Arena (web Browser)
The Arena browser (also known as the Arena WWW Browser) was one of the first web browsers for Unix. Originally begun by Dave Raggett in 1993, development continued at CERN and the World Wide Web Consortium (W3C) and subsequently by Yggdrasil Computing. Arena was used in testing the implementations for HTML version 3.0, Cascading Style Sheets (CSS), Portable Network Graphics (PNG), and libwww. Arena was widely used and popular at the beginning of the World Wide Web. Arena, which predated Netscape Navigator and Microsoft's Internet Explorer, featured a number of innovations used later in commercial products. It was the first browser to support background images, tables, text flow around images, and inline mathematical expressions. The Arena browser served as the W3C's testbed browser from 1994 to 1996 when it was succeeded by the Amaya project. History In 1993, Dave Raggett, then at Hewlett-Packard (HP) in Bristol, England devoted his spare time to developing Arena on which he ...

Dave Raggett
Dave Raggett is an English computer specialist who has played a major role in implementing the World Wide Web since 1992. He has been a W3C Fellow at the World Wide Web Consortium since 1995 and worked on many of the key web protocols, including HTTP, HTML, XHTML, MathML, XForms, and VoiceXML. Raggett also wrote HTML Tidy and is currently pioneering W3C's work on the Web of Things. He lives in the west of England. Career From 1981 to 1984, Dave Raggett worked at Research Machines, designing and developing software for local networking of Z80 machines for use in schools. The following year, as a software developer in Hewlett-Packard's Office Productivity Division, he worked on remote printing solutions. From 1985 to 2000, Raggett worked as a researcher at Hewlett-Packard Labs in Bristol, England, where he pursued a variety of projects, including expert systems, hypertext, networking, Web browsers, and servers, embedded systems, interactive voice response systems. After he me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML Editor
An HTML editor is a program for editing HTML, the markup of a web page. Although the HTML markup in a web page can be controlled with any text editor, specialized HTML editors can offer convenience and added functionality. For example, many HTML editors handle not only HTML, but also related technologies such as CSS, XML and JavaScript or ECMAScript. In some cases they also manage communication with remote web servers via FTP and WebDAV, and version control systems such as Subversion or Git. Many word processing, graphic design and page layout programs that are not dedicated to web design, such as Microsoft Word or Quark XPress, also have the ability to function as HTML editors. Types of editors There are two main varieties of HTML editors: text and WYSIWYG (what you see is what you get) editors. Text editors Text editors intended for use with HTML usually provide at least syntax highlighting. Some editors additionally feature templates, toolbars and keyboard shortcuts to qui ...

World Wide Web
The World Wide Web (WWW), commonly known as the Web, is an information system enabling documents and other web resources to be accessed over the Internet. Documents and downloadable media are made available to the network through web servers and can be accessed by programs such as web browsers. Servers and resources on the World Wide Web are identified and located through character strings called uniform resource locators (URLs). The original and still very common document type is a web page formatted in Hypertext Markup Language (HTML). This markup language supports plain text, images, embedded video and audio contents, and scripts (short programs) that implement complex user interaction. The HTML language also supports hyperlinks (embedded URLs) which provide immediate access to other web resources. Web navigation, or web surfing, is the common practice of following such hyperlinks across multiple websites. Web applications are web pages that function as application s ...

Libwww
Libwww was an early World Wide Web software library providing core functions for browsers, implementing HTML, HTTP, and other technologies. Tim Berners-Lee, at CERN, released libwww (then also called the "Common Library") in late 1992, comprising reusable code from the first browsers (WorldWideWeb and Line Mode Browser). Libwww was relied upon by the popular browser Mosaic. By 1997, however, interest in libwww declined, and the W3C (which took over from CERN) reduced its commitment to the project. Later, the purpose of libwww was redefined to be "a testbed for protocol experiments", and in that vein it was maintained for the benefit of the W3C's standards-promoting browser Amaya. Active development of libwww stopped in 2000. libcurl is considered to be a modern replacement for libwww. History In 1991 and 1992, Tim Berners-Lee and a student at CERN named Jean-François Groff rewrote various components of the original WorldWideWeb browser for the NeXTstep operating system in p ...

Portable Network Graphics
Portable Network Graphics (PNG, officially pronounced , colloquially pronounced ) is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) — unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF". PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics; therefore non-RGB color spaces such as CMYK are not supported. A PNG file contains a single image in an extensible structure of ''chunks'', encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. PNG files use the file extension PNG or png and hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cascading Style Sheets
Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language such as HTML or XML (including XML dialects such as SVG, MathML or XHTML). CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript. CSS is designed to enable the separation of content and presentation, including layout, colors, and fonts. This separation can improve content accessibility; provide more flexibility and control in the specification of presentation characteristics; enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, which reduces complexity and repetition in the structural content; and enable the .css file to be cached to improve the page load speed between the pages that share the file and its formatting. Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering metho ...

HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by ''tags'', written using angle brackets. Tags such as and directly introduce content into the page. Other tags such as surround ...

Web Browser
A web browser is application software for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones. In 2020, an estimated 4.9 billion people used a browser. The most used browser is Google Chrome, with a 65% global market share on all devices, followed by Safari with 18%. A web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed. In some technical contexts, browsers are referred to as user agents. Function The purpose of a web browser is to fetch content from the World Wide Web or from local storage and display it on a user's device. This process ...

Scientific Linux
Scientific Linux (SL) was a Linux distribution produced by Fermilab, CERN, DESY and by ETH Zurich. It is a free and open-source operating system based on Red Hat Enterprise Linux. This product is derived from the free and open-source software made available by Red Hat, but is not produced, maintained or supported by them. In April 2019, it was announced that feature development for Scientific Linux would be discontinued, but that maintenance will continue to be provided for the 6.x and 7.x releases through the end of their life cycles. Fermilab and CERN will utilize CentOS Stream and AlmaLinux for their deployment of 8.x release instead. History Fermilab already had a Linux distribution known as Fermi Linux, a long-term support release based on Red Hat Enterprise Linux. CERN was creating their next version of CERN Linux, also based on RHEL. CERN contacted Fermilab about doing a collaborative release. Connie Sieh was the main developer and driver behind the first prototypes an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
