Beside “National Day of China“, there is another reason to celebrate today:

Apple has decided to drop the NDA for released iPhone software.

We put the NDA in place because the iPhone OS includes many Apple inventions and innovations that we would like to protect, so that others don’t steal our work. It has happened before. While we have filed for hundreds of patents on iPhone technology, the NDA added yet another level of protection. We put it in place as one more way to help protect the iPhone from being ripped off by others.

However, the NDA has created too much of a burden on developers, authors and others interested in helping further the iPhone’s success, so we are dropping it for released software. Developers will receive a new agreement without an NDA covering released software within a week or so. Please note that unreleased software and features will remain under NDA until they are released.

Thanks to everyone who provided us constructive feedback on this matter.

• HeyCarsten: Basic Rubyisms Ruby Programmers Should Know
  The things that I know now, and take for granted, used to blow my mind. I’m going to go over a few Rubyisms that took me a while to pick up on, if only someone just took the 10 minutes to explain them to me right off the bat I would have been in the know so much sooner. Hopefully I can be that someone to you.
