Code visualization presents a visual representation of the state of the code to support code comprehension activities. In addition to representing code elements (for example, methods, classes and packages) and relationships between them, previous studies of code visualization also represent metrics to indicate code smell. However, the metric value only shows vague symptoms in describing the code smell behind it. This study tries to visualize the code smell directly using detection strategies, which are formulation of one or more than one metric and its threshold value for each type of code smell. `Smelly' elements are immediately shown in code visualization according to the predetermined detection strategies. 3D mushroom farm metaphor is a new metaphor proposed in this study for code visualization. Through code visualization in a familiar natural 3D environment, code properties are displayed in an attractive manner. The presented code properties are chosen by considering object-oriented paradigm key ideas. During this time, there has never been a fundamental reason as to why a specific property was chosen to be included in a code visualization metaphor. Therefore, this study questioned code properties visualized to participants of the evaluation: is the early comprehension of the code sufficient enough or should it be added/reduced. The evaluation results showed that the code smell that was immediately shown in the visualization could be captured by the user correctly. All evaluated participants managed to identify all the smelly elements. Broadly speaking, participants understood the purpose of visualization and agreed that code visualization with the 3D mushroom farm metaphor is intuitive and easy to use. All participants stated that they needed all code properties displayed in code visualization with the 3D mushroom farm metaphor, although there were participants who proposed several properties to be added to the visualization.

There is a significant number of unpublished research by university lecturers and students about Gorontalo's local medicinal plants that have contributed to the insufficiency of information to the society regarding the benefits of local medicinal plants. Moreover, the public lacks digital backup and documentation of the medicinal plants referred. This research aims to create a web database of Gorontalo's local medicinal plant, by comprising waterfall method of software engineering approach. The waterfall method involves four steps. The first step is system requirement analysis through preliminary study and observation based on field study and library research. The second is system design, by context diagram and system architecture designs, i.e., use case diagram, class diagram, activity diagram, and database design. The third is coding using PHP programming language by OOP (object oriented programming) concept and MVC (model view controller) architecture. The last step is system test using the black-box testing method. The result shows that the web application designed is able to operate properly.

The complexity and difficulty for designing and developing automation programs based on the IEC 61131-3 [1] is continuously increasing. With the VDI/VDE/NAMUR 2658 [2] a new level of complexity will be reached - control modules with more complex interfaces, services as functional capsulation in process operations and interdependencies to other unknown up-or downstream modules. In these applications, the proven procedural approach reaches its limits. The object-oriented paradigm could be the solution. However the object-oriented extension of [1] is not supported in many available plc development tools. This results in a low acceptance and low experience in object-oriented thinking by plc developers. This paper will be focused on an object-oriented motivated transformation of design principles and patterns into Structured Text. The results are demonstrated in form of a best practice implementation for programs compliant to [2]. The presented approach does not use any kind of supportive or generating tools, it's based completely on the possibilities of IEC 61131-3.
We present GOOL, a Generic object-oriented Language. It demonstrates that a language, with the right abstractions, can capture the essence of object-oriented programs. We show how GOOL programs can be used to generate...

Exploit the features of TypeScript to easily create your very own web applications
About This Book
• Develop modular, scalable, maintainable, and adaptable web applications by taking advantage of TypeScript
• Walk through the fundamentals of TypeScript with the help of practical examples
• Enhance your web development skills using TypeScript 2.x
Who This Book Is For
If you are a developer aiming to learn TypeScript to build attractive web applications, this book is for you. No prior knowledge of TypeScript is required. However, a basic understanding of JavaScript would be an added advantage.
What You Will Learn
• Understand TypeScript in depth, including its runtime and advanced type system features
• Master the core principles of the object-orientedprogramming and functional programming paradigms with TypeScript
• Save time using automation tools such as Gulp, Webpack, ts-node, and npm scripts
• Develop robust, modular, scalable, maintainable, and adaptable applications with testing frameworks such as Mocha, Chai, and ***
• Put your TypeScript skills to practice by developing full-stack web applications with ***, React and Angular
• Use the APIs of the TypeScript compiler to build custom code analysis tool
In Detail
TypeScript is an open source and cross-platform statically typed superset of JavaScript that compiles to plain JavaScript and runs in any browser or host.
This book is a step-by-step guide that will take you through the use and benefits of TypeScript with the help of practical examples. You will start off by understanding the basics as well as the new features of TypeScript 2.x. Then, you will learn how to work with functions and asynchronous programming APIs. You will continue by learning how to resolve runtime issues and how to implement TypeScript applications using the object-orientedprogramming (OOP) and functional programming (FP) paradigms. Later, you will automate your development workflow with the help of tools such as Webpac

With an interesting mix of theory and practicals, explore Python and its features, and progress from beginner to being skilled in this popular scripting language
Key Features
• A comprehensive introduction to the world of Python programming
• Paves an easy-to-follow path for you to navigate through concepts
• Filled with over 90 practical exercises and activities to reinforce your learning
Book Description
After a brief history of Python and key differences between Python 2 and Python 3, you'll understand how Python has been used in applications such as YouTube and Google App Engine. As you work with the language, you'll learn about control statements, delve into controlling program flow and gradually work on more structured programs via functions.
As you settle into the Python ecosystem, you'll learn about data structures and study ways to correctly store and represent information. By working through specific examples, you'll learn how Python implements object-orientedprogramming (OOP) concepts of abstraction, encapsulation of data, inheritance, and polymorphism. You'll be given an overview of how imports, modules, and packages work in Python, how you can handle errors to prevent apps from crashing, as well as file manipulation.
By the end of this book, you'll have built up an impressive portfolio of projects and armed yourself with the skills you need to tackle Python projects in the real world.
What you will learn
• Use control statements
• Manipulate primitive and non-primitive data structures
• Use loops to iterate over objects or data for accurate results
• Write encapsulated and succinct Python functions
• Build Python classes using object-orientedprogramming
• Manipulate files on the file system (open, read, write, and delete)
Who this book is for
Python Fundamentals is great for anyone who wants to start using Python to build anything from simple command-line programs to web applications. Prior knowledge of Python isn't required.
