Haskell Playground (WIP)
summary
A web playground is live at https://play-haskell.tomsmeding.com/ that runs real GHC compiled code written in Haskell and already serves as a runnable pastebin for #haskell IRC. The backend is horizontally scalable with a server coordinating many workers; workers spawn one isolated container per CPU core, run GHC, then destroy the container. Containers have no network, a ~100 MB disk, one-core limit and a 5s wall-time cap. Communications are signed with elliptic‑curve keys and the UI can show Core output.
