iPhone responsiveness and memory usage

From fellow Big Nerd Ranch alum Jonathan Saggau:

iPhone responsiveness and memory usage: “I recently answered a question on a private mailing list about how to make a network – based (XML parsing and such) iPhone application more responsive. I’ve been encouraged to post it here by a few folks (Thanks, guys! You know who you are.). So, I figure ‘why not?’ Here you go. (Slightly modified)

Timeline 3D on sale

BeeDocs is running a Macworld Expo special for their wonderful app Timeline 3D. Through January 11, it’s only $30, less than half price.

I’ve been using this app for some personal history and genealogy stuff. But the prospects are really unlimited. Timeline 3D speaks XML. It can import RSS feeds, iCal calenders, iPhoto images, and other formats. It communicates directly with NetNewsWire, iPhone, iTunes, iCal, and Contacts.

This is really a cool, beautiful product. Support response has been fast and helpful. You should buy this app.
