"First things second, I'd like to apologize for the
lack of animation in my "voice" in this post. As you probably well
know (Even if you don't live in the USA), we're (hopefully) going
to find out who our next President is by this evening (I write
these a day in advance) and I'm somewhat distracted, even though I
know I shouldn't start caring until its late enough in the game for
any of the numbers to make a legitimate difference. My wife is
hanging on the 1% from here and 3% from there ;) I won't reveal
whom I voted for, since this blog doesn’t take any particular
political stance. I'll just let it be said that I'm really hoping
my candidate comes in. It's going to be a farce if the other
contender somehow manages to steal this thing...
"And, secondly, we'll walk through the many different (and
easily accessible) ways you can check up on your Linux system's
memory usage to make sure that all is well. Note that for some
commands, you need root privilege to get information of any value.
Most of these commands don't require that level of access, but (as
a rule) if you need to interface with the kernel (or access its
symbol/memory tables, etc) you'll probably just end up with a big
old raspberry when you try to run a few of these commands. Not to
worry, though: You'll be able to get more than enough information
from this mass of commands to make a reasonably accurate
estimation, no matter what level of access you have."
