Canvas is fairly straight forward and only requires a basic knowledge of html and javascript. I decided a good start would be to try and make a...

Recently I was asked to make a bot for a local user group. The bot would simply report new events into the topic of an IRC channel. After the bot was created I decided to write an article about it and publish the code. The code and article  can be found here: http://www.dsmwebgeeks.com/2012/09/creating-an-irc-bot-stephen-dunn/ Basically the bot will...

At home and at work, I find that the things that I have to do over and over are the most painful. At home, it’s the dishes; at work, it reading data out of a file or doing Hibernate mappings. No matter what I do, I can’t seem to escape...

Beanoh.NET, pronounced 'beanˌō dot net, is a simple open source tool for verifying your Spring.NET context. Teams that leverage Beanoh spend less time focusing on configuring Spring.NET and more time adding business value.  Beanoh.NET is the .NET cousin of the Java version called Beanoh. You can install Beanoh.NET to your project...

In this post I am sharing different ways to create 'Custom Iterators' and how to control the behavior of that Iterator. Also part of this article focuses on how to apply different operations on a selected elements within a custom iterator. The way to do this is to implement a...

Forms in Django seem to be a relatively advanced topic if you want to do anything outside of models.  Case in point: I had to develop a multi-step form in django that would spit out a certain result.  There were only two forms that the user needed to fill out,...

Once you catch the automated testing itch you want to write test for everything. But should we use the same strategy for every piece of software? The conclusion that I've come to is no. While I'm completely committed to the practice of TDD and aggressive test coverage,...

I was fortunate to be able to attend the 2011 edition of No Fluff Just Stuff. One of my favorite presentations was by Matthew McCullough on Sonar. Hence, when the issue of code metrics was raised at a partner, Sonar seemed like the right tool to use. Our partner wanted to explore ways...

Parallel Programming is an emerging computer science field that studies the opportunity of splitting data into small chucks and process them on multiple processors simultaneously which provides a faster execution time. Parallel programming is useful in sorting, image processing, network processing and may other memory intensive tasks. For parallel program execution...
