Home - Open.Source - everything ! FREE SOFTWARE !!! for Windows, Linux & Mac Object Oriented Programming Tutorial - Objects Objects are the central idea behind OOP. The idea is quite simple. An object is a bundle of variables and related methods. method is similar to a procedure; we'll come back to these later. The basic idea behind an object is that of simulation . methods associated with that object, in other words, functions that modify the objects attributes. A few examples should help explain this concept. Drink! Say we want to write a program about a pint of beer. TYPE BeerType = RECORD BeerName: STRING; VolumeInPints: REAL; Colour: ColourType; Proof: REAL; PintsNeededToGetYouDrunk: CARDINAL; ... Now lets say we want to initialise a pint of beer, and take a sip from it. VAR MyPint: BeerType; BEGIN ... (* Initialise (i.e. buy) a pint: *) MyPint.BeerName := "Harp"; MyPint.VolumeInPints := 1.00; ... ... (* Take a sip *) MyPint.VolumeInPints := MyPint.VolumeInPints - 0.1; ... We have constructed this entire model based entirely on data types A method is an operation which can modify an objects behaviour. .
Indoor Navigation with SVG SVG, positioning technologies, mobility, guiding system Christian SchmittResearcherFraunhofer FIT Schloss Birlinghoven Sankt-Augustin Germany christian.schmitt@fit.fraunhofer.de Oliver KaufmannFraunhofer FITSchloss Birlinghoven Sankt-Augustin Germany oliver.kaufmann@fit.fraunhofer.de This paper describes a mobile guide providing office building visitors with indoor navigation aid. 1. 1. FIT has a long history in developing mobile guides for museums, fairs, symposiums. Our mobile guide was developed with the aim to be used for demo purposes by visitors to our institute, for demonstrating our expertise in mobile computing, positioning technologies and human-computer interface. Present information about our research department (employees, projects)Let the user experience indoor navigation on our floor Presenting information can be easily achieved by integrating functionalities from the Pocket Internet Explorer in the application and having the content available as HTML pages. 2. 3. 4.
Learn HTML 5 in 3 days – Day 1 Introduction HTML 5 is one of the hot topic recent days. So I thought why don’t write a complete learning tutorial about same. It’s going to be a 2 days series article. Note: As a Microsoft guy whenever there is a need for server side technology I will be using C# and Asp.Net. What we won’t cover here? If you don’t know anything about HTML then this article is not for you. You can learn about basic HTML here. Agenda Introduction to HTML 5 Let’s first understand couple of basic and intriguing features about HTML unaware to most of the developers. What is difference between SGML, HTML and XML? What is difference between SGML, HTML and XML? SGML stands for Standard Globalized Markup language is the one used for defining standard markup languages. What is Doc type? When you try to create a HTML page using tools like Dreamweaver or Visual studio you will find following line at the top of the document always. Have you ever wondered what it is? How HTML 5 is different from previous versions? Number Range
What Is an Interface? (The Java™ Tutorials > Learning the Java Language > Object-Oriented Programming Concepts) As you've already learned, objects define their interaction with the outside world through the methods that they expose. Methods form the object's interface with the outside world; the buttons on the front of your television set, for example, are the interface between you and the electrical wiring on the other side of its plastic casing. You press the "power" button to turn the television on and off. In its most common form, an interface is a group of related methods with empty bodies. interface Bicycle { // wheel revolutions per minute void changeCadence(int newValue); void changeGear(int newValue); void speedUp(int increment); void applyBrakes(int decrement); } To implement this interface, the name of your class would change (to a particular brand of bicycle, for example, such as ACMEBicycle), and you'd use the implements keyword in the class declaration: Implementing an interface allows a class to become more formal about the behavior it promises to provide.
Indoor Autonomous Positioning SCP technology makes it possible to provide reliable, consistent, and accurate indoor positioning without the support of network infrastructure and services. By exploiting freely available signals including GPS, cellular, digital television, and wireless LAN (e.g. WiFi), SCP based Doppler Aided Inertial Navigation (DAIN) determines location through a sensor fusion approach. Combining inertial, magnetic, and gravity data with the SCP RF observables, DAIN provides continuous position, velocity, and direction information. A fundamental breakthrough in indoor positioning, SCP DAIN is ideal for emerging location enabled applications hosted on smart phone devices. DAIN is an ideal enabler for both consumer and commercial applications.
Introduction — Problem Solving with Algorithms and Data Structures We stated earlier that Python is an object-oriented programming language. So far, we have used a number of built-in classes to show examples of data and control structures. One of the most powerful features in an object-oriented programming language is the ability to allow a programmer (problem solver) to create new classes that model data that is needed to solve the problem. Remember that we use abstract data types to provide the logical description of what a data object looks like (its state) and what it can do (its methods). A Fraction Class A very common example to show the details of implementing a user-defined class is to construct a class to implement the abstract data type Fraction. A fraction such as consists of two parts. The operations for the Fraction type will allow a Fraction data object to behave like any other numeric value. In Python, we define a new class by providing a name and a set of method definitions that are syntactically similar to function definitions.

Craps is a game with two states and a number of state-change rules. The chapters of this part presents the details on the game, an overview of the solution, and a series of eleven exercises to build a complete simulation of the game, with a variety of betting strategies. There are several examples of rework in this part, some of them quite extensive.
How to build your own Linux distro Since Manchester University's Owen Le Blanc released MCC Interim Linux (generally agreed to have been the first Linux distribution), way back in 1992, there have been hundreds of ways to get the world's favourite free software operating system on to a computer. The diversity of alternatives reflects the diversity in the development community, with distros split along technical, functional, linguistic and even ideological lines. There have been large distros, tiny ones, bleeding edge and rock-solid stable distros. Easy for the newbie to install, or downright impenetrable to the uninitiated. Created exclusively with free software as a badge of pride, or so proprietary in attitude that not even the toolchain was fully GNU (hello Red Flag Server 4.1, built with the Intel compiler in 2004). So with all the variety that's already out there, why would anyone want to create their own distro? What this amounts to is that it doesn't take much to warrant a new distro. Which base? The simple choices
SYWorks Programming: WAIDPS [Wireless Auditing, Intrusion Detection & Prevention System] Tutorial / Explanations - Part 4 Network Cracking (Auditing) Module WAIDPS also include with the Network auditing Module which allow user to crack a WEP encrypted access point (AP), capturing of WPA/WPA2 Handshake for cracking of WPA Passphase and also bruteforcing the PIN of a Wi-Fi Protected Setup (WPS) enabled router which thereafter revealing the WPA passphase. Apart from cracking of encrypted acess point, WAIDPS also include a “Live Monitoring” of Access Point which will show the detail of wireless clients associated to the specific Access Point. WARNING : The Network Cracking Module is strictly for auditing your own network or mutual consent of auditing someone network. Network Auditing Main Menu In order to get into the ‘Network Auditing’ selection menu, user can press [Enter] on the main menu followed by [A] to get into the auditing module. Note : Please allow the WiFi Harvester to harvest for access points and clients detail in the main screen before selecting the “Auditing Network” module.
