Stupa is an associative search engine. It lets you search related documents with high performance and high precision. Since document data and inverted indexes are kept in memory, Stupa reflects updates of documents in search results in real time. A server implementation of Stupa is possible by using Thrift.
WebSecure4Linux is a simple, unofficial Linux client for the Freedom WebSecure service (see http://www.freedom.net/products/websecure/). Zero-Knowledge Systems runs the service and provides a Windows client, but is not responsible for this Linux client. Note that you will need to sign up for the service before this client will operate. It currently supports HTTP on all versions of Linux, and HTTPS is supported under Linux 2.4. WebSecure4Linux is not feature-complete and it is slow. It's written in Perl, and forks for each Web connection.
Fast Track Systems Monitor (FTMON) is a monitoring engine that can be integrated with other systems management vendor solutions. It also defines a standard that allows applications/devices to be instrumented rapidly. The intent is to allow writing an FTMON monitor for virtually every device or application, and that any detected problems from these monitors will be able to be forwarded to any systems management solution. It is currently completely configuration file based.
PaulA intends to be a (lib)CIM-based administration system for Linux written in Perl. It provides a (very basic) CIM Object Manager (CIMOM), a sample CIM Client for testing purposes, and a repository to store "static" CIM entities. The CIMOM has the ability to communicate with Providers, which supply "dynamic" CIM entities. PaulA doesn't depend on a special distribution, because the Providers have the "knowledge" about the underlying Linux, and they can be exchanged.
