First off, let's assume this is your initial model, inside an application called discography:
from django.db import models
class Album(models.Model):
name = models.CharField(max_length=255)
artist = models.CharField(max_length=255)
Now, you realize that you want to use a ForeignKey ...
You cannot alter the array's contents through the loop variable because it's a temporary each element is being assigned to.

Dim trace 'track iteration details
cars(0) = "Ford"
cars(1) = "Audi"

Your typical jQuery object will contain references to any number of DOM elements, and that's why jQuery objects are often referred to as collections. If you want to do any manipulating with specific elements (e.g. getting a data attribute, calculating specific positions) then you need to use .each()...

Here, a cursor is used to loop through all databases.
Futhermore, a cursor from dynamic sql is used to query each database returned by the first cursor.
This is to demonstrate the connection-scope of a cursor.

DECLARE @sql nvarchar(MAX)

The following code will attempt to execute loadFromHttp() up to 5 times (maxAttempts), with each attempt delayed by as many seconds. If maxAttempts is surpassed, the Observable gives up.
// assume loadFromHttp() returns a Promise, which might fail.

In case you need different settings for your various applications, there is (as of Flink 1.2) no easy way to do that.
If you use the one-yarn-cluster-per-job mode of flink (i.e. you launch your scripts with: flink run -m yarn-cluster ...), here is a workaround :
create a conf directory somewhe...
This is shortest, easiest and most commonly used method. Unfortunately, it has one major limitation - cannot be used on searches with more than 4000 results (rows).
// Assume that 'N/search' module is included as 'search'
var s = search.create({
type : search.Type.TRANSACTIO...
each and eachWithIndex are methods to iterate over collections.
each have it(default iterator) and eachWithIndex have it,index(default iterator, default index).
We can also change the default iterator/index. Please see below examples.
def list = [1,2,5,7]
list.each{
println it
}

HTML:
<ul>
<li>Mango</li>
<li>Book</li>
</ul>
Script:
$( "li" ).each(function( index ) {
console.log( index + ": " + $( this ).text() );
});
A message is thus logged for each item in the list:
0: Mango
1: Book
Many modern Image Processing algorithms use patches are their basic element to work on.
For instance one could denoise patches (See BM3D Algorithm).
Yet when building the image form the processed patches we have many results for the same pixel.
One way to deal with it is taking the average (Empir...
