Dan Popa found an interesting fix for the ever annoying flickering CSS background images in IE.
There is also a fix that involves configuring your server, which I prefer, because the new solution relies on JavaScript.
Still it’s an amazing discovery and it’s very useful in cases you don’t have access to the server configuration. I really wonder why Microsoft kept that a secret for such a long time. Maybe there are some yet unknown side effects.

As it turned out, the universal selector is a little too universal in IE 7 (RC 1).
Some simple CSS like
body * {
display: block;
border: 1px solid;
padding: .25em .5em;
background: #808080;
}
with such HTML
<body>
<p>
...
</p>
<!-- An HTML coment -->
<p>
...
</p>
</body>
results in 3 Boxes in IE 7.
Here’s my own test.
This opens the door for some new hacks and even an amazing technique to make the :before and :after pseudo-elements possible to some extend.
This technique would also make for a good clearing floats without presentational markup, as long as the clear property is applied (not tested).
Apart from that, this is not a minor issue. With such a parser bug the universal selector becomes useless or we the web developers are doomed to never use HTML comments again to be able to rely on this selector. I cannot believe that this “feature” will make it into the final release.

I contributed a cookie plugin for jQuery yesterday. You can get it from the (Subversion) repository:
svn://jquery.com/plugins
Or get it here. A few simple examples of how to use it:
$.cookie('the_cookie'); // get cookie
$.cookie('the_cookie', 'the_value'); // set cookie
$.cookie('the_cookie', 'the_value', { expires: 7 }); // set cookie with an expiration date seven days in the future
$.cookie('the_cookie', '', { expires: -1 }); // delete cookie
You’ll find the complete documentation inline.
Update
Ralf Engelschall suggested on the jQuery mailing list, that it is more intuitive to delete a cookie by passing null as value:
$.cookie('the_cookie', null); // delete cookie
I agree and updated the plugin accordingly. The old syntax for deleting still works of course.
