The advantages of using Session State are 1)Better security 2)Reduced bandwidth The disadvantages of using Session state are 1)More resource consumption of server. 2)Extra code/care if a Web farm is used(we will discuss this shortly) **Session State Modes** ...

<svg width="400px" height="200px"> <text x="1em, 2em, 3em, 4em, 5em" y="3em, 4em, 5em"> Individually Spaced Text </text> </svg> The Text element supports individual placement of letters by accepting an array of values for...

Interfaces and implementations (types that implement an interface) are "detached". So it is a rightful question how to check at compile-time if a type implements an interface. One way to ask the compiler to check that the type T implements the interface I is by attempting an assignment us...

First, download a copy of SFML from the official page. Save it anywhere in your computer where it can be easily accessed. Open Codeblocks. Go to Project->Build Options->LinkerSettings tab. Click on the Add button and go to the bin folder of SFML and select all the files present there...

A simple worker pool implementation: package main import ( "fmt" "sync" ) type job struct { // some fields for your job type } type result struct { // some fields for your result type } func worker(jobs <-chan job, results chan<- result) ...

Returns the starting position of the first occurrence of a the specified pattern in the specified expression. Parameters: pattern. A character expression the contains the sequence to be found. Limited to A maximum length of 8000 chars. Wildcards (%, _) can be used in the pattern. If the patter...

runOutsideAngular can be used to run code outside Angular 2 so that it does not trigger change detection unnecessarily. This can be used to for example run multiple HTTP request to get all the data before rendering it. To execute code again inside Angular 2, run method of NgZone can be used. my.com...

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 →...

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 (...
