The ultimate dev skill is Integration Testing feat. Internet of Bugs [Podcast #209]

Today Quincy Larson interviews Carl Brown, who runs the Internet of Bugs YouTube channel and has worked as a dev at Amazon, IBM, Sun Microsystems, and startups for over 37 years. We talk about: - The hype versus the utility in LLMs and agent code generation tools - Why you might want to target developer jobs at smaller companies, and how these differ from "big tech" - How everyone will face agism eventually. Carl argues that a consulting career is a great escape hatch. Support for this podcast comes from the 10,113 kind folks who donate to our charity each month.
