Refactoring For Interfaces: An Adventure From The Trenches

Refactoring: Some Background If you're a seasoned programmer you know all about refactoring. If you're relatively new to programming, you probably have heard of refactoring but don't have that much experience actually doing it. After all, it's easier to just rewrite things from scratch instead of trying to make a huge design change part way through, right? In any mature software project, it's often the case where you'll get to a point where your code base in its current state cannot properly sustain large changes going forward. It's not really anyone's fault--it's totally natural. It's impossible to plan absolutely everything that comes up, so it's probable that at some point at least part of your software project will face refactoring. In my real life example, I was tasked with refactoring a software project that has a single owner. I'm close…

Leadership: What Does It Mean? – Weekly Article Dump

Leadership Everyone has their own variation of what leadership means. For me, leadership means empowering others to accomplish their goals and providing assistance when they need it. There were a few articles that came up on LinkedIn this week that I wanted to share with everyone and discuss how they fit into my perspective on leadership. Articles Does Your Team Work With You Or For You?: Kwame Manu-Antwi opens up the article in an interesting fashion. When I read the title of the article, I figured this was going to be the typical leadership vs management debate. However, Kwame goes into describing a scenario where he had a humbling experience from one of his team that made some sacrifices for him. This was truly an example of working for him. The entire second half of the article shares a bunch of…

IronPython: A Quick WinForms Introduction

Background A few months ago I wrote up an article on using PyTools, Visual Studio, and Python all together. I received some much appreciated positive feedback for it, but really for me it was about exploring. I had dabbled with Python a few years back and hadn't really touched it much since. I spend the bulk of my programming time in Visual Studio, so it was a great opportunity to try and bridge that gap. I had an individual contact me via the Dev Leader Facebook group that had come across my original article. However, he wanted a little bit more out of it. Since I had my initial exploring out of the way, I figured it was probably worth trying to come up with a semi-useful example. I could get two birds with one stone here--Help out at least…

Be a Better Programmer – Weekly Article Dump

Be a Better Programmer It's a new year and that means it's all about resolutions, right? Well, I'm not a huge fan of keeping around a resolution that needs to wait for a new year, but I am a fan of reflecting on your goals and your skills. If you're a programmer like me, then maybe this will be a great starting point. In my weekly article dumps I usually would just provide a couple of comments on a link like this, but I felt I should dive in a little bit more. You can find the original article by Amy Jollymore over here. Please have a look! I shared it with the whole dev team at Magnet Forensics because I felt there was a little bit of something for everyone. Number one on this list, and perhaps the one…

Movember Wrap-up – Weekly Article Dump

Movember Wrap-up At the start of December, it's time for a lot of us to shave off our glorious Movember badges from our upper lips. This year, MoMagnets did an absolutely amazing job raising money for Movember. At the time of writing, we're sitting at just under $2400! An incredible effort by Magnet Forensics and all of those that helped with their generous contributions. My 'stache didn't quite get to where I wanted to this year. It was close, but it was another connector-less Movember for me. I was almost able to get some twisting done for some not-so-legitimate connectors. Oh well... Here's what I ended up rocking for most of the month: Matt Chang definitely took the lead for raising the most of all the MoMagnets members at over $700! Mica Sadler is sitting in second at just under…

Code Smells – Issue Number 3

Code Smells Welcome to the third edition of Code Smells! Periodically I’ll be posting about how to detect code smells and what they mean in terms of the big picture of your code. The previous installment can be found right here. What’s a code smell? Wikipedia says it perfectly: In computer programming, code smell is any symptom in the source code of a program that possibly indicates a deeper problem. Code smells are usually not bugs—they are not technically incorrect and don’t currently prevent the program from functioning. Instead, they indicate weaknesses in design that may be slowing down development or increasing the risk of bugs or failures in the future. These code smells are often based on my own opinion and experience with programming. If you disagree with what I'm saying in my post, please don't hesitate to post a comment. I'd love to clarify anything I may have worded poorly and discuss…

Performance Reviews – Weekly Article Dump

Performance Reviews It's almost the end of the year, and performance reviews for many companies are just around the corner. This will be the first time for me sitting on the other side of a performance review. I'm excited, and to be honest, a little nervous about how it will all play out. I know our HR manager has done an excellent job putting together our initial take on performance reviews, but it's still going to be up to me to ensure that all aspects of a performance review are communicated properly to my team. It's definitely going to be an interesting time of year! I've started doing a little bit of reading on performance reviews. From what I can tell, the general consensus is that most performance review systems are flawed and nobody knows the perfect way to do…

Lambdas: An Example in Refactoring Code

Background: Lambdas and Why This Example is Important Based on your experience in C# or other programming languages, you may or may not be familiar with what a lambda is. If the word "Lambda" is new and scary to you, don't worry. Hopefully after reading this you'll have a better idea of how you can use them. My definition of a lambda expression is a function that you can define in local scope to pass as an argument provided it meets the delegate signature. It's probably pretty obvious to you that you can pass in object references and value types into all kinds of functions... But what about passing in a whole function as an argument? And what if you just want to declare a simple anonymous method right when you want to provide it to a function? Lambdas. So…

Fragments: Creating a Tabbed Android User Interface

Fragments: A Little Background Update: The actual application is available on the Google Play store. Once upon a time, Android developers used only two things called activities and views in order to create their user interfaces. If you're like me and you come from a desktop programming environment, an Activity is sort of like a form or a window. Except it's more like a controller for one of these classes. With that analogy in place, a view is then similar to a control. It's the visual part you're interacting with as a user. I remember the learning curve being pretty steep for me being so stuck in my desktop (C# and WPF) development, but once I came up with these analogies on my own, it seemed pretty obvious. So to make an Android application, one would simply put some views together…
