One of the things I like about MySQL is that it allows you to change some of its global state as it’s running. This article will provide a quick overview of how to view the current variables and how to make changes.
Please note: All examples in this article were written using MySQL 5.5 and done in a development environment. Please do not try this on a production environment unless you are sure of the ramifications.Read More
In the next couple weeks our family will be welcoming an addition to our family. We’ve actually been spending the last several months working like crazy around the house trying to get everything in order. I’m anticipating that the frequency of my updates to this site and the length of the articles will slide a little but I’m dedicated to continue to generate helpful items even if they’re not long form. Hopefully in the fall I’ll be able to get back on a regular schedule.
Also as part of my trying random stuff with social media and seeing what sticks, I’m going to start posting little images on our Twitter and Facebook Pages. You can follow us or follow #TPTTeachMeSomething.

As a developer, I don’t find it natural for me to do just one thing to my code base between commits. I end up cleaning up a couple things as I’m working on a new feature or bug ticket or even lump together two tickets that touch the same module. To this end, some of my commits ended up looking like this:
Eventually, I (or even worse someone else) would try to figure out what happened in that commit and have no idea because of the shitty commit message. That all changed the day I learned aboutRead More

I’m fiddling with the Symfony Demo Application for an article I’m researching and I wanted to use it with MySQL instead of SQLite (which it defaults to). In order to make this change I had to do the following:
1. Change .env to Use MySQL
Open your .env file and find the following line:
And change it to the following:
2. Reset the Database
At some point, it’s going to be necessary for you perform some scheduled tasks in your application. Here are three options for how to do this in PHP.Read More

The other day one of my old clients contacted me because an application I had developed for them (5+ years ago) was slow. My first step was to download New Relic to their server but I found their configuration wasn’t supported anymore. I had to start building a footer that displayed page rendering information (makes me even happier to use New Relic in my other projects) and what I found shocked me.
They have a list of vendors which are then picked in various select elements through the site. When we originally created the system they had ~100 vendors. In the past five years they’ve entered 1,500+ vendors. Some pages had multiple (in one case 10+) vendor selects which caused the page to be 35 MB of just option elements and because everything was written using classes it caused 15,000+ classes to be instantiated and then used. I do love PHPs speed though, on my local machine this still didn’t take more than a second to generate and it was really only a problem when using the page through the Internet.
As programmers it’s impossible to tell how our systems will be used. When we originally created this system we used the information they had given us to create the best system we could for their budget. Even now I wouldn’t have tested their system with as many vendors as they’ve managed to enter but it’s important for us to build systems that scale.
The last time I rearranged my desk and decided I would try using one of my monitors vertically instead of horizontally. I’ve spent a year using it this way I thought I would talk about what I’ve liked and what I’ve disliked.
