First define the service (in this case it uses the factory pattern):
.factory('dataService', function() {
var dataObject = {};
var service = {
// define the getter method
get data() {
return dataObject;
},
// define the setter method

updateState by key can be used to create a stateful DStream based on upcoming data. It requires a function:
object UpdateStateFunctions {
def updateState(current: Seq[Double], previous: Option[StatCounter]) = {
previous.map(s => s.merge(current)).orElse(Some(StatCounter(current)))
}
...
mapWithState, similarly to updateState, can be used to create a stateful DStream based on upcoming data. It requires StateSpec:
import org.apache.spark.streaming._
object StatefulStats {
val state = StateSpec.function(
(key: String, current: Option[Double], state: State[StatCounter]) =&g...

The right-hand side of the assignment in a for loop can be any row vector. The left-hand side of the assignment can be any valid variable name. The for loop assigns a different element of this vector to the variable each run.
other_row_vector = [4, 3, 5, 1, 2];
for any_name = other_row_vector
...
If the right-hand side of the assignment is a matrix, then in each iteration the variable is assigned subsequent columns of this matrix.
some_matrix = [1, 2, 3; 4, 5, 6]; % 2 by 3 matrix
for some_column = some_matrix
display(some_column)
end
(The row vector version is a normal case of thi...
yii migrate/create <name>
The required name argument gives a brief description about the new migration. For example, if the migration is about creating a new table named news, you may use the name create_news_table and run the following command
yii migrate/create create_news_table
An abstract class is a class that cannot be instantiated. Abstract classes can define abstract methods, which are methods without any body, only a definition:
abstract class MyAbstractClass {
abstract public function doSomething($a, $b);
}
Abstract classes should be extended by a child cla...

Set memory limit and disable swap limit
docker run -it -m 300M --memory-swap -1 ubuntu:14.04 /bin/bash
Set both memory and swap limit. In this case, container can use 300M memory and 700M swap.
docker run -it -m 300M --memory-swap 1G ubuntu:14.04 /bin/bash
WCF tracing is built on top of System.Diagnostics. To use tracing, you should define trace sources in the configuration file or in code.
Tracing is not enabled by default. To activate tracing, you must create a trace listener and set a trace level other than "Off" for the selected trace s...
