Database do's and don'ts

This is a generic guidline that applies mostly to Ruby on Rails and Postgres, but can be usefull for running any database migrations in CI.

Using NGINX with Brotli

This Gist demonstrates enabling Brotli in Nginx in App Engine Flex using a custom container.

Running in Docker locally

Use of basic Nginx image adapting the example nginx.conf adapted from Full Example Configuration

docker run --rm -itd --name test-nginx \
  -v $(pwd):/usr/share/nginx/html:ro \

The 4 C's of good technical communication:

concise

Concision not only saves the audience time, it cuts out distracting verbiage and helps avoid burying key information in a sea of boiler plate.

Audiences very often revisit sources, and concision makes it easier to relocate particular bits of information.

Smaller pieces are easier to rearrange, and so in practice, the more concise, the more authors are likely to work out an ideal structure.

Installing Postgres via Brew

Pre-Reqs

Brew Package Manager

In your command-line run the following commands:

brew doctor
brew update

Cheat Sheets are greate but they are not a substitute for learning the framework and reading the documentation as we most certainly have not covered every potential example here. Please refer to the Rails Command Line Docs for more information.

Command Line Generator Info

Reference

You can get all of this information on the command line.

rails generate with no generator name will output a list of all available generators and some information about global options. rails generate GENERATOR --help will list the options that can be passed to the specified generator.

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.
