Lex Fridman Podcast #309

• Lex Fridman: What's the best programming language?
  John Carmack: Everything has all the caveats about it. So what I use—so nowadays, I do program a reasonable amount of Python for AI/ML sorts of work. I'm not a native Python programmer, it's something I came to very late in my career. I understand what it's good for.
  Lex Fridman: But you don't dream in Python.
  John Carmack: I do not. And it has some of those things where there's some amazing stats when you, say, if you make a loop, you know, a triply nested loop, and start doing operations in Python, you can be thousands to potentially a million times slower than a proper GPU tensor operation. And these are staggering numbers. You know, you can be as much slower as we've almost gotten faster in our pace of progress, and all this other miraculous stuff.
  Lex Fridman: So your intuitions about inefficiencies within the Python—
  John Carmack: It keeps hitting me upside the face, where it's gotten to the point now I understand it's like: okay, you just can't do a loop if you care about performance in Python. You have to figure out how you can reformat this into some big vector operation or something that's going to be done completely within a C++ library.

Interesting excerpt from an interesting interview, but the quote could use some shortening. Proposed shortening:

It took me a while to figure out that the zen of mac development is 'be at peace while rebooting'. I rebooted my mac system more times the first weekend than I have rebooted all the WinNT systems I have ever owned.... there is just no excuse for an operating system in this day and age to act like it doesn't have access to memory protection."

When I played through them, I was almost morally indignant that someone would make these really awful games on this platform. Because I was looking at this and thinking, "There's more power in this handset than all of the early [personal-computer] games that we made back in the Commander Keen days. Why do these games suck so bad?"

• "Using your time effectively is very important, and there is often a non-linear relationship between the amount of time you can stay focused and the amount that you can learn or accomplish. It is often possible to get more done in a highly focused 12 hour stretch than in a normal 40 hour work week that is interspersed with email, chat, and other distractions. Someone that can be completely obsessive about something does have an advantage, but the same questions about focus apply for any amount of time you choose to devote to an undertaking. Most people work at only a fraction of their potential." John Carmack
