QR Codes As Anti-Forgery On Currency Could Infect Banks 289

New submitter planetzuda writes "Invisible nano QR codes have been proposed as a way to stop forgery of U.S. currency by students of the South Dakota School of Mines and Technology. Unfortunately QR codes are easy to forge and can send you to a site that infects your system. Banks would most likely need to scan currency that have QR codes to ensure the authenticity of the bill. If the QR code was forged it could infect the bank with a virus."
It's funny.  Laugh.

Researcher Runs IP Network Over Xylophones 83

joabj writes "Following up on experiments of running Internet Protocol(IP)-based networks with carrier pigeons or bongos, UofC grad student R. Stuart Geiger has demonstrated that it is possible to transmit simple ping requests across two computers using people playing xylophones. Throughput is roughly 1 baud, when the participants don't make any mistakes, or get bored and wander off. The OSI encapsulated model of networking makes this project doable, allowing humans to be inserted at Layer 1, the physical layer. Vint Cerf wasn't kidding when he used to say, 'IP on Everything.'"

Icons That Don't Make Sense Anymore 713

theodp writes "The Floppy Disk Icon, observes Scott Hanselman, means 'save' for a whole generation of people who have never seen one. That, and other old people icons that don't make sense anymore — Radio Buttons, Clipboards, Bookmarks, Address Books and Calendars, Voicemail, Manila Folder, Handset Phone, Magnifying Glass and Binoculars, Envelopes, Wrenches and Gears, Microphones, Photography, Televisions, Carbon Copies and Blueprints — are the subject of Hanselman's post on icons that are near or past retirement age, whose continued use is likely to make them iconic glyphs whose origins are shrouded in mystery to many."

Unblocking The Pirate Bay the Hard Way Is Fun 151

TheGift73 writes in with a link for those of you who like to do things the hard way. "Now that The Pirate Bay is being blocked by ISPs in the UK, millions of people have a new interest in accessing the site, even if they didn't before. The reasons for this are simple. Not only do people hate being told what they can and can't do, people – especially geeks – love solving problems and puzzles. Unlocking The Pirate Bay with a straightforward proxy is just too boring, so just for fun let's go the hard way round."

The Awesome Button 80

An anonymous reader writes "An awesome hardware hack which demonstrates how easily USB-based human interface devices (eg, Keyboards and Mice) can be created using the Arduino software environment." A very nice little project based on the Teensy USB Development Board. Reminds me of the breadboard electronics projects my Dad used to work on with me many years ago. "Great fun for young and old," you might say.
