From: benn686@... Date: 2007-12-11T07:40:01+09:00 Subject: So many languages/tools, so very confusing! Ruby, Ajax, Flex, CSS/HTML/PHP/ASP... I understand these are programming languages that are used to design database rich websites.. however, are these all mutually exclusive? I know a while back, Cold Fusion was Hot, but now that is considered obsolete.. Flex is the same thing as flash, but can be used on the desktop instead of on a webpage, is that correct? Ajax builds on CSS/HTML, but has since been replaced by Ruby? Is there a book recommend that gives a broad look at the current state of internet programming.. which is best for what, etc?
