Adding executables to the new Unity launcher

I've started using Spring Tool Suite for Java development using Spring, but when installing it on Ubuntu 12.04, I didn't get an icon on the launcher. The link helps to avoid having to navigate to and run the executable every time, but I had to do some searching to find out how to add them.

Accessing the ServletContext in Tapestry 4.1

We use Tapestry 4.1 at my new gig, so I decided to implement my sandbox webapp with it to improve my understanding; this process has helped me immensely.

In this webapp I have a gallery that is built dynamically based on a listing of files from a directory within the app context. It was a bit of a struggle to figure out how to get access to the servlet context, but it's incredibly easy once you know the incantation.
