Software Unscripted https://twitter.com/sw_unscripted is good. I don't know whether it's well known or not. Possibly a hidden gem.

Already mentioned, but Signals & Threads https://signalsandthreads.com is a very notable one. Probably the best episode hit-rate of any development-related podcast I've listened to.

Core Intuition https://coreint.org Apple-platform focused. Hosts have endearing personalities.

The Changelog https://changelog.com/podcast Good interviewers and wide-ranging episode topics (some get deleted - I won't subject myself to Kubernetes-related blather!)
