The Event monitor project is an approach to network management based on message passing between manager and managed nodes. It's based on a client/server platform, where the server is the manager node, and all clients are managed nodes. This tool is under development, but has lots of features implemented, like a graphical console, message passing layer, one disk monitor and clients for sending messages (both API and binary forms are provided).
Heartbeat is a full-function high-availability system for Linux and other POSIX-like OSes. It monitors services and restarts them on errors. When managing a cluster (more than 1 machine), it will also monitor the members of the cluster and begin recovery of lost services in less than a second. It runs over serial ports and UDP broadcast/multicast, as well as OpenAIS multicast. It is easily adapted to different interconnect media and protocols. When used in a cluster, it can operate using shared disks, data replication, or no data sharing. Versions starting with 2.0 are comparable to any commercial HA package, providing resource monitoring, larger clusters, and detailed dependency information.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
Elektra is a universal hierarchical configuration store, similar to GConf and the Windows Registry. It allows programs to read and save their configurations with a consistent API, and allows them to be aware of other applications' configurations, leveraging easy application integration. While architecturally similar to other OS registries, Elektra does not have most of the problems found in those implementations. Elektra includes a library, an API, and commandline and GUI tools for administration tasks.
epto is a small library and framework for industrial strength shell script programming with sh. It features convenient error handling, tracing, logging, option handling, documentation template, process level transaction safety (sort of), and more. If one is used to shell programming, it takes less than five minutes of learning to start using it (see the crash course in the README file).
The goal of XPS is to make programming simpler by raising the level of abstraction without loss of performance. It provides true support for meta-programming and domain specific languages, making it possible to design simple programming languages to match the problem at hand. This is the opposite of current practice which seeks to translate the problem domain down into the low level solution domain of current programming languages.
