Hobby Projects

This serves as a repository of ideas that have popped into my head. As I have time, I play around with one.

1. Mute Button - Automatically mute television commercials using machine learning and Spark
2. NYC Taxi - A cabbie once told me that the length of each trip he takes is much longer than it was before. Use math to prove/disprove it. This data needs a lot of cleanup and profiling before it can be properly analyzed. NYC Taxi Data Cleanup Project
3. Heart Rate Anomaly Detector - Automatically detect afib in the fitbit HR
4. Picam Fun - Detect movements and objects from images work started here
5. Listicle - Organize online articles for reading frontend [backend](https://github.com/brycemcd/email-l
