3. INTRODUCTION TO FACEBOOK

4. Facebook is an American online social media and social
networking service company based in Menlo Park, California. Its
website was launched on February 4, 2004, by Mark Zuckerberg,
along with fellow Harvard College students and roommates
Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris
Hughes.
The founders initially limited the website's membership to
Harvard students. Later they expanded it to higher education
institutions in the Boston area, the Ivy League schools, and
Stanford University. Facebook gradually added support for
students at various other universities, and eventually to high
school students.

5. HISTORY
 2003–2006: Thefacebook, Thiel investment, and name change
 Zuckerberg wrote a program called "Facemash" in 2003 while attending Harvard
University as a sophomore (second year student). According to The Harvard
Crimson, the site was comparable to Hot or Not and used "photos compiled
from the online facebooks of nine Houses, placing two next to each other at a
time and asking users to choose the "hotter" person". Facemash attracted 450
visitors and 22,000 photo-views in its first four hours online. The Facemash site
was quickly forwarded to several campus group list-servers, but was shut down
a few days later by the Harvard administration.
 Zuckerberg faced expulsion and was charged by the administration with breach
of security, violating copyrights, and violating individual privacy. Ultimately, the
charges were dropped. Zuckerberg expanded on this initial project that
semester by creating a social study tool ahead of an art history final exam. He
uploaded all art images to a website, each of which was featured with a
corresponding comments section, then shared the site with his classmates, and
people started sharing notes.

6. WEBSITE
 The website's primary color is blue as Zuckerberg is red-green colorblind, a
realization that occurred after a test undertaken around 2007; he explained
in 2010: "blue is the richest color for me—I can see all of blue. Facebook is
built in PHP which is compiled with HipHop for PHP, a "source code
transformer" built by Facebook engineers that turns PHP into C++. The
deployment of HipHop reportedly reduced average CPU consumption on
Facebook servers by 50%.
 Facebook is developed as one monolithic application. According to an
interview in 2012 with Chuck Rossi, a build engineer at Facebook, 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 and new changes to Facebook are
rolled out daily.
