+ - Remote controlling insects' flight->

An anonymous reader writes: Forget the Internet of Things! The next hype is the Internet of Insects! Researchers have equipped bugs with a microchip and a radio transceiver which allow them to remotely stimulate parts of the bug's brain and influence flight behavior:

"We demonstrated the remote control of insects in free flight via an implantable radio-equipped miniature neural stimulating system. [...] Flight initiation, cessation and elevation control were accomplished through neural stimulus of the brain which elicited, suppressed or modulated wing oscillation. Turns were triggered through the direct muscular stimulus of either of the basalar muscles. We characterized the response times, success rates, and free-flight trajectories elicited by our neural control systems in remotely-controlled beetles. We believe this type of technology will open the door to in-flight perturbation and recording of insect flight responses." (Link)

Here's some accompanying YouTube footage. On the technical side, this seems rather straight forward (off-the-shelf components like a TI MSP430 MCU and a CC2431 transceiver are used). However, I don't know whether I should find the whole thing disgusting or cool.

TwIP - An IP Stack In a Tweet 81 81

Adam Dunkels writes "Inspired by the Twitter-sized program that crashes Mac OS X, I just wrote a really, really rudimentary IP stack called twIP, small enough to fit in a Twitter tweet. Although twIP is very far away from a real IP stack, it can do the first task of any IP stack: respond to pings. The entire source code can be found in this 128-character-long tweet. For those who are interested in low-level network programming, a code walkthrough with instructions on how to run the code under FreeBSD is available here. The FAQ: Q: why? A: for fun."
