Quotes:
- “Software development and software code, in particular, are very abstract. There’s no way I can really take a software system and pull it out and turn it around and inspect it for flaws.” — Adam [6:34]
- “What I’m most interested in is trends; so are we moving in the right direction or the wrong direction?” — Adam [15:14]
- “My experience, from working with all of these companies, is that pull requests and code reviews, in general, are extremely valuable… but they also tend to become a bottleneck in practice.” — Adam [16:10]
- “A surprise is simply one of the most expensive things you can put into a software architecture.” — Adam [30:15]
- “While these mechanics are simple, information is only good when acted upon.” — Adam [31:20]
