Version Control Applications

• Version control systems (VCS) most commonly run as stand-alone applications, but revision control is also embedded in various types of software such as word processors and spreadsheets, e.g., Google Docs and Sheets and in various content management systems, e.g., Wikipedia's Page history. Revision control allows for the ability to revert a document to a previous revision, which is critical for allowing editors to track each other's edits, correct mistakes, and defend against vandalism and spamming. Software tools for revision control are essential for the organization of multi-developer projects.

What are the top 5 Version Control Applications

• CVS is the grandfather of revision control systems. It was first released in 1986, and Google Code still hosts the original Usenet post announcing CVS. CVS is the de facto standard and is installed virtually everywhere. However, the code base isn’t as fully featured as SVN or other solutions. The learning curve isn’t too steep for CVS, and it’s a very simple system for making sure files and revisions are kept up to date. While CVS may be an older technology, it’s still quite useful for any designer or developer for backing up and sharing files. Tortoise CVS is a great client for CVS on Windows, and there are many different IDEs, such as Xcode (Mac), Eclipse, NetBeans and Emacs, that use CVS.
• Subversion is probably the version control system with the widest adoption. Most open-source projects use Subversion as a repository because other larger projects, such as SourceForge, Apache, Python, Ruby and many others, use it as well. Google Code uses Subversion exclusively to distribute code. Because of Subversion’s popularity, many different Subversion clients are available. If you’re a Windows user, Tortoise SVN is a great file browser for viewing, editing and modifying your Subversion code base. If you’re on a Mac, Versions is an elegant client that provides a “pleasant way to work with Subversion.” Xcode is Apple’s developer environment and Subversion client that ships with Leopard on a Mac.
• Git is the new fast-rising star of version control systems. Initially developed by Linux kernel creator Linus Torvalds, Git has recently taken the Web development community by storm. Git offers a much different type of version control in that it’s a distributed version control system. With a distributed version control system, there isn’t one centralized code base to pull the code from. Different branches hold different parts of the code. Other version control systems, such as SVN and CVS, use centralized version control, meaning that only one master copy of the software is used.
• Mercurial is another open-source distributed version control system, like Git. Mercurial was designed for larger projects, most likely outside the scope of designers and independent Web developers. That doesn’t mean that small development teams can’t or shouldn’t use it. Mercurial is extremely fast, and the creators built the software with performance as the most important feature. The name “mercurial” is an adjective that means “Relating to or having characteristics (eloquence, swiftness, cleverness) attributed to the god Mercury.”
• Bazaar is yet another distributed version control system, like Mercurial and Git, that offers a very friendly user experience. It calls itself “Version control for human beings.” It supports many different types of workflows, from solo to centralized to decentralized, with many variations in between. One of the main features of Bazaar is the fine-grained control you’ll have over the setup. As shown with the workflows, you can use it to fit almost any scenario of users and setups. This is a great revision control system for nearly any project because it’s so easy to modify. It’s also embeddable, so you can add it to existing projects. Bazaar also has a strong community that maintains things like plug-ins and lots of third-party tools, such as GUI software to add a graphical interface to the system.
• LibreSource is a Web portal used to manage collaborative projects. It’s based on Java/J2EE and is more a set of visual collaborative tools to help facilitate projects and teams. While the other systems discussed so far have been designed more on a “command line” level, LibreSource is centered more on tools that don’t have a big learning curve. It has built-in features such as Wiki pages, forums, trackers, Synchronizers, Subversion repositories, files, download areas, drop boxes, forms, instant messaging and more. Think of LibreSource as a collaboration hub for project development. LibreSource is perfect for the developer or designer who doesn’t want to learn lots of technical jargon and wants to focus more on communication with the project’s members. Just install the package and start collaborating, without facing much of a learning curve.
• Monotone is the baby of the distributed revision control bunch. While many of Monotone’s peers focus on performance, Monotone places higher value on integrity than performance. In fact, it can take quite a bit of time for a new user of Monotone to simply download the initial repository due to the extensive validation and authentication required. Monotone is fairly easy to learn if you’re familiar with CVS systems, and it can import previous CVS projects. However, it’s not quite as popular as other version control systems.

What is Git?

• Git (/g?t/[6]) is a version control system that is widely used for software development and other version control tasks. It is a distributed revision control system with an emphasis on speed, data integrity, and support for distributed, non-linear workflows. Git was created by Linus Torvalds in 2005 for development of the Linux kernel, with other kernel developers contributing to its initial development.

What is GitHub?

• GitHub is a web-based Git repository hosting service. It offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features. Unlike Git, which is strictly a command-line tool, GitHub provides a Web-based graphical interface and desktop as well as mobile integration. It also provides access control and several collaboration features such as bug tracking, feature requests, task management, and wikis for every project.

What is the difference between Git and GitHub?

• Git is the distributed version control system. Git is responsible for keeping track of changes to content (usually source code files), and it provides mechanisms for sharing that content with others. GitHub is a company that provides Git repository hosting.

Terms:

REPOSITORY - A software repository is a storage location from which software packages may be retrieved and installed on a computer.

COMMIT - Stores the current contents of the index in a new commit along with a log message from the user describing the changes.

FORK - A fork is a copy of a repository. Forking a repository allows you to freely experiment with changes without affecting the original project. Most commonly, forks are used to either propose changes to someone else's project or to use someone else's project as a starting point for your own idea.

PULL - Pull coding or client pull is a style of network communication where the initial request for data originates from the client, and then is responded to by the server. The reverse is known as push technology, where the server pushes data to clients. Usually, customers will look for a site and visit only if it provides helpful and attractive content to display. The pull code is effective and economical when advertising to open, unidentified potential customers world wide. It is more effective for the customer when he searches for a specific item.

PUSH - Push, or server push, describes a style of Internet-based communication where the request for a given transaction is initiated by the publisher or central server. It is contrasted with pull/get, where the request for the transmission of information is initiated by the receiver or client.
