Hey everyone... I just watched the movie "The social network," and i was just wondering if anyone knows what programming language was used by Mark Zuckerberg to write facebook.com.
According to a quick google search (http://www.google.co.nz/search?q=what+programming+language+is+facebook+written+in) its PHP for the user interface and c++ for some of the backend cron jobs etc.
The front end is 100% PHP. I saw an interview with Zuckerberg saying that when his friend hopped on the project, he bought "Perl for dummies" and read it over the weekend at his parents' house before starting to help, so I assume that Perl was involved in some way at some stage, too.
