104: Exploring Our Data with Chris Grainger

Chris Grainger explains Explorer, Nx's recent addition. It's a “Data Frame” library which sounds far more nebulous than it is. It lets us explore and manipulate two-dimensional data like we already do with DB tables, spreadsheets, CSV files, etc. Only this works in memory, is faster, and has predefined functions that make it very powerful. Explorer fills an important slot in the overall pie for data science and ML in Elixir. However, Explorer is also one of the tools that “regular” Elixir devs can take advantage of today!

Maintain that attitude and any frustration or entitlement you feel will be replaced with gratitude. Better for maintainers, and better for you.” Do you have some Elixir news to share?
