Everytime you change something you learn something new...

Note: This is an old post in a blog with a lot of posts. The world has changed, technologies have changed, and I've changed. It's likely this is out of date and not representative. Let me know if you think this is something that needs updating.

It's true. Take for example this morning when I upgraded sendmail innocently on my server only to discover a bunch of things suddenly stopped working. Some of the things were things I didn't even know people were using.

Hours of tailing the maillog and poking around the sendmail site, I discovered all kinds of exciting stuff about configuring sendmail for smtp authentication that I didn't know about.

Every time I upgrade Apache, I learn all kinds of new things as well. The only thing I wished, is that it wasn't quite so trial-by-fire. Of course, for that to be the case, I would have to know everything and there's a whole lot of stuff out there that I'd rather learn posteriori rather than a priori. Otherwise, I'd just spend all my time studying things I would never have time to use.
