iPhone 3.0 has arrived, and with it push notification and in-app purchase. In this interview, Scott Kveton, Michael Richardson and Steven Osborn of Urban Airship talk about the ins and outs of these new capabilities, the challenges of maintaining server infrastructure as an iPhone developer, and their services that seek to alleviate those pain points.
In this interview, Stephen Lombardo and Billy Grey of Zetetic talk about SQLCipher, their transparent OSS encryption add-on to SQLite. SQLCipher encrypts/decrypts just above the write-from/read-to disk level which keeps the SQLite programming model unchanged. You do queries as you normally would, and all of the functionality is retained: your selects, inserts, updates, indexes, etc. all work as with an unencrypted database. Stephen and Billy also talk about getting an app with crypto into the store, including their experiences with the US Department of Commerce and the NSA’s technical review.
