I've been doing this almost 40 years and have never had to pay for either.

Now, if you don't find gcc and neither of vi (and later vim) or emacs usable, well, let's not go there.

And the tools, they just keep getting better. Now I have both clang and gcc, and so many wayy-cool vim plugins to choose from.

I still pay for good hardware, but thanks to Linus and his ilk, I barely need to do that anymore.
