Linux: The 007 of Servers and Hosts
You are on a mission. You have your cool shades on to obscure your gaze of determination from anyone who may try to deviate you. Your domain name has been purchased, you have the conceptual mapping of your website planted firmly in the corner of your mind. But before you even consider building your website, you need your best James Bond gadgets in place. You need dual engines to power and support the product of your passion. Before construction of your website can begin, you need a server and a host. i.e. a virtual Miss Moneypenny to charge your operation and converse within it. Much like James Bond, they must be sleek, stealthy, robust, and function at the highest level with minimum ease.
Web hosting systems are, basically, as varied as the sides of a coin: you have two main choices, Windows or Linux. Making this selection can be an overwhelming endeavor. Continue to read on, and together lets explore the endless possibilities that go hand-in-hand with Linux hosting and servers. Lets compare one nemesis to another.
Linux vs. Windows in A Game of Wits and Common Sense
So which one is better? Linux Is highly regarded as being advantageous for several reasons: Every one of its hosting varieties is equipped with options to enable users the absolute best in their hosting endeavors. Talk about customizing your weapon of choice!
Cost vs Quality
Not only is Linux a free source BUT it lets you modify the functionality to be used in nearly every imagined application (Windows hosting is not free). So how does this work and what are some popular tools for tweaking the system to the users specific needs? (keep reading, we are about to go undercover).
Some Hosting Varieties
CentOSis arguably the most popular Linux hosting platform. It has a large metropolis of users and ranks at the top in customer satisfaction for performance. The software is free, and it puts the user within an online populace dedicated to working together to achieve their goals and deal with any issues. Sounds a bit Communist, right? Fear not, there are no Stalin JPEGS that pop up! Another way of looking at CentOS is that it provides a springboard for formulating ideas and questions that will help strengthen the platform and ultimately provide the best in service for all users.
Linux hosting provides an arsenal of weapons to polish the customized hosting source, such as FreeBSD. To incorporate the FreeBSD ports, the most popular Linux distribution is Bendoo, and can be easily blended to your customized hosting platform. This will assist in the installation of additional applications, while automatically updating. However, features in older versions may no longer be supported by the upgrades. But fear not, for the user-friendly patches embedded in the system permit users to make the original application source code compile and run off FreeBSD. Installation is simple, and precompiled packages are also an option, which saves the user a ton of time in virtually eliminating the compilation process of picking and choosing.
Linux also has been anointed with a diverse scripting language support system. Whether you require Ruby on Ralis, PHP, Python or Perl, a Linux hosting platform will typically support them all by default.
Which offers the stealthier server?
As you know, a Web Host hosts your website while the server serves data to multiple machines on the network. Although servers are typically used in high-usage companies with centralized e-mail and intranet, servers are becoming more popular within home-use for large families. The host and server are meant to work in harmony, so if you decide on Linux for your host, should you also embrace it for your server? According to a server comparison by PC World, Linux destroys Windows in this battle. Lets examine the findings:
Stability
Linux servers are highly praised for their ability to run for years without failure. In fact, many users even report that they have never seen Linux crash. Windows, on the other hand, has incident after incident. Linux can also handle numerous processes running at once much better than Windows can, and this fact alone has tarnished Windows greatly.
Security
We are talking Fort Knox here! Remember that Linux was designed from the start to be a multiuser operating system, and that only the administrator has administration privileges. This means that fewer users and applications have the ability to access one another. This ensures everything is protected and modular.
Furthermore, Linux gets attacked less frequently by viruses and malware. A vast majority of these viruses were designed to work within Windows. Also, when any bug is found, it is quickly fixed by the multitude of developers and users.
Hardware
Linux is a very scalable, slim and flexible. It performs beautifully on just about any computer, regardless of the processor. Windows, however, typically requires numerous hardware upgrades to accommodate its growing resource demands. Still in love with the idea of customizing your tools? Linux can be easily reconfigured to include only the vital services for your needs. This feature alone will reduces memory requirements, improve performance, and simplify everything into a neat, clean package.
Still not convinced?
With all the advantages talked about in this article, its no surprise that governments and their branches (such as MI6), organizations, and major companies that include Amazon and Google, run off a Linux server. Also, consider that Linux is blessedly free of commercial vendors trying to lock you into certain products and practices. Instead, you are free to customize the tools and use only that which will work best for your needs.
Go out there and do your own research. You will undoubtedly, as I did, discover that Linux offers the best in serving and hosting solutions for your website. Now that you have your missions blueprint in your head, get out there! Make a loud splash, and begin the next step of having your website built. In the meantime, start with Linux Guruz and follow this link to discover 3 ways to create your web work-of-art. And remember that, once your site is up and running with a superior server and hosting platform, have that celebratory martini shaken and not stirred!

Nomad (noh'-mad) n. 1. A member of a race or tribe that
has no fixed abode but moves about from place to place. 2. A wanderer.

1.2 What is Nomad?
Nomad, a planetary-relevant mobile robot, is chartered to
traverse 200 kilometers across the Atacama Desert in Chile, exploring
a landscape analogous to the surface of the Moon and Mars.
Operating both autonomously and under the control of operators
thousands of kilometers away, Nomad and the Desert Trek address issues of
robotic configuration, communications, position estimation and navigation
in rugged, natural terrain.
The field experiment also serves as a testing ground for remote
geological investigation, paving the way for new exploration with onboard
panoramic visualization and a novel user interface, the Atacama Desert
Trek provides the general public an unforgettable interactive experience
and its first opportunity to remotely drive an exploratory robot.
An unprecedented demonstration, the Atacama Desert Trek sets a new
benchmark in high performance robotics operations relevant to terrestrial
and planetary exploration.
