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. However, I was doing training and consulting for Sun, helping their customers with system administration and performance.

IEEE Computer Nov/Dec 2004. Last time out we looked at some of the difficulties inherit in automating control systems. Written in 2004, the ideas remind me very much of Mark Burgess’ promise theory , which was also initially developed around the same time. With thanks to Thomas Depierre for the paper suggestion.

And asserted conditions only evaluated if they’re enabled, so any side effects won’t happen when they’re not enabled; they might sometimes perform local side effects, such as to do logging or allocate memory, but the program should never rely on them happening or not happening. Assertions are only about finding bugs, not doing program work.
