Bash Script to check internet connectivity

Today I decided to search for Linux website/blog LinuxScrew.

Here is example from website of very simple bash script to check internet connection:

#!/bin/bash

WGET="/usr/bin/wget";

$WGET -q --tries=10 --timeout=5 http://www.google.com -O /tmp/index.google &> /dev/null
if [ ! -s /tmp/index.google ];then
    echo "no"
else
    echo "yes"
fi

Singleton Pattern

Singleton Pattern is designed to restrict instantiation of a class to one object. The pattern can be used for global variables or database connection.

class Preferences {
    private $props = array();
    private static $instance;

    // cannot be instantiated
    private function __construct(); 
    
    public static function getInstance() {
        if ( empty( self::$instance )) {
            self::$instance = new Preferences();
        }
        return self::$instance;
    }
    
    public function setProperty( $key, $val ) {
        $this->props[$key] = $val;
    }  
  
    public function getProperty( $key ) {
        return $this->props[$key];
    }
}

UML - Unified Modeling Language

UML stands for Unified Modeling Language. Abstract classes are represented either by italicizing the class name or by adding {abstract} to the class name. Interfaces are defined in the same was as classes, except they must include a stereotype (<< interface >>). Visibility Symbols:
+ (Public, Available to all code)
- (Private, Available to the current class only)
# (Protected, Available to the current class and its subclasses only)

The UML describes the inheritance relationship as generalization. This relationship is signified by a line leading from the subclass to its parent. The line is tipped with an empty closed arrow.

The UML describes the relationship between an interface and the classes that implement it as realization(- - - |>)

An association occurs when a class property is declared to hold a reference to an instance (or instances) of another class).

Sequence Diagram is object based rather than class based. It is used to model a process in a system step by step.

Encapsulation

Encapsulation simply means the hiding of data and functionality from a client. On the simplest level, we encapsulate data by declaring properties private or protected. By hiding a property from client ode, we enforce an interface and prevent the accidental corruption of an object's data.

Polymorphism

Polymorphism, or class switching, is a common feature of object-oriented systems. Polymorphism is the maintenance implementations behind a common interface. Polymorphism illustrates another kind of encapsulation. By placing different implementations behind a common interface, we hide these underlying strategies from the client. This means that any changes that are made behind this interface are transparent to the wider system.

Dual-Core

Dual-core (DP) refers to a CPU that includes two complete execution cores per physical processor. It has combined two processors(cache and cache controllers) onto single integration circuit (silicon chip). DP processors are well-suited for multitasking environments because there are two complete execution cores instead of one, each with an independent interface to the front side bus. Since each core has its own cache, the operating system has sufficient resources to handle most compute intensive tasks in parallel.

Multi-core is similar to dual-core in that it is an expansion to the dual-core technology which allows for more than two separate processor.
