i'm more into fp and using lisp so for my experience-based suggestion the dev technologies are all aligned (lisp, jquery, script-fu)

a less parallel could be erlang, jquery, python-fu where one needs to learn 3 distincts techs -> takes more time

for oop, it could be ruby, prototype, <insert ruby for photo>, and of course sql

i didn't put sql because i don't use it now since my data structure (linked list) is not easily mapped into tables shrug and i use a lot of regex on top of it ... but it would be sqlite if i have to use sql again

abundant open source options ... choose the smallest set
