Intended for developers who are already familiar with the Apex language, and experienced Java and C# developers who are moving to Apex, this book starts where the Force.com documentation leaves off. Instead of trying to cover all of the features of the platform, Advanced Apex programming focuses entirely on the Apex language and core design patterns. You’ll learn how to truly think in Apex – to embrace limits and bulk patterns. You’ll see how to develop architectures for efficient and reliable trigger handling, and for asynchronous operations. You’ll discover that best practices differ radically depending on whether you are building software for a specific organization or for a managed package. And you’ll find approaches for incorporating testing and diagnostic code that can dramatically improve the reliability and deployment of Apex software, and reduce your lifecycle and support costs. Based on his experience both as a consultant and as architect of a major AppExchange package, Dan Appleman focuses on the real-world problems and issues that are faced by Apex developers every day, along with the obscure problems and surprises that can sneak up on you if you are unprepared.

    What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well.Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers: The type of networks now in use, from LANs, WANs and MANs to CANsThe OSI Model and the layers involved in sending data Hubs, repeaters, switches, and trunks in practice Auto negotiation and why it 's a common problem in network slowdowns Route maps, routing protocols, and switching algorithms in Cisco routers The resilient Ethernet -- how to make things truly redundant Cisco 6500 multi-layer switches and the Catalyst 3750 switch Telecom nomenclature -- why it 's different from the data world T1 and DS3 Firewall theory, designing access lists, authentication in Cisco devices Server load balancing technology Content switch module in action Designing QOS and what QOS does not do IP design and subnetting made easy The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.

    It also works beautifully with other open source tools, such as the MySQL database and the Apache web server. However, as more web sites are developed in PHP, they become targets for malicious attackers, and developers need to prepare for the attacks.Security is an issue that demands attention, given the growing frequency of attacks on web sites. Essential PHP Security explains the most common types of attacks and how to write code that isn't susceptible to them. By examining specific attacks and the techniques used to protect against them, you will have a deeper understanding and appreciation of the safeguards you are about to learn in this book.In the much-needed (and highly-requested) Essential PHP Security, each chapter covers an aspect of a web application (such as form processing, database programming, session management, and authentication). Chapters describe potential attacks with examples and then explain techniques to help you prevent those attacks.Topics covered include:Preventing cross-site scripting (XSS) vulnerabilitiesProtecting against SQL injection attacksComplicating session hijacking attemptsYou are in good hands with author Chris Shiflett, an internationally-recognized expert in the field of PHP security. Shiflett is also the founder and President of Brain Bulb, a PHP consultancy that offers a variety of services to clients around the world.

Here's straight talk on critical topics such as technical engineering basics, types of attack, specialized protection mechanisms, security psychology, policy, and more.

    Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.

    Building on the successful top-down approach of previous editions, this fourth edition continues with an early emphasis on application-layer paradigms and application programming interfaces, encouraging a hands-on experience with protocols and networking concepts.

    Targeting American utility companies, NATO, and electric grids in Eastern Europe, the strikes became ever more brazen, eventually leading to the first-ever blackouts triggered by hackers. They culminated in the summer of 2017 when malware known as NotPetya was unleashed, compromising, disrupting, and paralyzing some of the world's largest companies. At the attack's epicenter in Ukraine, ATMs froze. The railway and postal systems shut down. NotPetya spread around the world, inflicting an unprecedented ten billions of dollars in damage--the largest, most penetrating cyberattack the world had ever seen.The hackers behind these attacks are quickly gaining a reputation as the most dangerous team of cyberwarriors in the internet's history: Sandworm. Believed to be working in the service of Russia's military intelligence agency, they represent a persistent, highly skilled, state-sponsored hacking force, one whose talents are matched by their willingness to launch broad, unrestrained attacks on the most critical infrastructure of their adversaries. They target government and private sector, military and civilians alike.From WIRED senior writer Andy Greenberg comes Sandworm, the true story of the desperate hunt to identify and track those attackers. It considers the danger this force poses to our national stability and security. And as the Kremlin's role in manipulating foreign governments and sparking chaos globally comes into greater focus, Sandworm reveals the realities not just of Russia's global digital offensive, but of an era where warfare ceases to be waged on the battlefield--where the line between digital and physical conflict begins to blur, with world-shaking implications.

    They teach you how to make games. This book does not show you how to make games. It shows you how to take your game project to the finish line. Many game projects never make it beyond the alpha state.Game Development Success Is All About The Inner Game.Being a successful game developer does not (just) mean being a great programmer, a smart game designer or a gifted artist. It means dominating the inner game of game making. This separates the pros from the wannabes. It's the knowledge of how to stay focused, motivated and efficient during your game projects. It's the skillset of keeping things simple and avoiding misleading dreams of the next overnight success. Finally it's about thinking as a salesperson, not just as a designer, programmer or artist.
