- “Open source as a development model promotes: a) Universal access via free license to a products design or blueprint, and b) universal redistribution of that design or blueprint, including subsequent improvements to it by anyone” (Gerber, Molefe, and van der Merwe 2010) In the past fifteen years, the principles ‘Open Source’ have exploded into the software industry. (Open Source Initiative 2012; Weber 2004) Open software now rivals the market share and quality of closed, commercial products. (Spinellis 2008) Following the success of open software, the same principles are being applied to other forms of product development.... [tags: software, digital era, architecture]

- The Advantages of Open Source Software "Open Source Software is primarily defined as software which is freely redistributable and includes the source code" (Varner, 1999). Open-source software may be seen as the opposite of proprietary software in which the end product is binary only. The idea of open source is not a new one. "The progress of science over half a millennium has been founded upon the notion of "open source"--a model in which the brightest minds contribute their work to the community for the betterment of humankind....

- Media and politicians have been discussing government shutdowns, spending cuts, and suspending entitlements in an effort to reduce the national debt. One approach politicians have been discussing is to raise the debt ceiling. Another approach is to reduce spending in all levels of the government. Politicians argue that without budget cuts, raising the debt ceiling will not solve the problem at hand. It will only force the government to face the same issue again in six months to a year. One area that should be discussed for budget cuts is the procurement, operations, and maintenance of the software that government employees use while carrying out their duties....

- Open Source Software vs. Microsoft Empire Introduction “I think that to try to own knowledge, to try to control whether people are allowed to use it, or to try to stop other people from sharing it, is sabotage. It is an activity that benefits the person that does it at the cost of impoverishing all of society. One person gains one dollars by destroying two dollars’ worth of wealth. I think a person with a conscience wouldn’t do that sort of thing except perhaps if he would otherwise die.” -- Richard Stallman Richard Stallman, the best-known figure of free software movement professes an absolute refusal of any notion of commercial software....

- INTRODUCTION TO OPEN-SOURCE Generally computer software sources (the human readable version of the software) are of two kinds; closed and open. Open-source programming has been prominently growing through the past ten years. In this model, programmers share their codes freely in order to be modified and used by others. They are allowed to alter and change the original software as much as they like. This in turn will produce higher quality software with improved features. For the open-source programs to be reliable, some sort of licenses has been approved by Open Source Initiative (OSI) which is a “non-profit corporation dedicated to managing and promoting the open-source definition for the...

- Open Source 2 Business Utilization of Open Source Software Open source software is used in many businesses and is used in more ways then people realize. The idea behind open source is the development of high quality, reliable and low-cost software. Some of the organizations using open source software include Travelocity, Wikipedia, and the US Postal Service. Some the widely used applications include Apache web service, Vyatta, 7zip and Open Office. Open system vs. closed system. Closed systems such as Microsoft products are the property of the company who developed and is protected under patents or copyright laws.... [tags: Business Technology]

- Open innovation is the use of purposive inflow and outflow of knowledge to accelerate internal innovation as well as to expand the markets for external use of innovation. The central idea behind open innovation is that in a world of widely distributed knowledge, companies cannot afford to rely entirely on their own research, but should instead use a mix of internal as well as external ideas. In addition, internal inventions not being used in a firm's business should be taken outside the company (e.g., through licensing, joint ventures, spin-offs)....

Both of these models have bugs that need fixing as well as application enhancements. Open source projects are quicker to become bug free (Martin). This is attributed to the openness of the source code of the application. If one can view and understand the source code, then one can better find the bugs in the application. These people may not necessarily be actively involved in the development efforts. Even though the source code is easily available to view, one may not be able to read code yet alone be able to comprehend it. Therefore, an open source support system is at work. This is one of the arguments about open source. The argument was that open source software has bad support, but this is not the case (Dickerson). One of these support systems is documentation. We see documentation in closed source software as well in the form of user manuals. But with the open source software the user gets the normal user guide plus extra benefits, such as the source code. Usually the documentation goes into the details of the program, so much so that normal users would get confused. But for advanced users, it could very well mean the difference of successfully getting something done or utterly failing. Along with the documentation, most projects will also have mailing lists. These mailing lists are used to convey important information pertaining to the application. People can subscribe to these mailing lists to get important information such as bug fixes, updates, and possibly future features that are being planned to be incorporated into the application. Open source projects also have public bug databases. These databases hold information of past and present bugs in the application for one to look up if he believes that he has found a bug.
Another advantage of open source software comes into play if a person has software engineers at her place of work. Software engineers have the ability to change how an open source application works or to add features to the application if the company requires it. Even if the company doesn’t have software engineers on board, there are always consultant companies to help. Some consultant companies have software engineers to help another company create a complete customized application for your companies use. And best of all, most of these consultant companies provide the source code, although most don’t advertise it.
There are two styles of software development. Eric Raymond’s definition is by far the simplest. One style of development is dubbed Cathedral Development. “This is the traditional style of development where teams are kept small. The design and functionality are well-understood before development begins. Complete plans from architecture, design, development, integration, and test are well-understood and documented. Release cycles during the development phase are few, and external feedback is only sought during alpha and beta test cycles (Fink 138).” The Cathedral style of software development is one that is known best. Microsoft uses the Cathedral style of software development. The other style of development is called Bazaar development. The Bazaar development definition is “A maintainer releases functionality that can be built and has some usefulness, but the package lacks functionality and defects may be prevalent. Release cycles are frequent (sometimes hourly). Feedback is sought as early and as frequently as possible. Anyone, anywhere, with a good idea can contribute to either fix defects or add interesting new functionality. The maintainer declares a production release when he or she determines it is ready (Fink 138).” The Cathedral development of software generates revenue by selling a license to use the software. One does not own the program yet alone receive the source code of the application; she is only allowed to use the program. Usually this license includes that one can only use it on one computer. One cannot use the same license on two or more computers simultaneously; therefore, this requirement forces the user to purchase additional licenses for the other computers which she wants to use the same software. The Bazaar development of software has a few different ways to generate revenue. One of these paths is through retail packaging. “Many customers are willing to pay for the simple convenience of media and manuals. Most are still unaware that they can simply download or copy the software legally and at no cost (Fink 178).” Another path that an open source company can take is through selling support for its products. “Distribution vendors typically bundle support services with their retail packages to help customers with installation and any other difficulties they may encounter. Large corporate customers will purchase comprehensive support services for their complex installations (Fink 178).” Allowing consumers to purchase subscriptions is also another possibility for an open source software company. “This is part of the services portfolio offered by some distribution vendors. Subscription services offer a number of options for keeping your software automatically up-to-date. Ximian Corporation uses subscription services to provide update services to user of the GNOME desktop (Fink 178).” A popular way which is used by Cathedral companies is to use brand associations. This tactic can also be used by Bazaar corporations. “Hardware and software vendors may work with distributions to associate them with their brand through bundling and other business activities. Depending on the situation, the vendor may charge for this association. The association usually imply some form of certification, which my by important to some customers (Fink 179).” Another revenue generating model is through aggregation and enhancing as Fink describes it. “A good example of this business model in action is a product from Covalent Technologies. The Apache Web Server is the most used Web server on the Internet (Fink 179).” Apache is a software application that allows a computer to ‘serve’ web pages to requestors. Covalent Technologies uses Apache as a base. Covalent then adds to this base with other software that they create. Some of the different concepts that Covalent integrates into Apache is manageability and security. With all of these different revenue generating paths, “open source software development is indeed a reliable model for conducting software development for commercial purposes (Open Sources 149).”
