With over billions of people using Facebook during different times of day and night, it has sufficient data that can reveal its users sleeping habits.
The social networking platform can easily tell you when your friends come online, when they are chatting or “Liking” your Facebook updates. A Danish programmer named Søren Louv-Jansen has created a program that fetches data from Facebook and then it can help you reveal your friends sleeping habits or sleeping pattern. The program gathers Digital IDs and their “last active” receipts and then creates accurate profiles of your friends sleeping habits. Would you like to try out the code? He has uploaded his code to the code-sharing websites GitHub and has explained in a Medium blog post how the code works and how you can use it to reveal your friend’s sleeping habits.
Accessing the Facebook data that can reveal people’s sleeping habits isn’t as geeky as it may sound. Yes, it requires a program, but you can view the core data by simply visiting Messenger.com and then viewing the source code of the website. He explains, “Many people visit Facebook as the first thing in the morning, and the last thing before going to bed. It is therefore possible to get a good impression of their sleeping habits. By creating a simple service that checks Facebook every 10 minutes, I’m able to get an accurate picture of my friend’s Facebook usage.”
Here is a video of the code in action. It uses the Facebook data and then processes it in such a manner that it can reveal the sleeping habits of all the persons you need to track.
Facebook openly reveals its users’ location and the “last active” time stamp. Louv-Jansen’s program repeatedly checks Facebook to gather publicly available information. According to an interview given to Washington Post, he says that his program can reveal the sleeping habits of 30% of his friends extremely well and 70% of his friends somewhat effectively.
Of course in order to reveal sleeping habits based on the way people use Facebook requires people to check Facebook before going to bed and immediately after waking up. Do lots of people do this? Most of the people I know don’t. I myself check Facebook 4-5 hours after I have been working on my computer and unless I’m looking for an extremely important update, I never check Facebook 2 hours before going to bed because I’m busy doing other things or watching a movie with my wife. So it would be very difficult for my friends to use the program that can reveal my sleeping habits.
