My favourite three are:

• Darknet Diaries
  I imagine this one is familar to most podcast fans that might stumble upon this post. The host is a fantastic interviewer, storyteller and producer. He interviews incredibly interesting people and shares their stories about all things dark net: hacking, social engineering, dark web, darknet markets and more.

• Self-Hosted
  A podcast about all things self-hosted. The two hosts are passionate self-hosters who like to discuss open-source solutions, self-hostable products and technical setups. They are highly experienced and have a ton of useful information to share. They have great guests on the show, and have built a brilliant community around the topic.

• Coding Blocks
  A general software engineering podcast. I find some episodes a bit hit or miss, but the three hosts are hilarious, informative and very entertaining. You can tell they are three very close friends who absolutely vibe off of one another. They cover all sorts of topics including programming languages, development tools, books, conferences, frameworks, companies and more.
