John Carmack Quotes

Focused, hard work is the real key to success. Keep your eyes on the goal, and just keep taking the next step towards completing it. If you aren't sure which way to do something, do it both ways and see which works better.

I do hear sometimes from programmers who are kind of sad that they don't have the opportunity to write game engines from scratch like I did and have it matter or make an impact...here's where some perspective really helps - I can remember when I was a teenager, I thought I had missed the Golden Age of 8-bit gaming, that I was never going to be Richard Garriott...time went by, and I got to make my own marks in things after that. And, in that time, I also see so many opportunities that have come by. The 90s PC wave was great - I was happy to be there, and I'm glad I took a swing and knocked one out of the park with that. But since then, we've seen mobile games, and web games, and free-to-play games, the Steam revolution...and now . And all of these are amazing! So, yeah, the opportunities that I had aren't there for people today - but there are new and better ones. And personally, I'm more excited about these than anything that's come before. So, thank you very much for this honor, but I'm just getting started.

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.

The Xbox 360 is the first console that I've ever worked with that actually has development tools that are better for games than what we've had on PC.

Programming in the abstract sense is what I really enjoy. I enjoy lots of different areas of it... I'm taking a great deal of enjoyment writing device drivers for Linux. I could also be having a good time writing a database manager or something because there are always interesting problems.

I’m going to turn on every damn light in protest of Earth Hour. Lighting the darkness is fundamental to humanity's climb.

Everything is an interpolation problem if you have enough data

I was sort of an amoral little jerk when I was young. I was arrogant about being smarter than other people, but unhappy that I wasn't able to spend all my time doing what I wanted. I spent a year in a juvenile home for a first offense after an evaluation by a psychologist went very badly.

Note to self: Pasty-skinned programmers ought not stand in the Mojave desert for multiple hours.

It is hard for less experienced developers to appreciate how rarely architecting for future requirements / applications turns out net-positive.

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.

The biggest problem is that Java is really slow. On a pure cpu / memory / display / communications level, most modern cell phones should be considerably better gaming platforms than a Game Boy Advanced. With Java, on most phones you are left with about the CPU power of an original 4.77 mhz IBM PC, and lousy control over everything.

Because of the nature of Moore's law, anything that an extremely clever graphics programmer can do at one point can be replicated by a merely competent programmer some number of years later.

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.

Nvidia's OpenGL drivers are my 'gold standard', and it has been quite a while since I have had to report a problem to them, and even their brand new extensions work as documented the first time I try them. When I have a problem on an Nvidia, I assume that it is my fault. With anyone else's drivers, I assume it is their fault.
