MP 142: Advice from a climbing guide that's quite relevant to programming. Note: The debugging series will continue shortly. I'm busy getting ready for PyCon, and haven't had time to finish the next post in that series yet. Since moving to North Carolina last
MP 140: How can we take a systematic approach to a "simple" bug? Note: This post is part of an ongoing series about debugging in Python. The posts in this series will only be available to paid subscribers for the first 6 weeks. After that they will be
MP 139: A systematic, inquisitive approach makes debugging simple issues easier, and complex bugs possible. Note: This post is part of an ongoing series about debugging in Python. The posts in this series will only be available to paid subscribers for the first 6 weeks. After that they will be

MP 133: Naming things is hard, but renaming things can be even harder. I've been steadily working through the remaining issues that should be closed before the 1.0 release of django-simple-deploy. One of the last things to address involves reconsidering a name that's used throughout
MP 132: It's a simple built-in function, but using it isn't as straightforward as it might seem. A task that's come up repeatedly in my programming work involves looking through a collection of values, and taking an action if a specific item appears anywhere
MP 131: It seems like Git is always more capable than I realized. I've been using Git for almost 20 years now, and I still discover new ways to use it more effectively. I really appreciate a tool that has more to offer every time I use a
MP 130: How do you make a reasonably secure access code for an electronic door lock? We recently moved into a new house, and one of the first tasks after moving in is to change the locks. Rather than just rekey the existing locks, we decided to install electronic locks.
