A while back, we posted a collection of the many tutorials, reviews and pointers to web-based resources that we've been compiling on OStatic since it was launched. We've been steadily adding to that collection, and readers have pointed out a few omissions from the original collection. In this post, you'll find an update with even more resources. Whether you're looking for useful Firefox extensions, want to improve your AJAX skills, or you're launching a web-based open source project, check out some of the tips and tutorials found here.
