The HP Linux Common Operating Environment (LinuxCOE) is a global engineering program which facilitates provisioning and lifecycle support of Linux systems. Key deliverables are to increase reliability, availability, maintainability, and performance of global infrastructure and production environments by maintaining a minimum number of platform and component configurations.
SLACK (Sysadmins' Lazy Auto-Configuration Kit) is a configuration management system designed to appeal to lazy system administrators. It's an evolution from the fairly common practice of putting files in some central directory. It's descended from an earlier system called "subsets", and uses a multi-stage rsync to fix some of the problems in that system.
Virt-Factory is a framework for managing a large number of Xen virtual machines, such as might be found in data centers or large lab configurations. It works by managing a pool of registered physical hosts and then deploying virtual machines, which have specific roles as defined by their "profiles" (profiles act as shareable virtual appliance definitions), onto those hosts. Virt-Factory provides both a Web UI (for ease of use) and an XML-RPC API (for scripting of admin actions). A command line interface (along with other advanced batch management features) is coming soon.
JNC (JavaNativeCompiler) is a Java to native compiler. It allows ahead of time compilation of your Java applications. With JNC, you can create real standalone native binaries which will no longer depend on a JRE. This is especially useful when applications have to be deployed to end users. Native applications are easier to deploy since the end user doesn't need to worry about JRE dependency. They are also harder to decompile, and they load more quickly.
FREP is an application which can be used to keep files in a cluster of servers synchronized from a centralized location. Under the hood, it uses the Spread toolkit (broadcast/multicast traffic), libevent/epoll, sendfile, inotify, intelligent file transfers using the generic diff format, and zlib compression.
PHP Tarbackup is a simple class that allows backing up an entire Web site. It automatically works around timeout limits by splitting the job into multiple requests, allows tarball archive creation and updates, and comes with the Veloce script, which is very useful to automatically unpack tar.gz archives remotely and skip long waiting times due to FTP uploads.
