, Discovery Exercises
Discovery Exercise 1
Answers will vary. Common considerations include total cost of ownership, whether Oracle can run on
Linux, and whether hardware will be newly purchased or the NT servers upgraded. The distribution to be
chosen will likely be a major distribution, such as RedHat, SuSE, Ubuntu, or Debian. A report on Linux
advantages could include the following points:
-Linux and Linux software are continuously developed and rarely become abandoned projects.
-Bugs are fixed quickly in Open Source Software.
-Hardware support is abundant.
-Linux support is abundant.
-Customizing Linux is easy.
-The custom UNIX software used in the company can port to Linux easily.
-Linux and most software needed for this task are freely obtainable.
Discovery Exercise 2
Answers will vary. The GPL stands for the GNU General Public License and allows Open Source Software
such as Linux to be freely available and improved for an indefinite period of time. The Open Source
business model is different from conventional software; the value of software is based on its use and its use
generates profit indirectly by means of support, hardware sales, and so on. Open Source Software is
scrutinized by several developers worldwide via the Internet; thus software bugs and security loopholes are
found and fixed quickly. This makes Open Source Software very high quality software compared to
commercial software. Web sites that can be used for more information include but are not limited to the
following list:
-http://www.catb.org/~esr/writings/cathedral-bazaar/
-http://www.gnu.org
-http://www.opensource.org
Discovery Exercise 3
Answers will vary. Benefits to publishing software under the GPL include rapid collaborative development
in new areas, regular feedback, greater usage, and low chance of obsolescence. Companies can benefit from
the free development of other open source developers and reduce the cost of creating software packages by
contributing people to only those open source projects of corporate interest. To release software as open
source, you must read the open source definition and either subscribe to a license such as the GPL or create
a new one that is accepted at http://www.opensource.org.Then, you must coordinate the development by
providing an Internet-accessible means of communication between developers such as newgroups or
http://www.sourceforge.net. Both aforementioned Web sites also list the rules and resources available to
those who want to gain more knowledge about the open source procedure.
