The buzz around the Java world nowadays is the coming up of new scripting language to do development on Java, and DZone has an interesting article Farewell to the 'J' in 'JVM'. I've always been preaching to my friends that the best thing to invest our time in nowadays is not to learn a new language but to learn more about virtual machines and how it works, as programming language is just an abstract tool for us to get our job done quickly, but what going on under the hood is what matters at the end of the day. I'm glad that now people are realizing the potential of Java not as a programming language but as a PLATFORM that you can built anything you can dream of.

The transition is not going to be easy for most people as that's the nature of our open source socio-economic, nevertheless people will realize it and will gladly accept it as part of them sooner than later.

I've added Python-style list comprehensions to the javac compiler. They operate on Iterables, allowing for a delayed-evaluation streaming programming model. A spec, some examples, and a prototype are available.

On its most abstract level, VisualVM is simply a tool for displaying data. By default, it displays data relating to applications, hosts, dumps, and snapshots. However, it could, theoretically, display any data at all (photos, for example), although the intention of the tool is for it to deal with monitoring and management data. The reason that it can work with any kind of data is the fact that its APIs are created with pluggability in mind. Pretty much everything is pluggable and that's the point—VisualVM is intended to cater to all your monitoring/management data needs.
