He created Meow Hash somewhat recently and open sourced that. It's not a huge project but it's very useful. A lot of his time goes toward education, his personal projects and contract programming. Not every programmer is dedicated to releasing their own open source or commercial software. I'd bet most programmers don't. Using this as a metric to claim that he has a bad coding approach is ridiculous and laughable. Especially using Handmade Hero as an example... It really reveals your ignorance.

Also, since you care so much, let's see what you've released, smart guy. Preferably code so that we can see how talented you are.
