Finding penguins with a snake Linux features for a Python user
summary
Concrete demos show how Python calls fork+exec (the subprocess source uses them), how stdio is just a file descriptor under /proc/self/fd, and how buffering explains delayed output. The talk walks through registering atfork handlers, signal behavior (SIGINT -> KeyboardInterrupt, SIGPIPE -> BrokenPipeError), blocking semantics of named pipes, and bidirectional unix domain sockets via socketpair. Examples run live and are reproducible; the membrane codebase is cited as a real project to read for working implementations.
