Chess - Piece Activity Resources

Piece activity is everything in a chess game

Activity of our pieces is a primary goal in chess, but newer players commit lots of mistakes around this theme. By GM Irina Krush

Grand Master RB Ramesh - Learn Chess the right way! - Improving pieces

In this live stream video, I explain the concept of "active" and "passive" pieces. Under what circumstances a piece becomes passive, how to identify a passive piece, how to improve the position of passive pieces are explained with examples in this video. By GM RB Ramesh

  class << self
    def meet(person, &block)
      yield person
    end

 # Greet everyone except Johnny

A small sampling of external projects initially built for Ember use but designed to be used standalone:

• Handlebars - templating engine
• simple-html-tokenizer - an HTML5 tokenizer
• HTMLBars - alternate HTML-aware Handlebars backend
• morph - text-node placeholders for data binding systems
• RSVP - fast, lightweight promise library
• route-recognizer - just the recognition part of a router
• router.js - hierarchical states and transition-based router
• dag-map - graph library

Better Jasmine Tests With this

On the Refinery29 Mobile Web Team, codenamed "Bicycle", all of our unit tests are written using Jasmine, an awesome BDD library written by Pivotal Labs. We recently switched how we set up data for tests from declaring and assigning to closures, to assigning properties to each test case's this object, and we've seen some awesome benefits from doing such.

The old way

Up until recently, a typical unit test for us looked something like this:

describe('views.Card', function() {

ActiveSupport::Notifications.subscribe('deprecation.rails') do |name, start, finish, id, payload|
  Honeybadger.notify(
    error_class:   "DEPRECATION WARNING",
    error_message: payload[:message],
    backtrace:     payload[:callstack]
  )
end
