JavaOne DTrace Session 2006
Jarod Jenson and I presented at JavaOne last week. If you’re interested, here are the slides we used: Admittedly, a pdf can’t capture the scene of Jarod typing in DTrace commands while I futilely try to narrate, but you can run your own demos by checking out this, this, and this.

Two of the DTrace creators (that’s me on the right, and Bryan on the left) apparently square off at the recent OpenSolaris user group meeting at JavaOne. You fill in the bubbles; the funniest response wins nothing but my heartfelt amusement.
DTrace at JavaOne 2006
At last year’s JavaOne, DTrace enjoyed some modicum of celebrity, being featured in a keynote, a session, and the DTrace challenge. The session was attended by about 1,000 people (out of about 10,000 at the conference), and the DTrace Challenge — which promised to find a performance win in Java applications brought to us or [...]
User-land tracing gets better and better

It’s been used to instrument Postgres and Apache, and to add observability into dynamic languages such as Java, Ruby, and php. I recently made a couple of improvements to USDT that I mentioned here [...]
