Hello World

I’m Mark Freeman — Data Engineer, O’Reilly Author, LinkedIn Learning Instructor, and Open-Source Developer.

Why an IDE Theme?

I spend most of my time in an editor, so I figured my website should feel like one. Four switchable themes, an interactive terminal, tabbed navigation, a file explorer — it’s all here.

What’s on the Site

Try the Terminal

Hit Ctrl + / to open the terminal below and type help to see what you can do.

greeting = "Hello, World!"
print(greeting)

More posts coming soon. Thanks for stopping by.
