The objects created within a Tiled Map (.tmx), can be simply loaded as bodies into a Box2D world using the Libgdx MapObject class as following:
public void buildBuildingsBodies(TiledMap tiledMap, World world, String layer){
MapObjects objects = tiledMap.getLayers().get(layer).getObjects();

In Internet Explorer 10+ and Edge, Microsoft provides the -ms-high-contrast media selector to expose the "High Contrast" setting from the browser, which allows the programmer to adjust their site's styles accordingly.
The -ms-high-contrast selector has 3 states: active, black-on-white, ...
In this example you will learn how to generate RSA-OAEP key pair and how to convert private key from this key pair to base64 so you can use it with OpenSSL etc. Please note that this process can also be used for public key you just have to use prefix and suffix below:

In the light of the latest httpoxy vulnerabilities, there is another variable, that is widely misused.
HTTP_X_FORWARDED_FOR is often used to detect the client IP address, but without any additional checks, this can lead to security issues, especially when this IP is later used for authentication or...
Suppose you want to prevent unauthorized users to access the page then you have to put barrier to them by authorizing access. We can do this by using spring-security which provides basic authentication by securing all HTTP end points. For that you need to add spring-security dependency to your proje...
C99
Since C99, C has variable length arrays, VLA, that model arrays with bounds that are only known at initialization time. While you have to be careful not to allocate too large VLA (they might smash your stack), using pointers to VLA and using them in sizeof expressions is fine.
double sumAll(si...
There is a limit to the depth of possible recursion, which depends on the Python implementation. When the limit is reached, a RuntimeError exception is raised:
RuntimeError: Maximum Recursion Depth Exceeded
Here's a sample of a program that would cause this error:
def cursing(depth):
try:
...
When the only thing returned from a function is a recursive call, it is refered to as tail recursion.
Here's an example countdown written using tail recursion:
def countdown(n):
if n == 0:
print "Blastoff!"
else:
print n
countdown(n-1)
Any computat...
We can declare a series of expressions in the REPL like this:
Prelude> let x = 5
Prelude> let y = 2 * 5 + x
Prelude> let result = y * 10
Prelude> x
5
Prelude> y
15
Prelude> result
150
To declare the same values in a file we write the
following:
-- demo.hs
module De...
A common mistake a lot of people starting out with FileSystemWatcher does is not taking into account That the FileWatcher event is raised as soon as the file is created.
However, it may take some time for the file to be finished .
Example:
Take a file size of 1 GB for example . The file apr ask c...
Dependencies can be added for specific configuration like test/androidTest
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
testCompile 'junit:junit:3.8.1'
Alternatively create your own configuration
configurations {
myconfig
}
And then download dependency fo...
Placeholders can be used in strings to automatically substitute the values in the final string.
container = "cup"
liquid = "coffee"
string = "Filling the #{container} with #{liquid}..."
The above String - when printed - will say: Filling the cup with coffee...

The disabled binding adds a disabled attribute to a html element causing it to no longer be editable or clickable.
This is useful mainly for <input>, <select>, <textarea>, <a> and <button> elements
<input data-bind="disabled: disableInput"/>

Many bugs in knockout data binds are caused by undefined properties in a viewmodel. Knockout has two handy methods to retrieve the binding context of an HTML element:
// Returns the binding context to which an HTMLElement is bound
ko.contextFor(element);
// Returns the viewmodel to which ...
CREATE TABLE all_datetime_types(
c_date date,

Minimum and maximum data values:
insert into all_datetime_types values ('0001-01-01','0001-01-01 00:00:00.000000001');
insert into all_datetime_types values ('9999-12-31','9999-12-31 23:59:59.999999999');
