In addition to this blog, you can find me on Twitter and Google+. I occasionally blog at Symbolism, though that site is mostly a paste bin for the DailySymbol Twitter account.
I’ll be speaking at the Snow Unix Event in The Netherlands in a couple weeks and I plan to go to Germany in September. I’ve made a couple trips to California this year and it looks like I’ll be flying out there more often. And of course you can always find me in Houston. If you’d like to meet in person, please let me know.
[Update: The Twitter account @DailySymbol is still online but I no longer post there. The posts from the Symbolism blog have been archived here (mathematical posts) and here (non-mathematical).]
