A migration is a small file for one schema change. They live in your repo, run in order, are tracked in a table so the DB knows what's run, and often have an up and a down. Everyone ends up with the same schema. Using them yet, or hand-written SQL? #LearningInPublic

[FALCON 🖥️ @UgFalconX]

The problem migrations solve: the shape of your data changes over time (new tables, renamed columns, indexes). If those changes only happen by someone typing SQL by hand on one machine, every environment slowly drifts apart. #Databases

[FALCON 🖥️ @UgFalconX]

One sentence that cleared up a lot for me this week: if Git is version control for your code, database migrations are version control for your database structure. 💡 #LearningInPublic #Databases

Two people edit the same paragraph differently? Someone has to decide which wording wins. That's a merge conflict, just a decision Git can't make for you. And since main is often what gets deployed, keeping it reviewed matters. Your go-to Git analogy? #LearningInPublic

[FALCON 🖥️ @UgFalconX]

Happy with your draft? Hand it to a colleague and ask "can you check this before we update the real one?" That's a pull request. They comment, maybe ask for changes, and once it's approved your edits get folded into the original. That's the merge. #Git

The analogy that made branches click for me: drafting a document. ✍️ Your team has one shared, polished doc. That's main, and nobody scribbles on it directly. To change something, you photocopy it and scribble on the copy instead. That's a branch. #LearningInPublic #Git

[FALCON 🖥️ @UgFalconX]

More Git mistakes to dodge: working straight on main (branches are cheap, use one per feature or fix) and force pushing a shared branch, which can wipe out work others have already pulled. Fine on your own branch, risky on shared. What would you add? #LearningInPublic

[FALCON 🖥️ @UgFalconX]

Two Git habits worth breaking: giant "fixed stuff" commits that touch 40 files for five reasons (hard to review, hard to roll back), and vague messages like "update" or "wip". Small, focused commits with a line on what changed and why are much kinder. #Git

[FALCON 🖥️ @UgFalconX]

Git mistake I most want to avoid: committing secrets like API keys, passwords and .env files. Once pushed, assume they're compromised, as deleting the file later doesn't remove it from history. Add a .gitignore early, rotate any leaked key. #LearningInPublic #Git

[FALCON 🖥️ @UgFalconX]

Analogy that helped me: Git is your camera, GitHub is the online photo album. GitLab and Bitbucket do a similar job, and Git doesn't care where your remote lives. Commit talks to your machine, push talks to the remote. Did you mix them up too? #LearningInPublic

[FALCON 🖥️ @UgFalconX]

GitHub (@github) is a website that hosts Git repos online and adds a layer for working with others: a remote to push to and pull from, pull requests for review, issues for bugs and to-dos, and Actions for things like running tests. #GitHub

[FALCON 🖥️ @UgFalconX]

Easy mix-up when you're starting out: Git and GitHub aren't the same thing. 😅 Git is the tool. It tracks changes to your files, lives on your computer, works completely offline, and it's free and open source. #LearningInPublic #GitHub

[FALCON 🖥️ @UgFalconX]

Every Git commit saves a snapshot of your files, so you can see what changed and when, go back if something breaks, and try ideas on a branch. A good message tells future you why, not just what. What's one Git command you wish you'd learned sooner? #Git

[FALCON 🖥️ @UgFalconX]

New series: I'm learning backend development in public, mistakes and all, with the @roadmapsh backend roadmap as my guide. 🙂 First up is Git, easy to write off as "the thing you type before you push". It's a time machine for your project. #LearningInPublic #Git

What is a file system?

A file system is how an operating system organizes, stores, and retrieves data on a storage device.

It helps your computer manage files and folders, know where data is stored, and access it when needed.

Examples: FAT32, NTFS, ext4, and APFS.
