Opa is an open source, simple and unified platform for writing web applications. All aspects are directly written in Opa: Frontend code, backend code, database queries and configuration. And everything is strongly statically typed.
asyncoro is a Python framework for developing concurrent, distributed programs with asynchronous completions and coroutines. Asynchronous completions implemented in asyncoro are socket I/O operations (non-blocking sockets), database cursors, sleep timers and locking primitives.
NoPrint.js is a small and neat open source JS library that disables print, screenshot, copy and paste functions in HTML. You can also enable the AutoBlur option to let the content turn to blur once the mouse leaves the webpage.
