Don't Be
A Dick
Do whatever you want with this code. Modify it, distribute it, build on top of it — for personal or commercial projects. Make it into something completely different. Never mention the original author. All of that is fine.
What you cannot do is use it to cause harm.
Harm to a person, a group, a company, a community, a government, animals, insects, or even the planet.
This code, or part of it, must not be used as a weapon.
"If you're wondering whether
what you're doing is okay —
it probably isn't."
Use it. Break it. Build something new.
The code is yours to use, fork, remix, and integrate. Personal projects, commercial products, open source derivatives — all welcome.
Using it as a building block for something of your own is exactly what it's here for.
Don't sell the box. Don't point it at people.
Wrapping it in a box and calling it a product is being a dick. If your business model is reselling this code unchanged, find another model.
Harm is harm — whether it targets a single person, a small being or a corporation. That's where this license draws its only real line.
None. And that's the point.
This license will never hold up in court. It's not meant to. The real judge is public opinion, and on the internet, things move fast.
This is a moral contract, not a legal one. It says something about who you are when you use it.
Common sense and basic decency are enough.
This license doesn't need fine print. The name says it all. If you have to ask, you already know the answer.
