This is Jon Warbrick's work home page. I'm the Information Systems Manager in the Online Systems Division of University of Cambridge Information Services (previously the University Computing Service) (Location: N52° 12' 40", E0° 5' 36"; cycle route available). I have particular interests in running and developing services in the web and/or authentication arena.
I can be contacted by mail as firstname.lastname@example.org. I sometimes appear as @jw35 on Twitter and occasionally post to the "Indistinguishable from Magic" blog. Slides from talks that I've given can be found on slideshare, Prezi, and elsewhere on this site. I maintain a collection of more or less interesting bookmarks in Evernote.
My Free/busy Information is available to University of Cambridge Google Apps users. Additional access by arrangement.
Within the University of Cambridge, you can find out more about me from my lookup entry.
This site provides a home for various courses that I've written and/or presented at various times. It also contains an almost-complete archive of slides and other material from various talks that I've given. Beyond this there's a largely uncatalogued collection of other 'stuff':

One is that, while all important enterprises need careful organization, it is the organization that needs organizing, rather then the enterprise.
