Git is an open-source version control system that allows developers to track changes to code over time, work on projects simultaneously without overwriting each other, and revert to previous versions if needed. GitHub provides a user-friendly interface for hosting Git repositories and collaborating on projects, with features like bug tracking and project management. The presentation introduces Git and GitHub, explaining how they address issues with earlier centralized and distributed version control systems by allowing decentralized, fast collaboration through local cloning of repositories.
Github is a code hosting platform that allows developers to collaborate on projects. It uses Git for version control and storing a project's codebase and file history. Developers can work together using features like forking repositories, creating branches, submitting pull requests, and discussing code changes through issues. This allows teams to efficiently build and maintain projects together.
General introduction of Git and its feature set. Subversion migration strategies using git-svn, subgit or github enterprise. Suitable for different audience types managers, developers, etc.

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. This will be a beginner friendly session where we will explain to you how Git and Github works and how to use it for your future projects as well!
In one of our weekly training, we’ve talked about Git. Here is a quick overview of the main concepts, basic commands and branching strategy, how to work with Git, how to contribute to an OSS project, …
This document discusses code reviews and Git. It provides information on what code reviews are, why they are important, and what reviewers typically look for. It then discusses Git, including what it is, common scenarios like rebasing and merging, and popular Git tools. Best practices for branching, branch management strategies, and the differences between rebasing and merging are also covered. Additional sources with more information on these topics are provided at the end.
Git is a distributed version control system that allows developers to track changes to files over time. It stores snapshots of files and keeps track of file versions, reverting files back to previous states if needed. With Git, work can continue locally even when a server goes down. Some key aspects of Git include storing data as snapshots, having three main states for files (committed, modified, staged), and using branches to develop features separately from the master branch. Basic Git commands allow users to initialize repositories, add/commit changes, push/pull from remote repositories, switch/merge branches, and tag releases.
This document provides an agenda for getting started with git and GitHub. It discusses version control and how git allows tracking changes to files. It explains how to set up git locally and initialize a repository. Basic git commands like add, commit, status, and log are covered. The document also discusses branching in git and what GitHub is. It provides steps for creating a GitHub account and repository and collaborating through forking, cloning, and pull requests. Finally, it discusses the benefits of open source work.
One of the biggest advantages of Git is its branching capabilities. Unlike centralized version control systems, Git branches are cheap and easy to merge. This facilitates the feature branch workflow popular with many Git users.
This document provides an overview of Git and GitHub for contributing to open source projects during Hacktoberfest. It defines version control systems and how Git is a distributed VCS that allows developers to work asynchronously. Key Git commands and GitHub workflows are described, including creating branches, committing changes, and submitting pull requests. The steps for contributing to projects during Hacktoberfest via forking repositories and making pull requests are also outlined.

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025
https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/
Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

4. Classroom Rules
Late Policy:
You will be marked late if I have already finished checking attendance, but you are still welcome to join the class.
Materials for Seat-Work or Quizzes:
Please bring newsprint, a blue or black pen, and preferably a red pen for checking.
What If:
● You forget to bring a pen or newsprint? I’ll give you time to review, during which you can purchase them from the canteen.
● You don’t have a red pen for checking? It’s okay as long as there are no erasures or overwriting on the answers on your newsprint, or it is better if you use a different color pen.
If you fail to follow these instructions after being reminded, your score will be 0 for not adhering to the guidelines. ;)
Quizzes:
Chapter quizzes will be announced in advance, while other quizzes may occur at any time during the course, often following discussions.
** Take note and listen :)
**The purpose of this is to help you get accustomed to following instructions, even the small ones.
After all, in the future, no matter how well you design a system, it could still be rejected if you overlook a single simple
requirement. :)
5. What is version control?
Version control, also known as source control, is the practice of tracking and managing changes to
software code.
Version control systems are software tools that help software teams manage changes to source
code over time so that you can recall specific versions later.
6. Version control helps solve these kinds of problems and provides:
● complete history of every file
● ability to work on independent streams of changes
● ability to trace each change
7. Types of Version Control Systems
Centralized Version Control (CVCS):
● A single server stores all versions of the files.
● Developers “check out” files to make changes.
● Example: Subversion (SVN).
Distributed Version Control (DVCS):
● Each developer has a complete copy of the repository.
● Changes can be committed locally before sharing.
● Example: Git, Mercurial.
8. Why use version control?
Collaboration:
● Multiple developers can work on the same project simultaneously.
● Avoids conflicts by merging changes from different developers.
History Tracking:
● Every change is logged with a timestamp, author, and message.
● Provides a full history of the project.
Backup and Restore:
● Easy to restore previous versions of files.
● Protects against accidental loss of data.
Branching and Merging:
● Allows working on multiple features or fixes in parallel.
● Changes can be merged into the main project seamlessly.
9. Real-World Example of Version Control
Scenario: A team of developers is working on a software project.
Without Version Control:
● Difficulty tracking changes.
● High risk of overwriting each other's work.
● No easy way to revert to a previous stable state.
With Version Control:
● Each developer works on their own branch.
● Changes are tracked, reviewed, and merged.
● Ability to revert to previous versions if a bug is introduced.
10. What is Git?
By far, the most widely used modern version control system in the world today is Git. Git is a mature,
actively maintained open source project originally developed in 2005 by Linus Torvalds, the famous
creator of the Linux operating system kernel.
Git is an example of a DVCS (hence Distributed Version Control System).
11. Performance
Committing new changes, branching, merging and comparing past versions are all optimized for performance.
Unlike some version control software, Git is not fooled by the names of the files when determining what the storage and
version history of the file tree should be, instead, Git focuses on the file content itself.
Security
The content of the files as well as the true relationships between files and directories, versions, tags and commits, all of
these objects in the Git repository are secured with a cryptographically secure hashing algorithm called SHA1.
Flexibility
Git is flexible in several respects: in support for various kinds of nonlinear development workflows, in its efficiency in both
small and large projects and in its compatibility with many existing systems and protocols.
In addition to being distributed, Git has been designed with performance, security and flexibility in mind.
12. Version control with Git
Git is Good:
Git offers the functionality, performance, security, and flexibility that most developers need, making it a strong choice compared to
alternatives.
Git is a De Facto Standard:
Git is widely adopted, making it easy for teams to find developers with Git experience and access to many integrated tools and
services.
Git is a Quality Open Source Project:
Git is a well-supported, open-source project with strong community support, excellent documentation, and a decade of reliable
stewardship.
Criticism of Git:
While Git has a learning curve, especially for new users, its powerful features ultimately enhance development speed and flexibility.
13. Git for developers
Feature branch workflow
Feature branches provide an isolated
environment for every change to your
codebase. When a developer wants to start
working on something—no matter how big
or small—they create a new branch. This
ensures that the main branch always
contains production-quality code.
14. Distributed development
In SVN, each developer gets a working copy that points back to a single central repository. Git, however, is a distributed
version control system. Instead of a working copy, each developer gets their own local repository, complete with a full
history of commits.
15. Pull request
A pull request is a way to ask another developer to merge one of your branches into their repository. This not only
makes it easier for project leads to keep track of changes, but also lets developers initiate discussions around their
work before integrating it with the rest of the codebase.
16. Community
In many circles, Git has come to be the expected version control system for new projects. If your team is using Git,
odds are you won’t have to train new hires on your workflow, because they’ll already be familiar with distributed
development.
17. Fastest release cycle
The ultimate result of feature branches, distributed development, pull requests, and a stable community is a faster
release cycle. These capabilities facilitate an agile workflow where developers are encouraged to share smaller
changes more frequently. I
