Returns a string (varchar) of repeated spaces. Parameters: integer expression. Any integer expression, up to 8000. If negative, null is returned. if 0, an empty string is returned. (To return a string longer then 8000 spaces, use Replicate. SELECT SPACE(-1) -- Returns NULL SELECT SPACE(0) -...

Repeats a string value a specified number of times. Parameters: string expression. String expression can be a character string or binary data. integer expression. Any integer type, including bigint. If negative, null is returned. If 0, an empty string is returned. SELECT REPLICATE('a', -1) ...

Definition of the category The Haskell types along with functions between types form (almost†) a category. We have an identity morphism (function) (id :: a -> a) for every object (type) a; and composition of morphisms ((.) :: (b -> c) -> (a -> b) -> a -> c), which obey category la...

Categorical products In category theory, the product of two objects X, Y is another object Z with two projections: π₁ : Z → X and π₂ : Z → Y; such that any other two morphisms from another object decompose uniquely through those projections. In other words, if there exist f₁ : W → X and f₂ : W →...

This example is not tied to any concrete GUI toolkit, like reactive-banana-wx does, for instance. Instead it shows how to inject arbitary IO actions into FRP machinery. The Control.Event.Handler module provides an addHandler function which creates a pair of AddHandler a and a -> IO () values. Th...

In reactive-banana the Event type represents a stream of some events in time. An Event is similar to an analog impulse signal in the sense that it is not continuous in time. As a result, Event is an instance of the Functor typeclass only. You can't combine two Events together because they may fire a...

To represent continious signals, reactive-banana features Behavior a type. Unlike Event, a Behavior is an Applicative, which lets you combine n Behaviors using an n-ary pure function (using <$> and <*>). To obtain a Behavior a from the Event a there is accumE function: main = do (...

When applied to a property of a domain class, the database will create a NOT NULL column. using System.ComponentModel.DataAnnotations; public class Person { public int PersonID { get; set; } [Required] public string PersonName { get; set; } } The resulting column wi...

[MaxLength(int)] attribute can be applied to a string or array type property of a domain class. Entity Framework will set the size of a column to the specified value. using System.ComponentModel.DataAnnotations; public class Person { public int PersonID { get; set; } [MinLength(...

Swift Bitwise operators allow you to perform operations on the binary form of numbers. You can specify a binary literal by prefixing the number with 0b, so for example 0b110 is equivalent to the binary number 110 (the decimal number 6). Each 1 or 0 is a bit in the number. Bitwise NOT ~: var number...

Overflow refers to what happens when an operation would result in a number that is either larger or smaller than the designated amount of bits for that number may hold. Due to the way binary arithmetic works, after a number becomes too large for its bits, the number overflows down to the smallest p...
