Facebook PHP Source Code

Ok, so one guy got to see Facebook’s source code on his screen, probably due to some bad upgrade, lord knows why, the code appeared on his screen, he then copied and pasted it to some forums, and then Facebook lawyers were threatening him.

Too late!, it’s all over the place. Look for it no more, see how these noobs code, its horrible… Home Page code included.

How embarrasing man, let’s look at this line by line and make jokes or try to learn from them. Wonder what all the people that are doing Facebook apps are going to think about the style of where their code is running on top of.

  1. not trying to defend anyone`s code or anything like that, but in terms of money…. if it works i`ll get paid…
    if someone tries to add something in my code or try to change some values … for sure he`ll be spending some time doing that, and that my friend is mo` money for that guy, and i still have my 2 cents in my pockets lol….

    Hey just kidding, do not take this seriously

    But what i do think is:
    – do some programmers make their code hard to read just for the fun of it? or because he wants to be attached to the same customer?
