I was looking through my old projects and found a couple of Rock-Paper-Scissors games I wrote in C a few years back. Why more than one? Because programming is fun, but also because I was experimenting. We're going to look at both versions and talk ab...

I spent six hours trying to upgrade a non-admin user to admin, convinced I was missing some clever bypass. The gap turned out to be one field in a request body I'd already looked at twice. This is a PortSwigger lab on multi-step process access contr...

My transcript downloaded as 2.txt. That was the entire vulnerability, sitting right there in a file name, and it took less time to exploit than it did to notice. This is a PortSwigger Web Security Academy lab, part of the access control section I've...

"Add rate limiting" sounds like one task. It's actually three separate layers, each defending against a different failure mode, with different trade-offs and different amounts of trust you can place in them. I only understood the distinction properly...

This is a breakdown of a decision I made building LogicVisor, not a general "streaming vs JSON" guide. AI API responses aren't limited to text: some return images, audio, structured data. I only needed text, so streaming vs JSON became a real fork in...

When I was building Logicvisorhttps://logicvisor.vercel.app/ — an AI-powered tool that reviews your algorithmic code, breaks down time and space complexity, and gives you the kind of feedback you'd want before a technical interview — I had to make a ...

First request to your AI model: timeout. Second request: instant success. If you've integrated AI APIs into serverless applications, you've probably hit this wall. Here's what's happening, why it matters for user experience, and how I solved it with...
