⚠️ This discussion applies to version 1.13 (released 2019) of the Go language.

Why are Go's identical errors not equal?

Or, more precisely, why are two separate but otherwise seemingly identical errors created by Go's errors.New function not equal according to the == operator?

Consider the output of the following small program (Go Playground link) which compares Go's error values for equality:

package main

Guide for developing Vue.js applications.

v. 0.0.1

Vue.js is an amazing framework, which can be as powerful as Angular or React, the two big heavy hitters in the world of front-end frameworks.

However, most of Vue's ease-of-use is due to the use of Observables - a pattern that triggers re-renders and other function calls with the reassignment of a variable.

cors.py for mitmproxy

Hacking CORS restriction to enable in-browser XHR to any server.

Usage

Say you are running an web app at localhost, and you want to send XHR to http://remote-server:80, but the CORS restriction forbids access because you are sending requests from an origin that remote-server:80 does not allow.

Run:

	provider "aws" {
	version = "~> 2.0"
	region = "eu-west-2"
	}

	# Providing a reference to our default VPC
	resource "aws_default_vpc" "default_vpc" {
	}

	# Providing a reference to our default subnets

	export function magicMethods (clazz) {
	// A toggle switch for the __isset method
	// Needed to control "prop in instance" inside of getters
	let issetEnabled = true

	const classHandler = Object.create(null)

	// Trap for class instantiation
	classHandler.construct = (target, args, receiver) => {
	// Wrapped class instance

	#!/usr/bin/ruby
	#
	# Usage:
	# ruby ./merge_dna_files.rb file,file1,file2... > merged_file.txt
	#
	# Example:
	# ruby ./merge_dna_files.rb AncestryDNA.txt genome_John_Doe_v4_Full_20170428065226.txt > merged_raw.txt
	#
	# Supports 23andMe, AncestryDNA, and Genes for Good 23andMe compatible file formats.
	# The result will be in 23andMe file format.
