Facebook Virus Alert! A Facebook message virus (or SPAM) is spreading fast!
Few days ago I received a private message in my Facebook inbox from a friend that looks like this:

You've probably read the story about how a tourist solves the debt problem of a small town in Kenya just by placing a $100 note on a hotel's reception counter and taking it back a while later. 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.
The story goes like this:
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!
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)
- Once you click the link, if you're logged-in on Facebook, it will post the same crap from your profile.
- 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.
- When you click this, it'll download and try to install an exe file which is actually some sort of Trojan | virus.
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). PHP date function accepts Unix Timestamp, which is different from MySQL date types (DATE, TIME, DATETIME, TIMESTAMP etc.)
If you are running a typical Blog using WordPress, then the answer is no, you shouldn't allow search engines to index your category and tag pages (if you care about maintaining a higher SEO value).
To begin Programming in PHP, almost everyone is faced with this simple but obvious question:
How to easily run PHP Program for the first time?
Answer: The easiest way to start with PHP Programming is using the software bundle named XAMPP (I'll update this post from time to time to meet the visitors' interests):
PHP programmers regularly use the functions (or more appropriately language constructs) like
require_once to insert useful codes in the flow of execution. Although these constructs are used quite interchangeably, there are actually significant differences among them. Although these differences are very well defined in PHP manual, I've noticed many programmers don't really consider these differences while coding. I hope this post will help them towards a better coding practice
How many times you've looked at a photograph and thought that if some particular junk was not there in the image, then it would be a masterpiece, or at least an excellent art work! And then, you wasted hours with your graphics editing software , only to find out that it was going to take lot more than just few hours of work. Well, watch the YouTube video below, I think the good old days are gone!
Most of the shared web-hosts that allow hosting of multiple sites from a single hosting account (like Hostmonster, CirtexHosting etc.) has a common structure. You'll have one main website or domain and all the other websites or domains will be added as Add-on domains from cpanel. This way you can host multiple websites from a single hosting account. However, this approach has a problem. With each Add-on domain created from cpanel, you also automatically get a sub-domain (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 Add-on domain option in cpanel, by creating a sub-domain of the main site and then pointing that sub-domain to the newly created Add-on domain. So in a way, the Add-on domain is joined together with the subdomain, and doesn't work without it.
Few days ago I've changed my WordPress blog hosting from CirtexHosting to HostMonster. I've used CirtexHosting for 2 years and HostMonster for more than a year, mainly for development purposes. So perhaps, within a few days, I'll post a review about their performance. In short, both of them provide very good web hosting services. However, this post is not about the review, it's about the temporary problem I've faced while shifting this blog hosting.
