The KiWi core system is a flexible platform for building different kinds of semantic social software applications on top (currently the Semantic Wiki and the TagIT application). It provides all the core services required in such applications, like editing and tagging, the storage of content and associated meta-data, its own triple store, transactions and versioning over content and meta-data, a linked open data server, and many small features semantic social software developers will like (like convenience services for working with ontologies or SKOS thesauruses, etc.).
Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable. A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.
PottyMouth transforms completely unstructured and untrusted text to valid, nice-looking, completely safe XHTML. PottyMouth is designed to handle input text from non-technical, potentially careless, or malicious users. It produces HTML that is completely safe, programmatically and visually, to include on any Web page. You don't need to make your users read any instructions before they start typing. They don't even need to know that PottyMouth is being used.
Depends is an embeddable, generic dependency tracker library for C++. The Depends class implements a complete dependency tracker and an associative container for any given value-type. It can be used as-is without any real knowledge of how it is implemented, although extensive documentation of the implementation is included and can increase productivity.
DisTract is a distributed bug tracker. DisTract allows you to manage bugs in a distributed and potentially offline manner through your Web browser on your local machine. The distribution is achieved by making use of a distributed software control system, Monotone. Thus Monotone is used to move files across the network, perform merging operations, and track the development of every bug.
