µTorrent (or uTorrent and commonly abbreviated as "µT" or "uT") is a freeware Freeware is computer software that is available for use at no cost or for an optional fee. Software referred to as freeware is almost always proprietary. Software that is commercial is occasionally referred to as payware, closed source The term "proprietary software" is often used to mean computer software which is neither free nor open source . Terminology for forms of software licensing is not fully standardized and can be controversial. A literal meaning of "proprietary" in relation to software is that it has a copyright owner who can exercise control over BitTorrent BitTorrent is a peer-to-peer file sharing protocol used for distributing large amounts of data. BitTorrent is one of the most common protocols for transferring large files, and it has been estimated that it may account for as much as 43 % of all Internet traffic as of February 2009 client A BitTorrent client is a computer program that manages downloads and uploads using the BitTorrent protocol by BitTorrent, Inc. BitTorrent, Inc., headquartered in San Francisco, California, is an American company that develops peer-assisted Internet content delivery technology based on the BitTorrent protocol. The company was founded on September 22, 2004 by Bram Cohen and Ashwin Navin. BitTorrent, Inc. also maintains the BitTorrent protocol It is available for Microsoft Windows Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces . Microsoft Windows came to dominate the world's personal and Mac OS X Mac OS X is a series of Unix-based operating systems and graphical user interfaces developed, marketed, and sold by Apple Inc. Since 2002, Mac OS X has been included with all new Macintosh computer systems. It is the successor to Mac OS 9, the final release of the "classic" Mac OS, which had been Apple's primary operating system since 198. Both versions are written in C++.^[9] It gets the "µ Mu , Modern Greek Μι or Μυ [mi]) is the 12th letter of the Greek alphabet. In the system of Greek numerals it has a value of 40. Mu was derived from the Egyptian hieroglyphic symbol for water (𓈖) which had been simplified by the Phoenicians and named after their word for water, to become 𐤌. Letters that arose from Mu include the Roman M" in its name from the SI prefix The International System of Units specifies a set of unit prefixes known as SI prefixes or metric prefixes. An SI prefix is a name that precedes a basic unit of measure to indicate a decimal multiple or fraction of the unit. Each prefix has a unique symbol that is prepended to the unit symbol. The SI prefixes are standardized by the International "micro Micro is a prefix in the metric system denoting a factor of one millionth. Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning "small"" meaning one one-millionth and it refers to the program's small footprint This includes all sorts of active memory regions like code, static data sections , heap, as well as all the stacks, plus memory required to hold any additional data structures, such as symbol tables, constant tables, debugging structures, open files, etc, that the program ever needs while executing and will be loaded at least once during the by using the UPX UPX, the Ultimate Packer for eXecutables, is a free and open source executable packer supporting a number of file formats from different operating systems executable compressor. The program is designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze Azureus is a BitTorrent client used to transfer files via the BitTorrent protocol. Azureus is written in Java, and uses the Azureus Engine. In addition to torrenting, Azureus allows users to view, publish and share original DVD and HD quality video content. Content is presented through channels and categories containing TV shows, music videos, or BitComet BitComet is a cross-protocol BitTorrent, HTTP and FTP client written in C++ for Microsoft Windows and available in 52 different languages. Its first public release was version 0.28. The current BitComet logo has been used since version 0.50.

The program has received consistently good reviews for its feature set, performance, stability, and support for older hardware and versions of Windows. A report showed that µTorrent is the second most popular BitTorrent client (after the Chinese Xunlei Xunlei , is a download manager and bittorrent client developed by Xunlei corporation. Xunlei is the most commonly used BitTorrent client, due to its popularity in China).^[10]

The program has been in active development since its first release in 2005. Although originally developed by Ludvig Strigeus Ludvig Strigeus is a Swedish programmer best known for developing software such as the BitTorrent client µTorrent, OpenTTD, and ScummVM. He has a Master of Science in Computer Science and Engineering degree from Chalmers University of Technology and is currently employed as a software engineer at Spotify AB, since December 7, 2006 the code is owned and maintained by BitTorrent, Inc.^[11] The code has also been employed by BitTorrent, Inc. as the basis for version 6.0 of the BitTorrent client BitTorrent is a peer-to-peer program developed by Bram Cohen and BitTorrent, Inc. used for uploading and downloading files via the BitTorrent protocol. BitTorrent was the first client written for the protocol. It is often nicknamed Mainline by developers denoting its official origins. Since version 6.0 the BitTorrent client has been a rebranded, a re-branded version of µTorrent.

According to a study by Arbor Networks, the 2008 adoption of IPv6 Internet Protocol version 6 is an Internet Protocol version which is designed to succeed IPv4, the first implementation which is still in dominant use currently[update]. It is an Internet Layer protocol for packet-switched internetworks. The main driving force for the redesign of Internet Protocol is the foreseeable IPv4 address exhaustion. IPv6 by µTorrent caused a 15-fold increase in IPv6 traffic across the Internet over a ten-month period.^[12]

Features

Features present in µTorrent include:

• User configurable intelligent disk caching In computer science, a cache is a component that improves performance by transparently storing data such that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. If requested data is contained in the system.
• Full proxy server In computer networks, a proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to support.
• HTTPS tracker support.
• Configurable bandwidth In computer networking and computer science, bandwidth, digital bandwidth, or network bandwidth is a measure of available or consumed data communication resources expressed in bit/s or multiples of it scheduler.
• Localized In computing, internationalization and localization are means of adapting computer software to different languages and regional differences. Internationalization is the process of designing a software application so that it can be adapted to various languages and regions without engineering changes. Localization is the process of adapting for 52 languages.^[13]
• Initial seeding Super-seeding is a feature of some BitTorrent clients that attempts to minimize the amount of data which must be uploaded by the original seed until the first completion of a downloading peer. The feature was conceived by John Hoffman and first implemented in the BitTornado client in 2003. This feature is intended to be used when there is only one of torrents.
• Customizable search bar In a graphical user interface on a computer monitor a toolbar is a GUI widget on which onscreen buttons, icons, menus or other input or output elements are placed. Toolbars are seen in office suites, graphics editors and web browsers & user interface design.^[14]
• Configuration settings and temporary files are stored in a single directory, allowing portable use.
• WebUI In the industrial design field of human-machine interaction, the user interface is where interaction between humans and machines occurs. The goal of interaction between a human and a machine at the user interface is effective operation and control of the machine, and feedback from the machine which aids the operator in making operational decisions: A plugin In computing, a plug-in is a set of software components that adds specific capabilities to a larger software application. If supported, plug-ins enable customizing the functionality of an application. For example, plug-ins are commonly used in web browsers to play video, scan for viruses, and display new file types.

• Embedded Tracker A BitTorrent tracker is a server that assists in the communication between peers using the BitTorrent protocol. It is also, in the absence of extensions to the original protocol, the only major critical point, as clients are required to communicate with the tracker to initiate downloads. Clients that have already begun downloading also communicate: a simple tracker designed for seeding torrents, lacking a web interface or list of hosted torrents. It is not designed for secure or large-scale application.^[16]
• Quick-resumes interrupted transfers.
• Versions of µTorrent up to 1.8.5 build 17091^[17] can use as little as 14 MB of RAM running on a 486 The Intel i486 was the first tightly pipelined x86 design. Introduced in 1989, it was also the first x86 chip to use more than a million transistors, due to a large on-chip cache and an integrated floating point unit. It represents a fourth generation of binary compatible CPUs since the original 8086 of 1978, and it was the second 32-bit x86 processor on Windows 95 Windows 95 is a consumer-oriented graphical user interface-based operating system. It was released on August 24, 1995 by Microsoft, and was a significant progression from the company's previous Windows products. During development it was referred to as Windows 4.0 or by the internal codename Chicago.^[18] Unicode Unicode is a computing industry standard for the consistent representation and handling of text expressed in most of the world's writing systems. Developed in conjunction with the Universal Character Set standard and published in book form as The Unicode Standard, the latest version of Unicode consists of a repertoire of more than 107,000 support for Windows 95/98/ME, avoiding use of the Microsoft Layer for Unicode Microsoft Layer for Unicode is a software library for Windows software developers to simplify creating Unicode-aware applications for Windows 95, Windows 98, or Windows Me. It is also known as UnicoWS (Unicode for Windows 95/98/Me Systems) or UNICOWS.DLL, or even "cows" which is several times larger than µTorrent. Newer versions require Windows 2000 or newer.^[19]

Size

µTorrent is shipped as a single stand-alone compressed executable file, and does not require installation through an installer, which is available for trivial installation. Recent versions have included the ability to install themselves on first run. Small executable size is achieved by avoiding the use of many libraries, notably the C++ standard library and stream facilities, and creating substitutes written specifically for the program. The executable is then compressed to roughly half of its compiled and linked size using UPX.

History

Early development

Out of general discontent with bloatware, Serge Paquet suggested to Ludvig Strigeus that he should make a small and efficient BitTorrent client. Strigeus began to conceptualize the plans for the program's development, which, at the time, did not include making the client feature-rich. After initially working on it for about a month during the last quarter of 2004 (the first build is dated October 17, 2004), mostly during his free time before and after work, Strigeus ceased coding µTorrent for a year. He resumed work on September 15, 2005, and three days later, the first public release (version 1.1 beta) was made available as freeware, and began generating feedback.

Advertisements

In early versions, Strigeus had built in a web redirection via nanotorrent for search queries entered through the search bar that displayed advertisements in a frame on the web browser. Some users thought this suspicious because tracking could be implemented by recording the IP addresses of those downloading/receiving the advertisements, and the search functionality could easily be used to track user queries through whichever web-interface the client is going through to execute the search. After a short trial period, the advertising was disabled, mitigating possible concerns.^[20]

A later version of the software has, instead of ads, a "search all sites" feature, which is a keyword-based search bar that delivers listings of torrent files at different trackers. A frame at the top displays advertisements (server-side) in the browser when the search function is used. In version 1.5, no ads are present in the program itself.

As of build 463, a redirect bypass feature became available in the Advanced options.

PeerFactor SARL

On March 4, 2006, PeerFactor SARL announced the signing of a six-month contract with Strigeus for the development of "new content distribution applications on the Web."^[21] PeerFactor SARL is a relatively new company formed by former employees of PeerFactor, which was a subsidiary of the French anti-piracy organization Retspan.

Ludde stated that his coding for PeerFactor SARL was to use his expertise at optimization of the BitTorrent protocol to create a .dll which PeerFactor SARL intended to use as part of a distribution platform for files in a corporate setting.^[22] At the time there was some speculation that μTorrent may have been modified to spy on users on Peerfactor's behalf,^[21][23] however to date (even following μTorrent's acquisition by BitTorrent, Inc.) no evidence has been produced to support these allegations.

Ownership change

On December 7, 2006, µTorrent was purchased by BitTorrent, Inc., as it was announced on their official forum.^[11]

On September 18, 2007, BitTorrent 6.0 was released, which is a re-branded version of µTorrent. As a result, BitTorrent 6 is closed-source (unlike BitTorrent 5.x and before, which were open source software) and is currently only available for Windows.

Release history

Mac version

A separate version of µTorrent for Mac OS X 10.5 (commonly abbreviated as "µMac") has been in development for years.^[24] As of 28 June 2010; 32 days ago), a stable version (Intel x86 and PPC) is available for download on a separate section^[25] of the website.^[26]

Ask.com toolbar

As of version 1.8.2, the µTorrent installer gives the user the option to download and install the Ask.com toolbar. This is done on the first run of the program and the user may explicitly opt-out of this feature by deselecting it.^[27][28] The developers stated the addition was needed for funds to continue development.

Pronunciation

The author of µTorrent wrote in 2005, "I usually say 'you torrent' because it looks like a u", and offered "microtorrent", "mytorrent" (as "my" [myː] is the Swedish pronunciation of the Greek letter µ) and later "mutorrent" as candidate pronunciations.^[29] The symbol μ is the lowercase Greek letter Mu, and stands for the SI prefix "micro" meaning one one-millionth and refers to the program's small footprint.

About box easter eggs

• If the user opens the About screen ("Help" > "About µTorrent") and then presses the "T" key, it will start a built-in Tetris game called µTris.
• Clicking the µTorrent logo in the About screen will play a synthesized sound similar to Deep Note.

Contributors

Original development was performed by Ludvig Strigeus ("ludde", from Sweden), the creator of µTorrent. Serge Paquet ("vurlix", from Canada) acted as release coordinator, and had intended to work on Linux and Mac OS X ports. He maintained the µTorrent website and forum up until the end of 2005, but is no longer affiliated with µTorrent.

Development after the purchase by BitTorrent is performed by developers Greg Hazel ("alus"), Arvid Norberg ("arvid", author of libtorrent), Jan Brittenson ("CodeRed"), Richard Choi ("rchoi"), and Ryan Norton ("RyanNorton") at BitTorrent Inc. Strigeus remains as a technical consultant.

Other tasks continue to be performed by ongoing contributors. Giancarlo Martínez ("Firon", from Puerto Rico) maintains the µTorrent forums and FAQ. Carsten Niebuhr ("Directrix", from Germany) developed and maintains the µTorrent Web User Interface. Timothy Su ("ignorantcow", from Malaysia) is the designer of the current website.

Reception

μTorrent is praised for its small size and the minimal computer resources it uses which sets it apart from other clients. PC Magazine gave the program a positive review saying that it "packs an outstanding array of features".^[30] and was also listed in their Best free 157 software tools.^[31] It was also in PC World Magazine's 101 Fantastic freebies.^[32] The website TorrentFreak.com said it was the most feature rich BitTorrent client available,^[33] later summarizing an August 2009; 10 months ago) University of California, Riverside study^[34] which concluded that "uTorrent Download Speeds Beat Vuze By 16%" on average and "On 10% of [the 30 most used] ISPs, uTorrent users were downloading 30% faster than Vuze users".^[35] About.com said it was the best BitTorrent client available citing its small size and minimal impact to the rest of your computer's speed.^[36] Wired.com said its "memory footprint is also ridiculously small".^[37] The PC Authority magazine gave it a 6 out of 6 stars.^[38] Lifehacker.com has continued to rate it the best BitTorrent client available.^[39] CNET.com gave it a 5 out of 5 stars saying it features "Light and quick downloading".^[40]

In November 2009, 52 million users used the application.^[41]
