cqueues is a comprehensive event and networking library for Lua 5.2 and LuaJIT using modern Unix O(1) polling facilities. It includes libraries for buffered socket I/O, SSL/TLS sockets, DNS querying, signal handling, threading, file change notification, and X.509 key management. It natively supports Linux, *BSD, OS X, and Solaris systems without third-party dependencies, and is interoperable with any event loop that accepts plain descriptors, or is usable standalone.
Unnamed un-names unwanted DNS entries. It was written to solve the problem of upstream DNS servers inserting bogus records for NXDOMAINs. It can be used to filter unwanted domain names like ads, porn, time wasters, etc. It is modular, so extensions are easy. Extensions can be written in Lua or compiled as shared objects.
