A few from my list:

• Darknet Diaries - Interviews with interesting people around hacking and cybersecurity. This includes a lot of the actual criminals themselves and you get to hear their motivations and how they did what they did. Really neat for understanding the minds of folks who do bad things.
• FiveThirtyEight Politics - This one is good for staying abreast of US politics, polling. While the political bias of the hosts is pretty obvious, this is less punditry and more about the numbers.
• Risky Business with Nate Silver Maria Konnikova - A neat podcast covering risk, poker and politics. Just a good listen for thinking about risk and probabilities in life.
• The Lawfare Podcast - Lawyers talking about the law, and how it shapes and is shaped by whats in the news. Great for getting a legalistic view of the world.
