The computer programming language ADA was named in honor of Augusta Ada King. The U.S. Defense Department named the language after the Countess of Lovelace and daughter of Lord Byron because she helped finance and program what is thought to be the first computer, the “analytical engine” designed by Charles Babbage.

Sample PHP code for creating forgot password feature in any website

Find below the sample php code which can be used for implementing the forgot password feature.

$email_to=$_POST['email'];

if ($email_to == "") // Email address cannot be empty
{
  header("Location: mail-password.php?send=Email not entered");
}
else
{
      if(is_valid_email($email_to)) // check the valid email address or not
              {
              $to=$email_to;
              $subject="QualityPoint Password"; // Your subject
              // From
              $header = 'From: info@qualitypointtech.net' . "\r\n" .
              'Reply-To: info@qualitypointtech.net' . "\r\n" .
              'X-Mailer: PHP/' . phpversion();
            //add code for selecting $userid and $pass for user table for the input $email_to.
              // Your message
              $messages.="Forgot password - qualitypointtech.net  \r\n";
              $messages.="-------------------------------------- \r\n";
              $messages.= "Your login information to our website is- \r\n";
              $messages.="UserId: $userid \r\n";
              $messages.="Password: $pass \r\n";
              $messages.="-------------------------------------- \r\n";
           
              // send email
              $sentmail = mail($to,$subject,$messages,$header);
           
              if($sentmail) //if your email succesfully sent
              {
                  header("Location: mail-password.php?send=Password has been sent to your email id");
              }
              else // Cannot send password to your e-mail address
              {
                  header("Location: mail-password.php?send=Not able to send email");
              }
      }
   
      else //Email address has not been found in our database
      {
          header("Location: mail-password.php?send=Email address not found");
      }
}


function is_valid_email( $address )
{
  $rx = "^[a-z0-9\\_\\.\\-]+\\@[a-z0-9\\-]+\\.[a-z0-9\\_\\.\\-]+\\.?[a-z]{1,4}$";
  return (preg_match("~".$rx."~i", $address));
}

The step involved are,
1. First provide a form with input text box with name "email" for allowing the user to enter his email id.

2. On submitting this form, the "email" will be posted to the php page mail-password.php.

3. From user table, query the password corresponding to the entered email id. (If you have stored the password in encrypted form then reset it with default/random password and send this default/random password to the user)

4. Validate the email id.

5. Prepare the email message and send it using php mail() function.

Virtualization

Virtualization:

Virtualization is extending the computer so that it can run multiple os. For eg: We can run Linux on our Windows machine.

Uses of Virtualization:

one can run software written for one operating system on another(Even if the the real computer hardware is no longer supported by the virtual os)

After installation the virtual box is act as container, we can copy transport and back up between hosts.


One can save a particualr state and revert back.

It reduce the hardware and electricity costs.

Currently,Sun VirtualBox runs on the following host operating systems:


Windows hosts:

Windows XP, all service packs (32-bit)
Windows Server 2003 (32-bit)
Windows Vista (32-bit and 64-bit[1]).
Windows Server 2008 (32-bit and 64-bit)
Windows 7 (32-bit and 64-bit)

Mac OS X hosts:[2]

10.5 (Leopard, 32-bit)
10.6 (Snow Leopard, 32-bit and 64-bit)


Linux hosts (32-bit and 64-bit[3]). Among others, this includes:

Debian GNU/Linux 3.1 ("sarge"), 4.0 ("etch") and 5.0 ("lenny")
Fedora Core 4 to 11
Gentoo Linux
Redhat Enterprise Linux 4 and 5

Google makes changes small-and-often. They will sometimes trial a particular feature with a set of users from a given network subnet; for example Excite@Home users often get to see new features. They aren’t told of this, just presented with the new UI and observed how they use it.
