Why Structure and Interpretation of Computer Programs matters

Brian Harvey University of California, Berkeley

In 2011, to celebrate the 150th anniversary of MIT, the Boston Globe made a list of the most important innovations developed there. They asked me to explain the importance of SICP, and this is what I sent them:

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, (:=))

import Http

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
