Screencast Toolset

Best toolset that I've found for working on the Mac with screencasts:

1. ScreenR
for recording.
2. Jing for recording.
3. SimpleMovieX for merging.
   1. The videos merged using this tool will not work as intended on Vimeo or YouTube. They will stop at the very first location that was stitched together.
4. Final Cut Pro for merging.
   1. The videos merged using this tool can be seamlessly uploaded to top providers like YouTube and everything in the video works as intended. But the content may show up as Public by default! So make sure to secure your content afterwards.

RestKit - Getting Started w/ examples on iPhone

The lectures provided by Stanford University on iTunes offer a great start for anyone looking to kick-off iPhone development. Yet they leave a gap when it comes to driving the UI with an easy to use WebServices library. And the thought of "rolling your own" can be scary. This is where RestKit fills in the gap by providing an Objective-C framework that makes it easy to send/receive JSON messages and much much more...

If you want to quickly get some hands-on time with an iPhone simulator and all the features that RestKit has to offer then have a quick peek here.
