"Git Command Series: How to Use `git gc` for Cleanup"

It's crazy how much data is hidden inside our Git commit histories. Imagine if there was a tool that semantically analyses your code and based on the analyses is able to tell which functions are doing too much in terms of their meaning (imagine a function that does banking, invoicing, emailing and automated Slack notifications). Not only that but such a tool can also show you which parts of the given piece of code don't fit in that context (imagine a function where most of its lines are about real estate filtering but there's this one line that's checking if it's a birthday of one of the company employees today). Both of these mertrics are hinting at architectural issues which over time lead to higher tech debt which in turn leads to slower and more innefective development of new features and more and more complex fixing of bugs. Now if you run this tool on every file of your repository for every commit in your Git history what you get at the end is not only a graph pretty much showing you the progress of your tech debt but also who causes it and who fixes it. This can give invaluable insights that were wet dreams of project managers 10 years ago but could easily be a reality today. There are many more exciting things you can do with "simple" AST-based code embeddings - this is just the beginning. The programmers of the future won't be replaced by AI models but AI models will absolutely speed up things that are already possible and make possible things that are not yet possible today.

Git use කරද්දි ඉස්සර තිබුණ ලොකුම ප්රශ්නයක් තමා meaningful commit message එකක් type කරන එක 😅. හැබැයි දැන් Cursor, VS Code වගේ tools වලින් automatically commit messages හදලා දෙනවා 🤖✨. ඒත් මේ commit messages වලට “conventional commits” (https://lnkd.in/gUqCKdVA) කියලා standard එකක් follow කරන්න පුලුවන් කියලා දැනන් හිටියද? 🤯 Cursor නම් අපේ commit history එක බලලා conventional commits වලට adapt වෙනවා (https://lnkd.in/gGngsynt). Features, bug fixes, breaking changes, chores (maintenance) tasks වගේ දේවල් ලේසියෙන් categorize කරගන්න පුලුවන් මේකෙන් 🧩. ඒ වගේම release notes හදද්දි commit messages automatically use වෙලා ලස්සනට docs generate වෙනවා 📄✨. One of the biggest struggles I had when using Git was writing a meaningful commit message 😅. But now tools like Cursor and VS Code generate commit messages automatically 🤖✨. And these commit messages can even follow the “conventional commits” standard 🤯. Cursor adapts based on your own commit history too (https://lnkd.in/gGngsynt). It becomes super easy to categorize features, bug fixes, breaking changes, and maintenance tasks 🧩. And later, when generating release notes, those commit messages automatically help create clean, beautiful docs 📄✨. #Git #DevTools #CursorAI #ConventionalCommits #BuildInPublic

Day 20/30 of 30days30projects GitHub webhooks From manual deployments to AUTOMATED everything! Today I built a complete CI/CD pipeline that builds, tests, and deploys containers automatically on every git push! What I Built: A production-ready CI/CD pipeline using Jenkins with GitHub webhooks that automatically: - Detects code changes - Builds Docker images - Pushes to Docker Hub - Triggers deployments All happening in seconds after a simple `git push` Architecture Overview: GitHub → Webhook → Jenkins → Docker Build → Docker Hub → Deploy Every code commit triggers the entire pipeline automatically. No manual intervention needed! Key Components: GitHub Webhook Integration Real-time push notifications Automatic pipeline triggers Payload validation Secure webhook secrets # Jenkins Pipeline Declarative pipeline as code Multi-stage build process Automated testing Docker image building Registry authentication # Docker Hub Integration Automated image versioning Tag management (latest + version) Private repository support Image scanning ready # The Magic of Webhooks: Before: - Manual git pull - Manual docker build - Manual docker push - Manual deployment - Time: ~15 minutes After: - `git push` - Everything's deployed! - Time: ~2 minutes (automated) # Technical Stack: • Jenkins - CI/CD automation server • GitHub Webhooks - Event-driven triggers • Docker- Containerization • Docker Hub - Container registry • Groovy - Pipeline scripting • Git - Version control • Shell Scripts - Automation glue #30Days30Projects #Jenkins #CICD #Docker #DockerHub #DevOps #Automation #GitHubWebhooks #ContinuousIntegration #ContinuousDeployment #CloudComputing #Containerization #Microservices #AgileDevelopment #TechTwitter #BuildInPublic

If you want to master Git as a software engineer, learn these 10 commands. Most engineers know git add, git commit, git push. Here are the 10 commands that unlock everything else: 1. git worktree Run two Claude Code sessions without losing context. Creates a second folder on a different branch for urgent fixes while your main Claude keeps working. Example: git worktree add ../hotfix 2. git stash Save work with context you'll remember later. Future you won't remember what "WIP" meant. Example: git stash push -m "auth refactor" 3. git rebase Clean up messy commits before anyone sees. Turn "fix", "fix again", "oops" into one clean commit. Example: git rebase -i HEAD~3 4. git reset Undo last commit, keep all changes. Perfect for "committed too early" moments. Example: git reset --soft HEAD~1 5. git cherry-pick Copy one commit to your current branch. Move that critical fix without merging 47 other commits. Example: git cherry-pick a1b2c3d 6. git reflog Time machine for Git mistakes. Git remembers everything for 90 days. You can't lose commits. Example: git reflog 7. git bisect Find which commit broke things. 200 commits → 8 tests. Turns 2 hours into 10 minutes. Example: git bisect start, git bisect bad, git bisect good v2.0.0 8. git log Visualize your branch structure before merging or rebasing. Example: git config --global alias.tree "log --oneline --graph --all" 9. git diff Catch debug code before production. Shows what you're about to commit. Example: git diff --staged 10. git commit --amend --no-edit Add forgotten files to last commit. Only use before pushing. Example: git add file.js, git commit --amend --no-edit --- PS: I run a weekly newsletter for software engineers who want to build systems with AI: Get it here: https://lnkd.in/eQkMB_bz Repost ♻️ and follow Owain Lewis for more.

🚀 Most developers only use 5 Git commands… But there are at least 15 more that can save you hours of debugging, cleanup, and context switching. Here are some hidden gems every developer should know: 👇 1️⃣ git stash → Save your work-in-progress without committing. Switch branches safely. 2️⃣ git reflog → Recover “lost” commits. Your safety net when a reset goes wrong. 3️⃣ git bisect → Use binary search to find the exact commit that introduced a bug. 4️⃣ git rebase -i → Clean up your commit history. Squash, reorder, or edit before pushing. 5️⃣ git cherry-pick → Apply a specific commit from another branch — no full merge needed. 6️⃣ git diff --staged → Review what’s staged before committing. Catch mistakes early. 7️⃣ git commit --amend → Fix your last commit message or add forgotten files. 8️⃣ git reset HEAD~1 → Undo your last commit but keep the changes locally. 9️⃣ git clean -fd → Remove untracked files and folders. Start fresh instantly. 🔟 git log --oneline --graph → Visualize commit history — branches, merges, everything. 1️⃣1️⃣ git blame → See who last modified each line. Great for debugging (not blaming 😉). 1️⃣2️⃣ git show → View full details of any commit — code changes and metadata. 1️⃣3️⃣ git remote -v → List all remote repositories and URLs. Know where you’re pushing. 1️⃣4️⃣ git fetch --prune → Clean up deleted remote branches and stay in sync. 1️⃣5️⃣ git diff branch1..branch2 → Compare two branches side by side. 💡 These commands don’t just make you faster, they make you safer and more confident when working with Git. 👉 What’s one underrated Git command you can’t live without?

🚀 **Day 41: Git Command Spotlight** 🚀 Ever found yourself preparing for a code review and wondering "What files did I actually change in my recent commits?" Here's your solution: `git diff --name-only HEAD~3..HEAD` This powerful command shows you exactly which files were modified in your last 3 commits - perfect for getting that bird's eye view before presenting your work! 📋 **🎯 Use Cases:** **Beginner:** You've been working on a feature branch and want to see all the files you've touched before creating a pull request `git diff --name-only HEAD~2..HEAD` **Pro Level 1:** Preparing release notes and need to identify which configuration files were modified across multiple commits `git diff --name-only --diff-filter=M v2.1.0..HEAD | grep config` **Pro Level 2:** Analyzing the scope of changes for impact assessment before deployment `git diff --name-only HEAD~10..HEAD | xargs wc -l | sort -nr` **💡 Pro Tip to Remember:** Think "HEAD minus commits" - HEAD~3 means "3 commits back from current HEAD". The ".." is your range operator saying "from here to there" **🔍 Common Use Cases:** ✅ Code review preparation ✅ Change impact analysis ✅ Release planning ✅ Merge conflict prevention What's your go-to git command for code reviews?
