Software behind Facebook


in Geek stuff, Internet matters

Given its massive scale, it isn’t surprising that Facebook has cooked up some custom software. What I just learned – which is encouraging – is that Facebook is sharing some of its technologies. One particularly interesting example is HipHop. This software takes the PHP code used by many modern websites (including those running on WordPress and MediaWiki) and compiles it into highly optimized C++ which servers process more quickly. While I don’t know much about it, it seems like something that WordPress might be able to usefully incorporate or reproduce in a future version.

Facebook also contributed to highly distributed database Cassandra, which Twitter also uses, as well as a number of other pieces of open source software.

It is nice to see Facebook providing potentially useful code to the wider web community.
