Does system design even matter? I’d like to start this with a short story. A senior software engineer named Devon recently joined a new company. He just got in touch with a system responsible for managing customer data. Since it’s something relativel...
Why Kubernetes? So far we talked a bit about virtual machines, docker and containers. It has become clear that abstractions can provide us with a lot of power. As developers, once we can abstract all the difficulties of managing a real environment an...
Docker images, containers… volumes? Last post we talked a bit about virtual machines, docker and kubernetes. We now know that virtual machines are software-based emulations of real machines that live inside a real machine. One real machine can have m...
What is kubernetes? Why docker? Is it any relevant? A lot of concepts and abstractions are involved when talking about docker containers and virtual machines and kubernetes. Let’s first understand the basics. A real machine is pretty much a processor...
If the main data structures (at least based on my experience) are Lists, Arrays and Maps, the remaining important ones are: Stack and Queue Tree I covered Lists and Arrays here, and Maps here. Now let’s talk about the remaining ones. Oh, a discla...
What are maps? I started writing about astral maps and storytelling but had to go back and delete everything because I remembered we are in the context of software development. I am considering using some map’s analogies, but they are actually not go...
As a senior backend engineer, which data structures must I know? All of them. And then some. I mean, it’s not really feasible to know everything about everything, but this is kind of what is expected from a senior backend developer. So we do the next...
What is a design pattern? Where does it come from? To where does it go? And why should I care? I’d say the main reason I got into studying design patterns is that I hate wasting time and effort. Design patterns in the end are just generalized solutio...
What are the differences between all of them? How do they all relate? There is one overlapping concept that goes into all of those: connecting systems. The main function of all of these is to connect two or more systems that want to communicate. And ...
