The URLRequestMethod class contains constants for the various request types you can make. These constants are to be allocated to URLRequest's method property:
var request:URLRequest = new URLRequest('http://someservice.com');
request.method = URLRequestMethod.POST;
Note that only GET and POST...
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...
Flash will not load data from a domain other than the one your application is running on unless that domain has an XML crossdomain policy either in the root of the domain (e.g. http://somedomain.com/crossdomain.xml) or somewhere that you can target with Security.loadPolicyFile(). The crossdomain.xml...
Assuming we have an array myArray:
var value:* = myArray[int(Math.random() * myArray.length)];
Note we use int to cast the result of Math.random() to an int because values like 2.4539543 would not be a valid array index.
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.

To get any random color:
function randomColor():uint
{
return Math.random() * 0xFFFFFF;
}
If you need more control over the red, green and blue channels:
var r:uint = Math.random() * 0xFF;
var g:uint = Math.random() * 0xFF;
var b:uint = Math.random() * 0xFF;
var color:uint = r <&...
This is the built-in way to deal with "exceptions" without relying on third party libraries like Try::Tiny.
my $ret;
eval {
$ret = some_function_that_might_die();
1;
} or do {
my $eval_error = $@ || "Zombie error!";
handle_error($eval_error);
};
# use $ret

Current file
You can get the name of the current PHP file (with the absolute path) using the __FILE__ magic constant. This is most often used as a logging/debugging technique.
echo "We are in the file:" , __FILE__ , "\n";
Current directory
To get the absolute path to the di...
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...
std::sort, found in the standard library header algorithm, is a standard library algorithm for sorting a range of values, defined by a pair of iterators. std::sort takes as the last parameter a functor used to compare two values; this is how it determines the order. Note that std::sort is not stable...
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...
