Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for
data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very
low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive
set of operating systems and processor architectures, and is currently in use on thousands of clusters around
the world. It has been used to link clusters across university campuses and around the world and can scale to
handle clusters with 2000 nodes.

Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks". Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more.It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects.

NFS was developed at a time when we weren't able to share our drives like we are able to today -- in the Windows environment. It offers the ability to share the hard disk space of a big server with many smaller clients. Again, this is a client/server environment. While this seems like a standard service to offer, it was not always like this. In the past, clients and servers were unable to share their disk space.
Thin clients have no hard drives and thus need a "virtual" hard-disk. The NFS mount their hard disk from the server and, while the user thinks they are saving their documents to their local (thin client) disk, they are in fact saving them to the server. In a thin client environment, the root, usr and home partitions are all offered to the client from the server via NFS.

In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache, MySQL and PHP) server up and ready to go. This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.The LAMP option means you don’t have to install and integrate each of the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications. Instead, you get increased security, reduced time-to-install, and reduced risk of misconfiguration, all of which results in a lower cost of ownership.Currently this installation provide PostgreSQL database, Mail Server, Open SSH Server,Samba File Server, Print Server, Tomcat Java Server,Virtual Machine Host,Manual Package selection,LAMP and DNS options for pre-configured installations, easing the deployment of common server configurations.

Pipelight, which allows to run your favorite Silverlight application directly inside your Linux browser. The project combines the effort by Erich E. Hoover with a new browser plugin that embeds Silverlight directly in any Linux browser supporting the Netscape Plugin API. He worked on a set of Wine patches to get Playready DRM protected content working inside Wine and afterwards created an Ubuntu package called Netflix Desktop. This package allows one to use Silverlight inside a Windows version of Firefox, which works as a temporary solution but is not really user-friendly and moreover requires Wine to translate all API calls of the browser. To solve this problem we created Pipelight.

LightZone is professional-level digital darkroom software for Windows, Mac OS X, and Linux. Rather than using layers as many other photo editors do, LightZone lets the user build up a stack of tools which can be rearranged,turned off and on, and removed from the stack. It's a non-destructive editor, where any of the tools can be re-adjusted or modified later — even in a different editing session. A tool stack can be copied to a batch of photos at one time. LightZone operates in a 16-bit linear color space with the wide gamut of ProPhoto RGB.
