Presenters & Decorators

Decorators

Decorators are used to add new functionality to an already existing object by "wrapping" it with new methods, without effecting other instances of that object. Thus, decorators are a perfect example of the Open/closed principle, in which an object is "open for extension" but "closed for modification"; you should be able to add new behavior to application without changing it's underlying source code. If any of this is a bit hard to swallow, I would

(NOTE: Current and future versions of this and any other Advantage 2-related things I post will be at https://github.com/nicholasknight/adv2keyboard)

I received my Advantage 2 today. There's no full manual yet, even though keyboards are apparently arriving (hint, hint, Kinesis). The quick start guide leaves out the "power user mode", and there are some other quirks.

Update: A manual has been posted at http://www.kinesis-ergo.com/advantage2-resources/

It includes a dictionary for the key maps, but I know it leaves at least one possible key undocumented: it does not list f14, but I have successfully mapped my scrollock to f14 regardless.

It also mentions a firmware version (1.0.18) that doesn't seem to be available yet, with a new feature (status report playback speed).

1. rails new <project_name> -d postgresql --skip-turbolinks --skip-spring -T

• -d postgresql sets up the project to use PostgreSQL
• --skip-turbolinks & --skip-spring creates a project that does not use turbolinks or spring
• -T skips the creation of the test directory and use of Test::Unit

2. In the Gemfile:

• Available to all environments:
  • gem 'figaro' - store environment variables securely across your app (docs)
  • Uncomment gem 'bcrypt', '~> 3.1.7' if you will be hosting your own user accounts with passwords (docs)
• Inside of group :test:
  • gem 'rspec-rails' - user rspec in place of minitest (docs)

Iterators

What is the difference between forEach and map in JS?

forEach:

const arr = [1, 2, 3];

const eachExample = () => arr.forEach(e => e);
