Desktop virtualizers vie for position: If you haven't noticed, we're strong advocates of virtualization here at InfoWorld. Those of you hungry for some insight on the desktop virtualization space would be well served reading Randall C. Kennedy's recent roundup of four competing solutions from big-names like VMware, Microsoft, and Parallels, as well as a potential up-and-comer, InnoTek. In general, Randy observed Desktop virtualizers vie for position: If you haven’t noticed, we’re strong advocates of virtualization here at InfoWorld. Those of you hungry for some insight on the desktop virtualization space would be well served reading Randall C. Kennedy’s recent roundup of four competing solutions from big-names like VMware, Microsoft, and Parallels, as well as a potential up-and-comer, InnoTek. In general, Randy observed some room for improvement across the board: Only one of these solutions scored above an 8. Check out the review and find out why.XenSource vs. VMware: Speaking of virtualization, David Marshall over in the InfoWorld Virtualization Report is keeping a tab on the ongoing battle between the XenSource and VMware camps as they argue over which solution is the superior performer. Well, XenSource is poised to release a white paper later today — which VMware has signed off on — that says, among other things: “Our performance results show convincingly that XenEnterprise 3.2 performs equally well or better than VMware ESX Server 3.0.1 in all but a couple of tests.” David will link to the white paper when it’s available, so stay tuned.Freebase and the Semantic Web: The promise of the Semantic Web has tickled and tantalized the fancy of many a techie, including InfoWorld Strategic Developer Martin Heller. Now Martin has stumbled across a promising building block for the Semantic Web: an ontology, or system of classification, called Freebase, “something like a modifiable database already integrated with a Web application.” To find out why he’s so excited, click on.
