Introducing the $25 Computer
The British nonprofit group Raspberry Pi aims to inspire young programmers with a desktop computer so inexpensive that schools could hand them out to students free of charge.
What's the Latest Development?
A new computer designed by the British nonprofit group Raspberry Pi currently looks like nothing more than a chip on a stick, but by next year, the company says the prototype could be made into a $25 computer. David Braben, a member of Raspberry Pi, says he wants to inspire a new generation of computer engineers by making programming more accessible than ever. While computer literacy classes teach students how to use a spreadsheet, classes that teach programming and more creative computer use have declined, says Braben.
What's the Big Idea?
The new computer device has a powerful processor similar to those in high-end smart phones, a memory card reader for 32 gigabytes of storage, a screen connector ready for HD graphics, and up to three USB ports for a keyboard and other accessories. "Raspberry Pi's open-source software can handle everything that kids now come to expect—Web browser, e-mail, Facebook access—while providing tools to program and share their own creations. If a student deletes essential files by mistake or creates inappropriate material, a simple command will wipe the drive and return the machine to its original state."
New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
