We are happy to say that, this blog is very useful to learn about the new softwares....

Here lot of valuable information to make your mind as value........

Thank you.......

Open Source Software:

Open source software is computer whose sourse code is available under a licence that permits users to use,
change,and improve the software,and to redistribute it in modified or unmodified form.it is often developed in a
public,collaborative manner.it is the most prominent example of open source developement and often compared to user generated content.

Users should be treated as co-developers:

The users are treated like co-developers and so they should have access to the source code of the software.Furtheremore users are encouraged to submit additions to the software,code fixes for the software,bug reports,documentation etc. Having more co-developers increases the rate at which the
software evolves.Linus's law states that,"Given enough eyeballs all bugs are shallow."THis means that if many users view the source code they will eventually find all bugs and suggest how to fix them.Note that some users have advanced programming skills,and futhermore,each user's machine provides an additional testing environment.This new testing environment offers that ability to find and fiz a new bug.

Early Releases:

The first version of the software should be released as early as possible so as to increase one's chances of finding co-developers early.

Frequent Integration:
New code should be integrated as often as possible so as to avoid the overhead of fixing a large number of bugs at the end of the project life cycle.Some open Source projects have nightly builds where integration is done automatically on a daily basis.

Several Versions:

There should be atleast two versions of the software.There should be a buggier version with more features and a more stable version with fewer features.The buggy Version is for users who want the immediate use of the latest features,and are willing to accept the risk of using code that is not yet thoroughly tested. The users can then act as co-developers, reporting bugs and providing bug fixes. The stable version offers the users fewer bugs and fewer features.

High Modularization:

The general structure of the software should be mosular allowing for parellel development.

Dynamic decision making structure:

There is a need for a decision making structure, whether formal or informal,that makes strategic decisions depending on changing user requirements and other factors.
