jq: JSONL ↔︎ JSON conversion

Prerequisites

jq — https://jqlang.org/ — "like sed for JSON data"

There are several options available for installing jq. I prefer to use Homebrew: brew install jq
JSONL → JSON

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

query
mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.

Thoughts about Rails Presenters

This is a collection of links, examples and rants about Presenters/Decorators in Rails.

The "Decorator" pattern slowly started gaining popularity in Rails several years ago. It is not part of core Rails, and there's many different interpretations about how it should work in practice.

Jay Fields wrote about it in 2007 (before he switched back to Java and then Clojure): http://blog.jayfields.com/2007/03/rails-presenter-pattern.html

Git Submodules - Basic Explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a sub-repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

Separate big codebases into multiple repositories.

	{
	"context": "Editor",
	"bindings": {
	"alt-up": "editor::SelectLargerSyntaxNode",
	"alt-down": "editor::SelectSmallerSyntaxNode",
	"ctrl-cmd-up": "editor::MoveLineUp",
	"ctrl-cmd-down": "editor::MoveLineDown"
	}
	}

	# gem install mechanize
	require 'mechanize'

	class Download

	def initialize(site, email, pass)
	@options = {site: site, email: email, pass: pass}
	end

	def call

	#!/usr/bin/env bash
	# vim: set filetype=ruby:
	# b - browse Chrome bookmarks with fzf

	[ $(uname) = Darwin ] \|\| exit 1
	which fzf > /dev/null 2>&1 \|\| brew reinstall --HEAD fzf \|\| exit 1

	awk 'BEGIN { FS = "\t" } { print $2 }' \|

	require 'rails_helper'

	RSpec.describe TodosController, :type => :controller do

	describe "GET #index" do
	#describe "POST #create" do
	#describe "GET #show" do
	#describe "PATCH #update" do (or PUT #update)
	#describe "DELETE #destroy" do
