This ONE weird trick makes React skip re-rendering entirely. The Hidden React Behavior: PS: Don't add bail-out condition using JSON.stringify initially itself while writing code as comparing using JSON.stringify is slower for larger objects. Use this as an optimization step. If you can calculate it from existing state/props, DON'T put it in useState. This bug pattern creates sync issues that haunt production. Storing calculated/derived values in state creates two sources of truth. They get out of sync, causing difficult-to-debug issues. Your codebase has 1000+ unused files and imports you don't even know about! Knip finds them ALL in 10 seconds. This tool is a game-changer! Dead code accumulates over time. Unused files, unused exports,…...

GPU stands for Graphics Processing Unit. In short, it's a chip designed to render graphics. So, why has a chip built for video games and rendering become the backbone of Artificial Intelligence? The short answer is: GPUs are beasts at parallel processing. But that one-liner doesn't do justice to the massive architectural shift we are witnessing. Today, we're going to dig into why the GPU became the engine of the AI revolution, starting from the grandfather of modern computing'the "Von Neumann Architecture"'all the way to the internals of the latest NVIDIA hardware. Before we talk about GPUs, we need to…...

Azure is a massive global cloud platform, and behind every service you use is a physical infrastructure carefully designed for reliability, performance, and compliance. In this guide, we'll break everything down step by step from the smallest server all the way up to Azure geographies using simple, beginner-friendly language. Servers: The Building Blocks of the Cloud At the heart of cloud computing is the server, a powerful computer that stores data, runs applications, and processes information.

26+ min ago (164+ words) This cheat sheet was originally published on SRF Developer. Check out the blog for more Flutter Widget guides. The Container is the "Swiss Army Knife" of Flutter. If you are coming from Web Development, think of it as a div. It lets you create a rectangular box that can be decorated with background colors, borders, shadows, and gradients. It combines common painting, positioning, and sizing widgets into one convenient package. Here is a copy-paste ready example showing a Container with Rounded Corners and a Drop Shadow (the most common use case): These are the properties you will use 90% of the time. The Container is powerful, but "heavy." If you only need to change the background color, use the ColoredBox widget instead. If you only need padding, use the Padding widget. Using specific widgets instead of a giant Container can make your…...

34+ min ago (382+ words) Then came the hard part. The part they don't always talk about in the success stories. Marketing. As a developer, my first instinct is to solve problems with code, not with marketing campaigns. And my second problem is a bit more specific: I'm based in Brazil. The Two Walls of Marketing for an Indie Hacker I quickly ran into two massive walls. Wall #1: The Time Sink Like many of you, I'd rather spend my time improving my product than trying to keep up with five different social media platforms. I actually built PostPulsar to solve my own problem of not having enough time for social media. But getting the word out requires a different kind of effort. Wall #2: The "Currency Wall" This is the killer. A modest ad budget of, say, $200/month might sound reasonable if you're earning in USD....

Two paths lay ahead: accept a comfortable job with visa security, or build something that could create real impact. This philosophy captured my journey with Nexus Beings. For a long time, the concept lived quietly in notes and sketches while I navigated life as an international student. Then came the obsession: building digital agents that don't just respond, but understand; systems that bring context, emotion, and intent to the world of service. I chose to build. Today, Nexus Beings has achieved proof of concept. Bootstrapping as an immigrant…...
