Simple bijective function (base(n) encode/decode)
# Simple bijective function
# Basically encodes any integer into a base(n) string,
# where n is ALPHABET.length.
# Based on pseudocode from http://stackoverflow.com/questions/742013/how-to-code-a-url-shortener/742047#742047
ALPHABET =
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split(//)
# make your own alphabet using:
# (('a'..'z').to_a + ('A'..'Z').to_a + (0..9).to_a).shuffle.join
def output name=((default=true); "caius")
puts "name: #{name.inspect}"
puts "default: #{default.inspect}"
end
output
# >> name: "caius"
# >> default: true
output "avdi"

A proof that Promises/A is a Monad
//-------------------------------------------------------------
//
// Hypothesis:
//
// Promises/A is a Monad
//
// To be a Monad, it must provide at least:
// - A unit (aka return or mreturn) operation that creates a corresponding
// monadic value from a non-monadic value.
// - A bind operation that applies a function to a monadic value

Guide to the Router Facelift

Ember Router Async Facelift

The Ember router is getting number of enhancements that will greatly enhance its power, reliability, predictability, and ability to handle asynchronous loading logic (so many abilities), particularly when used in conjunction with promises, though the API is friendly enough that a deep understanding of promises is not required for the simpler use cases.

import ApplicationAdapter from './application';
import BulkOperations from 'ted-ed-lesson-creator/mixins/bulk-operations';
export default ApplicationAdapter.extend(BulkOperations, {
bulkCollectionName: 'item', // used to build the endpoint, in this case becomes /items
bulkOperations: ['PUT', 'POST']
});
