Little Happy Accidents discusses debugging techniques such as printing, using a debugger, logging, and writing tests to prevent and fix bugs. It notes that bugs will inevitably happen and these skills help spot, fix, and patch bugs via pull requests. Different languages have different printing syntax like print() in Python 3.0+ and puts in Ruby. Logging provides access to a history of problems while printing only works when actively debugging. Writing tests both during and after development can prevent bugs from reoccurring. Speaking aloud to explain an issue, as with a rubber duck, can also help troubleshoot problems.
