Visual accessibility is the foundation of a website that can serve everyone. From readable text to sufficient contrast to clear navigation, every detail matters. Clearly defined principles help maintain consistency and ensure a fair user experience.

Every website should be designed to be accessible to everyone, from experienced users to people using assistive technologies. To ensure this consistently and without compromise, we need clearly defined rules.

Do you have an idea that you want to turn into a functional digital product and you want everything to run smoothly? One of the key steps that determines whether a project will go according to plan or start falling apart at the ground level is a good estimation - an estimate of the time, cost and capacity required.

GR8 Days - an event that we at GoodRequest look forward to every year. Days when we close our laptops and swap meetings for personal conversations. GR8 Days are a mirror of who we are as a team.

The element of gamification is an interesting way to increase the appeal of an app to the user. Whether it's for a passionate collector of rewards, a competitive person, bored person, or for someone who wants to earn a discount by playing. There are many paths of gamification. Just creating an avatar or tracking progress is enough for many users to achieve the goals the app encourages them to. However, in this context, we will discuss exclusively about games.

In this article, we will take a look at some of the technologies that we in Goodrequest use on a daily basis to make Android development more efficient, effective, and at least a little more enjoyable.

A* Search Algorithm .png

A* is one of the very important algorithms for understanding how you can improve graph traversal (finding the most optimal path). We will improve Dijkstra's algorithm, which we showed last time. It searched for the shortest path through the graph without taking into account the position of the target. So it made a circle around the starting point.

One of the very common requests across various Android applications is video playback. The Exoplayer library is one of the most popular libraries designed to accomplish this task. In this article, we will look at how to use it and implement it in Jetpack Compose.

Today we will move into the area of so-called search algorithms. With all search algorithms, we will inevitably work with graphs. All search algorithms are looking for the best/shortest path through the graph. We will not dive in deeply into the theory. We will try to show everything in pictures. Let's call this form of learning learning by leafing through the leperole 🙂

When I was starting with development on Android, I was totally lost. If not for help from senior android developers in my first workplace, it would take some more time to wrap my head around. Now is my time, to share some wisdom.

All the optimization algorithms that we have tried so far modified one randomly generated solution, modified it and, under certain conditions, accepted it for the next "round". The algorithm that await us now work on a slightly different principle. Instead of one solution, we will generate several random solutions and they will influence each other.

Simulated Annealing is inspired by annealing in metallurgy. It consists in heating the metal to a high temperature and then slowly cooling it. In this way, the internal structure of the metal is first broken and then very slowly "repaired". This results in a metal that has significantly better properties than at the beginning of the process.
