This is my favorite photo of him because in combination with everything he's done and does it encapsulates why he's changed the world. I use linux every day and I'm grateful for it. Like a lot of geniuses, he's changed the world by being uncompromising. Unlike most geniuses, he backs up his shit with fearless openness about his feelings.
It's like he's open sourced the fact that he doesn't have time for everyone else's bullshit. I hope he has a happy birthday today.
