Submission + - Plastic Memory Device Based On Electron Spins (

von_rick writes: From the article: "Our main achievement is that we applied this [vanadium tetracyanoethanide] polymer-based magnet semiconductor as a spin polarizer — meaning we could save data (spin up and down) on it using a tiny magnetic field — and a spin detector — meaning we could read the data back," Jung-Woo Yoo said.

A memory unit that is lighter and draws lower power levels would be a good replacement for conventional semiconductors. However, since the spins are controlled by application of magnetic fields, this technology would be susceptible to strong magnetic fields just like the magnetic tape memories. The article also mentions that the heat generated is significantly low, so it could be made to operate at higher frequencies, if technology permits, without the risk of overheating.

Submission + - CIA Software Developer Goes Open Source (

von_rick writes: Some of the people who manage and use the softwares used in CIA and defense related systems find it hard to work on cases when they have to pay, repay and keep paying for a program because it never becomes the property of the government even after paying hefty sums of money. Some of them seem to be in favor of open sourcing their work in order to share ideas and lower the costs involved in solving crime and managing the gathered intelligence.
