Dr. Stroustrup's Fourth Edition just released...

...and sold out! "I got my copy (the very first copy!) on Friday [May 10, 2013]. At 9am Monday, it became available on the publisher's site, InformIT, and at 10am it had sold out. Now, they have re-stocked, but this is all very scary for an author. I have worked hard on this for about four years (not counting the 13 years it took getting the C++11 standard out)," said Dr. Bjarne Stroustrup, designer and originator of C++.

What makes the fourth edition of "The C++ Programming Language" distinctive and appreciated is its inclusion of the new C++11 standard. C++11 "allows programmers to express ideas more clearly, simply, and directly, and to write faster, more efficient code," writes Dr. Stroustrup.

The C++ Programming Language, Fourth Edition has been extensively rewritten to introduce the C++11 language, the C++11 standard library, and the programming techniques they support. This includes "support for concurrency; regular expressions, resource management pointers, random numbers, and improved containers; general and uniform initialization, simplified for statements, move semantics, and Unicode support; Lambdas, general constant expressions, control over class defaults, variadic templates, template aliases, and user-defined literals; and compatibility issues."

Dr. Bjarne Stroustrup is a University Distinguished Professor and the holder of the College of Engineering Chair in Computer Science at Texas A&M University. The recipient of numerous honors, Dr. Stroustrup is a member of the National Academy of Engineering, an IEEE Fellow, and an ACM Fellow. His research interests include distributed systems, simulation, design, programming techniques, software development tools, and programming languages. He remains actively involved in the ANSI/ISO standardization of C++. Dr. Stroustrup holds an advanced degree from the University of Aarhus in his native Denmark and a Ph.D. in Computer Science from Cambridge University, England.

Open and Efficient Type Switch for C++

by Yuriy Solodkyy, Gabriel Dos Reis, and Bjarne Stroustrup

Selecting operations based on the run-time type of an object is key to many object-oriented and functional programming techniques. We present a technique for implementing open and efficient type switching on hierarchical extensible data types. The technique is general and copes well with C++ multiple inheritance.

To simplify experimentation and gain realistic performance using production-quality compilers and tool chains, we implement a type switch construct as an ISO C++11 library, called Mach7. This library-only implementation provides concise notation and outperforms the visitor design pattern, commonly used for case analysis on types in object-oriented programming. For closed sets of types, its performance roughly equals equivalent code in functional languages, such as OCaml and Haskell. The type-switching code is easier to use and is more expressive than hand-coded visitors are. The library is non-intrusive and circumvents most of the extensibility restrictions typical of the visitor design pattern. It was motivated by applications involving large, typed, abstract syntax trees.

HotDrink: A Library for Web User Interfaces

by John Freeman, Jaakko Järvi, and Gabriel Foust

HotDrink is a JavaScript library for constructing forms, dialogs, and other common user interfaces for Web applications. With HotDrink, instead of writing event handlers, developers declare a "view-model" in JavaScript and a set of "bindings" between the view-model and the HTML elements comprising the view. These specifications tend to be small, but they are enough for HotDrink to provide a fully operational GUI with multi-way dataflows, enabling/disabling of values, activation/deactivation of commands, and data validation. HotDrink implements these rich behaviors, expected of high-quality user interfaces, as generic reusable algorithms. This paper/tool demonstration introduces developers to the HotDrink library by stepping through the construction of an example web application GUI.

The library is a concrete realization of our prior work on the "property models" approach to declarative GUI programming. To encourage adoption among developers, we have packaged the technology following established web programming conventions.

An Automatic Parallelization Framework for Algebraic Computation Systems

A paper "An Automatic Parallelization Framework for Algebraic Computation Systems" by Yue Li and Gabriel Dos Reis was accepted by ISSAC 2011

Abstract:
This paper proposes an automatic parallelization framework for an existing computer algebra system. The framework performs a semantics-based static analysis to extract reductions in library components. Reductions using associative binary operators are automatically transformed to their parallel versions. Our implementation is evaluated using algebraic library functions and a self-implemented application. Experimental results show that up to 5 times speed-up for the application is obtained. It is feasible to adapt the core of this framework to other algebraic computation systems and programming languages. The adaptation requires a type system which is able to provide semantics algebraic information from users.

Extending Type Systems in a Library

Type-safe XML processing in C++
by Yuriy Solodkyy and Jaakko Järvi

Abstract

Type systems built directly into the compiler or interpreter of a programming language cannot be easily extended to keep track of run-time invariants of new abstractions. Yet, programming with domain-specific abstractions could benefit from additional static checking. This paper presents library techniques for extending the type system of C++ to support domain-specific abstractions. The main contribution is a programmable “subtype” relation. As a demonstration of the techniques, we implement a type system for defining type qualifiers in C++, as well as a type system for the XML processing language, capable of, e.g., statically guaranteeing that a program only produces valid XML documents according to a given XML schema.

Research highlights

• Metaprogramming capabilities of C++ enable domain-specific type system extensions.
  
• A template library for building new type system extensions.
  
• Type system extensions for type qualifiers.
  
• Type system extensions for regular expression types for typing XML.

Literature Search for Computer Science

by Todd Veldhuizen

Abstract

Why read the literature?

• Because sometimes "a year of hard work can save a week of reading".
  
• Increase the likelihood that someone will care about your research:
  • Not duplicate an already known result.
    
  • Identify communities of people who will appreciate what you are doing.
    
• Be able to give a convincing treatment of your research problem:
  • Using standard terminology and notations;
    
  • Comparing your contribution to related work;
    
  • Avoiding obvious ‘newbie ’ mistakes
    
  • Not getting crushed by some crusty professor who claims to have published your result twenty years ago.
