The first day of the proper QCon conference started out with Sir Tony Hoare doing a keynote about the difference and overlap between the science and engineering of computing. Fairly interesting, but the questions and answers were much more interesting stuff. One of the more interesting points made by Hoare was that in his view, a full specification is a generalization of testing. After the keynote I started out my track called Emerging Languages in the Enterprise. I introduced this track, doing 15 minutes of talking about my views on programming languages. The slides for my piece can be found here: http://olabini.com/presentations/ELITE.pdf. My talk was made much more interesting by Tony Hoare being in the front row. That made the whole thing a bit more daunting, obviously… =)

I then spent the rest of the day in my track – which was very good. I am very happy with all the presentations, and felt the track was a great success. First of was Michael Foord, talking about IronPython, and how Resolver uses IronPython to create a great product. Some interesting lessons and information there.

After lunch Jonas Bonér talked about Real-world Scala. The presentation gave a good grounding in Scala without looking at all small details – instead Jonas talked about more high level concerns and styles.

After that, Rich Hickey did a great presentation about Clojure. Rich did a great presentation, talking about Clojure from the ground up. It was very well received.

Martin Fowler did a fantastic presentation on ThoughtWorks experience with Ruby. The room was packed for this.

The final presentation in my track was Attila Szegedi talking about JavaScript in the Enterprise. This was also a great presentation, and gave me some new insight into what you could achieve with Rhino.

All in all, the full track was excellent, and all the presentations achieved pretty much what I hoped from them. I learned a lot from all of them.

After the final session of my track, Martin Fowler and Zach Exley did the evening keynote, talking about how technology helped the Obama compaign. Very interesting stuff too. At the end of the day, a very good day at QCon.
