SiteUptime Web Site Monitoring Service

Sitepoint's web devlopment books have helped me out on many occasions both for finding a quick solution to a problem but also to level out my knowlegde in weaker areas (JavaScript, I'm looking at you!). I am recommending the following titles from my bookshelf:

Many years and a lot of experience later I was still able to take away some gems from this book, and there are plenty I wish I had thought of beforehand.

The Art & Science Of JavaScript

The author line-up for this book says it all. 7 excellent developers show you how to get your JavaScript coding up to speed with 7 chapters of great theory, code and examples. Metaprogramming with JavaScript (chapter 5 from Dan Webb) really helped me iron out some things I was missing about JavaScript. That said each chapter really helped me to develop my JavaScript skills beyond simple Ajax calls and html insertion with libs like JQuery.
