This weekend I enjoyed with NTT Hackathon. We developed a Microsoft Kinetic-powered store: you can see objects, consult a catalog via arm swipe, and order 3D prints via hand claps. 3D Printing was powered by OctoPrint after a bad experience with SkyForge. We hope SkyForge will be production-ready in a couple of software-iterations (their lack of a full WebService API is simple to fix).

If you have an application with thousand of beans, you must do unit testing but…Spring testing is boring, belive me. A very complex Spring application usually have a lot of dependency: I had to manage over 3000 beans definitions in a production project right now. Sometimes you want only to test a bit of it, and setting up a complete Spring Context will drive you crazy. To avoid losing mind, my suggestion is to …cheat. Let’see how.

Bash scripting has evolved a lot in the last ten years.

I get used to relay on bash for all normal “data domination” tasks (like file system refactorings, database extraction and reporting and so on) and switching to python/ruby/perl when the complexity gets bigger.
