This trick helps you select an element using the ID as a value for an attribute selector to avoid the high specificity of the ID selector.
HTML:
<div id="element">...</div>
CSS
#element { ... } /* High specificity will override many selectors */
[id="element&quo...
A class can have non-static member functions, which operate on individual instances of the class.
class CL {
public:
void member_function() {}
};
These functions are called on an instance of the class, like so:
CL instance;
instance.member_function();
They can be defined either ins...
One can verify whether a method was called on a mock by using Mockito.verify().
Original mock = Mockito.mock(Original.class);
String param1 = "Expected param value";
int param2 = 100; // Expected param value
//Do something with mock
//Verify if mock was used properly
Mockito.veri...
Factory Method is one of creational design patterns. It is used to deal with the problem of creating objects without specifying exact result type. This document will teach you how to use Factory Method DP properly.
Let me explain the idea of it to you on a simple example. Imagine you're working in ...
var client = new MongoClient("mongodb://localhost:27017");
var database = client.GetDatabase("test");
var collection = database.GetCollection < Interactions > ("Interactions");
var newItem = new Interactions{
SiteName = "Example",
Pages = ...
var client = new MongoClient("mongodb://localhost:27017");
var database = client.GetDatabase("test");
var collection = database.GetCollection < Interactions > ("Interactions");
var result = IMongoCollectionExtensions
.AsQueryable(collection)

Static .Net library methods can be called from PowerShell by encapsulating the full class name in third bracket and then calling the method using ::
#calling Path.GetFileName()
C:\> [System.IO.Path]::GetFileName('C:\Windows\explorer.exe')
explorer.exe
Static methods can be called from the c...
To ensure that all possible items are documented, you can use the missing_docs link to receive warnings/errors from the compiler. To receive warnings library-wide, place this attribute in your lib.rs file:
#![warn(missing_docs)]
You can also receive errors for missing documentation with this lin...
Rust provides two types of documentation comments: inner documentation comments and outer documentation comments. Examples of each are provided below.
Inner Documentation Comments
mod foo {
//! Inner documentation comments go *inside* an item (e.g. a module or a
//! struct). They use th...
Code in documentation comments will automatically be executed by cargo test. These are known as "documentation tests", and help to ensure that your examples work and will not mislead users of your crate.
You can import relative from the crate root (as if there were a hidden extern crate ...
One big problem is that valuable named routes is not supported by Express out of the box. Solution is to install supported third-party package, for example express-reverse:
npm install express-reverse
Plug it in your project:
var app = require('express')();
require('express-reverse')(app);

The standard (17.6.4.2.1/1) generally forbids extending the std namespace:
The behavior of a C++ program is undefined if it adds declarations or definitions to namespace std or to a namespace within namespace std unless otherwise specified.
The same goes for posix (17.6.4.2.2/1):
The behavi...
Template method pattern is a behavioral design pattern that defines the program skeleton of an algorithm in an operation, defering some steps to subclasses.
Structure:
Key notes:
Template method uses Inheritance
The Template method implemented by the base class should not be overridden. In t...
Since Java lambdas are closures, they can "capture" the values of variables in the enclosing lexical scope. While not all lambdas capture anything -- simple lambdas like s -> s.length() capture nothing and are called stateless -- capturing lambdas require a temporary object to hold the...
