Last Tuesday it was our third edition of the Paris JUG and I have to say, it was great. First of all, we had to change our venue. The first place where we held our two first meeting was able to fit 35 people. It was time to change. Indeed, on Tuesday we were 84 ! And it was an english session. We had the pleasure to have Kirk Pepperdine talking about performance (slides to come soon). It was our first non-french speaking presentation, and it worked out well. People loved it and asked many question (maybe French people are not that bad with English ;o) \

Kirk talked for more than 3 hours. Ponctuating his speech with personal stories, experience, jokes, code puzzlers and throwing goodies at people each time a question was answsered. It was a very interested "nothing" talk (as Kirk mentioned). Kirk started with a first slide saying "all I'm gonna say in this presentation is wrong". It wasn't a "dos and donts" on how to tune your java application, but more about what's going on with performance in java and what is the future going to look like. Java was created more than 10 years ago for single core processors. Java SE brought easy threading to every developer. Java EE brought easy distributing to every developer. Developers don't have to know how the GC or JIT works. That might change with multi-core processors arriving. Following that Moor's law (not about how many transistors you can put in a chip but more how many cores you can have in a chip), "in 10 years a desktop will be running 1000 cores". How will we program with such a high parallel computing architecture ? Do we have to change language ? Do we have to change jobs ?

Kirk loves puzzles, and he did many of them. That was great. The most disapointing one was when he showed us that String are not that immutable. That was sad. He threw many t-shirt, many goodies, two books that Aaron Houston (Sun) sent to our JUG (thanks Aaron) as well as some JetBrains T-shirts and Valtech stress balls. That's why the talk was long, plus many questions... really good. \
