    Spam will continue to disguise itself as legit email. You can try to filter it out and set more strict filters but catching legitimate mail is far more likely to happen. In the end, you have to make a trade off and practically accept some spam.

  3. Good Iternships on Summer Internships - The Good, and the Bad? · · Score: 2, Insightful

    Many companies are willing to take students iterns for the summer. I know of a couple of iterns at Sandia National Laboratories that did an amazing amount of software development. Local companies often have openings and are willing to work with people. Use your imagination and don't just try big name projects.

  4. Re:Any More? on Circuits Better with Purer Nanotubes · · Score: 1

    Expect organic electronics to start replacing inorganic (i.e. silicon) quite soon. OLED displays are already on the market. Polymer solar cells that look like a big clear plastic tarp uses a special nanotube called a "buckeyball" (aka C60 carbon nanotube, buckministerfullerene, fullerene, etc.) to help with the light conversion process. The technology is here and now. Manufacturing issues are what's holding everything up. That, and the fact that organic semiconductors are p type semiconductors only (there is no n type).

  5. Re:That's a neat graphic in the article... on Circuits Better with Purer Nanotubes · · Score: 1

    It's a representation of how one might use carbon nanotubes in a circuit. Since they have mobilities far higher than inorganic material (i.e. copper and gold) they are nice to use as line. The greyish lines on single nanotubes functioning as lines (yes a single molecule). The orangish stuff on the side is represented by a film, most likely spin casted, that is either a conducting polymer like poly-aninline or poly-thiophine or a silver/gold based film. The technique for depositing would be similar to the photo lithography techniques currently used for inorganics although theorectially the smallest gate junction could be 10x smaller. On another note, multi-walled nanotubes (think a bunch of nanotubes glued together at various angles) make excellent t-junctions and node and will probably be used in the future.

  6. Re:Mars exploration on More New Details on NASA's CEV Launcher Studies · · Score: 1

    NASA has been like this for years. There are several private companies that are more than capable of developing a system for NASA, one that would be fully reuseable, have specs similar to NASA's and cost dramatically less than what the shuttle costs and what the CEV will cost if it goes into production. However, NASA isn't quite ready to commercialize space yet. I think though that we are seeing the beginning of space privatization. Once Scaled Composites finishes developing the SpaceShipTwo, private spaceflight will start to leapfrog past NASA, esspecially with Bigelow Aerospace's inflatable space station modules.

  7. Re:Experience is key... on How Important is a Well-Known CS Degree? · · Score: 4, Interesting

    Experience is definitely the key, and many times more important than a piece of paper saying you know what you know + 20%. I know of several highly succesful people (including some CS folks) that are still going through college, yet they get regularly hired by companies to do high end jobs and are picked above people coming from prestigous universities. A degree is one thing, but experience serves as proof that you can do the job and are worth it. If possible, start building up your job portfolio now. Intern with a company or program on the side. That will make you a far more favorable candidate in the future than any piece of paper will.

    You can't put them in a vacuum without serious redesign. Keep in mind that in order to store suitable quantities of hydrogen, the tanks are pressurized to several THOUSAND psi. Taking away a stabilizing pressure that is pushing back, like the atmosphere is trouble, big trouble. Not to mention that it is to costly for a proposed safety item that does no good.

    Funny thing is that the best, most efficient way of generating hydrogen from water hydrolysis is through WIND power....... Turns out that the company Hydrogenics already has an industrial grade hydrogen converter from wind power already on the market. Several of these are enough for an entire gas (well, now it will be "fuel") stations to meet demand.

  12. A safe viable alternative on Could Nuclear Power Wean the U.S. From Oil? · · Score: 1

    Nuclear power is a safe viable alternative. Most reactors in the United States are 2nd generation reactors. They still have some manually controlled safety systems, and the efficiency is actually quite low. On the other hand, today we have a set of 3rd and 3rd+ generation reactors ready for implementation, with even safer more efficient 4th generation reactors well into development. They also have a smaller footprint, resulting in reduced cost. Everything is automated, required only a small tech crew to stand by for usual maintenence. These reactors are a viable alternative to fossil fuel reactors. However, in order to meet the rising energy demand, we would have to build around 100 of these smaller reactors just to meet the expected rise in energy demand over the next decade. That means that if we want to become dependant upon nuclear energy for a bigger chunk of our energy needs, we need to start building NOW......

    With the recent advances of high lumen output LED's and LED arrays, I would think it would be advantagous to move in that direction for a flash instead of a Xenon strobe flash. Makes sense from a power standpoint.

    Note that according to the study, the vast leading majority of robots are ones used in industry most often for manufacturing (the study mentions the auto industry, but semiconductor fabs are starting to become all robotic as well). The study goes on to say that even though household robots will become more common, the overwhelming majority will still be industrial.

  15. Re:How to make a software project work...for real on Organizational Patterns of Agile Software Development · · Score: 1

    The simple fact is that small groups can accomplish more per given size then large groups because of a more focused involvement on the part of the program. When in large groups, the programmers (and people in general) tend to lose motivation because often they lose sight of how their portion is benefitting the end project. Also, it is easier to manage 3-10 people then it is to manage 100 people, because as the organization grows, it now requires a more complex management hiearchy. The downside: Small groups take longer to develop, and even though the product is generally alot better, they normally get trounced by brand named products.

    All of the existing regulations in place for High Power Rocketry would apply to these rockets. You need a cleared FAA wavier in order to fly anything above 2500 feet. These are not hard to obtain, and 95% of the population in the US is within 3-4 hours of a high power capable launch site. On the other hand, rockets are NOT capable of shooting down planes. Some government agencies tried proving this before, but were unsuccessful and looked like idiots doing it. Also, the rockets are not impressive at all. You can construct a much larger rocket out of composites with a homebuilt hybrid engine using HTTB and LOx as fuel compenents for under 500 dollars.

    I think they might be heading in a little too quickly. Then again, it makes sense with MRAM on the horizon. Fullerenes (i.e. nanotubes and bucky balls) have been around for a while now. It doesn't surprise me that they are used in memory considering their application in Organic solar cells and some OLED applications.

  19. Re:A question on 40" OLED Television Revealed at SID · · Score: 1

    It is a whole lot more complicated than that. But first, Sieko Epson is the only company using ink jetting technology to print their displays. All of the others use a variation on shadow masking used in silicon. Purity is by far the biggest issue and problem plaguing these devices, and is far worse than that of silcon. These polymers won't go into solution, most simply don't dissolve in even the nastiest of solvents. This results in all these polymer nanoparticles floating around in a solvent, and there will be other nanoparticles floating around with them. We try to filter the other nanoparticles out, but because the polymer itself is in suspension, we end up filtering the polymer out too. Production is then often done in class 10 cleanrooms. This purity issue also effects resolution and display lifetime. Also, in traditional LED devices, the silcion used is a crystalline structure. Compare this with a bowl of spaghetti for the polymers. It all sums up to that "ink jetting technology" is very misleading in it's name. Don't think of printing pixels on a substrate like printing a photo on a piece of paper. Think of jetting these polymer suspension onto a substrate so that they align within a nanometer of where they were supposed to be, on top of 7 other different layers printed (the alignment is like that in CPU chip manufacture). Now, with millions of pixels more to be printed on the 40" display, this results in so much more having to be aligned. If one in every 10 devices failed (a year ago, this was a very generous number), that's a 10th of the screen that is not working. It surprises me that they can achieve that kind of circuit density through ink jetting.

    Those apps are just the tip of the iceberg. Everything now becomes more minaturized, cause elctronics can be embedded in the plastic frame. Instead of pulling down a screen and using an overhead projector, the screen itself now emits the display. Computerized touch screens can be built into desks for schools, revolutionizing learning yet again. How about billboard ads that electronically displayed. Displays on storefronts to market sales and specials. This list is endless and is only limited by imagination. The best part is it means more programming jobs for all of us!

  21. Re:Lifetime of OLEDs? on 40" OLED Television Revealed at SID · · Score: 1

    Current liftetime is not very long due to problems with particle control and the organic nature of the polymers themselves. Right now, the average lifetime is around a month, however, the industry is barreling ahead trying to fix this problem. When OLED displays are sold to consumers, expect the liftime to be at least a decade or so.

  22. Reinventing the wheel all in the name of profit on 40" OLED Television Revealed at SID · · Score: 2, Informative

    The OLED industry should have been fully commercialized 4 years ago. However, for whatever reason, the industry didn't take a clue from the semiconductor folks and, as a result, has been reinventing the wheel the silcon industry invented 30 years ago. Time after time I hear the OLED manufacturers having problems with black spots on the screen (i.e. OLED device failure), resolution problems, and short display lifetime. I just shake my head because the silcon industry did the exact same thing 30 years ago. They have a purity problem, plain and simple. The silcon used in IC's today is 99.99% pure; any less and there are problems particle contaminates. In contrast, today's organic conducting polymers, including Light emitting homopolymers, copolymers, oligimers, and doped and undoped Fullerenes (buckyballs, and carbon nanotubes) have purities from 95% to 99.5% when ordered from companies like American Dye Source, which is one of the best. Until the OLED industry starts controlling their particles through better, more purified suspensions and moving production into class 10 clean rooms (which has been done, but only recently), they will continue to be plagued by these problems. Looks to Seiko Epson to lead the way for OLED displays. Many companies are using traditional silcon processes to manufacture their displays while integrating roll-to-roll processing. This process is traditionally accomplished through a series of shadow masks to lay the materials down in proper order (think really fine stencil). However, Sieko has adapted their current printing technology in order to use ink jetting coupled with roll to roll processing in what I think is a better production process overall. The OLED industry is going to revolutionize the world of displays. Because, the materials and processing are so cheap compared to silcon, companies are scrambling to develop the technology to produce displays for cellphones, PDA's, and other small devices in addition to tv's and computer displays. And, while they may be priced cheaper for the consumer, the companies will still make a tremendous profit from it.
