Arduino: Problems With librxtxSerial.jnilib

Recently the Arduino IDE installation refused to start on my Mac with the following exception:

uncaught exception in main method: java.lang.UnsatisfiedLinkError: /Users/arun/arduino-0015/Arduio15.app/Contents/Resources/java/librxtxSerial.jnilib: no suitable image found. Did find: /Users/arun/arduino-0015/Arduino15.app/Contents/Resources/java/librxtxSerial.jnilib: no matching architecture in universal wrapper

Rather bizarre error and as far as I know, I hadn't mucked around with any settings. According to the Arduino forum it had something to with the Java version and suggested giving priority to Java 5 over Java 6. However this didn't work on my setup. Eventually I just downloaded the Java 6 compatible version of librxrxSerial.jnilib and replaced it in the package contents of the Arduino app. This fixed the problem.

iPhone OS 3.0 GM Seed

Earlier this week Apple made available the iPhone OS 3.0 GM Seed (build 7A341). It's the best build to date. Compared to the previous build, E*Trade's Mobile Pro application now works without crashes. Apple have also implemented one of my feature requests - the ability to retain the order of application icons between restores. So this upgrade was the smoothest of them all.

Apple have also provided an iTunes redemption code to pre-test a version of AOL’s AIM that makes use of the push notification service.

In the iPhone’s Settings page, push notifications can be controlled globally as well as for individual apps:
