Smart Open Spaces Powered by Low-Cost Computers - Jorge Hidalgo y Julio Palma v1.0

Speaking at JavaOne 2015 San Francisco!

This year I’ve been selected to give one talk at JavaOne 2015 San Francisco, titled “Smart Open Space Powered by Java ME, Java SE and Single-Board Computers”, along with my good friend Julio Palma (follow him on Twitter @restalion).

If you are interested in IoT stuff, like to play with embedded devices (Raspberry Pi, BeagleBone, etc.) and would like to see a fine reference platform for Smart Open Spaces (offices, department stores, museums, airports, etc.), you are more than welcomed to join us.

More information about the session and schedules will be available here soon!

Why I Prefer Grails For Rapid Scaffolding of New Apps

There are many good frameworks out there, but the one I prefer for quick demos, simple applications and rapid scaffolding is Grails. Why? Simply put – with just a few lines of code you have a fully functional application: user interface, controllers, data validation and persistence.

But Grails is much more than a tool for quick prototypes. It is a fully featured platform based on the rock solid foundation of Spring, Hibernate and other enterprise-grade frameworks. Plug-ins can be added any time and they will seamlessly add new features to the application.

Grails uses Groovy as its primary programming language, but as it runs on the Java Virtual Machine, you have full access and interoperatbility with any existing Java library. Tooling support is also excellent, both from command line and from IDEs like Eclipse or IntelliJ IDEA.

If you think that the above paragraphs are just hyperboles from an enthusiast fanboy, continue reading and experiment for yourself how easy is to build a new app from scratch.

Speaking at JavaOne 2014 San Francisco!

This year I have been honored to be selected to speak at JavaOne 2014. Awesome news! I’m excited for this opportunity to speak at possibly the larger Java developer conference in the world.

The session that was selected is CON2013: Code Generation in the Java Compiler: Annotation Processors Do the Hard Work. This session is largely based on my work around Annotation Processors as a driver for code generation.

It is really a pleasure to see that what was an experimental work three years ago, matures and get the attention of the JavaOne commitee.

So, if you happen to be at JavaOne, don’t miss the opportunity and come to the session! See you there!
