I wrote wvdial, netselect, popularity-contest, git-subtree, bup, sshuttle, redo, and several other open source tools. While at the University of Waterloo I founded a company that made Nitix (a Linux-based server appliance) which was bought 10 years later by IBM and is now called Lotus Foundations. I co-founded EQL Data and some other minor startups. I worked for a while at a big company. Now I'm working on Tailscale, a transparent and secure way to make peer-to-peer mesh connections.
