Git basic introduction

What is GIT?
Git is the most popular version control system. Git tracks the changes you make to
?les, so you have a record of what has been done, and you can revert to speci?c
versions should you ever need to. With version control system, we can track software
development history and also can easily do collaborative work.

Git As a Distributed Version Control System

Local Repository Work?ow
Repository (��Repo��) is object database of the project, storing everything
needed from the project such as ?le, folder, version, history of commits,
deletions, etc

Local Repository Work?ow
Index - Files that have been changed, added and deleted will be staged
within the index until you are ready to commit the ?les. To see what is set in
your Git index, run git status within your repository
Head - a reference variable used to denote the most current commit of the
repository in which you are working
git add <filename>
git add *
git commit -m "Commit message"

Remote Repository Work?ow
git remote add origin <server>
git push origin master

Branching Command
git checkout -b <branch-name>
git checkout <branch-name>
git branch -d feature_x
git push origin <branch>
Create new branch
Switch to spesi?c
branch
Delete branch
Push branch to
remote repo

Update and Merge
git pull
git merge <branch>
git add <filename>
git diff <source_branch>
<target_branch>
Update Git
Merge another branch to
current branch
Add merged ?le
Check con?ict

Merging Best Practice (Especially for production stage)
�� Merge Origin/master to your branch ?rst
�� Resolve con?ict in your branch and make sure all code works well (tips: do
sanity check)
�� push merged code in your branch
�� switch to master branch
�� merge the prev mergered code to master (in this merge state, there is no
con?ict will occur because all con?ict already solved in prev merge)

Replace local changes (In case did something wrong)
git checkout -- <filename>
git fetch origin
git reset --hard origin/master
Replace ?le with last content
in HEAD
Drop all local
changes and
fetch from latest
remote repo

Git is a distributed version control system that allows developers to work together and track changes to code over time. It keeps track of changes by taking snapshots of the project that create unique IDs for each change. Developers can have their own copy of a repository and commit changes locally before pushing them to a remote server for others to access. This allows for non-linear development with features like branching and merging. GitHub is a popular site for hosting Git repositories online, but Git can also be used locally or with self-hosted servers.

Git is a distributed version control system created by Linus Torvalds to manage changes to the Linux kernel. It allows developers to work independently and merge changes later. Git uses local repositories that can act as both clients and servers, avoiding the need to be connected to a central server. The basic Git workflow involves modifying files in the working directory, staging changes, and committing snapshots of the staged changes to the local repository. Common Git commands are used to add, commit, push, pull, branch, merge, and more. Key features of Git include being open source, distributed, providing security and speed, supporting non-linear development with branching and merging, and assuring data integrity.

Git is a version control system that records changes to files over time, allowing users to recall specific versions. It is a distributed system where each local repository has a full copy of the project files and history, allowing offline work. Users can clone repositories locally or remotely. Files are added and committed with messages to save snapshots, and commits can be visualized. Changes are pushed to remote repositories to share work, and branches allow independent lines of development that can be merged together. Tags mark important commits, and errors can be fixed by resetting files or the repository state.

Java on AWS Without the Headaches - Fast Builds, Cheap Deploys, No KubernetesVictorSzoltysek

Java Apps on AWS Without the Headaches: Fast Builds, Cheap Deploys, No Kubernetes Let��s face it: the cloud has gotten out of hand. What used to be simple��deploying your Java app��has become a maze of slow builds, tedious deploys, and eye-watering AWS bills. But here��s the thing: it doesn��t have to be this way. Every minute you spend waiting on builds or wrestling with unnecessary cloud complexity is a minute you��re not building the features your customers actually care about. In this talk, I��ll show you how to go from a shiny new Java app to production in under 10 minutes��with fast builds, cheap deploys, and zero downtime. We��ll go deep into optimizing builds with Gradle (it��s time to leave Maven in the dust), parallelization strategies, and smarter caching mechanics that make your CI/CD pipelines fly. From there, we��ll review the dozen+ ways AWS lets you deploy apps and cut through the chaos to find the solutions that work best for lean, fast, cost-effective pipelines. Spoiler: ECS and EKS usually aren��t the answer. Oh, and I��ll even show you how AI tools like AWS Bedrock can help streamline your processes further, so you can automate what should already be automatic. This talk is for developers fed up with the cost, complexity, and friction of modern cloud setups��or those who long for the simplicity of the Heroku/Beanstalk/PCF days when deploying to the cloud wasn��t a headache. Whether you��re on AWS, Azure, or GCP, you��ll learn actionable, cloud-agnostic tips to build faster, deploy cheaper, and refocus on what matters most: delivering value to your users.

When Platform Engineers meet SREs - The Birth of O11y-as-a-Service SuperpowersEric D. Schabell

Monitoring the behavior of a system is essential to ensuring its long-term effectiveness. However, managing an end-to-end observability stack can feel like stepping into quicksand, without a clear plan you��re risking sinking deeper into system complexities. In this talk, we��ll explore how combining two worlds��developer platforms and observability��can help tackle the feeling of being off the beaten cloud native path. We��ll discuss how to build paved paths, ensuring that adopting new developer tooling feels as seamless as possible. Further, we��ll show how to avoid getting lost in the sea of telemetry data generated by our systems. Implementing the right strategies and centralizing data on a platform ensures both developers and SREs stay on top of things. Practical examples are used to map out creating your very own Internal Developer Platform (IDP) with observability integrated from day 1.
