Red Hat Network

Red Hat Network (abbreviated to RHN) is a family of systems-management services operated by Red Hat. RHN makes updates, patches, and bug fixes of packages included within Red Hat Linux and Red Hat Enterprise Linux available to subscribers. Other available features include the deployment of custom content to, and the provisioning, configuration, reporting, monitoring of client systems.

Users of these operating systems can then invoke the up2date or yum program to download and install updates from RHN. The updates portion of RHN is akin to other types of automatic system maintenance tools such as Microsoft Update for Microsoft Windows operating systems. The system requires a subscription to allow access to updates. (Red Hat's yum and Advanced Packaging Tool repositories provide free access to updates for Fedora systems.)

On June 18, 2008 Red Hat CEO Jim Whitehurst announced plans for the RHN Satellite software to be open-sourced following the Fedora/RHEL model. Subsequently, project Spacewalk was launched.

Power user

A power user or experienced user is a computer user who uses advanced features of computer hardware, operating systems, programs, or web sites which are not used by the average user. A power user may not have extensive technical knowledge of the systems they use and is not necessarily capable of computer programming and system administration, but is rather characterised by the competence to make the broadest or most general use of computer programs or systems. In enterprise software systems, "Power User" may be a formal role given to an individual who is not a programmer, but who is a specialist in business software. Often these are people who retain their normal user job role, but also function in testing, training, and first-tier support of the enterprise software. Users may erroneously label themselves as power users when they are less than fully competent.

Some software applications are often regarded as being particularly suited for power users, and may even be designed as such, due to their inclusion of sophisticated function and feature sets not typically found in other comparable applications. Examples include VLC media player, a multimedia framework/player/server, which includes a complex, feature-rich, and highly customisable interface (and multiple interfaces moreover, beyond simple skinning) with numerous built-in capabilities not typically deemed useful or even understandable to users in the context of other media player suites such as Windows Media Player or iTunes
