Performing / Managing Background Jobs in Linux
To perform processes in the background in Linux, use the command
screen (instead of the session-tied-up

Screens are terminal sessions which can be detached (placed in the background) and reattached (placed in the foreground). When detached, these screens still run and can be brought back again for use in future connections.
Command list:
screen -list
Displays all the running screens and their socknames
screen -S
Creates a new screen with as the name instead of a generated one
screen -r
Reattaches a detached screen
When a screen is attached, you can either use..
Ctrl+A then Ctrl+D to detach the current screen, or
Ctrl+D to terminal the screen.

I had trouble persisting session data between two transitioning pages in an iframe in IE (7+ i think). The page in the iframe and the parent page (containing the iframe) are in two different domains.

header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');

Bug: Zend Framework 1.5.1-1.5.3 Zend_Rest_Client
When contacting the Rest Server via the Zend_Rest_Client's get() method, you will get errors when passing a string argument that's roughly 500+ characters long.
The code:$client = new Zend_Rest_Client($restServer);// $arg1 has 1000 length$result = $client->MyMethod($arg1, $arg2)->get();would yield:string '
Invalid Method Call to MyMethod. Requires 2, 1 given.
failed' (length=242)
You can get the data sent back from contacting the rest server by dumping the variable $data before line 43 in
Zend/Rest/Client/Result.php (ZF 1.5.3):
var_dump($data);Fix:Use the method
post() instead of get().
