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.

RIM licenses Microsoft’s exFAT file system to stuff extra-large files into BlackBerry devices

BlackBerry 10 home screen

RIM has big ambitions for media on BlackBerry hardware -- really big. Accordingly, it just reached a patent licensing deal with Microsoft that lets it use the exFAT file system on "certain BlackBerry devices." We have a hunch that's a reference to future BlackBerry 10 phones and tablets rather than retrofits of existing (and likely incapable) mobile gear. The move will let any devices that do recognize exFAT handle much larger files, such as long videos, in addition to streamlining transfers between computers and other gadgets. The conditions of the deal haven't been given out, but we suspect RIM's negotiations with Microsoft were on more voluntary terms than those faced by Android supporters.

CHKDSK is changing how it works (step 1 of 1) 56 percent completed…

CHKDSK is changing how it works (step 1 of 1) 56 percent completed...

PC users of a certain age will be all too familiar with defragging and disk checking, normally as a last-ditch attempt to reinvigorate a flagging or faulty system. Fast-forward to 2012, and Microsoft is reassessing the role of the whole NTFS health model for the modern world (well, Windows 8 at least). It turns out that these days actual corruptions are rare, but people still like to run chkdsk just in case -- or out of habit. In the old approach, health check was either happy or unhappy, and the machine was taken offline for as long as was needed to fix. Even with optimization and improvements in later versions, the galloping sizes of hard drives has swallowed up much of the benefit. In the redesigned model there are four states: healthy, spot verification needed, scan needed and spot fix needed. In any of these states, the system remains online, with the user deciding when to restart if a fix is needed. The reboot process should also be much quicker, with the spot fix already targeted. Advanced users can go a stage further and invoke the spot fix while still online for sections of the disk not in use. The proof, of course, is in the pudding, but anything that involves less death-staring at a disk check is a good thing in our book. Hit the source for a blow-by-blow breakdown.
