  2. Wikipedia:FAQ/Forking - Wikipedia

    en.wikipedia.org/wiki/Wikipedia:FAQ/Forking

    A mirror is an exact copy. A fork is a copy that has been changed, diverging from the original path of development, like a fork in the road. Mirrors provide alternative access to Wikipedia (when access is needed offline, or when the Wikipedia site is down). Forks allow you to start with Wikipedia content, and transform it into something else.

  3. Fork–join model - Wikipedia

    en.wikipedia.org/wiki/Fork–join_model

    Implementations of the fork–join model will typically fork tasks, fibers or lightweight threads, not operating-system-level "heavyweight" threads or processes, and use a thread pool to execute these tasks: the fork primitive allows the programmer to specify potential parallelism, which the implementation then maps onto actual parallel execution. [1]

  4. Distributed version control - Wikipedia

    en.wikipedia.org/wiki/Distributed_version_control

    The maintainer has to merge the pull request if the contribution should become part of the source base. [12] The developer creates a pull request to notify maintainers of a new change; a comment thread is associated with each pull request. This allows for focused discussion of code changes. Submitted pull requests are visible to anyone with ...

  5. Sort-merge join - Wikipedia

    en.wikipedia.org/wiki/Sort-merge_join

    The sort-merge join (also known as merge join) is a join algorithm and is used in the implementation of a relational database management system. The basic problem of a join algorithm is to find, for each distinct value of the join attribute, the set of tuples in each relation which display that value. The key idea of the sort-merge algorithm is ...

  6. Merge (SQL) - Wikipedia

    en.wikipedia.org/wiki/Merge_(SQL)

    A relational database management system uses SQL MERGE (also called upsert) statements to INSERT new records or UPDATE or DELETE existing records depending on whether condition matches. It was officially introduced in the SQL:2003 standard, and expanded [ citation needed ] in the SQL:2008 standard.

  7. Wikipedia:Content forks

    en.wikipedia.org/wiki/Wikipedia:Content_forks

    If the content fork was unjustified, the more recent article should be merged into the main article. Redundant content forks of page types other than articles are rarer, but they do occur. Note that "redundant content fork" is an idiom, not to be taken literally. All content forks are redundant, that's their nature, even the acceptable ones ...

  8. Fork (software development) - Wikipedia

    en.wikipedia.org/wiki/Fork_(software_development)

    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. [9] The relationship between the different teams can be cordial or very bitter.

  9. Fork and pull model - Wikipedia

    en.wikipedia.org/wiki/Fork_and_pull_model

    Fork and pull model refers to a software development model mostly used on GitHub, where multiple developers working on an open, shared project make their own contributions by sharing a main repository and pushing changes after granted pull request by integrator users.
