Open source software development

Open source software development is the process by which open source software (or similar software whose source code is publicly available) is developed. These are software products “available with its source code and under an open source license to study, change, and improve its design”. Examples of popular open source software products are Mozilla Firefox, Google Chrome, Android and the OpenOffice.org Suite. In the past, the open source software development method has been very unstructured, because no clear development tools, phases, etc., had been defined like with development methods such as Dynamic Systems Development Method. Instead, every project had its own phases. However, more recently there has been much better progress, coordination, and communication within the open source community.

In 1997, Eric S. Raymond wrote The Cathedral and the Bazaar. In this fasting book, Raymond makes the distinction between two kinds of software development. The first is the conventional closed source development. These kind of development methods are, according to Raymond, like the building of a cathedral; central planning, tight organization and one process from start to finish. The second is the progressive open source development, which is more like a “a great babbling bazaar of differing agendas and approaches out of which a coherent and stable system could seemingly emerge only by a succession of miracles.” The latter analogy points to the discussion involved in an open source development process. In some projects, anyone can submit suggestions and discuss them. The ‘coherent and stable systems’ Raymond mentions often do emerge from open source software development projects. Differences between the two styles of development, according to Bar & Fogel, are in general the handling (and creation) of bug reports and feature requests, and the constraints under which the programmers are working. In closed source software development, the programmers are often spending a lot of time dealing with and creating bug reports, as well as handling feature requests. This time is spent on prioritizing and creation of further development plans. This leads to (part of) the development team spending a lot of time on these issues, and not on the actual development. Also, in closed source projects, the development teams must often work under management-related constraints (such as deadlines, budgets, etc.) that interfere with technical issues of the software. In open source software development, these issues are solved by integrating the users of the software in the development process, or even letting these users build the system themselves.

Open source software development can be divided into several phases. The phases specified here are derived from Sharma et al.. A diagram displaying the process-data structure of open source software development is shown on the right. In this picture, the phases of open source software development are displayed, along with the corresponding data elements. This diagram is made using the meta-modeling and meta-process modeling techniques.

The process starts with a choice between the adopting of an existing project, or the starting of a new project. If a new project is started, the process goes to the Initiation phase. If an existing project is adopted, the process goes directly to the Execution phase.

One can distinguish several different types of open source projects. First, there is the garden variety of software programs and libraries. They are standalone pieces of code. Some might even be dependent on other open source projects. These projects serve a specified purpose and fill a definite need. Examples of this type of project include the Linux kernel, the Firefox web browser and the OpenOffice.org office suite of tools.

Distributions are another type of open source project. Distributions are collections of software that are published from the same source with a common purpose. The most prominent example of a “distribution” is an operating system. There are a large number of Linux distributions (such as Debian, Fedora Core, Mandriva, Slackware, Ubuntu etc.) which ship the Linux kernel along with many user-land components. There are also other distributions, like ActivePerl, the Perl programming language for various operating system, and even the OpenCD and cygwin distributions of open-source programs for Microsoft Windows.

Other open source projects, like the BSD derivatives, maintain the source code of an entire operating system, the kernel and all of its core components, in one revision control system; developing the entire system together as a single team. These operating system development projects closely integrate their tools, more so than in the other distribution-based systems.

Finally, there is the book or standalone document project. These items usually do not ship as part of an open source software package. The Linux Documentation Project hosts many such projects that document various aspects of the GNU/Linux operating system. There are many other examples of this type of open source project.

There are several ways in which work on an open source project can start:

1. An individual who senses the need for a project announces the intent to develop the project in public. The individual may receive offers of help from others. The group may then proceed to work on the code.
2. A developer working on a limited but working codebase, releases it to the public as the first version of an open-source program. The developer continues to work on improving it, and possibly is joined by other developers.
3. The source code of a mature project is released to the public, after being developed as proprietary software or in-house software.
4. A well-established open-source project can be forked by an interested outside party. Several developers can then start a new project, whose source code then diverges from the original.

Eric Raymond observed in his famous essay “The Cathedral and the Bazaar” that announcing the intent for a project is usually inferior to releasing a working project to the public.

It’s a common mistake to start a project when contributing to an existing similar project would be more effective (NIH syndrome). To start a successful project it is very important to investigate what’s already there.

Hinduism The Way of Life. By Sangesh

Hinduism is a way of life under one understands the principles of Vedas and Upanishads. Veda is revealed knowledge. Just as knowledge of gravity was revealed by Newton, It is that several saints and Rishis have been awakened to certain transcendental Eternal Truths. These Rishis have realized that their true nature was not involved in or associated with body or mind and was not dependant on feelings, but in fact, was identical to the universal consciousness. In the Vedas, we find nowhere such a resonance, which can be attributed to show that Hinduism believes in many gods to one. Vedas, Upanishads and all other official written clearly, one God and one God that pervades the universe. Hinduism is a belief and practice. The belief in the basic tenets of Hindu Dharma is all that is needed. The rest belong with the individual maqui berry weight loss . Despite the raucous celebration with strong shrill bells Conches, the essence of the practice of Hinduism is a contemplative introspection and quiet meditation. A Hindu is trying to purify his ego called Jiva Atman. Hindus may do this by following the path of Dharma. No Indian shall be deprived of this right. Action is inevitable in life. There are two distinct types of actions – good and bad. A Hindu is invited to show moral judgments in all its actions. This is mainly because of the doctrine of karma. He is responsible for all actions. The objective is to collect good karma through many births. Because Hindus believe Atman is indestructible, it is estimated that the same Atman is transferred from one birth to another. But karma is never forgotten and worn by Jiva-Atman as a veil around a naked soul as birth, at birth.

How To Catch Walleye Under The Ice

If you are looking for some real adventure when winter rolls around, try walleye ice fishing on for size. You’ll never get bored because the tactics change as the season progresses, requiring you to make adjustments to your own fishing standards constantly. If you decide to go ice fishing for walleye, here are some tactics you can use to make your fishing trips successful. First of all, as the season begins, you should fish the smaller lakes. This is because, before the ice gets thick, the action is fast, and you may have a hard time locating the walleye below the surface. Smaller lakes will freeze faster, with the ice thickening sooner, making your job easier. With thicker ice, the fish will tend to slow down and move to a spot where they will stay relatively close, meaning that you can easily target them in a single spot. You won’t need to open several scholarships for high school seniors ice holes to find the walleye. Also, taking your gear to the smaller lakes early in the season and again later, before spring begins, will extend your winter fishing season, giving you more opportunities than you can imagine. If you are looking for the appropriate walleye fishing location, target underwater structures. You’ll find this is extremely successful for most anglers since fish can identify the structure as being something different from the flat lake floor. Bars, reefs, sunken islands, rock piles, and anything else that sticks out presents itself to fish as something by which to navigate and return to after feeding. The best ones are all along the migration route and used by fish to determine location. Remember, these creatures are not intelligent and work off instinct, which means that they need these extra sources of navigation to lead the way.
