Microservices are hard

other

At work, we are slowly breaking down the monolithic application into smaller manageable services. Some time ago we had a very interesting issue which proved that microservices are hard to implement. It’s especially true if you are not there yet but somewhere in the middle. When you need to introduce intermediate solutions which will enable you to work further on the migration to service oriented architecture.

asciidoc documentation

best-practices

One thing that a lot of people hate to do is writing documentation. Usually, it’s postponed until development is finished and once it’s done there is rarely time to do it properly. If you get past the struggle of writing it down there is always a problem of keeping it up to date. To avoid those pain points I’m going to explore what we can do with Asciidoctor to simplify this problem.

ArchUnit

java

In the past, I’ve implemented couple of tests that aimed to verify naming conventions or some other practices team agreed upon. And presented a way how to ensure they are followed. When I’ve been writing those I was not aware that there is a library that aims to test architecture conventions - ArchUnit in this post I’ll write a simple test case to check what’s possible out of the box.

The Kata

other

I’m learning python for some time now. I’ve made myself familiar with the syntax and then started looking into other ways to increase my knowledge about language and learn its quirks. I’ve found a very nice site that allows me to practice basics and strengthen different kind of muscles that I’m using in my day job - adventofcode.

From express and pug to HTML

javascript

While working on private stuff I’ve encountered a moment when I was in need to create a web-based user interface for the application I’ve been developing lately. In this post, I’m going to briefly describe why I’ve decided to use Node.js for generating HTML on the server side and how I’ve taken advantage of the javascript on the server side and in the browser.

Bisect the dragon

other

It all started on Friday, like many of the bad things that can happen in software ;) We’ve been working for some time and after being blocked with deployments for a long time (don’t ask, you don’t want to know ;)) we were finally able to deploy a new version. Our last release was about week ago. Do the deployment - seems like the easy thing to do. I’ve triggered deploy plan on Jenkins and it’s failed. Here is the story how I’ve fixed something that looked like hours of analysis in few minutes.

Kotlin first impressions

other

Recently while starting work on a project we’ve (team of two ;)) decided to try something new and use Kotlin. The project is far from ready and still under active development, but after writing some code in Kotlin I’ve got few observations I’d like to share.

Immutable dto in jackson

java

Immutability and functional programming are hot right now. But how to achieve immutability with objects deserialized from json? Luckily there is pretty old feature introduced in jackson 2.7.0 which uses constructor based object creation and uses @ConstructorProperties (introduced in java7).
