The use of a Using block is recommended good practice when using an object that Implements IDisposable

Basic HTTP calls don't provide code-reusability, however. And they can get confused with all the other features you're trying to implement. For those reasons, it's common to implement an API wrapper.
Foo = {
identify: function(input){
return Http.get('http://foo.net/api/identify/' + input...
After creating an API wrapper, it's likely that you may want to create an Atmosphere package to redistribute it and share it between applications. The files of your package will probably look something like this.
packages/foo-api-wrapper/package.js
packages/foo-api-wrapper/readme.md
packages/foo-...
Now that we have all those pieces put together, you should now be able to make calls like the following from within your app:
Foo.identify('John');
Foo.record_action_on_item('view', "HackerNews');
Obviously you'll want to adjust function names, arguments, urls, and the like, to create the ...
If we want something a bit more polished, with an integrated Dropzone UI and a REST endpoint, we're going to need to start adding custom REST routes and packages with UI helpers.
Lets begin by importing Iron Router and Dropzone.

As well as being able to create an array by filtering out nil from the transformed elements of a sequence, there is also a version of flatMap(_:) that expects the transformation closure to return a sequence S.

To be exact even rails is nothing more than a gem. A lot of gems are built on rails or other gems (they are dependent of said gem) or are standalone.

If you're writing a class that manages resources, you need to implement all the special member functions (see Rule of Three/Five/Zero). The most direct approach to writing the copy constructor and assignment operator would be:
person(const person &other)
: name(new char[std::strlen(other.n...
