Midterm pre-test

These are questions to practice on for the upcoming midterm. Good luck!

1. What is the philosophical issue that GNU group is based on?
The appropriate way to promote software is to free it from commercial interests.

2. What is the stance of the BSD group?
Users should have easy access to the source of programs.

3. Which approach of development would the Emacs editor fall under according to Eric Raymond's paper, "The Cathedral and the Bazaar"?
Richard Stallman scrutinized every line of code which was added to the kernel. This would fall under the "Cathedral" style.

4. Does subversion follow the "Cathedral" or "Bazaar" philosophy? What about GIT?
subversion -> Cathedral
git -> Bazaar

5. In an SCM system, why shouldn't you share workspaces?
A workspace should be for a single user/project to reduce confusion. Also, the SCM system will be unable to track changes based on user or task.

6. What are the advantages for using a distibuted version control system like Git?
1) You have a perfect clone of the project from the server.
2) Since you have a offline copy, you don't need to go online and are not slowed down by server access.
3) Since its possible for multiple people to have a copy of the project, you can always get the project from a fellow developer.
4) You can add bits and pieces from different projects and incorporate them into your own version of the project.

7. A Standford study tested heavy multitaskers and light multitaskers in a variety of tasks. Did heavy multitaskers or light multitaskers do better when ignoring things? Storing and organizing information? Switching from one thing to another?
The light multitaskers outperformed the heavy multitaskers in each of the tests.

8. Name the benefits to using open source software.
1) Since the source code is available, any developer can make the changes that they want to make.
2) A community to collaborate with.
3) It's free.
4) It's ok to use, modify, and redistribute the project.

9. What are the requirements for on open source project?
1) You are allowed to redistribute the project for free.
2) The source code must be available.
3) The license must allow modifications and derived works.
4) Derived works might be required to be distributed under a different name or version number.
5) No discrimination against people or groups
6) No discrimination against use in a specific field
7) The license is redistributed along with the project.
8) The license must not be specific to a product
9) The license can't put restrictions on other programs included with the project

10. While using a version control system, two developers check out the same file and make changes to that file. What is this called? What problems could arise from this arrangement?
This is called nonlocking. The second user to commit the file will be told that the version they have is out of date. They will need to update before commiting their version of the file and make any changes to the code to resolve any inconsistency issues.
