wtf is ooe-impf-alert?

This is a tool that automatically hunts for earlier COVID-19 vaccination appointments in Upper Austria and alerts you the moment one becomes available. If you already have a slot booked but want to find something earlier, you run this program in the background and it will notify you on your phone whenever it finds an opening that's sooner than your current date. The way it works is straightforward. You tell it which district you're interested in, what date you're trying to beat, and connect it to a free service called IFTTT (If This Then That). The tool then repeatedly checks the Upper Austrian government's vaccination database for available slots. Whenever it finds one earlier than your target date, it triggers a push notification through IFTTT so you get alerted immediately on your phone. This gives you a real-time advantage to book the slot before someone else grabs it. To use it, you need three pieces of information. First, you identify which vaccination center or district you want to monitor by finding its ID number from the official government API. Second, you create a free IFTTT account and set up a simple automation that sends a phone notification when triggered. Third, you run the program with your parameters, telling it which district to watch, what date to beat, and which IFTTT notification to trigger. The original creator built this for themselves during the vaccination rollout in Austria, and it's written in Go, a programming language that makes it easy to compile into a standalone program that runs on Mac, Windows, or Linux. This is the kind of tool that's useful in a specific time and place, during a vaccine rollout when appointment slots are scarce and people want to upgrade their timing. It's not a polished app you'd find in an app store, but rather a practical script that automates the tedious job of repeatedly refreshing a website looking for something better.
