A shell is a command interpreter which allows the user to interact with the computer. The way things work is simple: the user types in commands, the shell interprets them and performs the tasks it was asked to do, and finally it sends the result to the standard output (which is usually the screen). For example, the output of the ls command can be something like:

Back in November Intel had formally launched the Core i7 series, but Linux benchmarks were not to be found. However, in the weeks that followed, results began to emerge through the Phoronix Test Suite and Phoronix Global. Over time there were many more Linux test results from the Phoronix Test Suite community, but now we have posted some of our own Intel Core i7 numbers from Ubuntu Linux.

With Ubuntu 9.04, otherwise known as the Jaunty Jackalope, set to be released in less than three weeks, WorksWithU will be publishing some posts about what the latest and greatest version of Ubuntu will mean to different groups of users.

This tutorial shows how to prepare an Ubuntu 8.10 server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.

Well no matter what you try sometimes things break and inevitably when they do it happens at 3am just as your nodding off. Well in case you were not aware Nagios has a wonderful feature called event handlers. I have a great network I really do but its got a lot of crappy services on it for example CPanel and IIS servers. IIS has a great habit of dying and when it does all it requires is a restart to get it going again on the side of this we also happen to use Cygwin SSHd on our Windows servers, so in this article I am going to focus on getting Nagios to restart IIS for us to get it back to normal. To do this you will obviously need a server running Nagios and one running IIS on Windows with Cygwin SSHd installed.

Wordpress is the most widely used content management system amongst bloggers for many reasons. Not only does it make site management seem like a walk in the park, but it also uses a type of shared hosting, which means that most users can afford it. It has plug-ins for any occasion and desire and finally, it has themes. For many Wordpress users, finding the right theme is a long process that often leads to endless tweaking in the code and stylesheets. However, only a few ever consider learning how to create their own. If you are one of them, this tutorial will help you learn how to built and start your own theme.

Quick: Name the biggest reseller of Red Hat Enterprise Linux. The answer very likely is Dell. Now, the PC giant is striving to become the largest reseller of Red Hat’s JBoss open source middleware. Here’s how.

Sometimes, you have to respect someone for sticking to an opinion and a vision. Other times, you have to wonder if a consistent vision becomes a fatal flaw. I’m still undecided about whether Red Hat CEO Jim Whitehurst has the correct — or flawed — long term vision for desktop Linux. Here's why.

The Mandriva development team this morning made available the second release candidate for its Linux 2009 Spring release. Codenamed Estephe, RC2 includes a number of desktop enhancements including KDE 4.2.2, Gnome 2.26. kernel 2.6.29 and X.org server 1.6.

It’s not outright praise, but Dell testers call Windows 7 beta code “promising.” The VAR Guy values Dell’s opinion because the PC giant had the nerve — and the confidence — to ship Ubuntu Linux on selected PCs the year Microsoft launched Windows Vista. Fast forward to the present, and here’s what Dell has to say about Windows 7.

Zend Technologies has built an application server for PHP that it hopes can slowly convert frustrated Java programmers as well as those relying on Java on the web and in the enterprise. On Tuesday, the company is expected to unveil the Zend Server, a paid-for PHP stack that comes with service agreements and support and the free Zend Server Community Edition.

The next step for Sun Microsystems Inc., after its apparent failure to reach an agreement with IBM on an acquisition, is to continue looking for a buyer, change its management — or just keep plugging along and pretend that nothing ever happened. In terms of a sale, it's entirely possible that Sun could attract bids from Cisco Systems Inc., which is trying to move into the server business, or Fujitsu Ltd., which makes servers based on Sun's Sparc technology, or even Hewlett-Packard Co., as part of its perpetual market-share battle with IBM.

CentOS 5.3 now comes with disk encryption. When you install the operating system you have the option to encrypt block devices, partitions that you create. Block device encryption requires a passphrase or key as authentication in order to access the data on that partition. The advantage of block encryption is that it will enforce the encryption even if the disk is removed from the operating system.

NVIDIA had ended out March with five Linux display driver releases with it ranging from a day to a week between updated Linux drivers were pushed out from this Santa Clara company. It's been just over a week since their last display driver release, but it looks like April will be another month of fierce Linux/Solaris/BSD driver updates from NVIDIA.

This afternoon NVIDIA has pushed out the 185.19 Beta driver...

In this tutorial, we fill in the step-by-step details required to get a functioning Zenoss system. We identify dependencies, review installation options, and take a look at server setup.

Relational databases define a strict structure and provide a rigid way to maintain data for a software application. Apache's open source CouchDB offers a new method of storing data, in what is referred to as a schema-free document-oriented database model. Instead of the highly structured data storage of a relational model, CouchDB stores data in a semi-structured fashion, using a JavaScript-based view model for generating structured aggregation and report results from these semi-structured documents. CouchDB has been developed from the ground up with Web applications as the primary focus and has its sights on becoming the de-facto database for Web application development.

I was lately impressed by Marble Desktop Globe, a free, open-source application for KDE4 which includes a 3D atlas of the world, with lots of features and an interface similar to the one of Google Earth.
