  1. Our readingComputing is an onion, and the more layers of it you can peel back and understand, the better you can build for the constrained machines real people are using.

    Their wordsif you treat computing as this onion where you just keep peeling back the layers, there's always something interesting behind the scenes. And the more of those layers that you can peel back and understand, I think in some ways the better you can optimize for that world.
