I Added ML Anamoly Detection to My Cybersecurity Tool - Here's What the Numbers Actually Showed

A few weeks ago, I built Log Sentinel, a log analysis dashboard that detects brute force attacks, directory scanning, and error spikes in Apache server logs using rule-based detectors. The rules worked well, but I kept wondering: what would a machine learning model catch that my rules missed? And mo...

The Repository Pattern in NestJS: a collection that happens to live in a database

The canonical starting point for a NestJS module backed by TypeORM is the one the framework itself documents: the module declares TypeOrmModule.forFeature([Order]) and the service receives the repository by injection. @Injectable() export class OrderService { constructor( @InjectRepository(...

I built a WhatsApp/Telegram group directory with zero coding background — here's the whole, unfiltered story

I'm not a developer. I want to say that upfront, because it matters for everything that follows. This isn't a polished "here's my SaaS" post. This is the real version — the version where I almost gave up twice, broke my own security without knowing it, got rejected by every directory I tried to use...

I checked what 6 AI coding tools write to disk to stop the agent forgetting its plan. Half write nothing.

Every AI coding tool has the same top complaint: "it forgot what we were doing." I spent weeks assuming that was a context-window problem. It mostly isn't. It's a filesystem problem — and you can predict which tools suffer from it by asking one question: where does the plan get written down?...

An open-source, modular CMS for developers and AI-assisted/vibe-coded websites.

For years, the CMS ecosystem has largely followed the same formula. Install a CMS. Choose a theme. Install plugins. Customize some templates. Add an API when you need one. Then, eventually, try to connect everything to AI. But the way we build software has changed. Developers increasingly work al...

How to Safely Fetch Metadata from User-Submitted URLs (Without Getting Hit by SSRF or DNS Rebinding)
