Install Apache

To start off we will install Apache.

1. Open up the Terminal (Applications > Accessories > Terminal).

2. Copy/Paste the following line of code into Terminal and then press enter:

sudo apt-get install apache2

3. The Terminal will then ask you for you’re password, type it and then press enter.

Testing Apache

To make sure everything installed correctly we will now test Apache to ensure it is working properly.

1. Open up any web browser and then enter the following into the web address:

http://localhost/

You should see a folder entitled apache2-default/. Open it and you will see a message saying “It works!” , congrats to you!

Install PHP

In this part we will install PHP 5.

Step 1. Again open up the Terminal (Applications > Accessories > Terminal).

Step 2. Copy/Paste the following line into Terminal and press enter:

sudo apt-get install php5 libapache2-mod-php5

Step 3. In order for PHP to work and be compatible with Apache we must restart it. Type the following code in Terminal to do this:

sudo /etc/init.d/apache2 restart

Test PHP

To ensure there are no issues with PHP let’s give it a quick test run.

Step 1. In the terminal copy/paste the following line:

sudo gedit /var/www/testphp.php

This will open up a file called phptest.php.

Step 2. Copy/Paste this line into the phptest file:

<?php phpinfo(); ?>

Step 3. Save and close the file.

Step 4. Now open you’re web browser and type the following into the web address:

http://localhost/testphp.php

Congrats you have now installed both Apache and PHP!

Install MySQL

To finish this guide up we will install MySQL. (Note – Out of Apache and PHP, MySQL is the most difficult to set up. I will provide some great resources for anyone having trouble at the end of this guide.)

Step 1. Once again open up the amazing Terminal and then copy/paste this line:

sudo apt-get install mysql-server

Step 2 (optional). In order for other computers on your network to view the server you have created, you must first edit the “Bind Address”. Begin by opening up Terminal to edit the my.cnf file.

gksudo gedit /etc/mysql/my.cnf

Change the line

bind-address = 127.0.0.1

And change the 127.0.0.1 to your IP address.

Step 3. We are now going to install a program called phpMyAdmin which is an easy tool to edit your databases. Copy/paste the following line into Terminal:

sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin

Step 4. Now linking phpMyAdmin to Apache’s www folder

sudo ln -s /usr/share/phpmyadmin /var/www/phpmyadmin

After that is installed our next task is to get PHP to work with MySQL. To do this we will need to open a file entitled php.ini. To open it type the following:

gksudo gedit /etc/php5/apache2/php.ini

Now we are going to have to uncomment the following line by taking out the semicolon (;).

Change this line:

;extension=mysql.so

To look like this:

extension=mysql.so

Now just restart Apache and you are all set!

sudo /etc/init.d/apache2 restart

Remove the old version of GIMP from Synaptic or in a terminal:

sudo apt-get remove gimp

Download and save all five GIMP packages from GetDeb. Double-click on the packages to install them, in this order:

1. libbabl-0.0-0_0.0.22-1~getdeb1_i386.deb
2. libgegl-0.0-0_0.0.18-1~getdeb1_i386.deb
3. libgimp2.0_2.6.1-1~getdeb1_i386.deb
4. gimp-data_2.6.1-1~getdeb1_all.deb
5. gimp_2.6.1-1~getdeb1_i386.deb

Now you can start GIMP normally, from Applications->Graphics->GIMP Image Editor.

The CSS method uses what is known as an image sprite to load all the rollover effects as a single image and we then use CSS to do the transition. To create the image sprite just create a single image containing all of the individual transitions.  Once you have your image sprite you just need the HTML and CSS code:

CSS Code:
a.grnBTN {
display: block;
width: 200px;
height: 45px;
text-decoration: none;
background: url(“greenBTN.png”);
background-position: 200px;
}

a.grnBTN:hover {
background-position: 0 0;
}

.displace {
position: absolute;
left: -5000px;
}

HTML Code:

<a href="#" class="grnBTN" title="Image Title">
<span class="displace">Alternative Text</span>
</a>

• The width and height values in a.rollover are the size of the original image.
• The value of background-position is that of the original image width since we are literally moving from one part of the image sprite to another.
• The <span> tag was included with a text alternative to the image and displaced it off the side of the visible screen so that screen readers will read it and in the event of no CSS support a text link will be shown instead.

In order for your code to directly handle an exception, the tags in question must appear within a cftry block. It is a good idea to enclose an entire application page in a cftry block. You then follow the cftry block with cfcatch blocks, which respond to potential errors. When an exception occurs within the cftry block, processing is thrown to the cfcatch block for that type of exception.

Here is an outline for using cftry and cfcatch to handle errors:

<cftry>
   Put your application code here ...
   <cfcatch type="exception type1">

      Add exception processing code here ...
   </cfcatch>
   <cfcatch type="exception type2">
      Add exception processing code here ...
   </cfcatch>

   ...
   <cfcatch type="Any">
      Add exception processing code appropriate for all other exceptions
here ...
   </cfcatch>
</cftry>

Are you a web developer like myself needing to test crossplatform and would really prefer do it all on 1 OS (not Windows) well I have the solution IEs4Linux

Type this in a Linux command terminal:
===================================================================
wget http://www.tatanka.com.br/ies4linux/downloads/ies4linux-latest.tar.gz
tar zxvf ies4linux-latest.tar.gz
cd ies4linux-*
./ies4linux

===================================================================

Prerequisites:

· Your BIOS must support booting to an USB device, and that functionality has to been enabled

        · An empty 4GB (or greater) USB device, and you’ve removed all other important files from the device. This process will WIPE IT CLEAN. You have been warned.

        · You must be using Windows Vista (or newer) DISKPART

Note: Don’t insert the USB device just yet. I’ll will tell you when.

Open a command prompt as administrator. From the C:> prompt, type:

diskpart

From the DISKPART> prompt, type:

list disk

Make mental note of the disks you have. Then, insert your USB device, and

list disk

again. You should see a new disk with a new number. That’s the number you’ll use in the next command:

select disk x

(x = the number for your USB device)

To make sure that there’s nothing on the USB device that will interfere with our booting; we will wipe out any and all partition information on the device. WARNING! This will wipe the USB device clean! It will delete and destroy any and all data on the device.

From the DISKPART> prompt, type:

clean

Now we want to create our primary partition for booting. From the DISKPART> prompt type:

create partition primary

Now we want to change to that partition and make it an active or bootable partition. From the DISKPART> prompt type:

select partition 1

When that step completes, type:

active

Next we need to format our active partition and assign a drive letter to the boot partition.

From the DISKPART> prompt type:

format fs=fat32 quick

When the format completes, type:

assign

You can now exit DISKPART and close the command prompt.

The USB device is now ready to boot. Next, just copy the files from the ISO (if you’ve mounted it using a tool which does this) or from the Windows 7 DVD onto the USB device.
