Beginning Ruby From Novice to Professional
Ruby is a fun toy. It’s also a serious programming language. Ruby is the jolly uncle who keeps the kids entertained, but who puts in solid 12-hour days at the construction site during the week. To hundreds of thousands of programmers, Ruby has become a good friend, a trusted servant, and has revealed a new way of thinking about programming and software development.
Like the guitar, it’s often claimed that Ruby is an easy language to learn and a hard one to master. I’d agree, with some provisions. If you don’t know any programming languages already, Ruby will be surprisingly easy to learn. If you already know some languages such as PHP, Perl, BASIC, C, or Pascal, some of the concepts in Ruby will already be familiar to you, but the different perspective Ruby takes with problem solving will probably throw you at first. Like the differences between spoken languages, Ruby differs from most other programming languages not only by syntax, but by culture, grammar, and customs. In fact, Ruby has more in common with more esoteric languages such as LISP and Smalltalk than with better-known languages such as PHP and C++.
While Ruby’s roots might be different from other languages, it’s heavily used and respected in many industries. Companies that use or support Ruby in one way or another include such prestigious names as Sun Microsystems, Intel, Microsoft, Apple, and Amazon.com. The Ruby on Rails Web framework is a system for developing Web applications that uses Ruby as its base language, and it powers hundreds of large Web sites. Ruby is also used as a generic language from the command prompt, much like Perl.
