Good explanation of ruby object model -- mainly, 'classes are objects'?

fixed the issue. Will look into that further It means precisely what it sounds like — classes are objects. Specifically, they are instances of the class Class, which is itself a subclass of the class Module, which in turn is a subclass of Object, just like every other class in Ruby. Like any other object in Ruby, a class can respond to messages, have its own instance variables, etc.
As a practical example, let's take private.
code :


Share : facebook icon twitter icon

it fixes the issue Ruby on Rails follow linguistic convention. That means a model represents a single user, whereas a database table consists of many users.

Does that help I'm working with a database that has a lot of linked model objects and I'm wondering, if I have a model object called "User" and users can have "Applications" linked to them, what is the easiest way to get the array of all Applications linked to a given array of Users?
code :
@applications = @users.map(&:applications)

this one helps. Looks like a typo. Can you change the input parameter's name to "driver" in following constructor:
code :
public Opentaskpage(WebDriver drier){
PageFactory.initElements(driver, this);

What is a good explanation for the C++11 memory model?

Does that help Different instructions use different parts of the processor. Modern super-scalar processors are able to execute multiple instructions simultaneously, as long as they use different resources (from a single thread, I am not referring to multicore). So the CPU will actually go looking forward in the instruction stream for an instruction it can start working on at the same time as the current one (due to pipelining and branch prediction, instructions are decoded quite a while before they execute, which makes this look-ahead possible).
The CPU is careful to respect data dependencies, meaning that if one instruction uses the result of another, they will execute in the right order. But if for example two instructions write two different memory locations, and the first one can't start because it's waiting for say an integer division unit to become available, the memory write from the "later" instruction could actually happen first.
