After QCon London 2008

This week has mostly been taken up with QCon London. I spent most of Monday, Wednesday, Thursday and Friday here, and I thought that I'd take the opportunity to write up some of my impressions and thoughts about the sessions I attended.

First, in general the conference definitely didn't disappoint me. It held at least as high standard as I had expected from earlier QCon and JAOO conferences. Solid speakers, a wide range of exciting topics and lots of interesting people made for a grade A conference.

I started out on the Monday with listening to my colleagues Neal Ford, Rebecca J Parsons and Martin Fowler give a tutorial on domain specific languages. I've seen bits and parts of this tutorial before, but seeing as the three speakers are working on evolving it to a full and coherent "pedagogical framework" for teaching DSLs, the current presentation had changed quite a bit since the last time. I really liked it and I recommend it to anyone interested in getting a firm grasp about what DSLs are. Having Rebecca talk about external DSLs in the context of parsers and grammars makes total sense, and the only real thing I would say was a problem was the time allotted to it. Her part of the subject was large enough that 75 minutes felt a bit rushed. Of course, I don't see how Martins or Neals parts could be compressed much more either, so maybe the subject actually is too large for a one day tutorial? Anyway, great stuff.

For several reasons I decided to spend the Tuesday working from the office instead of attending tutorials again.

During the Wednesday I mostly spent my time in the exhibition hall, talking to people and doing general networking. For some reason the tracks I was least interested in had all been scheduled on the same day, so I was lazy and worked on other stuff in the ThoughtWorks booth.

The evening keynote on Wednesday by Martin Fowler and Jim Webber was hilarious, and also managed to get a quite important message across. I had a good time.

Thursday started the session attending for me, beginning with Markus Völters presentation of XText in the DSL track. Highly informative and something that I'll keep in mind if I see something that would be benefit from it. The approach is definitely not for all problem domains, of course.

After that. Venkat Subramaniam gave a talk about how to blend dynamic languages with Java. This talk was useful in explaining why you'd want to do something like this, and why it's such a powerful technique. It also served to set up my talk - which was next in that track - about evolving the Java platform. My talk went well, but I had the timing for it really messed up, so I ran out of material 10 minutes earlier than I expected. Neal Gafter was in the audience and helped out with some corrections during the talk. =)

Finally I headed back to the DSL track and saw Avi Bryant talk about DSLs in Smalltalk and then Magnus Christerson and Henk Kolk talk about the Intentional Workbench. Lots of neat stuff in both of these presentations.

Then there was the speakers dinner... Lots of interesting discussions with lovely people. =)

And then, more quickly than I had expected, the final day of QCon arrived. Me as a Ruby person and programming language nerd had quite a good selection of tracks. I ended up seeing Ted's presentation on F#, which made me feel: wow! Microsoft took ML and did exactly what they've done to all languages on the CLR - added support for .NET objects in the mix. The talk ended with a quite strange discussion about whether F# actually helps with concurrent programming or not, and why a functional programming language has primitives that allow you to have mutable state.

After that I did my talk in the Ruby track, talking about more advanced things regard JRuby. It ended up being great fun, and I spent lots of time in the talk answering questions and showing how seamlessly things work with JRuby. I ended up eating up 10 minutes of everyone's lunch time, but I had a great time and I thing most in the audience had too.

Feeling happy and finished with my contributions, I ended up in the Erlang talk by Joe Armstrong. It gave a quite good overview of why Erlang was created and how it solves some of the problems in that particular problem domain. There is no doubt that Armstrong is an entertaining talker, but his buffoon image gets a little tiring and repetitive after a while. Some of the things that interested me in the talk was missing too. He started out saying that Erlang solves a particular problem, but then expanded that into something that sounded like "Erlang should be used for everything, everywhere". I tried to ask a question related to that, but the answer didn't really go in the direction I was interested in.

I stayed in the languages track and saw the introduction to Scala, which is always fun, except that I'd already learned most of the things showcased. The most interesting about the presentation was the audience interest and questions.

Finally I realized that my contributions were not over at all, since I'd agreed to be part of the closing Ruby panel. This ended up revolving quite a lot around the question whether Ruby and Windows ever will be a good match, if this is important, and if we really want to push Ruby into all kinds of environments.

The closing panel were OK, but nothing special. It ended the day on a good note, but at that time I was tired enough to fall asleep in my chair. For some reason this always happens that last day of conferencing.

Anyway. I had a great time and I look forward to being back the next time. I can definitely recommend QCon as one of the best conferences around in this industry.

Yep, you're absolutely right that your JRuby presentation was well received. For me it was one of the highlights of the conference. :-)

Happy sa...
