I went to the new Brooks Landing Boulder Coffee Co. last night with Tessah and Jared to see my friend Christi play ukelele. She rocked it for at least and hour and a half seated, fittingly I think, in front of a wonderwoman painting. She played most of the material from her new album, Snakeskin, [...]

Having last attended Shmoocon in 2007, I was glad to see that all the things that made it great ”then” were still present for the 2009 installment: A close-knit community feel. The Shmoo Group’s prolific members are very active in the infosec community and appear to unite many disparate groups within it. The freedom to [...]

On Sunday morning I left Denver for Sioux City Iowa. I drove northeast for a few hours then dropped the hammer through the flat flatness of Nebraska. I arrived sometime after midnight at the home of my elementary-school-era neighbors Tom and Noni. Tom directs an impressive tri-state air ambulance service and Noni hops from city-to-city [...]
