Packer – Javascript compressor
I tried 'packing' an already minimized version of JQuery (which was about 55KB) and this compressed it to about 30KB (almost 50% less). My advice - don't publish any javascript without pumping it through this first!

Some tips:
- Packer obfuscates code, so it makes things very difficult to debug. If you end up having problems with compressing the code, try compressing sections at a time to find out what's causing the problem.
- Write code so that it doesn't rely on whitespace or line-breaks. Use braces instead.
- Don't forget your semi-colons. (Especially when declaring anonymous functions for example)
Gravatars
Gravatar: Derived from 'avatar' - Globally Recognized Avatar, is basically an avatar image that follows you across the web when you comment on gravatar-enabled blogs using a unique e-mail address.
Interesting, because this would imply that anyone could use your gravatar if they knew the e-mail address you used to sign-up for the account. So if you're going to sign up for one, I'd suggest using an e-mail address not known to anyone else.
If you have a blog of your own, take a look at the full implementation guide.
If you already have a wordpress blog, the easiest is to upgrade your installation to the latest available version (Version 2.5 comes with the functionality built-in - this only means gravatars will get more popular). Blogger hasn't implemented it yet - although it should only be a matter of time before they do.
You might have to do some tweaking if you developed your own wordpress theme:
The syntax is:
function get_avatar( $id_or_email, $size = '64',$default = 'http://url-to-default-avatar' )
This example uses the user's e-mail address to retrieve the gravatar at 80x80 pixels (add to comments.php):
<?php echo get_avatar( get_comment_author_email(), '80' ); ?>;
