Cathedral vs Bazaar
The cathedral vs the bazaar is a comparison of two different ways to go at designing, building and testing of the source code for a program. On one side, the cathedrals theory, is to allow everybody to have full access to the source code after each release, but restricting access to the new source code being developed between updates. The bazaar on the other hand feels that by allowing full access to the source code during development and after the release allows for a better product and allows any issues with the program to be found, and fixed quickly. The way I think of it, is if you have ten to fifteen really good programmers working on a project, it will probably be a really good design but may have a lot of weaknesses because they only have their past experiences to work on. But if you take the whole world of programmers, developers, and hackers, chances are you will have a stronger and all around better program, because of the wealth of knowledge going into the source code. I would go with the bazaar design personally just because it makes more sense, it's important to this class because with out the comparison of these methods Linux, and a lot of other programs, wouldn't be what they are today.

b. How does Nautilus "know" which program to use to open different types of files? It uses several techniques to determine the MIME type, typically files with the same extension in the file name.
c. What are three commonly used Nautilus control bars? What kinds of tools do you find on each? The menu bar, toolbar, and location bar. Menu bar consist of drop downs with various functions File, Edit, View, Go, Bookmarks, and Help. Toolbar consist of navigation icons, such as back, forward, stop, and reload. Location bar shows you the path of file that is highlighted in the view pane. It also hold the magnification selector and the View as a drop-down list.
d. Discuss the use of the Nautilus location bar? It can be used to show pathname of the directory that is displayed in the view pane. You can also specify a local directory that you want displayed in the view pane.
The above questions were taken from the book "A Practical Guide to Fedora and Red Hat Enterprise Linux" by Mark G. Sobell, on page 277.
