Welcome

Welcome to MitchelSellers.com, this is my personal blog/commentary site and is in no way, shape or form affiliated with my employer.  On this site you will find a few key pieces of information.  In the Blogs section you will find technical articles focused around .NET Development, mostly C# content articles and with an emphasis on ASP.NET and DotNetNuke implementations.  If you are looking for technical assistance the Forums section is a great location to ask for specific help, I try to respond to all forum postings as quickly as possible.

For those looking to interact with me in a more direct route, such as Consulting or for a Speaking Engagement, these sections of the site will provide you the needed information to get in contact with me.  If you are looking for more information on my career and experience you may review an online copy of my Resume, or Contact me for more information.

Lastly for those attending any classes that I teach for the Business Information Systems department of Des Moines Area Community College (DMACC) you can view the Courses section to download any course specific documents.

Performance Testing Success Story: An Active Third-Party Vendor by Mitchel Sellers

I often talk about the importance of having well performing applications.  The reasons for my focus on performance are vast and range from the user experience, ability to handle load, Search Engine Optimization (SEO), and everything in between.  One of the most common issues that I will encounter with client sites when optimizing is that the root of their performance problem might reside with a third-party component that they have used.  Sometimes this was a component they selected, other times it was a component another consultant recommended, and even other times it was an item that was part of the framework that they were using and they did not have a choice.

This post is dedicated to a "happy story" with regards to performance optimization and experiences with third-party vendors.

Load Testing Your Application: Art or Science? by Mitchel Sellers
Earlier this year I blogged about this importing of understanding and knowing how your application will perform under load.  (See it here).  After receiving a lot of questions from individuals wanting to learn more about "how" they can load test their applications and the tools that I use when testing applications I thought it would be good to follow up with a post to shed a bit of light on the process.  

Understanding the Logistics of Moving Websites by Mitchel Sellers

Recently for a number of reasons I've been working with individuals that are taking a website and moving them from one hosting provider to another.  Sometimes these moves are taking the existing site as is, other times it is migrating to a "new site" at the same time.  However, after doing at least 10-12 of these in the past few months a few common points of "confusion" have come to light.  As such, due to popular request I'll lay out the basics of how to move a website from one hosting provider to another and discuss the component parts that are involved in such a move. Although a bit "off" from my normal development or performance topics this is still a very real thing for many people!

DNN Spam Registrations & You! by Mitchel Sellers
Recently there has been a lot of discussion in the community around DNN Spam registrations and methods and processes to prevent or fix the issues that are associated with them.  I've been debating on if/when I should actually write about this given that there is an Official DNN Software response on the issue, as well as many other community comments.  Well, tonight, while on vacation I had a server go down and guess what it was because of this very issue so I think its time to give my quick perspective and recommended action points for those of you that are running a DNN site.  These recommendations apply for ALL DNN versions!
