The Missing Semester of Your CS Education is an educational website and course material collection that teaches practical computing skills often omitted from traditional computer science curricula.
The project addresses gaps in formal CS education by covering tools and techniques that working developers use daily but rarely encounter in academic settings. It provides lecture notes, exercises, and video content organized around topics like command-line tools, version control, debugging, and system administration. The material is structured as a self-contained course accessible through a website built with Jekyll.
The course suits students and early-career developers who want to fill knowledge gaps in practical tooling and workflows. It works well as a supplement to formal education or as self-directed learning for those entering software development. The material is freely available and licensed for broad reuse and translation, making it accessible to learners worldwide.
The project accepts contributions through pull requests and issues, indicating openness to community involvement in expanding and refining the course content. Development can be done locally with Ruby and Jekyll or in a Docker container, lowering barriers to contribution. The codebase is maintained in a way that supports both direct editing and containerized workflows for contributors with different development environments.
