It's a very common problem in shared web hosts, check it out and optimize your website by implementing it!
Most of the shared web hosts that allow hosting of multiple sites from a single hosting account (like Hostmonster, Hostgator etc.) has a common structure. You'll have one main website or domain and all the other websites or domains will be added as Addon domains from cpanel. This way you can host multiple websites from a single hosting account. However, this approach has a problem. With each Addon domain created from cpanel, you also automatically get a subdomain (almost in all cases). Now, the challenge is to using the Addon domain, without the auto created subdomain. This may be important for your website optimization.Since, most of the times, they enable this Addon domain option in cpanel, by creating a subdomain of the main site and then pointing that subdomain to the newly created Addon domain. So in a way, the Addon domain is joined together with the subdomain, and doesn't work without it.

It may have baffled you, since even though no one earns anything, everyone's debt is paid for. Well, there is no trick, so let's just demystify the puzzling story once and for all.

One day a tourist comes to the only hotel in a debt ridden town in Kenya. He lays a 100 dollar note on the table & goes to inspect the rooms.
Hotel owner takes the note & rushes to pay his debt to the butcher. Butcher runs to pay the Pig Farmer. Pig Farmer runs to pay the Feed Supplier. Supplier runs to pay the Prostitute, who in these hard times gave her services on credit. Prostitute then runs to pay off her debt to the Hotel Owner for the rooms she rented for her clients.
Hotel Owner then lays the 100 dollar note back on the counter. The tourist comes down, takes his money & leaves as he did not like the rooms.
No one earned anything. But the town is now without debt & looks to the future with a lot of optimism.
And that is how the world is doing business today!

Learn how to handle PHP and MySQL date formatting correctly.
If you ever try to format date in PHP and MySQL, using date (datetime or timestamp) value directly from MySQL to PHP date() function, then you'll get a Notice level error, something like this:
Notice: A non well formed numeric value encountered in ... .. .
Additionally, PHP date() will always return January, 01 1970 if MySQL date is directly used. It means, there is a difference between date in PHP and date in MySQL (i.e. they are not compatible).

A new form of Spam | Trojan | Virus, posing as Flash or other plugin installer - originated from Facebook Friend Feed. It posts spam on your and your friends' wall and also have the ability to affect your computer.
People, there is a new attack site or link (originated from Facebook) with the following pattern (emphasize on point 3 below, posing as Flash or other Plugin installer):
- It is posted on your friend feed because one or more of your friend's PC was attacked. (BTW, it may appear on your wall, even if you didn't click - in case the compromised friend of yours has the access to post on your wall. This normally happens through tagging. When the virus posts on your friend's wall, it may also tag you. So it will appear on your wall too. So if you fear that one or some of your friends FB account is compromised, then temporarily disallow him/them to post on your wall from Facebook privacy setting)

- You are logged in or not, in either case, it will try to play a video after that, and after a few seconds, it will say
"Plug-in not installed, click to install plugin" - or something similar.
It looks something similar, when your browser doesn't have Flash player installed.
