Book excerpt: When realizing a programming language as VM, implementing behavior as part of the VM, as primitive, usually results in reduced execution times. But supporting and developing primitive functions requires more effort than maintaining and using code in the hosted language since debugging is harder, and the turn-around times for VM parts are higher. Furthermore, source artifacts of primitive functions are seldom reused in new implementations of the same language. And if they are reused, the existing API usually is emulated, reducing the performance gains. Because of recent results in tracing dynamic compilation, the trade-off between performance and ease of implementation, reuse, and changeability might now be decided adversely. In this work, we investigate the trade-offs when creating primitives, and in particular how large a difference remains between primitive and hosted function run times in VMs with tracing just-in-time compiler. To that end, we implemented the algorithmic primitive BitBlt three times for RSqueak/VM. RSqueak/VM is a Smalltalk VM utilizing the PyPy RPython toolchain. We compare primitive implementations in C, RPython, and Smalltalk, showing that due to the tracing just-in-time compiler, the performance gap has lessened by one magnitude to one magnitude.

Available in PDF, EPUB and Kindle. Book excerpt: You don't have to accept slow Ruby or Rails performance. In this comprehensive guide to Ruby optimization, you'll learn how to write faster Ruby code--but that's just the beginning. See exactly what makes Ruby and Rails code slow, and how to fix it. Alex Dymo will guide you through perils of memory and CPU optimization, profiling, measuring, performance testing, garbage collection, and tuning. You'll find that all those "hard" things aren't so difficult after all, and your code will run orders of magnitude faster. This is the first book ever that consolidates all the Ruby performance optimization advice in one place. It's your comprehensive guide to memory optimization, CPU optimization, garbage collector tuning, profiling, measurements, performance testing, and more. You'll go from performance rookie to expert. First, you'll learn the best practices for writing Ruby code that's easy not only on the CPU, but also on memory, and that doesn't trigger the dreaded garbage collector. You'll find out that garbage collection accounts for 80% of slowdowns, and often takes more than 50% of your program's execution time. And you'll discover the bottlenecks in Rails code and learn how selective attribute loading and preloading can mitigate the performance costs of ActiveRecord. As you advance to Ruby performance expert, you'll learn how profile your code, how to make sense out of profiler reports, and how to make optimization decisions based on them. You'll make sure slow code doesn't creep back into your Ruby application by writing performance tests, and you'll learn the right way to benchmark Ruby. And finally, you'll dive into the Ruby interpreter internals to really understand why garbage collection makes Ruby so slow, and how you can tune it up. What You Need: Some version of Ruby. The advice from this book applies to all modern Ruby versions from 1.9 to 2.2. 80% of the material will also be useful for legacy Ruby 1.8 users, and there is 1.8-specific advice as well.

From their beginning, the ECOOP conferences have been very successful as a forum of high scientific quality where the newest devel- opments connected to object-oriented programming and related areas could be presented and discussed. Over the last few years object-oriented technology has gained widespread use and considerable popularity. In parallel with this, the field has matured scientifically, but there is still a lot of room for new ideas and for hot debates over fundamental issues, as these proceedings show. The 22 papers in this volume were selected by the programme committee from 129 submissions. Important issues discussed in the contributions are language design, specification, databases, concurrency types and software development.

Book excerpt: Program generation holds the promise of helping to bridge the gap between application-level problem solutions and efficient implementations at the level of today's source programs as written in C or Java. Thus, program generation can substantially contribute to reducing production cost and time-to-market in future software production, while improving the quality and stability of the product. This book is about domain-specific program generation; it is the outcome of a Dagstuhl seminar on the topic held in March 2003. After an introductory preface by the volume editors, the 18 carefully reviewed revised full papers presented are organized into topical sections on - surveys of domain-specific programming technologies - domain-specific programming languages - tool support for program generation - domain-specific techniques for program optimization

Book excerpt: Design thinking as a user-centric innovation method has become more and more widespread during the past years. An increasing number of people and institutions have experienced its innovative power. While at the same time the demand has grown for a deep, evidence-based understanding of the way design thinking functions. This challenge is addressed by the Design Thinking Research Program between Stanford University, Palo Alto, USA and Hasso Plattner Institute, Potsdam, Germany. Summarizing the outcomes of the 5th program year, this book imparts the scientific findings gained by the researchers through their investigations, experiments and studies. The method of design thinking works when applied with diligence and insight. With this book and the underlying research projects, we aim to understand the innovation process of design thinking and the people behind it. The contributions ultimately center on the issue of building innovators. The focus of the investigation is on what people are doing and thinking when engaged in creative design innovation and how their innovation work can be supported. Therefore, within three topic areas, various frameworks, methodologies, mind sets, systems and tools are explored and further developed. The book begins with an assessment of crucial factors for innovators such as empathy and creativity, the second part addresses the improvement of team collaboration and finally we turn to specific tools and approaches which ensure information transfer during the design process. All in all, the contributions shed light and show deeper insights how to support the work of design teams in order to systematically and successfully develop innovations and design progressive solutions for tomorrow.

Available in PDF, EPUB and Kindle. Book excerpt: Program analysis utilizes static techniques for computing reliable information about the dynamic behavior of programs. Applications include compilers (for code improvement), software validation (for detecting errors) and transformations between data representation (for solving problems such as Y2K). This book is unique in providing an overview of the four major approaches to program analysis: data flow analysis, constraint-based analysis, abstract interpretation, and type and effect systems. The presentation illustrates the extensive similarities between the approaches, helping readers to choose the best one to utilize.
