When receiving JSON data from other resources(server API etc), we need Json.Decode to convert the JSON values into Elm values. This gist let you quickly learn how to do that.

I like to follow working example code so this is how the boilerplate will look like:

import Graphics.Element exposing (Element, show)
import Task exposing (Task, andThen)
import Json.Decode exposing (Decoder, int, string, object3, (:=))

Sonic Pi 2.2 at Bett 2015

This is a summary of a talk given at Bett 2015 on Sonic Pi

I started by playing excerpts from two programs, Scott Joplin Maple Leaf Rag, and a Percussion Generator, to illustrate different things Sonic Pi can do, and gave a brief description of Sonic Pi and the user interface, similar to section 1.2 of the built in tutorial, which is accessed by clicking the Help button.

I also showed how one of the example programs "Idm Breakout" could be copied and played. Then I used the following program sections to develop a code to play the round Frere Jaques

#Mounting Raspberry Pi Drive via Vagrant

Install Vagrant

Find instructions here Vagrant. Probably not a bad idea to run the getting started and make sure it works.

Identify your USB device

With your pi drive mounted (e.g. via a microsd reader) run VBoxManage list usbhost. This will print a list of UDB devices available to VirtualBox. Look for one that matches your device, this will probably have a manufacturer name of "Generic". Once you find it, note the VendorId and ProductId.

Configure Your Vagrant Project

Make a new directory and run vagrant init. This will create a Vagrantfile. Open this in a text editor and replace everything with this:
