5 Doubts You Should Clarify About Facebook
Facebook is a social networking service originally launched as FaceMash on October 28, 2003, before changing its name to TheFacebook on February 4, 2004. It was founded by Mark Zuckerberg and college roommates and fellow Harvard University students, in particular Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The website's membership was initially limited by the founders to Harvard students but was expanded to other colleges in the Boston area, the Ivy League, and gradually most universities in the United States and Canada, corporations, and by September 2006, to everyone with a valid email address along with an age requirement of being 13 and older.

What is facebook's architecture?
Facebook is developed as one monolithic application. According to an interview in 2012 with Facebook build engineer Chuck Rossi, Facebook compiles into a 1.5 GB binary blob which is then distributed to the servers using a custom BitTorrent-based release system. Rossi stated that it takes about 15 minutes to build and 15 minutes to release to the servers. The build and release process has zero downtime. Changes to Facebook are rolled out daily.
Facebook used a combination platform based on HBase to store data across distributed machines. Using a tailing architecture, events are stored in log files, and the logs are tailed. The system rolls these events up and writes them to storage. The user interface then pulls the data out and displays it to users. Facebook handles requests as AJAX behavior. These requests are written to a log file using Scribe (developed by Facebook).
Data is read from these log files using Ptail, an internally built tool to aggregate data from multiple Scribe stores. It tails the log files and pulls data out. Ptail data are separated into three streams and sent to clusters in different data centers (Plugin impression, News feed impressions, Actions (plugin + news feed)). Puma is used to manage periods of high data flow (Input/Output or IO). Data is processed in batches to lessen the number of times needed to read and write under high-demand periods. (A hot article generates many impressions and news feed impressions that cause huge data skews.) Batches are taken every 1.5 seconds, limited by memory used when creating a hash table.
Data is then output in PHP format. The backend is written in Java. Thrift is used as the messaging format so PHP programs can query Java services. Caching solutions display pages more quickly. The data is then sent to Map Reduce servers where it is queried via Hive. This serves as a backup as the data can be recovered from Hive.

How does facebook's "People you may know" work?
Today, we use contacts uploaded to Facebook and Messenger to inform PYMK suggestions," Facebook spokesperson Matt Steinfeld told Gizmodo in 2017.
And that's only one of Facebook's assets. The company also owns Instagram, WhatsApp, and dozens of other services. But which services influence "People You May Know" suggestions? That's still unclear.

At the end of the day, that point is also moot. Facebook doesn't even need YOU to input your info for the platform to collect data on you — the company can apparently use your friends' info to gather data about you too. "People You May Know suggestions may be based on contact information we receive from people and their friends. Sometimes this means that a friend or someone you know might upload contact information — like an email address or phone number — that we associate with you," Steinfeld told Gizmodo in the 2017 article.
How can you know if someone blocked you on Facebook?
Normally, Facebook users can be searched. Try searching the person's name on Facebook by typing their name into the search bar at the top of the page.
If you know that their profile has not been deleted and the friend no longer appears or you receive the message stating that the content is not available, they have likely blocked or unfriended you.
OR
Try sending the friend a message using Facebook Messenger. If you see an error message, they have likely blocked you, unfriended you, or their profile has been deleted.
