In Pomodoro Technique Illustrated, Staffan N teberg shows you how to organize your work to accomplish more in less time. There's no need for expensive software or fancy planners. You can get started with nothing more than a piece of paper, a pencil, and a kitchen timer. You have so much you need to accomplish today. Your list is a mile long and you find yourself getting interrupted every other minute. You'd like to tell everyone to leave you alone, but most of the interruptions are coming from you! You think of a phone call you need to make or a web site you need to check and before you know it you're answering email, checking twitter, and finding a million other things to occupy your time. You need to focus---really focus. The Pomodoro Technique puts you back in charge of your day. You'll apply successful techniques from software engineering to identify what you should be doing today and to help you achieve your goals. Your mind won't wander when it is fully engaged in short bursts of focused activity. Learn to work less and accomplish more using nothing more than paper, pencil, and a simple kitchen timer. Set the timer and start on your next Pomodoro. When the bell rings take a break. This personal approach to timeboxing is at the core of the Pomodoro technique and this book is filled with advice on how get started and how to tailor it to your own needs.

    Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on Linux(R) and Unix(R) performance, while illuminating performance issues that are relevant to all operating systems. You'll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based Ubuntu(R), Fedora(R), CentOS, and the illumos-based Joyent(R) SmartOS(TM) and OmniTI OmniOS(R). He systematically covers modern systems performance, including the "traditional" analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the "unknown unknowns" of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish. Coverage includes - Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques - Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf - Kernel internals: uncovering what the OS is doing - Using system observability tools, interfaces, and frameworks - Understanding and monitoring application performance - Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling - Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators - File system I/O, including caching - Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O - Network-related performance issues: protocols, sockets, interfaces, and physical connections - Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing - Benchmarking: getting accurate results and avoiding common mistakes This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Gregg's extensive instructional experience.

    Inspired by forensic psychology methods, you'll learn strategies to predict the future of your codebase, assess refactoring direction, and understand how your team influences the design. With its unique blend of forensic psychology and code analysis, this book arms you with the strategies you need, no matter what programming language you use.Software is a living entity that's constantly changing. To understand software systems, we need to know where they came from and how they evolved. By mining commit data and analyzing the history of your code, you can start fixes ahead of time to eliminate broken designs, maintenance issues, and team productivity bottlenecks. In this book, you'll learn forensic psychology techniques to successfully maintain your software. You'll create a geographic profile from your commit data to find hotspots, and apply temporal coupling concepts to uncover hidden relationships between unrelated areas in your code. You'll also measure the effectiveness of your code improvements. You'll learn how to apply these techniques on projects both large and small. For small projects, you'll get new insights into your design and how well the code fits your ideas. For large projects, you'll identify the good and the fragile parts.Large-scale development is also a social activity, and the team's dynamics influence code quality. That's why this book shows you how to uncover social biases when analyzing the evolution of your system. You'll use commit messages as eyewitness accounts to what is really happening in your code. Finally, you'll put it all together by tracking organizational problems in the code and finding out how to fix them. Come join the hunt for better code!

    Even if you don't have change management in your job description, your job involves change. Change is a given as modern organizations respond to market and technology advances, make improvements, and evolve practices to meet new challenges. This is not a simple process on any level. Often, there is no indisputable right answer, and responding requires trial and error, learning and unlearning. Whatever you choose to do, it will interact with existing policies and structures in unpredictable ways. And there is, quite simply, a natural human resistance to being told to change.Rather than creating more rigorous preconceived plans or imposing change by decree, agile software developer turned organizational change expert Esther Derby offers change by attraction, an approach that is adaptive and responsive and engages people in learning, evolving, and owning the new way. She presents a set of seven heuristics--guides to problem-solving--that empower people to achieve outcomes within broad constraints using their personal ingenuity and creativity.When you work by attraction, you give space and support for people to feel the loss that comes with change and help them see what is valuable about the future you propose. Resistance fades because people feel there is nothing to push against--only something they want to move toward. Derby's approach clears the fog to provide a new way forward that honors people and creates safety for change.

    It has sold 30,000 copies in each edition and will continue to reach a huge academic audience.In this renowned book, Everett M. Rogers, professor and chair of the Department of Communication & Journalism at the University of New Mexico, explains how new ideas spread via communication channels over time. Such innovations are initially perceived as uncertain and even risky. To overcome this uncertainty, most people seek out others like themselves who have already adopted the new idea. Thus the diffusion process consists of a few individuals who first adopt an innovation, then spread the word among their circle of acquaintances--a process which typically takes months or years. But there are exceptions: use of the Internet in the 1990s, for example, may have spread more rapidly than any other innovation in the history of humankind. Furthermore, the Internet is changing the very nature of diffusion by decreasing the importance of physical distance between people. The fifth edition addresses the spread of the Internet, and how it has transformed the way human beings communicate and adopt new ideas.

    We'll use the world's most popular functional programming language: JavaScript. Some may feel this is a poor choice as it's against the grain of the current culture which, at the moment, feels predominately imperative. However, I believe it is the best way to learn FP for several reasons:You likely use it every day at work.This makes it possible to practice and apply your acquired knowledge each day on real world programs rather than pet projects on nights and weekends in an esoteric FP language.We don't have to learn everything up front to start writing programs.In a pure functional language, you cannot log a variable or read a DOM node without using monads. Here we can cheat a little as we learn to purify our codebase. It's also easier to get started in this language since it's mixed paradigm and you can fall back on your current practices while there are gaps in your knowledge.The language is fully capable of writing top notch functional code.We have all the features we need to mimic a language like Scala or Haskell with the help of a tiny library or two. Object-oriented programming currently dominates the industry, but it's clearly awkward in JavaScript. It's akin to camping off of a highway or tap dancing in galoshes. We have to bind all over the place lest this change out from under us, we don't have classes[^Yet], we have various work arounds for the quirky behavior when the new keyword is forgotten, private members are only available via closures. To a lot of us, FP feels more natural anyways.That said, typed functional languages will, without a doubt, be the best place to code in the style presented by this book. JavaScript will be our means of learning a paradigm, where you apply it is up to you. Luckily, the interfaces are mathematical and, as such, ubiquitous. You'll find yourself at home with swiftz, scalaz, haskell, purescript, and other mathematically inclined environments.

    L. Taylor examines multiplayer gaming life as it is lived on the borders, in the gaps--as players slip in and out of complex social networks that cross online and offline space. Taylor questions the common assumption that playing computer games is an isolating and alienating activity indulged in by solitary teenage boys. Massively multiplayer online games (MMOGs), in which thousands of players participate in a virtual game world in real time, are in fact actively designed for sociability. Games like the popular Everquest, she argues, are fundamentally social spaces.Taylor's detailed look at Everquest offers a snapshot of multiplayer culture. Drawing on her own experience as an Everquest player (as a female Gnome Necromancer)--including her attendance at an Everquest Fan Faire, with its blurring of online--and offline life--and extensive research, Taylor not only shows us something about games but raises broader cultural issues. She considers "power gamers," who play in ways that seem closer to work, and examines our underlying notions of what constitutes play--and why play sometimes feels like work and may even be painful, repetitive, and boring. She looks at the women who play Everquest and finds they don't fit the narrow stereotype of women gamers, which may cast into doubt our standardized and preconceived ideas of femininity. And she explores the questions of who owns game space--what happens when emergent player culture confronts the major corporation behind the game.

    The rules? No marketing budget, no PR stunts, and it must be sustainably successful. No short-term fads.This is not a game of chance. It is a game of skill and strategy.And it begins with a single question: given competing products of equal pricing, promotion, and perceived quality, why does one outsell the others?The answer doesn’t live in the sustainably successful products or services. The answer lives in those who use them.Our goal is to craft a strategy for creating successful users. And that strategy is full of surprising, counter-intuitive, and astonishingly simple techniques that don’t depend on a massive marketing or development budget. Techniques typically overlooked by even the most well-funded, well-staffed product teams.Every role is a key player in this game. Product development, engineering, marketing, user experience, support—everyone on the team. Even if that team is a start-up of one. Armed with a surprisingly overlooked science and a unique POV, we can can reduce the role of luck. We can build sustainably successful products and services that rely not on unethical persuasive marketing tricks but on helping our users have deeper, richer experiences. Not just in the moments while they’re using our product but, more importantly, in the moments when they aren’t.
