Implementation of the Caesar cipher. This implementation performs the shift operation only on upper and lower case alphabets and retains the other characters (such as space as-is). The Caesar cipher is not secure as per current standards. Below example is for illustrative purposes only ! Refer...

The HTML5 file API allows you to restrict which kind of files are accepted by simply setting the accept attribute on a file input, e.g.: <input type="file" accept="image/jpeg"> Specifying multiple MIME types separated by a comma (e.g. image/jpeg,image/png) or using wild...

The following code example implements the Caesar cipher and shows the properties of the cipher. It handles both uppercase and lowercase alpha-numerical characters, leaving all other characters as they were. The following properties of the Caesar cipher are shown: weak keys; low key space; the...

// Initalize a new queue of integers var queue = new Queue<int>(); // Add some data queue.Enqueue(6); queue.Enqueue(4); queue.Enqueue(9); // Elements in a queue are stored in "first in, first out" order. // The queue from first to last is: 6, 4, 9 // View the next ele...

To create an explosion, the following method signatures may be used: boolean createExplosion(double x, double y, double z, float power); boolean createExplosion(double x, double y, double z, float power, boolean setFire); boolean createExplosion(double x, double y, double z, float power, ...

The following methods can be used to drop an Item somewhere in the world: Item dropItem(Location loc, ItemStack is); Item dropItemNaturally(Location loc, ItemStack is); dropItem means dropping an Item exactly at the location, returning an Item object. dropItemNaturally means dropping the Item ...

The following methods can be used to generate a tree naturally (as if it was grown from a sapling) into the world. boolean generateTree(Location loc, TreeType type); boolean generateTree(Location loc, TreeType type, BlockChangeDelegate delegate); Location is where you want the tree to spawn ...

When working with components, such as vertices or uv points, Maya defaults to returning a colon-separated range rather than individual items: print cmds.ls('pCube1.vtx[*]') # get all the vertices in the cube # [u'pCube1.vtx[0:7]'] You can use ls with the flatten option to force Maya to expan...

Where we came from Sometimes we can't provide all of the required metadata needed for the XmlSerializer framework in attribute. Suppose we have a base class of serialized objects, and some of the derived classes are unknown to the base class. We can't place an attribute for all of the classes which...

Unary operators are operators with only one operand. Unary operators are more efficient than standard JavaScript function calls. Additionally, unary operators can not be overridden and therefore their functionality is guaranteed. The following unary operators are available: OperatorOperationExampl...

In Production its good practice to secure your data and only allow operations on it to be undertaken via Stored Procedures. This means your application can't directly run CRUD operations on your data and potentially cause problems. Assigning permissions is a time-consuming, fiddly and generally oner...

This is just a small hack for those who use self-defined functions often. Type "fun" RStudio IDE and hit TAB. The result will be a skeleton of a new function. name <- function(variables) { } One can easily define their own snippet template, i.e. like the one below ...
