sxmppd is a server for the XMPP (Jabber) chat protocol. While other, functional XMPP servers exist, they are not as simple or have many dependencies. It supports user authentication, SSL, roster management, presence updates and subscriptions, messaging (local users), group chat, and file-based server configuration.
NSFFT is yet another FFT library for performing 1-dimensional fast Fourier transforms. It is a simple, small, and portable library, and it is efficient since it can utilize SIMD instruction sets in modern processors. It performs multiple transforms simultaneously, and thus it is especially suitable for digital signal processing.
The PHP7 Framework provides a hybrid API for easier Web application security. It adds an exceptional filter feature on the superglobal input variables, which can be used, for example, as '$_GET->filtered->text["easily"]'. The simplistic db() implementation adds easier parameterized SQL atop PDO. phunction is used as a bootstrapping framework, and LiveUser is included as a permission backend.
TeachToPod is a set of shell scripts for ripping DVDs from The Teaching Company to produce either video files (m4v) or audio files (mp3) for playback on an iPod. Metadata such as lecture titles are automatically scraped from the Web and added to the output files. Operation of the scripts is almost automatic, and from the operator's viewpoint requires merely physical insertion and removal of the DVDs. Presently, the scripts are optimized for iPod Classic and have only been tested on Ubuntu 10.10.
AffirmIt! is a supportive testing framework for Ruby. It tolerates all code, whether it exhibits behavioral challenges or not. It never uses the words "test" or "failure", which would imply a value judgment, or "assertions," which would imply an absolute truth. Instead, it treads softly around code and espouses preferences.
