The Middle man is the thing that imposed Erlang only in the Erlang world. If people try to talk to each other, the complexity of the program is O(N²)… - Joe Armstrong

I thought if you multiply two integers together, you get an integer. But apparently you don't in PHP. You get a floating point number, which gets bigger and bigger and that's okay. Until you get to factorial(171), and then you get "INF". I don't know what "INF" is. I think it's infinity actually. But in that case, it's probably wrong, because infinity is awfully big. Bigger than factorial(171).

What's legacy code? That's dead programmers stuff, not only there are no comment in it, you can't ask people because they are dead. It written in languages that nobody understand, there is no specification and yet it works beautifully!

Sometimes changing one line of legacy code is incredibly difficult than totally rewriting the entire stuff.
