Software practitioners are rapidly discovering the immense value of Domain-Specific Languages (DSLs) in solving problems within clearly definable problem domains. Developers are applying DSLs to improve productivity and quality in a wide range of areas, such as finance, combat simulation, macro scripting, image generation, and more. But until now, there have been few practical resources that explain how DSLs work and how to construct them for optimal use.

 

Software Language Engineering fills that need. Written by expert DSL consultant Anneke Kleppe, this is the first comprehensive guide to successful DSL design. Kleppe systematically introduces and explains every ingredient of an effective

language specification, including its description of concepts, how those concepts are denoted, and what those concepts mean in relation to the problem domain. Kleppe carefully illuminates good design strategy, showing how to maximize the flexibility of the languages you create. She also demonstrates powerful techniques for creating new DSLs that cooperate well with general-purpose languages and leverage their power.

 

Completely tool-independent, this book can serve as the primary resource for readers using Microsoft DSL tools, the Eclipse Modeling Framework, openArchitectureWare, or any other DSL toolset. It contains multiple examples, an illustrative running case study, and insights and background information drawn from Kleppe’s leading-edge work as a DSL researcher.

 

Specific topics covered include

 

• Discovering the types of problems that DSLs can solve, and when to use them
• Comparing DSLs with general-purpose languages, frameworks, APIs, and other approaches
• Understanding the roles and tools available to language users and engineers
• Creating each component of a DSL specification
• Modeling both concrete and abstract syntax
• Understanding and describing language semantics
• Defining textual and visual languages based on object-oriented metamodeling and graph transformations
• Using metamodels and associated tools to generate grammars
• Integrating object-oriented modeling with graph theory
• Building code generators for new languages
• Supporting multilanguage models and programs

 

This book provides software engineers with all the guidance they need to create DSLs that solve real problems more rapidly, and with higher-quality code.

I’ve pulled together and presented three separate articles about the famous Match Race betweenthe Champion racehorse BOSTON & the racemare FASHION that tell of the circumstances surrounding the race, the race itself & the recap of the race.

The article also depicts the chaos surrounding the event in terms of the crush of humanity trying to get to the Long Island track & near-riot the event precipitated.

When Michelle Gibson reports her father, Mick Prentice, missing at the start of McDermid’s intricate but underwhelming stand-alone psychological thriller, Det. Insp. Karen Pirie, head of the Fife police Cold Case Review Team, isn’t interested until Michelle reveals that Mick disappeared during the 1984 miners’ strike. At the time, everyone believed Mick went scabbing in Nottingham. Later, Karen is summoned to the home of wealthy Sir Broderick Maclennan Grant, whose daughter, Catriona, and baby grandson, Adam, were abducted in 1985. A botched ransom hand-off left Catriona dead and Adam nowhere to be found. New evidence linked to the kidnapping has surfaced, and now Karen has two missing people to locate. McDermid tries to pack too much story into one book, and the connection she draws between the cases feels forced. Fans of the Scottish author may be better off waiting for the next outing of McDermid’s series to feature psychologist Tony Hill (The Mermaid Singing, etc.). Author tour. (Feb.)

McDermid’s latest is a stand-alone set in Fife, Scotland. Detective Inspector Karen Pirie, newly appointed head of the Cold Case squad, has a hard time with desk work, so when a woman reports her father missing and last seen in 1984, Pirie can’t resist. But her boss, a paper pusher known as the Macaroon, wants Karen in the office, at least until Bel, an investigative journalist, turns up new evidence in a 20-year-old heiress kidnap case. As Karen and Bel investigate, friends’ and family members’ memories of the missing people are delivered as flashbacks, resulting in short chapters, multiple viewpoints, and a moderately quick pace. As Karen’s two cases seem to converge, the complex and layered plotlines come together, and McDermid does an excellent job creating tension around a cold case. Sure to be a hit with McDermid’s large fan base, it should also appeal to those who read other Scottish police mysteries, such as Stuart MacBride’s (Flesh House, 2008). Those who enjoyed the cold-case aspect may also enjoy Johan Theorin’s Echoes from the Dead (2008). –Jessica Moyer

The main goal of this book is to provide an overview of some of the most recent developments in the field of Domain Decomposition Methods. Domain decomposition relates to the construction of preconditioners for the large algebraic systems of equations which often arise in applications, by solving smaller instances of the same problem. It also relates to the construction of approximation methods built from different discretizations in different subdomains. The resulting methods are among the most successful parallel solvers for many large scale problems in computational science and engineering. The papers in this collection reflect some of the most active research areas in domain decomposition such as novel FETI, Neumann-Neumann, overlapping Schwarz and Mortar methods.
