Twitter Integration Plugin for JetBrains IDEs
I have implemented a small IntelliJ plugin to post code to Twitter. I often see tweets with code, so I thought why not make a better way to tweet. When you have the plugin installed, you can right-click on a selected piece of code, press “Tweet” and your IDE will redirect you to the Tweet creation window in your browser with the selected text.continue...
Using 'any' Matchers in Unit Tests Is a Code Smell
If you’ve worked with JUnit and Mockito, you must be familiar with matchers. They provide a way to verify parameters during method invocation. Among many of those, there is a group that allows matching any object as a condition. Their names all start with the word ‘any’:continue...
anyCollection(), etc. If in your project, you find many of such calls there is a high chance that something is wrong with your code. Let me explain why.

Why You Need to Implement Your Own IntelliJ IDEA Plugin
IntelliJ IDEA is a powerful tool that aims at increasing productivity. It speeds up the development process and optimizes most of the standard use cases such as code formatting, code generation, navigation, etc. However, the utility of IntelliJ IDEA is not limited to these processes. For instance, I set up my IDE to generate tests prefixed with the word ‘should’. My IDE also automatically adds annotations to test classes depending on their names. But what could make an IDE even more useful is implementing an own plugin that will optimize processes that cannot be customized via standard tools. What exactly could be achieved thereby? And how complex is it? This is what I’ll try to address in this blog.continue...
Why Event Sourcing Is Not a Choice for Your Next Project
Event-driven architecture has become extremely popular nowadays. It is easy to start and it can easily be integrated with popular Java frameworks like Spring. I have been working on event sourcing for the past six months. In this period, I have collected some thoughts on the subject of event-driven architecture. Despite all its features, I believe that such architecture should be applied very carefully in terms of understanding its consequences.continue...
Implementing do-while Loop in Scala
I have recently completed a Scala course on Coursera. Now that doesn’t turn me into a Scala programmer; however, the knowledge I acquired certainly has been very helpful with my everyday projects, especially when it comes to applying that knowledge to Java stream API. One of the tasks proposed by Martin Odersky was to implement a do-while loop using only Scala built-in features. This statement made a great impression on me. It’s proof of the power of the language and its features. In this blog post, I want to share the implementation of the do-while loop in Scala with you.continue...
Shipping Docker with a Java Application
Docker is not a new technology anymore. In the meanwhile, it has become an everyday tool for many developers. However, there are still a lot of people out there who haven’t tried Docker. In this article, I’m going to show you how to ship a standalone Java application in a Docker container.continue...
