Easy Email SMTP is a class that can be used to compose and send messages via SMTP. It extends another class to compose email messages named Easy Mail. It overrides the messages sending function to use an SMTP class to send the message via an SMTP server rather than using the PHP mail() function.
Bitgate Server Software Environment aims to build a multi-protocol application environment in which server protocol handlers can be eventually loaded and unloaded on the fly using a center console or controller Web page. It aims to have 99.9% uptime, and have high-availability compliance. It is written in Java 6, and relies completely on Java's I/O functionality to provide non-blocking support for both SSL and non-SSL sockets (without having to know how to use SSLEngine). All configuration is done via XML files, as this is easier to maintain. It includes a minimal demonstration HTTP server.
Apophenia is an open statistical library. It provides functions on the same level as those of the typical stats package (such as OLS, probit, or singular value decomposition) but doesn't tie the user to an ad hoc language or environment. The core functions are written in C, but a Python interface is included. It supports SQLite and MySQL databases, exponentially expanding the upper limit to manageable data sets. Since the library is significantly faster than most stats packages, computationally-intensive procedures like maximum likelihood estimation and Monte Carlo routines are easy to implement.
