In Brief
I like Github gists. They’re perfect for long-term publishing of any code snippet you might want to refer to later, without the overhead of a formal repository. I’ve used them as backing storage for a number of blog posts as well, and will do so again today:
Need to bulk update the contact information across a set of domain names you own in Route 53? I got you. Need to do it across a whole slew of AWS accounts (or anything across a number of accounts)? No problem.
Happy scripting!
