Printable Batteries Should Arrive Next Year 92

FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

Scientists Solve Century-Old Optics Mystery 265

evan_arrrr! writes "From the article: Since the early 20th century physicists have known that light carries momentum, but the way this momentum changes as light passes through different media is much less clear. Two rival theories of the time predicted precisely the opposite effect for light incident on a dielectric: one suggesting it pushes the surface in the direction light is traveling; the other suggesting it drags the surface backwards towards the source of light. After 100 years of conflicting experimental results, a team of experimentalists from China believe they have finally found a resolution."

On the State of Linux File Systems 319

kev009 writes to recommend his editorial overview of the past, present and future of Linux file systems: ext2, ext3, ReiserFS, XFS, JFS, Reiser4, ext4, Btrfs, and Tux3. "In hindsight it seems somewhat tragic that JFS or even XFS didn't gain the traction that ext3 did to pull us through the 'classic' era, but ext3 has proven very reliable and has received consistent care and feeding to keep it performing decently. ... With ext4 coming out in kernel 2.6.28, we should have a nice holdover until Btrfs or Tux3 begin to stabilize. The Btrfs developers have been working on a development sprint and it is likely that the code will be merged into Linus's kernel within the next cycle or two."

Paper Ballots Will Return In MD and VA 420

cheezitmike writes "According to a story in the Washington Post, 'Maryland and Virginia are going old school after Tuesday's election. Maryland will scrap its $65 million electronic system and go back to paper ballots in time for the 2010 midterm elections. In Virginia, localities are moving to paper after the General Assembly voted last year to phase out electronic voting machines as they wear out. "The battle for the hearts and minds of voters on whether electronic systems are good or bad has been lost," Brace said. The academics and computer scientists who said they were unreliable "have won that battle."'"

Don't Overlook Efficient C/C++ Cmd Line Processing 219

An anonymous reader writes "Command-line processing is historically one of the most ignored areas in software development. Just about any relatively complicated software has dozens of available command-line options. The GNU tool gperf is a "perfect" hash function that, for a given set of user-provided strings, generates C/C++ code for a hash table, a hash function, and a lookup function. This article provides a reference for a good discussion on how to use gperf for effective command-line processing in your C/C++ code."

First Impressions of Freespire 1.0 201

Nate writes "Freespire 1.0 was released a few days ago, taking the desktop-oriented Linspire distribution and making it freely available (as in beer) to the world. Linux Format has some first impressions of the release, focusing on its much-trumpeted media playback facilities thanks to codec licensing. Flash, Java, DVD and WMV support out-the-box — could this climb to the top of the desktop distro ladder?"

Rosen Believes RIAA is Wrong about P2P Lawsuits 287

Newer Guy writes "Former RIAA head Hilary Rosen now believes that the RIAA is wrong by pursuing their lawsuits of individuals for using P2P programs. In a blog post, she writes that she believes the lawsuits have 'outlived their usefulness' and states that the content providers really need to come up with their own download systems. She also is down on DRM, calling Apple's DRM 'a pain.'"

Comment UFO - Enemy Unknown / X-COM (Score 1) 1094

During a summer quite many years ago, I played UFO (aka X-COM) with some friends and we played it a little too much. It is a turn-based game were you have a certain "moves" for each soldier, then take turns and let the computer move, and so on.

One day, I wanted to go to the toilet, but I stopped halfways thinking "Not enough moves left this round". Damn - I really needed to go! :)
