"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."
