What is Git?
Git is a software for tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development. Its goals include speed, data integrity, and support for distributed, non-linear workflows.
Initial release: April 7, 2005
Creators: Linus Torvalds, Junio C Hamano
What is Git?
- Repository: repo is a collection of source code. A repository has commits to the project.
- Commits: a commit logs a change or series of changes made to files in the repository. A commit has a unique hash that is used to keep track of files changed in the past. A series of commits comprises the Git history.
-
Branches: a branch is essentially a unique set of code changes with a unique name. Each repository has one or more branches. The branch where all the changes eventually get merged into is named
mastermain.
What Is GitHub?
"GitHub is a website and cloud-based service that helps developers store and manage code, as well as track and control changes. GitHub offers a cloud-based Git repository hosting service. Essentially, it makes it a lot easier for individuals and teams to use Git for version control and collaboration.
Anyone can sign up and host a code repository for free, which makes GitHub especially popular with open-source projects."
Git
Is a version control system that lets you manage and keep track of your source code history

In simple terms:
GitHub alternatives
- GitLab (gitlab.com) -> most similar to GitHub, with public repositories, profiles, and Pages (hosting)
- Atlassian Bitbucket (bitbucket.org)
- Azure Repos (azure.microsoft.com/en-us/services/devops/repos)
- AWS CodeCommit (aws.amazon.com/codecommit)
- Google Cloud Source Repositories (cloud.google.com/source-repositories)
It's common to see Software Developers mention only "git" in theirs profiles/resumes. There are other solutions such as GitHub, and if the Software Developer knows Git, for sure he will not have problems using other solutions adopted by any company.
Tips:
- Create and log in with your GitHub account to have access to more information and resources
- About URLs:
- https://github.com/AbraaoHonorio is a Github user profile
- https://abraaohonorio.github.io is a Website made by using a free resource named Github Pages.
User profile
A custom and optional page, manually made by the user
Projects pinned by the user, that use to be the most relevant. Each project shows the used language and are links to click and access more info.
Activity history
User info
Connections
Repositories (projects)
When visiting a repository, we can find more information:
Users and contributors
Numbers are links for users who:
1) Choose to receive notifications about this project
2) Created a copy of the project (fork), which is useful for contribution
Technologies
README file
Description and tags
BRANCH name
User profile
It's common to find some repositories like those below. Take a look and let's understand about they.
User profile
A repository named as {username} is a custom page with information, that was created by the user and is displayed in the "Overview" tab.
User profile
A repository named as {username}.github.io is a website, hosted for free by using the resource Github Pages.
User profile
Attention to all details when looking into a GitHub profile. Example: this GitHub user did't fill his profile with information. But we can see some "github.io" repositories. One of them is "forked" from another user, that means "it's a copy of other project for contribution or studying". "Forked" is good, it shows that the user had been interested in learning/collaborating someone else's project.
User profile
In previous slide we found an GitHub user without information. But if we open the website "{username}.github.io" we can find all contact info.
People
Organization profile
All projects
Main projects
"People" will list all software developers related to the organization
Organization profile
This resource allows to apply a lot of filters to find users.
D.I.Y.: fill in some filters and click in the "Search" button.
Using advanced search
Using advanced search
As result of the previous search, we got some results:
Using APIs
activity
- GET {baseUrl}/orgs/{org}/events
- GET {baseUrl}/users/{username}/events/public
Using these public docs of Github REST API, it's possible to use some GET requests related to events.
Let's try the two endpoints below on the next slides.
GET /users/{username}/events/public
Using this API is possible to find user historic actions. It's easy to find a public user e-mail address.
Let's see an example:
GET /orgs/{org}/events
Using this API is possible to find historic actions related to an organization. It's useful to find users' profiles.
Let's see an example:
Property html_url
In the previous slide, we found a GitHub user related to the organization "globocom". Now we can navigate into his profile:
