic genius with deep root in counter-culture lifestyle.
is he right when he says that Facebook will eventually be forced to release personal data to its users? Would it be a market constraint? If so from whom? Or would be a legal constraint?
haha it's funny you mention that. I was thinking to myself 1 min ago that technically it's not a failed launch but an aborted one. thanks for pointing it out!
There are housing development underway between south San Jose and Gilroy, but unfortunately, the jobs are not located there. While that may remove some pain off of the real-estate market further North, opening more development south of San Jose won't do much good if all the jobs stay in the Palo Alto / Mountain View/ Sunnyvale/ Santa Clara region.
The only weekend when casinos did not make a profit, in the entire history of Las Vegas, was when the annual U.S. statisticians conference was organized in Las Vegas :)
I recently had a chit-chat with a 5th year phd friend of mine in front of the stanford bookstore. We both did academic research, and both know all too well the incredible frustration of tech not-having full penetrated academic research. If ever you'd like to work toward making research faster, reply to this. We could think about a couple of things and start cranking out some solutions.
