"How to set up for usage with yum (minimum required version: yum 2.4.x): RHEL5, CentOS, Scientific Linux, RHEL4 yum, SLES yum Note: The version of yum distributed on CentOS 3 by default is too old (yum 2.0.8). You will need to upgrade to a yum 2.4.x version in order to use these repositories. The older version of yum does not support plugins or mirrorlists, which are required for these repos to work. "
"Linux Explorer ( LINUXexplo ) is a script that collects software and hardware information about a linux server for support purposes, similar to the Solaris explorer ( SUNWexplo ) , Redhat's "sysreport" and SuSE's "siga" script. The script is designed to collect information about a server to help service departments support linux and have a common set of scripts for collecting information about linux no matter what distro users are using. The information is stored in seperated directories, once all the information has been collected it then tar's up those directories into a single gzip tar file which can then be attached to an email for your support organization or copied to a remote server for safe keeping.

Building and Promoting a Linux-based Operating System to Support Virtual Organizations for Next Generation Grids (2006-2010). The emergence of Grids enables the sharing of a wide range of resources to solve large-scale computational and data intensive problems in science, engineering and commerce. While much has been done to build Grid middleware on top of existing operating systems, little has been done to extend the underlying operating systems to enablee and facilitate Grid computing, for example by embedding important functionalities directly into the operating system kernel.
The Boot Process From the moment a user turns on a Mac OS X system to beyond the time the login window appears, Mac OS X executes a boot sequence that readies the system for use. If you provide system services to all users, you might need to execute some code during this process. The following sections explain the basic boot sequence and the places where your code can tie into it.
Need to monitor Linux server performance? Try these built-in command and a few add-on tools. Most Linux distributions are equipped with tons of monitoring. These tools provide metrics which can be used to get information about system activities. You can use these tools to find the possible causes of a performance problem. The commands discussed below are some of the most basic commands when it comes to system analysis and debugging server issues such as: Finding out bottlenecks. Disk (storage) bottlenecks. CPU and memory bottlenecks. Network bottlenecks.
