This talk dives head-long into the controversy and anti-typing rhetoric, looking at things through the lens of a language designer and enthusiastic type theorist. We will explore the…

You’ll never have to worry about parts of your view remaining out of sync with updates made by other parts. Because all views reflect the current state of…

ETE 2012 – Douglas Crockford – JavaScript, Programming Style, and Your Brain

From the abstract: Computer programs are the most complicated things that humans make. They must be perfect, which is hard for us because we are not perfect. Programming is thought to be a “head” activity, but there is a lot of “gut” involved. Indeed, it may be the gut that gives us the insight necessary for solving hard problems.
