Chemical plants, Linux and dtrace

When my friend from Usti nad Labem (9th biggest city in Czech republic) asked me to present about OpenSolaris at local Linux conference, I got hooked. First, Usti is interesting city (the city is surrounded by beautiful countryside, yet has chemical plants in the vicinity of city center) and I haven't been there for a long time and second, having the opportunity to present about OpenSolaris technologies to Linux folks is unique.

When we (Sasha agreed to go present with me) arrived to Usti we were greeted by slightly apocalyptic weather (see pictures below). The environment where all the presentations took place compensated that, fortunately.

40 minutes to present about something which most people in the room are not very aware of is challenging. The fact that OpenSolaris is open source and it is a home for several disruptive technologies makes that both easier and harder. We have greatly leveraged Bryan Cantrill's Dtrace review video taped at Google for doing second part of the presentation where we demo'ed dtrace. I have even borrowed some of his quotes. I am pretty sure he wouldn't object since his presentations were perused in the past. To make the list of attributions complete, we have substantial material in the first part from Lukas' past presentations about OpenSolaris project.

It's much better to demo the technology than just talk about how great it is (I remember a funny moment in Bryan's presentation where a dtrace probe didn't "want" to fire where Bryan jokingly said "bad demo!" to the screen. I nearly fell off of my chair at that moment.). "So, I have finally seen dtrace in action !" was one of the great things to hear after the presentation.

The "OpenSolaris technologies" presentation can be downloaded here.
