U Cambridge Computer Laboratory - Xen virtual machine monitor: "Xen is a virtual machine monitor for x86 that supports execution of multiple guest operating systems with unprecedented levels of performance and resource isolation. " It's open source.  OS's must be modified to run under it.  Interesting comparison of performance vs. vmware and user mode linux, and an Oct 2003 academic paper.  Running PostgreSQL or Apache specmarks, vmware runs under 50% of raw Linux and Xen runs 90%.  8:01:44 AM

Maven from Apache: "Maven is a Java project management and project comprehension tool. Maven is based on the concept of a project object model (POM) in that all the artifacts produced by Maven are a result of consulting a well defined model for your project. Builds, documentation, source metrics, and source cross-references are all controlled by your POM. .. The intent of Maven is to make intra-project development highly manageable in the hopes of providing more time for cross-project development."  7:46:22 AM
