As of PHP 5, you can easily modify array’s elements by preceding $value with &. This will assign reference instead of copying the value.

<?php $arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
$value = $value * 2;
}
// $arr is now array( 2, 4, 6, 8 )
unset($value); // break the reference with the last element
?>

James is a Traffic Management Coordinator at the Philadelphia International Airport Control Tower. He said:

My job is to reduce departure delays and to maintain an efficient flow of air traffic into and out of the Philadelphia International Airport. Currently we utilize a Google Spreadsheet to share real-time departure and weather issues, airport construction updates, and snow removal operations with the airlines and other interested parties. Im excited at the prospect of being able to embed real-time weather radar gadgets to provide users an up-to-the-minute graphical look at the weather. We currently use the chat feature on Google Spreadsheets but it appears that the more robust communication capabilities in Wave would greatly enhance our communication with the airlines. The ability to review conversations and data will help us to further reduce delays at Philadelphia International Airport. This will result in a savings of time for passengers, reduced fuel and operating costs for the airlines, and fewer complaints from both.

All I can say is: wow.  ATC on Google Apps? Nice.

SELECT * FROM orderspecs ORDER BY height, depth, width;

Now what if you want the columns to have different sort orders in the sub-sorted columns? No problem. Just specify the order for each column.

SELECT * FROM orderspecs ORDER BY height DESC, depth ASC, width DESC;

document.getElementById('test').class = "test"

“class” is a reserved name, of course… So you access it with:

document.getElementById('test').className = "test"

## Fix Backspace/Delete confusion problem.
set rebinddelete

That fixed the issue.
