Featured Presentation Jacob Salmela with Hopkins High School provided our feature presentation Under Cover Of Shell (Scripting). Take a look at Jabob’s website and his GitHub repository. You’ll find he’s solved plenty of issues with scripting. He introduced us to GeekTool, a desktop information display, which he populates with loads of geeklets. And he got a few chuckles explaining his Single-user Mode Intrusion-Detection System with Star Trek red alert klaxon (see slide 35).
