Simple Update Protocol
Simple Update Protocol, or SUP, is a protocol developed by FriendFeed to simplify and speed up RSS and Atom feed updates. Updates from services that supported the protocol would appear on FriendFeed within seconds,Paul Buchheit''Simple Update Protocol: Fetch updates from feeds faster'' ''FriendFeed Blog'', August 27, 2008. until support was dropped. These sites include Disqus, Identi.ca, reddit. Functioning SUP introduces SUP feeds, which are lists of RSS and Atom feeds that have updated recently. A feed consumer (like FriendFeed, or a feedreader) can regularly poll a small number of SUP feeds instead of polling each individual feed. RSS and Atom feeds are identified in SUP feeds by an opaque, unique identifier derived from their URL. This allows a SUP feed to index private feeds without revealing their URL. SUP feeds are intended to be managed by services that publish large amounts of RSS and Atom feeds, though FriendFeed also hosted a public SUP feed which anyone could po ...

FriendFeed
FriendFeed was a real-time feed aggregator that consolidated updates from social media and social networking websites, social bookmarking websites, blogs and microblogging updates, as well as any type of RSS/Atom feed. It was created in 2007 by Bret Taylor, Jim Norris, Paul Buchheit and Sanjeev Singh. It was possible to use this stream of information to create customized feeds to share, as well as originate new posts-discussions, (and comment) with friends. Friendfeed was built on top of Tornado. The service was shut down at about 21:00 GMT on April 10, 2015, though the service blog announced it a month before. The goal of FriendFeed according to their website was to make content on the Web more relevant and useful by using existing social networks as a tool for discovering interesting information. Users could be an individual, business or organization. Bloggers writing about FriendFeed said that this service addresses the shortcomings of social media services which exclusively fa ...

Atom (standard)
The name Atom applies to a pair of related Web standards. The Atom Syndication Format is an XML language used for web feeds, while the Atom Publishing Protocol (AtomPub or APP) is a simple HTTP-based protocol for creating and updating web resources. Web feeds allow software programs to check for updates published on a website. To provide a web feed, the site owner may use specialized software (such as a content management system) that publishes a list (or "feed") of recent articles or content in a standardized, machine-readable format. The feed can then be downloaded by programs that use it, like websites that syndicate content from the feed, or by feed reader programs that allow internet users to subscribe to feeds and view their content. A feed contains entries, which may be headlines, full-text articles, excerpts, summaries or links to content on a website along with various metadata. The Atom format was developed as an alternative to RSS. Ben Trott, an advocate of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reddit
Reddit (; stylized in all lowercase as reddit) is an American social news aggregation, content rating, and discussion website. Registered users (commonly referred to as "Redditors") submit content to the site such as links, text posts, images, and videos, which are then voted up or down by other members. Posts are organized by subject into user-created boards called "communities" or "subreddits". Submissions with more upvotes appear towards the top of their subreddit and, if they receive enough upvotes, ultimately on the site's front page. Reddit administrators moderate the communities. Moderation is also conducted by community-specific moderators, who are not Reddit employees. As of March 2022, Reddit ranks as the 9th- most-visited website in the world and 6th most-visited website in the U.S., according to Semrush. About 42–49.3% of its user base comes from the United States, followed by the United Kingdom at 7.9–8.2% and Canada at 5.2–7.8%. Twenty-two percent of U.S. ...

Feedreader
In computing, a news aggregator, also termed a feed aggregator, feed reader, news reader, RSS reader or simply an aggregator, is client software or a web application that aggregates syndicated web content such as online newspapers, blogs, podcasts, and video blogs (vlogs) in one location for easy viewing. The updates distributed may include journal tables of contents, podcasts, videos, and news items. Function Visiting many separate websites frequently to find out if content on the site has been updated can take a long time. Aggregation technology helps to consolidate many websites into one page that can show only the new or updated information from many sites. Aggregators reduce the time and effort needed to regularly check websites for updates, creating a unique information space or ''personal newspaper''. Once subscribed to a feed, an aggregator is able to check for new content at user-determined intervals and retrieve the update. The content is sometimes described as bein ...

Polling (computer Science)
Polling, or polled operation, in computer science, refers to actively sampling the status of an external device by a client program as a synchronous activity. Polling is most often used in terms of input/output (), and is also referred to as polled or software-driven . A good example of hardware implementation is a watchdog timer. Description Polling is the process where the computer or controlling device waits for an external device to check for its readiness or state, often with low-level hardware. For example, when a printer is connected via a parallel port, the computer waits until the printer has received the next character. These processes can be as minute as only reading one bit. This is sometimes used synonymously with 'busy-wait' polling. In this situation, when an operation is required, the computer does nothing other than check the status of the device until it is ready, at which point the device is accessed. In other words, the computer waits until the device is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brightkite
Brightkite was a location-based social networking website. Users were able to "check in" at places by using text messaging or one of the mobile applications and they were able to see who is nearby and who has been there before. The service was created in 2007 by Brady Becker, Martin May, and Alan Seideman who previously founded the SMS notification service Loopnote. In April 2009 Brightkite was acquired by mobile social network Limbo. By December 2011, all Brightkite apps had been pulled from app stores and the Brightkite website was replaced with a message stating, "This is not goodbye...we're just moving on to something better". By April 2012, the Brightkite website no longer appeared to be in operation. Overview Brightkite allowed registered users to connect with their existing friends and also meet new people based on the places that they go. Once a user "checked in" at a place, they could post notes and photos to a location and other users could comment on those posts. Brigh ...

PubSubHubbub
WebSub (formerly PubSubHubbub) is an open protocol for distributed publish–subscribe communication on the Internet. Initially designed to extend the Atom (and RSS) protocols for data feeds, the protocol can be applied to any data type (e.g. HTML, text, pictures, audio, video) as long as it is accessible via HTTP. Its main purpose is to provide real-time notifications of changes, which improves upon the typical situation where a client periodically polls the feed server at some arbitrary interval. In this way, WebSub provides pushed HTTP notifications without requiring clients to spend resources on polling for changes. In October 2017, PubSubHubbub was renamed to WebSub for simplicity and clarity. , the WebSub protocol has been adopted by the W3C as a Recommendation. Protocol Under WebSub, there is an ecosystem of publishers, subscribers, and hubs. A subscriber first retrieves content from an HTTP resource ( URL) by requesting it from the webserver. The subscriber then inspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Protocols
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: ''protocols are to co ...
