Well, I've picked up the habit from my computer science teacher of naming |
2 |
variables and files things like doofus, fool, etc. The project I was working |
3 |
on was a program that would download and replace itself as an upgrade. It |
4 |
never worked because java would always change a few characters, but I guess |
5 |
something downloaded a lot. I may have also created a disk image I was using |
6 |
for something, and then forgot to delete it. I tried to open it with nano, |
7 |
but it crashed the computer, which would make this the first time. I have a |
8 |
gig of RAM, and that file was on a 30 gig partition, so I don't even want to |
9 |
know what happened when nano tried to read the entire file into RAM. I did |
10 |
shutdown -HF now at one point and fsck checked out fine. I'll have to do |
11 |
that again, considering I just deleted a several gig file. |

Thanks, |
