I have a lot of friends that use Vi, one of them today was around and catched me working on a C program inside Emacs. He got impressed by one of the Emacs modes called Flymake, it does on-the-fly spell checking and I was using it with the gcc compiler. I’ve recorded a video to show how this mode works.
