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.

ATLAS Meteor Tracking System Gets $5M NASA Funding

An anonymous reader writes “After a huge meteor recently exploded over Chelyabinsk (population 1,130,132), Russia, NASA has approved $5 million for funding for ATLAS project (Asteroid Terrestrial-impact Last Alert System). From the article: ‘”There are excellent ongoing surveys for asteroids that are capable of seeing such a rock with one to two days’ warning, but they do not cover the whole sky each night, so there’s a good chance that any given rock can slip by them for days to weeks. This one obviously did,” astronomer John Tonry of the Institute for Astronomy at the University of Hawaii told NBC News Friday.'” Read more of this story at Slashdot.

First Bionic Eye Gets FDA Blessing

coondoggie writes “The U.S. Food and Drug Administration today approved what it says is the first bionic eye, or retinal prosthesis, that can partially restore the sight of blind individuals after surgical implantation. The Argus II Retinal Prosthesis System includes a small video camera, transmitter mounted on a pair of eyeglasses, video processing unit (VPU) and an implanted artificial retina. The VPU transforms images from the video camera into electronic data that is wirelessly transmitted to the retinal prosthesis.” Read more of this story at Slashdot.

Unscrambling an Android Telephone With FROST

Noryungi writes “Researchers at the University of Erlangen demonstrate how to recover an Android phone confidential content, with the help of a freezer and FROST, a specially-crafted Android ROM. Quite an interesting set of pictures, starting with wrapping your Android phone in a freezer bag.” Read more of this story at Slashdot.

Britain Could Switch Off Airport Radar and Release 5G Spectrum

judgecorp writes “Britain is considering switching off air traffic control radar systems and using “passive radar” instead. A two year feasibility study will consider using a network of ground stations which monitor broadcast TV signals and measure echoes from aircraft to determine their location and velocity. The system is not a new idea — early radar experiments used BBC shortwave transmitters as a signal source before antenna technology produced a transceiver suitable for radar — but could now be better than conventional radar thanks to new antenna designs and signal processing techniques. It will also save money and energy by eliminating transmitters — and release spectrum for 5G services.” Read more of this story at Slashdot.

Turning a Kindle Fire HD Into a Power Tablet

jfruh writes “The Kindle Fire HD is in theory a powerful device at a reasonable price — but its Android-based OS is so oriented towards Amazon’s ecosystem that it can be tricky to unlock its full potential. Still, with a little savvy you can get underneath the covers, improving battery life, getting full access to cameras and other devices, and even listening to music you’ve purchased through iTunes.” Read more of this story at Slashdot.

Printable AR-15 Mag Gets More Reliable; YouTube Pulls Video of Demo

Wired reports that the 3-D printed AR-15 magazine from Defense Distributed we mentioned a few weeks back has been improved through design, and is now robust enough to last through firing (at least) several hundred rounds, rather than fewer than a hundred as in the previous iteration. CNET says the video demonstration on YouTube was first yanked, then restored, but as of now seems to have been yanked again. Read more of this story at Slashdot.

Ants Use Sound To Communicate

sciencehabit writes “A new study shows that ant pupae—a stage between larvae and adult—can communicate via sound, and that this communication can be crucial to their survival. The young insects have a specialized spike along their abdomen that they stroke with one of their hind legs, similar to dragging the teeth of a comb along the edge of a table. This noise serves primarily as an emergency beacon, allowing the ants to shout for help when being threatened by a predator.” Read more of this story at Slashdot.

KDE 4.10 released with leaner Air theme, more love for mobile devices

There are plenty of Linux desktop environments to choose from , but if KDE has a special place in your heartware, you’ll be pleased to know its first 2013 update is out. Making the jump from 4.9 to 4.10 brings various tweaks to Plasma Workspaces, including upped support for high-res displays, a streamlining of the default Air theme, and plenty of behind the scenes adjustments. All running software can now be controlled through a common menu system, search indexes happen faster, and the new Nepomuk Cleaner will help rid those clogged drives of unnecessary data. In addition, printer management has been improved, and the enhanced Dolphin file manager communicates more freely with mobile devices. A thorough, lovingly crafted changelog is available at the source link below, but if you’re particularly fond of surprises, then head straight for the download. Happy upgrading!
