People often update their status to reflect their thoughts and feelings, or to mention things they feel like sharing. Sometimes that includes referencing friends, groups or even events they are attending — for instance, posting “Grabbing lunch with Meredith Chin” or “I’m heading to Starbucks Coffee Company — anyone want some coffee?”.

Now, when you are writing a status update and want to add a friend’s name to something you are posting, just include the “@” symbol beforehand. As you type the name of what you would like to reference, a drop-down menu will appear that allows you to choose from your list of friends and other connections, including groups, events, applications and Pages. Soon, you’ll be able to tag friends from applications as well. The “@” symbol will not be displayed in the published status update or post after you’ve added your tags.

Friends you tag in your status updates will receive a notification and a Wall post linking them to your post. They also will have the option to remove tags of themselves from your posts. We hope that tagging your status updates and others posts from the Publisher will enable you to share in a more meaningful and engaging way, and connect with even more people. We’re rolling this feature out over the course of the next few weeks, so you may not see the new feature just yet.

PHP

How to save the resource in our project code? Should we repeat writing the same code in every page/file? We can save a lot of our time and resource by putting the same code or lines into a function or procedure.

In some programming language, such as Pascal, Batch, C, PHP, etc., we can make a single special file where we can store our functions and procedure, also some constant.

Files which stored functions and procedures generally called “library“. The reason? coz it store many functions… I don’t know the other reasons..

For some constant (variables that store fixed value), we can put it on a editable file, like “config.php” in PHP or “config.tpu” in Pascal. So if we need some constant, we only need to call that file.

For example, we have some web pages that require same coding and data, but in different web design, should we write the same codes in every page? and how if there’s a minor change in the codes? it will make us work on those page again.

We can solve that problem by creating a single file that contain the function, and call the function from every page. So, if there’s any change on the code, we have to modify the file that contain the function only. In PHP, you can also include the file with “include()” function rather than calling for the function.

There a lot of free library out there, so you can use them to decrease your time in coding. For example jQuery, it is a free javascript library that store many function. There’s also Mootools, it’s has same function with jQuery.
