How Small Can Computers Get? Computing in a Molecule 143

ScienceDaily on what the future might bring for atomic-scale computing: "Joachim, the head of the CEMES Nanoscience and Picotechnology Group (GNS), is currently coordinating a team of researchers from 15 academic and industrial research institutes in Europe whose groundbreaking work on developing a molecular replacement for transistors has brought the vision of atomic-scale computing a step closer to reality. Their efforts, a continuation of work that began in the 1990s, are today being funded by the European Union in the Pico-Inside project. ... The team has managed to design a simple logic gate with 30 atoms that perform the same task as 14 transistors, while also exploring the architecture, technology, and chemistry needed to achieve computing inside a single molecule and to interconnect molecules."

FBI Issues Code Cracking Challenge 222

coondoggie writes to tell us that the FBI has issued another cracking challenge for a new cipher on their site. Tens of thousands responded to a similar challenge last year. In addition to the challenge, the FBI is also offering a few primers on the subject. There are a number of sites offering cipher challenges, but it's funny to see the FBI encouraging such behavior.

Comment Re:Why do they have to do this much coding? (Score 2) 119

I'd suggest looking at pricing for radiation-hardened parts sometime. A radiation-hardened 2 Megabyte SRAM on a programs I am working on costs around $40,000, and it's not even particularly quick. There are very real code size considerations for space programs, especially when all of this has to run on a battery!

EFF Case Against AT&T To Go Forward 227

Tyler Too writes "The NSA wiretap lawsuit filed by the EFF will apparently be moving forward. A federal judge has denied the government's request that the EFF's lawsuit against AT&T be dismissed. Among other things, the judge ruled that 'if the government has been truthful in its disclosures, divulging information on AT&T's role in the scandal should not cause any harm to national security.' The case will now move forward, pending a government appeal."
