Joe noticed that the 'Reverse Sort' on this blog doesn't work. Sigh. Works just fine for me. It's a cookie thing. IE and Opera don't allow cookies by default these days. I guess it isn't smart to rely on them. But how else to store a user preference? Where else can you store the fact that you want a reversed blog? Requiring a login on a blog isn't very sociable. So forget a server-side database. What else is there?

URL's. Bookmarks. Encode the sort preference into the URL itself. That's all we've got left to work with. Turns out it's all I need.

Try this - macgirvin.com/blog?R

You can bookmark it and get a reverse sort on all the archive pages every time you visit. That's the bookmark version. The basic URL format is macgirvin.com/index.php?MMM-YYYYR to get a reverse sort for any specific month. But you don't need to know that. If you click 'Reverse Sort' it should just work.
