Optimizing Lists in React - Solving Performance Problems and Anti-patterns
React is the most popular front-end framework, and that’s for a reason. Besides being funded by one of the largest companies on the planet, it’s also built around a few key concepts (one-way data flow, immutable data, functional components, hooks) that make it easier than ever to create robust applications. That said, it’s not without pitfalls.

12 Rust Tips and Tricks you might not know yet
Rust is a great programming language: reliable, fast, enjoyable, but also rather complex. Over the past two years, I’ve been using it both professionally and on side projects (such as Espanso) and, over that time, I stumbled upon many useful patterns and crates that I wish I knew when I first started learning it.

Why Electron is a Necessary Evil
Unless you’ve been living under a rock for the past 5 years, chances are you have used an Electron-based application at least once in your life.

Regex101 - The Ultimate Tool for Regular Expressions
If you've been programming for a while, you will surely know how useful regular expressions can be when dealing with text. You may want to validate a string (such as checking whether an email field is valid) or extract some information from formatted text. In both cases, building the right regex can take many attempts.

How to Promote Your Open Source Project
As a developer myself, I know how hard it can be to promote a project. You spent weeks, months, or even years, developing your idea, only to find out later that nobody is noticing it. Turns out that promotion, probably the least favourable thing for a programmer, is important as well.

How to Force Github Pages to Rebuild Jekyll Website
A month ago I decided to rebuild my website using Jekyll for a couple of reasons: it’s the official tool used by Github Pages and it supports blogging.

Turn Telegram into a Static Web Server with TLGUR
Telegram is one of the most popular messaging apps and probably the most loved by developers. The reasons are many, but I think that it mostly boils down to their openness, which led many programmers to create unique and interesting projects around it. Today I want to share one of those: TLGUR.

Learning How to Type Properly Makes You a Better Programmer
