I recently joined the biggest data project I’ve ever been a part of at work. It’s not necessarily huge by modern big data standards, but the main element I’m working on has over 130 million records, and takes up more than 5 Gigabytes on HDFS.

Welcome to the casual late morning/ early afternoon edition of the Coffee Log. I had a wild time at work last night preparing a machine learning demo for my company’s booth at The Atlantic Festival. As a result, I took the morning off and had a nice slow start to the day.
