  • Pavlov’s Sandman pt 3: Hacking a Shock Collar and the benefits of Propper Cargo Culting

    Posted by rawkintrevo on May 30, 2018May 23, 2018

    In the last post I laid out a super simple algorithm for detecting snores.  You might have read that and thought, “dude, this barely counts as data science”. I would agree with you.  I did that in …

  • Using JNIs (like OpenCV) in Flink

    Posted by rawkintrevo on August 14, 2017August 14, 2017

    For a bigger project which I hope to blog about soon, I needed to get the OpenCV Java Native Library (JNI) running in a Flink stream. It was a pain in the ass, so I’m …
