To compute a signature:
final PrivateKey privateKey = keyPair.getPrivate();
final byte[] data = "FOO BAR".getBytes();
final Signature signer = Signature.getInstance("SHA1withRSA");
signer.initSign(privateKey);
signer.update(data);
final byte[] signature = signer.sign();...
'Note: I use this method to extract non-html data in extracted GET telnet results
'This example effectively grabs every other vehicle that have start and finish
'characters, which in this case is "/".
'Resulting in an array like this:
'extractedData(0) = "/Jeep"

It is common to use a background Thread for doing network operations or long running tasks, and then update the UI with the results when needed.
This poses a problem, as only the main thread can update the UI.
The solution is to use the runOnUiThread() method, as it allows you to initiate code exe...
The most important part of your RMD file is the YAML header. For writing an academic paper, I suggest to use PDF output, numbered sections and a table of content (toc).

A good and easy alternative to the flawed rand() procedures, is xorshift, a class of pseudo-random number generators discovered by George Marsaglia. The xorshift generator is among the fastest non-cryptographically-secure random number generators. More information and other example implementaions ar...
When a Component is resolved from the Windsor container it must have a definition of the scope it is in. By scope meaning if and how it is reused and when to release the object for the Garbage Collector to destroy. This is the LifeStlye of the Component.
The way to specify a LifeStyle is by registe...
By implementing your custom IScopeAccessor you can create different types of scopes. For the following example I have the two classes Foo and Bar in which Bar will be registered with a custom LifeStyle.
Each have an Id to assist with testing
public class Foo
{
public Guid FooId { get; } = G...
Since ls() finds objects by names, it's a handy way to find out if an object is present in the scene. ls() with a list of objects will only return the ones which are in the scene.
available_characters = cmds.ls('fred', 'barney', 'wilma', 'dino')
# available_characters will contain only the named...

Given a file like this:
$ cat file
hello/how/are/you
i am fine
You can use /pattern/ to match specific lines:
$ sed -n '/hello/p' file
hello/how/are/you
If the pattern contains slashes itself, you can use another delimiter using \cBREc:
$ sed -n '\#hello/how#p' file
hello/how/are/you
