Hello. I'm Tim Deegan, a computer scientist and coder, living in Cambridge, England. (If you're looking for the DJ or the weatherman, try elsewhere.)
My email address is email@example.com. I used to do PGP, but have given up on it.
If you send me email, please use plain text.
I'm one of the maintainers of the Xen hypervisor, responsible for x86 memory-management code. I've worked on Xen since 2006, first at XenSource and then at Citrix, who bought XenSource in 2007. I now work on Xen part-time, and spend the rest of my time building interesting data-storage systems.
Once upon a time I was a sysadmin, first in the part of UCD computing services that ran the .ie ccTLD, and then in the Secure Hosting division of Baltimore Technologies.
I am not currently looking for work; I have more than enough jobs, thank you1. If you're a professional recruiter, please don't contact me.
I have a PhD from the University of Cambridge Computer Laboratory, in the Networks and Operating Systems part of the Systems Research Group. While I was there I was also involved in some infrastructure work for the Xenoservers project. For a while I looked at at processor architectures for network nodes, based on all-optical logic, and specifically at how to do sensible instruction scheduling and data layout on systems with delay-line based memory. My supervisor was Jon Crowcroft
Pointless factoid: this gives me an Erdös number of three2.
1. That goes double for City-of-London jobs. I'm not interested in numerical modelling, thanks.
2. One path from me to Erdös:
