The article discusses a course called 'The Missing Semester of Your CS Education' which focuses on teaching students proficiency with their tools, such as the command-line, text editors, and version control systems. The course aims to fill a gap in traditional computer science education, where students often learn advanced topics but lack practical skills in using their tools. The course covers various topics, including debugging, packaging, and code quality, and also incorporates AI-enabled tools and techniques. The course materials and lectures are available online, and the course has been shared beyond MIT to benefit other students.
