Episode 524: Data Munging Play-by-Play Part 2 with Avdi Grimm
In the last episode, I showed you a play-by-play of a real coding session in which I needed to filter a large recipe database into a smaller list of recipe names. Today you’re going to see the conclusion of that session. As before, the coding is un-rehearsed. The only changes I’ve made are to speed it up by a factor of three, and cut out some distractions. I’ll once again be accompanying the video with some after-action commentary, to explain my thinking as I tackled the problem.
