Most people use OpenTelemetry and SigNoz to watch their CPU usage, find memory leaks, or figure out why their API is taking 400ms instead of 200ms. But for the Agents of SigNoz Hackathon (Track 3: Observe Anything Weird), I wanted to do something completely different. I didn't want to watch hardware. I wanted to watch hackers. That is how Triage was born. It is an OpenTelemetry-powered Blue Team SOC (Security Operations Center) that tracks active cyber attacks instead of just generic application performance. The Original Vision vs. The Reality Building this sounded straightforward on paper: catch bad traffic, wrap it in an OpenTelemetry span, send it to SigNoz, and show it on a custom dashboard. But actually deploying this beast before the deadline was a completely different story. If you have ever tried to deploy a full-stack Next.js app, a Python honeypot, and an OTel pipeline while the clock is ticking, you know exactly what kind of panic I am talking about. Here is what actually happened behind the scenes. 1. The Azure VM & Docker Crash I started by spinning up an Azure virtual machine to self-host the SigNoz backend. I pulled the repo, ran docker compose up -d, and immediately watched my server completely freeze. Turns out, my free tier Azure instance (Standard_B2ats_v2) only had 1 GiB of RAM. You simply cannot run a massive ClickHouse database and a full OTel collector on 1GB of memory without it crashing instantly. I had to pivot fast and rely on the cloud endpoints. 2. The Vercel vs Localhost Trap Once I got the backend running, I hit my next wall. My Vercel Next.js dashboard kept throwing 500 Internal Server Error on the threat simulation API, and the SigNoz connection kept reading OFFLINE (fetch failed). I was staring at my logs losing my mind until it clicked. My Vercel environment variables had SIGNOZ_API_URL set to http://localhost:8080 and my Python script was looking for OTel on localhost:4318. Note to self (and everyone else): Vercel is a cloud serve

After living in multiple countries around the world and working remotely, I discovered that the best working cultures are asynchronous ones. An asynchronous working culture is a model where team members collaborate and complete tasks on their own schedules, without needing to be online at the same time or respond instantly. This means employees can work when and where they please for maximum productivity, often times companies who have succesfully implemented async communication have teams with

The UK MET office recently redesigned their site, adding a lot of additional whitespace, scrolling, and animations. This significantly reduced its usability for me, and left me wanting an ‘at a glance’ weather site. I made https://brolly.sh , a minimalist, plain text weather forecasting site. You can use it to view weather from around the world, with: 7 day forecast; Previous day log (so you can confirm it definitely was cooler / hotter / wetter / drier yesterday!); Hourly rain, wind, temperatur

SpinWin is an open source menu bar app to visually rotate any individual window. You can rotate / spin as many as you want one by one. I was scrolling reels when one came on where the content creator suggested "turning the phone upside down" for a portion. I was sitting at my mac, and decided to see if I could find something that did this. To my surprise, nothing exists, so I decided to build it. Turns out macOS doesn't provide any public API to do anything like this, so I wound up using the Acc

I recently found the Brooks Falls bear cam (Katmai, Alaska). It's become the calmest thing on my screen. It's peak salmon run right now, so it's basically bears and their all-you-can-eat salmon feast. But there's a bear that only fishes by belly-flopping at the salmon, and as far as I can tell has never once caught anything. I have no idea how it's still eating. A few others just sit in the water doing nothing at all. Here it is: https://www.youtube.com/watch?v=J7ZrIDvqlic What's yours?
