Puma (web Server)
Puma is an HTTP web server derived from Mongrel and written by Evan Phoenix. It stresses speed and efficient use of memory. Reception and use Puma is the web server shipped with Mastodon and recommended by the Heroku hosting provider as a replacement for Unicorn. Deliveroo Deliveroo is a British online food delivery company founded by Will Shu and Greg Orlowski in 2013 in London, England. It operates in the United Kingdom, France, Belgium, Ireland, Italy, Singapore, Hong Kong, the United Arab Emirates and Kuwait ... published a benchmark comparing the two servers and concluded “Puma performs better than Unicorn in all tests that were either heavily IO-bound or that interleaved IO and CPU work”, but that Unicorn was still slightly better performing in situations where CPU load was the limiting factor.

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 ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, t ...

Web Server
A web server is computer software and underlying hardware that accepts requests via HTTP (the network protocol created to distribute web content) or its secure variant HTTPS. A user agent, commonly a web browser or web crawler, initiates communication by making a request for a web page or other resource using HTTP, and the server responds with the content of that resource or an error message. A web server can also accept and store resources sent from the user agent if configured to do so. The hardware used to run a web server can vary according to the volume of requests that it needs to handle. At the low end of the range are embedded systems, such as a router that runs a small web server as its configuration interface. A high-traffic Internet website might handle requests with hundreds of servers that run on racks of high-speed computers. A resource sent from a web server can be a preexisting file (static content) available to the web server, or it can be generated ...

BSD Licenses
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses. BSD is both a license and a class of license (generally referred to as BSD-like). The modified BSD license (in wide use today) is very similar to the license originally used for the BSD version of Unix. The BSD license is a simple license that merely requires that all code retain the BSD license notice if redistributed in source code format, or reproduce the notice if redistributed in binary format. The BSD license (unlike some other licenses e.g. GPL) does not require that source code be distributed at all. Terms In addition to ...

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] |
Computer Memory
In computing, memory is a device or system that is used to store information for immediate use in a computer or related computer hardware and digital electronic devices. The term ''memory'' is often synonymous with the term ''primary storage'' or '' main memory''. An archaic synonym for memory is store. Computer memory operates at a high speed compared to storage that is slower but less expensive and higher in capacity. Besides storing opened programs, computer memory serves as disk cache and write buffer to improve both reading and writing performance. Operating systems borrow RAM capacity for caching so long as not needed by running software. If needed, contents of the computer memory can be transferred to storage; a common way of doing this is through a memory management technique called ''virtual memory''. Modern memory is implemented as semiconductor memory, where data is stored within memory cells built from MOS transistors and other components on an integrated c ...

Mastodon (software)
Mastodon is free and open-source software for running self-hosted social networking services. It has microblogging features similar to Twitter, which are offered by a large number of independently run nodes, known as instances, each with its own code of conduct, terms of service, privacy policy, privacy options, and content moderation policies. Each user is a member of a specific Mastodon instance (also called a server), which can interoperate as a federated social network, allowing users on different instances to interact with each other. This is intended to give users the flexibility to select a node whose policies they prefer, but keep access to a larger social network. Mastodon is also part of the Fediverse ensemble of server platforms, which use shared protocols allowing users to also interact with users on other compatible platforms, such as PeerTube and Friendica. Mastodon is crowdfunded and does not contain ads. Mastodon was created by Eugen Rochko and announced on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium (website)
Medium is an American online publishing platform developed by Evan Williams and launched in August 2012. It is owned by A Medium Corporation. The platform is an example of social journalism, having a hybrid collection of amateur and professional people and publications, or exclusive blogs or publishers on Medium, and is regularly regarded as a blog host. Williams, previously co-founder of Blogger and Twitter, initially developed Medium as a means to publish writings and documents longer than Twitter's 140-character (now 280-character) maximum. In March 2021, Medium announced a change in its publishing strategy and business model. The change is to its mix of paid journalists working on its own publications – this will be proportionally reduced – versus its support of independent writers, which will increase. History 2012 (launched) - 2016 Evan Williams, Twitter co-founder and former CEO, created Medium to encourage users to create posts longer than the then 140-character ...

Heroku
Heroku is a cloud platform as a service (PaaS) supporting several programming languages. One of the first cloud platforms, Heroku has been in development since June 2007, when it supported only the Ruby programming language, but now supports Java, Node.js, Scala, Clojure, Python, PHP, and Go. For this reason, Heroku is said to be a polyglot platform as it has features for a developer to build, run and scale applications in a similar manner across most languages. Heroku was acquired by Salesforce in 2010 for $212 million. History Heroku was initially developed by James Lindenbaum, Adam Wiggins, and Orion Henry for supporting projects that were compatible with the Ruby programming platform known as Rack. The prototype development took around six months. Later on, Heroku faced setbacks because of lack of proper market customers as many app developers used their own tools and environment. In January 2009, a new platform was launched which was built almost from scratch after a th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicorn (web Server)
Unicorn is a Rack HTTP server to serve Ruby web applications on UNIX environment. It is optimised to be used with nginx. It is based on now deprecated Mongrel 1.1.5 from 2008. Architecture Unicorn uses a master/worker architecture, where a master process forks worker processes and controls them. The application runs in a single thread. Reception and use Unicorn was considered as “one of the most popular servers for Rails”. Twitter started to test Unicorn in 2010. This server is shipped with Discourse. Their system administrator Sam Saffron noted Unicorn was reliable, as it reaps unresponsive workers. Unicorn inspired other projects like Gunicorn, a fork to run Python applications. As of 2018, projects tend to favour Puma. The Heroku hosting provider recommends since 2015 to migrate from Unicorn to Puma. Deliveroo published a benchmark comparing the two servers and concluded “Puma performs better than Unicorn in all tests that were either heavily IO-bound or that interl ...
