Some programs need so store arguments for future calling of some function.
This example shows how to call any function with arguments stored in std::tuple
#include <iostream>
#include <functional>

Using an Asynchronous Controller in ASP.NET MVC. The AsyncController class enables you to write asynchronous action methods. You can use asynchronous action methods for long-running, non-CPU bound requests. This avoids blocking the Web server from performing work while the request is being processed...
YouTube is an online video streaming service, unique in the fact that users can upload their own videos for the purposes of sharing whatever they recorded. This can range massively, from someone cooking breakfast, to playing a live concert. Now owned by Google Inc., this site has always been free to...
Typescript supports costant enumerables, declared through const enum.
This is usually just syntax sugar as the costant enums are inlined in compiled JavaScript.
For instance the following code
const enum Tristate {
True,
False,
Unknown
}
var something = Tristate.True;
compil...
The ConstainsKey method is the way to know if a key already exists in the Dictionary.
This come in handy for data reduction. In the sample below, each time we encountner a new word, we add it as a key in the dictionary, else we increment the counter for this specific word.
Dim dic As IDictionary(...
Pancake Sort is a the colloquial term for the mathematical problem of sorting a disordered stack of pancakes in order of size when a spatula can be inserted at any point in the stack and used to flip all pancakes above it. A pancake number is the minimum number of flips required for a given number o...

The Caesar cipher is a classic encryption method. It works by shifting the characters by a certain amount. For example, if we choose a shift of 3, A will become D and E will become H.
The following text has been encrypted using a 23 shift.

The ASCII way
This shifts the characters but doesn't care if the new character is not a letter. This is good if you want to use punctuation or special characters, but it won't necessarily give you letters only as an output. For example, "z" 3-shifts to "}".
def ceasar(text, shi...
ROT13 is a special case of Caesar cipher, with a 13 shift. Only letters are changed, and white-space and special characters are left as they are.
What is interesting is that ROT13 is a reciprocal cipher : applying ROT13 twice will give you the initial input. Indeed, 2 * 13 = 26, the number of lette...
To connect to a mongo database from node application we require mongoose.
Installing Mongoose
Go to the toot of your application and install mongoose by

With Mongoose, everything is derived from a Schema. Lets create a schema.
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var AutoSchema = new Schema({
name : String,
countOf: Number,
});
// defining the document structure
// by default the collection...
For inserting a new document in the collection, we create a object of the schema.
var Auto = require('models/auto')
var autoObj = new Auto({
name: "NewName",
countOf: 10
});
We save it like the following
autoObj.save(function(err, insertedAuto) {
if (err) return cons...
To call a list of goals as if it were a conjunction of goals, combine the higher-order predicates call/1 and maplist/2:
?- Gs = [X = a, Y = b], maplist(call, Gs).
Gs = [a=a, b=b],
X = a,
Y = b.
