Using Query Monitor for Your Database Performance Optimization
The topics of SQL and database performance optimization are important to a small percentage of WordPress sites. But when they matter, they matter a whole heck of a lot. It is in those situations that the WordPress plugin Query Monitor comes in. Maintained by John Blackbourn, Query Monitor is a great way to see what database queries were run on specific page of your site, and find out what the slow ones are.

WordPress Development for Beginners: “Does the User See It?”
Getting started with WordPress development can be disorienting. As I’ve written, software development (including WordPress development) is a lot like caving, and trying to do your first WordPress development project can be like waking up somewhere in the middle of a dark cave and trying to figure it out from there.
Using Git Subtree for WordPress Projects
Strap in folks, this is a nerdy one. If you’re not already a little aware of the role of Git in your life, there’s a good chance that this article isn’t going to work for you. While I will make sure I anchor our conversation about Git Subtree’s use in my WordPress development with a little context of what Git is, it’ll be minimal.
