The lack of skilled administrators is to some extent a hurdle in the way of companies adopting Linux on the desktop, HP's Linux chief technology officer, Bdale Garbee, said yesterday.

If he can see the predators hiding in the political jungle, he may.

Overstock.com has a saying: "It's All About the O." But for Vice President of Technology Shawn Schwegman and his IT staff, it's all about the SUSE.

Dave's return to the limelight started with his new site, LXer.com. After some preliminary catching up, he finally agreed to do an intervew with me. Out of the Linux spot light, he has created web sites such as Dave's Garden, the largest database of plant listings and images in the world. He admits his passion for Linux, though.

Day eight of aKademy marked the end of the coding marathon. As though restless with their desktop, KDE hackers turned their attention to a tutorial in live cracking, an impromptu demonstration of command line tools, and a brief rootkit panic.

Many of those who contacted us are intimately acquainted with the subject matter, having had personal, first-hand involvement in the process to date. One of those was Yakov Shafronovich, who co-chaired the Anti-Spam Research Group during 2003, when the group was considering this very issue, prior to passing it on to the IETF.

Web services, by definition, are particularly vulnerable to breaches in security. The flow of potentially sensitive data not only between machines, but between enterprises and across untrusted networks, presents the need for special attention to areas such as message confidentiality, message integrity, authentication, and authorization. Additionally, since Web services are well suited to business-to-business communications and cooperation, there should be some way to enforce trust relationships between business partners. Finally, Web services are used not only by humans, but by other Web services as well. The high degree of automation required for interaction between Web services requires well-designed software architectures, preferably built upon well-designed standards.
