Yay! Free bug-fixing! I love this list. |

Actually, I have that script sitting on my computer since some time in |
| 23 |
2002. I didn't write it: it was written by a friend of mine and posted |
| 24 |
to the college unix users group mailing list, with comments as to what |
| 25 |
the proper scaling factors are all around. |
| 26 |
|
| 27 |
The scaling factors for the various components were chosen at that |
| 28 |
time because it seemed to be good, realistic numbers to compare |
| 29 |
performances of then-current desktop boxes. At least *we* felt it |
| 30 |
works better than bogomips. |
| 31 |
|
| 32 |
As to the part of looking at used memory instead of total memory: I |
| 33 |
don't remember it doing that, I have to go back to check. The double |
| 34 |
counting of scsi disks is a bug, mostly because this script was |
| 35 |
written before UDEV when it wasn't an issue. |
| 36 |
|
| 37 |
Lastly: this is just some good, not-too-clean locker-room-style fun. |
| 38 |
Don't take it too seriously! |

In this course we will of course make use of God's Units, namely |
| 45 |
h-bar = c = 1 |
| 46 |
but occasionally I will indulge myself in my personal addition to |
| 47 |
those units, in the form of |
| 48 |
2 = -1 = pi = i = 1 |
| 49 |
please feel free to interject whenever you feel confused, and I will |
| 50 |
make my best effort to clarify things. |
