How a Key Enzyme Repairs Sun-Damaged DNA 97

BraveHeart writes "Researchers have long known that mammals, including humans, lack a key enzyme — one possessed by most of the animal kingdom and even plants — that reverses severe sun damage. For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA. 'Normal sunscreen lotions convert UV light to heat, or reflect it away from our skin. A sunscreen containing photolyase could potentially heal some of the damage from UV rays that get through.'"

Open Sarcasm Fighting Copyrighted Punctuation 155

pinkushun writes "SarcMark is a copyrighted punctuation mark, that claims 'It's time that sarcasm is treated equally!' Pretty damn cheeky while they're charging for their software, which only inserts their punctuation through a hotkey. Open Sarcasm is destroying SarcMark by advocating a new punctuation mark (not displaying here properly — alt+U0161) as the new open and free sarcasm symbol. Either way, this will be one interesting turnout. With bad unicode support across the web, displaying the characters properly might be an issue. PS Left out sarcastic end sentence as Slashdot doesn't display the U0161 character."

New LLVM Debugger Subproject Already Faster Than GDB 174

kthreadd writes "The LLVM project is now working on a debugger called LLDB that's already faster than GDB and could be a possible alternative in the future for C, C++, and Objective-C developers. With the ongoing success of Clang and other LLVM subprojects, are the days of GNU as the mainstream free and open development toolchain passé?" LLVM stands for Low Level Virtual Machine; Wikipedia as usual has a good explanation of the parent project.

Happy Towel Day 122

An anonymous reader writes "While Douglas Adams continues his attempt to set a new record for the longest extended lunch break, geeks all over the universe pay tribute to the beloved author by celebrating the tenth edition of Towel Day. Towel Day is more alive than ever. This year Richard Dawkins, one of Adams' best friends, has tweeted a Towel Day reminder to his numerous followers. The CERN Bulletin has published an article on Towel Day. There has been TV coverage and there will be a radio interview. The Military Republic of the Deltan Imperium, a newly formed micronation, has recognized Towel Day as an official holiday. In Hungary several hundreds of hitchhiker fans want to have a picnic together in a park. And there's a concert, a free downloadable nerdrap album, a free game being released, the list goes on and on."

New Linux Petabyte-Scale Distributed File System 132

An anonymous reader writes "A recent addition to Linux's impressive selection of file systems is Ceph, a distributed file system that incorporates replication and fault tolerance while maintaining POSIX compatibility. Explore the architecture of Ceph and learn how it provides fault tolerance and simplifies the management of massive amounts of data."

EA Editor Criticizes Command & Conquer 4 DRM 266

Command & Conquer 4's DRM hasn't garnered Electronic Arts as much bad press and fan outrage as Ubisoft's scheme, despite being very similar. Nevertheless, it's been causing problems and frustrations for some users, including EA.com's own editor-in-chief, Jeff Green. An anonymous reader points this out: "Green wrote on his Twitter account late last week: 'Booted twice — and progress lost — on my single-player C&C4 game because my DSL connection blinked. DRM fail. We need new solutions.' He continued later, 'Well. I've tried to be open-minded. But my 'net connection is finicky — and the constant disruption of my C&C4 SP game makes this unplayable. The story is fun, the gameplay is interesting and different at least — but if you suffer from shaky/unreliable DSL — you've been warned.'"

Planned Nuclear Reactors Will Destroy Atomic Waste 344

separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

Submission + - Linux Distro for an Old Lappy (wikipedia.org) 2

BJ_Covert_Action writes: So I just zero filled an old Dell Inspiron 4100 laptop and am looking to revive it into a decent machine. It is running a Pentium-III M processor, 128 MB of RAM, and has a 30 GB hard drive slotted into it. I would like to slap a Linux distribution on the old girl as I figure that is the best way to make use of its hardware. Currently, I only have experience with Ubuntu on a couple of desktop computers. I have been fiddling with Ubuntu for about a year and a half now. I am comfortable on the command line, with the Gnome desktop, and with the file structure (i.e. /etc, /usr, and so on). I don't really know how to rank myself as a user other than that I tend to be able to get things done and, as long as I can get to Google, I am pretty decent at learning new Linux tricks on Ubuntu.

However, for this old clunker of a laptop, Ubuntu is a bit heavy. So I am looking for a newer (possibly better) and smaller distribution. I would like to use the laptop, primarily, for internet access, office applications, some music (in mp3 format), and, of course, perl hacking. That said, responsiveness is more important to me than having access to scores of programs. I would also like to get some new lessons out of this distribution and maybe learn a bit more about Linux (I hear both Arch Linux and Slackware are good for that). Some ease of use would be nice as jumping feet first into a full inferno of bewilderment would likely frustrate me. Furthermore, I might use this little laptop as a platform to let some friends try out Linux and see what they think.

So, with all that said, I have looked at Puppy Linux, Damn Small Linux, Xubuntu, Debian, PCLinuxOS, Slackware, Arch Linux, and Linux Mint. I am leaning towards Puppy Linux or DSL as the rest seem to be a little hardware hungry for my particular system. Puppy Linux appears to focus on user friendliness, but I don't know how much I could learn from it. DSL seems like it could be one hell of a ride, but from what I have read, there is no package management system (though I guess there is some kind of apt enable option you can check now?) which seems like it could make using DSL a pain. When it comes down to it. I am looking to clear up some of these rumors I have heard and get a few dotters' thoughts and ideas on which distributions might meet my requirements best.

Also, as one last note, I tend to use the internet to figure out solutions to most of my problems, so any distributions with a vibrant online community earn a ++ in my book.

Apple Removes Wi-Fi Finders From App Store 461

jasonbrown writes "Apple on Thursday began removing another category of apps from its iPhone App Store. This time, it's not porn, it's Wi-Fi. Apple removed several Wi-Fi apps commonly referred to as stumblers, or apps that seek out available Wi-Fi networks near your location. According to a story on Cult of Mac, apps removed by Apple include WiFi-Where, WiFiFoFum, and yFy Network Finder."

Typical Windows User Patches Every 5 Days 388

CWmike writes "The typical home user running Windows faces the 'unreasonable' task of patching software an average of every five days, security research company Secunia said on Thursday. 'It's completely unreasonable to expect users to master so many different patch mechanisms and spend so much time patching,' said Thomas Kristensen, the company's CSO. The result: Few consumers devote the time and attention necessary to stay atop the patching job, which leaves them open to attack. Secunia says that of the users who ran the company's Personal Software Inspector in the last week of January, half had 66 or more programs from 22 or more different vendors on their machines. ... Secunia has published a white paper (PDF) that details its findings."

Long-Term Storage of Moderately Large Datasets? 411

hawkeyeMI writes "I have a small scientific services company, and we end up generating fairly large datasets (2-3 TB) for each customer. We don't have to ship all of that, but we do need to keep some compressed archives. The best I can come up with right now is to buy some large hard drives, use software RAID in linux to make a RAID5 set out of them, and store them in a safe deposit box. I feel like there must be a better way for a small business, but despite some research into Blu-ray, I've not been able to find a good, cost-effective alternative. A tape library would be impractical at the present time. What do you recommend?"

After 2 Years of Development, LTSP 5.2 Is Out 79

The Linux Terminal Server Project has for years been simplifying the task of time-sharing a Linux system by means of X terminals (including repurposed low-end PCs). Now, stgraber writes "After almost two years or work and 994 commits later made by only 14 contributors, the LTSP team is proud to announce that the Linux Terminal Server Project released LTSP 5.2 on Wednesday the 17th of February. As the LTSP team wanted this release to be some kind of a reference point in LTSP's history, LDM (LTSP Display Manager) 2.1 and LTSPfs 0.6 were released on the same day. Packages for LTSP 5.2, LDM 2.1 and LTSPfs 0.6 are already in Ubuntu Lucid and a backport for Karmic is available. For other distributions, packages should be available very soon. And the upstream code is, as always, available on Launchpad."

Sony Develops a Universal Game Console Controller 62

Go Rumors has discovered that Sony recently applied for a patent on a "universal game console controller." According to the patent filing, the controller "includes a hand-holdable housing and a touch sensitive liquid crystal display (LCD) on the housing. The LCD is caused to present, depending on what type of game console a user has selected, a controller key layout for a first type of game console or a controller key layout for a second type of game console. A key layout includes plural keys selectable by a user to input commands to a game console."
