Doing some development work in a language that I'm by far not used to, and it's frustrating: it takes me more than twice as long to do things because the way I want to do them isn't what the compiler wants. It's all object-oriented, but that's pretty much where the similarity ends.
Simple things, like wanting to XOR two bytes... three hours spent on trying to figure out a way to do it before giving up and moving on to something else. Or simply promoting a byte to an integer or vice-versa. Incompatible types.
I figure I'm gonna have to drop some extra time on this piece to get it operational by Monday. We'll see how this week goes.
