Last year my class had a group project, we had to make a site to allow users to book to their favourite clinic, it was in php, I dislike php, if it were for me, I would have developed the backend in python, but I was the only one to know how to do it in my class...
I asked if they cyphered the passwords, they laughed at me, then the presentation day arrived...
The moron who started to make fun of me said "The password is cyphered, it's super secure", then he showed the db, every password but one was clear, the one I put in my form was hashed, the others were readable by anyone, when I saw the teacher's face I started laughing so hard lol
