As you may know, I have been ta-ing a course in operating systems. We just finished covering sockets and in the last lab I gave a socket demo where I show three different ways a server can listen on a socket.

The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field.

If you use a lot of online services it also means that you have got a lot of passwords and usernames to remember. Aware of this issue, all Internet browsers have got a special feature which, as soon as you login your email account for example, prompt you to save password and username so that, next time you will use the service again, the browser will fill in the login interface for you. However, while the username is fully displayed, the password is hidden by asterisks. Now, if for any reason you don’t remember such a password you won’t have any way to recover it. Usually, to get it back, you will have to buy a special piece of software.
