Secure Web Application Development
Cyberattacks are becoming more commonplace and the Open Web Application Security Project (OWASP), estimates 94% of sites have flaws in their access control alone. Attacks evolve to work around new defenses, and defenses must evolve to remain effective. Developers need to understand the fundamentals of attacks and defenses in order to comprehend new techniques as they become available. This book teaches you how to write secure web applications.The focus is highlighting how hackers attack applications along with a broad arsenal of defenses. This will enable you to pick appropriate techniques to close vulnerabilities while still providing users with their needed functionality.Topics covered include:* A framework for deciding what needs to be protected and how strongly* Configuring services such as databases and web servers* Safe use of HTTP methods such as GET, POST, etc, cookies and use of HTTPS* Safe REST APIs* Server-side attacks and defenses such as injection and cross-site scripting* Client-side attacks and defenses such as cross-site request forgery* Security techniques such as CORS, CSP* Password management, authentication and authorization, including OAuth2* Best practices for dangerous operations such as password change and reset* Use of third-party components and supply chain security (Git, CI/CD etc)WHAT YOU'LL LEARN** Review the defenses that can used to prevent attacks* Model risks to better understand what to defend and how* Choose appropriate techniques to defend against attacks* Implement defenses in Python/Django applicationsWHO THIS BOOK IS FOR* Developers who already know how to build web applications but need to know more about security* Non-professional software engineers, such as scientists, who must develop web tools and want to make their algorithms available to a wider audience.* Engineers and managers who are responsible for their product/company technical security policyMATTHEW BAKER is the Head of Scientific Software and Data Management at ETH Zurich, Switzerland’s leading science and technology university, He leads a team of engineers developing custom software to support STEM research projects, as well as teaches computer science short courses.

How to Create a Web3 Startup
Web3 is the next evolution for the World Wide Web based on Blockchain technology. This book will equip entrepreneurs with the best preparation for the megatrend of Web3 by reviewing its core concepts such as DAOs, tokens, dApps, and Ethereum.With Web2, much of the valuable data and wealth has been concentrated with a handful of mega tech operators like Apple, Facebook, Google and Amazon. This has made it difficult for startups to get an edge. It has also meant that users have had little choice but to give up their value data for free. Web3 aims to upend this model using a decentralized approach that is on the blockchain and crypto. This allows for users to become stakeholders in the ecosystem.Along with exploring core concepts of Web3 like DAOs, tokens, dApps, and Ethereum, this book will also examine the main categories that are poised for enormous opportunities. They include infrastructure, consumer apps, enterpriseapps, and the metaverse. For each of these, I will have use cases of successful companies. How To Create a Web3 Startup covers the unique funding strategies, the toolsets needed, the talent required, the go-to-market approaches, and challenges faced.WHAT YOU'LL LEARN* Work with the dev stack components* Examine the success factors for infrastructure, consumer, enterprise, verticals, and the Metaverse* Understand the risks of Web3, like the regulatory structure and security breachesWHO THIS BOOK IS FORStartup entrepreneurs and those looking to work in the Web3 industry.Tom Taulli has been developing software since the 1980s.

Die Geheimnisse von Monkey Island
Unterhaltsam, kurzweilig, informativ: „Die Geheimnisse von Monkey Island – Auf Kapertour mit Pixel-Piraten“ ist DAS Buch für Fans der legendären Point’n’Click-Adventure-Reihe „Monkey Island“. Das Buch erschien zeitgleich zum neuen Teil von Monkey Island, der erstmals nach 30 Jahren wieder vom ursprünglichen Entwickler Ron Gilbert kreiert wurde."Macht, was ihr wollt, aber macht coole Sachen!" - George Lucas am 1. Mai 1982. Das war das einzige Ziel, das George Lucas seinen zwanzig jungen, ehrgeizigen, lustigen und schlecht frisierten Game-Designern als Rahmen für die Entwicklung von eigenen Computerspielen setzte. Lucasfilm Games und später LucasArts wurde in der Folgezeit zu einer legendären Spieleschmiede, auch durch die Veröffentlichung von The Secret of Monkey Island™ im Jahr 1990. Das bekannteste Point‘n‘Click-Adventure verdankt seinen legendären Ruf seiner herrlich anachronistischen Welt voller bunter Piraten und seinem von Monty Python inspirierten Humor, aber auch schlicht und einfach der Tatsache, dass es ein komplettes Genre revolutioniert hat. Dieses Buch ist eine Hommage an die Abenteuer von Guybrush Threepwood, einem genialen Piraten. Aber es möchte Ihnen auch in vielen Details schildern, wie Monkey Island durch seine einzigartige Erzählkunst zum Meilenstein in der Videospielgeschichte wurde.Darüber hinaus bietet es die Gelegenheit, auf die turbulente Historie von LucasArts und Telltale Games zurückzublicken, Rezepte für Voodoo-Grog zu entdecken, interaktive Piratenreggae-Songs zu lernen, auf einer mondänen Party unter 40-jährigen Geeks zu glänzen und Sprüche zu erkunden, die so scharf wie ein Entermesser sind (nützlich für Duelle oder Geburtstagsfeiern).

Building Quality Shaders for Unity®
Understand what shaders are and what they’re used for: Shaders are often seen as mystical and difficult to develop, even by skilled programmers, artists, and developers from other game design disciplines. This book dispels that idea by building up your shader knowledge in stages, starting with fundamental shader mathematics and how shader development mindset differs from other types of art and programming, and slowly delves into topics such as vertex and fragment shaders, lighting, depth-based effects, texture mapping, and Shader Graph.This book presents each of these topics with a comprehensive breakdown, the required theory, and some practical applications for the techniques learned during each chapter. The HLSL (High Level Shading Language) code and Shader Graphs will be provided for each relevant section, as well as plenty of screenshots.By the end of this book, you will have a good understanding of the shader development pipeline and you will be fully equipped to start making your own aesthetic and performant shader effects for your own games!YOU WILL LEARN TO• Use shaders across Unity’s rendering pipelines• Write shaders and modify their behavior with C# scripting• Use Shader Graph for codeless development• Understand the important math behind shaders, particularly space transformations• Profile the performance of shaders to identify optimization targetsWHO IS THIS BOOK FORThis book is intended for beginners to shader development, or readers who may want to make the jump from shader code to Shader Graph. It will also include a section on shader examples for those who already know the fundamentals of shaders and are looking for specific use cases. Daniel Ilett is an ambitious and motivated PhD student at the University of Warwick. He is a passionate game developer, specialising in shaders and technical art.

Modern C Up and Running
Learn how to program in modern C, from the basics through the advanced topics required for proficiency. This book is the fastest path to C fluency for anyone experienced in a general-purpose programming language. From start to finish, code examples highlight the idioms and best practices behind efficient, robust programs in a variety of areas.The book opens with a thorough coverage of syntax, built-in data types and operations, and program structure. C has quirks and presents challenges, which are covered in detail. The coverage of advanced features is what sets this book apart from others. Among the advanced topics covered are floating-point representation in the IEEE 754 standard; embedded assembly language in C code for overflow detection; regular expressions, assertions, and internationalization; WebAssembly through C; and software libraries for C and other clients.Memory efficiency and safety are the two major challenges in C programming, and you’ll explore these challenges through a series of C examples. Arrays and structures, which are the means to high-level data representation, are covered in connection with pointers, which provide efficiency. The book again uses code examples in covering networking and wire-level security; concurrency (multiprocessing and multithreading); instruction-level parallelism; and interprocess communication through shared memory and files, pipes, message queues, and signals.Many books introduce C, but few also explain how to use it properly and optimally. Essential C does just that.WHAT YOU'LL LEARN* Accelerate your path to C mastery with this book for experienced programmers* Refresh your approach to program structure and data types* Dive into aggregates and pointers using modern C language* Revisit storage classes and scope* Dive into concurrency (multiprocessing and multithreading) and instruction-level parallelism* Finish with regular expressions, assertions, signals, locales and moreWHO THIS BOOK IS FORProfessional programmers or software developers who has prior experience with C or in general wanting an accelerated learning guide to modern C programming language.Martin Kalin has a Ph.D. from Northwestern University and is a professor in the College of Computing and Digital Media at DePaul University. He has co-written a series of books on C and C++ and written a book on Java for programmers. He enjoys commercial programming and has co-developed large distributed systems in process scheduling and product configuration.1. Program Structure2. Basic Data Types3. Aggregates and Pointers4.
