What Can You Learn Here?

We group materials around four layers of the software stack and keep adding as we go along.

  • Presentation - HTML, CSS, JavaScript, Solr Search
  • Programming - Python Scientific Stack
  • Database - MySQL and MariaDB
  • Operating System - Linux (command line)

If Excel is your thing, our Finance tutorials utilize spreadsheets and make the transition to programming easier.

Our Approach

The coding language landscape changes fast and it's easy to waste time. To help, we create freely-accessible and professional-quality tools that don't wander far from the command line.

For example, instead of tutorials on third-party software like WordPress we focus on the code behind the scenes, HTML and CSS, in this case. This provides more freedom and flexibility down the road.

Yes, the learning curves are steep and there's more up-front work, but over time you'll be more valuable and more marketable.

Tutorials are published on YouTube and in print here so you can see code examples and follow along.
