Game Dev Design & Patterns for a Board Game

As a fan of the board games, I started to adapt the Eldritch Horror to make it available for PC and Android. In my blog, I will shortly describe the architecture, design patterns and of course, the obstacles I run into while developing this game. It was implemented in Java using LibGDX framework. It is far from being finished as it contains a lot of components. But the core of the game is done. So, let me share with you what you should (not) do when you decided on going on the same journey...

Internet of Things (...in the Cloud, too)

In this blog, I would like to introduce to you one of my latest hobbies – Internet of Things (IoT). We will go through a short intro and then jump directly into creating some cool "things" connected to the internet. This tutorial will help you create two simple (yet very useful) creations that could make your life easier. And of course, as I’m a Cloud Specialist, we will try to "touch" the Cloud in the second guide :). Dig in.

Why exploratory testing does not have to be a dirty phrase

In managerial circles, the activity covered by the term 'exploratory testing' has gathered something of a bad reputation. From the perspective of the uninitiated, it might seem as just random clicking and typing until something goes wrong and we can create a bug report. However, this is not the case at all.

Angular and Spring security integration (PART 1)

In my previous blog, I focused on showing the benefits and basics of Angular 2 in combination with a PrimeNG UI component library. However, majority of applications are not formed only by the front-end part (Angular 2 in this case), but also have their complex business logic, data storage and more. In my case, I decided to show the back-end using Spring framework; specifically, SpringBoot as a convention over the configuration support.

How to code rules in Drools

I work for Davinci on the Skydoo project where the business rules are implemented in Groovy, which is an object oriented, dynamic and scripting Java platform language. I got a task to write rules in DSL (Domain specific language) MVEL for a new project. I went through many pages about the MVEL language and most of them were about the rules platform named Drools, so I dived in.

Easy way to add Drag&Drop to your GWT based applications

I am programming a mid-office application with the GWT 2.5.0 front end.

But GWT 2.5.0. does not support the drag & drop function.
