This talk aims to scratch the surface of what is known as the “Open Source Long Tail”, showing off some of the most interesting small itches that got scratched by providing tools you just can't do without once you get to know them. We will present no less than 30 (thirty!) Open Source projects, providing code examples and small demos for each one of them. By no means is this intended as a comprehensive view on everything that's in the Long Tail: our expectation is to make attendees aware of the existence, and able to locate more, of a plethora of readily available Open Source software, while providing a few hints about what are, in our experience, some of the best hidden gems in the “small yet beautiful” landscape.*
