Websites can collect a lot of information about you just from your browsing.

Sometimes useful, sometimes unsettling, but it's interesting to know just how some of this works.

The built-in update function introduced in Joomla 2.5 is a great leap forward in simplifying Joomla version maintenance and generally works just fine [1]. Except sometimes, when you know there's a newer version available, but the update checker remains unconvinced.

We just have to provide a little encouragement and everything will be fine.

Unfortunately there isn't one.

I get a fairly regularly stream of emails and web site contact messages from search engine optimisation (SEO) people promising to improve my search results in various magical ways, but a little thought shows why this is unlikely to have any good effect.
