The planning of construction projects can be estimated easily because the methods that are used and the cost of materials and services are pretty standard. These same techniques coupled with research work can also be used to estimate software development projects. But there is a way to pare down the process to essential stuff and this is what freelancers do to be successful in their trade.
The key to finishing projects efficiently is proper management of resources. This covers both both the tasks to be done and the time involved. Making sure that every procedure is accounted for and completed well before the target date is critical to the success of any project. This is true no matter how many people are involved in the project. One individual can handle several projects all at the same if he uses the appropriate project management tools.
Because most freelancers work with limited resources such as a smaller budget and manpower resource, they prefer to use reasonably priced, if not free, project management packages that they can custom –fit to suit their client’s needs. Using a web-based software is critical for this kind of task because they often come equipped with tools that can be used for planning and organizing the different elements of a project. And because the application is available online, it can be easily accessed which is a lot simpler than having to install an entire system on your computer. It is also flexible enough to allow multiple users to utilize it at the same time.
Some of the widely used software that can be used both for business and personal reasons include Redmine, Collabtive and Codendi. Redmine is a flexible application that is supported by multiple database sources. It is multilingual, includes a calendar and a Gantt chart that comes in handy for visual presentations. Collabtive is a management suite that features a time tracker, calendar, and a file manager, among others. It is also capable of importing projects and RSS updates. Codendi is a development project from Xerox. It provides all the tools required for software development and can be configured to fit specific needs and processes.
The development of open source software involves a process where the codes are made available to the public and can be used and modified by anyone. It is made by developers for end users. Because of the huge demand for software development in the past, new techniques had to be used to come up with a faster and more efficient process of creating varied computer applications. The previous methods were so structured because not many tools and technologies were available.
The advantage of using open source development is its high availability for free download and plug-ins. A lot of software are developed using the open source method which means that the source codes for utilization and design are accessible on the Internet and can be downloaded without fear of any proprietary or patent claim. There are other technologies that are used alongside open source development. An example of this is MySQL, which is the most utilized database management system in the world. It basically involves the operation perates a server that permits multiple users to access several databases simultaneously. Most open source projects that need the support of a comprehensive data management prefer to use MySQL.
Other related technologies include the Hypertext Preprocessor which is a writing language that is used for open source software to create unique and moving web pages. Applications like these are essential for the overall management of computer applications. It is compatible with different systems and can work with all kinds of platform. This is important because there are wide-ranging varieties of content management systems that are available today and to maximize this opportunity, it’s essential to have a tool that works with different kinds of resources.
A lot of widely used computer applications now are results of developments done by a community of users on software that have carried open source licenses. This is a type of license which permits different users to utilize the program and apply modifications following a specific set of conditions. Users can change the codes to suit their needs and test the capacity of the program. There are other types of licenses that are also given like the special and superceded licenses. This is the one though that’s preferable when developing web applications because of the flexibility that it allows. The ease of use that it gives users is the reason why it has also been called “free software”.
Most open sourced licenses are free and can be used by anyone. It can be worked on as a testing material, a personal resource and can even be utilized for commercial purposes. There are however specific limitations when using the software which involves the direct expression of its origin by naming the authors and the inclusion of the copyright statement. These licenses are reviewed and regulated by a community, the Open Source Initiative (OSI) which defines the requirement for the applications.
Some of the OSI-approved licenses that are widely used include Apache, Mozilla and Eclipse. They permit softwares to be shared and altered. If you are an entrepreneur, you can even sell it but you cannot control the way that the people will use it. This is entirely different from having proprietary rights which is when you develop something unique and having it appropriately licensed. So you can distribute the open license software under the same conditions that you are using it.
The flexibility that you are granted in using applications with this kind of license gives you freedom to use it for whatever purpose that will suit you but it does not issue any warranty. So in the event that the program fails or damages your stored data, you cannot blame anyone for it because the free use comes with certain risks. But for personal use, most free software generally meets the standard that most users require.
Commercial establishments are a different matter altogether because the type of software that they sell dictates the business model that they observe. But for technical processing and other forms of development work, adopting the open source programming framework is a safer and hassle-free option because the company does not have to undergo a complicated process of licensing a proprietary software.
