My original post detailing how I recreated Apple's flip-style counter is a popular one, and I get many questions about how to properly implement it. It didn't take long before I saw some shortcomings to the original technique I used, so I thought it was time to revisit the counter and make some improvements.
I rely heavily on regular expressions when processing old data. Like my post about cleaning phone numbers, I'll demonstrate another example of how useful regex can be when dealing with unruly data.
Clicky is an amazing web analytics service. Its killer feature is the ability see data in real-time, allowing you to watch your visitors as they browse your site.
I love Clicky, and I love their API. Because the analytics data is available immediately, I found myself wishing I could have a constant notification of how many visitors were on my site without having to leave a tab or window open all the time.
