Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill. A poorly phrased

We’ve all been there—staring at a function that looks like it was written by an over-caffeinated goblin at 3 AM (maybe even your alter ego). You could pretend it doesn’t exist, or you could refactor it. Luckily, GitHub Copilot makes the second option less painful. Let’s get to it. What is code refactoring? Feel free to breeze past this section if you already know what’s involved with refactoring c
How modern browsers work
Note: For those eager to dive deep into how browsers work, an excellent resource is Browser Engineering by Pavel Panchekha and Chris Harrelson (available at browser.engineering). Please do check it out. This article is an overview of how browsers work. Web developers often treat the browser as a black box that magically transforms HTML, CSS, and JavaScript into interactive web applications. In tru

The string is arguably the most essential data type in programming — every programming language and software in the world uses strings in one way or another. It enables humans to easily communicate with sophisticated programs and machines. One thing that would help you a lot as a programmer is understanding how to use and manipulate strings so that you can build programs users love. Regular expres
Editor’s note: This article was updated in May 2025 to reflect changes in framework popularity, add newer Rust frameworks, and better align with developer sentiment in 2025. Rust is one of the most popular languages for developers because of its open source, fast, reliable, and high-performance features. When building a new API in Rust, it is important to consider the benefits and drawbacks of web
We've talked quite a bit about linting in the past two posts of this series, so I thought it's time to give eslint the proper limelight it deserves. Overall eslint is so flexible, that you can even swap out the parser for a completely different one. That's not a rare scenario either as with the rise of JSX and TypeScript that is frequently done. Enriched by a healthy ecosystem of plugins and prese
After almost three years since the initial design document and hundreds of CLs in the meantime, the V8 Sandbox — a lightweight, in-process sandbox for V8 — has now progressed to the point where it is no longer considered an experimental security feature. Starting today, the V8 Sandbox is included in Chrome's Vulnerability Reward Program (VRP). While there are still a number of issues to resolve be

Welcome to the “Awesome ChatGPT Prompts” repository! While this collection was originally created for ChatGPT, these prompts work great with other AI models like Claude, Gemini, Hugging Face Chat, Llama, Mistral, and more.

This article compares the performance of several different web servers for a Laravel-based application. What follows is a lot of graphs, configuration settings, and my personal conclusions which do not pretend to represent universal truth in any way. I myself have been working with NGINX Unit (+ Lumen) for a while, but I still see PHP-FPM being used in new projects quite often. When I suggest swit
Reading the excellent article by JeanHeyd Meneide on how broken string encoding in C/C++ is made me realise that Unicode is a topic that is often overlooked by a large number of developers. In my experience, there’s a lot of confusion and wrong expectations on what Unicode is, and what best practices to follow when dealing with strings that may contain characters outside of the ASCII range. This a
Rust from 0 to 80% for JavaScript Developers - Michael Salim | Senior Full Stack Freelancer and Startup Founder
This is a list of topic that will help you understand Rust quickly if you are a JavaScript developer. There are a lot of tutorial that start from scratch. But if you already know something else, why not compare them? These are differences that I wished I could refer to before starting Rust, kept short. Disclaimer! I’m very far from being well versed in Rust. These are how I interpret them and no m
I did this in 2020 and then again in 2021, but I’m in the mood to look around again. Let’s look through Are We GUI Yet? and see what’s up these days. The task today is to have a text label and an input field that can change the text in the label. In React, for example, this is basically free: const Demo = () => { let [state, setState] = useState("Hello, world!"); return ( <div> <p>{state}</p> <inp

Preamble In the expanding world of AI my heart still lies in AST transforms, browser fingerprinting, and anti-bot circumvention. In fact, that's the majority of this blog's content. But my workflow always felt... primitive. I was still manually sifting through page scripts, pasting suspicious snippets into an editor, and writing bespoke deobfuscators by hand.

React Best Practices – Tips for Writing Better React Code
By Jean-Marc Möckel Two years ago, I started to learn and use React. And today I'm still using it at my day job as a Software Developer and in my own side projects. During that time I've come across a lot of "typical" issues. So I searched around and found some best practices that I've integrated into my workflow, and I've come up with things that have made my life or my team members' lives easier
The sad state of property-based testing libraries Posted on Jul 2, 2024 Property-based testing is a rare example of academic research that has made it to the mainstream in less than 30 years. Under the slogan “don’t write tests, generate them” property-based testing has gained support from a diverse group of programming language communities. In fact, the Wikipedia page of the original property-bas

Bloom Filters - Much, much more than a space efficient hashmap! | Ben E. C. Boyter
Bloom Filters - Much, much more than a space efficient hashmap! 2020/12/10 (2440 words) A bloom filter is one of those data structures you are probably already aware of, or have at least heard about. For those looking for a simple recap, they are a probabilistic data structure which can be used to determine if something is in a set or not, giving a slight chance of returning a false positive resul
std::flip
std::flip is a little-known utility from the C++ standard library header <functional>: it is a higher-order function that accepts a Callable and returns an equivalent Callable with the order of its parameters reversed (or “flipped”). To understand how it can be useful, let’s start with a simple example. Consider the following tree node class: struct node { int value; node* parent = nullptr; node*

HTML Whitespace is Broken September 2, 2024Recently, I was working on a project which required a deeper understanding of how whitespace works in HTML. I was never a fan of HTML's whitespace behavior before as I've been burned by it a few times. But as I dug into it more deeply, I found myself discovering complex design issues that I wanted to explore in a blog post. This is partially to write down

Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
