General

• I wish I had invented twitter: Ideas are worthless. Even the right idea at the right time is not necessarily enough.
• Interviews with software developers: People who created cool stuff. People who have achieved remarkable things. Programmers I look up to. Developers who have interesting stories to tell.

Software Development & Architecture

• Framework Design Principles: A mini series about framework and library design - or, more generally: Designing code for others.
• Simplicity: Simplify. Then simplify more. And: Don't let the code become complicated in the first place.
• Version Numbers: Why I don't like version numbers like "1.5.3" and what I use instead.

• Developers testing their own code Some considerations about testing code
• It's about courage: About refactoring, and courage as an agile value in general
• Working on a side project (just for fun): A mini series of posts about how I organize work on projects that I do just for fun.
