Submission + - Firefox Memory Hogging Is Due to Fragmentation (pavlov.net)

A beautiful mind writes: It has been long claimed by users that Firefox leaks memory, and on the other hand the developers claimed the number of leaks are minimal. It turns out both groups were right. Stuart Parmenter, one of the authors of the RAMBack extension started investigating and found out that the issue is memory fragmentation. He discovered that while loading about:blank uses 12,589,696 bytes of memory in the test he performed (image), after exercising Firefox with different websites and then clearing the caches with the help of the RAMBack extension the picture is wholly different: "Our heap is now 29,999,872 bytes! 16,118,072 of that is used (up 4,634,208 bytes from before... which caches am I forgetting to clear?). The rest, a whopping 13,881,800 bytes, is in free blocks!"
Supercomputing

Supercomputer On the Cheap 133

jbrodkin writes "You don't need Ivy League-type cash to get a supercomputer anymore. Organizations with limited financial resources are snatching up IBM supercomputers now that Big Blue has lowered the price of Blue Gene/L. Alabama-Birmingham and other universities that previously couldn't afford such advanced technology are using supercomputers to cure diseases at the protein level and to solve equally challenging problems. IBM dropped the price of the Blue Gene/L to $800K late last year before releasing a more powerful model, Blue Gene/P, last month. Sales of Blue Gene/L have more than doubled since then, bringing supercomputing into more corners of the academic and research worlds."
It's funny.  Laugh.

AC = Domestic Terrorists? 519

Miang writes "A video from a recent FOX 11 (Los Angeles) newscast has surfaced on YouTube. In the segment, reporter Phil Shuman investigates so-called "Hacker Gangs" comprised entirely of anonymous users. The segment, which focuses mainly on users at 4chan, 7chan, and 420chan, seems to confuse /b/ raids and motivational poster templates with a genuine threat to the American public. For added FUD, the FOX team inserted an unrelated video of a van blowing up — twice! Presumably, one is intended to equate anonymous posting with domestic terror. The story and video can be found on the local FOX website, so it does not appear to be simply a clever parody." Cringe as you watch this video explain terms like 'LULZ' and show inspirational poster parodies as evidence of the evils of this terrifying "Group".

GameStop Short PS3s For Launch Day 134

GameSpot reports that GameStop will have too few units for preorders on launch day. Employees are being "asked" to wait until the second shipment of consoles to purchase units, to ensure customers can receive what they paid (and waited in the cold) for. From the article: "For launch day, preorders will be filled in the order they were received, and those who had a preorder but are denied a system on day one will receive something for their troubles. GameStop will give those unfortunate customers (as well as unfortunate employees) a free used game or DVD valued at $19.99 or less when they eventually wind up purchasing the system. Those who reserved a system won't need to wait long to find out if they can expect a system on launch day. Starting tomorrow, customers who preordered a PS3 will be contacted personally by phone and updated on the status of their reservation, the rep said."
