About Version control and Git
A version control system, or VCS, tracks the history of changes as people and teams collaborate on projects together. As developers make changes to the project, any earlier version of the project can be recovered at any time.
Developers can review project history to find out:
Which changes were made?
Who made the changes?
When were the changes made?
Why were changes needed?
VCSs give each contributor a unified and consistent view of a project, surfacing work that's already in progress. Seeing a transparent history of changes, who made them, and how they contribute to the development of a project helps team members stay aligned while working independently.
In a distributed version control system, every developer has a full copy of the project and project history. Unlike once popular centralized version control systems, DVCSs don't need a constant connection to a central repository. Git is the most popular distributed version control system. Git is commonly used for both open source and commercial software development, with significant benefits for individuals, teams and businesses.
Git lets developers see the entire timeline of their changes, decisions, and progression of any project in one place. From the moment they access the history of a project, the developer has all the context they need to understand it and start contributing.
Developers work in every time zone. With a DVCS like Git, collaboration can happen any time while maintaining source code integrity. Using branches, developers can safely propose changes to production code.
Businesses using Git can break down communication barriers between teams and keep them focused on doing their best work. Plus, Git makes it possible to align experts across a business to collaborate on major projects.
Creating and managing Repositories
A repository, or Git project, encompasses the entire collection of files and folders associated with a project, along with each file's revision history. The file history appears as snapshots in time called commits. The commits can be organized into multiple lines of development called branches. Because Git is a DVCS, repositories are self-contained units and anyone who has a copy of the repository can access the entire codebase and its history. Using the command line or other ease-of-use interfaces, a Git repository also allows for: interaction with the history, cloning the repository, creating branches, committing, merging, comparing changes across versions of code, and more.
Through platforms like GitHub, Git also provides more opportunities for project transparency and collaboration. Public repositories help teams work together to build the best possible final product.
Importance of Github in collaboration and security
GitHub acts as a central platform where all project files are stored.
It ensures every team member has access to the latest version of the project.
2. Branching and Merging
Developers can create branches to work on features independently without disturbing the main codebase.
Once work is complete, changes can be reviewed and merged into the main branch.
Team members can propose changes using pull requests.
Other members can review the code, provide feedback, and approve changes.
This process ensures high-quality contributions and reduces errors.
GitHub provides an issue tracker to log bugs, suggest improvements, or track tasks.
Issues can be assigned to specific team members, making project management more transparent and efficient.
Integration with tools like Slack and Microsoft Teams allows instant notifications about updates, pull requests, and discussions.
Team members can collaborate in real-time, even across different time zones.
GitHub maintains a detailed history of all changes made to the project.
This allows team members to understand what was changed, by whom, and why.
Developers can fork a repository to experiment or make improvements without affecting the original code.
Teams working on open-source projects benefit from external contributions via forks and pull requests.
GitHub enables teams to maintain detailed documentation for their projects through README files and Wikis.
Clear documentation enhances onboarding and knowledge sharing among team members.
New team members can quickly clone the repository and set up their environment using GitHub.
They can view commit history and documentation to get up to speed.
GitHub integrates with continuous integration/continuous deployment (CI/CD) pipelines to automate testing and deployment.
Teams can collaborate on features while ensuring that the code is always production-ready.
Key loggers also known as keystroke loggers, may be defined as the recording of the key pressed on a system and saved it to a file, and the that file is accessed by the person using this malware. Key logger can be software or can be hardware. Working: Mainly key-loggers are used to steal password or confidential details such as bank information etc. First key-logger was invented in 1970’s and was a hardware key logger and first software key-logger was developed in 1983. 1. Software key-loggers : Software key-loggers are the computer programs which are developed to steal password from the victims computer. However key loggers are used in IT organizations to troubleshoot technical problems with computers and business networks. Also Microsoft windows 10 also has key-logger installed in it.
