Introducing your guest host, PingI'll be in Ecuador for the next two weeks, and Ka-Ping Yee has graciously agreed to post here in the meantime. I'm thrilled. Ping is a Ph.D. student in CS at Berkeley, where he's making better UIs for voting machines, and besides being a brilliant illustrator, outspoken proponent of social justice issues, and prolific get-stuff-done kind of guy, he's an all-around inspirational human being. He can also be found at his blogs, Usable Security and Without Loss of Generality.
Treat him well. I'll be back later this month with bug bites and stories.
