Thanks for the suggestion, but dmidecode is not portable and is super
unreliable since it depends on upstream hardware vendors setting
reasonable values. Even running on a sample of 8-10 models of
motherboards all from the same vendor I get vastly different results
from dmidecode. I'd strongly discourage anybody from trying to integrate
it into other software for anything aside from general informational use.

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
