I made a kata on the dependency injection pattern before. The way I managed the dependencies was fine at that time. However, in a real life project, when the amount of dependencies grows, this may, and will turn into a hassle. The amount of imports and the boilerplate size becomes crazy high, and it basically gets repeated in every file!Read the post
I like automating things, so I try cutting edges where possible. One of the tiny annoying troubles bugging me was figuring the right live database to connect to, or the right cluster to select with kubectl, while knowing only a country name.

Making a weather indicator with ArduinoDo you recall that guy from a movie called "Zombieland", who used to have survival rules? Well, it is somewhat similar to the world of engineering. The demand for good engineers is (still) high, but the competition is even higher. So here is a list of insights I have managed to gather so far. Should you feel stuck with your career, or looking for new opportunities, perhaps this article can help you get off the ground.Read the post

For a software engineer once in a while it is good to make something that you can actually hold in your hands. Some people make ceramics, while the others sew or make paper models.

Back in times when I was working on a design system, I had to build a lightweight interactive demo environment to show off the capabilities of the library. Certainly, there are some canned solutions out there, but where is all fun in using something prefabricated? One can accept the challenge, and... Well, you know me.Read the post

For quite a while I was using Redux together with Redux Saga and was satisfied. Well, sort of, because I was constantly asking myself "Should the state management always be that complex?" Redux was a great library for it's time, when the concept of a centralized state was not well-coined yet. Nevertheless, one day came, and I have decided it was time to move.Read the post
