Apache

Apache é uma abreviação deApache HTTP Server Project , HTTP Web Serversoftware robusto, de nível comercial, com mais recursos e livremente disponível em código aberto, produzido [pela http://www.apache.org/ Apache Software Foundation]. É o servidor web mais utilizado na internet e está disponível em diversas plataformas, incluindo Windows, Unix e Mac OS X. Apache serve como uma ótima base para a publicação de sites WordPress.

Array

Um array é uma das estruturas de dados básicos usados em programação de computadores. Um array contém uma lista (ouvetor) de itens como valores numéricos ou strings. Arrays permitem aos programadores acesso a dados de forma aleatória. Os dados podem ser armazenados em arrays unidimensional ou multi-dimensional arrays

Uma matriz unidimensional de sete (7) elementos:

105200545310213405

As Tags de Modelos, como Tags de Modelos/wp_list_categories() usa uma matriz unidimensional para a "excluir" parâmetros.

Um exemplo de matriz bidimensional, 7 por 3 elementos em tamanho:

105200545310213405
1521014513223134512
501500499488552751952

ASCII

ASCII (acrônimo para American Standard Code for Information Interchange, que em português significa 'Código Padrão Americano para o Intercâmbio de Informação') é uma codificação de caracteres de oito bits baseada no alfabeto inglês.

Os códigos ASCII representam texto em computadores, equipamentos de comunicação, entre outros dispositivos que trabalham com texto. Desenvolvida a partir de 1960, grande parte das codificações de caracteres modernas a herdaram como base.

Atom

Ao contrário do RSS, Atom não é uma sigla, mas também é um formato para divulgação de notícias.

Atom é o nome dado a um estilo baseado em conteúdo XML e metadados, ou seja, é um protocolo ao nível da aplicação para publicar e editar Fontes web que são periodicamente atualizadas, como por exemplo Blogs.

Os feeds devem ser formados em formato XML e são identificados como application/atom+xml media type.

O funcionamento deles não difere das Markup Languages tradicionais, com cabeçalhos, títulos e corpo como no HTML 4.0.

Avatar

A representação visual de um utilizador em informática. De acordo com a tecnologia, pode variar desde um sofisticado modelo 3D até uma simples imagem.

São normalmente pequenos, de tamanhos variados mas deixando espaço livre para a função principal do site, programa ou jogo que se está a usar.

Banco de Dados

A Banco de Dados in computing terms is software used to manage information in an organized fashion. WordPress uses the MySQL relational database management system for storing and retrieving the content of your blog, such as posts, comments, and so on.

Barra Lateral

A Barra Lateral, sometimes called the menu, is a narrow vertical column often jam-packed with lots of information about a website. Found on most WordPress sites, the sidebar is usually placed on the right or left-hand side of the web page, though in some cases, a site will feature two sidebars, one on each side of the main content where your posts are found. A sidebar is also referred to as a Theme Template file and is typically called sidebar.php.

Binários

Binários se referem a programas de computador compilados, ou executáveis. Muitos projetos em Código aberto , que pode ser re-compilado a partir de Código-fonte, oferecem binários pré-compilados para as plataformas mais populares e sistemas operacionais.

Blog

Um blog (contração do termo Web log), também chamado de blogue, é um site cuja estrutura permite a atualização rápida a partir de acréscimos dos chamados artigos, ou postagens. Estes são, em geral, organizados de forma cronológica inversa, tendo como foco a temática proposta do blog, podendo ser escritos por um número variável de pessoas, de acordo com a política do blog.

Os blogues são tipicamente usados por indivíduos ou grupos, mas ocasionalmente são utilizados por empresas ou organizações também.

Blogs geralmente podem ser públicos, ou com conteúdo privado. Dependendo da funcionalidade do software CMS que é usado, alguns autores podem restringir o acesso - por meio do uso de contas ou senhas - para conteúdo que é muito pessoal a ser divulgado publicamente.

Blogar

Blogar é a palavra aportuguesada de blogging, o ato de publicar através de Blogs.

Blogosfera

Blogosfera é o termo coletivo que compreende todos os weblogs (ou blogs) como uma comunidade ou rede social.

  • Veja também: [pt.wikipedia.org/wiki/Blogosfera Blogosfera no Wikipédia]

Blogroll

Um blogroll é um conjunto de links. Permite saber quais outros blogs você lê e quais tipos de coisas interessam a você.

Bookmarklet

Uma bookmarklet (ou FaveLet) é um link adicionado aos seus Links Favoritos mas que em vez de uma link para um site, contém uma função geralmente em JavaScript, que permite alguma ação.

Boolean

Boolean são parâmetros que fornecem uma avaliação simples verdadeiro/falso.

Caminho Absoluto

Um Caminho Absoluto (absolute path ou full path em inglês) é o local único de um nome de arquivo ou diretório dentro de uma computador ou sistema de arquivos, geralmente começa com o diretório raiz ou letra de unidade. Diretórios e subdiretórios listados em um caminho geralmente são separados por uma barra /.

Examplo: /Users/Matt/www/blog/imagens/carro.jpg

Para encontrar o Caminho Absoluto de uma página, copie o exemplo a seguir em um arquivo de texto simples, salve o arquivo como path.php. Então abra o arquivo através do navegador (por examplo, http://www.examplo.com/imagens/path.php).

 <?php
 $p = getcwd();
 echo $p;
 ?>

Caminho Relativo

Um Caminho Relativo (relative path em inglês) é a localização de um arquivo em relação ao diretório atual de trabalho e não começando com barra (/). Isso é diferente de um Caminho Absoluto que dá a localização exata do arquivo.

Categoria

Each postagem no WordPress é arquivada em uma categoria. Categorização atenciosas permitem que postagens sejam agrupadas com outras de conteúdo semelhante e ajuda na navegação de uma site. Por favor note, a categoria postagem não deve ser confundida com Categorias de Links usada para classificar e gerenciar links.

Capacidades

Termos relacionados com a autenticação de usuários e controle de acesso. É uma aprovação de permissões no modo RBAC. Há cerca de trinta capacidades em WordPress. Veja Papéis e Capacidades para uma descrição do conceito e uma Lista de Capacidades disponível.

CGI

CGI (Common Gateway Interface) is a specification for server-side communication scripts designed to transfer information between a Web server and a web-client (browser). Typically, HTML pages that collect data via forms use CGI programming to process the form data once the client submits it.

Código Aberto

Open source is simply programming code that can be read, viewed, modified, and distributed, by anyone who desires. WordPress is distributed under an open source GNU General Public License (GPL).

Conjunto de Caracteres

Um conjunto de caracteres é uma coleção de símbolos (letras, números, pontuação e caracteres especiais) que quando utilizados em conjunto, representam palavras significativas em um idioma.

Os computadores usam um esquema de codificação para que os membros de um conjunto de caracteres sejam armazenadas com um valor numérico (por exemplo, 0=A, 1=B, 2=C, 3=D). Além disso, um agrupamento determina a ordem (por exemplo alfabética) utilizados para ordenar o conjunto de caracteres.

Por padrão, o WordPress utiliza o Unicode UTF-8 caracteres (utf8) definidas para as tabelas do banco de dados MySQL WordPress criado durante o processo de instalação. Desde a versão 2.2, o conjunto de caracteres dobanco de dados (agrupamento) é definido no arquivo wp-config.php. Além disso, observe o conjunto de caracteres usado para feeds em Configurações > Leitura.

chmod

chmod is a Unix/Linux shell command used to change permissions on files. Its name is a contraction of "change mode."

Class

Classes are groupings of CSS styles which can be applied to any HTML element. For classes in PHP, see the Class (Computing) article at Wikipedia and PHP Manual: Classes and Objects.

Collation

Collation refers to the order used to sort the letters, numbers, and symbols of a given character set. For example, because WordPress, by default, uses the UTF-8 (utf8) character set, and when the WordPress MySQL database tables are created during the installation process, MySQL assigns utf8_general_ci collation to those table. Beginning with Version 2.2, the collation (and character set) used by WordPress is defined in the wp-config.php file.

Comentários

Comentários are a feature of blogs which allow readers to respond to posts. Typically readers simply provide their own thoughts regarding the content of the post, but users may also provide links to other resources, generate discussion, or simply compliment the author for a well-written post.

You can control and regulate comments by filters for language and content. Comments can be queued for approval before they are visible on the web site. This is useful in dealing with comment spam.

Conteúdo

Content consists of text, images, or other information shared in posts. This is separate from the structural design of a web site, which provides a framework into which the content is inserted, and the presentation of a site, which involves graphic design. A Content Management System changes and updates content, rather than the structural or graphic design of a web site.

CMS

A Content Management System, or CMS, is software for facilitating the maintenance of content, but not design, on a web site. A blogging tool is an example of a Content Management System.

cPanel

cPanel is a popular web-based administration tool that many hosting providers provide to allow users to configure their own accounts using an easy-to-use interface.

CSS

CSS, or Cascading Style Sheets, is a W3C open standards programming language for specifying how a web page is presented. It allows web site designers to create formatting and layout for a web site independently of its content.

Default theme

Every installation of WordPress has a default theme. The default theme is sometimes called the fallback theme, because if the active theme is for some reason lost or deleted, WordPress will fallback to using the default theme.

Up to Version 2.9.2 the default theme was the WordPress Default theme (sometimes call Kubrick) and was housed in the wp-content/themes/default folder. Starting with Version 3.0, the Twenty Ten theme became the default (and fallback) theme.

Desenvolvedor

A developer, or dev, is a computer programmer who is active in creating, modifying, and updating a software product.

DIV

A DIV element in HTML marks a section of text. DIVs are used extensively in WordPress to apply CSS stylings to particular blog elements.

DOM

DOM (Document Object Model) is a standard, platform-independent interface that allows programmers to dynamically access HTML and XML to control the content and structure of documents. DOM connects programming scripts to web pages.

Editor de Texto

Editor de Texto é um programa que edita arquivos em texto puro, em comparação com formato binário. Usar um editor de texto sem ser de texto puro, como o Microsoft Word para editar scripts em PHP pode causar grandes problemas no seu código. Isso é porque o editor de texto possui formatação como cores e tipos de fontes, que adicionam caracteres extras no arquivo, e isso não é interpretado corretamente pelo interpretador. Um editor como o Bloco de Notas, no entanto, não insere qualquer formatação extra.

Edite os arquivo do WordPress somente em editores de texto puro

Este são alguns exemplos de formato de arquivo que devem ser editados como texto puro:

Alguns exemplos de editores de texto puro, alguns gratuitos:

Exemplos de tipos de arquivos de texto não-puro e que precisam de software especial para edição:

  • Documentos do Microsoft Word, planilhas do Microsoft Excel
  • Imagens, como JPEG, PNG, ou GIF

Alguns exemplos de software que podem editar texto, mas que NÃO são considerado como editores de texto básico eNÃO são recomendados para uso em arquivos WordPress:

  • Microsoft Word
  • Microsoft Works
  • Microsoft Excel
  • Adobe Photoshop
  • Adobe Illustrator
  • Adobe Dreamweaver

Emoticons

Emoticons (also called Smilies or Smileys) are stylized representations of a human face, usually displayed as yellow buttons with two dots for the eyes, and a half mouth. Smileys are often used in WordPress Plugins. By default, WordPress automatically converts text smileys to graphic images. When you type ;-) in your post you see Wink Icon when you preview or publish your post.

Artigos relacionado: Using Smilies

Endereço IP

An Endereço IP is a unique number (e.g. 70.84.29.148) assigned to a computer (or other internet-capable information appliance, such as a network printer) to enable it to communicate with other devices using the Internet Protocol. It is a computer's identity on the internet, and every computer connected to the internet is assigned at least one — although the methods of assigning these addresses, and the permanence and duration of their assignment, differ according to the use of the computer and the circumstances of its internet use.

Every web server is assigned an IP address as well, but often times hosting providers will assign multiple IP addresses to one computer, in the event that multiple web sites reside on the same physical server. This is the case with most inexpensive 'managed' or 'group' hosting packages.

Domain names were created to provide an easier means of accessing internet resources than IP addresses, which are cumbersome to type and difficult to remember. Every domain name has at least one corresponding IP address, but only a small number of IP addresses have a domain name associated with them, since only computers that are web servers require domain names. The Domain Name System (DNS) is what maps Domain names to IP addresses.

Entidade de Caractere

Alguns caracteres são reservados em [[#HTML|HTML] e XHTML. Por exemplo, você não pode usar o sinal de maior > ou menor < dentro de seu texto, porque os browsers pode confundi-los com a marcação. Então se criou um conjunto de caracteres que representam um único símbolo.

&lt;  símbolo menor que (<)
&gt;  símbolo maior que(>)

O idioma português é vasto em acentuações e você já deve ter percebido que ao editar qualquer arquivo do WordPress, em vez de mostrar palavras acentuadas, o navegador mostra símbolos estranhos. Isso é porque devemos usar o código da entidade de caractere.

Nos arquivos do WordPress, devemos usar os códigos de tais letras acentuadas para que apareçam corretamente. Veja a tabela de caracteres HTML ISO-8859-1.

Feed

Feed (vindo do verbo em inglês "alimentar") é um formato de dados usado em formas de comunicação com conteúdo atualizado frequentemente, como sites de notícias ou blogs.

Distribuidores de informação, blogueiros ou canais de notícias disponibilizam um feed ao qual usuários podem se inscrever, no formato de um link. Outros formatos de dado possíveis de serem comunicados por feeds são arquivos de áudio, podcasts e vídeos.

FTP

FTP significa File Transfer Protocol (Protocolo de Transferência de Arquivos) e é uma forma bastante rápida e versátil de transferir arquivos (também conhecidos como ficheiros), sendo uma das mais usadas na internet.

Pode referir-se tanto ao protocolo quanto ao programa que implementa este protocolo (Servidor FTP, neste caso, tradicionalmente aparece em letras minúsculas, por influência do programa de transferência de arquivos do Unix).

Galeria

As defined by Andy Skelton, Gallery, introduced with WordPress 2.5, is specifically an exposition of images attached to a post. In that same vein, an upload is "attached to a post" when you upload it while editing a post.

In the uploader there is a "Gallery" tab that shows all the uploads attached to the post you are editing. When you have more than one attachment in a post, you should see at the bottom of the Gallery tab a button marked "Insert gallery into post". That button inserts a shortcode "[gallery]" into the post. WordPress replaces that shortcode with an exposition of all images attached to that post. Non-image file types are excluded from the gallery.

Note: If you don't see the "Insert galley into post" button, it may be because you have not attached two images to the post.

The pretty URLs for attachments are made only after you have published the post and should be composed as the post permalink plus the attachment slug.

GMT

GMT, or Greenwich Mean Time, is the time zone from which all other time zones are measured. Local times around the globe are calculated according to their offset from the time in Greenwich, England.

Gravatar

A gravatar is a globally recognized avatar (a graphic image or picture that represents a user). Typically a user's gravatar is associated with their email address, and using a service such as Gravatar.com, a blog owner to can configure their blog so that a user's gravatar is displayed along with their comments.



Hack

A hack is a bit of code written to customize or extend the functionality of a software product. Older versions of WordPress used a hack-based extension system, but versions 1.2 and above of WordPress use a plugin API with hooks for extensions.

Hacking

Hacking is the process of writing code for, or contributing code to, a piece of software.

There is some controversy surrounding the meaning of this term. It began as a benign term meaning "to exercise proficiency" or "to alter or improve," but the popular media have since construed it to mean "to break into a computer system, usually with malicious intent." Many in the computer industry have recently begun trying to 'take back' the word from its popular mutation, and many have adopted the term cracking to replace the malicious interpretation. Because of the desire to reclaim the word, you will often find the term used in conjunction with open source projects, intended in its benign form. For more information about the history of the term, please see Wikipedia's article on Hacker.

.htaccess

A .htaccess file is a granular configuration file for the Apache web server software, used to set or alter the server's configuration settings for the directory in which it is present, and/or its child directories.

WordPress uses an .htaccess file in conjunction with the mod_rewrite Apache module to produce permalinks.

Note that .htaccess is a hidden file in Unix/Linux (as dictated by the preceding period '.'), meaning it may not be visible using the default settings of some FTP clients.

HTML

HTML, ou Hypertext Markup Language, is the W3C standard language with which all web pages are built. It is the predecessor to XHTML, but HTML is often still used to describe either one. It is often used in conjunction with CSS and/or JavaScript.

WordPress strives to conform to the XHTML standard.

ISAPI

ISAPI (Internet Server Application Programming Interface) is a set of programming standards designed to allow programmers to quickly and easily develop efficient Web-based applications. Developed by Process Software and Microsoft Corporation, ISAPI is intended to replace CGI programs.

JavaScript

Developed by Netscape and Sun, JavaScript is a client-side programming or scripting language. It's used to create interactive and dymanic effects on a web page, as well as handle and manipulate form data. JavaScript is a separate language from Java. All modern browsers support JavaScript, with the exception of most text-based browsers (e.g., w3m). Some excellent JavaScript references and tutorials can be found at JavaScript Kit.

Link Permanente

A permalink is a URL at which a resource or article will be permanently stored. Many pages driven by Content Management Systems contain excerpts of content which is frequently rotated, making linking to bits of information within them a game of chance. Permalinks allow users to bookmark full articles at a URL they know will never change, and will always present the same content.

Permalinks are optional in WordPress, but are highly recommended as they greatly increase the cleanliness of URL. WordPress uses the Apache module mod_rewrite to implement its permalink system.

Linux

Linux is an open source computer operating system, created by Linus Torvalds, similar in style to Unix. It is popular in web server and other high-performance computing environments, and has recently begun to gain popularity in workstation environments as well.

Mac OS X

Mac OS X is an operating system specifically for modern Macintosh computers. The operating system was first commercially released in 2001. It consists of two main parts: Darwin, an open source Unix-like environment which is based on the BSD source tree and the Mach microkernel, adapted and further developed by Apple Computer with involvement from independent developers; and a proprietary GUI named Aqua, developed by Apple.

Meta

Meta has several meanings, but generally means information about. In WordPress, meta usually refers to administrative type information. As described in Meta Tags in WordPress, meta is the HTML tag used to describe and define a web page to the outside world (search engines). In the article Post Meta Data, meta refers to information associated with each post, such as the author's name and the date posted. Meta Rules define the general protocol to follow in using the Codex. Also, many WordPress based sites offer a Meta section, usually found in the sidebar, with links to login or register at that site. Finally, Meta is a MediaWiki namespace that refers to administrative functions within Codex.

Moblogging

Moblogging is the act of posting to one's blog via a mobile device, e.g. mobile phone, smartphone, or Blackberry. It is pronounced as mōbə-logging or mōb-logging, or sometimes as mŏb-logging in reference to smart mobs.

mod_rewrite

mod_rewrite is an extension module of the Apache web server software which allows for "rewriting" of URLs on-the-fly. Rewrite rules use regular expressions to parse the requested URL from the client, and translate it into a different URL before interpretation.

WordPress uses mod_rewrite for its permalink structure, which is optional functionality.

MySQL

MySQL is a popular open source SQL (Structured Query Language) database implementation, available for many platforms, including Windows, Unix/Linux and Mac OS X.

WordPress requires a MySQL database to store all blog information, including posts, comments, metadata, and other information.


Leitor de Novidades

A news aggregator or news (feed) reader is a computer program which tracks syndicated information feeds, via RSS, RDF, or Atom. Most news aggregators allow one to 'subscribe' to a feed, and automatically keep track of the articles one has read, similar to an email client tracking read emails.

Many blogs make their content available in feed form for the convenience of readers using news aggregators. WordPress can generate feeds in RSS and/or Atom formats.

Obsoleto

Obsoleto functions or template tags are no longer supported, and will soon be obsolete.

Página

A Page is often used to present "static" information about yourself or your site. A good example of a Page is information you would place on an About Page. A Page should not be confused with the time-oriented objects called posts. Pages are typically "timeless" in nature and live "outside" your blog.

The word "page" has long been used to describe any HTML document on the web. In WordPress, however, "Page" refers to a very specific feature first introduced in WordPress version 1.5.

Perl

Perl is an acronym for Practical Extraction and Report Language, but it's most commonly spelled as a proper name. It's a very popular and powerful scripting language used for web applications, although its use is being largely replaced by PHP in the mainstream. One of its strengths lies in its speedy and effective use of regular expressions. Its unofficial motto is, "There's More Than One Way To Do It," or "TMTOWTDI," owing to the extreme flexibility of the syntax.

WordPress does not use Perl, and it is therefore not required.

Permissões

Permissions are security settings restricting or allowing users to perform certain functions. In the case of files on Unix or Linux systems, there are three types of permissions: read, write, and execute. In the case of MySQL databases, there are many more: SELECT, INSERT, UPDATE, DELETE, etc. — although MySQL refers to them as privileges.

PHP

PHP is a recursive acronym for PHP: Hypertext Preprocessor. It is a popular server-side scripting language designed specifically for integration with HTML, and is used (often in conjunction with MySQL) in Content Management Systems and other web applications. It is available on many platforms, including Windows, Unix/Linux and Mac OS X, and is open source software.

WordPress is written using PHP and requires it for operation.

phpMyAdmin

phpMyAdmin is a popular, powerful web-based interface for administering MySQL databases. It is open source, written in PHP, and is among the better tools available for working with MySQL databases.

Ping

Within the WordPress interface, "ping" is sometimes used to refer to Pingbacks and Trackbacks.

In general computer terms, "ping" is a common utility used in a TCP/IP environment to determine if a given IP Address exists or is reachable. Typically, Ping is used to diagnose a network connection problem. Many times you will be asked, "Can you ping that address?". That means, does the Ping utility return a success message trying to reach the "problem" IP Address?

Pingback

Pingback lets you notify the author of an article if you link to his article (article on a blog, of course). If the links you include in an article you write on a blog lead to a blog which is pingback-enabled, then the author of that blog gets a notification in the form of a pingback that you linked to his article.

If you're feeling really geeky you may want to check out the Pingback technical specification or Otto's "How Pingbacks Work" explanation.

Plugin

A Plugin is a group of php functions that can extend the functionality present in a standard WordPress weblog. These functions may all be defined in one php file, or maybe spread among more than one file. Usually, a plugin is a php file that can be uploaded to the "wp-content/plugins" directory on your webserver, where you have installed WordPress. Once you have uploaded the plugin file, you should be able to "turn it on" or Enable it from the "Plugins" page in the administration interface of your weblog. The WordPress source code contains hooks that can be used by plugins.

Porta

Within the context of the WordPress community, a port is a bit of code that has been rewritten to be compatible with WordPress. For example, if someone wrote a plugin for MoveableType, WordPress users may want to find a port of that plugin for WordPress. Port can also be used as a verb: to rewrite a piece of software for a different platform/language.

Slug da Postagem

A word or two describing an entry, for use in permalinks (replaces the %posttitle% field therein), especially useful if titles tend to be long or they change frequently.

Status da Postagem

The status of a post, as set in the Administration Panel, Write Post SubPanel is either: Published (viewable by everyone), Draft (incomplete post viewable by anyone with proper user level), or Private (viewable only to WordPress users at Administrator level)

Provedor de Hospedagem

A hosting provider is a company or organization which provides, usually for a fee, infrastructure for making information accessible via the web. This involves the use of a web server (including web server software such as Apache), and may involve one or more related technologies, such as FTP, PHP, MySQL, and operating system software such as Linux or Unix.

Query string

A sequence of codes in a Uniform Resource Identifier (URI) that a web page uses to determine what dynamic data to display. The query string in a URI comes after an initial question mark, and may contain several parameters separated by ampersands. WordPress uses query strings to indicate criteria to search for specific posts or sets of posts in the database. The use of query strings is generally believed to impede the indexing of dynamic pages by search engines. For this reason, it is often desirable to use a method such as mod_rewrite to reduce exposure of query strings to search engines and other site visitors.

Query Variable

A Variable passed through the query string. For example, in the query string ?category_name=tech&feed=atom, there are two query variables: category_name with a value of 'tech', and feed with a value of 'atom'.

QuickTag

A Quicktag is a shortcut, or one-click button, that inserts HTML code into your posts. The <em> (emphasis) and </em> (stop emphasis) HTML tags are example of Quicktags. Some Quicktags, such as <!--contactform-->, insert HTML comment code that is used by plugins to replace text or perform certain actions.


Rascunho

The draft post status is for WordPress posts which are saved, but as yet unpublished. A draft post can only be edited through the Administration Panel, Write Post SubPanel by users of equal or greater User Level than the post's author.


RDF

Resource Description Framework. A language used to describe the locations of resources on the web. WordPress can produce output in RDF format that describes the locations of posts. Like RSS, RDF is used for content syndication.

Recordset

Recordset refers to the group of records or result returned from a database query.

Resumo

O Resumo is a condensed description of your blog postagem and refers to the summary entered in the Excerpt field of the Administration > Posts > Add New SubPanel. The excerpt is used to describe your post in RSS feeds and is typically used in displaying search results. The excerpt is sometimes used in displaying the Archives and Category views of your posts. Use the Template Tag the_excerpt() to display the contents of this field. Note that if you do not enter information into the Excerpt field when writing a post, and you use the_excerpt() in your theme template files, WordPress will automatically display the first 55 words of the post's content.

An excerpt should not be confused with the teaser, which refers to words before the <!--more--> in a post's content. When typing a long post you can insert the <!--more--> Quicktag after a few sentences to act as a cut-off point. When the post is displayed, the teaser, followed by a hyperlink (such as Read the rest of this entry...), is displayed. Your visitor can then click on that link to see the full version of your post. The Template Tag, the_content() should be used to display the teaser.

RSS

"Really Simple Syndication": a format for syndicating many types of content, including blog entries, torrent files, video clips on news-like sites; specifically frequently updated content on a Web site, and is also known as a type of "feed" or "aggregator". An RSS feed can contain a summary of content or the full text, and makes it easier for people to keep up to date with sites they like in an automated manner (much like e-mail).

The content of the feed can be read by using software called an RSS or Feed reader. Feed readers display hyperlinks, and include other metadata (information about information) that helps you decide whether they want to read more, follow a link, or move on.

The original intent of RSS is to make information come to you (via the feed reader) instead of you going out to look for it (via the Web).

Programs called news aggregators permit users to view many feeds at once, providing 'push' content constantly. See Category:Feeds for Codex resources about bringing RSS feeds into WordPress. See also RDF Site Summary.

Robots.txt

Web Robots are programs which traverse the Web automatically. They are also called Web Wanderers, Web Crawlers, and Spiders. Search Engines are the main Web Robots. Some Web Robots look for a file named robots.txt on your web server to see what and where they should look for content and files on your web server. Some Web Robots ignore this file.

Servidor Web

A web server is a computer containing software for, and connected to infrastructure for, hosting, or serving, web sites written in HTML. The most common web server software on the internet is Apache, which is frequently used in conjunction with PHP, Perl, and other scripting languages.

It is possible to create one's own web server, hosted on any speed of internet connection, but many people choose to purchase packages from hosting providers, who have the capacity and facilities to provide adequate bandwidth, uptime, hardware, and maintenance for frequently-visited web sites.


Shell

A shell is a program which interacts directly with an operating system such as MS-DOS, Unix/Linux, Mac OS X, or others — but it is most commonly associated with Unices. It is often referred to as a 'console' or 'command line', because it is controlled using typed commands rather than mouse or graphical interface input.

Most often, when interacting with a remote computer (as one would when configuring WordPress), an additional "faux" shell is involved called SSH.

Some popular shell programs are:

  • Bash (Bourne Again Shell)
  • Tcsh (an expanded C Shell)
  • Zsh

Shortcodes

São pequenos códigos simples que representam funções e códigos mais extensos, por exemplo, o shortcode [gallery] - nativo do WordPress - faz com que uma galeria de imagens seja mostrada em uma página ou post, na verdade este pequeno texto diz ao WordPress o que fazer para gerar a galeria sem que precisemos nos preocupar com programação.

Muitos plugins e temas oferecem shortcodes e estes podem permitir que se defina opções dentro deles, através de parâmetros.

Slug

A slug is a few words that describe a post or a page. Slugs are usually a URL friendly version of the post title (which has been automatically generated by WordPress), but a slug can be anything you like. Slugs are meant to be used with permalinks as they help describe what the content at the URL is.

Example post permalink: http://wordpress.org/development/2006/06/wordpress-203/

The slug for that post is "wordpress-203".


Spam

Once upon a time, SPAM was an animal by-product that came in a can and was fodder for many Monty Python sketches, but since the world-wide adoption of the internet as an integral part of daily life, Spam has become synonymous with what is wrong with the internet. Spam, in general terms, is an email or other forms of unsolicited advertising. Spam is very easy to spread throughout the internet, and works on the principle that if you send out thousands, or hundreds of thousands of unsolicited advertisements, scams, or other questionable methods of making money, that you only need a very small percentage of people to be fooled and you will make lots of money.

Common spam these days comes from online gambling sites and those trying to sell drugs for "male enhancement." Lately, web logs, or blogs, as we call them, have been targeted by spammers to try to increase their site ratings in the search engines. Spammers use various methods to distribute their electronic junk mail, and employ bots, or computer programs to quickly and easily send email or comments to millions of addresses and IPs all over the world.

Spammers can be difficult to track down as they often hijack peoples' email and IP addresses. When this happens, it may appear a friend sent you the spam, but in fact, the spammer's bot grabbed your friend's email address and used it to hide the true source of the spam. WordPress developers and community members are constantly working on more and better ways to combat these annoying spammers as they clog the internet with their garbage. You can help by offering your talents, ideas, suggestions, or just by being vigilant and installing any of the currently-available spam combating tools.

SSH

SSH stands for Secure Shell. It is a communication protocol for connecting to remote computers over TCP/IP. Various authentication methods can be used which make SSH more secure than Telnet.

SSL

SSL stands for Secure Sockets Layer and is the predecessor to Transport Layer Security. These are cryptographic protocols for secure communications across an unsecured network like the Internet.

Subversion

Subversion is an open-source version control software tool used by the WordPress Developers to maintain and track the changes and updates to the various WordPress versions.

Syndication

See RSS: Really Simple Syndication


Tag

A tag is a keyword which describes all or part of a Post. Think of it like a Category, but smaller in scope. A post may have several tags, many of which relate to it only peripherally. Like Categories, Tags are usually linked to a page which shows all posts having the same tag. Unlike Categories, Tags can be created on-the-fly, by simply typing them into the tag field.

Tags can also be displayed in "clouds" which show large numbers of Tags in various sizes, colors, etc. This allows for a sort of total perspective on the blog, allowing people to see the sort of things your blog is about most.

Many people confuse Tags and Categories, but the difference is easy: Categories generally don't change often, while your Tags usually change with every Post.

Tagline

A tagline is a catchy phrase that describes the character or the attributes of the blog in a brief, concise manner. Think of it as the slogan, or catchline for a weblog.

Task Based Documentation

Task based, or task oriented documentation is writing that takes you through a process/task step-by-step; it is succinct, lacks jargon, is easily understood, and structured entirely around performing specific tasks.

To order to get to Z, you need to:
  1. Step x
  2. Step y
  3. Step z


Keep in mind that people who need to know how to perform a task usually need answers quick!

Taxonomia

Uma Taxonomia permite a classificação de coisas. No WordPress, há dois tipos de taxonomias que são o uso de categorias e tags. Estas taxonomias ajudam a classificar os posts, páginas e tipos de posts.

Telnet

Telnet is a communications protocol used to establish a connection to another computer. Telnet runs on top of TCP/IP and is typically used in conjuction with terminal emulation software to login to remote computers. Telnet is inherently insecure and has largely been replaced by SSH


Tema

Um tema é uma coleção de arquivos que trabalha em conjunto para produzir uma interface gráfica com um desenho subjacente unificador para o weblog. Um tema modifica a forma como o weblog é exibida, sem modificar o software. Essencialmente, o sistema de temas WordPress é uma forma de skin para o weblog.

Tipo de Postagem

Post type refers to the various structured data that is maintained in the WordPress posts table. Native (or built-in) registered post types are post, page, attachment, revision, and nav-menu-item. Custom post types are also supported in WordPress and can be defined with register_post_type(). Custom post types allow users to easily create and manage such things as portfolios, projects, video libraries, podcasts, quotes, chats, and whatever a user or developer can imagine.

Trackback

Trackback helps you to notify another author that you wrote something related to what he had written on his blog, even if you don't have an explicit link to his article. This improves the chances of the other author sitting up and noticing that you gave him credit for something, or that you improved upon something he wrote, or something similar. With pingback and trackback, blogs are interconnected. Think of them as the equivalents of acknowledgements and references at the end of an academic paper, or a chapter in a textbook.

Twenty Ten theme

Starting with Version 3.0, the Twenty Ten theme became the default (and fallback) theme. As described in 2010: A Theme Odyssey, the Twenty Ten theme serves as a good example theme that includes new theme-based features, and looks nice on a public site. Twenty Ten is a community-developed theme.

Up to Version 2.9.2, the default theme was the Kubrick theme and was housed in the wp-content/themes/default folder. The Twenty Ten theme is housed in the wp-content/themes/twentyten folder and is the only theme in the WordPress distribution.



Unicode

A widely supported and preferred character encoding system.

For a computer to display letters (or any text characters), it needs to enumerate them - create an index of characters it knows how to display. These indexes are known as character sets. This is invaluable for users hosting WordPress in a non-English language.

The most widely used collections of these character sets are the iso-8859 with iso-8859-1 and iso-8859-15 (which contains the euro sign and some characters used in Dutch, French, Czech and Slovak) being the most common; they are also known as Latin1 and Latin9. These character sets use 8 bits (a single byte) for each character, allowing for 255 different characters (256, counting null). However, when considering that Latin-based languages aren't the only ones in the world (think Japanese or Hebrew), 255 characters aren't nearly enough.

There is a wide index of characters known as Unicode. Unicode has so many characters that sometimes more than 16 bits (2 bytes!) are required to represent them. Furthermore, the first 127 characters of Unicode are the same as the first 127 of the most widely used character set - iso-8859-1. For this purpose, UTF, the Unicode Translation Format, was created. UTF uses different numbers of bits for characters, and allows for the entire range of Unicode to be used. What you should probably know is:

  • UTF-8 is an 8-bit-minimum type of UTF. There are also UTF-16 and UTF-32.
  • If your document is in a Latin-based encoding, you probably don't need to change anything about it for it to be UTF.
  • A single UTF document can be in various languages with no need to switch encodings halfway through.

Unix

Unix, or UNIX, is a computer operating system developed at AT&T's Bell Laboratories starting back in 1969. Initially designed with the objective of creating an OS written in a high level language rather than assembly, a majority of web servers currently run on different "flavors" of this high-performance OS, or on Linux, developed as a Unix-like operating system.

Unix Time

Unix Time, or a timestamp, is a method of tracking time by determining the approximate number of seconds from a particular event. That event is called an Epoch. Since this time format is only off by a few seconds each century, it is usually considered good enough for most applications.

Unix time is (currently) a ten digit number, and looks like this like 1229362315. WordPress often uses a Unix timestamp internally to track time. The human readable times and dates you see are converted from Unix Time or from a MySQL DATETIME field.

URI Absoluta

A full URI.

 http://www.example.com/blog/images/icecream.jpg
 ftp://ftp.example.com/users/h/harriet/www/

URI Relativa

A relative URI (sometimes called a relative link) is a partial URI that is interpreted (resolved) relative to a base URI.

On the World Wide Web, relative URIs come in two forms:

A relative URI with an absolute path is interpreted relative to the domain root:

 /images/icecream.jpg → http://domain.example/images/icecream.jpg

A relative URI with a relative path is interpreted relative to the URL of the current document. E.g., on the web page http://domain.example/icecream/chocolate.html,

 strawberry.html → http://domain.example/icecream/strawberry.html

XFN

The XHTML Friends Network. A decentralised project to have inter-blog links that represent relationships between bloggers. XFN links resemble <a href="http://www.photomatt.net/" rel="friend met">Photo Matt</a>.

XHTML

XHTML, or Extensible HyperText Markup Language, is the successor to HTML as the W3C standard language with which all web pages are created. It is often used in conjunction with CSS and JavaScript.

WordPress strives to conform to the XHTML 1.0 Transitional standard.

XML

XML, or Extensible Markup Language, is written in Standard Generalized Markup Language (SGML) and essentially allows you to define your own markup language. XML is extremely useful in describing, sharing, and transmitting data across the Internet. Typically used in conjunction with HTML, XML defines data and HTML displays that data.

XML-RPC

XML-RPC is Extensible Markup Language-Remote Procedure Call. A Remote Procedure Call (RPC) allows you to call (or request) another application and expect that application to honor the request (answer the call). So, XML-RPC allows a user (or developer) to send a request, formatted in XML, to an external application.
