Another unexpected program change at JavaPolis brought us Oracle’s Omar Tazi (director of SOA evangelism and Chief open source evangelist) instead of Marc Fleury in Wednesday’s keynote session.
Unfortunately, a school example of how not to do a presentation. We got an hour-long talk of Omar clicking away on his laptop, showing All-New Oracle product after [...]

I’m being urged to choose sides. Colleagues say I should specialize in either frontend or backend development. I’ve never liked to commit to any specialization. Partly because I’ve always admired the renaissance ideal of the uomo universale who knows and does it all. But also because, when I started out my career, 20 years ago, [...]

When expectations are high, you’re invariably up for some disappointment. Charles and Tom were unable to demo Rails-in-a-war-on-Glassfish; but at least they gave a warning in advance. But I definitely expected something more–or rather something else–from Eric Evans’ university session on domain-driven design (ddd).
The afternoon session on scripting languages went well enough anyway–or at least, [...]

Just arrived in Antwerp, Belgium, for the JavaPolis 2006 conference which starts tomorrow morning. Same venue (Metropolis, where I stopped on the way to pick up this year’s goodies bag), same hotel (Astrid–yeah I know it has a tacky name but it’s really not that cheap). Fortunately, the state of Antwerp’s wireless networking has advanced [...]

Yesterday evening I attended a session on domain-driven design (ddd) at Sogyo’s offices, a nicely converted farmhouse located somewhere in the center of Holland. I was amazed to hear Ruby and Rails being used as an example of domain-driven development. One of the presenters even claimed that Dutch Rubyists Remco and Michiel (who reached 2nd [...]

So much to do in this hot and cold summer (July: 36 degrees, August: 16 degrees) and so little to blog about. In case anybody wonders, this is what I’ve been up to lately.
Gone back two years in time: After I finally left the WebLogic project in May, a little later than planned, I was [...]

Twice a year the Dutch Java User Group organizes a mini conference with sessions about Java, JEE, and everything related. In spring this day is called J-Spring (which has nothing to do with the Spring framework), in fall it’s called J-Fall. While preparing for RubyEnRails 2006 I thought it would be a good idea to [...]

It’s been almost two weeks since RubyEnRails 2006, the first big Dutch/Belgian Ruby and Rails event. I think it’s safe to say that it was a success. Over 100 visitors showed up; we had an excellent venue and six very entertaining sessions:

Frank Oxener (Agile Dovadi) gave a live demo of building a Rails app and [...]

For some mysterious reason, there seems to exist a correlation between the temperature outside and the amount of entries on my blog. A sudden and long-awaited spell of sunny weather has been making Holland happy for more than two weeks now. In the evenings I am faced with the choice between sitting outside for a [...]

After installing and playing with JRuby a few days ago, I started wondering if it would be possible to access an EJB from a JRuby script. After all, the Java code to call an EJB is purely client code, only communicating with an application server over an HTTP-like protocol (HTTP-like in BEA’s case, anyway). At [...]
