Release Date: 2007-06-01
Genre: Computers

There may be no better way to learn how to program than by dissecting real, representative examples written in your language of choice. Ruby by Example analyzes a series of Ruby scripts, examining how the code works, explaining the concepts it illustrates, and showing how to modify it to suit your needs. Baird's examples demonstrate key features of the language (such as inheritance, encapsulation, higher-order functions, and recursion), while simultaneously solving difficult problems (such as validating XML, creating a bilingual program, and creating command-line interfaces). Each chapter builds upon the previous, and each key concept is highlighted in the margin to make it easier for you to navigate the book. You'll learn how to: –Use the interactive Ruby shell (irb) to learn key features of the language –Extend Ruby using RubyGems, the Ruby package manager –Create numerical utilities, as well as utilities that process and analyze HTML/XML –Implement purely functional and metaprogramming techniques to save time and effort –Optimize, profile, and test your code to make sure that it not only does its job, but does it well –Create web applications using Rails Ruby is the fastest growing programming language today, and for good reason: its elegant syntax and readable code make for prolific and happy programmers. But it can be difficult to understand and implement without a little help. Ruby by Example shows you how to take advantage of Ruby as you explore Ruby's fundamental concepts in action.

Vivisection

Author: Eric Weinstein
Publisher:
ISBN: 1934832251
Release Date: 2010-11-01
Genre: Poetry

"These elegant lines cut deep, not into bodies but into thoughts, thoughts about bodies, about the pain, shame, and delight of incarnation. For Eric Weinstein, poetry may be vivisection, but vivisection is, for him, metaphysical, an art of awe and understanding, where it is not so much poetry as our own contradictions that rend us, that appear to us, in these pages, with such an arresting tension, between galaxy and microbe, flesh and metal, living and dead. These poems peer into the dark." --Joseph Donahue"Weinstein's VIVISECTION exposes the beating heart of its subjects with no loss of life: these remarkable poems are pensive yet urgent, allusive yet never needlessly elusive, grounded yet never sentimental. If this is surgical poetry, its implements--graceful precision, incisive thought, a meticulous accounting of the self's sacred and fungible parts--are wielded by a poet of significant subtlety and skill. 'I have a heart & so I know / how to make one, ' writes Weinstein--and the reader who fully registers the tensile structure and pulsing warmth of these poems is inclined to agree." --Seth Abramson"What is this quintessence of dust to me? Hamlet asks a flummoxed, completely overmatched duo pressed into the service of politicians, not more than a breath or two after he's exclaimed man to be a piece of work. As if in answer, Eric Weinstein launches VIVISECTION, this volley of vaulting philosophies. Here, the vehicles of body that give humankind its various and temporary residences are real, fragile, desirous, terrible pieces of work. In one poem after another, the hearts and the brains tough out another moment or month in their nearly involuntary quest to endure. But in the face of inexorable finitude, Weinstein's poems know and sing what we need to remember, what poems themselves remind us: that the brevity and transience that we might otherwise rue charges our existence with meaning. Detail by luminous detail, VIVISECTION insists on the value and significance of the vast co-op that is life, sentient and non-. In doing so, he implicates us in a sad and gorgeous summons to a world that we might otherwise only fear." --Marc McKee
