Boring Background I have always had in interest in making a local photo organization tool, that supports albums and tagging the way I want to do it. Maybe down the line allowing others to connect and use it too. So I started on one a few years ago, using what I knew best, Python REST … [Read more…]
Ok, so you’ve familiarized yourself with the rules. Good. This isn’t Fight Club, but they are important rules. You want to be a professional in all the projects on which you want to participate.

Reusables 0.8 has just been released, and it’s about time I give it a proper introduction.

Every coder will come across the same aggravating issue one day, finding a script or library you think you need, and it has zero instructions. Or the examples don’t work, or there is so much writing and so little substance you can’t hope to dig through it all to discover how it’s meant to be … [Read more…]
Logging vs Print The difference between logging and using print isn’t simply personal preference, rather choosing the proper tool per use case. Check out the Python docs when to use logging if you don’t believe me. If you are simply using Python to write scripts with clear paths and failure on error, it’s perfectly reasonable to not have … [Read more…]
