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] |
NGINX
Nginx (pronounced "engine x" ) is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The software was created by Igor Sysoev and publicly released in 2004. Nginx is free and open-source software, released under the terms of the 2-clause BSD license. A large fraction of web servers use Nginx, often as a load balancer. A company of the same name was founded in 2011 to provide support and ''Nginx Plus'' paid software. In March 2019, the company was acquired by F5, Inc. for $670 million. Popularity W3Tech's web server count of all web sites ranked Nginx first with 33.6%. Apache was second at 31.4% and Cloudflare Server third at 21.6%. , Netcraft estimated that Nginx served 22.01% of the million busiest websites with Apache a little ahead at 23.04%. Cloudflare at 19.53% and Microsoft Internet Information Services at 5.78% rounded out the top four servers for the busiest websites. Some of Netcraft's other statistics show Ngi ...

Comparison Of Web Server Software
Web server software allows computers to act as web servers. The first web servers supported only static files, such as HTML (and images), but now they commonly allow embedding of server side applications. Some web application frameworks include simple HTTP servers. For example the Django framework provides runserver, and PHP has a built-in server. These are generally intended only for use during initial development. A production server will require a more robust HTTP front-end such as one of the servers listed here. Overview Features Some features may be intentionally not included to web server to avoid featuritis. For example: * TLS/HTTPS may be enabled with a separate stunnel daemon that terminates TLS and redirects raw HTTP packets to http daemon. * NGINX and OpenBSD httpd authors decided not to include CGI interpretation but instead use FastCGI. For OpenBSD was developed a ''slowcgi'' gateway. * BusyBox httpd doesn't have automatically generated directory listing but ...

Process Management (computing)
A process is a program in execution, and an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes. To meet these requirements, the OS must maintain a data structure for each process, which describes the state and resource ownership of that process, and which enables the OS to exert control over each process. Multiprogramming In any modern operating system there can be more than one instance of a program loaded in memory at the same time. For example, more than one user could be executing the same program, each user having separate copies of the program loaded into memory. With some programs, it is possible to have one copy loaded into memory, while several users have shared access to it so that they each can execute the same program-code. Such a program is said to be re-entrant. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Python Paste
Python Paste, often simply called paste, is a set of utilities for web development in Python. Paste has been described as "a framework for web frameworks". The Python Paste package contains Python modules that help in implementing WSGI middleware. The package includes a WSGI wrapper for CGI applications. It also includes a simple webserver that can produce WSGI requests. WSGI middleware The WSGI standard is an interface that allows applications to use Python code to handle HTTP requests. A WSGI application is passed a Python representation of an HTTP request by an application, and returns content which will normally eventually be rendered by a web browser. A common use for this is when a web server serves content created by Python code. There are, however, other uses: WSGI middleware is Python code that receives a WSGI request and then performs logic based upon this request, before passing the request on to a WSGI application or more WSGI middleware. WSGI middleware appears ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Django (web Framework)
Django ( ; sometimes stylized as django) is a free and open-source, Python-based web framework that follows the model–template–views (MTV) architectural pattern. It is maintained by the Django Software Foundation (DSF), an independent organization established in the US as a 501(c)(3) non-profit. Django's primary goal is to ease the creation of complex, database-driven websites. The framework emphasizes reusability and "pluggability" of components, less code, low coupling, rapid development, and the principle of don't repeat yourself. Python is used throughout, even for settings, files, and data models. Django also provides an optional administrative create, read, update and delete interface that is generated dynamically through introspection and configured via admin models. Some well-known sites that use Django include Instagram, Mozilla, Disqus, Bitbucket, Nextdoor and Clubhouse. History Django was created in the fall of 2003, when the web programmers at the ''Lawre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web2py
Web2py is an open-source web application framework written in the Python programming language. Web2py allows web developers to program dynamic web content using Python. Web2py is designed to help reduce tedious web development tasks, such as developing web forms from scratch, although a web developer may build a form from scratch if required.Web2py (2013), What is web2py?, web2py.com, retrieved 11 October 2013, Web2py was originally designed as a teaching tool with emphasis on ease of use and deployment. Therefore, it does not have any project-level configuration files. The design of web2py was inspired by the Ruby on Rails and Django frameworks. Like these frameworks, web2py focuses on rapid development, favors convention over configuration approach and follows a model–view–controller (MVC) architectural pattern. Overview Web2py is a full-stack framework in that it has built-in components for all major functions, including: * HTTP requests, HTTP responses, cookies, se ...

Tornado (web Server)
Tornado is a scalable, non-blocking web server and web application framework written in Python. It was developed for use by FriendFeed; the company was acquired by Facebook in 2009 and Tornado was open-sourced soon after. Performance Tornado is noted for its high performance. Its design enables handling a large number of concurrent connections (i.e., tries to solve the "C10k problem"). Modules * An asynchronous MongoDB driver called Motor. * CouchDB drivers called corduroy and trombi. * Asynchronous driver for PostgreSQL wrapping psycopg called Momoko Example The following code shows a simple web application that displays "Hello World!" when visited: import asyncio import tornado.web class MainHandler(tornado.web.RequestHandler): def get(self): self.write("Hello, world") def make_app(): return tornado.web.Application( r"/", MainHandler), async def main(): app = make_app() app.listen(8888) await asyncio.Event().wait() if __name__ "__main__" ...

Web Framework
A web framework (WF) or web application framework (WAF) is a software framework that is designed to support the development of web applications including web services, web resources, and web APIs. Web frameworks provide a standard way to build and deploy web applications on the World Wide Web. Web frameworks aim to automate the overhead associated with common activities performed in web development. For example, many web frameworks provide libraries for database access, templating frameworks, and session management, and they often promote code reuse. Although they often target development of dynamic web sites, they are also applicable to static websites. History As the design of the World Wide Web was not inherently dynamic, early hypertext consisted of hand-coded HTML text files that were published on web servers. Any modifications to published pages needed to be performed by the pages' author. In 1993, the Common Gateway Interface (CGI) standard was introduced for interfa ...

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 ...
