New GPU Testing Methodology Puts Multi-GPU Solutions In Question

Vigile writes “A big shift in the way graphics cards and gaming performance are tested has been occurring over the last few months, with many review sites now using frame times rather than just average frame rates to compare products. Another unique testing methodology called Frame Rating has been started by PC Perspective that uses video capture equipment capable of recording uncompressed high resolution output direct from the graphics card, a colored bar overlay system and post-processing on that recorded video to evaluate performance as it is seen by the end user. The benefit is that there is literally no software interference between the data points and what the user sees, making it is as close to an ‘experience metric’ as any developed. Interestingly, multi-GPU solutions like SLI and CrossFire have very different results when viewed in this light, with AMD’s offering clearly presenting a poorer, and more stuttery, animation.” Read more of this story at Slashdot.

Millionaire Plans Mission To Mars In 2018

littlesparkvt writes in with news about the possibility of a privately funded Mars mission. “Millionaire Dennis Tito became the first paying customer to make a trip to the International Space Station and now he wants to launch a privately funded mission to Mars in 2018. Dennis paid a reported 20 Million to ride aboard a Russian rocket to the International Space Station and has since stayed out of the spotlight, until now. There’s no word whether the trip will include humans, there will be more information on that fact next week. Considering there is little time to train a crew for the mission the flight in 2018 will most likely be an unmanned probe. There’s also a possibility that the first mission to Mars from this private investor will harbor supplies for future astronauts. Plants and food are a possibility as they would take much less space than a full human crew.” Read more of this story at Slashdot.

The Strange, Secret Evolution of Babylon 5

February 22, 2013, marks the 20th anniversary of the premiere of Babylon 5: The Gathering , the pilot film for what would eventually become the Babylon 5 television series. The show arguably changed the way narrative television works, and Babylon 5 creator J. Michael Straczynski also changed the rules for TV creators by actively engaging his fanbase online during the show’s production. More »

Sony Just Had a Two Hour PS4 Event With No PS4

After showing us tons of awesome looking games, straight up denied us the console. We have specs , we’ve seen the controller, but we haven’t seen the box yet. Or triangle, or orb, or whatever this non-existant hardware might look like. Oh and no price or release date, either. We don’t even know when Sony will tell us more. Sony stoked our excitement, and there’s no way to be satisfied. What a bummer. More »

Linux 3.8 Released

diegocg writes “Linux kernel 3.8 has been released. This release includes support in Ext4 for embedding very small files in the inode, which greatly improves the performance for these files and saves some disk space. There is also a new Btrfs feature that allows for quick disk replacement, a new filesystem F2FS optimized for SSDs; support for filesystem mount, UTS, IPC, PID, and network namespaces for unprivileged users; accounting of kernel memory in the memory resource controller; journal checksums in XFS; an improved NUMA policy redesign; and, of course, the removal of support for 386 processors. Many small features and new drivers and fixes are also available. Here’s the full list of changes.” Read more of this story at Slashdot.

Lots of Changes for Intel Graphics Coming in Linux 3.9

With the Linux 3.8 merge over, the Intel Linux graphics developers are looking toward 3.9. From a weblog entry by one of them: “Let’s first look at bit at the drm core changes: The headline item this time around is the reworked kernel modeset locking. Finally the kernel doesn’t stall for a few frames while probing outputs in the background! … For general robustness of our GEM implementation we’ve clarified the various gpu reset state transitions. This should prevent applications from crashing while a gpu reset is going on due to the kernel leaking that transitory state to userspace. Ville Syrjälä also started to fix up our handling of pageflips across gpu hangs so that compositors no longer get stuck after a reset. Unfortunately not all of his patches made it into 3.9. Somewhat related is Mika Kuoppala’s work to fix bugs across the seqnqo wrap-around. And to make sure that those bugs won’t pop up again he also added some testing infrastructure. ” The thing I am most looking forward to is the gen4 relocation regression finally being fixed. No more GPU hangs when under heavy I/O load (the bane of my existence for a while now). The bug report is a good read if you think hunting for a tricky bug is fun.

Most Traffic Jams Are Caused By Just a Handful of Idiots

Deep in your heart you know it: there are like two drivers out there on the road that are causing all the traffic jams and one of those assholes is the guy right in front of you. Well, new information collected from hundreds and hundreds of drivers’ cellphones actually backs that up . Sort of. It turns out that it takes very few jackasses to screw things up for everyone.

Mussel Glue Could Help Repair Birth Defects

sciencehabit writes “When it comes to hanging on tight, the lowly mussel has few rivals in nature. Researchers have sought the secrets behind the bivalve’s steadfast grip on wet, slippery rock. Now, a researcher says he has used the mollusk’s tricks to develop medical applications. These include a biocompatible glue that could one day seal fetal membranes, allowing prenatal surgeons to repair birth defects without triggering dangerous premature labor.” Read more of this story at Slashdot.
