Fork (software development) - Wikipedia. In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community, a form of schism. However, licensed forks of proprietary software (e. Unix) also happen. Etymology. By doing this, you can give the whole community a chance to benefit from your changes.

Access to the source code is a precondition for this. Derived Works: The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.

The Software Freedom Law Center provides legal representation and other law related services to protect and advance Free and Open Source Software.

In free software, forks often result from a schism over different goals or personality clashes. In a fork, both parties assume nearly identical code bases, but typically only the larger group, or whoever controls the Web site, will retain the full original name and the associated user community. Thus, there is a reputation penalty associated with forking.

Raymond, in his essay Homesteading the Noosphere. He notes in the Jargon File: Forking is considered a Bad Thing—not merely because it implies a lot of wasted effort in the future, but because forks tend to be accompanied by a great deal of strife and acrimony between the successor groups over issues of legitimacy, succession, and design direction. There is serious social pressure against forking. As a result, major forks (such as the Gnu- Emacs/XEmacs split, the fissioning of the 3. BSD group into three daughter projects, and the short- lived GCC/EGCS split) are rare enough that they are remembered individually in hacker folklore.

Wheeler notes. This is by far the most common case. It is easy to declare a fork, but considerable effort to continue independent development and support. Edit Foto Gratis Dan Mudah Sabah. A re- merging of the fork (e.

Sites such as Git. Hub, Bitbucket and Launchpad provide free DVCS hosting expressly supporting independent branches, such that the technical, social and financial barriers to forking a source code repository are massively reduced, and Git. Hub uses . An exception is when the forked software is designed to be a drop- in replacement for the original project, e. Maria. DB for My. SQL. Proprietary code is thus more commonly forked when the owner needs to develop two or more versions, such as a windowed version and a command line version, or versions for differing operating systems, such as a word processor for IBM PC compatible machines and Macintosh computers. Generally, such internal forks will concentrate on having the same look, feel, data format, and behavior between platforms so that a user familiar with one can also be productive or share documents generated on the other.

Free software developers guarantee everyone equal rights to their programs; any user can study the source code, modify it, and share the program. HARDWARE INFORMATION. What is WRT54GS? The WRT54GS Wireless-G Broadband Router with SpeedBooster. It acts as a wireless access point. The word fork stems from the Latin word furca, meaning a "fork or similarly shaped instrument." "Fork" in the meaning of "to divide in branches, go.

This is almost always an economic decision to generate a greater market share and thus pay back the associated extra development costs created by the fork.
