Book Synopsis Should Your Specification Language be Typed? by : Leslie Lamport
Download or read book Should Your Specification Language be Typed? written by Leslie Lamport and published by . This book was released on 1997 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Most specification languages have a type system. The languages used in some popular textbooks have half-baked type systems that are described informally and never spelled out in detail. Such type systems tend to have unexpected consequences, if not outright inconsistencies. Set theory can serve as the basis for a specification language without types. This possibility, which has been widely overlooked, offers many advantages. Set theory is simpler and more flexible than most typed formalisms. Polymorphism, overloading, and subtyping can make a type system more powerful, but at the cost of increased complexity, and such refinements can never attain the flexibility of having no types at all. Typed formalisms have advantages too, stemming from the power of mechanical type checking. While types serve little purpose in hand proofs, they do help with mechanized proofs. In the absence of verification, type checking can catch errors in specifications. It may be possible to have the best of both worlds by adding typing annotations to an untyped specification language. We consider only specification languages, not programming languages."

Book Synopsis Can static type systems speed up programming? An experimental evaluation of static and dynamic type systems by : Sebastian Kleinschmager
Download or read book Can static type systems speed up programming? An experimental evaluation of static and dynamic type systems written by Sebastian Kleinschmager and published by Anchor Academic Publishing (aap_verlag). This book was released on 2013-06-01 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Programming languages that use the object-oriented approach have been around for quite a while now. Most of them use either a static or a dynamic type system. However, both types are very common in the industry. But, in spite of their common use in science and practice, only very few scientific studies have tried to evaluate the two type systems' usefulness in certain scenarios. There are arguments for both systems. For example, static type systems are said to aid the programmer in the prevention of type errors, and further, they provide documentation help for, there is an explicit need to annotate variables and methods with their respective types. This book describes a controlled experiment that was conducted to shed some light into the presented matter. Which of the type systems can live up to its promises? Is one of these better suited for a particular task? And which type system is the most supportive in a problem solving? The main hypothesis claims that a static type system is faster in a problem solving in use of an undocumented API. Thus, in the study, the participants need to solve different programming tasks in an undocumented API environment with the help of the static type system (Java), and the dynamic type system (Groovy). The author starts with a short introduction to the topic, the experimentation, and the motivation. Then, he describes a list of related works, and proceeds to the description of the experiment, its evaluation, and finally, the discussion of the results. This book should prove interesting reading for anyone who is interested in the mechanics that drive programmer productivity and performance that depend on the kind of technology used, as well as for anyone who might be interested in empirical research in software engineering, in general.

Book Synopsis Crafting Interpreters by : Robert Nystrom
Download or read book Crafting Interpreters written by Robert Nystrom and published by Genever Benning. This book was released on 2021-07-27 with total page 1021 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite using them every day, most software engineers know little about how programming languages are designed and implemented. For many, their only experience with that corner of computer science was a terrifying "compilers" class that they suffered through in undergrad and tried to blot from their memory as soon as they had scribbled their last NFA to DFA conversion on the final exam. That fearsome reputation belies a field that is rich with useful techniques and not so difficult as some of its practitioners might have you believe. A better understanding of how programming languages are built will make you a stronger software engineer and teach you concepts and data structures you'll use the rest of your coding days. You might even have fun. This book teaches you everything you need to know to implement a full-featured, efficient scripting language. You'll learn both high-level concepts around parsing and semantics and gritty details like bytecode representation and garbage collection. Your brain will light up with new ideas, and your hands will get dirty and calloused. Starting from main(), you will build a language that features rich syntax, dynamic typing, garbage collection, lexical scope, first-class functions, closures, classes, and inheritance. All packed into a few thousand lines of clean, fast code that you thoroughly understand because you wrote each one yourself.
Book Synopsis Larch: Languages and Tools for Formal Specification by : John V. Guttag
Download or read book Larch: Languages and Tools for Formal Specification written by John V. Guttag and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building software often seems harder than it ought to be. It takes longer than expected, the software's functionality and performance are not as wonderful as hoped, and the software is not particularly malleable or easy to maintain. It does not have to be that way. This book is about programming, and the role that formal specifications can play in making programming easier and programs better. The intended audience is practicing programmers and students in undergraduate or basic graduate courses in software engineering or formal methods. To make the book accessible to such an audience, we have not presumed that the reader has formal training in mathematics or computer science. We have, however, presumed some programming experience. The roles of fonnal specifications Designing software is largely a matter of combining, inventing, and planning the implementation of abstractions. The goal of design is to describe a set of modules that interact with one another in simple, well defined ways. If this is achieved, people will be able to work independently on different modules, and yet the modules will fit together to accomplish the larger purpose. In addition, during program maintenance it will be possible to modify a module without affecting many others. Abstractions are intangible. But they must somehow be captured and communicated. That is what specifications are for. Specification gives us a way to say what an abstraction is, independent of any of its implementations.
Book Synopsis The Language Demands of School by : Alison L. Bailey
Download or read book The Language Demands of School written by Alison L. Bailey and published by Yale University Press. This book was released on 2007-01-01 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Language Demands of School is an edited volume describing an extensive empirical base for academic English testing, instruction and professional development. The chapters comprise empirical research by Bailey and colleagues at the National Center for Research on Evaluation, Standards, Student Testing (CRESST) at UCLA, and invited contributions by practitioners in the fields of language policy, testing and instruction. The central focus of the chapters is the research conducted by CRESST over the last two years in an attempt to document the academic English language demands placed on school-age learners of English. The three additional chapters give the perspectives of a policy-maker at the state level, test developers, and practitioners. The Language Demands of School fills a gap in the current literature by addressing the kind(s) of English required of K-12 English Learner students from an evidence-based perspective. This is timely given the broader context of the No Child Left Behind Act of 2001, which has prompted school systems to identify English language proficiency tests to meet the federal mandate. One of the problems that has surfaced in the search for English language tests for K-12 English Learner students is the inadequacy of existing research on the development of the academic English language skills that all students—both English Learner and native English-speaking—need to be successful in the school setting. The Language Demands of School is devoted to exploring this topic and to presenting research that illuminates both the questions and the answers.
Book Synopsis Static Analysis by : Agostino Cortesi
Download or read book Static Analysis written by Agostino Cortesi and published by Springer. This book was released on 2003-07-31 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Static analysis is increasingly recognized as a fundamental reasearch area aimed at studying and developing tools for high performance implementations and v- i cation systems for all programming language paradigms. The last two decades have witnessed substantial developments in this eld, ranging from theoretical frameworks to design, implementation, and application of analyzers in optim- ing compilers. Since 1994, SAS has been the annual conference and forum for researchers in all aspects of static analysis. This volume contains the proceedings of the 6th International Symposium on Static Analysis (SAS’99) which was held in Venice, Italy, on 22{24 September 1999. The previous SAS conferences were held in Namur (Belgium), Glasgow (UK), Aachen (Germany), Paris (France), and Pisa (Italy). The program committee selected 18 papers out of 42 submissions on the basis of at least three reviews. The resulting volume o ers to the reader a complete landscape of the research in this area. The papers contribute to the following topics: foundations of static analysis, abstract domain design, and applications of static analysis to di erent programming paradigms (concurrent, synchronous, imperative, object oriented, logical, and functional). In particular, several papers use static analysis for obtaining state space reduction in concurrent systems. New application elds are also addressed, such as the problems of security and secrecy.
Book Synopsis The Object-Z Specification Language by : Graeme Smith
Download or read book The Object-Z Specification Language written by Graeme Smith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Object-Z is an object-oriented extension of the formal specification language Z. It adds to Z notions of classes and objects, and inheritance and polymorphism. By extending Z's semantic basis, it enables the specification of systems as collections of independent objects in which self and mutual referencing are possible. The Object-Z Specification Language presents a comprehensive description of Object-Z including discussions of semantic issues, definitions of all language constructs, type rules and other rules of usage, specification guidelines, and a full concrete syntax. It will enable you to confidently construct Object-Z specifications and is intended as a reference manual to keep by your side as you use and learn to use Object-Z. The Object-Z Specification Language is suitable as a textbook or as a secondary text for a graduate-level course, and as a reference for researchers and practitioners in industry.
