lol not really, but I do find myself using a Java hashmaps and not knowing how hashing works, using a regex that was copied and pasted from google without understanding what it does, programming in java and not knowing how the GC algorithms work, or working with threads and not knowing the basics of OS schedulers, programming and not being proficient with bitwsie opperations... and the list goes on, at least that is my interpretation of a cargo cult "java" programmer.
