Do you know how to rebuild your car’s engine?

Do you know how to remediate black mold spreading on the walls of a houseboat?

Do you know how to compile Linux to run on some custom arm hardware?

Do you know how to repair or rebuild a crumbling stone retaining wall?

There’s a good chance you may not know how to accomplish all of those tasks. There’s also a very good chance you may not care about knowing how to accomplish all of those tasks, as some of them may not be relevant to you. This is ok.

Finally, I know you’re posting on the Internet, but you don’t have to be an asshole, that’s a choice.
