Open Radar is a place for developers to share bug reports they have filed with Apple. Please post bugs there after you have filed them with Apple.
Understandably, third-party developers don’t have access to Apple’s bug database.
But that means they can’t see bugs someone else has filed, hence Open Radar. (Update 2009-01-04: to give you an idea of how difficult this can be, recently Apple closed some of bugs I filed as “Duplicate”, but I can’t read the original bug report they are tied back to. So I have no way of knowing what the status of the fix is, if they have a work around, or even if it’s already been fixed.)
Amazingly “(it was) less than 24 hours from idea proposition to (Open Radar) being built, deployed, and used.” That should give you an idea of how useful this can be.
Open Radar is still nascent. There’s no RSS feed for example. But with community involvement, it can only get better.
I’ve filled my bugs, have you?
