$ git push origin :remoteBranchName

So if for example your remote branch is called “testBranch” and the remote is called “origin”, you would run:

$ git push origin :testBranch

Some people refer to it as the grown up version of Facebook and I have to say I agree completely. Google has done a magnificent job in addressing the faults and limitations of Facebook. Have a look at the following videos to find out all you need to know about Google+ enjoy!

You simply need two files:
1. .htaccess
2. .htpasswd

The .htpasswd file contains the login details (username:encryted password) of the users allowed to enter the area of the site you are protecting. This ideally should be placed outside of the web root so it is inaccessible to the world.

The .htaccess file needs to be placed in the folder you wish to protect. Basically if someone tried to access any file below the folder location of the .htaccess file, they would be prompted to enter login details. The contents of this file states that authorisation is required and also points to the location of the .passwd file so that the entered login details can be checked against.

There is a great and easy to use tool on Dynamic Drive to help you generate these two files.

As a web developer, a great use for this is to password protect your client site until it is ready to go live.  This allows the search engines to only start crawling the site once the site is goes live.

Requests

You need to reduce the number of requests.  The more requests, the longer the page load.  Every time you define an external javascript or CSS file, well that’s an additional request each time.  If you have multiple CSS files, try combining them into one file.  The same goes for your javascript files.

Images

You need to optimise your images.  In most cases you can drastically reduce the filesize of your images without losing quality (un-noticeable to the naked eye anyway).  If you use Photoshop, make use of the “save for web” option.  You can also use  Smush.it which is an online tool for reducing filesizes without reducing quality.

Compress your CSS and JavaScript

Larger CSS and JS files equals longer page load time.  So, once you’re happy with your CSS and JavaScript files, it’s good practice to use a compression tool that will compress and drastically reduce their filesizes.  Some handy compression tools are YUI Compressor and JSMin.

Online tools:

• YUI Compressor tool – http://refresh-sf.com/yui/
• JSMin tool – http://jscompress.com/
• The JavaScript CompressorRater – http://compressorrater.thruhere.net/

Sprites

As said earlier, the more requests, the longer the page load.  The same goes for images.  A trick is to combine several images on your page into a single image (a sprite).  If for example you have 5 images for your main menu items, all this can all be combined into a single image thus reducing the number of requests from 5 to 1.  All you do next is apply some CSS magic to control what is shown for each menu item.  Voila!  Project Fondue is an awesome site where you simply upload your individual images and it will generate a sprite image aswell as all the CSS.  How easy is that!

Wrap up!

These are the main tricks you can apply, if you want to read up more, there is a comprehensive article on the Yahoo Developer Network. Mark Stanton also did an excellent presentation at the 2009 Web Directions South conference on this topic. View Mark Stanton’s presentation slides.

I hope this helps you out!

A valid GUID is in the form of xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (8-4-4-4-12).

<cffunction name="isGUID" access="public" returntype="boolean" output="false" hint="returns true if is a valid GUID.">
<cfargument name="str" required="true" type="string">

<!---
Returns true for a valid GUID (a UUID in the Microsoft form).
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (8-4-4-4-12)

@return Returns a boolean.

<cfreturn  REFindNoCase("^[0-9A-F]{8}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{12}$", arguments.str) />
</cffunction>

You can do it the long way by looping over the arrays or even better, you can use this simple ColdFusion function I have put together.

<cffunction name=”arrayMerge” access=”public” returntype=”array” output=”false” hint=”Appends array2 to array1 and returns merged array”>
<cfargument name=”array1″ required=”true” type=”array”>
<cfargument name=”array2″ required=”true” type=”array”>

<cfset var a1 = arguments.array1>
<cfset a1.addAll(arguments.array2)>

<cfreturn a1 />
</cffunction>

<style type="text/css">

.opaque {
opacity: .5;
filter: alpha(opacity=50);
}
</style>

In the body, simply apply this class to any div you would like to have the opacity

<div class="opacity"></div>
