Discourse (software)
Discourse is an open source Internet forum system released on August 26, 2014. It was founded by Jeff Atwood, Robin Ward, and Sam Saffron. The client side application is written in EmberJS. The server side is written in Ruby on Rails and backed by a PostgreSQL database and Redis cache. The source code is distributed under the GNU General Public License version 2. Features Categorization Similar discussions can be organized under categories. Admins can create categories, add category descriptions and logos, and control access to topics in the category. Discourse provides granular control over read/write permissions. Discourse also supports sub-categorization or nested categories. Subcategories are categories in themselves so they can be controlled in the same manner as parent categories. The only difference is the parent-child relationship. Tagging Tags are a lightweight alternative to categories, but they can also be used in conjunction. Topics Conversations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby (programming Language)

Mention (blogging)
A mention (also known as @replies or tagging) is a means by which a blog post references or links to a user's profile. This may be done as a matter of getting the attention of (or drawing attention to) another user of a social networking or blogging service, as a matter of replying to the other user's post, or as a matter of "tagging" a user in a post. Styles and history @ (at sign) The rise to prominence of Twitter from its launch in 2006 gave rise to using the at sign ("@") as a description for directing a public post to a particular user, especially for the purpose of replying to another user's post (i.e., "@janedoe"). Only after the usage of @ as a visual means of directing posts to specific users gained currency among Twitter users did Twitter developers begin to integrate the @ sign as a fundamental conversational tool on the site. Initially, @ was used by Twitter users occasionally as shorthand for other words, such as location or time. The first person to use @ as a d ...

REST API
REST (Representational State Transfer) is a software architectural style that was created to describe the design and guide the development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of a distributed, Internet-scale hypermedia system, such as the Web, should behave. The REST architectural style emphasises uniform interfaces, independent deployment of components, the scalability of interactions between them, and creating a layered architecture to promote caching to reduce user-perceived latency, enforce security, and encapsulate legacy systems. REST has been employed throughout the software industry to create stateless, reliable, web-based applications. An application that adheres to the REST architectural constraints may be informally described as ''RESTful'', although this term is more commonly associated with the design of HTTP-based APIs and what are widely considered best practices regarding the "verbs" ( HTTP ...

Discourse Air Theme
Discourse is a generalization of the notion of a conversation to any form of communication. Discourse is a major topic in social theory, with work spanning fields such as sociology, anthropology, continental philosophy, and discourse analysis. Following work by Michel Foucault, these fields view discourse as a system of thought, knowledge, or communication that constructs our world experience. Since control of discourse amounts to control of how the world is perceived, social theory often studies discourse as a window into power. Within theoretical linguistics, discourse is understood more narrowly as linguistic information exchange and was one of the major motivations for the framework of dynamic semantics. In these expressions, denotations are equated with their ability to update a discourse context. Social theory In the humanities and social sciences, discourse describes a formal way of thinking that can be expressed through language. Discourse is a social boundary that defin ...

BBCode
BBCode ("Bulletin Board Code") is a lightweight markup language used to format messages in many Internet forum software. It was first introduced in 1998. The available "tags" of BBCode are usually indicated by square brackets ( and ">/code> and /code>) surrounding a keyword, and are parsed before being translated into HTML. Tags Implementation BBCode is typically implemented by applying a series of regular expression A regular expression (shortened as regex or regexp), sometimes referred to as rational expression, is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" ... string-replace operations upon the input. Because regular expressions are limited in analyzing the structure of text input, this has the artifact that any non-hierarchical BBCode input will be transformed into invalid non-hierarchical HTML without error. Applying traditional parsing techniques is made difficult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Just-in-time Learning
Just-in-time learning is an approach to individual or organizational learning and development that promotes need-related training be readily available exactly when and how it is needed by the learner. Methodology Just-in-time learning is different from structured training or scheduled professional development, both of which are generally available at set dates and times. What makes just-in-time learning unique is a strategy focused on meeting the learner's need when it arises, rather than pre-scheduled education sessions that occur regardless of the immediacy or scope of need. Therefore, planning for just-in-time learning requires anticipating what is needed by the various learners, when and where they may be when they experience the need, and the creation of content oriented toward meeting those needs in ways that are focused and accessible. The learning that is provided in a just-in-time format is often by short online videos, targeted elearning, printed and accessible job ai ...

OEmbed
oEmbed is an open format designed to allow embedding content from a website into another page. The specification was created by Cal Henderson, Leah Culver, Mike Malone, and Richard Crowley in 2008. It is used by companies like Twitter to make tweets embeddable in blog posts and by blogging platforms like Medium to allow content authors to include those snippets. An oEmbed exchange occurs between a consumer and a provider. A consumer wishes to show an embedded representation of a third-party resource on their own website, such as a photo or an embedded video. A provider implements the oEmbed API to allow consumers to fetch that representation. The following software is able to embed content from websites that support oEmbed: * Squarespace * WordPress * Drupal * LinkedIn * HumHub HumHub is a free and open-source social network A social network is a social structure consisting of a set of social actors (such as individuals or organizations), networks of Dyad (sociology), dyad ...

Social Graph
A social graph is a graph that represents social relations between entities. It is a model or representation of a social network. The social graph has been referred to as "the global mapping of everybody and how they're related". The term was used as early as 1964, albeit in the context of isoglosses. Leo Apostel uses the term in the context here in 1978. The concept was originally called sociogram. The term was popularized at the Facebook F8 conference on May 24, 2007, when it was used to explain how the newly introduced Facebook Platform would take advantage of the relationships between individuals to offer a richer online experience. The definition has been expanded to refer to a social graph of all Internet users. Since explaining the concept of the social graph, Mark Zuckerberg, one of the founders of Facebook, has often touted Facebook's goal of offering the website's social graph to other websites so that a user's relationships can be put to use on websites outsi ...

Drag And Drop
In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user (computing), user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what command is performed by the drag and drop, which can decrease usability. Actions The basic sequence involved in drag and drop is: * Move the pointer (computing WIMP), pointer to the object * Press, and hold down, the button on the computer mouse, mouse or other pointing device, to "grab" the object * "Drag" the object to the desired location by moving the pointer to this one * "Drop" the object by releasing th ...
