Bring your own floaties
MIT Missing Semester 2026
MIT’s crash course in ‘real-world’ coding sparks nostalgia, praise, and a sink-or-swim debate
TLDR: MIT launched its 2026 “Missing Semester,” a quick, practical class covering real-world coding basics from the shell to Git. Commenters celebrate the resource while sparking a debate over MIT’s sink-or-swim culture, reminiscing about volunteer crash courses and asking what’s changed since 2020—useful, timely, and a little spicy.
MIT just dropped its “Missing Semester 2026” lineup—a fast, practical mini-class that promises the stuff students actually use: shell basics, the command line, development tools, debugging, Git (the save-history for code), packaging and shipping, code quality and CI (automated checks), a life-after-code talk, and a big Q&A. The community loves the concept, but the comments quickly turn into a culture war over how MIT teaches.
The strongest vibe? Praise + nostalgia + debate. One fan says it’s an awesome course and points folks to prior Hacker News threads for extra nerd drama. Another commenter calls out the old-school MIT style: top schools toss you in the deep end and you learn to swim—“very good,” but also “learn Python on your own.” A veteran chimes in with history: MIT didn’t really teach programming; volunteers ran IAP (a January mini-term) pop-up classes like the legendary “Caffeinated Crash Course in C.” Cue jokes about “bring your own floaties” and coffee-powered bootcamps. A link-dropper adds a companion resource bernsteinbear.com/isdt, while another asks what’s new since 2020—answer: MIT’s own note explains updates on the 2026 development environment page. Verdict: the course slaps, but the sink-or-swim myth refuses to die.
