  Right-click the "Remotes" section header in the sidebar and select "Add Remote Repository" In the dialog, you can enter a name (e.g. "origin") and the remote repo's URL on Github; additionally, you can select your GitHub account Confirm the dialog and the remote will now be connected with your local repository From now on, you can simply use the "Push" button in the toolbar to upload new changes to the remote on GitHub

  Enter  git commit -m "[commit message]" to save the changes to your local repository . You can enter anything for the commit message, but adding -m "[commit message]" specifies what this code change is doing, so it's helpful to be clear and concise. Enter git push origin [branch name] to save your code changes to GitHub.

  In the upper-right corner of any page, select , then click New repository. Type a short, memorable name for your repository. For example, "hello-world". Optionally, add a description of your repository. ... Choose a repository visibility. ... Select Initialize this repository with a README. Click Create repository.

  Version control - also known as source control or revision control - is an important software development practice for tracking and managing changes made to code and other files. It is closely related to source code management. As organizations accelerate delivery of their software solutions through DevOps, controlling and managing different versions of application artifacts — from code to configuration and from design to deployment — becomes increasingly difficult. Version control software facilitates coordination, sharing, and collaboration across the entire software development team. It enables teams to work in distributed and asynchronous environments, manage changes and versions of code and artifacts, and resolve merge conflicts and related anomalies.

 Advantages  of mind mapping are:- Makes it easier to retain information:  The sequential structure of mind maps helps your brain retain information and memorize it quickly. Helps people learn new concepts:  Mind maps help connect concepts and facilitate meaningful learning. Makes learning more engaging:  Mind mapping created deep interactions with content, making the learning process more engaging. Breaks down complex relationships:  Mind maps organize ideas into an easy-to-follow structure that allows you to simplify complex relationships. Improves your creativity:  By using creative freedom to organize your mind map, you can gain a more holistic understanding of how everything connects. Increases productivity:  Mind maps aren’t just pretty; they’re effective too. These diagrams improve your efficiency by speeding up comprehension and allowing you to jump quickly to different applications.

Kanban vs. Scrum Scrum and Kanban are both iterative work systems that rely on process flows and aim to reduce waste. However, there are a few main differences between the two. Kanban Scrum Roles and Responsibilities There are no pre-defined roles for a team. Although there may still be a Project Manager, the team is encouraged to collaborate and chip in when any one person becomes overwhelmed. Each team member has a predefined role, where the Scrum master dictates timelines, Product owner defines goals and objectives and team members execute the work. Due Dates / Delivery Timelines Products and processes are delivered continuously on an as-needed basis (with due dates determined by the business as needed). Deliverables are determined by sprints, or set periods of time in which a set of work must be completed and ready for review. Delegation & Prioritization Uses a “pull system,” or a systematic workflow that allows team members to only “pull” new tasks once the previous task is co...

  Scrum   can help teams complete project deliverables quickly and efficiently. Scrum can help teams complete project deliverables quickly and efficiently Scrum ensures effective use of time and money Large projects are divided into easily manageable sprints Developments are coded and tested during the sprint review Works well for fast-moving development projects The team gets clear visibility through scrum meetings Scrum, being agile, adopts feedback from customers and stakeholders Short sprints enable changes based on feedback a lot more easily The individual effort of each team member is visible during daily scrum meetings

  The Retrospective is the most important Agile ceremony  because it ties perfectly into the heart of Agile—having frequent feedback loops that allow for continuous improvement. In its simplest form, the Retrospective ceremony looks at what went well and what could have gone better; however, the true reason behind the Retrospective is to identify actionable items the team can use to improve their process. By reflecting on both the positive and negative feedback of the sprint, the team finds strengths, which they can hone and play to, as well as weaknesses, which they can address and minimize. Through this repeated feedback loop, the team continues to adjust to deliver the highest quality product possible.

  Sprint planning:  These sessions are what initiate each sprint. Your team decides what work from the product backlog can be completed in the time period, who will complete what tasks, and how you’ll be successful. Daily scrum (or daily stand-up):  These daily check-ups help teams stay on track and mark progress. Each morning, team members discuss what they worked on yesterday, what they’re doing today, and what’s blocking them from moving forward. Sprint review:  At the end of each sprint cycle, teams meet to demo what they’ve shipped and get early feedback from stakeholders. These review sessions can be informal ‘show and tell’ sessions or more formal meetings. Sprint retrospective:  At the end of each sprint cycle, the team also meets to discuss what’s working (or not) on a process level, including blockers, communication issues, or a lack of resources. Product backlog refinement:  While not always listed as an ‘official’ ceremony, product bac...

  Here is a full list of the Agile team roles: 1.  Product owner   It manage the product roadmap and prioritize the backlog. They also define the product vision and manage stakeholders. They have the authority to make key decisions and in particular, are responsible for making sure the team is working on the right items. It is helpful for the product owner to be able to communicate effectively with stakeholders.  The Product owner should be able to understand what customers want and make adjustments accordingly. They can liaise between engineering and business teams, and they can offer insights to marketing and sales teams about the product if needed. 2.  Developer An Agile team consists of more than one developer, but these are the next essential role after the product owner. Developers will build your product, and they are responsible for programming, testing, and debugging the product.  3.  Scrum master It facilitate scrums- the Agile fram...

1. Less prone to error Waterfall relies heavily on initial requirements. However, if these requirements aren’t documented precisely, or there was a misunderstanding around the detail of what the customer wanted, it makes things very difficult. Not so with Agile – requirements are checked and confirmed throughout the project. 2. More flexible Once a step has been completed in Waterfall, it’s difficult to go back and make changes. In contrast, Agile builds a working version of the whole project ( an MVP ) so the customer can shape how it’s built. Seeing a working version early on in the project allows the customer to say ‘I like this, but I don’t like that’, and so shape the product according to their requirements. This is harder to do with Waterfall because the customer has to outline all their preferences upfront, without seeing a working version. 3. More predictable end product With Waterfall, the product is mainly tested at the end of the project. If the customer’s need...

 T he waterfall model has drawbacks, including its inflexibility and lack of revision opportunities. Some specific concerns include the following: Design flaws, when discovered, often mean starting over from scratch It doesn’t incorporate mid-process feedback from users or clients and makes changes based on results Delaying the   testing until the end of development is common There’s no consideration for error correction The model doesn’t accommodate changes, scope adjustments, and updates well Work on different phases doesn’t overlap, which reduces the efficiency Projects don’t produce a working product until later stages Not an ideal model to use for complex and high-risk projects

  GitHub is a code hosting platform for version control and collaboration. It lets you and others work together on projects from anywhere. GitHub essentials like repositories, branches, commits, and pull requests. You'll create your own Hello World repository and learn GitHub's pull request workflow, a popular way to create and review code.

  DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the software development lifecycle and provide continuous delivery with high quality. The benefits of following DevOps practices are numerous and can be felt throughout the organization. Faster and more reliable software delivery DevOps practices help teams to deliver software more frequently and with fewer defects. This is achieved by automating many of the tasks involved in the software development lifecycle, such as testing, deployment, and monitoring. Automation helps to reduce errors and improve the overall quality of software releases. Improved collaboration and communication DevOps breaks down the silos between development and operations teams, encouraging them to work together more closely. This collaboration leads to better communication and understanding between the teams, which can help to identify and resolve issues more quickly. Increased agility and responsivenes...

Continuous integration.  In the CI stage, developers write a feature, update or fix, then commit the code to a central code repository. Organizations often use version control tools  like GitHub and Atlassian Bitbucket. These tools enable developers to write or modify code without interrupting another developer's progress. The next phase involves the automation server, which triggers tests to run on the code. Configure the automation server to watch when a particular branch in the code repository receives a commit. The server should then pull down the code and kick off the pipeline, move code from successful tests to build automation, and so on. Jenkins is the most prolific automation server in the industry; others include Atlassian Bamboo, CircleCI, Travis CI and CloudBees CI. Continuous testing.  In the initial stage of the pipeline, static code analysis can check for syntax issues and common vulnerabilities. Use plugins in the CI server to configure static code an...
