DTrace Presentation at JavaOne

Thanks to everyone who attended Jarod’s and my talk this afternoon at JavaOne and especially to those who had to go to the overflow room. The rest of the DTrace team and I were thrilled by the turnout — we would never have thought that 900+ Java developers would be so interested in DTrace. We [...]

DTrace in the JavaOne Keynote

In case you missed the DTrace demo during the JavaOne keynote, you can view it in RealPlayer format here. To skip to the DTrace stuff, jump 1:12:30 in. I haven’t actually been able to bring myself to watch it — I’m too self-conscious — so feel free to comment on it. Things to keep in [...]

Open-Sourcing the JavaOne Keynote

This morning I gave a demo of DTrace with the Java agents during the keynote at JavaOne. In the past few hours I’ve had a lot of great feedback from Java developers — we’ve found a bunch of big performance wins already, and I expect we’ll find more this week (remember the DTrace challenge). For [...]

DTrace at JavaOne

I’ll be at JavaOne this week demonstrating the new Java/DTrace mash-up. At Monday morning’s keynote, I get a 100 second talk-within-a-talk (which itself is a talk-within-a-talk). On Monday evening, Stephen, Mike, Bryan, and I (and possibly some other Solaris folks) will be holding a BoF on OpenSolaris, DTrace and what they mean for Java. We’ll [...]

DTrace Insanity at JavaOne

Something kind of crazy is going on. I got a call from Chris; “Check out what we’re going to do at JavaOne,” he said. Here’s the deal: come to JavaOne, bring your Java application (on a usb device or CD or whatever), and we’ll[1] improve your application using DTrace. Or you get a free tchotchke [...]

Comment out of context

The OpenSolaris launch has been pretty fun — I’ve already had some discussions with customers over the source code. Of course, the first thing people seemed to do with the source code is look for references to “shit” and “fuck”. This was titillating to be sure. Unsatisfied with the cheap laugh, ZDNet wanted to draw [...]

Debugging cross calls on OpenSolaris

I think the thing I love most about debugging software is that each tough bug can seem like an insurmountable challenge — until you figure it out. But until you do, each tough bugs is the hardest problem you’ve ever had to solve. There are weeks when every morning presents me with a seemingly impossible [...]
