About this podcast
Deep-dive discussions with the smartest developers we know, explaining what they're working on, how they're trying to move the industry forward, and what we can learn from them.
You might find the solution to your next architectural headache, pick up a new programming language, or just hear some good war stories from the frontline of technology.
Join your host Kris Jenkins as we try to figure out what tomorrow's computing will look like the best way we know how - by listening directly to the developers' voices.
