Comment How to remove deleted data (Score 1) 491

Want to wipe deleted data off a drive? It's really simple, there is a method I always use before making an image of a drive. dd if=/dev/zero of=/location_on_drive Wait for the file to use all the space on the drive then delete it. I use it to make drive ghosts more compressable. Though if you wanted it for privacy you could always source from urandom instead of zero.

Exchange Comes To Linux As OpenChange 249

joesmart writes to tell us that new work on OpenChange and KDE seeks to bridge the gap between groupware compatibility and open source. KDE developer Brad Hards spoke at the Linux.conf.au conference and said the goal of OpenChange is to implement the Microsoft Exchange protocols as they are used by Outlook. "OpenChange has client and server-side libraries for Exchange integration and relies heavily on code developed for Samba 4. It is open source software licensed under the GPL version 3. Hards said more work is being done on the client side and 'we have code for the server,' but estimates another 12 months of development is required to produce an OpenChange server ready for production."

Charter Launches 60 Mbps Service 299

ndogg writes "While other companies are throttling their services, and capping bandwidth, Charter Communications, the cable company, is launching a 60/5 Internet service, starting in St. Louis, MO. It's certainly not cheap, starting at 129.99 per month (add another 10 if it's not being bundled with television or phone.) Currently, it's the fastest down stream speed available, and being a cable company, they potentially have greater reach than FiOS." However, there may be a risk to putting too much money down on this service; Charter Communications as a company faces some serious financial problems right now. As reader Afforess writes, "rumors abound that Paul Allen may just cut his losses and run," by selling the company. (Allen is the majority stockholder.)

Scientists Identify a Potentially Universal Mechanism of Aging 359

cybergenesis2008 points us to a summary of research out of Harvard Medical School in which a set of genes known to affect aging in yeast was found to affect aging in mice as well. The genes, called sirtuins, perform two particular tasks; regulating which genes are "on" and "off," and also helping to repair damaged DNA. As an organism ages, the frequency of damage to DNA increases, leaving less time for the sirtuins' regulatory tasks. The increasingly unregulated genes then become a significant factor in aging. Realizing this, the researchers "administered extra copies of the sirtuin gene [to the mice], or fed them the sirtuin activator resveratrol, which in turn extended their mean lifespan by 24 to 46 percent." We discussed the plans for this research a few years ago.

Talking Web, Memory Aids, and Solar Phones In 5 Years 109

jbrodkin writes "A talking Web, solar technology embedded in windows and cell phones, and the end of forgetting will all come in the next five years, IBM predicts in its third annual Next Five in Five list, detailing innovations that could change our lives in the next half-decade. The other predictions: We will all have digital shopping assistants and, separately, 'crystal balls' to predict our future health. If IBM is right, in five years we'll forget about keyboards and use our voices to surf the Web on solar-powered laptops. DNA profiles will predict our personal health risks, and we'll get automatic reminders to perform daily tasks, generated by digital recording and analysis of our conversations."
