Why do we feel so uncomfortable with the idea of small functions that have names? What is it about that that frightens us? I’ll tell you what it is. It’s the fact that long functions are familiar to us in a very deep way. Take a long function and turn it on its side, and

I wanted to quit writing software for good. Nevertheless, I coded. And I still do. I’ve been a software developer for 3 years then. And I totally didn’t feel like getting up and going to work. I struggled with my tasks and worked much slower than I used to. I tried to look for another
You can probably come up with a bunch of answers: the computer, the client, the cloud, the company… But first and foremost you write code for other developers. And for your future self.

Last Sunday I’ve talked to a friend. She just recently picked up Java. We’re about to start a learning experiment: she is going to learn how to write code in Java, I’m going to help. Work out a plan and set up exercises. I decided to blog about what we’re doing here. The “learning” posts will be visible
This year I’ve explored Java world again @DevoxxPL in Cracow. And whereas last year was full of the microservices and functional programming hype, this year was more steady. Microservices are still a dominant architectural trend. Aside from different aspects of Java (like an overview of Java 9, JVM Mechanics, JEE 8, Concurrency concepts, performance or
