Here is a tip for all geocachers out there that like me tend to get stuck when trying to solve mystery-caches. I quite often understand the mystery and how to solve it but I don’t know where to find the tools to complete the task. I have now found a tool to create my own tools in the class “An Introduction to Interactive Programming in Python” hosted by Coursera.org. It’s not any fancy programming but it’s enough to create your own decrypters, bearing calculators and small tools like those. Go and check it out, it’s almost halfway through the course but all the material is there for anyone to take for free.
