Since the release of Java 8, I almost immediately started using the Stream API, because I liked the functional approach of data processing. I wanted to use it everywhere, so I began developing my own library, which brings a similar approach to earlier versions of Java, specially for Android. I was also interested in the stream internals. Over time, I've accumulated enough experience, and now I'm eager to share it.

In this article, along with a description of streams, I provide visual demonstrations of how operators work, as well as examples and self-checking tasks. It also covers new features related to streams in Java 9+.

In this section, we will create a CLI application in Rust that collects all the necessary data to display photos on the map: coordinates, some camera information, a thumbnail, and will also generate the map.

If there are a lot of photos, displaying them all at once on the map is not the right choice for UX and performance. So let's group the photos and display their count.

I've always found it tedious and difficult to display stuff on maps. To understand the API, you need examples that aren't always accessible because they require a token to display and interact with the map. The token has to be obtained and hidden from other people's eyes.

But then I thought, why do I need proprietary Google Maps when there is OpenStreetMaps? I searched for APIs, came across OpenLayers, opened examples and was surprised by their number and simplicity.

In this series of articles, we will explore OpenLayers, display photo thumbnails on a map, add clustering, and finally create a Rust application that collects geodata and thumbnails from photos and generates a map.

Every time we add a new if or for to code, we have to increase the indent of the condition body or loop. The more nested loops and conditions, the broader your code becomes, and the more difficult it becomes to read. In this short article, I’ll show a few techniques by which you can avoid increasing indentation. Your code will be clearer, and you’ll never see horizontal scrolling.
