Hi! I'm Laurens, but most folks call me lvh. I'm a Principal at Latacora. If you're interested in building a security team for your startup, you should come talk to us. I do work in information security (particularly cryptography) and distributed systems. My beard solves discrete logs in fields of small characteristic.
I'm a Fellow of the Python Software Foundation, and wear a number of hats at PyCon. These days, I mostly write Clojure. I'm a fan of Haskell and ML. I write C in anger, and am really looking forward to the day where Rust means I will never have to do so again.
