Continuations on the Web and in your OS
summary
Shows that delimited continuations let a server capture and store the exact continuation as a URL so forms resume where expected, implemented in the racket web server by keeping continuations in a dispatch table and prompting around servlets. Demonstrates server‑side components that encapsulate state, masks blocking I/O into an event loop for high‑throughput servers, and builds a cooperative threading kernel in ~12 lines plus a protected microkernel with syscalls and a shared “safe” in 50 lines of runnable Racket code.
