a Guided Introduction to Elixir - Part 4 of 6
summary
Walks through building a real parallel map and shows parallel_map using spawn+refs and why ordering and mailbox scanning matter, demonstrates that htop reveals work spread across cores, and reproduces a Phoenix example where one hot process blocks only its request while others stay fast. Explains GenServer lifecycle, naming and start_link return tuples, and contrasts gen_server handle_call vs handle_cast with blocking behavior and state returned as a new list. Mentions tools like htop and OTP and that the code is practical not hypothetical.
