EP09 - Skynet 101, Dallas, Ruby on Rails and Data Science with Python

A conversation with Liz Johnson

Episode Summary

This week on the Carolina Code Cast, host Barry Jones chats with Liz Johnson, Staff Software Engineer with Silicon Hemisphere. During this episode, Barry and Liz talk about her talks at PyCon and PyData around Python, AI and data science as well as her experience with PHP+Laravel and Ruby on Rails. Liz explains Vectors and TFIDF (Term Frequency - Inverse Document Frequency) in a manner that even Barry can understand. We learn about family and tech life in Dallas, as well as getting into writing and publishing tech content in the first place. Great and informative episode!

“I've always told people who are considering publishing more content, do it because it's a really good learning experience. To try to teach someone something, you have to know it really deeply yourself.” - Liz Johnson
