I was already a pretty proficient programmer before I got to college. I coded by writing a couple lines, building, fixing any errors, and then writing a few more lines, etc. Seemed very natural to me.

I remember my CS prof being taken aback by my approach. She was telling the class to write as much code as possible before compiling because she still thought of compiling as slow.

Now all our IDEs recheck everything with every single character change.

Just something I think about sometimes.
