Cheap GPUs are rendering strong passwords useless
Think that your eight-character password consisting of lowercase characters, uppercase characters and a sprinkling of numbers is strong enough to protect you from a brute force attack? Think again! Jon Honeyball writing for PC Pro has a sobering piece on how the modern GPU can be leveraged as a powerful tool against passwords once considered safe from bruteforce attack. Take a cheap GPU (like the Radeon HD 5770) and the free GPU-powered password busting tool called 'ighashgpu' and you have yourself a lean, mean password busting machine. How lean and mean?

An evolutionary explanation for anorexia?
An evolutionary instinct that told members of migrating populations to move along when their food supply ran out may be a major contributor to modern anorexia nervosa, according to a new theory. When food is scarce and starvation begins, most animals and people demonstrate intense hunger, low activity levels and a single-minded search for food. But, when starved, individuals with a genetic tendency toward anorexia feel sated, full of energy and unfazed by starvation--a set of symptoms described in the DSM-IV, says psychologist and Missoula, Mont. private practitioner Shan Guisinger, PhD, in an article published last year in Psychological Review (Vol. 110, No. 4). "In treating anorexics, I started to wonder if their symptoms could be something that was useful in the past," Guisinger explains. "When nomadic foragers were starving, it wouldn't make sense to hunker down and just not eat. A problematic adaptation

5 FREE Programs to make your computer (slightly) easier to use and look cool(ish)
This is a neat little gizmo that sits on any side of the screen. In its original format, I found it slightly obtrusive (it covered up the tool bars). I used these solutions. Make it too small to obstruct the toolbars (I did this) Put it at the left of the screen (the right has the scroll bar)
UsingTheTerminal
"Under Linux there are GUIs (graphical user interfaces), where you can point and click and drag, and hopefully get work done without first reading lots of documentation. The traditional Unix environment is a CLI (command line interface), where you type commands to tell the computer what to do. That is faster and more powerful, but requires finding out what the commands are." -- from man intro(1)

Shortcuts to move faster in Bash command line - teohm.dev
Nowadays, I spend more time in Bash shell, typing longer commands. One of my new year resolutions for this year is to stop using left/right arrow keys to move around in the command line. I learned a few shortcuts a while ago. Last night, I spent some time to read about “Command Line Editing” in the bash manual.
Why is my Windows PC running out of memory?
I have a four-year-old Windows desktop that frequently runs really slowly with Task Manager showing that 80-90% of the physical memory is being used even when I’m not running any applications. Svchost.exe seems to be the culprit, and sometimes RapportService.exe *32. I did a software spring clean as your column suggested but it didn’t help. My PC is an HP CQ5307UK desktop, with a 2.90GHz AMD Athlon II X3 435 processor and 3GB of memory running Microsoft Windows 7 and Norton Internet Security.
