Since I'm using WordPress.com Stats, I would like to use the rankings generated by this service or plugin. Searching Google, I found some widget called "WordPress.com Stats: Top Posts Widget" which works out of the box (if like to use a widget). In my case I have a custom sidebar with different custom sections using custom code. The following example explains how-to use that code on your website.

WordPress, by default, doesn't track any statistic information about the posts on your site, so you'll need something like the WordPress Stats plugin to get that part working. Once that's there, you can use his code to pull out the posts from the last few days (configurable) and show the most popular of the list.

TechCrunch, FeedBurner, iStockPhoto, YouSendIt, Meebo, Vimeo and Alexaholic. These are some of the most popular websites on the Internet. You have heard about them, you have read about them and you have most likely used or visited at least one of them. But how often have you read about what these websites are actually running on? This article dives into the facts and figures about the underlying hardware and software that keep these sites running smoothly in spite of their massive popularity.

As mentioned, there's no real surprises in the list - Linux still tops out on the server popularity, Apache and MySQL dominate their fields and, according to the numbers, PHP is still on top in the web world. Of course, there are some that these software just won't meet the needs of, so he mentions those too - Meebo with Lighttpd, Alexaholic with IIS and SQL Server, and TechCrunch/FeedBurner with Java and Tomcat.
