Redis provides two functions for removing keys from the database: del and unlink.
The del function removes one or more keys from the database. The del command causes Redis to immediately reclaim the memory for the deleted key on the current thread of execution. The execution time for del is propo...
To create a new project ng new [project-name] which initializes git.Install packages for tooling via npm. It creates the project successfully.
cd [project-name] and execute either npm start or ng serve
It'll run the server in the given default port.

The Sales Orders screen (SO.30.10.00) is a perfect example of a data entry form with a composite primary key. The primary key on the Sales Orders screen is composed by the Order Type and the Order Number:
The recommended 2-step strategy to export data from the Sales Orders screen or any other dat...
Given the following custom Boolean type we want to wrap:
typedef char MYBOOL;
#define TRUE 1
#define FALSE 0
A simple approach might be to write the following typemaps in our SWIG interface:
%typemap(in) MYBOOL %{
// $input is what we got passed from Python for this function argument
$1...
Go to terminal,
cd projectFolder
git remote -v (it will show previous git url)
git remote set-url origin https://[email protected]/username/newName.git
git remote -v (double check, it will show new git url)
git push (do whatever you want.)
Currying is the process of transforming a function that takes multiple arguments into a sequence of functions that each has only a single parameter. Currying is related to, but not the same as, partial application.
Let's consider the following function in JavaScript:
var add = (x, y) => x + y
...
bindings: {
mandatory: '='
optional: '=?',
foo: '=?bar'
}
Optional attributes should be marked with question mark: =? or =?bar. It is protection for ($compile:nonassign) exception.
We injecting the module in the application
var Registration=angular.module("myApp",["ngRoute"]);
now we use $routeProvider from "ngRoute"
Registration.config(function($routeProvider) {
});
finally we integrating the route, we define "/ad...
In traditional object-oriented languages, x = x + 1 is a simple and legal expression. But in Functional Programming, it's illegal.
Variables don't exist in Functional Programming. Stored values are still called variables only because of history. In fact, they are constants. Once x takes a value, it...
A single line comment starts with two hyphens (--) and extends up to the end of the line. Example :
-- This process models the state register
process(clock, aresetn)
begin
if aresetn = '0' then -- Active low, asynchronous reset
state <= IDLE;
elsif rising_edge(clock) then --...
Starting with VHDL 2008, a comment can also extend on several lines. Multi-lines comments start with /* and end with */. Example :
/* This process models the state register.
It has an active low, asynchronous reset
and is synchronized on the rising edge
of the clock. */
process(clock, ...
Redis provides three commands to count the items within a sorted set: ZCARD, ZCOUNT, ZLEXCOUNT.
The ZCARD command is the basic test for the cardinality of a set. (It is analogous to the SCARD command for sets.) . ZCARD returns the count of the members of a set.
Executing the following code to add...
Pointers are variables that store the address of another variable.As language feature they are available in several programming languages like, but not limited to :
Go
C/C++
Ada
Pascal
C# (available under certain constraints)
COBOL
FORTRAN
To get started with C/C++ pointers , follow thes...
If you do not only wish to display static objects, but have your UI respond to changes to correlating objects, you need to understand the basics of the INotifyPropertyChanged interface.
Assuming we have our MainWindowdefined as

This example will go over the basic structure of a Cucumber feature file in Gherkin. Feature files use several keywords in the basic syntax.
Lets look at the basic keywords:
Feature: this keyword signifies that what follows is a basic description or name of the feature being tested or documented...
When writing Gherkin, there may be times in which you want to parameterize your steps for reusability by the engineer who is implementing the test plans. Steps receive parameters through regular expression capturing groups. (Engineering Note: If you do not have matching parameters for each capturing...
In some cases you may want to rerun the same scenario over and over, substituting out the arguments. In this case, Gherkin provides several new keywords to accommodate this situation, Scenario Outline: and Example:. The Scenario Outline keyword tells Cucumber that the scenario is going to run multip...
