Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Manage services in systemd, openRC and runit

systemd

list all services: systemctl list-unit-files
list running services status: systemctl list-units
list failed services: systemctl --failed
list available services: systemctl --all
start a service: systemctl start [SERVICE_NAME]
stop a service: systemctl stop [SERVICE_NAME]

QueryExtensions

First, you'll need to incorporate the extension:

class ApplicationRecord < ActiveRecord::Base
  extend QueryExtensions
end

Arel Cheatsheet on Steroids

A (more) complete cheatsheet for Arel, including NamedFunction functions, raw SQL and window functions.

Tables

posts = Arel::Table.new(:posts)
posts = Post.arel_table # ActiveRecord

Table alias

Vue: Pass Slots through from Parent to Child Components

The Situation

We've got some components A, B and C which provide different slots.

const A = {
  template: `<div><slot name="a">Default A Content</slot></div>`
}

const B = {

Faster Rails tests

Feedback loop speed in one of the biggest contributing factors to overall development time. The faster you get results, the faster you can move on to other things. A fast enough test suite is therefore critical to teams' success, and is worth investing some time at the beginning to save in the long run.

Below is a list of techniques for speeding up a Rails test suite. It is not comprehensive, but should definitely provide some quick wins. This list of techniques assumes you're using minitest, but most everything should translate over to rspec by simply replacing test/test_helper.rb with spec/spec_helper.rb.
