Imagine you have a Nodejs server with endpoint that performs heavy CPU operations. By default your server runs on a single thread. This means it will freeze depending on the CPU load. If your server has other asynchronous endpoints, for example, to execute database operations, those endpoints would become unresponsive while the heavy load endpoint is processing. Our first idea is to create more th
Most developers like to believe that a good product will eventually speak for itself. Sometimes it does. More often, it quietly sits on the internet, perfectly engineered, carefully documented, and almost completely invisible. That is not because the product is bad. It is because the web is crowded. Search engines, communities, newsletters, blogs, GitHub repositories, comparison pages, and documen
When building modern applications, one problem shows up everywhere: How do I uniquely identify data across systems? That’s where UUIDs (Universally Unique Identifiers) come in. A UUID is a 128-bit unique identifier used to identify information in distributed systems. Example: 550e8400-e29b-41d4-a716-446655440000 It looks random - and that’s the point. Traditional IDs (like auto-increment integers
Every dev team has lost hours to .env problems. A missing variable breaks a deploy. I built Razify to make all of that stop happening. Razify is a single binary CLI tool for .env file management. No cloud account No tracking No Go installation required Works with Node.js, Python, Ruby, Laravel, Rails — anything that uses .env files. razify scan .env Detects leaked secrets using 80+ regex patte
I got tired of not knowing why users were dropping off in my app. Heatmaps show you where people click. Analytics show you when they leave. But nothing tells you how they felt while using it. So I built SessionMood API — a REST API that scores user mood in real time based on behavioral events. You send behavioral events from your frontend: fetch("https://session-mood-api-production.up.railway.app/
There's a quiet shift happening in how AI tools interact with users, and most developers haven't noticed yet, because just one week after the MCP Apps specs were published by Anthropic, OpenAI launched a huge marketing campaign around OpenClaw and they got all the attention, at least for a while. For the past two years, every AI assistant has been stuck behind the same interface: a text box. You a
Thanks to AI, I've spent more time architecting and building apps, which means I spend a lot of time looking at frontier models and agonizing over token use. I’ve also been battling a very modern affliction: token consumption anxiety. It feels modern AI-powered app architecture is asking us slaps an LLM at the front door. You want to dynamically pick the best model for a specific task? Great, the
