049 Let’s learn Git

What’s Git?

Git is today the most popular and extensively deployed version control system. Initially built as an open-source project in 2005 by the developer of the Linux operating system, the ecosystem is mature and actively maintained. A significant group of developers depend on Git version control to build many commercial and non-commercial projects. Git-based developers are well thought of and considered as valuable resources. Some of Git’s advantages are:

Performance: Git works very strongly and consistently relative to other version control systems. New code updates can be easily applied, version branches could be quickly applied and merged, and code could also be configured for better performance. Algorithms used to build Git reap the benefits of the deep knowledge stored within, with respect to the properties used to construct actual source code file trees, how files are changed over time, and what kind of file access patterns are being used to retrieve code files as and when required by developers. Git mainly focuses on the file’s contents instead of on the file names when determining the history of the storage and version of the file. Git repository file object formats use many variations of delta encoding and compression techniques to store metadata objects and directory contents.

Safety: Git is specially designed to protect the credibility of the source code. The contents of the file and the relationship between the file and folders, tags, commits, versions, etc. are cryptographically encrypted using an algorithm called SHA1 that protects the code and changes the history against unintentional and malicious damage. You can be sure that Git has an authentic content history with your source code.

Flexibility: Git’s primary design goal is the kind of versatility it provides to accommodate many forms of non-linear development workflows and its reliability in the handling of both small-scale and large-scale projects and protocols. It is specifically designed to help tagging and branching operations and to store each, and every task carried out by the user as an integral part of the ‘shift’ history. All version control systems do not provide this function.

Wide recognition: Git provides the kind of efficiency, functionality, protection and versatility that most developers and teams need to build their projects, big or small. Compared to the other VCS, Git is the most commonly accepted framework due to its generally accepted usability and performance requirements.

The truth about why Git has become so popular:

Saves your time: Imagine that any time you move your mouse, you’d have to wait 5 seconds. Pretty irritating, huh? It’s just the same with version control – we’re only talking about a few seconds per command, too, but it adds up pretty quickly on your working day. Git is lightning fast, however.

Work offline: What if you’re going to work while you’re on the move? With centralised VCS like Subversion or CVS, you’re stuck when you’re not linked to the central repository. With Git, almost anything is possible on your local machine: commit, search the entire history of your project, merge or build branches, etc. Git eases your life wherever you want to function.
