Memristors -- the fourth passive component type after resistors, capacitors and inductors -- were postulated in a seminal 1971 paper in the IEEE Transactions on Circuit Theory by professor Leon Chua at the University of California (Berkeley), but their first realization was just announced today by HP.
Admit it -- you put off your holiday shopping this year and now it's crunch time and you don't know what to get everyone on your list. Because we feel your pain, we've put together a last-minute shopping guide with ideas for some of your geekiest friends.
The Open Source Technology Center (OSTC) at Intel has launched a Web site, LessWatts.org, to help Linux users maximize power savings. The site hosts several open source projects, and shares tips and tricks to help optimize power consumption on hardware from portable devices running on batteries to large data centers.
Fully-functional video drivers -- ones capable of handling 3-D acceleration -- remain one of the weak points of free software. The Free Software Foundation has declared them a high-priority project. Meanwhile, some distributions and even more users have resorted to using the proprietary drivers offered as free downloads by card manufacturers. One of the main projects attempting to provide complete, free drivers is focusing on developing the Avivo driver for the R500 and R600 cards from AMD/ATI, so-called after a specification first introduced in this line of cards. According to Jerome Glisse, who coordinates the development of the driver, progress is being made in the project, and "maybe by the end of this year, we might have some 3-D acceleration."
Nokia researcher Jamey Hicks recently proposed a Open Source Hardware License (OSHL) for approval by the Open Source Initiative (OSI). Is there a need for a hardware-specific license? If so, what makes hardware different from software?
You don't need to be a super-geek to start diagnosing hardware problems. Diagnostics is an art. Specifically, it's the art of determining the source of a problem and troubleshooting a solution. No matter how good you are at diagnostics, the right tools in your hardware bag can make you better.
In the '70s TV show "Happy Days," the character Fonzie was so cool that he could make a dead jukebox play just by giving it a thump in the right spot. If Fonzie were working on computers today, he'd probably use some of these tricks for getting a reluctant hard drive to come across with its data.
