Serial.begin(speed) // Opens the serial port on the given baud rate Serial.begin(speed, config) Serial[1-3].begin(speed) // Arduino Mega only! When writing 1-3 it means you can choose between the numbers 1 to 3 when choosing the serial port. Serial[1-3].begin(speed, config) // Arduino Mega onl...

The std::sort function family is found in the algorithm library.

Parallelization on remote machines require libraries to be downloaded on each machine. Prefer package::function() calls. Several packages have parallelization natively built-in, including caret, pls and plyr. Microsoft R Open (Revolution R) also uses multi-threaded BLAS/LAPACK libraries which int...

This extension filters data by either validating or sanitizing it. This is especially useful when the data source contains unknown (or foreign) data, like user supplied input. For example, this data may come from an HTML form. mixed filter_var ( mixed $variable [, int $filter = FILTER_DEFAULT ...

JDBC, or Java DataBase Connectivity, is the Java specification for connecting to (relational) databases. JDBC provides a common API in the form of a number of interfaces and exceptions, and expectations (or requirements) of drivers. The JDBC specification consists of two parts: A specification...

Given an R object, we may require separate analysis for one or more parts of the data contained in it. The process of obtaining these parts of the data from a given object is called subsetting. Missing values: Missing values (NAs) used in subsetting with [ return NA since a NA index picks ...

define ( string $name , mixed $value [, bool $case_insensitive = false ] ) const CONSTANT_NAME = VALUE; Constants are used to store the values that are not supposed to be changed later. They also are often used to store the configuration parameters especially those which define the environ...

This topic provides examples for unit testing the various constructs in AngularJS. Unit tests are often written using using Jasmine, a popular behavior driven testing framework. When unit testing angular constructs, you will need to include ngMock as a dependency when running the unit tests.

There are some cases where your application cannot manipulate the contents of assets loaded from an external resource (e.g. transform images). I can't remember for certain what they are, but I am fairly sure it's related to cross domain content loading.
