Google may be the 8000 pound gorilla of website marketing, and Google search results may be 80% of your traffic, and if you run Adsense advertising they may be paying most of your income, and if all that is true it makes you very dependent on Google's whims. That's the message of: Why You Should Forget About Google And Start To Diversify Your Traffic Sources Only by diversifying ones traffic sources will one be immune to whimsical changes in Google policies.
Digital cameras by their nature should be infinitely flexible. But the camera makers sell them with a given set of features. What if you want other capabilities? If the digital camera makers were the sole determiners we'd be stuck with the features they design into the cameras. Fortunately many people have worked out ways to change the capabilities of digital cameras.
The Apache web server offers a feature called "virtual hosting". What this does is make one computer be a server for more than one domain. This is a widely used way to share multiple websites on one server. For example when a web hosting company offers shared hosting, they are using virtual hosting to make it so each of their servers houses more than one of their customers.
Mac OS X does not include MySQL or any other SQL server. Since a database is such a crucial part of web site construction, let's look at how to set this up.
Getting the server
Macintosh, Apache, Mysql and PHP (MAMP) offers a convenient package that you download as a DMG and it executes an Apache/MySQL/PHP instance. It is meant for development, not for running a production web server.
The MAMP stands for: Macintosh, Apache, Mysql and PHP. With just a few mouse-clicks, you can install Apache, PHP and MySQL for Mac OS X! And, it really works. However it is absolutely not for general production use. Instead MAMP is configured explicitly for development use.
Mac OS X comes with a PHP interpreter built into the system. It is relatively easy to enable this so you can do PHP development.
First, make sure that "Web Sharing" is turned off.
Second, edit the file /etc/httpd/httpd.conf.
Third, search through that file for lines containing the string "php". You'll find two that are important, and that they commented out by having a '#' character at the beginning of the line. Remove the '#' character. The two lines are:
Mac OS X is Unix with a pretty face. That means most of the things available for Linux systems are also available for Mac's. Most of the tools, practices, etc transfer pretty easily. Since most web hosting providers use Linux systems, this makes Apple's Mac a great choice for prototyping web sites, especially as Apple includes a web server bundled with the system.
Unfortunately Apple did not include enough for this to be a great prototyping system.
