Five years to commercial nanotube transistors?

Researchers in Japan have come up with a new transistor manufacturing technique that they claim will squeeze the best performance enhancements out of carbon nanotubes, without losing the on/off ratio of a good semiconductor.The Nagoya University researchers say they have demonstrated flexible integrated circuits that "are capable of sequential logic" - a first for a transistor made from carbon nanotubes.

How long should a Windows 7 upgrade really take?

How long does it take to upgrade from Windows Vista to Windows 7? Last weekend, several leading tech websites zeroed in on one alarming snippet of data that a Microsoft tester published on his Technet blog: With the right combination of hardware and data, a Vista-to-7 upgrade can take more than 20 hours. That data point leaves plenty of room for snark and trepidation. But does it actually represent performance that you’re likely to encounter in the real world? I've got the real story.

Samsung's NX hybrid digital cameras unveiled, bridging gap between dSLR and compact point-and-shoot

Just a day before the official start of PMA 2009, electronics giant Samsung has announced its new NX Series, a new family of hybrid digital cameras that offer the performance and image quality of a dSLR and the portability and convenience of a compact point-and-shoot.Like conventional digital SLRs, the NX Series utilizes an APS-C sized image sensor, providing a much larger surface area to gather light and produce higher-quality images.

Motorola MC75

Enterprises looking to deploy a rugged, versatile mobile device will be impressed by the Motorola MC75's range of features. However, you pay a premium for smartphone functionality in a hardened form; this phone is not only tough, it is massive to the point of being unwieldy.

Fixing Windows Vista, Part 5: Faster, smarter search

In previous installments of this series, I discussed the virtues of a clean Vista install, some useful User Account Control workarounds, top tools for troubleshooting, and the wisdom of shutting off Windows system services. Today’s fifth and final installment is a little different from its predecessors. It focuses not so much on fixing what might be broken, but rather on taking advantage of a feature in Windows Vista that has the potential to transform the way you work. Through the years, I’ve tried just about every third-party desktop search utility for Windows. But I threw them all away after a few weeks of using Vista’s built-in Windows Search capability. In this post, I’ll explain how Windows Search works, how to monitor the SearchIndexer service to avoid potential performance problems, and how to speed up indexing operations on the fly. I'll also point you to an update that every Windows Vista user should install right now.

Cosmic threat to tomorrow's computers

Intel's first two billion transistor processor, details of which appeared yesterday, is quite the beast. Tukwila is four cores of 2GHz Itanium embedded in 30 megabytes of on-chip cache, together with Intel's next-generation memory controller/cross-point interconnect - which, as any supercomputer designer will tell you, is as important as the details of the rest of the logic.
