Re: Serial Numbers/Copy Protection



A while back I wanted a laugh, so I looked at some widgets that charge money to see how easy they were to break. Some have code that is like:

function checkForLicense()
{
	//if you remove this code, you suck
	bleh bleh bleh
}

I guess that would detract some people, but probably not the people who wouldn't have paid money in the first place. You may also be able to write a Cocoa plugin to check for a license value, since I think those are compiled, and the user will not be able to see or edit them.

In general though... this is my personal opinion... most widgets are not worth actually charging money to use. Some are really useful, sure, but if you compare the amount you can do with a widget vs. the power of most $30 Cocoa applications, I think it's hard to justify saying that the widget is 1/5 or 1/10 as good.

On the other hand, a bunch of widget developers have thrown up donate buttons on their website. You probably won't make as much if you did that, but there are a bunch of people who will go out of their way and donate money, which is pretty awesome. But that way, you wouldn't have to worry about people hacking the licensing and all the headaches that come from that, and your widget will likely get a bunch more users, you'll get more feedback, and in the end the widget will be a lot better. At least, that's been my experience.

Probably not but you might come up with a way to encrypt the
Javascript code within your Widget or have the Widget phone home to
see if this is a valid user/license.

copy protecting the widgets once they are publicly available.


I have some ideas that would make cool little widgets that I think people
would pay a few bucks for. But this is not a questions asking: should I
sell...


The real question is this - is there a way to copy protect a widget?

Thanks
