+ - Samsung Creates New File System F2Fs For Linux & Android->

Submitted by sfcrazy
sfcrazy (1542989) writes "Samsung has created a new Linux file system called F2FS. Jaegeuk Kim of Samsung writes on the Linux Kernel Mailing List: F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead."

I was on UKFSN when I lived with people, but had to switch to a cheaper ISP when I started living on my own. If I could afford it I'd definitely go back, though - proper business-grade ADSL, a /29 subnet, fantastic latency and great customer support (it's run by a geek in his garage).

That was a couple of years ago so it may have changed, but I'd certainly be willing to try them again if I had the chance.

It may be able to withstand static pressures at the ocean's deepest points, but as soon as you start moving you get dynamic pressure from the bow wave at the front. If it was going fast enough, it could easily experience a pressure head of more than 37000 feet at the nose. Plus, craft like this will be built with a decent safety factor, hopefully at least 2.0, so the people inside it don't die if the engineers get their maths wrong.

Noone should be coerced into pleading guilty. Imagine he was innocent, but unfortunate enough to have the evidence against him. Now he either confesses to a crime he didn't commit, or gets convicted of "felony commercial burglary", a crime much bigger than the one he didn't commit.

I was reading the summary thinking "surely a telescope's sensitivity should be measured in arcseconds, and the minimum detectable speed should be in arcseconds-per-second rather than miles per hour." Of course they were talking about bodies moving toward and away from us, rather than across our field of vision, so it's a Doppler effect measurement rather than looking at a picture and saying, "hey! That bit moved!"
