    telling me php doesn't scale is like telling me java supports oo programming. five minutes of looking at that language told me that. the db stuff was slightly more interesting - more evidence as to the death of the traditional rdbms but in the end not that surprising. anything of facebooks scale can't support traditional clustering and has to drop to partitioning of some kind.

    their platform sounds like a mess of a variety of languages. "right language for the task" sounds to me like a euphemism for "i can't really control my vastly more experienced developers"

    This sounds to me like the a critique by someone who is afraid to move beyond their comfort zone.

    Dunno about that but would note that Amazon also use a variety of languages and it's encouraged - Vogels says:

    "You build a small team. You give them this problem. And at Amazon, they're allowed to solve that problem in any way they see fit, as long as it is through this hardened API. They can pick the tools they want. They can do any design methodology they want as long as they deliver the actual functionality that they've been tasked with......We have some requirements: that services has to be monitorable, that they have to be tractable in all sorts of different ways. But in essence, operation is all up to the service owners themselves. This allows for a large-let's say controlled chaos-which actually works very well because everybody's responsible for their own services."

    Hi Dinh,

    Your link goes to one particular slide (6.swf). I can get to the others by editing the url, but is the a starting page, or a way to download all of the slides at once?

    Thanks for posting this presentation.

    "[...]the other reason we use php apart from the fact that we started of on it[...]"

    With this phrase I just would like to ask, what would you use if you could go back to the very beginning of Facebook with the nowadays advances ?

    Java, Php, Ruby, Python etc. ?
    Rails, Zend, Symfony, your framework, reinventing the wheel etc. ?
