A kiss (from Old English cyssan "to kiss", in turn from coss "a kiss", perhaps onomatopoeic) is the touching of the lips to some other thing, usually another person. Science of kissing is called Philematology.
Kissing is a learned behaviour, related to the grooming behaviour seen between other animals. Many non-human primates also exhibit kissing behaviour.
Kissing as affection
In modern Western culture, kissing is most commonly an expression of affection.
Between people of close acquaintance, a kiss, often reciprocal, is offered as a greeting or a good-bye. This kind of kiss is typically made by brief contact of puckered lips to the skin of the cheek or no contact at all, and merely performed in the air near the cheek with the cheeks touching. Such kissing is a common greeting in European and Latin American countries between a man and a woman or between two women. Relatives may kiss children to comfort them or show affection, and vice versa.
As an expression of romantic affection or sexual desire, kissing involves two people kissing one another on the lips, usually with much more intensity, and for a considerably longer period of time. In more passionate kissing couples may open their mouths, suck on each others' lips, or move their tongues into each others' mouths (see French kissing). Sexualized kissing may also involve one person kissing another on various parts of the body.
In romantic and sexual kissing, the physical sensations are often of primary importance.
Kissing as symbolismA symbolic kiss
When not an expression of affection, a kiss is a largely symbolic gesture in that the purpose of the kiss is to convey a meaning, such as salutations or subordination, rather than to experience the physical sensations associated with kissing. Kisses on the cheek as salutations are traditional in many parts of continental Europe, and the number of kisses, alternating cheeks, depends on which region one comes from.
Kissing may also be used to signify reverence and subordination, as in kissing the ring of a king or pope. A kiss can also be rude or done for the sake of irritating or proving one's superiority. A rude kiss or a kiss with a smack is referred to, in the USA, as a buss.
A more ominous use of the kiss is as a symbol of condemnation as may be observed when a crime lord kisses an underling, in effect imposing a sentence of death upon that person, the ultimate "goodbye kiss" or the "kiss of death."
The term Kissing Hands is used to formally describe the appointment of the senior state figures to office by British monarchs. Though in the past, the monarch's hand was actually kissed, this is no longer so. When figures such as the British Prime Minister, cabinet members and diplomatics are formally appointed, they are said to have Kissed Hands. (Kissing the hand is still practised as a romantic flourish, especially in Latin countries.)Man kissing boy

The term is also used for expressions of affection that do not involve the lips. The "Eskimo Kiss" is executed by the two individuals gently rubbing the tips of their noses together — in the Maori culture of New Zealand this is called a hongi. A "butterfly kiss" consists of two people putting their eyes close to each other and fluttering their eyelashes upon one another's.
A kiss can be "blown" using actions of the hand and the mouth. This is used to convey affection usually while parting, when the partners are physically distant but can view each other. Blown kisses are also used when a popular person wishes to convey affection to a large crowd or audience.
The kiss does not exist in all cultures, as certain societies find it repugnant.Young couple kiss in Minnesota, 1900
Asymmetry in kissing
In order to avoid clashing noses, a couple will often turn their faces to one side or another when kissing, so that their heads are at an angle from one another. Often, to make this more comfortable, one person, sitting upright, will support another, perhaps across their lap and in their arms, thus combining hugging and kissing. The person supporting the other is most likely taking the more active role in kissing the other. Writing in Nature, psychologist Oner Güntürkün observed couples kissing in public places such as airports and parks, and showed that the direction of turning is more frequently to the right than the left by a 2:1 ratio. Güntürkün ascribed this asymmetry to a neonatal right side preference.

The anatomy of kissing
Kissing is a complex behaviour that requires significant coordination. The most important muscle involved is the orbicularis oris muscle; it is used to pucker the lips and informally known as the kissing muscle. The tongue can also be an important part of the kiss.The Kiss by Gustav Klimt.

The tongue can also be an important part of the kiss. Companies, which offer a special business version of their distribution, add special support packages and special tools to administrate higher numbers of installations or do administrative tasks more easily. The most important muscle involved is the orbicularis oris muscle; it is used to pucker the lips and informally known as the kissing muscle. The business model of commercial suppliers is generally dependent on charging for support, especially for business users. Kissing is a complex behaviour that requires significant coordination. GNU/Linux users are often organised in so called Linux User Groups or abbreviated LUG. (data from Nature 421, 711 (13 February 2003); doi:10.1038/421711a). Technical support is provided by commercial suppliers and by other Linux users, usually in online forums, newsgroups and mailing lists.
Güntürkün ascribed this asymmetry to a neonatal right side preference. Complete distributions exist for most of these architectures, but most distributions focus on the "Intel" PC market. Writing in Nature, psychologist Oner Güntürkün observed couples kissing in public places such as airports and parks, and showed that the direction of turning is more frequently to the right than the left by a 2:1 ratio. But eventually, people started trying to port it to other platforms, and now Linux is available on many CPU architectures, among them:. The person supporting the other is most likely taking the more active role in kissing the other. As originally envisioned by Linus Torvalds, Linux was strictly an x86 application. Often, to make this more comfortable, one person, sitting upright, will support another, perhaps across their lap and in their arms, thus combining hugging and kissing. Linux also integrates well with Python, Perl, PHP and Ruby.
In order to avoid clashing noses, a couple will often turn their faces to one side or another when kissing, so that their heads are at an angle from one another. They are interpreted line-by-line as commands entered in the shell. The kiss does not exist in all cultures, as certain societies find it repugnant. These are applications that are written without the need for compilation of the code. Blown kisses are also used when a popular person wishes to convey affection to a large crowd or audience. Another option for linux programming is writing shell scripts. This is used to convey affection usually while parting, when the partners are physically distant but can view each other. Some of the most popular are Anjuta, Code::Blocks, KDevelop, NetBeans IDE, Glade (actually a user interface designer), Eclipse, the famous Emacs and Vim.
A kiss can be "blown" using actions of the hand and the mouth. There are also a number of IDEs available for Linux. A "butterfly kiss" consists of two people putting their eyes close to each other and fluttering their eyelashes upon one another's. GCC supports C, C++ and Java (for example by using GCJ) among other languages. The "Eskimo Kiss" is executed by the two individuals gently rubbing the tips of their noses together — in the Maori culture of New Zealand this is called a hongi. The GNU Compiler Collection (GCC) comes with the vast majority of distributions. The term is also used for expressions of affection that do not involve the lips. A number of compilers are available for Linux.
(Kissing the hand is still practised as a romantic flourish, especially in Latin countries.). In a corporate setting essentially the same can be done using a Citrix server, rdesktop to access a Microsoft Terminal Services server, or with NX technology. When figures such as the British Prime Minister, cabinet members and diplomatics are formally appointed, they are said to have Kissed Hands. At its simplest one or more people needing occasional access to Windows applications can share remote access to a single Windows PC for that purpose using VNC. Though in the past, the monarch's hand was actually kissed, this is no longer so. This is a good solution where applications are unable to be migrated, or an item of hardware such as a dongle, custom decoder card, or some USB devices will only run under Windows. The term Kissing Hands is used to formally describe the appointment of the senior state figures to office by British monarchs. A fourth alternative is to run the applications on a Windows machine but use remote access software such as VNC to view it on the Linux desktop.
A more ominous use of the kiss is as a symbol of condemnation as may be observed when a crime lord kisses an underling, in effect imposing a sentence of death upon that person, the ultimate "goodbye kiss" or the "kiss of death.". Aside from the performance difficulties, virtual machine approaches to running Windows applications cannot integrate Windows programs into the Linux desktop, as they must instead run inside the virtual Windows desktop. A rude kiss or a kiss with a smack is referred to, in the USA, as a buss. Full CPU emulators (such as QEMU or the slower counterpart Bochs) can be used, though to run a Windows program these emulators will also require a copy of Windows. A kiss can also be rude or done for the sake of irritating or proving one's superiority. VMware is a proprietary hardware virtualisation program that can run Windows in this way with near-perfect functionality, however this approach can carry a considerable speed and performance penalty. Kissing may also be used to signify reverence and subordination, as in kissing the ring of a king or pope. A third alternative for running Windows applications within Linux is to use a virtual machine program and run the desired application along with the entire virtual Windows operating system.
Kisses on the cheek as salutations are traditional in many parts of continental Europe, and the number of kisses, alternating cheeks, depends on which region one comes from. Since a legal copy of the Microsoft implementation of the Windows API is needed, use of Win4Lin requires a copy of Windows. When not an expression of affection, a kiss is a largely symbolic gesture in that the purpose of the kiss is to convey a meaning, such as salutations or subordination, rather than to experience the physical sensations associated with kissing. A similar alternative to running Windows applications inside Linux is to use the proprietary Win4Lin software, which converts Microsoft's version of the Windows API to run inside Linux rather than reimplementing it from scratch. In romantic and sexual kissing, the physical sensations are often of primary importance. Although compatibility is improving, in many cases week-by-week, applications that make use of non-standard programming practices can experience problems. Sexualized kissing may also involve one person kissing another on various parts of the body. Since these programs are written without use of any Microsoft code, they do not require a Windows license.
In more passionate kissing couples may open their mouths, suck on each others' lips, or move their tongues into each others' mouths (see French kissing). Many Windows programs run on Linux at approximately the same speed using these programs, and in some cases run even faster. As an expression of romantic affection or sexual desire, kissing involves two people kissing one another on the lips, usually with much more intensity, and for a considerably longer period of time. The popular Wine software, along with the commercial derivatives Crossover Office and Transgaming's Cedega create an application compatibility layer by reimplementing the Windows API inside of Linux. Relatives may kiss children to comfort them or show affection, and vice versa. There are several ways to run applications written for Microsoft Windows on Linux, with varying levels of success. Such kissing is a common greeting in European and Latin American countries between a man and a woman or between two women. Since nearly all settings are stored in ordinary text files they can be configured by any text editor.
This kind of kiss is typically made by brief contact of puckered lips to the skin of the cheek or no contact at all, and merely performed in the air near the cheek with the cheeks touching. There are also many command line utilities for configuring programs. Between people of close acquaintance, a kiss, often reciprocal, is offered as a greeting or a good-bye. Others, like Linuxconf, Gnome System Tools, and Webmin, are not distribution-specific. In modern Western culture, kissing is most commonly an expression of affection. The easiest way to do this is by using tools provided by distributions such as Debian's debconf, Mandriva's Control Center, or SUSE's YaST. . There are a number of ways to change these settings.
Many non-human primates also exhibit kissing behaviour. A few programs use a configuration database instead of files. Kissing is a learned behaviour, related to the grooming behaviour seen between other animals. Configuration of most system wide settings are stored in a single directory called
It lasted 30 hours and 45 minutes. MEPIS also runs from CD like Knoppix, and both can be installed onto a PC like any other Linux distribution. The longest recorded kiss took place in Tel Aviv, Israel, on April 5, 1999, between Karmit Tsubera and Dror Orpaz. The approach by Knoppix, which runs Linux directly from a CD without disturbing the PC's hard drive, is probably the most successful demonstration tool to date. In Lady and the Tramp, while Lady and Tramp were both eating the end of a noodle at the same time, their lips end up touching. Many commercial distributions are hard to install, but with work, allow someone to re-use an old machine to see what the Linux desktop is like. Auguste Rodin created the sculpture The Kiss (Le Baiser). Commercial exhibitions provide Linux demonstrations to potential new users, especially corporate buyers.
The Australian cover version is even titled Kiss Kiss. Linux User Groups, or LUGs, still provide the primary face-to-face forum for demonstration of Linux. The Turkish 1997 hit song Simarik has a chorus that ends with two kiss sounds. So-called "live CDs" that simply boot from CD and automatically load the necessary drivers for the user's respective system promise to change that. Gustav Klimt painted a work entitled The Kiss. The difficulty in quickly demonstrating Linux on the computer of a potential new user remains still an obstacle, slowing its adoption as a personal computing platform. In the Frog Prince fairytale, it is the male who is transformed from frog to man by a romantic kiss. After everything is done, the virtual machine can be booted just as if it were an independent computer.
The Matrix turns the tables on this motif when Trinity kisses the sleeping main character Neo, bringing him back to life at the end of the movie. The virtual machine software will simulate an isolated environment onto which the Linux system is installed. In the fairytale Sleeping Beauty and the Greek myth of Pygmalion and Galatea, a romantic kiss is used by a male to awaken or breathe life into a female, which feminist critics have interpreted as symbolising the suspect idea that women don't have much of a life unless their sexuality is awakened through the attention of men. Technology of virtual machines (such as Virtual PC or VMware) also enables Linux to be run inside another OS such as Microsoft Windows. The last words of British naval commander Horatio, Lord Nelson, are said to have been 'Kiss me Hardy!' to one of his subordinates. Similar approaches include coLinux. In the gospels, Judas betrayed Jesus with a kiss — a subversive use of the kiss, as it is a symbol of affection. A Linux boot loader will boot the Linux system when the PC is restarted and the user chooses to boot Linux.
The difference is that it is not necessary for the user to leave Windows, since Linux is installed to the Windows hard-disk partition. The software provides all the needed features; it is a real Linux distribution. After downloading the installer (more than 100MB), the user can install Linux just like any other Windows application. Consider WinLinux, for example.
Some let the user install Linux on top of their current system. Some beginners (especially those familiar with Microsoft Windows and Mac OS) may still feel that making the shift can be hard but many solutions have been created to solve this problem. Many distribution companies now are sparing no effort to provide users with advanced, easy and specific installations. It is famous for its ability to automatically partition a hard drive using the Disk Druid utility.
Anaconda, one of the more popular installers, is used by Red Hat Linux, Fedora Core and other distributions to simplify the installation process. Many distributions also support booting over a network, so an installation on a properly configured machine can be done remotely. The cost savings achieved by using thin clients can be invested in greater computing power or storage on the server. Variations on this mode include using local drives and computing power to run applications.
The clients can be ordinary PCs with the addition of the network bootloader on a drive or network interface controller. A Linux Terminal Server is a single machine to which many clients can connect this way, so one obtains the benefit of installing Linux on many machines for the cost of installing on one. Clients can boot over the network from the server and display results and pass information to the server where all the applications run. Still another mode of installation of Linux is to install on a powerful computer to use as a server and to use ordinary less powerful machines (perhaps without hard drives, and having less memory and slower CPUs) as thin clients over the network.
Similarly, some minimal distributions, such as tomsrtbt, can be run directly from as little as 1 floppy disk without needing to change the hard drive contents. With this, one boots from the CD and can use Linux without making any modification to the contents of the hard drive. Other distributions, such as Knoppix, can be run directly from a "live CD" running entirely in RAM, rather than installing it to the hard drive. After a basic system is installed, more software can be added by downloading it from the Internet or using CDs.
Some distributions, such as Debian, can be installed from a small set of floppy disks. Such a CD can be burned from a downloaded ISO image, purchased alone for a low price, or can be obtained as part of a box set that may also include manuals and additional commercial software. The most common method of installing Linux, supported by all major distributions, is by booting from a CD that contains the installation program and installable software. Further, personal computers that come with Linux distributions already installed are readily available from numerous vendors, including large mainstream vendors like Hewlett-Packard and Dell.
Also it is not normally necessary to feed a stack of driver CDs into a Linux installation as most hardware is supported out of the box. It is unnecessary to file license numbers and enter them during installation. Many distributions are at least as easy to install as a comparable version of Windows. In the past, difficulty of installation was a barrier to wide adoption of Linux-based systems, but the process has been made easy in recent years.
The paper Why Open Source Software / Free Software (OSS/FS)? Look at the Numbers! identifies many quantitative studies of open source software, on topics including market share and reliability, with many studies specifically examining Linux. The large number of choices of Linux distributions can also confuse users and software vendors. However, some observers claim that the intervals between Linux distribution releases are no worse, and often better, than the project management "schedule slipping" that occurs with other operating systems and with software systems in general. Linux distributions have been criticized for unpredictable development schedules, thus making enterprise users less comfortable with Linux than they might be with other systems (Marcinkowski, 2003).
However, Relevantive, the renowned Berlin-based organization specializing in providing consultation to companies on the usability of software and Web services, concluded that the usability of Linux for a set of desktop-related tasks is "equal to Windows XP." Since then, there have been numerous independent studies and articles    that show that a modern Linux desktop using Gnome or KDE is on par with or superior to Microsoft Windows. Microsoft-sponsored studies such as those by IDC and Gartner have argued that Linux had a higher total cost of ownership (TCO) than Windows. There have been conflicting studies of Linux's usability and cost in the past. Deliberately non-portable hardware drivers like Winmodems and Winprinters have been a general problem.
Often, this development requires reverse engineering of some sort, as certain manufacturers remain secretive and refuse to provide the hardware or firmware specifications for their products. Though some vendors provide device drivers, many device drivers must be developed by volunteers after the release of the product. Support for certain new and obscure hardware remains an issue. Linux is rapidly gaining popularity as a desktop operating system as it is increasingly used in schools and workplaces and more people are becoming familiar with it.
Linux is past that stage now, with numerous manufacturers installing Linux and many organizations having five or more years experience with Linux - since installation evolved to graphical user interfaces - or Unix, which has been around for decades. Because of reluctance to change and the fact that many computers still come with Microsoft Windows pre-installed, there has been a slow initial adoption of new desktop operating systems. Most distributions of Linux have two or more means of software installation, and more office and end-user applications now come with an automated installation program. However, general applications like spreadsheets, word processors, and browsers are available for Linux in profusion.
Equivalents of some specific programs may not be available. Users might have to switch application software, and there may be fewer options, as in the case of computer games. For example, Gentoo Linux, a source-based distribution, is time-consuming to install, but can be more usable for advanced users than stereotypical beginner-friendly distributions, such as Mandriva or Ubuntu. It is worth noting that an operating system's usability is subjective and dependent on the background knowledge and needs of its users.
It used to be easier to find local technical support for Windows or Mac OS than for Linux in some places but with local Linux User Groups or LUGs appearing everywhere this has changed. Many older programs with text user interfaces (TUI) have wild inconsistencies between them, but they maintain loyal followings. On the command shell, many usability hangups from early Unix days generally remain, such as the difficulty in finding some commands, and the inability to undo many operations such as file deletion. GUI configuration tools and control panels are available for many system settings and services, but editing of plain-text configuration files is often required.
The area of hardware and services configuration is where user experience is most varied. Additionally, proprietary software for other operating systems may be run through compatibility layers, such as Wine. A growing number of proprietary software vendors are supporting Linux, and open source development for Linux is also steadily increasing. While some very specific application may not be available for Linux, there usually exists a replacement, often of better quality.
Applications running within graphical desktop environments such as GNOME and KDE in Linux are very similar to those running on other operating systems. Linux and other free software projects have been frequently criticized for not going far enough in terms of ensuring usability, and Linux was once considered more difficult to use than Windows or the Macintosh, although this has changed. The Linux market is among the fastest growing and is projected to exceed $35.7 billion by 2008 (this statistic is not comparable to capitalised operating systems like Windows - since Linux is free to use). However, argued advantages of Linux, such as lower cost, fewer security vulnerabilities  , and lack of vendor lock-in, have spurred a growing number of high-profile cases of mass adoption of Linux by corporations and governments.
According to market research company IDC, in 2002, only 25% of servers and 2.8% of desktop computers were already running Linux. Its market share of desktops is rapidly growing. Once viewed as an operating system only computer professionals and aficionados could use, Linux distributions have become user-friendly, with many graphical interfaces and applications. Graphical Linux software exists for almost any area and in some areas there is a greater quality and quantity of software available than for proprietary operating systems.
In desktop environments like GNOME and KDE, Linux may be used with a user interface that is similar to that of Mac OS, Microsoft Windows, or other desktop environments, and its traditional Unix-like command line interface. Linux is rapidly gaining popularity as a desktop operating system. As of June 2005, the 3 fastest supercomputers in the world (as recorded by the Top500) run Linux. Linux is increasingly common as an operating system for supercomputers, most recently on 64-bit AMD Opterons in the Cray XD1.
Linux is also expanding into telecommunications equipment through efforts such as Carrier Grade Linux. The TomTom satellite navigation system also uses an embedded version of the Linux kernel. A large number of network firewalls and routers, including several from Linksys and Netgear, use Linux internally, taking advantage of its advanced firewalling and routing capabilities. The popular TiVo digital video recorder also uses a customized version of Linux.
In handheld devices, it is an increasingly popular alternative to the Windows CE and Palm OS operating systems. In mobile phones, Linux has become a major competitor to the proprietory Symbian OS software. Its low cost makes it particularly useful in set-top boxes and for devices such as the Simputer, a computer aimed mainly at low-income populations in developing nations. Linux is also often used in embedded systems.
Sony has previously released a PS2 Linux kit for their PlayStation 2 video game console. The multi-billion dollar video game industry will see widespread Linux use with the 2006 launch of the Sony PlayStation 3 video game console which will run Linux out of the box. Additionally, Linux has a plethora of database software such as MySQL, Sybase ASE (linux application) , mSQL and others. A prominent example of this software combination in use is MediaWiki — the software primarily written for Wikipedia.
Linux is the cornerstone of the so-called LAMP server-software combination (Linux, Apache, MySQL, Perl/PHP/Python) that has achieved widespread popularity among Web developers, making it one of the most common platforms on the Web. Linux has made considerable gains in server and special-purpose markets, such as image rendering and Web services, and is now making inroads into the high volume desktop market. This stereotype has been dispelled in recent years by the increased user-friendliness and broad adoption of many Linux distributions. Because of this, and because of being attracted by access to the internals of the system, Linux users have traditionally tended to be more technologically oriented than users of Microsoft Windows and Mac OS, sometimes revelling in the tag of "hacker" or "geek".
In the past, a user needed significant knowledge of computers in order to install and configure Linux. The source code for the Linux kernel used to be maintained using the software application called BitKeeper but, partly because a license dispute, it is now maintained via Git, the new directory content manager created by Linus Torvalds himself. This distribution contained over fifty-five million source lines of code, and the study estimated that it would have cost 1.9 billion dollars (year 2000 dollars) to develop by conventional proprietary means. In a later study, Counting potatoes: the size of Debian 2.2, the same analysis was performed for Debian GNU/Linux version 2.2.
Slightly over half of the code in that distribution was licensed under the GPL. Had all this software been developed by conventional proprietary means, it would have cost 1.08 billion dollars (year 2000 dollars) to develop in the United States. Using the Constructive Cost Model (COCOMO), the study estimated that this distribution required about eight thousand person-years of development time. The Linux kernel contained 2.4 million lines of code, or 8% of the total.
More Than a Gigabuck: Estimating GNU/Linux's Size, a study of Red Hat Linux 7.1, found that this particular distribution contained 30 million source lines of code (SLOC). A variety of Linux distribution screenshots can be viewed here. A typical general-purpose distribution includes the Linux kernel, some GNU libraries and tools, command-line shells, and thousands of application software packages, from office suites and the graphical X Window System to compilers, text editors, and scientific tools. Over 450 distributions are available .
Distributions are created for many different purposes, including localization, architecture support, real-time applications, and embedded systems, and many deliberately include only free software. They include additional system software and application programs, as well as certain processes to install these systems on a computer. These are compiled by individuals, loose-knit teams, and various professional organizations. Linux is predominantly used as part of a Linux distribution (commonly called a 'distro').
The most comprehensive coverage of this suit is given by Groklaw. A few of Novell's press releases seem to demonstrate serious problems with SCO's claims:. To date, no proof of SCO's claims of copied code in Linux has been provided and SCO's claims have varied widely. This controversy has involved lawsuits by SCO against Novell, DaimlerChrysler (partially dismissed in July, 2004), and AutoZone, and by Red Hat and others against SCO.
Additionally, SCO sent letters to a number of companies warning that their use of Linux without a license from SCO may be actionable, and claimed in the press that they would be suing individual Linux users. In March 2003, the SCO Group (SCO) filed a lawsuit against IBM claiming that IBM had contributed some portions of SCO's copyrighted code to the Linux kernel in violation of IBM's license to use Unix. The distinction between Torvalds' kernel and entire Linux-based systems that contain the kernel is a perennial source of confusion, and the naming remains controversial. Torvalds, the creator of the Linux kernel, has said that he finds calling Linux in general GNU/Linux "just ridiculous." Still, some distributions do use this name — notably Debian GNU/Linux — while most people simply refer to the system as Linux.
Because the GNU libraries and programs, an essential part of nearly all Linux distributions, stem from a long-standing free operating system project that predates the Linux kernel, Richard Stallman and the Free Software Foundation ask that the combined system (regardless of distribution) be referred to as GNU/Linux or a Linux-based GNU system. See also List of words of disputed pronunciation for a fuller technical discussion of the various ways "Linux" is pronounced. Note that in English, "Linux" and "Minix" are usually pronounced with a short /ɪ/ sound that is different from Torvalds's phonemically Finland-Swedish pronunciation of these words (which is somewhere between what would be considered short and long in English). An audio file of Torvalds saying "Hello, this is Linus Torvalds, and I pronounce Linux as /lɪnʊks/" also exists .
In 1992, Torvalds explained  (IPA pronunciations added to quote in braces):. Other variations are also possible, but less frequently heard. The first pronunciation is considered more correct, while the second has become popular for sounding more natural in English. Linux is most commonly pronounced either to rhyme with minix [ˈlɪnəks], or to sound like lie nix [ˈlaɪnəks].
In September 2005, Intellectual Property Australia, the trademark regulator in Australia, rejected an application to trademark Linux. LMI has also sought to enforce the Linux trademark in countries other than the US. Reg No: 1916230) is owned by Linus Torvalds, registered for "Computer operating system software to facilitate computer use and operation." The licensing of the trademark is now handled by the Linux Mark Institute (LMI). The Linux trademark (U.S.
In 1997, Linus Torvalds stated, "Making Linux GPL'd was definitely the best thing I ever did."  Other subsystems use other licenses, although all of them share the property of being free/open-source; for example, several libraries use the LGPL (a more-permissive variant of the GPL), and the X Window System uses the permissive (non-copyleft) MIT License. The GPL requires that all source code modifications and derived works also be licensed under the GPL, and is sometimes referred to as a "share and share-alike" (or copyleft) license. The Linux kernel, along with most of the GNU components, is licensed under the GNU General Public License (GPL) version 2 (not or later). Originally, Linus was going to call it Freax for "free" and with the often-used X in the names of Unix-like systems.
(The name Linux was derived from Linus' Minix.) The name was later trademarked (see below). He was the one to invent the name Linux for the directory from which Torvalds' project was first available for download . Lemmke was working for the Helsinki University of Technology (TKK), located in Espoo near Helsinki, as an administrator of ftp.funet.fi, an FTP server which belongs to the Finnish University and Research Network (FUNET), which has numerous organizations as its members, amongst them the TKK and the University of Helsinki. The name "Linux" was coined, not by Torvalds, but by Ari Lemmke.
Tux the penguin is the logo and mascot of Linux (although there are other, less common representations,such as theOS-tan), based on an image created by Larry Ewing in 1996. The task of producing an integrated system, which combines all of these basic components along with graphical interfaces (such as GNOME or KDE, which in turn are based on the X Window System) and application software, is now performed by Linux distribution vendors / organizations. Today, Torvalds continues to direct the development of the kernel, while other subsystems such as the GNU components are developed separately. The Linux system quickly surpassed Minix in functionality; Torvalds and other early Linux kernel developers adapted their kernel to work with the GNU components and user-space programs to create a complete, fully functional, free operating system.
Initial versions of Linux also required an operating system to be present in order to boot from a hard disk, but soon there were independent bootloaders, the most well known being lilo. A computer running Minix was originally necessary in order to configure, compile, and install Linux. By the 0.01 release, Linus had implemented enough POSIX system calls to make Linux run the GNU Bash shell; after this bootstrapping procedure, development accelerated rapidly. Raymond's essay The Cathedral and the Bazaar discusses the development model of the Linux kernel and similar software.
Eric S. Since then, thousands of developers from around the world have participated in the project. The first version of the Linux kernel (0.01) was released to the Internet on September 17, 1991, with the second version following shortly thereafter in October . After that, it gradually evolved into an entire operating system kernel intended as a foundation for POSIX-compliant systems.
When Linus needed to read and write files to disk, this task-switching terminal emulator was extended with an entire filesystem handler. The terminal emulator was running two threads: one for sending and one for receiving characters from the serial port. Linux started out as a terminal emulator written in IA-32 assembler and C, which was compiled into binary form and booted from a floppy disk so that it would run outside of any operating system. However, Tanenbaum did not permit others to extend his operating system, leading Torvalds to develop a replacement for Minix.
Torvalds originally used Minix, a simplified Unix-like system written by Andrew Tanenbaum for teaching operating system design. Meanwhile, in 1991, another kernel — eventually dubbed "Linux" — was begun as a hobby by Finnish university student Linus Torvalds while attending the University of Helsinki. However, due to a lack of cooperation from the Berkeley programmers, Stallman decided instead to use the Mach microkernel, which subsequently proved unexpectedly difficult, and the Hurd's development proceeded slowly. According to Thomas Bushnell, the initial Hurd architect, their early plan was to adapt the BSD 4.4-Lite kernel and, in hindsight, "It is now perfectly obvious to me that this would have succeeded splendidly and the world would be a very different place today" .
The GNU project began developing their own kernel, the Hurd, in 1990 (after an abandoned attempt called Trix). By the beginning of the 1990s, GNU had produced or collected nearly all of the necessary components of this system—libraries, compilers, text editors, a Unix-like shell, and other software—except for the lowest level, the kernel. The goal of GNU was to develop a complete Unix-like operating system composed entirely of free software. In 1983, Richard Stallman founded the GNU project, which today provides an essential part of most Linux systems (see also GNU/Linux, below).
. It is deployed in applications ranging from embedded systems (such as mobile phones and personal video recorders) to personal computers to supercomputers. Linux was originally developed for Intel 386 microprocessors and now supports all popular computer architectures (and several obscure ones). Proponents and analysts attribute this success to its vendor independence (the opposite of vendor lock-in), low cost, security, and reliability.
Since then, Linux has gained the support of major corporations such as IBM, Sun Microsystems, Hewlett-Packard, and Novell for use in servers and is gaining popularity in the desktop market. Initially, Linux was primarily developed and used by individual enthusiasts. Most broadly, a Linux distribution bundles large quantities of application software with the core system, and provides more user-friendly installation and upgrades. In the narrowest sense, the term Linux refers to the Linux kernel, but it is commonly used to describe entire Unix-like operating systems (also known as GNU/Linux) that are based on the Linux kernel combined with libraries and tools from the GNU Project and other sources.
It is one of the most prominent examples of free software and of open-source development: unlike proprietary operating systems such as Windows and Mac OS, all of its underlying source code is available to the public for anyone to freely use, modify, improve, and redistribute. Linux is a computer operating system and its kernel. Greene, The Register, retrieved December 22, 2005. Mandrake 8.1 easier than Win-XP by Thomas C.
