Welcome to AC Brown’s IT World!

My name is Adam Brown. I’m an IT Guy. I’ve worked most of my life fixing computers and tinkering with technology. I’ve spent thousands of hours studying and learning, and I’ve gotten to the point where I want to share what I’ve learned with others in a way that will hopefully save time digging through useless details.

My goal with this blog is to build a center of knowledge for IT professionals around the world. Over the past few years I’ve built a few good posts that have helped a lot of people out, but I feel like there’s a huge gap in the Internet’s ability to teach people how to work well and effectively in IT.

Most IT Blogs focus on the “how to” part of IT work (The Practice), with very little information about the “why” (the Theory). The problem with this approach is that it results in a lot of people just following instructions without thinking about what they’re doing or why the solution they have is recommended. I’ve had to fix a whole load of problems caused by people who just did stuff because someone told them to, and I’m sure there are loads of IT environments out there suffering from the same issues.

In this blog, I’m striving to not only explain *how* to do things, but *why* it should be done that way. This is much more difficult to do and will require additional reading from anyone here, so I am separating all of my posts into Theory and Practice, so you can get the answer you want quickly, but also have an easy way to learn more about what you’re working with when you have time to do so. This will likely be a massive undertaking for me, and I appreciate everyone’s patience while I build things up.

Below is a Table of Contents of sorts, outlining the starting point for some of my posts.
