Managing a MongoDB deployment? Take a load off and live migrate to MongoDB Atlas, the official automated service, with little to no downtime.

James Gosling introduced a brief view on the Java world this morning at Zürich. It is always a joy to listen a successful geek onthe stage, probably one of the most successful geek of the last few decades. He talked about the modern Java world and about our forever perspective (following his words, forever == the next ten years). Here it comes the highlights:

  • Statistics, specially on smart cards. 15M downloads/week
  • Learn once, work everywhere
  • Tiny little word of web apps
  • Big networking based systems, from the Brazilian healthcare system to eBay, mobile platform, games, etc.
  • JVM: the integration hub - different languages, different scripts, all together in a same JVM.
  • Glassfish V3 highlighted, spdecially by its modularity and profiles support. Developer friendly, supporting all major IDEs, rapid development features and support for different languages and platforms. Gosling demonstrated briefly the major features of Java EE 6, like EJB 3.1 and hot deployment.
  • Netbeans 6.7 has its share of the session and the confessed eMacs lover did a good merchandising on the main features of the SUN IDE. Breakpoints inside devices like mobile phones and robots were highlighted, speciall from the nice presentations of the robots competition during the recent JavaOne. The integration between Kenai and Netbeans was a good news for me.
  • Kenai == cloud development
  • Real time world: physical systems required more reliability - determinism X throughput
  • SunSpot and Sentilla received a chunk of exposition, with comments about intelligent mashups between micro components communicating between each other.
  • LincVolt - the car - was again on the stage, a wonder of engineering and creativity moved by eletric bateries.
  • Java low performance myth dismissed - GC much faster than malloc/free. Dynamic compilation beats static.
  • Multithread, multicore - Moore's law: transistors, not GHz. Today machines are four cores, in few years
  • JDK 7, nio2, modularity, dynamic languages, swing app framewok, performance.
  • The web become the face of the enterprise, and now we have the new JavaFX.
