| facebook system design questions: Grokking the System Design Interview Design Gurus, 2021-12-18 This book (also available online at www.designgurus.org) by Design Gurus has helped 60k+ readers to crack their system design interview (SDI). System design questions have become a standard part of the software engineering interview process. These interviews determine your ability to work with complex systems and the position and salary you will be offered by the interviewing company. Unfortunately, SDI is difficult for most engineers, partly because they lack experience developing large-scale systems and partly because SDIs are unstructured in nature. Even engineers who've some experience building such systems aren't comfortable with these interviews, mainly due to the open-ended nature of design problems that don't have a standard answer. This book is a comprehensive guide to master SDIs. It was created by hiring managers who have worked for Google, Facebook, Microsoft, and Amazon. The book contains a carefully chosen set of questions that have been repeatedly asked at top companies. What's inside? This book is divided into two parts. The first part includes a step-by-step guide on how to answer a system design question in an interview, followed by famous system design case studies. The second part of the book includes a glossary of system design concepts. Table of Contents First Part: System Design Interviews: A step-by-step guide.

| facebook system design questions: Principles of Computer System Design Jerome H. Saltzer, M. Frans Kaashoek, 2009-05-21 Principles of Computer System Design is the first textbook to take a principles-based approach to the computer system design. It identifies, examines, and illustrates fundamental concepts in computer system design that are common across operating systems, networks, database systems, distributed systems, programming languages, software engineering, security, fault tolerance, and architecture.Through carefully analyzed case studies from each of these disciplines, it demonstrates how to apply these concepts to tackle practical system design problems. To support the focus on design, the text identifies and explains abstractions that have proven successful in practice such as remote procedure call, client/service organization, file systems, data integrity, consistency, and authenticated messages. Most computer systems are built using a handful of such abstractions. The text describes how these abstractions are implemented, demonstrates how they are used in different systems, and prepares the reader to apply them in future designs.The book is recommended for junior and senior undergraduate students in Operating Systems, Distributed Systems, Distributed Operating Systems and/or Computer Systems Design courses; and professional computer systems designers. - Concepts of computer system design guided by fundamental principles - Cross-cutting approach that identifies abstractions common to networking, operating systems, transaction systems, distributed systems, architecture, and software engineering - Case studies that make the abstractions real: naming (DNS and the URL); file systems (the UNIX file system); clients and services (NFS); virtualization (virtual machines); scheduling (disk arms); security (TLS) - Numerous pseudocode fragments that provide concrete examples of abstract concepts - Extensive support. The authors and MIT OpenCourseWare provide on-line, free of charge, open educational resources, including additional chapters, course syllabi, board layouts and slides, lecture videos, and an archive of lecture schedules, class assignments, and design projects |
| facebook system design questions: Building Mobile Apps at Scale Gergely Orosz, 2021-04-06 While there is a lot of appreciation for backend and distributed systems challenges, there tends to be less empathy for why mobile development is hard when done at scale. This book collects challenges engineers face when building iOS and Android apps at scale, and common ways to tackle these. By scale, we mean having numbers of users in the millions and being built by large engineering teams. For mobile engineers, this book is a blueprint for modern app engineering approaches. For non-mobile engineers and managers, it is a resource with which to build empathy and appreciation for the complexity of world-class mobile engineering. The book covers iOS and Android mobile app challenges on these dimensions: Challenges due to the unique nature of mobile applications compared to the web, and to the backend. App complexity challenges. How do you deal with increasingly complicated navigation patterns? What about non-deterministic event combinations? How do you localize across several languages, and how do you scale your automated and manual tests? Challenges due to large engineering teams. The larger the mobile team, the more challenging it becomes to ensure a consistent architecture. If your company builds multiple apps, how do you balance not rewriting everything from scratch while moving at a fast pace, over waiting on centralized teams? Cross-platform approaches. The tooling to build mobile apps keeps changing. New languages, frameworks, and approaches that all promise to address the pain points of mobile engineering keep appearing. But which approach should you choose? Flutter, React Native, Cordova? Native apps? Reuse business logic written in Kotlin, C#, C++ or other languages? What engineering approaches do world-class mobile engineering teams choose in non-functional aspects like code quality, compliance, privacy, compliance, or with experimentation, performance, or app size? |

| facebook system design questions: A Philosophy of Software Design John K. Ousterhout, 2021 This book addresses the topic of software design: how to decompose complex software systems into modules (such as classes and methods) that can be implemented relatively independently. The book first introduces the fundamental problem in software design, which is managing complexity. It then discusses philosophical issues about how to approach the software design process and it presents a collection of design principles to apply during software design. The book also introduces a set of red flags that identify design problems. You can apply the ideas in this book to minimize the complexity of large software systems, so that you can write software more quickly and cheaply.--Amazon. |
| facebook system design questions: Understanding by Design Grant P. Wiggins, Jay McTighe, 2005 What is understanding and how does it differ from knowledge? How can we determine the big ideas worth understanding? Why is understanding an important teaching goal, and how do we know when students have attained it? How can we create a rigorous and engaging curriculum that focuses on understanding and leads to improved student performance in today's high-stakes, standards-based environment? Authors Grant Wiggins and Jay McTighe answer these and many other questions in this second edition of Understanding by Design. Drawing on feedback from thousands of educators around the world who have used the UbD framework since its introduction in 1998, the authors have greatly revised and expanded their original work to guide educators across the K-16 spectrum in the design of curriculum, assessment, and instruction. With an improved UbD Template at its core, the book explains the rationale of backward design and explores in greater depth the meaning of such key ideas as essential questions and transfer tasks. Readers will learn why the familiar coverage- and activity-based approaches to curriculum design fall short, and how a focus on the six facets of understanding can enrich student learning. With an expanded array of practical strategies, tools, and examples from all subject areas, the book demonstrates how the research-based principles of Understanding by Design apply to district frameworks as well as to individual units of curriculum. Combining provocative ideas, thoughtful analysis, and tested approaches, this new edition of Understanding by Design offers teacher-designers a clear path to the creation of curriculum that ensures better learning and a more stimulating experience for students and teachers alike. |
| facebook system design questions: Antisocial Media Siva Vaidhyanathan, 2018-05-15 A fully updated paperback edition that includes coverage of the key developments of the past two years, including the political controversies that swirled around Facebook with increasing intensity in the Trump era. If you wanted to build a machine that would distribute propaganda to millions of people, distract them from important issues, energize hatred and bigotry, erode social trust, undermine respectable journalism, foster doubts about science, and engage in massive surveillance all at once, you would make something a lot like Facebook. Of course, none of that was part of the plan. In this fully updated paperback edition of Antisocial Media, including a new chapter on the increasing recognition of--and reaction against--Facebook's power in the last couple of years, Siva Vaidhyanathan explains how Facebook devolved from an innocent social site hacked together by Harvard students into a force that, while it may make personal life just a little more pleasurable, makes democracy a lot more challenging. It's an account of the hubris of good intentions, a missionary spirit, and an ideology that sees computer code as the universal solvent for all human problems. And it's an indictment of how social media has fostered the deterioration of democratic culture around the world, from facilitating Russian meddling in support of Trump's election to the exploitation of the platform by murderous authoritarians in Burma and the Philippines. Both authoritative and trenchant, Antisocial Media shows how Facebook's mission went so wrong. |

| facebook system design questions: Zucked Roger McNamee, 2019-02-05 One of the Financial Times' Best Business Books of 2019 The New York Times bestseller about a noted tech venture capitalist, early mentor to Mark Zuckerberg, and Facebook investor, who wakes up to the serious damage Facebook is doing to our society—and sets out to try to stop it. If you had told Roger McNamee even three years ago that he would soon be devoting himself to stopping Facebook from destroying our democracy, he would have howled with laughter. He had mentored many tech leaders in his illustrious career as an investor, but few things had made him prouder, or been better for his fund's bottom line, than his early service to Mark Zuckerberg. Still a large shareholder in Facebook, he had every good reason to stay on the bright side. Until he simply couldn't. Zucked is McNamee's intimate reckoning with the catastrophic failure of the head of one of the world's most powerful companies to face up to the damage he is doing. It's a story that begins with a series of rude awakenings. First there is the author's dawning realization that the platform is being manipulated by some very bad actors. Then there is the even more unsettling realization that Zuckerberg and Sheryl Sandberg are unable or unwilling to share his concerns, polite as they may be to his face. And then comes the election of Donald Trump, and the emergence of one horrific piece of news after another about the malign ends to which the Facebook platform has been put. To McNamee's shock, even still Facebook's leaders duck and dissemble, viewing the matter as a public relations problem. Now thoroughly alienated, McNamee digs into the issue, and fortuitously meets up with some fellow travelers who share his concern, and help him sharpen its focus. Soon he and a dream team of Silicon Valley technologists are charging into the fray, to raise consciousness about the existential threat of Facebook, and the persuasion architecture of the attention economy more broadly—to our public health and to our political order. Zucked is both an enthralling personal narrative and a masterful explication of the forces that have conspired to place us all on the horns of this dilemma. This is the story of a company and its leadership, but it's also a larger tale of a business sector unmoored from normal constraints, just at a moment of political and cultural crisis, the worst possible time to be given new tools for summoning the darker angels of our nature and whipping them into a frenzy. Like Jimmy Stewart in Rear Window, Roger McNamee happened to be in the right place to witness a crime, and it took him some time to make sense of what he was seeing and what we ought to do about it. The result of that effort is a wise, hard-hitting, and urgently necessary account that crystallizes the issue definitively for the rest of us. |

| facebook system design questions: Introduction to Embedded Systems, Second Edition Edward Ashford Lee, Sanjit Arunkumar Seshia, 2017-01-06 An introduction to the engineering principles of embedded systems, with a focus on modeling, design, and analysis of cyber-physical systems. The most visible use of computers and software is processing information for human consumption. The vast majority of computers in use, however, are much less visible. They run the engine, brakes, seatbelts, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They command robots on a factory floor, power generation in a power plant, processes in a chemical plant, and traffic lights in a city. These less visible computers are called embedded systems, and the software they run is called embedded software. The principal challenges in designing and analyzing embedded systems stem from their interaction with physical processes. This book takes a cyber-physical approach to embedded systems, introducing the engineering concepts underlying embedded systems as a technology and as a subject of study. The focus is on modeling, design, and analysis of cyber-physical systems, which integrate computation, networking, and physical processes. The second edition offers two new chapters, several new exercises, and other improvements. The book can be used as a textbook at the advanced undergraduate or introductory graduate level and as a professional reference for practicing engineers and computer scientists. Readers should have some familiarity with machine structures, computer programming, basic discrete mathematics and algorithms, and signals and systems. |

| facebook system design questions: Understanding Distributed Systems, Second Edition Roberto Vitillo, 2022-02-23 Learning to build distributed systems is hard, especially if they are large scale. It's not that there is a lack of information out there. You can find academic papers, engineering blogs, and even books on the subject. The problem is that the available information is spread out all over the place, and if you were to put it on a spectrum from theory to practice, you would find a lot of material at the two ends but not much in the middle. That is why I decided to write a book that brings together the core theoretical and practical concepts of distributed systems so that you don't have to spend hours connecting the dots. This book will guide you through the fundamentals of large-scale distributed systems, with just enough details and external references to dive deeper. This is the guide I wished existed when I first started out, based on my experience building large distributed systems that scale to millions of requests per second and billions of devices. If you are a developer working on the backend of web or mobile applications (or would like to be!), this book is for you. When building distributed applications, you need to be familiar with the network stack, data consistency models, scalability and reliability patterns, observability best practices, and much more. Although you can build applications without knowing much of that, you will end up spending hours debugging and re-architecting them, learning hard lessons that you could have acquired in a much faster and less painful way. However, if you have several years of experience designing and building highly available and fault-tolerant applications that scale to millions of users, this book might not be for you. As an expert, you are likely looking for depth rather than breadth, and this book focuses more on the latter since it would be impossible to cover the field otherwise. The second edition is a complete rewrite of the previous edition. Every page of the first edition has been reviewed and where appropriate reworked, with new topics covered for the first time. |
| facebook system design questions: Designing Data-Intensive Applications Martin Kleppmann, 2017-03-16 Data is at the center of many challenges in system design today. Difficult issues need to be figured out, such as scalability, consistency, reliability, efficiency, and maintainability. In addition, we have an overwhelming variety of tools, including relational databases, NoSQL datastores, stream or batch processors, and message brokers. What are the right choices for your application? How do you make sense of all these buzzwords? In this practical and comprehensive guide, author Martin Kleppmann helps you navigate this diverse landscape by examining the pros and cons of various technologies for processing and storing data. Software keeps changing, but the fundamental principles remain the same. With this book, software engineers and architects will learn how to apply those ideas in practice, and how to make full use of data in modern applications. Peer under the hood of the systems you already use, and learn how to use and operate them more effectively Make informed decisions by identifying the strengths and weaknesses of different tools Navigate the trade-offs around consistency, scalability, fault tolerance, and complexity Understand the distributed systems research upon which modern databases are built Peek behind the scenes of major online services, and learn from their architectures |
| facebook system design questions: Window Shopping Tessa Bailey, 2022-01-25 Two weeks before Christmas and all through Manhattan, shop windows are decorated in red and green satin. I'm standing alone in front of the famous Vivant department store, when a charming man named Aiden asks my opinion of the décor. It's a tragedy in tinsel, I say, unable to lie. He asks for a better idea with a twinkle in his eye. Did I know he owned the place? No. He put me on the spot. Now I'm working for that man, trying to ignore that he's hot. But as a down on her luck girl with a difficult past, I know an opportunity when I see one - and I have to make it last. I'll put my heart and soul into dressing his holiday windows. I'll work without stopping. And when we lose the battle with temptation, I'll try and remember I'm just window shopping--back cover. |
| facebook system design questions: Patterns of Enterprise Application Architecture Martin Fowler, 2012-03-09 The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform. This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts. Armed with this book, you will have the knowledge necessary to make important architectural decisions about building an enterprise application and the proven patterns for use when building them. The topics covered include · Dividing an enterprise application into layers · The major approaches to organizing business logic · An in-depth treatment of mapping between objects and relational databases · Using Model-View-Controller to organize a Web presentation · Handling concurrency for data that spans multiple transactions · Designing distributed object interfaces |

| facebook system design questions: The Moment of Lift Melinda Gates, 2019-04-23 NEW YORK TIMES BESTSELLER “In her book, Melinda tells the stories of the inspiring people she’s met through her work all over the world, digs into the data, and powerfully illustrates issues that need our attention—from child marriage to gender inequity in the workplace.” — President Barack Obama “The Moment of Lift is an urgent call to courage. It changed how I think about myself, my family, my work, and what’s possible in the world. Melinda weaves together vulnerable, brave storytelling and compelling data to make this one of those rare books that you carry in your heart and mind long after the last page.” — Brené Brown, Ph.D., author of the New York Times #1 bestseller Dare to Lead “Melinda Gates has spent many years working with women around the world. This book is an urgent manifesto for an equal society where women are valued and recognized in all spheres of life. Most of all, it is a call for unity, inclusion and connection. We need this message more than ever.” — Malala Yousafzai Melinda Gates's book is a lesson in listening. A powerful, poignant, and ultimately humble call to arms. — Tara Westover, author of the New York Times #1 bestseller Educated A debut from Melinda Gates, a timely and necessary call to action for women's empowerment. “How can we summon a moment of lift for human beings – and especially for women? Because when you lift up women, you lift up humanity.” For the last twenty years, Melinda Gates has been on a mission to find solutions for people with the most urgent needs, wherever they live. Throughout this journey, one thing has become increasingly clear to her: If you want to lift a society up, you need to stop keeping women down. In this moving and compelling book, Melinda shares lessons she’s learned from the inspiring people she’s met during her work and travels around the world. As she writes in the introduction, “That is why I had to write this book—to share the stories of people who have given focus and urgency to my life. I want all of us to see ways we can lift women up where we live.” Melinda’s unforgettable narrative is backed by startling data as she presents the issues that most need our attention—from child marriage to lack of access to contraceptives to gender inequity in the workplace. And, for the first time, she writes about her personal life and the road to equality in her own marriage. Throughout, she shows how there has never been more opportunity to change the world—and ourselves. Writing with emotion, candor, and grace, she introduces us to remarkable women and shows the power of connecting with one another. When we lift others up, they lift us up, too. |

| facebook system design questions: This Chair Rocks Ashton Applewhite, 2019-03-05 Author, activist, and TED speaker Ashton Applewhite has written a rousing manifesto calling for an end to discrimination and prejudice on the basis of age. In our youth obsessed culture, we’re bombarded by media images and messages about the despairs and declines of our later years. Beauty and pharmaceutical companies work overtime to convince people to purchase products that will retain their youthful appearance and vitality. Wrinkles are embarrassing. Gray hair should be colored and bald heads covered with implants. Older minds and bodies are too frail to keep up with the pace of the modern working world and olders should just step aside for the new generation. Ashton Applewhite once held these beliefs too until she realized where this prejudice comes from and the damage it does. Lively, funny, and deeply researched, This Chair Rocks traces her journey from apprehensive boomer to pro-aging radical, and in the process debunks myth after myth about late life. Explaining the roots of ageism in history and how it divides and debases, Applewhite examines how ageist stereotypes cripple the way our brains and bodies function, looks at ageism in the workplace and the bedroom, exposes the cost of the all-American myth of independence, critiques the portrayal of elders as burdens to society, describes what an all-age-friendly world would look like, and offers a rousing call to action. It’s time to create a world of age equality by making discrimination on the basis of age as unacceptable as any other kind of bias. Whether you’re older or hoping to get there, this book will shake you by the shoulders, cheer you up, make you mad, and change the way you see the rest of your life. Age pride! “Wow. This book totally rocks. It arrived on a day when I was in deep confusion and sadness about my age. Everything about it, from my invisibility to my neck. Within four or five wise, passionate pages, I had found insight, illumination, and inspiration. I never use the word empower, but this book has empowered me.” —Anne Lamott, New York Times bestselling author |
| facebook system design questions: The Age of Surveillance Capitalism Shoshana Zuboff, 2019-01-15 The challenges to humanity posed by the digital future, the first detailed examination of the unprecedented form of power called surveillance capitalism, and the quest by powerful corporations to predict and control our behavior. In this masterwork of original thinking and research, Shoshana Zuboff provides startling insights into the phenomenon that she has named surveillance capitalism. The stakes could not be higher: a global architecture of behavior modification threatens human nature in the twenty-first century just as industrial capitalism disfigured the natural world in the twentieth. Zuboff vividly brings to life the consequences as surveillance capitalism advances from Silicon Valley into every economic sector. Vast wealth and power are accumulated in ominous new behavioral futures markets, where predictions about our behavior are bought and sold, and the production of goods and services is subordinated to a new means of behavioral modification. The threat has shifted from a totalitarian Big Brother state to a ubiquitous digital architecture: a Big Other operating in the interests of surveillance capital. Here is the crucible of an unprecedented form of power marked by extreme concentrations of knowledge and free from democratic oversight. Zuboff's comprehensive and moving analysis lays bare the threats to twenty-first century society: a controlled hive of total connection that seduces with promises of total certainty for maximum profit -- at the expense of democracy, freedom, and our human future. With little resistance from law or society, surveillance capitalism is on the verge of dominating the social order and shaping the digital future -- if we let it. |
| facebook system design questions: The Bullet Journal Method Ryder Carroll, 2021-12 THE NEW YORK TIMES BESTSELLER Transform your life using the Bullet Journal Method, the revolutionary organisational system and worldwide phenomenon. The Bullet Journal Method will undoubtedly transform your life, in more ways than you can imagine' Hal Elrod, author of The Miracle Morning In his long-awaited first book, Ryder Carroll, the creator of the enormously popular Bullet Journal organisational system, explains how to use his method to: * TRACK YOUR PAST: using nothing more than a pen and paper, create a clear, comprehensive, and organised record of your thoughts and goals. * ORDER YOUR PRESENT: find daily calm by prioritising and minimising your workload and tackling your to-do list in a more mindful and productive way. * PLAN YOUR FUTURE: establish and appraise your short-term and long-term goals, plan more complex projects simply and effectively, and live your life with meaning and purpose. Like many of us, Ryder Carroll tried everything to get organised - countless apps, systems, planners, you name it. Nothing really worked. Then he invented his own simple system that required only pen and paper, which he found both effective and calming. He shared his method with a few friends, and before long he had a worldwide viral movement. The system combines elements of a wishlist, a to-do list, and a diary. It helps you identify what matters and set goals accordingly. By breaking long-term goals into small actionable steps, users map out an approachable path towards continual improvement, allowing them to stay focused despite the crush of incoming demands. But this is much more than a time management book. It's also a manifesto for what Ryder calls intentional living: making sure that your beliefs and actions align. Even if you already use a Bullet Journal, this book gives you new exercises to become more calm and focused, new insights on how to prioritise well, and a new awareness of the power of analogue tools in a digital world. *** This book has been printed with three different colour designs, black, Nordic blue and emerald.
