Technically, there is nothing special about showing code on a WordPress site. You just wrap code in <pre></pre> (and probably , for semantics and font control) tags, something like this:

WordPress ships with its own version of the jQuery library (for longevity’s sake, as I write this WordPress is at version 3.2.1).

So to use jQuery in your WordPress plugins and themes “The Right Way” all you need to do is enqueue the script (probably via your theme’s functions.php file). Here is a basic example:

Here’s the really short version:

I used /%postname%/ as my permalink structure on CSS-Tricks for a long time. I have lots of Pages. My site went down. I changed my permalink structure to begin with a number. Now it’s fine.

Tiny little fun idea by Dave Rupert.

One of my other sites, CSS-Tricks, has been around a number of years now. There are nearly 1,400 unique pages of content almost all of which have a comment thread. I had a feeling that in the last four years, despite fairly steady growth in traffic and subscribers, that the number of comments per post has dropped. But how to prove it? I don’t know of a way to easily see that data.

Digging into WordPress is an entirely self-published book. It’s not that way because we just arbitrarily decided that self publishing was hip and that was what we were going to do. In fact, the plan early on was the opposite. Step one, we thought, was to write the book. So we did that. Then step two became find publisher to publish it, so we asked around. We talked to five (or so) tech book publishers.

I posted a little tip on CSS-Tricks the other day about how you can load only parts of other pages on a site via Ajax, and how to do that without needing additional HTML wrapping elements to keep it clean. A common criticism of this is that the Ajax request still loads the entire page, using all that bandwidth, it’s just that it only places onto the page the part you specify via CSS selector.

Sometimes it’s hard to have discussions like this without looking at specific use case, but I see where they are coming from. Loading content you aren’t going to use is a waste of bandwidth. It does make progressive Ajax enhancements a lot easier though. And in fact, that’s how our All AJAX theme works.

The default URL for logging into your WordPress powered site is: http://example.com/wp-login.php. Or if you’ve installed in a subdirectory, something like http://example.com/wp/wp-login.php. I’ve wished that was a little cleaner, especially when you are doing something explaining to a client where to log in over the phone. Fortunately changing this can be very easy.
