Unpacking Badges for Lifelong Learning [25Sep11] - 0 views

  • Is there some core definition or badge-ness to explain what makes badges unique?
  • If badges are like degrees, diplomas, grades, or currency -- which many of us have collected and displayed and benefited from -- what's wrong with them? Why are badges worse or better? If badges are visual signs of rank, reputation, membership, and identity, and are just another way to show affiliation, why are they different than, say, titles, clothing, hair, language, accents, bumper stickers, friends, or an alma mater?

  • Because badges hinge on motivation. Most of the energy in the badges conversation seems to have roots in the different ways people think about motivation, and more specifically about motivation and learning. What motivates learners to learn? What de-motivates them? 
  • Where's the line between motivating a learner and manipulating them?
  • For me, the most interesting intersection of the Badges for Lifelong Learning conversation is where learning theories overlap with research into virtual communities, new collectives, commons-based peer production -- whatever you want to call what we do online. A good deal of Internet research is about participation and motivation. If anything connects the badges community, it's seems to be the belief that more participation is better.
  • The communities of practice research links new collectives like Wikipedia with learning and identity, and authenticity is thought to affect people's motivation to learn and participate and reach goals.
  • There's this obscure ID Compensation theory that isn't even on Wikipedia! yet!
  • What if badges are just one more way to represent feedback? What if they're the best, most versatile way to provide feedback, whether that feedback is many-to-one, one-to-one, or many-to-many?

Study: Someday our bodies could 'talk' to gadgets - Tech News and Analysis [23Sep11] - 0 views

  • UW researchers say this new type of transistor could one day understand or even control body functions.
  • Materials scientists are looking at these proton-based microscopic transistors for future advances in prosthetics and biological sensing.
  • In the body, protons activate “on” and “off” switches and are key players in biological energy transfer. Ions open and close channels in the cell membrane to pump things in and out of the cell. Animals, including humans, use ions to flex their muscles and transmit brain signals. A machine that was compatible with a living system in this way could, in the short term, monitor such processes. Someday it could generate proton currents to control certain functions directly.

  • A first step toward this type of control is a transistor that can send pulses of proton current. The prototype device is a field-effect transistor, a basic type of transistor that includes a gate, a drain and a source terminal for the current. The UW prototype is the first such device to use protons.
  • Because their device’s proton current can be switched on and off, it can act as its own kind of electronic current, according to Marco Rolandi, a UW assistant professor of materials science and engineering. The transistor itself is “a twentieth the width of a human hair,” or about 5 microns wide. It is made of a compound, chitosan, found in both crab shells and squid pen (the structure inside a squid’s body that muscles attach to).
  • The first applications of this research will come some time “in the next decade or so,” and will be aimed at direct sensing of cells in a lab, researchers say
  • But further out they could be implanted directly in living organisms to monitor or control bodily processes.

  • Technology will also transform our daily urban existence in a myriad number of small ways, says Philip Sheldrake, director of Intellect, which represents the UK technology industry. He believes 2011 is the year the ultimate in connectivity – the "internet of things" - will finally take hold: "It is almost like we have got a perfect storm coming. There are a number of technological innovations and a number of calls on this technology coming together at the same time."
  • Urban areas are ultimately likely to be transformed by sensors that transmit data on conditions such as energy consumption, pollution, and temperature, which can be used to create a "smart grid" system. Such a grid could automatically turn on domestic devices such as washing machines at night when consumption is low and regulate heating, water supply and air conditioning systems. And as we negotiate our way around urban transport systems, sensors will also track our movements sending information back to bus companies or electric car hire schemes.

Service Blackouts Threaten Cloud Users - Technology Review - 0 views

  • Damage control: Internet discussion about the service outage that struck Amazon Web Services in April spiked as soon as problems began (April 21st) and again when Amazon explained the cause (April 29th). The data is based on selected mentions on Twitter, blogs, and in online media. Alterian
  • Just ask Jeff Malek, cofounder of BigDoor, a Seattle company whose game software is hosted on the public servers of Amazon. Last April, problems in a Northern Virginia data center crippled Amazon's northeast operations, affecting many cloud-based businesses. Spotty service over four days left BigDoor scrambling to find technical solutions and issuing a steady stream of apologies to its 250 clients. Since then, BigDoor has joined a growing number of companies that are seeking new ways of building outage-resistant systems in the cloud, often at additional expense and inconvenience.
  • Even though outages put businesses at immense risk, public cloud providers still don't offer ironclad guarantees. In its so-called "service-level agreement," Amazon says that if its services are unavailable for more than 0.05 percent of a year (around four hours) it will give the clients a credit "equal to 10% of their bill." Some in the industry believe public clouds like Amazon should aim for 99.999 percent availability, or downtime of only around five minutes a year.

  • Indeed, Stump says only one thing is 100 percent certain when it comes to the cloud: "You always have to architect your systems under an assumption of failure."

  • Smart Grid deployments are not only delivering improved energy security, grid reliability, and consumer control to us, they are bringing the Internet of Things closer to reality.  The Internet of Things (IoT) is defined in the Smart Grid Dictionary as a conceptual description of the ability to connect any objects with an IP address and some level of embedded intelligence to the communications network.  Embedded intelligence can include localization, sensing, identification, security, networking, processing, and control.

  • 2008 Elections From the Jan. 3 Iowa caucuses to the Nov. 4 general election, information graphics were a major component of the New York Times election coverage. Interactive maps on the nytimes.com home page and inside the web site were rich with information, but easy to navigate.
  • 2008 Olympics Coverage In August 2008, The New York Times graphics department published more than 30 interactive graphics covering subjects ranging from the Olympic torch to the medal count. The package included graphics produced in advance of the games, plus more than a dozen produced on deadline analyzing results from a vareity of events. Because NBC tape-delayed the showing of many events, these graphics frequently were readers' first visual picture of how a race was won.
  • Flight 1549 Lands in the Hudson River When U.S. Airways Flight 1549 made an emergency landing in the Hudson River, graphics editors immediately began reporting what happened in the air, building 3-D models of the plane and developing an interactive graphic. The graphic was initially published the same day as the emergency landing, and updated over the next several days as more information was released. Published Jan. 15, 2009
