The Complete Guide to Avoiding and Fixing Common Rails 3 Code and Design Problems

As developers worldwide have adopted the powerful Ruby on Rails web framework, many have fallen victim to common mistakes that reduce code quality, performance, reliability, stability, scalability, and maintainability. Rails™ AntiPatterns identifies these widespread Rails code and design problems, explains why they’re bad and why they happen—and shows exactly what to do instead.

 

The book is organized into concise, modular chapters—each outlines a single common AntiPattern and offers detailed, cookbook-style code solutions that were previously difficult or impossible to find. Leading Rails developers Chad Pytel and Tammer Saleh also offer specific guidance for refactoring existing bad code or design to reflect sound object-oriented principles and established Rails best practices. With their help, developers, architects, and testers can dramatically improve new and existing applications, avoid future problems, and establish superior Rails coding standards throughout their organizations.

 

This book will help you understand, avoid, and solve problems with

  •  Model layer code, from general object-oriented programming violations to complex SQL and excessive redundancy
  • Domain modeling, including schema and database issues such as normalization and serialization
  • View layer tools and conventions
  • Controller-layer code, including RESTful code
  • Service-related APIs, including timeouts, exceptions, backgrounding, and response codes
  • Third-party code, including plug-ins and gems
  • Testing, from test suites to test-driven development processes
  • Scaling and deployment
  • Database issues, including migrations and validations
  • System design for “graceful degradation” in the real world

Algorithms for Fuzzy Clustering: Methods in c-Means Clustering with Applications (Studies in Fuzziness and Soft Computing)
The main subject of this book is the fuzzy c-means proposed by Dunn and Bezdek and their variations including recent studies. A main reason why we concentrate on fuzzy c-means is that most methodology and application studies in fuzzy clustering use fuzzy c-means, and hence fuzzy c-means should be considered to be...
