PROJECT: Grade Figure-Outerer (gfo0)
To successfully obtain, input, calculate, and derive your current overall status in the course through the use of a spreadsheet.
As an exercise in toning your abstraction abilities (literally seeing one thing, but understanding and using it as something else), there will be a number of 'generic' terms used throughout this (and other) documents throughout the course, requiring you to substitute in the pertinent information (else face confusion or error).
Some examples:
This sort of abstraction is very similar to that we will find in our utilization of variables in programming, where we can have a “name”, but the data associated with it can change based on various conditions.
Do not be a literalist computer! Start to exercise your abstraction abilities.
This document is written with TWO locations in mind:
There are commands you can ONLY run on one system or the other. Pay attention to any prompt cues in the given examples (or section headings, context of language leading up to any examples).
For example:
Please pay attention to your prompt, so you can perform the needed activity on the correct system.
For this project, you will be installing the sc spreadsheet on your Raspberry Pi, and creating a spreadsheet using it to tabulate and compute your current status in the class.
Don't forget to update the package database and apply any available upgrades:
yourpi:~$ sudo aptitude update ... yourpi:~$ sudo aptitude upgrade ...
To proceed on this project, you will also need to install the 'sc' package:
yourpi:~$ sudo aptitude install sc The following NEW packages will be installed: libncurses5{a} sc 0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.

There are two sources of information you can reference for sc operation.
With the installation of sc the manual page is made available for viewing ('q' to quit, up/down pageup/pagedown to view):
yourpi:~$ man sc
In the manual page there is given reference to an available sc tutorial, also installed with the sc package (tutorial itself tells you how to exit):
yourpi:~$ sc /usr/share/doc/sc/tutorial.sc
