slackroll is a package or upgrade manager for Slackware Linux. It is designed to work with official mirrors in systems mainly composed of official packages with a few unofficial packages. It lets you automatically upgrade or install packages, and displays which packages have been added or removed from the Slackware tree.
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.
Vamos project allows computers to run software directly from the network, without installations. The software is stored on servers and is centrally maintained without the user's effort or attention. The user just needs to run applications, and the necessary bits are streamed automatically to its computer. The execution of the software is local, allowing high responsiveness and distributed computational load.
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.
W-Packager is a packager similar to dpkg that can be used by anyone to create and maintain Debian packages under Linux or other Unix systems. The aim of the project is primarily to have a workable version of a packager that can be compiled on many systems, including those that do not support fork(). At this time, W-Packager is used within UniGW. It can also be used under Linux.
