Learn the parts of software school skips.

A practical, late-night field guide to the stuff tutorials cut for time: Git, deployment, Docker, hosting, environment variables, CI/CD, DNS, logs, and how real apps are actually structured and shipped.

why this exists, a note from the maker

In my four years of undergrad I met plenty of people who could actually write the code — reverse a linked list, pass the LeetCode questions — but especially in those last two years, I noticed a severe lack of people who could actually set up a dev environment, debug, etc.

So the whole point of this site (other than the resume fluff) was making a cute little blog that reads a little better than your average documentation — which you wouldn't read anyways.

So if you're just getting started, or didn't pay attention in your web apps class, here's something for you.

Things nobody explained

Nine things you'll hit in your first real project. Each one is a channel you can tune into.

Git

version control, or time travel with consequences.

Deployment

the part after the build that no tutorial filmed.

Docker

it works in the container. so ship the container.

Environments

dev, staging, prod, and the one var you forgot.

CI/CD

robots that judge your commits, politely.

Hosting

where your app sleeps when the laptop closes.

DNS

the internet's address book. cached, mostly.

Logs & debugging

the black box recorder of your bad decisions.

Real app structure

where files go when 'it depends' is the only answer.
