- Scala Journey: Idioms, Concurrency and Other Rants (Feb 09, 2010)

Well, over the last 2 weeks, I decided to take the full plunge. I?m taking a highly concurrent production application, where power is a very critical component of our application, and rewriting it...... (read more)
- Securing Middleware Products (Feb 08, 2010)
My work is IT architecture, meaning I focus on the early steps of a
project. Once the application is in production, I usually leave it to
systems and production engineers. For example, for JVM fine tuning,
most of the clients I worked for have people that have the right skills
to do that.

Flash has a valid place on the web, and I don't personally see it as an

In my dream, I was in a big white room just as a door was opening and someone was about to walk in. Who was that? That's when I was awakened.
Don't you hate dream interruption? Or Idruption? Quick note, I heard the iPad comes with an Idruption finisher, those guys at Apple are so innovative.
