Nuclear Spacecraft to Explore Jupiter's Moons

SAN FRANCISCO (AP) -- NASA plans to dispatch a hulking nuclear-powered spacecraft to determine whether three of Jupiter's icy, planet-sized moons have the potential to harbor life.

The Jupiter Icy Moons Orbiter, or Jimo, would spend monthlong stints circling the moons Callisto, Europa and Ganymede, which are believed to have vast oceans tucked beneath thick covers of ice.

The unmanned craft, far larger and more powerful than any other sent to explore the outer solar system, would spend years studying the moons' makeup, geologic history and potential for sustaining life, as well as Jupiter itself. .... More

If an application is designed well, the reward for users is that they will learn it faster, accomplish their daily tasks more easily, and have fewer questions for the help desk. As a developer of a well-designed application, your returns on that investment are more upgrade revenue, reduced tech support, better reviews, less documentation, and higher customer satisfaction. The rewards of building a good-looking Aqua application are worth taking the extra time.

Dock Animation. Sometimes animating icons in the dock can be useful in communicating the status of the system or application.

Clicking an application in the dock should always bring forward an active window. If the user clicks on an open app's icon in the Dock, the application is active and all unminimized windows come along with it. I have found a few problems with windows behaving independently of their application.

So far in these articles, I have only dipped a toe or two into Aqua's pool. I have covered basic aspects of building an Aqua-compliant application, including the building of photo-illustrative/3D application icons. Now it's time to address other components of our Mac OS X application.

To put my money where my mouth is, in each new article I'll build a hypothetical application that illustrates the guidelines I'm covering. Today's application is called "Paint" and will be based on the photo-illustrative icon I created in my last article. Together we will complete each step, and by the end of the project we should have a well-designed, 95%-100% Aqua-compliant application. I'll leave some room for personal preferences and the fact that Apple changes the OS every few months.

Adopt Sheets. I really like the use of Sheets in OS X. The use of Sheets lets me know which window my dialogue belongs to without hijacking my system.

At WWDC, I listened to Apple representatives make some excellent points about taking the time to build a 100%-compliant Aqua application, and I think all developers need to look beyond the code and listen to what the folks at Apple have to say

Other examples of these animations might be to show the status of an FTP transfer, the progress of media being digitized, or an updated time signature. And don't forget that users may want to have some control over this, so give them plenty of options, including the ability to turn these functions off.

For my Paint application, I created a series of icons to simulate a rendering algorithm. While the application is performing this CPU-intensive task, you can always see the status of the document by the icon changing in the Dock.
