Xen PV network driver
I haven’t used Xen HVM until recently. When I was at Amazon and hanging with the Xen provisioning folks, I recall complaints about the performance of network drivers on HVM instances.

IronRuby stuff
I’ve been doing some work with the DLR team at Microsoft and the community of F/OSS developers they’ve inspired on IRC & the mailing lists. I’m providing a virtual host that is being used to perform continuous integration on Debian sid. The current status is here: http://twitter.com/IronRubyCI Maybe we’ll make an IronPerl one of these…

Invested in CTXS
I just had my first vesting in work stocks. I sold a few and re-invested some of the proceeds in Citrix, who plans to purchase XenSource, the employer of Keir Fraser, Tim Deegan, James Bulpin and Ian Campbell, the primary contributors to the development branch of the xen source tree for the last month, and…
