|Linux Kernel Version 3.4 Now Available|
|By Zach Walton|
| It's always strikes me with awe whenever a new version of the Linux kernel is released. The hours of work that developers put into this product is just kind of mind blowing especially when you consider that a lot of the work is done by volunteers. With the newest release, Linux is once again moving forward at a pace unmatched by its open source peers.
Linux 3.4 features a few updates to Btrfs. The first is the availability of a new data recovery tool called btrfs-restore. It's worth pointing out that it doesn't repair damaged filesystems, but rather attempts to pull files from damaged filesystems and copy them to a safe location. Btrfs can also support metadata blocks bigger than 4KB again. It can support blocks up to 64KB, but it's recommended that you stick with 16 or 32KB blocks.
Other general improvements for Btrfs come in the form of performance and error handling. The performance has been improved thanks to not only the increased metadata block sizes, but also a reworked Linux page cache and reduced CPU usage. Previous versions [...]

| With Skype now being owned by Microsoft, the company has the advantage of being able to completely overhaul their infrastructure for the betterment of their own and its users' security. The change, replacing its P2P "supernodes" with Microsoft-hosted Linux boxes, would have cost Skype a pretty penny to implement on their own.
Ars Technica got the scoop from Immunity Security's Kostya Kortchinsky who said Microsoft replaced the nodes about two months ago. The old system would use self-described supernodes that [...]

|Every year, the Linux Foundation, a non-profit organization dedicated to the growth of the Linux platform, compiles an annual development report that details the Linux kernel development process. The report covers the work completed through...||The Raspberry Pi is a tiny $25 computer intended for children that sold out to adults wanting to play with it. It really is quite the amazing work of art as far as computers are concerned. It runs on Linux and has a minimalistic design consisting of an HDMI out, USB port, SD card port and an ethernet port.||I love CrunchBang Linux.
