Working a Purescript Exercise (sums)
View possibleSumsJourney.md

Introduction

This exercise shouldn't have been that challenging, but it stumped me. Here's my woeful journey with the path through it so that I can review my approach when I get stuck on the next exercise.

The Exercise

Found in the Purescript Book, exercise 2:

(Medium) Write a function possibleSums which uses foldM to determine all possible totals that could be made using a set of coins. The coins will be specified as an array which contains the value of each coin. Your function should have the following result:

Driving Instructions to Orphanage from Dianne's House

These instructions can be accessed two ways:

  • As a paper handout; see Dianne.
  • As a PDF file in your smart phone. The iPhone, for one, has iBooks which can hold a PDF file in your smart phone's memory and access it. Once loaded, you don't have to have a live Internet connection; this is handy when you want to turn off access in México to avoid (expensive!) roaming charges.

Opal can't seem to find Cucumber gem.
View opal_no_find_cuke_gem.md

I'm trying to spike running Cucumber in Opal; it's not find it, and I don't know why.

Here's my app/application file. The only change is the addition of the last 3 lines:

# when using sprockets/rails, we must include the corelib
require 'opal'

[1, 2, 3].each { |a| puts a }
You can’t perform that action at this time.
