This article is about the social networking service. For the type of directory, see face book. Facebook (formerly [thefacebook]) is an online social networking service headquartered in Menlo Park, California. Facebook was founded on February 4, 2004, by Mark Zuckerberg with his college roommates and fellow Harvard University students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes.[7] The founders had initially limited the website's membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities and later to high-school students. Facebook now allows anyone who claims to be at least 13 years old to become a registered user of the website.[8] Its name comes from a colloquialism for the directory given to it by American universities students.[9] History College-only service Service available to the general public Initial public offering

Dorsey, then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group.[15][16] The original project code name for the service was twttr, an idea that Williams later ascribed to Noah Glass,[17] inspired by Flickr and the five-character length of American SMS short codes.

Ten Commandments of Computer Ethics The Ten Commandments of Computer Ethics were created in 1992 by the Computer Ethics Institute. The commandments were introduced in the paper "In Pursuit of a 'Ten Commandments' for Computer Ethics" by Ramon C. Barquin as a means to create "a set of standards to guide and instruct people in the ethical use of computers." [1] The Ten Commandments of Computer Ethics copies the style of the Ten Commandments from The Bible and uses the archaic "thou shalt" and "thou shalt not" found in the King James version. The commandments have been widely quoted in computer ethics literature [2] but also have been criticized by both the hacker community [3] and some in academia. For instance, Dr. Ben Fairweather of the "Centre for Computing and Social Responsibility" has described them as "simplistic" and overly restrictive.[4]

Getting Things Done The GTD method rests on the idea of moving planned tasks and projects out of the mind by recording them externally and then breaking them into actionable work items. This allows attention to be focused on taking action on tasks, instead of recalling them.[2] First published in 2001, a revised edition of the book was released in 2015 to reflect the changes in information technology during the preceding decade. Themes[edit] Allen first demonstrates stress reduction from the method with the following exercise, centered on a task that has an unclear outcome or whose next action is not defined.

Collaborative real-time editor A collaborative editor is a form of collaborative software application that allows several people to edit a computer file using different computers, a practice called collaborative editing. There are two types of collaborative editing: real-time and non-real-time. In real-time collaborative editing (RTCE), users can edit the same file simultaneously, whereas in Non-real-time collaborative editing, the users do not edit the same file at the same time (similar to revision control systems). Collaborative real-time editors generally permit both the above modes of editing in any given instance.
