Practical Ruby Projects: Practical Ruby Projects Ideas for the Eclectic Programmer
CYAN YELLOW MAGENTA BLACK PANTONE 123 C BOOKS FOR PROFESSIONALS BY PROFESSIONALS® THE EXPERT’S VOICE® IN OPEN SOURCE Companion eBook Available Practical Ruby Projects: Projects Ruby Practical Ideas for the Eclectic Programmer Dear Reader, You’ve learned the basics of Ruby, and you’re ready to move on to the next level— trying out advanced techniques, mastering best practices, and exploring Ruby’s full potential. With this book you’ll learn by experience while you tackle an exciting series of varied but always practical programming projects. What is an eclectic programmer, you ask? He or she is an inquisitive thinker Practical who likes to play around with new concepts, a person who is project-oriented and enjoys coding, a person who doesn’t mind some technical depth folded in with creative excursions, and a person who is always looking for fresh ideas. This book is a little different from other computer books. It is meant to be entertaining, exciting, and intellectually challenging. Inside you’ll find a collec- tion of diverse projects, ranging from the creative to the practical, written as a nod to all the great Rubyists I’ve been privileged to know. Each chapter dives into Ruby Projects new topics and approaches meant to exercise your programming muscles. You’ll start by building a cross-platform music environment, progress to drawing animations using scalable vector graphics, and then move on to prac- tical problem solving using simulation. In addition, you’ll implement your own turn-based strategy game and build a Mac-native RubyCocoa interface to it. -

The Ruby Intermediate Language ∗
The Ruby Intermediate Language ∗ Michael Furr Jong-hoon (David) An Jeffrey S. Foster Michael Hicks University of Maryland, College Park ffurr,davidan,jfoster,[email protected] Abstract syntax that is almost ambiguous, and a semantics that includes Ruby is a popular, dynamic scripting language that aims to “feel a significant amount of special case, implicit behavior. While the natural to programmers” and give users the “freedom to choose” resulting language is arguably easy to use, its complex syntax and among many different ways of doing the same thing. While this ar- semantics make it hard to write tools that work with Ruby source guably makes programming in Ruby easier, it makes it hard to build code. analysis and transformation tools that operate on Ruby source code. In this paper, we describe the Ruby Intermediate Language In this paper, we present the Ruby Intermediate Language (RIL), (RIL), an intermediate language designed to make it easy to ex- a Ruby front-end and intermediate representation that addresses tend, analyze, and transform Ruby source code. As far as we are these challenges. RIL includes an extensible GLR parser for Ruby, aware, RIL is the only Ruby front-end designed with these goals in and an automatic translation into an easy-to-analyze intermediate mind. RIL provides four main advantages for working with Ruby form. This translation eliminates redundant language constructs, code. First, RIL’s parser is completely separated from the Ruby in- unravels the often subtle ordering among side effecting operations, terpreter, and is defined using a Generalized LR (GLR) grammar, and makes implicit interpreter operations explicit. -

Unifying Fixnum and Bignum Into Integer
Unifying Fixnum and Bignum into Integer Tanaka Akira @tanaka_akr 2016-09-08 National Institute of Advanced Industrial Science and Technology (AIST) Announcement ● Ruby 2.4 unify Fixnum and Bignum into Integer [Feature #12005] by naruse ● For Ruby programmers – Fixnum class and Bignum class are removed – 1.class and (2**100).class returns Integer instead of Fixnum and Bignum – The constants, Fixnum and Bignum, references Integer class (NameError will not occur) ● For C programmers – No internal representation change – The global constants, rb_cFixnum and rb_cBignum, are removed (compilation error will occur) – Class based dispatch doesn't work anymore Use FIXNUM_P(obj) and RB_TYPE_P(obj, T_BIGNUM) – RUBY_INTEGER_UNIFICATION macro is defined (for extension library supporting old and new Ruby) Fixnum and Bignum Ruby 2.3 has three classes to represent integers ● Integer: abstract super class – Fixnum: class for small integers – Bignum: class for big integers ● Examples – 1.class => Fixnum – (2**100).class => Bignum Integer Unification Ruby 2.4 has one class to represent integers ● Integer: concrete class ● Examples – 1.class => Integer – (2**100).class => Integer Integer Implementations The range of Fixnum varies ● 32bit CRuby (ILP32): –230 to 230–1 ● 64bit CRuby (LLP64): –230 to 230–1 ● 64bit CRuby (LP64): –262 to 262–1 ● JRuby: –263 to 263–1 The range is not portable Integer Specification ● The specification – ISO/IEC 30170:2012 Information technology -- Programming languages -- Ruby – JIS X 3017:2011 プログラム言語Ruby ● It specifies: – There is Integer class which range is unbounded – Implementation may (or may not) define subclasses of Integer – I.e. Fixnum and Bignum class are not defined (but permitted) ● Ruby 2.3 and Ruby 2.4 conforms the specification ● Conforming program should not depend on Fixnum, Bignum and their range Fixnum and Bignum is Implementation Detail ● The range of Fixnum varies Ruby program should not depend on the range for portability ● The spec. -

Arduino: a Quick-Start Guide
Download from Wow! eBook <www.wowebook.com> What Readers Are Saying About Arduino: A Quick-Start Guide The most comprehensive book on the Arduino platform I have read. Loaded with excellent examples and references, Arduino: A Quick-Start Guide gets beginners up and running in no time and provides experi- enced developers with a wealth of inspiration for their own projects. Haroon Baig Creator of the Twitwee Clock, http://www.haroonbaig.com Excellently paced for those who have never experimented with elec- tronics or microcontrollers before and packed with valuable tidbits even for advanced Arduino tinkerers. Georg Kaindl Creator, Arduino DHCP, DNS, and Bonjour libs The Arduino platform is a great way for anyone to get into embedded systems, and this book is the road map. From first baby steps to com- plex sensors and even game controllers, there is no better way to get going on the Arduino. T o n y Williamitis Senior embedded systems engineer I recommend this engaging and informative book to software develop- ers who want to learn the basics of electronics, as well as to anyone looking to interface their computers with the physical world.
