How to use jQuery in WordPress Themes
On a standalone (non-WordPress) project you’d import the jQuery library in the head tag, then call a jQuery function towards the bottom of your file. This approach isn’t working in WordPress. Since jQuery and many other useful libraries are already part of WordPress, there’s no need to link to your own copy. Instead, you need to “enqueue” such scripts before the closing head tag (and before wp_head() is called). This is done in your theme’s header.php file: wp_enqueue_script(“jquery”); Every...

How to disable update notifications in WordPress
Sometimes “new” doesn’t always mean “better” or “suitable”. Sometimes we require older versions of plugins and I’d rather WordPress would not tell me that there’s a newer version available. After all, I might accidentally update a plugin – or perhaps my clients do, breaking the site or overwriting customisations. Let’s take a look at how we can disable those notifications, both for single plugins and for the entire site. Disable update notifications for a single plugin You can...

I had an odd problem the other day: I wanted to restore a fairly large folder from my new AirPort TimeCapsule. But the restore always stopped at one particular file, with an error message about permission problems. The folder in question was about 4GB in size and contained just over 10.000 files in total.

I’ve just ordered a new Dynamic Cloud Server with 1&1 with a total of 800GB disk space. They rock, but they come with a minor inconvenience: due to the way these server instances are allocated, 1&1 do not automatically extend the partition for you – so you can’t actually start using the full amount you’ve ordered. Here’s how to make use of the full disk space on a current file system: df -h shows all partitions we want to grow, in my case /var is mounted on /dev/mapper/vg00-var so that’s the one I want to grow pvs shows us how much...
