I've been using Linux for many years - back to when it was a hobby OS and the 0.x kernel was out. Even so, I'm always learning new things from the people around me -- much like with OTM / G-Log. Today's lesson came from a friend of mine, Ralph:

Not sure if either of you have com across this yet or not, but if you
have not, it is quite impressive. I did try this on other unix flavors
but it seems to be only on Linux.
Type "dmidecode" at a linux prompt and it will list out all
specifications of a linux machine.
System Manufacturer
Bios Level
Bios Settings
Hardware information such as
- Memory modules
- Processors
- PCI Cards
- System Cache
And much much more. Pretty impressive.
