Praise for layout styles in Ruby

"Design styles in Ruby files shrewdpermanent how you can unravel many difficulties that Ruby builders typically stumble upon. Russ Olsen has performed a very good task of choosing vintage styles and augmenting those with more moderen styles that experience unique relevance for Ruby. He in actual fact explains every one suggestion, creating a wealth of expertise on hand to Ruby builders for his or her personal day-by-day paintings. "

—Steve Metsker, coping with advisor with Dominion electronic, Inc.

"This e-book presents a good demonstration of the major 'Gang of Four' layout styles with out resorting to overly technical causes. Written in an actual, but nearly casual sort, this publication covers sufficient flooring that even these with out earlier publicity to layout styles will quickly think convinced making use of them utilizing Ruby. Olsen has performed a superb task to make a publication a couple of classically 'dry' topic into such an enticing or even sometimes funny learn. "

—Peter Cooper

"This booklet renewed my curiosity in figuring out styles after a decade of excellent intentions. Russ picked the main beneficial styles for Ruby and brought them in a simple and logical demeanour, going past the GoF's styles. This publication has more desirable my use of Ruby, and inspired me to blow off the dirt protecting the GoF booklet. "

—Mike Stok

"Design styles in Ruby is a smart means for programmers from statically typed objectoriented languages to benefit how layout styles seem in a extra dynamic, versatile language like Ruby. "

—Rob Sanheim, Ruby Ninja, Relevance

Most layout trend books are in response to C++ and Java. yet Ruby is different—and the language's designated characteristics make layout styles more straightforward to enforce and use. during this booklet, Russ Olsen demonstrates tips on how to mix Ruby's energy and magnificence with styles, and write extra refined, powerful software program with a ways fewer traces of code.

After reviewing the background, options, and targets of layout styles, Olsen bargains a brief journey of the Ruby language—enough to permit any skilled software program developer to instantly make the most of styles with Ruby. The ebook specially calls consciousness to Ruby good points that simplify using styles, together with dynamic typing, code closures, and "mixins" for less complicated code reuse.

Fourteen of the vintage "Gang of Four" styles are thought of from the Ruby perspective, explaining what difficulties each one development solves, discussing even if conventional implementations make experience within the Ruby setting, and introducing Ruby-specific advancements. You'll realize possibilities to enforce styles in exactly one or strains of code, rather than the eternally repeated boilerplate that traditional languages usually require.

Design styles in Ruby additionally identifies leading edge new styles that experience emerged from the Ruby neighborhood. those comprise how one can create customized gadgets with metaprogramming, in addition to the formidable Rails-based "Convention Over Configuration" development, designed to assist combine complete purposes and frameworks.

Write Great Code, Volume 1: Understanding the Machine

If you've requested an individual the key to writing effective, well-written software program, the reply that you've most likely gotten is "learn meeting language programming. " by way of studying meeting language programming, you find out how the laptop fairly operates and that wisdom can help you write larger high-level language code. a grimy little mystery meeting language programmers hardly admit to, notwithstanding, is that what you really want to benefit is computing device association, now not meeting language programming. Write nice Code Vol I, the 1st in a sequence from meeting language professional Randall Hyde, dives correct into computer association with no the additional overhead of studying meeting language programming even as. and because Write nice Code Vol I concentrates at the computing device association, no longer meeting language, the reader will study in higher intensity these topics which are language-independent and of shock to a excessive point language programmer. Write nice Code Vol i'll aid programmers make wiser offerings with appreciate to programming statements and knowledge varieties while writing software program, irrespective of which language they use.

If you come from a * Based on personal experience and confirmed by threads on the Erlang-questions mailing list, this is more common than you might first believe. 18 | Chapter 2: Basic Erlang C or a Java background, you might have noticed that there is no need to convert integers to floats before performing floating-point division. Atoms Atoms are constant literals that stand for themselves. Atoms serve much the same purpose as values in enumeration types in other languages; for the beginner, it sometimes helps to think of them as a huge enumeration type.

Symmetric multiprocessing (SMP) support in Erlang was first developed experimentally in the late 1990s, and is now an integral part of the standard release. The ethos of the Erlang/OTP development team at Ericsson is to make SMP work, measure its performance, find the bottlenecks, and optimize. Since releasing the first SMP-enabled version of Erlang, this has been their approach. Over recent releases, the virtual machine model has evolved from a single monolithic run queue—possibly with processes running on different processors—to a run queue for each processor, ensuring that the run queue is no longer a bottleneck for the system, as illustrated in Figure 1-3.

We quickly changed our minds when we realized the research project was being done in cooperation with Motorola Labs, one of Ericsson’s competitors. Although Heriot-Watt might have taken Ericsson’s word that Erlang was suitable for programming telecom applications, Motorola wasn’t having any of it.
