Elm is not a frontend framework.
Elm is neither V in MVC, nor MV in MVC, nor even MVC itself.
You don't assemble libraries and configure options to make Elm do what you want.

Elm is a language. You write programs with it.

But instead of providing a regular main function to run, Elm wants you to write at least 2 parts to run your program: init and update. This is my pseudo code for your init and update plugs into Elm runtime:

let [globalState, cmd] = init(optionFlags)

Be Careful with Table Driven Tests and `t.Parallel()`

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

Remote GPIO

GPIO Zero allows you to create objects representing GPIO devices. As well as running it on a Raspberry Pi, you can also install GPIO Zero on a PC and create objects referencing GPIO pins on a Pi over the network.

To do this, you'll need to do a few things to get set up:

Enable Remote GPIO on the Pi in the Raspberry Pi Configuration Tool.
Run the pigpio daemon on the Pi:

	package gosumtype

	import (
	"time"
	)

	// To define this sum type:
	//
	// type User
	// = Anonymous

	FROM golang:1.12.5-alpine3.9 as builder
	RUN apk --no-cache add tzdata
	COPY . /src
	RUN go build -o /bin/timenow /src/timenow.go


	FROM scratch
	COPY --from=builder /bin/timenow /bin/timenow
	# without these, TZ env is useless
	COPY --from=builder /usr/share/zoneinfo /usr/share/zoneinfo

	import os
	import base64
	import SocketServer
	import BaseHTTPServer
	import SimpleHTTPServer

	class AuthHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
	''' Main class to present webpages and authentication. '''
	def do_AUTHHEAD(self):
	self.send_response(401)

	package main

	//implements the SFTP Service. Needs to be installed and managed using NSSM.

	import (
	"encoding/json"
	"io/ioutil"
	"log"
	"net/http"
	"os"

	docker logs nginx 2>&1 \| grep "127."
