How to deploy a Rails 7.1 app with Postgres and Kamal on a single server

I think you have looked at the tutorial from Mr. Heinemeier Hansson at least once or twice and have a similar setup.

rails new kamal_pg --css tailwind --skip-test --database=postgresql

cd kamal_pg

SETUP VPS

based on DigitalOcean guide

Create local project

local$ rails new appname -T -d postgresql
local$ rails g scaffold Story title:string body:text
local$ rails db:migrate

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

What's an Effective Engineer?

Originally published in June 2008

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.
