It's hard to think of individual episodes that stand out - the level of the podcast is pretty consistent and the hosts are just nice company. If you're looking for a starting episode, I would start from the first one.
From episode 1 to 300+ TechZing is a 10 year journey of friendship, tension, hacker talk and bootstrapping.
Of note, we were first to interview at least two founders who went on to build unicorns (Patrick Collison, Travis Kalanick) and many more who are now household names in the startup scene.
Security Now is pretty good. It's computers and networks from the perspective of security. Basically covers news events and how hackers find exploits, a lot of software engineering is covered.
Gotta go with https://corecursive.com/. There's a great range of topics, an engaging host, fascinating guest, and a vibrant slack community. It started with a focus on FP but has definitely broadened itself. 2 thumbs way up!
