What Is HTTP Observatory? A Useful Tool for Checking Your Website

HTTP Observatory is a simple tool that checks your website’s security headers and basic protection settings. It helps you quickly review important items like HTTPS, HSTS, Content-Security-Policy, Referrer-Policy, and other common security headers. I added this tool to MTKits to make website security checks easier for developers and site owners. You can try it here: https://mtkits.com/http-observ...

Rate Limiting Your API: Token Bucket, Sliding Window, and Redis

Rate Limiting Your API: Token Bucket, Sliding Window, and Redis One abusive client sends 10,000 requests per second. Your database melts. Every other user gets 503s. Rate limiting is not optional. Fixed Window Count requests per time window (e.g., 100 per minute). Simple but has the boundary problem: 100 requests at 0:59 + 100 at 1:00 = 200 in 2 seconds. Sliding Wi...

You're Probably Comparing GPU Rentals the Wrong Way

If the first number you compare is hourly price, there is a good chance you are optimizing for the wrong thing. Open two pricing pages. Find the hourly number. Pick the smaller one. It feels rational, but it hides the variables that actually decide what the job will cost and how painful the workflow will be. What most people miss time-to-result matters more than hourly rate VRAM fit ...

Building Production AI Agents with LangGraph: Beyond the Toy Examples

Building Production AI Agents with LangGraph: Beyond the Toy Examples Every AI tutorial shows you a chatbot that answers questions. That's not an agent. An agent decides what to do, takes action, observes the result, and adapts. In production, it does all of that reliably, with audit trails, error recovery, and human oversight. LangGraph — the graph-based orchestration layer from LangC...

How I Run 10 AI Agents in Production (24/7 for 90+ Days)

Everyone builds demo agents. They work great in the terminal. You show them to your coworker, they say "wow." You feel like a genius for about forty-five minutes. Then you try to run them for real users, overnight, without you watching. That is when things get educational. I have been running AI agents in production for six months now — customer service bots, data analysts, internal tools, monito...

This must work on mobile including iOS. The problem iPhones record HEVC (H.265) by default. Every client-side approach I've tried fails on iOS Safari for large HEVC files: WebCodecs: VideoDec...
