Objektorientierte Programmierung
Komplexe Projekte solide strukturieren, tragfähige Designs erstellen, guten Code schreiben und wartbare Software liefern: Dafür brauchen Entwickler ein Repertoire, aus dem Objektorientierung nicht wegzudenken ist. In diesem Buch finden Sie alles, was Sie brauchen, um sich gründlich einzuarbeiten und die Prinzipien der OOP zur Basis Ihrer eigenen Arbeit zu machen. Die Autoren erläutern alle Themen anschaulich und verständlich anhand einer Vielzahl typischer Beispiele. Mit UML-Diagrammen und gut kommentierten Codebeispielen in den gängigsten objektorientierten Sprachen bringen sie Ihnen die Umsetzung nahe. Da so manches lehrreiche Detail erst auftaucht, wenn Sie konkrete Probleme lösen, ziehen sie viele praktische Anwendungsfälle heran und geben immer wieder Tipps, wie Sie bad smells vermeiden und sauberen Code schreiben. Anhand eines größeren Projekts bekommen Sie zudem einmal von Anfang bis Ende gezeigt, wie Sie objektorientierte Programmierung konsequent realisieren können. So profitieren Sie von der langjährigen Erfahrung der Autoren mit allen Aspekten der Entwicklung komplexer Software.

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. Gunnard also DJ’s Drum and Bass as Section31, Playing drums and baking bread (doughcode.com).1. Getting Started2. Setting up your development environment3. Devilbox4. Vagrant5. PHP 8 The Basics6.

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.

Pro Cryptography and Cryptanalysis with C++20
Develop strong skills and a passion for writing cryptography algorithms and security schemes/modules using C++ 20 and its new features. You will find the right methods of writing advanced cryptographic algorithms (such as, elliptic curve cryptography algorithms, lattice-based cryptography, searchable encryption, and homomorphic encryption), examine internal cryptographic mechanisms, and discover common ways in which the algorithms could be implemented and used correctly in practice.The authors avoid the complexities of the mathematical background by explaining its mathematical basis in terms that a programmer can easily understand. They show how “bad” cryptography creeps in during implementation and what “good” cryptography should look like. They do so by showing and comparing the advantages and disadvantages based on processing time, execution time, and reliability.WHAT YOU WILL LEARN* Understand where and why cryptography is used and how it gets misused * Discover what modern cryptography algorithms and methods are used for * Design and implement advanced cryptographic mechanisms * See how C++20 and its new features are impacting the future of implementing cryptographic algorithms* Practice the basics of public key cryptography, including ECDSA signatures and more* Find out how most of the algorithms can be brokenWHO THIS BOOK IS FORProfessional programmers, developers, and software engineers who are developing cryptography algorithms and security schemes/modules in C++.
