Microsoft executive Ty Carlson spoke about the future of Windows recently during a panel discussion at the Future in Review 2007 conference held in San Diego, California. Carlson said that future versions of Windows would have to be 'fundamentally different' in order to take full advantage of future CPUs that will contain many processing cores. "You're going to see in excess of eight, 16, 64 and beyond processors on your client computer," said Carlson, whose job title is director of technical strategy at Microsoft. Windows Vista, he said, was "designed to run on one, two, maybe four processors."

At its 10th anniversary and after a period of uncertainty for the RPM community, together with a new roadmap towards version 5.0 the project environment of the popular Unix software packaging tool RPM Package Manager was relaunched under the domain rpm5.org by the newly formed RPM project team, further on lead by RPM's primary developer Jeff Johnson. The primary goals of RPM 5.0 are the additional support for the XML based archiving format XAR, an integrated package dependency resolver, further improved portability and extended cross-platform support. Note: Please note that rpm5 is a fork of the 'real' rpm project.

"Recently I had a chance to spend some time with Fujitsu's P7230 ultraportable notebook. With a 10.6" LED-backlit LCD and a weight of less than 3lbs the system is just what many mobile fanatics are looking for, but such portability comes at a price. The P7230 is powered but a 1.2GHz Intel Core Solo U1400 processor, something that is great for the battery life, but does not have the power of its Core 2 Duo brethren. The single-core, low-voltage processor works well much of the time but chokes under the load brought on by intensive programs as well as multi-tasking. In attempt to get the most possible from the P7230 I decided to completely remove Vista in favor of Ubuntu 7.04."

Alex Ionescu, one of the lead developers behind the ReactOS project, has published a detailed article on the XP/Vista application compatibility system. "For the last few days, I've been intimately becoming aquainted with a piece of technology in Windows XP and Vista that rarely gets the attention it deserves. It has raised my esteem and admiration towards Microsoft ten fold, and I feel it would be wise to share it, publicize it, and then of course, find (positive) ways to exploit it to turn it into a powerful backend for various purposes."

"A startup in Alameda, Calif. plans to release a kind of holy software grail the third or fourth week of June. Lina said its dual-licensed Lina virtual Linux machine will run more or less normal Linux applications under Windows, Mac, or Linux, with a look and feel native to each."
