I've done my learning in the Unix programming environment. It has forced me to learn the Unix toolset: grep, find, piping, little bash scripts for common tasks. Getting closer to the operating environment has helped make sense of the interactions among distinct components, ie how Python talks to Apache and the database.

I sort of trusted that lots of smart people have used this environment and that I'd learn a lot trying to emulate them. So far the only major disappointment has been the vi scripting tool, vimscript just feels like a dead end.

I do imagine that there is a lot of received wisdom embedded in something like Eclipse -- just browsing the menus would probably suggest all sorts of helpful tools and practices. I keep meaning to check it out, but just haven't made the time.
