The situation is so much better for programmers today - a cheap used P — John D. Carmack

"A large fraction of the flaws in software development are due to programmers not fully understanding all the possible states their code may execute in."

"Personally, I’ve always been of the sleek and minimalist design school: make sure the core play is consistent and strong, then let that idea play out against different environments and challenges, this tends toward focusing on bio-mechanical twitch responses, audio-visual awe, and leaning more toward general strategy and tactics development over specific puzzle solving."

"Its a good thing Doom 3 is selling very well..."

"Sharing the code just seems like The Right Thing to Do, it costs us rather little, but it benefits a lot of people in sometimes very significant ways. There are many university research projects, proof of concept publisher demos, and new platform test beds that have leveraged the code. Free software that people value adds wealth to the world."

"I think a lot of people may take some heart from this: a lot of the math, the heavy math in projective geometry, [...] took me a long time. There were many many years, a decade, when I was considered this graphics guru genius, when I really couldnt do from scratch [...] the mathematics that underpins a lot of that. But slowly, eventually, with a couple decades of experience, most of it did eventually sink in on me."

"But realistically, we don’t have that many problems at QuakeCon. If it was a football convention or something, there would probably be a lot more incidents."
