Submission + - Samsung Creates New File System F2Fs For Linux & Android (muktware.com)

sfcrazy 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!"

I've just had my big mug of coffee, but obviously it hasn't reached my brain yet :)

Robotic Mold 118

Canis Lupus writes to mention that researchers from the University of West England are designing the world's first biological robot, constructed from mold. The robot, "Plasmobot," will be created using vegetative slime mold called plasmodium (Physarum polycephalum) that is commonly found in forests, gardens, and most damp places in the UK. "This new plasmodium robot, called plasmobot, will sense objects, span them in the shortest and best way possible, and transport tiny objects along pre-programmed directions. The robots will have parallel inputs and outputs, a network of sensors and the number crunching power of super computers. The plasmobot will be controlled by spatial gradients of light, electro-magnetic fields and the characteristics of the substrate on which it is placed. It will be a fully controllable and programmable amorphous intelligent robot with an embedded massively parallel computer."
