It was 2005, and I felt like I was in the eye of a hurricane. I was an independent performance consultant and Sun Microsystems had just released DTrace, a tool that could instrument all software. This gave performance analysts like myself X-ray vision. While I was busy writing and publishing advanced performance tools using DTrace (my open source DTraceToolkit and other DTrace tools, aka scripts), I noticed something odd: I was producing more DTrace tools than were coming out of Sun itself. Perhaps there was some internal project that was consuming all their DTrace expertise?
