Libtorrent
libtorrent is an open-source implementation of the BitTorrent protocol. It is written in and has its main library interface in C++. Its most notable features are support for Mainline DHT, IPv6, HTTP seeds and μTorrent's peer exchange. libtorrent uses Boost, specifically Boost.Asio to gain its platform independence. It is known to build on Windows and most Unix-like operating systems (OS X, Linux, and many BSDs). libtorrent is kept up to date with bittorrent extensions that developers deem most useful, and is actively being optimized to work in a broader set of environments. Many of its features can be disabled at compile-time to not include code that would not be used in a particular use case. It aims to be the most suitable libtorrent implementation for embedded devices as well as desktops and seed-servers. Some of its implementation details are described in the features section. The original author of libtorrent is Arvid Norberg. It is the first client to support the ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnet URI Scheme
Magnet is a Uniform Resource Identifier, URI scheme that defines the format of magnet links, a de facto standard for identifying files (Uniform Resource Name, URN) by their content, via Cryptographic hash function, cryptographic hash value rather than by their location. Although magnet links can be used in a number of contexts, they are particularly useful in peer-to-peer file sharing networks because they allow resources to be referred to without the need for a continuously available host, and can be generated by anyone who already has the file, without the need for a central authority to issue them. This makes them popular for use as "guaranteed" search terms within the file sharing community where anyone can distribute a magnet link to ensure that the resource retrieved by that link is the one intended, regardless of how it is retrieved. History The standard for Magnet Uniform Resource Identifier, URIs was developed by Bitzi in 2002, partly as a "vendor- and project-neutral ...

Peer Exchange
Peer exchange or PEX is a communications protocol that augments the BitTorrent file sharing protocol. It allows a group of users (or peers) that are collaborating to share a given file to do so more swiftly and efficiently. In the original design of the BitTorrent file sharing protocol, peers (users) in a file sharing group (known as a "swarm") relied upon a central computer server called a tracker to find each other and to maintain the swarm. PEX greatly reduces the reliance of peers on a tracker by allowing each peer to directly update others in the swarm as to which peers are currently in the swarm. By reducing dependency on a centralized tracker, PEX increases the speed, efficiency, and robustness of the BitTorrent protocol. Description Users wishing to obtain a copy of a file typically first download a torrent file that describes the file(s) to be shared, as well as the URLs of one or more central computers called trackers that maintain a list of peers currently sharing the ...

Super-seeding
In file sharing, super-seeding (aka 'Initial Seeding') is an algorithm developed by John Hoffman for the BitTorrent communications protocol that helps downloaders become uploaders more quickly, but it introduces the danger of total seeding failure if there is only one downloader. The algorithm applies when there is only one seed in the swarm. By permitting each downloader to download only specific parts of the files listed in a torrent, it allows peers to start seeding more quickly. Peers attached to a seed with super-seeding enabled therefore distribute pieces of the torrent file much more readily before they have completed the download themselves. In 2003, BitTornado became the first BitTorrent client to implement the algorithm. Effects Testing by one group found that super seeding can help save an upload ratio of around 20%. It works best when the upload speed of the seed is greater than that of individual peers. Super seeding transfers stall when there is only one downloa ...

Local Peer Discovery
The Local Peer Discovery protocol, specified as BEP-14, is an extension to the BitTorrent file-distribution system. It is designed to support the discovery of local BitTorrent peers, aiming to minimize the traffic through the Internet service provider's (ISP) channel and maximize use of higher-bandwidth local area network (LAN). Local Peer Discovery is implemented with HTTP-like messages on User Datagram Protocol (UDP) multicast group 239.192.152.143:6771 ( IPv4) or ff15::efc0:988f (IPv6) which are administratively scoped multicast addresses. Since implementation is simple, Local Peer Discovery is implemented in several clients (μTorrent, BitTorrent/Mainline, MonoTorrent, libtorrent libtorrent is an open-source implementation of the BitTorrent protocol.

Miro (software)
Miro (formerly named Democracy Player or DTV) was an audio, video player and Internet television application developed by the Participatory Culture Foundation. It runs on Microsoft Windows, macOS, FreeBSD and Linux and supports most known video file formats. It offers both audio and video, some in HD quality. The Participatory Culture Foundation no longer develops Miro. The last version (6.0) was released in 2013 and is no longer functioning correctly because of changes to the YouTube API. Miro is free software, released under the terms of the GPL-2.0-or-later. Features Miro can automatically download videos from RSS-based "channels", manage them and play them. The application is designed to mesh with other Participatory Culture Foundation (PCF) products such as Video Bomb, a social tagging video website, and the Channel Channel, a TV guide for Internet television. Miro integrates an RSS news aggregator and podcatcher, a BitTorrent client (based on libtorrent), and a media pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LimeWire
LimeWire was a free software, free peer-to-peer file sharing client for Microsoft Windows, Windows, MacOS, Linux and Solaris OS, Solaris. Created by Mark Gorton in 2000, it was most prominently a tool used for the download and distribution of Online piracy, pirated materials, particularly Music piracy, pirated music. In 2007, LimeWire was estimated to be installed on over one-third of all computers globally. Both a freeware, zero-cost version and a purchasable "enhanced" version called LimeWire Pro were available; however, LimeWire Pro could be acquired for free through the standard LimeWire software, where users distributed it without authorization. LimeWire uses the gnutella network as well as the BitTorrent (protocol), BitTorrent protocol. BitTorrent support is provided by libtorrent (Rasterbar), libtorrent. On October 26, 2010, U.S. federal court judge Kimba Wood issued an injunction ordering Lime Wire LLC to prevent "the searching, downloading, uploading, file trading and ...

Deluge (software)
Deluge BitTorrent Client is a free and open-source, cross-platform BitTorrent client written in Python. Deluge uses a front and back end architecture where libtorrent, a software library written in C++ which provides the application's networking logic, is connected to one of various front ends including a text console, the web interface and a graphical desktop interface using GTK through the project's own Python bindings. Deluge is released under the terms of the GPL-3.0-or-later license. Features Deluge aims to be a lightweight, secure, and feature-rich client. To help achieve this, most of its features are part of plugin modules which were written by various developers. Starting with version 1.0, Deluge separated its core from its interface, running it instead in a daemon (server/service), allowing users to remotely manage the application over the web. Deluge has supported magnet links since version 1.1.0 released in January 2009. History Deluge was started by two m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micro Transport Protocol
Micro Transport Protocol or μTP (sometimes also uTP) is an open UDP-based variant of the BitTorrent peer-to-peer file sharing protocol intended to mitigate poor latency and other congestion control problems found in conventional BitTorrent over TCP, while providing reliable, ordered delivery. It was devised to automatically slow down the rate at which packets of data are transmitted between users of peer-to-peer file sharing torrents when it interferes with other applications. For example, the protocol should automatically allow the sharing of an DSL line between a BitTorrent application and a web browser. Development μTP emerged from research at Internet2 on QoS and high-performance bulk transport, was adapted for use as a background transport protocol by Plicto, founded by Stanislav Shalunov and Ben Teitelbaum and later acquired by BitTorrent, Inc. in 2006, and further developed within its new owner. It was first introduced in the μTorrent 1.8.x beta branches, and publ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
μTorrent
μTorrent, or uTorrent (see pronunciation) is a proprietary adware BitTorrent client owned and developed by Rainberry, Inc. with over 150 million users. It is the most widely used BitTorrent client outside China; globally only behind Xunlei. The " μ" (Greek letter " mu") in its name comes from the SI prefix "micro-", referring to the program's small memory footprint: the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet. μTorrent became controversial in 2015 when many users unknowingly accepted a default option during installation which also installed a cryptocurrency miner. The miner was removed in later versions, but had already done irreversible damage to μTorrent's reputation. The program has been in active development since its first release in 2005. Although originally developed by Ludvig Strigeus, since December 7, 2006, the code is owned and maintained by BitTorrent, In ...

Open Source
Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized software development model that encourages open collaboration. A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open-source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open-source appropriate technology, and open-source drug discovery. Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase ''open source'' became widely adopted, developers and producers have used a variety of other terms. ''Open source'' gained ...

Free Download Manager
Free Download Manager is a download manager for Windows, macOS, Linux and Android. Free Download Manager is proprietary software, but was free and open-source software between versions 2.5 and 3.9.7. Starting with version 3.0.852 (15 April 2010), the source code was made available in the project's Subversion repository instead of being included with the binary package. This continued until versions 3.9.7. The source code for version 5.0 and newer is not available and the GNU General Public License agreement has been removed from the app. The ability to download YouTube videos was included in the program's functionality until October 16th, 2021, when one of the developers, Alex, indicated that Google had filed a complaint report, requesting the option be disabled. Attempts to download any videos from YouTube currently result in the message, "Youtube downloads are not available" being shown in the download box. A resolution with Google's legal team still has yet to be reached. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Sheep
Electric Sheep is a volunteer computing project for animating and evolving fractal flames, which are in turn distributed to the networked computers, which display them as a screensaver. Process The process is transparent to the casual user, who can simply install the software as a screensaver. Alternatively, the user may become more involved with the project, manually creating a fractal flame file for upload to the server where it is rendered into a video file of the animated fractal flame. As the screensaver entertains the user, their computer is also used for rendering commercial projects, sales of which keep the servers and developers running. There are about 500,000 active users (monthly uniques). According to Mitchell Whitelaw in his ''Metacreation: Art and Artificial Life'', "On the screen they are luminous, twisting, elastic shapes, abstract tangles and loops of glowing filaments." The name "Electric Sheep" is taken from the title of Philip K. Dick's novel ''Do And ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
