Ruby






 
Ruby
Ruby is a dynamic, reflective, object-oriented, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.
According to its authors, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, and Lisp. It supports multiple programming paradigms, including functional, object-oriented, and imperative. It also has a dynamic type system and automatic memory management.

History

Early concept

Ruby was conceived on February 24, 1993. In a 1999 post to the ruby-talk mailing list, Ruby author Yukihiro Matsumoto describes some of his early ideas about the language:
I was talking with my colleague about the possibility of an object-oriented scripting language. I knew Perl (Perl4, not Perl5), but I didn't like it really, because it had the smell of a toy language (it still has). The object-oriented language seemed very promising. I knew Python then. But I didn't like it, because I didn't think it was a true object-oriented language — OO features appeared to be add-on to the language. As a language maniac and OO fan for 15 years, I really wanted a genuine object-oriented, easy-to-use scripting language. I looked for but couldn't find one. So I decided to make it.
Matsumoto describes the design of Ruby as being like a simple Lisp language at its core, with an object system like that of Smalltalk, blocks inspired by higher-order functions, and practical utility like that of Perl.

The name "Ruby"

The name "Ruby" originated during an online chat session between Matsumoto and Keiju Ishitsuka on February 24, 1993, before any code had been written for the language.Initially two names were proposed: "Coral" and "Ruby". Matsumoto chose the latter in a later e-mail to Ishitsuka.Matsumoto later noted a factor in choosing the name "Ruby" – it was the birthstone of one of his colleagues.

Ruby  Founder:

Yukihiro Matsumoto

Yukihiro Matsumoto Matsumoto Yukihiro, a.k.a. Matz, born 14 April 1965) is a Japanese computer scientist and software programmer best known as the chief designer of the Ruby programming language and its reference implementation, Matz's Ruby Interpreter (MRI). His demeanor has brought about a motto in the Ruby community "Matz is nice and so we are nice," commonly abbreviated as MINASWAN.
As of 2011, Matsumoto is the Chief Architect of Ruby at Heroku, an online cloud platform-as-a-service in San Francisco. He is a fellow of Rakuten Institute of Technology, a research and development organisation in Rakuten Inc. He was appointed to the role of technical advisor for VASILY, Inc. starting in June 2014.
Matsumoto's name can be written using kanji: , but is normally written using hiragana:

 Born in Osaka Prefecture, Japan, he was raised in Tottori Prefecture from the age of four. According to an interview conducted by Japan Inc., he was a self-taught programmer until the end of high school. He graduated with an information science degree from University of Tsukuba, where he was a member of Ikuo Nakata's research lab on programming languages and compilers.

He worked for the Japanese open source company, netlab.jp. Matsumoto is also known as one of the open source evangelists in Japan. He's released several open source products, including cmail, the Emacs-based mail user agent, written entirely in Emacs Lisp. Ruby is his first piece of software that has become known outside of Japan.

Java programming language

Java, modern object-oriented computer programming language. Java was created at Sun Microsystems , Inc., where cofounder William (Bill) Joy led a team of researchers in an effort to create a new language that would allow consumer electronic devices to communicate with each other. Work on the language began in 1991, and before long the team’s focus changed to a new niche, the World Wide Web. Java was first used on the Web in 1994, and Java’s ability to provide interactivity and multimedia showed that it was particularly well suited for the Web. The difference between the way Java and other programming languages worked was revolutionary. Code in other languages is first translated by a compiler into instructions for a specific type of computer. The Java compiler instead turns code into something called Bytecode, which is then interpreted by software called the Java Runtime Environment (JRE), or the Java virtual machine. The JRE acts as a virtual computer that interprets Byte...
