HP Dreams of Internet Powered by Phone Chips (And Cow Chips) | Wired.com - 0 views

  • For Hewlett Packard Fellow Chandrakat Patel, there’s a “symbiotic relationship between IT and manure.”
  • Patel is an original thinker. He’s part of a group at HP Labs that has made energy an obsession. Four months ago, Patel buttonholed former Federal Reserve Chairman Alan Greenspan at the Aspen Ideas Festival to sell him on the idea that the joule should be the world’s global currency.
  • Data centers produce a lot of heat, but to energy connoisseurs it’s not really high quality heat. It can’t boil water or power a turbine. But one thing it can do is warm up poop. And that’s how you produce methane gas. And that’s what powers Patel’s data center. See? A symbiotic relationship.

  • Financial house Cantor Fitzgerald is interested in Project Moonshot because it thinks HP’s servers may have just what it takes to help the company’s traders understand long-term market trends. Director of High-Frequency Trading Niall Dalton says that while the company’s flagship trading platform still needs the quick number-crunching power that comes with the powerhog chips, these low-power Project Moonshot systems could be great for analyzing lots and lots of data — taking market data from the past three years, for example, and running a simulation.

Silicon Valley celebrates Moore's Law 50 years anniversary - 2 views

  •  
    A bit late, but it is very interesting and instructive to listen to Gordon Moore's words "It almost doubled every year (...) so I said in the next 10 years it's going to continue to double every year, we are going to go from 16 components on a chip to 16 000. Pretty wild extrapolation!". This extrapolation (exponential with only 5 initial points) is now well-known and is one of the things that changed the World, it is pretty amazing how this "wild" futuristic vision came true.

    A great source is also the blog from Chris Mack (http://life.lithoguru.com/?p=451) who is a semicon pioneer and publisher of many books on the subject. He wrote an article for IEEE Spectrum on Moore's law and its future. Find it here, http://spectrum.ieee.org/semiconductors/processors/the-multiple-lives-of-moores-law

    Whenever I think about moore's law and extrapolating like that I end up back at this xkcd comic https://xkcd.com/605/

The chips are down for Moore's law : Nature News & Comment - 4 views

  •  
    Super lol for all those who abused of the law in their slides / opinions / decisions ..
  •  
    I used the law in some slides :-)! This sentence is more or less the summary "The end of Moore's law is not a technical issue, it is an economic issue,". As Moore's himself recognized last year, the Moore's law itself is a pretty wild extrapolation of one exponential growth when there were only 5 experimental points. It is remarkable however how the semiconductor industry grabbed this and made every single effort to make it true. This effort was rewarded by turning semiconductor industry into one of the most important industries worldwide. Now these are challenging times indeed, and "when tide is gone, we realize who was swimming naked"...

    The "law" is one of the most successful concrete predictions of the technological future... Still very impressive and a lot more long-lived than Moore had probably ever dreamed of :)

Smallest transistor with 1-nanometer carbon nanotube gate - 0 views

  •  
    Amazing engineering feat: 1 nm transistor. Besides we can argue Moore law is still OK, dennard scaling is gone and with it the performance boost, as alluded subtly. Link article: http://science.sciencemag.org/content/354/6308/99.full

The Straight Dope: Why don't we ever see pictures of the floating island of garbage? - 0 views

  •  
    To follow up our discussio at breakfast
  •  
    For all your statistics needs. The "Plastic Debris in the World's Oceans Report - UNEP" www.unep.org/regionalseas/marinelitter/.../docs/plastic_ocean_report.pdf‎ "Densities of plastic debris (Moore et al. 2001). Using nets to collect debris, the abundance of floating plastic averaged 334,271 pieces/km2" More worrying maybe is (http://www.ncbi.nlm.nih.gov/pubmed/22610295) "Our oceans eventually serve as a sink for these small plastic particles ("UV degraded surface plastic") and in one estimate, it is thought that 200,000 microplastics per km(2) of the ocean's surface commonly exist."

Repeated self-healing in composite materials - 1 views

  •  
    Sottos, White, Moore, and their team created 3D vascular networks-patterns of microchannels filled with healing chemistries-that thread through a fiber-reinforced composite. When damage occurs, the networks within the material break apart and allow the healing chemistries to mix and polymerize, autonomously healing the material, over multiple cycles.

NASA Considering Gas Stations in Space - FoxNews.com - 3 views

  •  
    Chris Moore is a good guy and one very open minded to new ideas and concepts at NASA; the fact that this was picked up by fox news must be that they could relay this to "gas stations" :-)
