What you'll build

You'll build a real-time incident radio for your backend that tails log files, detects important errors and warnings, and turns them into short, human-friendly summaries. It keeps a rolling memory of past issues, emphasizes the newest problems, and speaks each update aloud so you can stay focused while the system keeps watch.

Run it against any log file (for example, detector sample.log) and hear clear, periodic status reports about what's breaking and how it's evolving in real time.
