And Simon is a great speaker. I was a bit disappointed with Doris though. I didn't like the way she treated the audience as complete...hmm...how to put it..."clueless". No, Ruby as a calculator is not really show-casing the power of the language! And a web service through annotations? Ok, who was really impressed with those "news" in 2008?? The code was even broken (she forgot to add the @WebMethod annotation...). I also enjoyed the slide with all the technologies working together with Glassfish. I noticed PostgreSQL, Oracle, even Derby, but MySQL? Nowhere! A coincidence? I also hoped Heinz showing something newer :-/. Indeed, a Q/A session was much needed. A couple of points: - Using "this" as a monitor is *not* bad practice. It allows for extending the locking protocol, and it was the way to go to implement a "putIfAbsent" method in Java 1.4 with Collections.unmodifiableMap, which indeed uses "this". - Making doubles/longs volatile just not to get strange "split" values, because updating them is not atomic, is pointless. The code that showcases the problem (in theory at least) is already broken for multi-threaded access anyway - it showed updating a long value from two threads with no synchronization whatsoever. Damn, I missed the food, we thought there weren't any and went outside! I enjoyed very much Simon’s presentations, and especially, duh, the one for Solaris, ZFS, and all that. – it was great!
