This site serves mostly as an easily accessible brain-dump of information I may need again, some day, after I've poured hours into solving a problem that doesn't come up very often. For instance, if I just spent an entire afternoon surfing the web to learn the proper technique to secure my server from brute-force SSH attacks, it makes sense to store that knowledge somewhere so I don't have to reinvent the wheel the next time I'm responsible for rolling out a new Linux server.
In the unlikely event that someone, somewhere, wants to contribute actively and directly to this little pool of knowledge... well, that person can find a way to get in touch with me and ask for a login. Until that time, this is pretty much my personal wiki. Go ahead and laugh. I don't mind.
