Computer simulation, programming, software, technology, research, and more (since 2007)
Simics and other simulation solutions are a great way to add more variation to your software testing. I have just documented a nice case of this on my blog at the Intel Developer Zone (IDZ), where the Simics team found a bug in how Xen deals with MPX instructions when using VT-x. Thanks to running on Simics, where scenarios not available in current hardware are easy to set up.

FLOSS Weekly recently ran an interview with the creator of the Xen project, Ian Pratt from the University of Cambridge (and now working for Citrix since they bought Xensource). Since I happen to like virtual things, even the so-much-talked-about-it-hurts IT/server/desktop virtualization world this was a must-listen. It was a good show, but lacking some in the humble background department.
