Everybody talks about security but most of the people still save md5(password) in their databases. This is not funny. Reversing a simple and even a average password is not that hard.
I once wrote this tiny class that generates secure enough password hashes.

I first thought about putting this queue in SQL but did not want the whole SQL overhead and such and remembered a blog artice about memcache queues a once read.

For all of you who liked phpMyAdmin2 where all relevant information was visible at any time, sould be annoyed be the new slider effects in phpMyAdmin3.

A workmate mentioned, that floor($i) could be replaced with (int)$i.
I found this very interresting and did some researched about that.

floor($i); will return a float that will have the lower value of $i.
A cast will just convert $i to an integer which will cut of all decimals.
So by symptoms, these two methods are equivalent. Even if floor returns a float, PHP does dynamic casting of its variables.
