Ask HN: I'd like to learn French without enrolling in classes

Some background: I'm a programmer with two jobs(day job and consulting), so my time is severely limited. I already know several programming languages and have no problem picking more up in a short time(picking up as in understand and write the syntax. "Learning" a language actually takes a long time). English is a second language to me(Arabic is the native one).

Now I'd like learn French to be able to converse in. Any helpful pointers?
