Amber sits in the tcpserver chain for qmail and implements an "amber list" for incoming mail. This neither accepts nor rejects connections, but implements a number of timing-related tricks to fake out spam and virus software that doesn't implement SMTP correctly. For example, it can defer requests from new IP addresses for a few minutes before it starts passing connections on to smtpd, pause and check for programs that send data before the HELO, and otherwise make things rough for bandit bulk mailers.
The PKSampler is a live DJ tool. It is different from other "live DJ tools" in that it focuses on allowing the user to mix many samples at once. The focus is on a simple touchscreen interface that allows quick access to user-supplied loops and samples. The user interface is driven by Python and Qt, and uses 3d POV-ray images for widget animations.
Wumi is a sendmail milter using the py-milter. It rejects mail containing certain (configurable) attachment filenames (.exe, .pif, etc.) or containing a virus (checked by calling a single-user license command line scanner) by answering the SMTP DATA step with "554 5.7.1". This way, the mail server does not have to generate senseless bounces.
The Better String Library is an abstraction of a string data type which is superior to the C library char buffer string type and C++'s std::string. Among the features achieved are substantial mitigation of buffer overflow/overrun problems and other failures that result from erroneous usage of the common C string library functions, significantly simplified string manipulation, high performance interoperability with other libraries that expect '\0' terminated buffers, high performance common string operations, and functional equivalency with other more modern languages.
PHP MIME Mail decoder class is a PHP class to parse and decode MIME email messages. It supports decoding single RFC 2822 MIME messages or archives that aggregate multiple messages in the mbox format. It can decode messages read from files or data strings. The bodies of multipart messages can be decoded into distinct sub-messages. Optionally, the message body data can be saved to separate files, so the class can handle messages larger than the available memory. The parser can tolerate some syntax errors in malformed messages that are not compliant with RFC 2822.
Essential Management is a multi-user project management system for managing intricate and complex information. Its initial purpose was to allow software development teams to create, maintain, track, and store project requirements on a multi-project basis in a multi-user environment. It has now become more abstract in the type of data it can maintain, allowing the easy addition of new data models and other expansions. Information can be stored in any of several database management systems, and can take advantage of a networked DBMS.
