Ready to have you mind blown by one of the coolest command line (Text User Interface) pieces of software I've seen in a long time?
Behold the awesomeness of adsb_deku!
While the name may not exaclty roll of the tongue... what it does is truly radical (in the 1980s sense of the word).
In short: It allows you to watch the flight paths of planes in your area. Visually. It's like a mini air traffic control center. In your Linux terminal.
Seriously. Check this out.
Keep watching. Then watch it again. Awesome.
Adsb_deku works by using a Software Defined Radio -- to capture ADS-B (short for Automatic Dependent Surveillance–Broadcast) data from 1090Mhz -- and then deserialize that data using the deku library ("ADS-B" deserialized using "deku"... hence the name "adsb-deku").
The results are then displayed using the Ratatui library (which is specifically for making visually impressive terminal applications).
Do I have any real, practical need for monitoring the planes in the sky using my terminal?
No. No, I do not.
But the fact that I can -- assuming I pick up a Software Defined Radio (which... now I feel like I have to) -- is freaking awesome.
