Graphs are one of the most useful data structures. They can be used to model practically everything - object relations and networks being the most common ones. An image can be represented as a grid-like graph of pixels, and sentences can be represented as graphs of words. Graphs are used...

Originating from mathematics, graphs are now widely used data structures in Computer Science. One of the first problems we encounter when constructing any algorithm regarding Graph processing or traversal is how we represent the graph and then, how to traverse that representation. Graph traversal is not a trivial problem, and...
Graphs in Python can be represented in several different ways. The most notable ones are adjacency matrices, adjacency lists, and lists of edges. In this guide, we'll cover all of them. When implementing graphs, you can switch between these types of representations at your leisure. First of all, we'll quickly...

A graph is a great tool for modeling relationships between objects. Graphs can model complex relationships between any number of objects in a system, which makes them ideal for representing interactions between concepts/items in areas like physics, economics, chemistry. Thanks to constantly increasing computational power, you can manipulate graphs...
Kruskal's algorithm is one of the three most famous algorithms for finding a minimum spanning tree (MST) in a graph. MSTs are widely used to calculate optimal paths in a lot of different fields. From a post-office calculating the optimal path for a postman that needs to cover a certain...
Storing passwords securely should be imperative for any credible engineer. Plain text passwords are extremely insecure - you shouldn't even bother considering storing them a plain format. It's enough that someone gains view privileges on a database for an entire user base to be compromised. Passwords must be stored in...
Deep Learning models are very versatile and powerful - they're routinely outperforming humans in narrow tasks, and their generalization power is increasing at a rapid rate. New models are being released and benchmarked against community-accepted datasets frequently, and keeping up with all of them is getting harder. Most of these...

Next.js is an open-source JavaScript framework created by Vercel to enhance React applications with features such as Server-Side Rendering and Static Site Generation. Traditionally, React is used to create Single-Page Applications (SPAs) whose contents are rendered on the client side. Next.js extends this by allowing developers to create...

Vuex is a library that stores data in a Vuex store, which acts as the source of data on states in a Vue application. This store contains a global state (set of properties) and functions (getters, actions and mutations) used to read and alter the state. Consider a scenario in...
