Unfortunately, the WordPress online documentation is a mess of old, outdated API information and when I tried to make a little plugin today and have it put a little meta box in the sidebar of the edit/new post admin pages, I had one hell of a hard time getting things to work the way it was documented.
Everywhere I looked, it told me to hook on to the “admin_menu” event when I wanted to queue up my meta box using add_meta_box(). After a bit of messing around, it seemed as though I had it working for the edit post page, but then it wasn’t showing up on the add new post page. I did a bit of debugging and ensured that it was the fact that the add_meta_box() call wasn’t being queued properly – I assume it had something to do with when it was being added to the meta box queue… ultimately meaning that the “admin_menu” event was too early of an event for me to hook on to.

This is just a small nerd post for those of you who may be trying to use the beta 3.0 series of EasyPayPal for WordPress. The script has a very common bug in it that shows up if you don’t configure any categories to be hidden unless purchased in the options. The fix is very simple and I’m rather amazed it hasn’t been committed yet. All that has to be done is to initialize the $cats variable to an empty array since the variable is only created inside a conditional (bad coding!).

I just finished spending a few hours messing with this flickr junk which everyone seems to put on their sites (which means I’m not cool unless I have it too!). It wouldn’t have been so bad but at first I didn’t even know that you could create a flickr badge – then it took me even longer to figure out where on flickr’s site I could go to get info on making one 
Anyways, right now I’m trying out this flickrRSS plugin which isn’t bad, but honestly doesn’t do anything spectacular, and it’s not as feature rich as using a flickr badge (though it doesn’t put a requirement of JavaScript on the client which is nice). I would prefer to use the flickr badge for now, but the default WordPress theme I’m using is horribly written (though I will say it looks rather nice – but the HTML/CSS coding causes all sorts of problems when you try to add to it) to be honest and was pissing me off as I was trying to display images as floated block elements, though this caused the rest of the sidenav to flow as if the entire image div was a floated inline block. Of course clearing all floats doesn’t work since the entire sidenav is floated itself (argh!).
