What is WordPress MU?

WordPress MU, or multi-user, is designed to runn hundreds of thousands of blogs with a single install.
You can pronounciation like wordpress mu(EM-YEW) or you can aslo call “WordPress Mooooo”

Who are using WordPress MU?
•    Newspapers and magazines.
•    Big Universities
•    Blog networks
•    Niche-specific blog hosts
• uses WordPress MU!!
Features of WordPress MU.

Code which differs on wordpress mu side is that is bootstrap files, and administration for multiple blogs and users. Most of the basic code is same for both. I can say 95-99% that is amazing.
Wordpress mu can have multiple authors and you can assign different roles.

Most of the plug-in work just like in regular WordPress because basic frame of the code is same but of course not all.
But some that modify core tables or create tables of their own in the DB might have difficulties, depending on how they’re coded.

Worpress Mu can be configured on sub-domains or top level domain, just like regular wordpress.

You can enable Akismet spam protection same like your favorite one!!  But Developer of the wordpress mu prefer to go for Pro-blogger API key.

WordPress MU creates tables for each blog, which is the system we found worked best for plugin compatibility and scaling after lots of testing and trial and error. This takes advantage of existing OS-level and MySQL query caches and also makes it infinitely easier to segment user data, which is what all services that grow beyond a single box eventually have to do.
Lastly you can ask can I develop wordpress mu so the answer is pretty simple! YES because if you are familer with wordpress you will feel pretty comfortable with WordPress Mooooo!!

What is Frontpage Extension?

You would have seen term ‘Frontpage Extensions’ so many times in Cpanel do you know what is that ?

Frontpage Extensions allow you to publish your site directly from the FrontPage application. This means that you will not have to upload files through FTP, or another method.

Warning: Installing or uninstalling Frontpage Extensions will result in the loss of all “.htaccess” files in your web area. Any changes you have made to your “.htaccess” files will be lost. Any directories you have protected with WebProtect will become unprotected until you reprotect them.


Why you should use Linux?

  • Unlike many single user desktop console based operating systems, Linux is a multi-user, multi-tasking, network enabled operating system accessible from anywhere on the network.
  • Multiple users can access a Linux computer remotely, each running their own individual desktop instance, all at the same time.
  • The Linux/Unix X-Windows network enabled multi-user windowing system allows full remote access.

    This is a sharp contrast to a single user console based OS which requires the user to be physically present at the computer in order to access his desktop and applications, limiting access to one user at a time.

  • The Linux/Unix OS was designed to support remote and secure multi-user access using ssh.
  • This gives all Linux/Unix administrators and users a powerful flexible standard remote interface while the automobile is often the primary remote access tool of other OS administrators (i.e. Windows 98 and NT).
  • Linux/Unix shell scripts provide a batch scripting capability which can be scheduled, propagated to other systems.
  • Future and advanced development is ensured as the source code is available to all. It is studied in universities and institutions worldwide.
  • PhD candidates and corporate researchers use Linux to try advanced computing concepts.
  • Linux is here to stay; it is getting stronger day by day, and that is good from a technical, financial and economic point of view.

What is diffrence between echo and print?

Print method can return a true/false value. This may be helpful during a script execution of somesort. If you need to output data through a function, you can use print()

Echo does not return a value, but has been considered as a faster executed command. echo is not a function and, as such, it does not have a return value.
echo 30;
print (30);
