Made a simple uptime monitoring system using FastAPI + Celery

Hey everyone, I’ve been trying to understand how tools like UptimeRobot or Pingdom actually work internally, so I built a small monitoring system as a learning project. The idea is simple: users add endpoints background workers keep polling them at intervals failures (timeouts / 4xx / 5xx) trigger alerts UI shows uptime + latency Current approach: FastAPI backend PostgreSQL Celery + Redis for p...

Built an API monitoring tool (UptimeRobot-style) while learning backend — feedback?

I’ve been working on a project called Sentinel for a while now. Initially, I just wanted to understand how tools like UptimeRobot or Pingdom actually work internally — especially things like polling systems, background workers, and multi-tenant architecture. It ended up becoming a full project 😅 What it does You can: Monitor your APIs/endpoints (GET/POST) Set custom intervals (like every 30s, 60s...

ThreatsDay Bulletin: FortiGate RaaS, Citrix Exploits, MCP Abuse, LiveChat Phish & More

ThreatsDay Bulletin is back on The Hacker News, and this week feels off in a familiar way. Nothing loud, nothing breaking everything at once. Just a lot of small things that shouldn’t work anymore but still do. Some of it looks simple, almost sloppy, until you see how well it lands. Other bits feel a little too practical, like they’re already closer to real-world use than anyone

Deep Dive into the RUXAILAB Codebase: Understanding Architecture for A/B Testing Integration

When I started exploring RUXAILAB, my goal was not just to understand how the platform works, but to figure out how a new system—A/B testing—could be integrated without disrupting its existing workflow. Instead of approaching the repository as a collection of files, I treated it as a system. I focused on understanding how data flows through the platform, how different layers communicate, and wher...

I Built a Browser-Only Image Compressor with WebAssembly — Here's What I Learned

Every online image compressor I've used works the same way: upload to a server, wait, download. TinyPNG, iLoveIMG, Compressor.io — same deal. This always annoyed me. I'm sending my photos to some random server... just to make them smaller? My laptop has a perfectly good CPU sitting right there. And with WebAssembly, the actual compression algorithms (MozJPEG, OxiPNG) can run in a browser now. So...

Building a Spam Classifier using Machine Learning and Flask

Recently, I built a small project where I created a spam classifier that can detect whether a message is spam or not. This is part of my learning journey in Artificial Intelligence and Machine Learning, and I wanted to build something practical instead of just reading theory. 💡 Why I Built This While learning machine learning, I understood that just watching tutorials is not enough.

Circuit breaker in Go: surviving exchange outages

Binance announces maintenance at 2am. Your service keeps hammering it at 10 req/sec for 30 minutes. Result: 18,000 lost requests, goroutines piling up as each call waits for its timeout, and memory climbing steadily until the scheduler starts to struggle. A circuit breaker takes 50 lines to write. Binance maintenance is inevitable. OKEx returns random 503s. Coinbase rate limits without warning. C...
