Goodbye petabytes and exabytes, hello zettabytes! : " In a relatively humorous and sarcastic post , blogger Paul McNamara looks at a recent news release from EMC and attempts to understand, and help us understand, just how big a zettabyte is. Here are three analogies from the EMC article: “The digital information created by every man, woman and child on Earth ‘Tweeting’ continuously for 100 years.” “75 billion fully-loaded 16 GB Apple iPads, which would fill the entire area of Wembley Stadium to the brim 41 times, the Mont Blanc Tunnel 84 times, CERN’s Large Hadron Collider tunnel 151 times, Beijing National Stadium 15.5 times or the Taipei 101 Tower 23 times.” “A full-length episode of FOX TV’s hit series 24 running continuously for 125 million years.” As McNamara points out, these analogies are oftentimes outside the scope of what the normal human — even the normal IT person — can fully grasp. For example, the “tweeting” example requires the knowledge of how many h...

Windows Error Message Grabber : " Windows XP only software Error Report Grabber is an indispensable tool for users who frequently experience error messages in the operating system. Many error messages in Windows are displayed in windows without the option to copy or process the information easily. It is for instance not possible to copy the error message title to research the error on the Internet. This has to be done manually by the user. Error Report Grabber is a portable software that can grab the information from open Windows error messages to provide the user with a text version of the information that can be copied easily. The process is semi-automated. The user needs to start the Error Report Grabber application if a Windows error message is displayed on the screen. It is then necessary to enter the first words of the error report title and error text so that the program can identify the correct window. A click on the Find Report button scans all open windows for the ...

Tabjacking: a new and ingenious phishing attack : " Filed under: Internet , Security , Browsers By now, all but the most geriatric Web users know about phishing. Usually it takes the form of a seemingly-official email from a bank or other money-related Web service. Most of the time these attacks are painfully obvious -- but what if you removed the email attack vector? What if you removed those daft give-away URLs? What if the phishing attack was pure, seemingly-benign JavaScript that's invisible to all but the most judicious of Web users? That's exactly what 'tabjacking' does. Open Aza Raskin's proof of concept in a new tab. Admire the sample code. Now, change tabs, wait five seconds, and then watch in horror as his site seemingly becomes GMail. Malicious JavaScript injection isn't a new thing -- and this particular exploit only works in Firefox (and partially in Chrome) -- but you have to admit it's pretty damn scary. It's certainly o...
