• Looking for a fast hash-function.

  - by Julian

  Hello, I'm looking for a special hash-function. Let's say I have a large list of strings, if I order them by their hash-values they should be ordered quasi randomly. The most important point is: it must be super fast. I've tried md5 and sha1 and they're using to much cpu power. Clashes are not a problem. I'm using javascript, so it shouldn't be too complicated to implement.

• PHP Sessions data lost when changing directory?

  - by Ineffable

  I've got a simple login system using PHP sessions, but just recently it seems that if you visit pages not in a certain directory (/login/) you will always be flagged as not logged in, even when you are. It seems that my session data is being lost when I change directories (say, to /login/user/). I don't think I've touched the code myself since the problem appeared, is there something my web host could have done to my PHP installation that would delete the session data, and is there a workaround?
