The study of type systems--and of programming languages from a type-theoretic perspective--has important applications in software engineering, language design, high-performance compilers, and security.This text provides a comprehensive introduction both to type systems in computer science and to the basic theory of programming languages. The approach is pragmatic and operational; each new concept is motivated by programming examples and the more theoretical sections are driven by the needs of implementations. Each chapter is accompanied by numerous exercises and solutions, as well as a running implementation, available via the Web. Dependencies between chapters are explicitly identified, allowing readers to choose a variety of paths through the material.The core topics include the untyped lambda-calculus, simple type systems, type reconstruction, universal and existential polymorphism, subtyping, bounded quantification, recursive types, kinds, and type operators. Extended case studies develop a variety of approaches to modeling the features of object-oriented languages.

    She’s been looking for fireworks in her love life ever since she broke up with her predictable ex-boyfriend Giles, but she has no thoughts of kindling the spark she’s looking for here. If she can’t find love in a big city like London – with all its internet dating, singles nights, and socials – how can she ever hope to meet the man of her dreams in the tiny village of St Pontian? But there are two prospects when she gets there: Martin who can always be depended on for a kind word of advice. And Toby, who is distant, but who sets her heart ablaze. When it comes to love, should Laney trust the logic of her head or the racing of her heart?

    Polya, How to Solve It will show anyone in any field how to think straight. In lucid and appealing prose, Polya reveals how the mathematical method of demonstrating a proof or finding an unknown can be of help in attacking any problem that can be reasoned out--from building a bridge to winning a game of anagrams. Generations of readers have relished Polya's deft--indeed, brilliant--instructions on stripping away irrelevancies and going straight to the heart of the problem.

    Cooper details many of these meta functions to explain his central thesis: programmers need to seriously re-evaluate the many user-hostile concepts deeply embedded within the software development process. Rather than provide users with a straightforward set of options, programmers often pile on the bells and whistles and ignore or de-prioritise lingering bugs. For the average user, increased functionality is a great burden, adding to the recurrent chorus that plays: "computers are hard, mysterious, unwieldy things." (An average user, Cooper asserts, who doesn't think that way or who has memorised all the esoteric commands and now lords it over others, has simply been desensitised by too many years of badly designed software.) Cooper's writing style is often overblown, with a pantheon of cutesy terminology (i.e. "dancing bearware") and insider back-patting. (When presenting software to Bill Gates, he reports that Gates replied: "How did you do that?" to which he writes: "I love stumping Bill!") More seriously, he is also unable to see beyond software development's importance--a sin he accuses programmers of throughout the book. Even with that in mind, the central questions Cooper asks are too important to ignore: Are we making users happier? Are we improving the process by which they get work done? Are we making their work hours more effective? Cooper looks to programmers, business managers and what he calls "interaction designers" to question current assumptions and mindsets. Plainly, he asserts that the goal of computer usage should be "not to make anyone feel stupid." Our distance from that goal reinforces the need to rethink entrenched priorities in software planning. -- Jennifer Buckendorff, Amazon.com

    Small-scale, self-contained worm bins can be kept indoors, in a basement or even under the kitchen sink in an apartment — making vermicomposting a great option for city dwellers and anyone who doesn’t want or can’t have an outdoor compost pile. The fully revised 35th anniversary edition features the original’s same friendly tone, with up-to-date information on the entire process, from building or purchasing a bin (readily available at garden supply stores), maintaining the worms, and harvesting the finished compost.

    But only when their rage explodes and unspeakable crimes are committed do we realise we hold them in our midst. Some are unpredictable psychopaths, others achieve notoriety after a moment of madness when a single out-of-character act changes their lives forever. One thing is for certain, homicide comes in many guises - the only thing most have in common is a corpse. In The Law Killers, journalist Alexander McGregor examines some of the people and deeds, which have terrorised Dundonian communities. Having reported on many of them first-hand, he has unique insight into the cases and they are as chilling as they are compelling. The father who wanted to go one better than his double-killer son...and did. The groom who promised to love, honour and cherish both his brides...before he strangled them. The thirteen-year-old who was almost as much a victim as the child she killed. The trail of slaughter that started with a break-in and ended hundreds of miles away after an escaped convict killed again...and again and again.The unsolved murder of the wealthy spinster who led a secret life. The trail of dead women in the life of a social worker who thought he could outwit the police...and nearly did

    Emphasizes possible, realistic and "best practice" approaches for managers, technical leads and self-managed teams. The author emphasizes efficient development concepts with an examination of rapid development strategies and a study of classic mistakes, within the context of software-development fundamentals and risk management. Dissects the core issues of rapid development, lifecycle planning, estimation and scheduling. Contains very good and practical discussions of customer-oriented development, motivation and teamwork. Explains such fundamental requirements as team structure, feature-set control (the dreaded feature creep in every project), availability and use of productivity tools and project recovery options. Relevant case studies are analyzed and discussed within the context of specific software development problems. Over 200 pages in this publication are devoted to a summary of best practices, everything from the daily build and smoke test, through prototyping, model selection, measurement, reuse, and the top-10 risks list. This publication is definitely recommended and will become a classic in the field, just as the author's prior publication, "Code Complete" already is.

    Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. Quanta, under editor-in-chief Thomas Lin, is the only popular publication that offers in-depth coverage of today's challenging, speculative, cutting-edge science. It communicates science by taking it seriously, wrestling with difficult concepts and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.In the title story, Alice and Bob--beloved characters of various thought experiments in physics--grapple with gravitational forces, possible spaghettification, and a massive wall of fire as Alice jumps into a black hole. Another story considers whether the universe is impossible, in light of experimental results at the Large Hadron Collider. We learn about quantum reality and the mystery of quantum entanglement; explore the source of time's arrow; and witness a eureka moment when a quantum physicist exclaims: "Finally, we can understand why a cup of coffee equilibrates in a room." We reflect on humans' enormous skulls and the Brain Boom; consider the evolutionary benefits of loneliness; peel back the layers of the newest artificial-intelligence algorithms; follow the "battle for the heart and soul of physics"; and mourn the disappearance of the "diphoton bump," revealed to be a statistical fluctuation rather than a revolutionary new particle. These stories from Quanta give us a front-row seat to scientific discovery.ContributorsPhilip Ball, K. C.

    The authors are well-known for their clear presentation that makes the material accessible to a a broad audience and requires no special previous mathematical experience. KEY TOPICS: In this new edition, the authors incorporate a somewhat more informal, friendly writing style to present both classical and contemporary theories of computation. Algorithms, complexity analysis, and algorithmic ideas are introduced informally in Chapter 1, and are pursued throughout the book. Each section is followed by problems.

    In Making the World Work Better: The Ideas That Shaped a Century and a Company, journalists Kevin Maney, Steve Hamm and Jeffrey M. O’Brien tell a story of progress that illuminates, and transcends, the rich history of a single enterprise.Through extensive research, they explore IBM’s impact on technology, on the evolving role of the modern corporation and on the way our world literally works. Most intriguingly, they uncover a set of compelling ideas whose greatest impact may lie not in the previous century, but in the next one—ideas with the power to shape a surprising future, and to change the way we think.

    In his darkest moments, when those dreams were dashed, he dug deep with the help of an unlikely friend—five-year-old Maddux Maple, a local hometown fan with leukemia. They made a pact: Cody would be in the UFC and win the championship, and Maddux would beat cancer. Read their moving story in Cody’s new book, The Pact, and go behind the scenes into Cody’s training and how he made his dreams come true. Cody Garbrandt grew up in a rough town in the Central Appalachian region of Ohio, surrounded by a longstanding culture of fighting—and drugs. Raised in this environment by a single mom (his dad left him at the young age of three to reside in the Ohio State Penitentiary), Cody grew up fighting, and he grew up wild. His future seemed predestined to end in the coal mines, or in prison.Thankfully, Cody had visions of something more. His American Dream? Mixed Martial Arts. But a path to success wasn’t clear. He spent as much time fighting in the streets as he did in the gym—one bad decision away from losing everything. Then, at age 20, Cody’s brother introduced him to five-year old Maddux Maple. Maddux was deathly ill with leukemia, his survival by no means assured. A unique friendship developed as they made a promise to each other: Maddux would beat cancer, and Cody would make it to the UFC and become world champion.Through five long years of pain and hardship, they both persevered; Cody, through the agony and sacrifices of fighting his way to the top, and Maddux through the horrors of chemotherapy. They loved and supported each other. They served as each other’s inspiration. And in December 2016, they made good on their pact: Cody won his UFC Championship belt, which he promptly presented to Maddux—the boy who had beaten cancer into remission.
