How to JOIN datasets in Polars … compared to Pandas.
It’s been a while since I wrote about Polars on this blog, I’ve been remiss. Some time ago I wrote a very simple comparison of switching from Pandas to Polars, I didn’t put much real effort into it, yet it was popular, so this is my attempt at trying to expand on that topic a […]
Building Databricks Data Pipelines 101
Have you ever wondered at a high level what it’s like to build production-level data pipelines on Databricks? What does it look like, what tools do you use?
How To Build and Open Source PYPI Python Package
Ever wondered how to build and end-to-end project for an Open Source Python Package that gets published to PYPI? I built out lakescuman open-source package to help with Databricks Unity Catalog Delta Lake tables querying with Polars, DuckDB, or PyArrow. https://github.com/danielbeach/lakescum

Don’t Be So Smart
Most Software Engineers think of themselves as too smart. They think they are the best and brightest coder alive or that has ever lived.

Never Put Databricks Notebooks in Production
Recently an Architecture at Databricks recommended people use Notebooks for Production workloads. Very bad and horrible idea. Very expensive compute for most people (All Purpose Clusters) and it leads to horrible development practices. It set off a firestorm on Linkedin when I commented people SHOULD NOT follow this advice.

The Best Piece of Software Engineering Advice
You probably think this is another internet clickbait title uh? Just trying to get you to clickty clickty and sell you some Google Ads. Two problems. I don’t have Google Ads, and I know a small percentage of people will actually listen to this advice. Whatever. There is a reason some developers struggle to move […]
