Samsung creates F2FS file system for NAND flash storage, submits it to the Linux kernel

Samsung creates F2FS file system for NAND flash storage, submits it to the Linux kernel

Has the lack of NAND flash storage-optimized file systems been bugging you? Then you've got something in common with Samsung, which has developed F2FS (or "Flash-Friendly File-System") for the memory of choice for mobile devices and its specific "internal geometry." It's based on a log-structured method, but tackles problems associated with older file systems intended mainly for retro, spinning-disk storage. The company isn't keeping its hard work behind lock-and-patent either -- it's gone open-source and submitted the file system to the Linux kernel, meaning you could see it implemented in Android hardware of the future. It's nice to see Sammy contributing code for the greater good, and if you've got the skills to understand it, a low-down of F2FS is available at the source below.

Linux 3.6 kernel released with ‘hybrid sleep’ capability, Google’s TCP Fast Open extension

Linux 36 kernel released with new 'hybrid sleep' capability, filesystem

The last couple of Linux kernel updates have been a bit of a circus, with Android merging in the 3.3 ring and graphics integration on a (noisy) 3.4 center stage. Version 3.6 of the open source kernel has less flashy, more serene features this time, with hybrid standby, a revised file system and other esoteric networking and architectural features befalling the penguin. That sleep mode, which caches the RAM contents to a disk to prevent data loss, has been available for a while now on Windows and Mac machines and will be especially handy on Linux laptops. The so-called Btrfs file system has also been updated (though is still in a developmental mode) and Google's experimental TCP Fast Open extension has been added, along with additional network drivers, more virtualisation options and additional processor support. Sleepwalk to the source for the complete changelog.

Linux kernel 3.4 is out: supports Trinity, Southern Islands, Kepler, Medfield and more

Heavens, it's already time for another Linux kernel refresh. We're now looking at 3.4, which is available for download now. Whereas the last version was all about green robots, this update focuses on support for the latest processors and graphics cards, including AMD's Trinity and Radeon HD 7000-series, NVIDIA's Kepler stack, plus the graphical component inside Intel's Medfield mobile chip. As if that wasn't enough, there are plenty more changes at the source link, along with a serene missive from the man himself.
