A method called in one object will move up the chain of objects until one is found that can properly handle the call. This particular example uses scientific experiments with functions that can just get the title of the experiment, the experiments id or the tissue used in the experiment.

Headers are a crucial consistency checking mechanism, but they should be
as small as possible.
In particular, that means that a header should not include other headers
just because the implementation file will need the other headers.
A header should contain only those headers necessary for a con...
Let's pick as an example a function that takes 2 Map and return a Map containing every element in ma and mb:
def merge2Maps(ma: Map[String, Int], mb: Map[String, Int]): Map[String, Int]
A first attempt could be iterating through the elements of one of the maps using for ((k, v) <- map) and so...

You can add a method to any class in Ruby, whether it's a builtin or not. The calling object is referenced using self.
class Fixnum
def plus_one
self + 1
end
def plus(num)
self + num
end
def concat_one
self.to_s + '1'
end
end
1.plus_one # => 2
3.plus(5) ...
Classes may be defined using a .classname syntax:
Code:
a.button
Result:
<a class="button"></a>
Since div's are such a common choice of tag, it is the default if you omit the tag name:
Code:
.content
Result:
<div class="content"></div>
IDs may be defined using a #idname syntax:
Code:
a#main-link
Result:
<a id="main-link"></a>
Since div's are such a common choice of tag, it is the default if you omit the tag name:
Code:
#content
Result:
<div id="content"></div>
Lets say you have a simple ApiController like this:
[HttpGet]
[Route("test")]
public dynamic Test()
{
dynamic obj = new ExpandoObject();
obj.prop1 = "some string";
obj.prop2 = 11;
obj.prop3 = "another string";

Swarm Mode Node Availability:
Active means that the scheduler can assign tasks to a node.
Pause means the scheduler doesn’t assign new tasks to the node, but
existing tasks remain running.
Drain means the scheduler doesn’t assign new tasks to the node. The
scheduler shuts down any existing ta...
This example implements a custom binding that toggles visibility (similar to the existing visible binding), but will utilize jQuery's fading API to animate the transition from visible to invisible.
Custom binding definition:
//Add a custom binding called "fadeVisible" by adding it as a p...
Set this attribute in your manifest's or element to enable or disable multi-window display:

Xcode 8 will automatically recognize any images you’ve got in an Asset Catalog and offer them up as a suggestion inside of a UIImage initializer.
So you could basically declare a new variable and then add an asset name that you have added to your asset catalog. For example let img = dog. img does n...
