Modern Front-end Architecture
Learn how to build front-end applications that can help you ship applications faster with fewer defects. Many software projects fail because they are not planned well, or lack organization. Applying strategies from other industries can help you create better software. This book explores the “mise en place” technique from cooking and reveals how you can apply it to the art of creating software.In many professional kitchens, the work of preparing a meal is divided and performed in workstations to help create the whole. You'll review the philosophy behind this and see how to leverage this approach in your code. You'll also learn to visualize your applications as a series of components and build parts of your application in isolation - just like a professional chef crafting each part of the meal.The book describes to how to structure your code base for reuse, and how to communicate the code’s intent to other developers. You’ll develop your components in isolation and test these building blocks for quality at a granular level. Then compose these components as building blocks in increasingly complicated features. Finally, you’ll apply some strategies not directly related to code to ensure maximum quality and efficiency.With Modern Front-end Architecture, developers of all levels will learn strategies that they and their teams can leverage to be more productive.WHAT YOU'LL LEARN* Structure an application as a series of components* Build a component library that others in an organization can leverage* Ensure quality and accessibility at a component level rather than a page or app level* Test code in a way that gives the maximum amount of confidence while providing an excellent developer experience* Automate repeatable tasksWHO THIS BOOK IS FORFront end developers looking to maximize their code for reuse, quality, and shipping features quickly. Experienced developers will pick up new techniques that they can apply to their code base. Less experienced developers will be able to start applications off on the right foot.RYAN LANCIAUX is an independent software developer based out of Ann Arbor, Michigan.

Game Theory for Cyber Deception
This book introduces game theory as a means to conceptualize, model, and analyze cyber deception. Drawing upon a collection of deception research from the past 10 years, the authors develop a taxonomy of six species of defensive cyber deception. Three of these six species are highlighted in the context of emerging problems such as privacy against ubiquitous tracking in the Internet of things (IoT), dynamic honeynets for the observation of advanced persistent threats (APTs), and active defense against physical denial-of-service (PDoS) attacks. Because of its uniquely thorough treatment of cyber deception, this book will serve as a timely contribution and valuable resource in this active field. The opening chapters introduce both cybersecurity in a manner suitable for game theorists and game theory as appropriate for cybersecurity professionals. Chapter Four then guides readers through the specific field of defensive cyber deception. A key feature of the remaining chapters is the development of a signaling game model for the species of leaky deception featured in honeypots and honeyfiles. This model is expanded to study interactions between multiple agents with varying abilities to detect deception. Game Theory for Cyber Deception will appeal to advanced undergraduates, graduate students, and researchers interested in applying game theory to cybersecurity. It will also be of value to researchers and professionals working on cybersecurity who seek an introduction to game theory.
Der Zufall in Physik, Informatik und Philosophie
Zufall als Fundament der Welt, aus der Buchreihe "Die blaue Stunde der Informatik".Der Zufall ist uns unheimlich. Wir dachten, es gäbe ihn nicht, hinter allem stehe Gott oder eine vernünftige Erklärung. Aber wir wissen heute: Es gibt ihn. Wir wissen, dass vieles dessen, was uns umgibt und das wir nicht durchschauen, trotzdem kausal abläuft. Anders als zu Zeiten der Aufklärung gedacht, ist der Zufall um uns eher die Regel als die gesetzmäßige Ordnung. Die Wolken sind Fraktale, die Wellen auf dem Meer sind eine reine Zufallsmaschinerie. Der Philosoph Charles Peirce hat genau in diesem Sinn noch vor Quanten- und Chaostheorie die fundamentale Bedeutung des Zufalls erkannt und der Lehre ihren Namen gegeben: Tychismus.Ohne Zufall gäbe es nichts Neues, kein Leben, keine Kreativität, keine Geschichte.Dieses Buch betrachtet den Zufall aus Sicht der Physik, der Informatik und der Philosophie. Es spannt den Bogen von der Antike zur Quantenphysik und zeigt, dass der Zufall fest in die Welt eingebaut ist und es sie ohne Zufall nicht gäbe.Dr. Walter Hehl ist vielseitiger Physiker und Autor recht verschiedener Bücher zu IT, Management, Religion, Philosophie und zur Geschichte der Wissenschaft. Sein Buch über Galilei erhielt 2019 den Preis der Woitschach-Stiftung für das beste kritische, aber faire Wissenschaftsbuch.

For each feature, the author includes real-life cases for its use and explains its benefits.WHAT YOU WILL LEARN* Utilize the new features of PHP 8 and modern development technologies* Work with the JIT compiler in PHP 8* Discover PHP 8 using real-life cases* Increase your available resources to become more valuable in your development teamWHO THIS BOOK IS FORExperienced PHP programmers new to PHP 8.GUNNARD ENGEBRETH began coding at the age of 11 through a “Learning BASIC” book given to him by his father. Technology was changing fast and Gunnard rode the wave from 1200 to 56k baud modems. Logging in to BBSs, Prodigy, Compuserve, Delphi and IRC he could see the world changing and he wanted to be a part of it. He soon got involved in the ansi/demo scene, making several application generators for many groups in the 90’s. Visual Basic was the next language of choice allowing him to develop “tools” for online systems such as AOL. This introduced many aspects of development, security and UI while they were still in their infancy. Once the WWW arrived via Mindspring in Atlanta, Ga. Gunnard quickly joined in the race for the web. Learning HTML, PERL and Linux (Slackware at the time) he began to build his skill-set which lead to a full-time Sysadmin position at the age of 20 (2000) at Activegrams/Silverpop. Gunnard has moved around the IT industry from SAN/NAS storage at IBM to custom Wordpress sites for marketing companies, but one thing has stayed the same, a passion for learning and problem solving.

MySQL Concurrency
Know how locks work in MySQL and how they relate to transactions. This book explains the major role that locks play in database systems, showing how locks are essential in allowing high-concurrency workloads. You will learn about lock access levels and lock granularities from the user level as well as table locks to record and gap locks. Most importantly, the book covers troubleshooting techniques when locking becomes a pain point.Several of the lock types in MySQL have a duration of a transaction. For this reason, it is important to understand how transactions work. This book covers the basics of transactions as well as transaction isolation levels and how they affect locking. The book is meant to be your go-to resource for solving locking contention and similar problems in high-performance MySQL database applications.Detecting locking issues when they occur is the first key to resolving such issues. MySQL Concurrency provides techniques for detecting locking issues such as contention. The book shows how to analyze locks that are causing contention to see why those locks are in place. A collection of six comprehensive case studies combine locking and transactional theory with realistic lock conflicts. The case studies walk you through the symptoms to look for in order to identify which issue you are facing, the cause of the conflict, its analysis, solution, and how to prevent the issue in the future.WHAT YOU WILL LEARN* Understand which lock types exist in MySQL and how they are used* Choose the best transaction isolation level for a given transaction* Detect and analyze lock contention when it occurs* Reduce locking issues in your applications* Resolve deadlocks between transactions* Resolve InnoDB record-level locking issues* Resolve issues from metadata and schema locksWHO THIS BOOK IS FORDatabase administrators and SQL developers who are familiar with MySQL and want to gain a better understanding of locking and transactions as well as how to work with them. While some experience with MySQL is required, no prior knowledge of locks and transactions is needed.JESPER WISBORG KROGH has worked with MySQL databases since 2006 both as a SQL developer and a database administrator, and for more than eight years as part of the Oracle MySQL Support team. He currently works as a database reliability engineer for Okta. He has spoken at MySQL Connect and Oracle OpenWorld on several occasions. In addition to his books, Jesper regularly blogs on MySQL topics and has authored approximately 800 documents in the Oracle Knowledge Base.

The Alignment Problem
'Vital reading. This is the book on artificial intelligence we need right now.' Mike Krieger, cofounder of InstagramArtificial intelligence is rapidly dominating every aspect of our modern lives influencing the news we consume, whether we get a mortgage, and even which friends wish us happy birthday. But as algorithms make ever more decisions on our behalf, how do we ensure they do what we want? And fairly?This conundrum - dubbed 'The Alignment Problem' by experts - is the subject of this timely and important book. From the AI program which cheats at computer games to the sexist algorithm behind Google Translate, bestselling author Brian Christian explains how, as AI develops, we rapidly approach a collision between artificial intelligence and ethics. If we stand by, we face a future with unregulated algorithms that propagate our biases - and worse - violate our most sacred values. Urgent and fascinating, this is an accessible primer to the most important issue facing AI researchers today.Brian Christian is the author of the acclaimed bestsellersThe Most Human Human andAlgorithms to Live By, which have been translated into nineteen languages. A visiting scholar at the University of California, Berkeley, he lives in San Francisco.
Data Analytics in Bioinformatics
Machine learning techniques are increasingly being used to address problems in computational biology and bioinformatics. Novel machine learning computational techniques to analyze high throughput data in the form of sequences, gene and protein expressions, pathways, and images are becoming vital for understanding diseases and future drug discovery. Machine learning techniques such as Markov models, support vector machines, neural networks, and graphical models have been successful in analyzing life science data because of their capabilities in handling randomness and uncertainty of data noise and in generalization. Machine Learning in Bioinformatics compiles recent approaches in machine learning methods and their applications in addressing contemporary problems in bioinformatics approximating classification and prediction of disease, feature selection, dimensionality reduction, gene selection and classification of microarray data and many more.

Patterns in the Machine
Discover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors’ experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability.This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today’s embedded projects.After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code.WHAT YOU WILL LEARN* Incorporate automated unit testing into an embedded project* Design and build functional simulators for an embedded project* Write production-quality software when hardware is not available* Use the Data Model architectural pattern to create a highly decoupled design and implementation* Understand the importance of defining the software architecture before implementation starts and how to do it* Discover why documentation is essential for an embedded project* Use finite state machines in embedded projectsWHO THIS BOOK IS FORMid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.John Taylor has been an embedded developer for over 29 years.
