irked is an IRC client that runs as a daemon accepting notification requests as JSON objects presented to a listening socket. It is meant to be used by hook scripts in version-control repositories, allowing them to send commit notifications to project IRC channels. A hook script that works with git, hg, and svn is included in the distribution.
PHP OAuth API authorizes user access using the OAuth protocol. It abstracts OAuth 1.0, 1.0a, and 2.0 in the same class. It provides built-in support for popular OAuth servers: Bitbucket, Box.net, Dropbox, Eventful, Facebook, Fitbit, Flickr, Foursquare, github, Google, Instagram, LinkedIn, Microsoft, RightSignature, Scoop.it, StockTwits, Tumblr, Twitter, XING, and Yahoo!. Every other OAuth server is supported by setting an endpoint URLs and other parameters using specific class variables. The class can also send requests to an API using the previously-obtained OAuth access token. For servers which support offline access, the class can renew expired tokens automatically using refresh tokens.
Derrick is a simple tool for recording data streams of TCP and UDP traffic. It shares similarities with other network recorders, such as tcpflow and wireshark, though it is more advanced than the first and clearly inferior to the latter. It has been specifically designed to monitor application-layer communication. In contrast to other tools, the application data is logged in a line-based ASCII format. Common Unix tools, such as grep, sed, and awk, can be directly applied. Even replay of recorded communication is straightforward using netcat. Derrick supports on-the-fly compression and rotation of log files.
The KoreLogic Expression Language Library (libklel) is a C library that provides a simple expression language that can be embedded in other programs. It does not implement a full programming language, but rather a simpler expression language called KL-EL that is designed to provide arithmetic and logic operations in situations where embedding a full programming language would be overkill. KL-EL can access functions and variables exported from the embedding program, and is statically and strongly typed, which helps ensure that expressions are valid before they are executed. The embedding API is easy to use, and the library itself is very small.
