Stack Overflow is a website featuring questions and answers on a wide range of topics in computer programming.[2][3][4]

The website features the ability for users to ask and answer questions, and, through membership and active participation, to vote questions and answers up or down and edit questions and answers in a wiki fashion. Users of Stack Overflow can earn reputation points and "badges"; for example, a person is awarded 10 reputation points for receiving an "up" vote on an answer given to a question, and can receive badges for their valued contributions.[5]

As of February 2010, Stack Overflow has about 135,000 registered users,[6] and 515,000 questions. Based on tags assigned to the questions, the most common topics on the site are C#, Java, .NET, ASP.NET, PHP, JavaScript, C++, jQuery, Python, and iPhone.[7]

History

The website was created by Jeff Atwood and Joel Spolsky in 2008[8][9] as a more open alternative to earlier forums such as Experts Exchange. The name for the website was chosen by voting in April 2008 by readers of Coding Horror, Atwood's popular programming blog.[10] The design of the Stack Overflow logo was also put to a vote. On July 31, 2008, Jeff Atwood sent out invitations encouraging his subscribers to take part in the private beta of the new website, limiting its use to those willing to test out the new software. On September 15, 2008 it was announced the public beta version was in session and that the general public was now able to use it to seek assistance on programming related issues.

Technology

Stack Overflow is written in ASP.NET using the ASP.NET MVC (Model-View-Controller) framework.[11] Unregistered users have access to most of the site's functionality, while users that sign in using the OpenID service can gain access to more functionality, e.g. establishing a profile.

Sister sites

In April 2009, the owners of Stack Overflow began a private beta for Server Fault, a sister site. The site deals exclusively with questions and answers related to the field of system administration. The site is in open beta as of June 2009.

Super User

Super User, a sister site dedicated to questions from all computer "power users",[12] rather than just programmers or system administrators, entered a "semi-private beta" in July 2009[13] and was launched publicly on August 18, 2009.[14]

Meta Stack Overflow

Meta Stack Overflow became the site for questions about the sister sites themselves and various other meta-level discussions.[15] Most support, feature-request and bug report entries were moved from stackoverflow.uservoice.com in July 2009.[16]

Careers

Careers, located at careers.stackoverflow.com, is a new undertaking by the Stack Overflow team. The goal of the careers site is to create a job-seeking service aimed at companies that are seeking top quality programmers. Careers allows Stackoverflow.com members to link their Stack Overflow profile with their online CV created on the careers site, allowing employers to browse their contribution history to Stack Overflow.

StackExchange

A spin off of the software called StackExchange has been released by Fog Creek Software to allow third parties to build communities similar to Stack Overflow around other topics.[17] Some examples of sites running on StackExchange are:
