When Flash makes a request for data from an external source, that operation is asynchronous. The most basic explanation of what this means is that the data loads "in the background" and triggers the event handler you allocate to Event.COMPLETE when it is received. This can happen at any po...
First define the circle radius and its center:
var radius:Number = 100;
var center:Point = new Point(35, 70);
Then generate a random angle in radians from the center:
var angle:Number = Math.random() * Math.PI * 2;
Then generate an effective radius of the returned point, so it'll be inside ...
If you need to roll for a true or false in an "x% chance" situation, use:
function roll(chance:Number):Boolean {
return Math.random() >= chance;
}
Used like:
var success:Boolean = roll(0.5); // True 50% of the time.
var again:Boolean = roll(0.25); // True 25% of the time.
...
Gets System.Type object for a type.
System.Type type = typeof(Point) //System.Drawing.Point
System.Type type = typeof(IDisposable) //System.IDisposable
System.Type type = typeof(Colors) //System.Drawing.Color
System.Type type = typeof(List<>) //System.Collections....
Value Type (where T : struct)
The built-in primitive data types, such as char, int, and float, as well as user-defined types declared with struct, or enum. Their default value is new T() :
default(int) // 0
default(DateTime) // 0001-01-01 12:00:00 AM
default(char) // '...
array_chunk() splits an array into chunks
Let's say we've following single dimensional array,
$input_array = array('a', 'b', 'c', 'd', 'e');
Now using array_chunk() on above PHP array,
$output_array = array_chunk($input_array, 2);
Above code will make chunks of 2 array elements and create a...
The first step in optimizing for speed is finding the slowest sections of code. The Timer VBA function returns the number of seconds elapsed since midnight with a precision of 1/256th of a second (3.90625 milliseconds) on Windows based PCs. The VBA functions Now and Time are only accurate to a secon...
A series is a one-dimension data structure. It's a bit like a supercharged array, or a dictionary.
import pandas as pd
s = pd.Series([10, 20, 30])
>>> s
0 10
1 20
2 30
dtype: int64
Every value in a series has an index. By default, the indices are integers, running fro...
Simple example of how to create a custom plugin and DSL for your gradle project.
This sample uses one of the three possible ways of creating plugins.
The three ways are:
inline
buildSrc
standalone plugins
This example shows creating a plugin from the buildSrc folder.
This sample will crea...
The Flex compiler (mxmlc) is one of the most important parts of the Flex SDK. You can edit AS3 code in any text editor you like. Create a main class file that extends from DisplayObject.
You can trigger builds at the command line as follows:
mxmlc -source-path="." -default-size [width in...
To make a Haskell program executable you must provide a file with a main function of type IO ()
main :: IO ()
main = putStrLn "Hello world!"
When Haskell is compiled it examines the IO data here and turns it into a executable. When we run this program it will print Hello world!.
If y...
Output some information about a known remote: origin
git remote show origin
Print just the remote's URL:
git config --get remote.origin.url
With 2.7+, it is also possible to do, which is arguably better than the above one that uses the config command.
git remote get-url origin
The static method Date.now returns the number of milliseconds that have elapsed since 1 January 1970 00:00:00 UTC. To get the number of milliseconds that have elapsed since that time using an instance of a Date object, use its getTime method.
// get milliseconds using static method now of Date

valet park
This command will register your current working directory as a path that Valet should search for sites. Now, any Laravel project you create within your "parked" directory will automatically be served using the http://folder-name.dev convention.
In a Service Provider register method we can bind an interface to an implementation:
public function register()
{
App::bind( UserRepositoryInterface::class, EloquentUserRepository::class );
}
From now on, everytime the app will need an instance of UserRepositoryInterface, Larave...
Solution 1:
$('#parent').prepend($('#child'));

Equality
For basic equality testing, the equal operator == is used. For more comprehensive checks, use the identical operator ===.
The identical operator works the same as the equal operator, requiring its operands have the same value, but also requires them to have the same data type.
For exampl...
