In this article by Edwood Ng and Vineeth Mohan , authors of the book Lucene 4 Cookbook , we will cover the following recipes: Performing advanced filtering Creating a custom filter Searching with QueryParser TermQuery and TermRangeQuery BooleanQuery PrefixQuery and WildcardQuery PhraseQuery and MultiPhraseQuery FuzzyQuery
In this article by Donato Teutonico , author of the book ggplot2 Essentials , we are going to explore different plotting environments in R and subsequently learn about the package, ggplot2 . R provides a complete series of options available for realizing graphics, which make this software quite advanced concerning data visualization. The core of the graphics visualization in R is within the package grDevices , which provides the basic structure of data plotting, as for instance the colors and fonts used in the plots. Such graphic engine was then used as starting point in the development of more advanced and sophisticated packages for data visualization; the most commonly used being graphics and grid .
In this article by Pravin Ingawale , author of the book Oracle E-Business Suite R12.x HRMS – A Functionality Guide , will learn about entering a person's information in Oracle HRMS. We will understand the hiring process in Oracle. This, actually, is part of the Oracle I-recruitment module in Oracle apps. Then we will see how to create an employee in Core HR. Then, we will learn the concept of person types and defining person types. We will also learn about entering information for an employee, including additional information. Let's see how to create an employee in core HR.
In this article by Alan Thorn , author of the book, Unity Animation Essentials , you learn the fundamentals of animation. The importance of animation cannot be understated. Without animation, everything in-game would be statuesque, lifeless and perhaps boring. This holds true for nearly everything in games: doors must open, characters must move, foliage should sway with the wind, sparkles and particles should explode and shine, and so on. Consequently, learning animation and how to animate properly will unquestionably empower you as a developer, no matter what your career plans are. As a subject, animation creeps unavoidably into most game fields, and it's a critical concern for all members of a team—obviously for artists and animators, but also for programmers, sound designers, and level designers. The aim is to quickly and effectively introduce the fundamental concepts and practices surrounding animation in real-time games, specifically animation in Unity. You will be capable of making effective animations that express your artistic vision, as well as gaining an understanding of how and where you can expand your knowledge to the next level. But to reach that stage we'll begin, with the most basic concepts of animation—the groundwork for any understanding of animation.
In this article written by Nickolay Tsvetinov , author of the book Learning Reactive Programming with Java 8 , this article will present RxJava ( https://github.com/ReactiveX/RxJava ), an open source Java implementation of the reactive programming paradigm. Writing code using RxJava requires a different kind of thinking, but it will give you the power to create complex logic using simple pieces of well-structured code. In this article, we will cover: What reactive programming is Reasons to learn and use this style of programming Setting up RxJava and comparing it with familiar patterns and structures A simple example with RxJava
In this article by Cameron Buchanan , Terry Ip , Andrew Mabbitt , Benjamin May , and Dave Mound authors of the book Python Web Penetration Testing Cookbook , we're going to create scripts that encode attack strings, perform attacks, and time normal actions to normalize attack times.
In this article by Andrew Mallett , author of the book Learning RHEL Networking , we see on how to secure our network using the firewall daemon , that is, firewalld . The default user interface for netfilter , the kernel-based firewall, on RHEL7 is firewalld . Administrators now have a choice to use firewalld or iptables to manage firewalls. Underlying either process, we can still implement the kernel-based netfilter firewall. The frontend command to this new interface is firewall-cmd . The main benefit this offers is the ability to refresh the netfilter setting when the firewall is running. This is not possible with the iptables interface; additionally, we are able to use zone management. This enables us to have different firewall configurations, which depends on the network we are connected to. In this article, we will be cover the following topics: The firewall status Routing The zone management The source management Firewall rules using services Firewall rules using ports Masquerading and the network address translation Using rich rules Implementing direct rules Reverting to iptables
NumPy has a number of modules inherited from its predecessor, Numeric. Some of these packages have a SciPy counterpart, which may have fuller functionality. In this article by Ivan Idris author of the book NumPy: Beginner's Guide - Third Edition we will cover the following topics: The linalg package The fft package Random numbers Continuous and discrete distributions
In this article by Femi Anthony , author of the book, Mastering pandas , starts by taking a tour of NumPy ndarrays , a data structure not in pandas but NumPy. Knowledge of NumPy ndarrays is useful as it forms the foundation for the pandas data structures. Another key benefit of NumPy arrays is that they execute what is known as vectorized operations, which are operations that require traversing/looping on a Python array, much faster. In this article, I will present the material via numerous examples using IPython, a browser-based interface that allows the user to type in commands interactively to the Python interpreter.
In this article by Wilson da Rocha França , author of the book, MongoDB Data Modeling , we will cover documents and collections used in data modeling with MongoDB.
