    A valiant effort to make the best use of a 'bare bones' classroom.

    Interesting article and video about a new way of teaching children to program. A credit-card sized computer designed to help teach children to code has gone on sale for the first time. The Raspberry Pi is a bare-bones, low-cost computer created by volunteers mostly drawn from academia and the UK tech industry.

    I just heard about this from a friend and then stumbled across your link - and then wound up on the Raspberry Pi website to try to find out more about the education component of it (which is supposedly the whole motivation). Right now, the website is focused on showcasing the capabilities of the device and the hardware/software choices that they made. I was disappointed to find, when looking through their FAQ, that there is only one small blurb about educational material in which they vaguely state that support resources are currently under development. No doubt they are allowing a greater number of people access to a cheap Linux machine, but that does not mean those people are going to use it to learn to program. I'll be interested to see if the focus really does shift to education as the resources come together... right now it just seems like a cool new toy for a Linux geek (with the potential to be so much more!)

  • George Whitesides has developed a prototype for paper "chip" technology that could be used in the developing world to cheaply diagnose deadly diseases such as HIV, malaria, tuberculosis, hepatitis and gastroenteritis.
  • Patients put a drop of blood on one side of the slip of paper, and on the other appears a colorful pattern in the shape of a tree, which tells medical professionals whether the person is infected with certain diseases.
  • hey test for multiple diseases at once. They also show how severely a person is infected rather than producing only a positive-negative reading
  • ...2 more annotations...
  • solutions to complicated problems often are found in simple, low-cost technologies.
  • he paper may mold in humid, hot climates. And it's still important for people to get access to doctors so they know what to do about their diagnoses,
