Most people use Git. Very few understand why it’s so efficient. Here’s the short explanation 👇 🧠 Git = content-based system It doesn’t store files. It stores snapshots (via hashes) Same content? → Stored once. No duplication.(deduplication) ⚙️ What happens in a commit? git commit -m "update" Behind the scenes: • Blob → file content • Tree → folder structure • Commit → snapshot + metadata Everything linked with hashes 🔗 📦 Why Git stays fast • Packfiles → bundle objects • Delta compression → store only changes Change 1 line? Git stores just that. Not the whole file. !! Without this the repose just explode !! 🔧 Hidden layer (most ignore) • Porcelain → git add, git push • Plumbing → actual engine Try this once 👇 echo "hello" | git hash-object -w --stdin You just created a Git object manually. If you understand internals → branching, rebasing, debugging becomes easy. 💡 Insight Git isn’t storing history… It’s storing connected snapshots 📚 Quick refs: https://lnkd.in/gSeM2kmA https://lnkd.in/gEMefujR Git becomes powerful the moment you stop memorizing… and start understanding ⚡ 👉 What part of Git still feels confusing to you? #Git #DevOps #Engineering #Backend — Abhishek Singh Chauhan

🚀 Today I learned: How to revert only specific files from a bad Git commit Earlier today, I made a mistake while working on a feature branch — I accidentally overwrote 31 important "workflow.json" files across two folders. The tricky part? I also had valid changes in the same branch that I needed to keep. A normal "git revert" would undo everything - good and bad. That’s when I discovered a much cleaner approach: a surgical revert that restores only the files you choose. Here’s the simple workflow I followed 👇 🔍 1. Find commits that touched the files git log --oneline -- 'path/to/folder/**/file.json' This filters history so you can quickly spot where things went wrong. 👀 2. Peek at file content from any commit git show <commit-id>:path/to/file.json No checkout needed — just inspect the file as it existed in the past. 📂 3. List exactly which files a bad commit changed git diff-tree --no-commit-id --name-only -r <bad-commit> -- 'path/**/*.json' This gave me a precise list of the 31 affected files. ♻️ 4. The magic command — restore only those files git checkout <good-commit-or-branch> -- file1 file2 file3 ... This pulls back only the selected files — everything else stays untouched. ✨ ✅ 5. Verify before committing git status --short git diff --cached I used to worry about “messing up Git,” but moments like this made me realize - Git is actually very forgiving when you know the right tools. If you're learning Git, this is a skill that will save you hours someday. #Git #SoftwareEngineering #LearningInPublic #DeveloperTips #VersionControl

Demystifying Git: The 4 Core Layers of Git. Most developers treat Git like a magic undo button, but understanding its actual internal architecture completely changes how you use it.These are the 4 core layers of git. • Persistence: Git is a key-value store. Every file (blob), directory (tree), Annotated Tag and commit is saved as an immutable object in .git/objects identified by a unique SHA-1 hash. • Content Tracker: Git tracks complete snapshots of your content, not file differences. These snapshots are maintained by a Tree object, which is dynamically generated from the index file (staging area) at the moment of commit. • Version Control: Git connects your snapshots into a timeline structured as a Directed Acyclic Graph (DAG). The Commit object acts as a node in this graph, storing metadata to link a specific snapshot to its parent history. • Distributed Version Control: Git is peer-to-peer. Every local clone is a fully autonomous backup of the entire project, and network operations (push/fetch) merely sync missing objects and update pointers. Branches, Head and tags aren't duplicated folders; they are like simply lightweight pointers to a commit within the DAG, making branching an instantaneous pointer swap. These insights are heavily inspired by the teachings of Mohit Dharmadhikari at VoidInfinity Tech. #Git #SoftwareEngineering #SystemArchitecture #DistributedVersionControl

Git isn’t slow — our understanding of it often is. Recently came across “High Performance Git” by Ted Nyman, and it reframes Git not as a simple VCS, but as a set of layered systems: a content‑addressed database, a filesystem cache, a graph walker, and a transfer protocol — each with its own performance trade‑offs. What stood out to me: - Git slowness usually isn’t accidental — it’s a result of how history traversal, refs, indexes, and packfiles interact at scale - Features like sparse checkout, commit‑graphs, partial clone, and maintenance aren’t “advanced tricks” anymore — they’re table stakes for large repos - Debugging Git performance requires instrumentation and diagnosis, not guesswork or folklore If you work with monorepos, CI pipelines, or large teams, this is a reminder that Git performance is a systems problem, not just a developer gripe. Curious: What’s the most painful Git performance issue you’ve run into at scale — and how did you fix it (or work around it)? 🔗 https://lnkd.in/grY9Xdhw #Git #DeveloperExperience #DevTools #SoftwareEngineering #Monorepo #CI #Productivity

Ever needed to switch branches… but your code isn’t ready to commit? 👀 That’s where git stash helps. It saves your current work (staged + modified tracked changes) and resets everything back to HEAD, so you can safely switch branches without committing incomplete code. Your stashes are stored like a stack (stash@{0} is the latest), and you can reuse them anytime. By default, only tracked files are saved: Add untracked files → git stash push -u Add ignored files → git stash push -a When you’re ready to continue: git stash apply → bring changes back (keep stash) git stash pop → bring changes + remove stash Need a specific one? git stash apply stash@{N} Want your staged changes back too? git stash apply --index git stash pop --index Manage everything easily: Save → git stash push -m "message" View → git stash list Inspect → git stash show -p stash@{N} Delete → git stash drop stash@{N} or git stash clear Think of it as putting your work on pause without losing a thing. 👉 Follow for more practical dev tips! #Git #GitHub #WebDevelopment #DevTips #Developers #Syncfusion

The most underrated Git skill: building your own tooling. A script I run every morning before standup: #!/bin/bash git log \ --since="yesterday" \ --author="$(git config user.name)" \ --format="%C(yellow)%h%Creset %s %C(dim)(%ar)%Creset" \ --no-merges As an alias: git config --global alias.standup \ "!git log --since=yesterday --author=$(git config user.name) --oneline --no-merges" And a quick repository health check: #!/bin/bash echo "=== Commits (last 30 days) ===" git log --since="30 days ago" --oneline | wc -l echo "=== Top contributors ===" git log --since="30 days ago" --format="%an" | sort | uniq -c | sort -rn | head -5 echo "=== Most changed files ===" git log --since="30 days ago" --name-only --format="" | sort | uniq -c | sort -rn | head -5 echo "=== Latest tag ===" git describe --tags --abbrev=0 2>/dev/null || echo "(no tags)" Save as ~/bin/git-health. Run monthly. The principle: Every time you type the same Git sequence more than three times in a week, turn it into a script or alias. 📚 Chapter 28 of Stop Breaking Git.

My git config grew over years. After a recent round of improvements I decided to write about it :) Five settings that made the biggest difference: rerere.enabled = true — Git records how you resolved a conflict. Same conflict again? Applied automatically. The sleeper hit most people don't know exists. rebase.autoSquash + autoStash + updateRefs — three settings that turn rebase from a ceremony into a one-liner. No manual stashing, automatic fixup folding, and all stacked branches move together. core.fsmonitor + untrackedCache — git status drops from hundreds of milliseconds to near-instant on large repos. A filesystem watcher replaces full directory scans. merge.conflictstyle = zdiff3 — conflict markers show three versions: yours, theirs, and the original. Once you see the common ancestor, the default style feels blind. push.autoSetupRemote + followTags — first push on a new branch, just git push. Tags travel with the code. No more -u origin branch-name, no more forgotten --tags.

Git worktrees have been in Git since 2015. I only really started using them this year. AI is why. One repo, multiple directories, each checked out to its own branch. Two or three branches open in parallel, all sharing the same .git. No stashing, no context-switching friction. What made it click: running multiple Claude Code sessions in parallel. If they share a working directory, they fight over the files. Give each session its own worktree and they don't. One session works a PRD milestone. Another investigates a regression. A third explores a risky refactor. Switching between them is just switching terminal tabs. And the throwaway angle is huge. AI can refactor aggressively: ten commits, half your files renamed, three new abstractions you didn't ask for, all in 30 minutes. If that lands on main, untangling is painful. If it's in a worktree, you git worktree remove and it's gone. Wrote about two layouts, my aliases, and how I actually use them with AI day to day: https://lnkd.in/dTGzTFT4
