Clickable stack traces with Netbeans

I’m clearly in a fickle mood this month, as I’ve changed my PHP editor again, this time to Netbeans (thanks to the tireless nagging of @JJJ)… so far, so good. I particularly love being able to jump to declarations quickly and easily. One hurdle I overcame today, and I’d be interested to know if there’s …

Bees!

My grandpa always wanted to keep bees. Or at least that’s how I remember it, him talking about it and me fascinated by the idea.

Dragging, dropping and sorting, with jQuery UI

I spy a nice opportunity to document some jQuery UI functionality I’ve been playing with this afternoon, for a soon-to-be-revealed client project.
