What Does GitHub Mean and How Does It Work?


This week, Andreessen Horowitz announced a $100 million investment in GitHub. You could read all over the internet about what GitHub will do with the money, if Andreessen Horowitz made a successful investment, and whether taking such a large investment is positive for GitHub.

But what exactly is GitHub, and why is it so popular among developers? GitHub is a new code sharing and publishing service, as well as a social networking site for programmers, as you may have heard. Both assertions are correct, but none fully explains why GitHub is unique.

Git, an open-source project founded by Linux developer Linus Torvalds, lies at the heart of GitHub. Git, like other version control systems, organizes and stores project revisions, according to Matthew McCullough, a GitHub trainer.

Although Git is most commonly associated with programming, McCullough claims that it can be used to manage any form of file, including Word documents and Final Cut projects. Consider it a file system for every document draft.

Some of Git’s forerunners, such as CVS and Subversion, feature a central “repository” that holds all of a project’s contents.

According to McCullough, when developers make modifications, they are made straight to the central repository.

If you wish to modify a project, you copy the entire repository to your system with distributed version control systems like Git.

You work on your local copy first, then “check-in” your modifications to the central server. Because you don’t have to connect to the server every time you make a change, McCullough claims that this fosters the sharing of more detailed updates.

GitHub is the site that hosts Git repositories, but it also has its features. GitHub is a web-based graphical interface for Git, a command-line application.

Each project includes access control and numerous collaborative capabilities, such as wikis and rudimentary task management tools.

Moving a repository from one user’s account to another – is GitHub’s most popular feature. This gives you the chance and ability to edit a project that you don’t have write access to under your own account.

If you make changes that you’d like to share, you can notify the original owner with a “pull request.” That user can then integrate the modifications detected in your repo with the original repo with a single click of a button.

The three features that make GitHub so powerful are fork, pull request, and merge. Before GitHub, if you want to contribute to an open-source project, you have to manually download the project’s source code,

in other to make your changes locally, create a list of changes called “patch,” and then e-mail the patch to the project’s maintainer, according to Gregg Pollack in the Code School (which just launched a class called TryGit).

The maintainer would then have to assess this patch, which could have been submitted by an unknown sender, and decide whether or not to incorporate the modifications.

According to Pollack, this is when the network effect begins to play a role in GitHub. When you have submitted a pull request, the project’s maintainer could see your profile, including all of your GitHub contributions.

If your patch is accepted, you will receive credit on the original site, as well as a listing in your profile. It functions similarly to a resume in that it aids the maintainer in determining your reputation.

As more people and projects on GitHub, the better the image of possible contributors a project maintainer can obtain. Patches can also be discussed in public.

Even if maintainers do not use the GitHub interface, GitHub can help with contribution management. “I usually just download the patch anyhow or merge from the command line instead of using the merge button,”

explains Isaac Schlueter, the maintainer of the Node.js open source development platform. “However, GitHub provides a centralized location where the patch can be discussed.”

Lowering the entry hurdle democratizes open source development and aids the growth of new projects. “Without GitHub, Node.js would not be what it is today,” Schlueter explains.

GitHub sells private repositories and on-premise instances of its software for businesses in addition to its public open-source repositories.

These solutions will obviously not be able to utilize GitHub’s network effect fully, but they will be able to use the collaboration capabilities. GitHub makes money in this way, but it isn’t alone in the market.

In 2010, Atlassian bought BitBucket, a competitor. Atlassian also released Stash earlier this year, letting you host private, on-premise Git repositories with BitBucket/GitHub-style collaboration tools.

The company also sells developer collaboration tools such as Jira, a bug tracker, and Confluence, a wiki. Atlassian, which received $60 million in capital from Accel Partners in 2010, may have influenced GitHub’s decision to take this round of funding and point to some possible future routes for the company.

Schlueter believes GitHub’s issue tracking functionality could someday compete with JIRA for some projects.

Although the money is private and on-premise hosting, the affection is in the open repositories. Perhaps most crucially, GitHub has evolved into a code samples Library of Alexandria.

Because Git encourages granular change tracking, programmers of all levels can follow in the footsteps of some of the world’s finest coders and learn how they solve difficult challenges.

However, if GitHub were to perish the same way the Library of Alexandria did, it could be rebuilt from all the local forks scattered over the globe by engineers’ laptops.

That is a hell of a legacy for the GitHub crew to leave behind, regardless of how this investment turns out.
