• iPad/iOS – full page redraws

iOS devices do a full-page redraw when we introduce new height at the bottom of the page or when backgrounding/foregrounding the browser. How to avoid that?

• Jasmine not working when run through jenkins

Jasmine:ci on firefox fails on CI only with the error:

/home/ci/.rvm/gems/ruby-1.9.3-p194@gemini/gems/selenium-webdriver-2.25.0/lib/selenium/webdriver/remote/response.rb:52:in `assert_ok’: ReferenceError: jsApiReporter is not defined (Selenium::WebDriver::Error::JavascriptError)

Anyone seen this? It runs great on the command line when we ssh into the ci box, but fails when run through Jenkins.

• JS – objects on prototypes

In javascript, if you give a prototype an object property, then mutating that object will do so for all instances of the class.

So if you do this:

MyClass.prototype.things = {
  "foo": "cool"
};

var instance1 = new MyClass(),
instance2 = new MyClass();

instance1.things["bar"] = 5;

then

instance2.things["bar"] === 5
