As I wrote in the previous post, one of my New Year’s resolution for 2011 is to write at least one blog post per week. Unfortunately, it’s not something I can simply mark as “done” until the end of the year. But another item on that list was to publish my first open source project, and that’s what I decided to do today. One of the projects I’m working on (a WordPress site) needed a sidebar widget that looked like a calendar, with each cell being a month showing how many posts were published on that month. Since I couldn’t find a plugin with that functionality, I decided to write my own. After I finished writing the plugin for the project, I realized that it was fairly simple to make it more generic and publish as a WP plugin.
