IMHO, the most nerve-wracking kind of code to ship:
1) is billing related
2) sends email
3) manages a complex state machine (esp. when state machine is related to #1 and #2)
This week we shipped a bunch of code that does all of the above. Whew.
I now stick my iPhone into my pocket upside down.
It felt so weird when this would happen accidentally with the iPhone 4, but with the 5 I'm beginning to realize it's a better orientation for pocket-to-hand.
I really like how all content on ADN is public, and you have to pay money if you want to post. This seems like a great model for other services too… and the freely accessible content keeps with the spirit of the Internet.
