Your Facebook Account has Three Passwords

Do you know that you can log into your Facebook account using three different passwords? Just change the case of your main password to get the new one!

This is interesting. You can log into your Facebook account using three passwords – one is the main password that you created and the other passwords can be constructed by toggling the case of characters that form your original password.

For example, if your Facebook password is operati@nGeronimo!, you can convert the uppercase characters to lowercase (and vice-versa) and the toggled password string – OPERATI@NgERONIMO! – will also get you into Facebook.

There’s another variation as well. If the first character of your Facebook password is in small case, just change that character to upper case – like Operati@nGeronimo! – and Facebook will gladly let you in.

You may try these variations with your own password on the Facebook login screen available at facebook.com/login.php.

Multiple Facebook Logins

You don’t just have multiple passwords on Facebook, you can log into Facebook using multiple usernames as well.

The default username is the email address that is associated to your Facebook account but you can also login using your Facebook username (that’s in the vanity URL of your Facebook profile page). Similarly, if you have associated your mobile number with Facebook (which you should for security reasons), you can use that mobile number as your username on the Facebook login screen.

A Stack Exchange thread pointed me to this ZDNet story that explains why Facebook allows users to login through multiple passwords. According to Facebook:

We accept three forms of the user’s password to help overcome the most common reasons that authentic logins are rejected. In addition to the original password, we also accept the password if a user inadvertently has caps lock enabled or their mobile device automatically capitalizes the first character of the password.

Thus, if you have accidentally enabled CAPS Lock on the keyboard, the toggled password would still work on Facebook.

Fonetwish lets you access Facebook on your Mobile Phone Without Internet or a Data Plan in India for Rs 1 per day, unlimited

Do you have an old mobile phone, like the Nokia 1100, that has no browser and can do little more than make phone calls? Or are you stuck in some remote place where there’s no Internet or no other form of data (EGDE/GPRS/3G) connectivity is available?

Not a problem. You can still use your Facebook account in India by dialing *325# (or *fbk#) from your mobile phone – this service requires no data plan or Internet and it will even work on phones of the Stone Age. Here’s a quick tour:

Use Facebook without the Data Plan

Facebook India has partnered with Fonetwish to bring Facebook on every mobile phone without requiring any apps or even the Internet.

You dial the *325# number, then enter your Facebook username and password and you are in. You can then send number based commands to access various features of Facebook, chat with friends who are online, add new people to your friends list, and more.

I played with the service for some time and it was a nice experience overall. If there were a Unix-like shell interface for Facebook, it would be much similar. Fonetwish says that this service is currently available for Airtel, Aircel, Idea and Tata Docomo users in India.

It may be too much work to read your Facebook news feed stories one by one but this is a good option to quickly update your Facebook status or for chatting with friends who are online. The price is reasonable too – you just have pay a subscription fee of 1.00 per day for unlimited usage.

I find myself in a situation where I am logged in remotely to a server and have started a long running process, only to realize that I didnt kick off a screen session before, neither did I use nohup

In such a situation, the disown command comes in handy

disown -h %1

After I background the process, I disown it from the current terminal. The disown prevents a SIGHUP to the process if my terminal dies!

from the man page –

disown [-ar] [-h] [jobspec ...]
Without  options,  each  jobspec is removed from the table of active jobs.  If the -h option is given, each jobspec is not removed from the table, but is marked so that SIGHUP is not sent to the job if the shell receives a SIGHUP.  If no jobspec is present, and  neither  the  -a nor  the -r option is supplied, the current job is used.  If no jobspec is supplied, the -a option means to remove or mark all jobs; the -r option without a jobspec argument restricts operation to running jobs.  The return value is 0 unless a jobspec does  not  specify  a  valid job.

Thats it for a sunday morning! To own something can be a lot of responsibility, disown it and rest in peace
