Zed Shaw
Zed A. Shaw is a software developer best known for creating the ''Learn Code the Hard Way'' series of programming tutorials, as well as for creating the Mongrel web server for Ruby web applications. He is also well known for his polemical views on programming languages and communities. Software Shaw authored the Mongrel web server for Ruby web applications. Mongrel was the first web server used by Twitter, and inspired Node.js, according to its creator Ryan Dahl. Mongrel2 is the language-agnostic successor to Mongrel. He has also written a Python mail server called Lamson, on which the mailing list site LibreList is built. Learn Code the Hard Way Shaw is the author of learncodethehardway.org, which offers to teach users Python, Ruby, C, Regex, and SQL. Polemics and controversies Shaw has been outspoken in his criticism of certain programming language and technical communities.

Mongrel (web Server)
Mongrel is an open-source software HTTP library and web server written in Ruby by Zed Shaw. It is used to run Ruby web applications and presents a standard HTTP interface. This makes layering other servers in front of it possible using a web proxy, a load balancer, or a combination of both, instead of having to use more conventional methods employed to run scripts such as FastCGI or SCGI to communicate. This is made possible by integrating a custom high-performance HTTP request parser implemented using Ragel. Mongrel was the first web server used by Twitter, and inspired Node.js according to Ryan Dahl. Shaw subsequently created Mongrel2, an open-source " language agnostic" web server and the successor to Mongrel server. Deployment One popular configuration was to run Apache HTTP Server 2.2 as a load balancer using mod_proxy_balancer in conjunction with several Mongrel instances. Each Mongrel instance would run on a separate TCP port, configured via the mongrel_cluster manageme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby (programming Language)
Ruby is an interpreted, high-level, general-purpose programming language which supports multiple programming paradigms. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types. It was developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan. Ruby is dynamically typed and uses garbage collection and just-in-time compilation. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. According to the creator, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, BASIC, Java and Lisp. History Early concept Matsumoto has said that Ruby was conceived in 1993. In a 1999 post to the ''ruby-talk'' mailing list, he describes some of his early ideas about the language: 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-o ...

Ryan Dahl
Ryan Dahl (born 1981) is an American software engineer who is best known for creating the Node.js JavaScript runtime as well as the Deno JavaScript/TypeScript runtime. Biography Dahl grew up in San Diego, California. His mother bought him an Apple IIc when he was six years old, one of his first experiences with technology. Dahl attended a community college in San Diego and later transferred into UC San Diego where he studied mathematics. He went on to attend grad school for Mathematics at the University of Rochester where he studied algebraic topology, which he found "very abstract and beautiful" for a couple of years but later got bored of it because "it was not so applicable to real life". Ruby work After graduating, Dahl entered a Ph.D. program, but eventually dropped out, since he did not want to devote the rest of his life to mathematics. Instead, he left for South America, where he started developing web applications in Ruby. Node.js On May 27, 2009, Dahl released his ...

Mongrel2
Mongrel2 is an open-source "language agnostic" web server written by Zed Shaw, and is the successor to Shaw's Mongrel server. The server supports HTTP, Flash XMLSockets, WebSocket WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as in 2011. The current API specification allowing web applications ...s and long polling connections. Language agnostic Mongrel2 is described as language agnostic, meaning it does not prefer any specific programming language over another. The server's documentation says: Development Shaw began working on the server in June 2010 and released version 1.0 of the software on September 1, 2010. Mongrel2 has nothing in common with the original Mongrel webserver, except for using the same HTTP parser.

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby On Rails
Ruby on Rails (simplified as Rails) is a server-side web application framework written in Ruby under the MIT License. Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer and HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern. Ruby on Rails' emergence in 2005 greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Pyt ...

History Of Python
The programming language Python was conceived in the late 1980s, and its implementation was started in December 1989 by Guido van Rossum at CWI in the Netherlands as a successor to ABC capable of exception handling and interfacing with the Amoeba operating system. Van Rossum is Python's principal author, and his continuing central role in deciding the direction of Python is reflected in the title given to him by the Python community, ''Benevolent Dictator for Life'' (BDFL). (However, van Rossum stepped down as leader on July 12, 2018.). Python was named after the BBC TV show '' Monty Python's Flying Circus''. Python 2.0 was released on October 16, 2000, with many major new features, including a cycle-detecting garbage collector (in addition to reference counting) for memory management and support for Unicode. However, the most important change was to the development process itself, with a shift to a more transparent and community-backed process. Python 3.0, a major, backw ...

Pair Programming
Pair programming is an software development technique in which two programmers work together at one workstation. One, the ''driver'', writes code while the other, the ''observer'' or ''navigator'', reviews each line of code as it is typed in. The two programmers switch roles frequently. While reviewing, the observer also considers the "strategic" direction of the work, coming up with ideas for improvements and likely future problems to address. This is intended to free the driver to focus all of their attention on the "tactical" aspects of completing the current task, using the observer as a safety net and guide. Economics Pair programming increases the person-hours required to deliver code compared to programmers working individually. However, the resulting code has fewer defects. Along with code development time, other factors like field support costs and quality assurance also figure into the return on investment. Pair programming might theoretically offset these expenses by re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain Gang
A chain gang or road gang is a group of prisoners chained together to perform menial or physically challenging work as a form of punishment. Such punishment might include repairing buildings, building roads, or clearing land. The system was notably used in the convict era of Australia and in the Southern United States. By 1955 it had largely been phased out in the U.S., with Georgia among the last states to abandon the practice. North Carolina continued to use chain gangs into the 1970s. Chain gangs were reintroduced by a few states during the " get tough on crime" 1990s: in 1995 Alabama was the first state to revive them. The experiment ended after about one year in all states except Arizona, where in Maricopa County inmates can still volunteer for a chain gang to earn credit toward a high school diploma or avoid disciplinary lockdowns for rule infractions.
