Apache Accumulo provides prefix encoding via something called "Relative Key Encoding"[1]. This amounts to removing identical portions of consecutive keys. For example if a key begins with '20191104_1' and the next key is '20191104_2' we don't need to store all bytes for the identical prefix. Instead we can store we... [Read More]

Managing Resources I’ve been hacking away at a robotic car built with a RaspberryPi. I had no way of monitoring the battery life, so it occurred to me that we need such a mechanism in MiNiFi C++. Configuring MiNiFi C++ for the correct number of threads and timing can be... [Read More]

Visualizing Temperature and Humidity Sensors to monitor my furnace As I've previously discussed with 'Navigating IoT,' I think that IoT is such a general initialism that we can't fully capture what is possible. One of the primary areas technologists refer to is sensor capture. Unlike most posts that discuss this,... [Read More]
