Free and Open Source Software What is free and open source software? Free and Open Source software everywhere Opportunities for both businesses and individuals 1.Free software The definition can be broken down into two parts... "The term 'free' is used in the sense of free speech and not of free price." Free software ensures that the end users have freedom to run, copy, distribute, study and change the software. This is not to be confused with software which is available to the end user at no cost, which is known as freeware. Free software may be distributed with or without charge 2. Open Source software This is computer software with its source code (any collection of computer instructions written using a computer language)made available to the general public for use and or modification from its original design, which can be free of charge. Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community. The economic climate has hit all types of businesses, especially small to medium sized businesses and start ups. Businesses are looking to cut costs, increase profits and productivity. The use of free open source software can help businesses do this. A variety of benefits come with the use of free and open source software: The importance for businesses Quality software Customisation Freedom Supportive Available at minimal cost Secure Examples of businesses using such software Google use a version of Linux (an open source operating system) which they have modified for all their desktops and servers. Facebook was built on common open source software such as Apache, Linux, MySQL and PHP. They currently contribute to a variety of open source projects. FIJI Water have used Magento which is an free open source eCommerce platform that has allowed them to create a viable online business Other examples are Amazon, The White House, variety of e-businesses such Nike, Nestle Nespresso and Olympus. Free and open source software has somewhat provided both businesses and individuals a level playing field and opportunities to participate in the global community. Opportunities for business Opportunities for individuals The availability of free and open source software has allowed smaller businesses to participate in the global economy, especially online. Before smaller businesses did not have access to software needed to compete both online and within the global market. Businesses are now able to create more efficient processes via the use of free and open source software, not only to increase profits but to maximize productivity within the workplace. Businesses can now use free and open source software such as Wordpress, Magento and Drupal to move from a 'Brick-and-mortar' business to 'bricks-and-clicks' business model where it is much easier to compete online. Both students and underdeveloped nations that may not be able to afford operating systems and expensive software such as Microsoft office, which we are so accustomed to in developed areas. Now have the opportunity to use free and open source software at little or no cost. Free and open source software provides a learning environment for individuals. The ability to participate in such communities enables individuals to experiment with source code and learn new technical skills for "free" (such as programming). Problems with free and open source software Thanks for listeningFull transcript
Any questions? One of the main problems with free and open source software is that they are not straightforward to use or install. Possible training will need to be undertaken before a user can understand how to use certain software, which can mean additional costs are incurred. Another problem is that there is no comprehensive support or maintenance and this varies from one piece of software to another. There is also no guarantee of updates to the free and open source software, as this is reliant on developers contributing to new ideas, code and functionality. Various legal issues associated with free and open source software such as infringements of Intellectual Property rights and copyright issues. A brief history 1950's & 60's 1970's and 80's 1990 and 2000's 2000's and beyond Almost all software was produced by computer science academics and researchers working in collaboration. As such, it was generally distributed under the principles of openness and was not seen as a commodity in itself. In the early 1970s the first distributions of UNIX (operating system) were available at no cost to the government and academic researchers, but these versions did not come with permissions to redistribute or distribute modified versions.
Also a variety of computer vendors and software companies began charging for software licenses and imposing legal restrictions on new software through copy right, trademarks etc. The Linux kernel, started by Linus Torvalds, was released as freely modifiable source code in 1991. Linux remains free software and many businesses offer customized Linux-based products, or distributions, with commercial support.
In the mid to late 90s, when many website-based companies were starting up, free software became a popular choice, especially for web servers (Apache) 1970 2000 + 1950 1990 In 2005, Android was launched; which is the first Linux based operating system designed primarily for touchscreen mobile devices such as smartphones and tablets. Android has a large community of developers writing applications ("apps") that extend the functionality of the devices.
Android had a worldwide smartphone market share of 75% during the third quarter of 2012, with 500 million devices activated in total. ..Beyond Increase in familiarity of open source and free software and more use from both public and private sectors.
