Warewulf is an operating system management toolkit designed to facilitate large scale deployments of homogeneous and heterogeneous systems on physical, virtual and cloud based infrastructures. Originally, the Warewulf project pioneered the concept of stateless computing in HPC, setting the standard for large-scale cluster provisioning. It provided two functions, provisioning and monitoring but the two functions did not communicate within Warewulf itself, nor was it possible to hook other functions directly into Warewulf itself. Today, Warewulf is more than just a basic provisioning and monitoring solution as it now implements an abstract, object-oriented data store and a modular interface that facilitates a highly extensible, customizable feature set. Current and planned modules include monitoring (operating system, services, filesystems, etc.), provisioning, power management, user management, configuration management, event/trigger handling and notification, scheduler integration, cloud services (both local and remote), etc.
Tupd is a trustworthy daemon that reports uptime statistics via HTTP. Tupd is designed to be small, simple, and secure. These features make tupd suitable for use on critical servers and firewalls where a full HTTP server and script installation would pose an unacceptable security risk.
The Working Overloaded Linux Kernel (WOLK) project provides stable and development kernels for either server or testing purposes. These kernels provide a server kernel and also a service for developers and end users who can't be up-to-date with the latest kernels/patches but want to test new kernel features. Patches may be added upon request.
Valgrind is a tool that helps you find memory management problems in programs. When a program is run under Valgrind's supervision, all reads and writes of memory are checked, and calls to malloc/new/free/delete are intercepted. As a result, Valgrind can detect problems such as use of uninitialized memory, reading/writing of memory after it has been freed, reading/writing off the end of malloced blocks, reading/writing inappropriate areas on the stack, memory leaks in which pointers to malloced blocks are lost forever, passing of uninitialized and/or unaddressable memory to system calls, and mismatched use of malloc/new/new  vs. free/delete/delete .
PHPX is a Web portal system, blog, Content Management System (CMS), forum, and more. It is designed to allow everyone to be able to have feature-rich, interactive websites even if you do not know a bit of programming. Some key features include fully-integrated forums, downloads, an image gallery with slideshow and auto-thumbnailing, support ticket system, a GUI interface for Web page content management, news with topics and instances, and a whole lot more. It allows you to fully customize the look of your site.
