WordPress and jQuery issues

First, I don’t remember where I found this along the way, but this is a smart and efficient way to include jQuery in your WordPress themes. Just add this to your theme’s functions.php file:

add_action( ‘init’, ‘jquery_register’ );
add_filter( ‘script_loader_src’, ‘jquery_unversion’ );

function jquery_register() {

if ( !is_admin() ) {
wp_deregister_script( ‘jquery’ );
wp_register_script( ‘jquery’, ( ‘’ ), false, ‘1.x’, false );
wp_enqueue_script( ‘jquery’ );

// remove version tag to improve cache compatibility
function jquery_unversion( $src ) {

if( strpos( $src, ‘’ ) )
$src = remove_query_arg( ‘ver’, $src );

return $src;

Now, the issue I have been having is that when I try to add your own jQuery scripts or functions in your theme’s header.php file, I always get this error:

“$ is not a function”

What?  Yes it is, dammit!

Turns out WordPress has reserved the $ character, so you have to rename all occurence of $ to ‘jQuery’.  Example:


<script type=”text/javascript”>
$(document).ready(function() {
fx: ‘fade’,
timeout: 4000,
speed: 2000


<script type=”text/javascript”>
jQuery(document).ready(function() {
fx: ‘fade’,
timeout: 4000,
speed: 2000

Hope that saves someone the hours of frustration I have had with this.

Can’t Install Firebug in Firefox

I ran into this problem where I was unable to install Firebug in Firefox. It would act like it was installing, Firefox would restart, but the plugin was simply not there.

A little research revealed there could be a variety of reasons for this, but for me it turned out Avast! antivirus was preventing it from working.

I disabled the Network service in Avast! long enough to try again, and it all worked.

Hopefully this will help someone else who runs into the problem.

Redirecting root’s Email on Red Hat

red-hat-logo-bigIf you are a conscientious system administrator, you like to keep tabs on your server by checking root’s email at least once a day, correct?  If you manage more than one server, or get tired of having to log in to check your mail, you can redirect where email for the root user gets sent.

I ran into problems on Red Hat Enterprise 5.2 doing this, so I thought I’d post the resolution here.

Configure Putty Settings For Improved Performance

Not sure about you, but I use Putty perhaps more than any other application on my Windows PC’s.  Putty is a powerful, fast, free application which can be used to connect you quickly and securely to your Linux/Unix environment.

A person named “dag” from the Field Commander Wieers blog has provided an excellent article on configuring Putty for optimal usability and performance called “Improving Putty Settings on Windows“.  After walking through the steps listed in the article, I fired up Putty and was amazed by the improved text rendering, colors, and more.

A brief summary of settings gleaned from the article:
