GraphViz

I decided to start playing around with GraphViz, here are a few of my notes:
To call a file use the following command (works for me).

dot .gv | dot -Tpng >.png

This generates a png file.

Next up what the .gv file contains:

digraph G {Hello->World; World->Earth; World->Mars; World->Jupiter}

It looks like if you call it a digraph, and give it each of the start/finish points, it'll graph them for you.

I'll be back with more as I discover more.

TrueCrypt

I was having problems getting truecrypt to work on my ubuntu machine. Once I downloaded it and unzipped it there was no extension and for some reason my machine didn't know what to do with it. I simply renamed it with a .sh at the end and re-ran the file, everything worked as advertised at that point.

I.E. FROM: truecrypt-7.1a-setup-x86
      TO: truecrypt-7.1a-setup-x86.sh

Good Luck
