Like all developers, I listen to development podcasts and read blogs. Those are my favorites:

Podcasts

• This developers life is not just an ordinary podcast, but a professional made radio play about "developers and their lives".
• ZukunftsArchitekten-Podcast, a very good german podcast about the art of systems engineering.

Blogs

• Sven Peters is an "evangelist for Attlassian", the guys who build Jira and Confluence. In his German (!) blog he focusses on software development processes.
• Jens Schauder writes (in German!) about all topics in software development and has a soft spot for Scala.
• Notch, also known as Markus Persson, is the inventor of Minecraft. His blog is not an actual development blog but it gives insights into the process of growing a software company.
• karrierebibel, also a German blog, is a collection of articles about business, IT and entrepreneurship.
