Just rolled out the latest version of a website for my client this week. VERY major overhaul of a very aging product. And thus far, I'd say it's been most successful :)
The most noticable things have been the speed increase (woo yeah!), new look and feel, and that I rewrote almost every line of code for it ;) There's a pretty nice feature set for registered users too. It's almost like I paid attention to all the issues people had with the original version of the site and did something to address them ;) Every day I sing praise to CGI::Application, HTML::Template, and CGI::Session ;)
Also learned some other good things along the way. Namely, about how to build and maintain a better firewall (thank you, OpenBSD!).
It's been a good week.
