#4: AsyncDisplayKit


AsyncDisplayKit is Facebook’s  source of smooth, responsive asynchronous user interfaces for iOS apps.

#5 Lwan Web Server

Lwan is a high-performance & scalable web server for glibc/Linux platforms. In development for almost 3 years by Leandro A.F. Pereira, Lwan was until now a personal research effort that focused mostly on building a solid infrastructure for a lightweight and speedy web server with a low memory footprint, minimal system calls, a hand-crafter HTTP request parser and a C code base of roughly 7,200 lines. Lwan is now transitioning into a fully working, capable HTTP server with features including a mustache templating engine, Python test suite and an API.
