Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)

Squashing Git Commits

The easy and flexible way

This method avoids merge conflicts if you have periodically pulled master into your branch. It also gives you the opportunity to squash into more than 1 commit, or to re-arrange your code into completely different commits (e.g. if you ended up working on three different features but the commits were not consecutive).

Note: You cannot use this method if you intend to open a pull request to merge your feature branch. This method requires committing directly to master.

Switch to the master branch and make sure you are up to date:

module Shopify.Product.Model where

type alias Product =
  { created_at : String,
    id : Int,
    product_type : String,
    published_at : String,
    published_scope : String,
    title : String,
    updated_at : String,

# And, to activate, you need to tell Rails to load it up:

Font Face

A mixin for writing @font-face rules in SASS.

Usage

Create a font face rule. Embedded OpenType, WOFF2, WOFF, TrueType, and SVG files are automatically sourced.

@include font-face(Samplino, fonts/Samplino);

We develop locally on MacOS. Due to some issues with cross compilation, we build the crystal binary on docker locally,
then zip that up and ship that along with the docker stuff to elasticbeanstalk.
