If you find your server seems to be running out of disk space, the first thing you should do is figure out how full your disk really is. After that, you'll need a way to quickly zero in on which files and folders are using up the most disk space unnecessarily.
My wife is Korean, so I'm exposed to all kinds of interesting culture differences between America and Korea. I'd like to share a few of those culture differences so that people can learn more about Korean culture. I also want to show people that a lot of things we take for granted as just "how things are done" are actually nothing more than cultural norms that can and do vary from place to place.
