Following up from the previous article about implementing the fog of war in leaflet, I want to be able to load a GPX file and display it in the map.

Following up from the previous article about implementing the fog of war in leaflet, I want to add some markers to the map and to create a polygon that joins them. Let’s see how I manage to do that.

When I was playing age of empires the map was all in black color at the beginning. As long as you explore the map, the black color is removed discovering what it was hidden behind. I wanted to implement something similar to show all the trails, routes, paths, roads, streets, etc that I have discovered. I’ll describe the callenges I have found in a series of articles.

I was implementing a searching algorithm and I had to search for two things. In this article I describe how I implemented combining two Java optionals.

I’m doing a side project using golang, and I have a use case where I’d use an abstract class in Java. Unfortunately, in golang the concept of classes does not exist. In this article I describe how can I implement the behaviour I want without abstract class.
