Resources that I thought were especially useful or creative.
Compiler Explorer: Compare code from a variety of languages with the compiled assembly with different compiler flags in a hihglighted, side-by-side format. Very useful if you are learning software reverse engineering.

SQL Murder Mystery: Another engaging introduction to SQL.
REPL: Great pair programming tool. Named after the read-evaluate-print loop computing environment, this web-based IDE is great for working on a project with friends or teaching.
The Deadlock Empire: A fun introduction to some concurrency pitfalls. Don’t worry about the C# orientation. You’ll learn things that you can apply to any language.

Oh Shit, Git!?!: For when you stray from the happy path.
