One of my coworkers sent this Kotaku article by game developer Shawn McGrath to our internal code readers mailing list. It’s a review of the Doom III source code, describing the beautiful coding style of Id Software founder John Carmack, one of the programmers who I most respect.
It’s a thoughtful article about thoughtfully written code, and really shows the value of reading code for the practicing programmer.
One of my favorite things about John Carmack is that he has always been more of a craftsman than a theoretician when it comes to developing software. To get an idea of what I mean, take a look at his blog post on functional programming in C++, which he linked to in his comment on the Kotaku article. Carmack’s post is a far better introduction to the benefits of functional programming than the one I linked to the other day.
