+ - KDE's Aaron Seigo wants his minions to play nice->

Submitted by mrvanes
mrvanes writes: There has been some turmoil about a nasty regression in KDE 4.7.0 in this bugreport until Aaron Seigo decided that enough is enough and closed the bug for not living up to his expectations of good conduct. This wouldn't be too bad if this bug wasn't the best description of the problem, had the most votes and if he would have pointed to the 'other' bug this was supposed to duplicate. He didn't. He invalidated the bug, refuses to disclose the original bug and his fellows leaders do the same for him. Is this what Open Source is headed towards when One rules them all?

+ - Increased Performance In Linux With zRam (Virtual ->

Submitted by Anonymous Coward
An anonymous reader writes: While trying to optimize the elementary OS performance, Sergey Davidoff stumbled upon a project called compcache that creates a RAM based block device which acts as a swap disk, but is compressed and stored in memory instead of swap disk (which is slow), allowing very fast I/O and increasing the amount of memory available before the system starts swapping to disk. compcache was later re-written under the name zRam and is now integrated into the Linux kernel.

Sergey wrote a script that automatically adapts to the amount of memory in the system and automatically scale across several CPUs or CPU cores so this is now very easy to use. This script should help older systems stay responsive while using applications that need a lot of RAM.

astroengine writes: "The anammox — for anaerobic ammonium oxidation — bacterium is a curious microbe. Remarkable for not needing oxygen to survive, it also has the ability to turn ammonia into hydrazine — a rocket fuel. Sadly, NASA won't have much of a use for it, the amount of hydrazine produced is minuscule. Regardless, as ammonia is found in urine, expect dozens of rocket-powered pee jokes."

Aging Reversed In Mice 554

Hugh Pickens writes "The Guardian reports that scientists claim to be a step closer to reversing the aging process after experimental treatment developed by researchers at Harvard Medical School turned weak and feeble old mice into healthy animals by regenerating their aged bodies. 'What we saw in these animals was not a slowing down or stabilization of the aging process. We saw a dramatic reversal – and that was unexpected,' says Ronald DePinho, who led the study. The Harvard group focused on a process called telomere shortening where each time a cell divides, the telomeres are snipped shorter, until eventually they stop working and the cell dies or goes into a suspended state called 'senescence.' Researchers bred genetically manipulated mice that lacked an enzyme called telomerase that stops telomeres getting shorter causing the mice to age prematurely and suffer ailments, including a poor sense of smell, smaller brain size, infertility and damaged intestines and spleens. When the mice were given injections to reactivate the enzyme, it repaired the damaged tissues and reversed the signs of aging raising hope among scientists that it may be possible to achieve a similar feat in humans – or at least to slow down the aging process."

Is That "Sexting" Pic Illegal? A Scientific Test 711

Frequent Slashdot contributor Bennett Haselton writes " Amid the latest 'sexting' controversy, here is a proposal for a scientifically objective method to determine whether a picture constitutes child pornography. This is a harder problem than it seems, but not for the reasons you'd think. And it raises questions about how the same scientific principles could be applied to other matters of law."
