The Most Wonderfully Ridiculous Movie Computers of All Time - 0 views

  •  
    I had to post one more just for fun. The computers from Desk Set from Willy Wonka and the Chocolate Factory thankfully made the list. And only one computer from a Kubrick movie made the list. I'll let you guess which one.

Why Your IT Spending Is About to Hit the Wall - Wall Street & Technology - 0 views

  • Between 2006 and 2010, demand for processing cycles (MIPS, servers and the like) has slowly approached an 18 erpcent annual growth rate in the big banks. Storage, by the way, has hit 45 percent per year -- the advent of Big Data is here -- and although the unit cost of storage is still dropping, storage cost pools around the financial industry are expanding out of control. The growth phenomenon is now exacerbated by market conditions, and Moore's Law just isn't enough.
  • Taking a step back, you will likely ask, "How can this be true?" The answer involves yet another "law" -- actually, a paradox observed in the late 1800s -- "Jevons paradox," which states:Technological progress that increases the efficiency with which a resource is used tends to increase (rather than decrease) the rate of consumption of that resource. William Stanley Jevons developed this hypothesis in 1865, based on his observations of coal consumption vis-à-vis the technology advances designed to improve the efficiency of coal usage. It was his argument that these improvements alone could not be relied on to reduce consumption; rather, they would lead to increased consumption -- and he was right. Today we talk about elastic computing; in 1865 Jevons focused on "elastic coal" – well, at least the demand was elastic.
  • So the aforementioned growth in demand (passing the 20 percent mark per year) is actually fueled in part by the inherent efficiencies created by Moore's Law. Through 2010 we were in the Moore's Law zone of managing IT costs downward. Now we are a new world governed by the effects noted by Jevons.

    Because of Moore's Law - the decreasing costs of computing power, we've become a world of Big Data and are now consuming ever more computing power at a rate that exceeds Moore's Law.

Smartphones Have Bridged The Digital Divide - ReadWrite - 0 views

  •  
    "Since at least the 1990s, when personal computers first became commonplace, public policy experts have worried the ill effects of a Digital Divide. That is, a learning, socialization and economic gap across socio-economic status, race and gender caused by unequal access to computing resources."

Religious Websites Are Worse for Your Computer than Porn Sites - 1 views

  • Religious sites had and average of 115 software threats, while porn sites only had 25. The religious sites were mostly full of fake anti-virus software, which sounds relatively harmless, but it can leave an unsuspecting user's computer totally vulnerable. Symantec wasn't able to come up with a good explanation for why the religious were such a popular target for the fake software.

Researcher runs IP network over xylophones - 2 views

  • With OSI, each layer is encapsulated from the others, allowing new technologies to replace older ones without disrupting the system as a whole. In this exercise, humans operated layer 1, the physical layer, where the bits are physically moved from one system to another. To the two computers communicating, however, it made no difference that people were conveying the bits back and forth with their xylophones. "With a properly configured network interface and operating system, an application does not know -- and does not need to know -- the logistics of what is known as the physical layer,"
  • Typically, it takes about 15 minutes to transmit a single packet at this rate -- if the volunteer is patient enough to complete a whole packet, and doesn't hit any wrong notes in the process. Such dedication and proficiency has turned out to be a rarity in trials, however. "Humans are really terrible interfaces,"
  • As an LED lights up, the human participant strikes the corresponding key on the xylophone. Piezo sensors are attached to each xylophone, so that they are able to sense when a note is played on the other xylophone. The Arduino for the receiving computer senses the note and then converts it back into hexadecimal code. And when the second computer sends a return packet, the order of operations is reversed.

FBI agents raided Detroit Public Library over allegations of contract fraud - 0 views

  •  
    The FBI raided the Detroit Public Library over allegations a library official had ties to a contractor hired to update the library's computer systems and personally benefited from the contracts--which were in the $2 million dollar range. Interestingly the president of the Detroit Library Commission says the the issues were longstanding the raid was overdue in happening.

More Relevant Than Ever - 0 views

  •  
    The second of four New York Times articles, written by a librarian and therefore supportive, but he made several good points. Most learning centers offer computer skills in only English, but to offer those in four foreign languages is impressive, along with the move to circulating digital media and devices.

CheckThese Out at the Library: Blacksmithing, Bowling, Butchering - 0 views

  •  
    An interesting article about some of the diverse offerings the Overland Park county library has begun to offer, including classes and seminars on Wii bowling and hog butchering, which has helped raise attendance 29% from 2004-2010. One comment does ring true, from Michael Gorman, former president of the ALA: "I hope the library doesn't turn into something that is a type of cooking-class meeting place with computers attached and no books."

PaperTabs - 0 views

  •  
    An interesting technical development of a flexible "PaperTab" that allows both handling of documents like paper but also allows each "tab" (equivalent to a sheet) to to be used like a touchscreen and to share data by tapping them together. Intriguing, but I noticed a computer cable connected to each Tab which means several would require a mess of wiring, and the display contrast wasn't impressive.

Librarian foot soldiers enlisted to help with Obamacare enrollment - Washington Times - 0 views

  •  
    "The nation's librarians will be recruited to help people get signed up for insurance under President Barack Obama's health care overhaul. Up to 17,000 U.S. libraries will be part of the effort to get information and crucial computer time to the millions of uninsured Americans who need to get coverage under the law."

Computers powered by swarms of crabs - 0 views

  • The crab swarms were placed at the entrances of the logic gates and encouraged to move by a looming shadow that fooled them into thinking a predatory bird was overhead. The results closely matched the simulation, suggesting that crab-powered computers could indeed be possible.

Oracle thinks you can copyright a programming language, Google disagrees | The Verge - 0 views

    • anonymous
       
      Comments here are awesome too.
  •  
    Oracle is suing Google over the use of their Java API's in Android. This should be an interesting case. Google argues that while you can copyright a finished product, you shouldn't be able to copyright the computer language used to build the product - just like a novelist can copyright a book but nobody can copyright English. Oracle disagrees and says that if the language is unique enough, then it should be protected. They cite Klingon as an example. I read through Oracle's filing and it actually looks pretty strong. I didn't bother reading Google's because it's pretty clear that Google is missing the point that Oracle isn't upset that they used Java, but that they bundled all the extra API's. I really feel for the judge and jury having to hear this case. Oracle's brief isn't exactly light on the technical details...

New 'Digital Divide' Seen in Wasting Time Online - NYTimes.com - 2 views

  •  
    Librarians may find this paragraph interesting: The new divide is such a cause of concern for the Federal Communications Commission that it is considering a proposal to spend $200 million to create a digital literacy corps. This group of hundreds, even thousands, of trainers would fan out to schools and libraries to teach productive uses of computers for parents, students and job seekers.

Louisana eliminates state funding for libraries - 0 views

  •  
    The state budget for the upcoming year eliminates all funding for public libraries. Commissioner of administration Paul Rainwater stated the libraries could be supported by local, not state dollars. There are two Federal grants within the budget, but they do not cover things such as desktop computer support. Rural libraries with the least amount of property tax are going to be among those most hard hit.

American Youth Read Books in Print (For Now) - 0 views

  •  
    An interesting survey where it shows younger readers 16-29 are more likely to use books, use traditional library services, and read e-books on an computer rather than an e-book reader than their older (30-49) counterparts.

Will These Guys Kill The Computer Interface As We Know It? - 0 views

  •  
    Wile not particularly new, the gesture technology here uses ideas inspired by devices such as the Kinect motion capture for the Xbox. While interesting I agree with some of the comments that performing gestures for hours on end would be physically fatiguing, along with the impreciseness that a gesture will always be read by the machine correctly. What I would be more interested in seeing is interface design that would offer an improvement over how today's materials are organized on a computer's file system or desktop.

Evolution of the myCloud Program: From Idea to Practice - 0 views

  •  
    This was a concept that I wasn't too sure if it wasn't ready for prime time or was simply a bad idea. Library patrons could sign up for a "Cloud" account and be given a thin client laptop that would access a Windows 7 image via Citrix which is "their" computer to install programs on or use as needed. However the initial outlay was $300,000 with $5,000 a year ongoing maintenance costs and considerable bandwidth requirements to stream an HD Windows desktop. Further it was limited to only laptops used in the library with a maximum base of 160 users. I honestly couldn't see this as a good idea because of the cost and limited use. It would be cheaper to rent out laptops and re-image when they are returned.
