⚡ TL;DR: Internalize the single-threaded event loop and the sync, microtask, macrotask ordering it enforces. That one model explains promises, event delegation, and why a long task freezes your UI, plus how to avoid…
A Steam wishlist campaign needs links that tell you which channel a visitor came from. Here is the small helper we use for our October studio posts. It generates one URL per game and channel, so the copy and the link…
Every Chrome extension I install asks for something. Read and change all your data on all websites, usually. So when I built five small developer utilities as extensions, I wanted to know how far I could get with the…
State Lifting in React When building a React application, different components often need to share the same data. Normally, each component can manage its own state using the useState hook. However, when multiple…
Series: Building PdfWord — a free, no-backend PDF tools site (Part 16) Nobody searches for "PdfWord." Why would they — it didn't exist until I built it. People search for "merge pdf without account", "compress pdf for…
Most hospital EMR systems treat clinical encounters as structured text or generic intake forms. When building Dentiva, a clinical management platform for dental practices, we hit an immediate engineering wall: dentistry…
I love Node.js. It's why I can ship a backend in an afternoon. But I also write firmware and deal with edge hardware — OpenWrt routers, MIPS boards, small ARM gateways. And on that class of device, Node.js is often just…
Cloud video compressors are one of the most frustrating traps on the web: "Your video exceeds the 500MB free upload limit. Please upgrade to Pro for $19.99/mo to continue." Why are developers transferring gigabytes of…

An AI video job can keep running after the user refreshes the page. The browser loses its component state, but the generation service still has work to do. When the page comes back, the UI needs to find that job, resume…
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass The "Desk-Lock" Dilemma: A Tale of Two Screens Let’s be brutally honest for a second. As software developers, our daily routine…
