The more I work with deep inheritance hierarchies, the more I wonder if inheritance is actually a good idea. If you’re looking to avoid the trouble overusing inheritance can get you into, this article has some handy tips: Inheritance is evil. Stop using it.
We all know we have personal biases, but have you ever thought about your software design biases? I certainly didn’t until I read this article about Software Design Bias by Sandro Mancuso. If you’re having trouble with the design of a piece of software, it’s worth taking a look at Sandro’s handy list of biases and thinking about whether they way you prefer to design software is actually the best..

Persistence is enormously valuable, I even believe it’s more important than intelligence if you want to a programmer, but knowing when to quit is valuable too. That’s why I like I successfully chased my Big Life Dream, and I hated it by Rowen, so much. Their dream was to travel the world in a sailboat, yours might be to become a freelancer, to start your own business, to switch to game.. Read More
Learning Fluency, by Sara Simon is a really interesting article and you should definitely read it. It’s kind of hard to summarize, what I got from it was that there are a lot of parallels between learning natural languages and learning to program, one of which is that rote memorization is both really useful and really underrated. Variables and for loops are really boring for experienced programmers (which I’m suspicious.. Read More
You might have guessed from my extremely wordy blogposts that I like writing as well as programming :) Aside from having a personal interest in writing, I think there are some really useful parallels between writing and programming. Let’s talk about one of them: separating writing and editing. This is a pretty common piece of writing advice, I’ve seen it all over the internet. More specifically, what separating writing and..

I’ve been talking about code smells for a while, but code is far from the only thing that can go wrong. What about process smells? There are things in your development process that may not necessarily be wrong in every situation, but are a signal that something could be wrong. Some of these are more definitely stinky than code smells, but not all of them. As always, if you’re happy.. Read More
Why yes I do love mining the internets for blog post ideas :) This particular question is about learning a new codebase at work, but I think there’s plenty of stuff here that would carryover to learning the codebase of an opensource project you want to contribute to. When you want to learn a new codebase, the very first thing you need to do is get it to build on.. Read More
A while ago I mentioned that every Java project has to have a main method somewhere. I started thinking it would be interesting to dig into a larger project and show how even a whole servlet container starts with a main method, just like the smallest hello world program. So let’s poke at Tomcat! Why tomcat? Because it’s open source, I’ve used it before, and honestly it was the first thing.. Read More
Another blog post inspired by a question on The Workplace, specifically: does working at a bad company damage one’s career? Yes, but not the way the questioner seems to think. The bad company in this case is very disorganized, which I’m sad to say isn’t exactly unheard of. That company does sound like an especially bad example, but if you get a few developers together you’ll hear plenty of very similar.. Read More
Today’s code smell is temporary fields. Like with all code smells, sometimes these aren’t a problem at all. For example, it’s pretty normal to have a user object with a bunch of optional fields. Sometimes you have users who just start out with a username and a password and fill in their profiles later and sometimes you have fields for stuff like social media accounts that only some users will..
