US begins hypersonic weapons program
The US military has begun development of an ultra-high speed weapons system that would enable targets virtually anywhere on Earth to be hit within two hours of launch from the continental US.
Ten companies have been given grants by the Pentagon's Defense Advanced Research Projects Agency (DARPA) Pentagon for six-month "system definition" studies. If the Pentagon likes the results, a three-year design and development phase will begin.
The ultimate aim, slated for around 2025, is a reusable Hypersonic Cruise Vehicle (HCV) that can take off from a conventional runway in the US and strike targets up to 16,700 kilometres (10,350 miles) away.

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.

Posted by: Elizeus at January 12, 2004 05:59 PMThe simple fact is that, when all other factors are equal, where will consumers spend their money? I believe that in the long run, the best looking, easiest-to-use applications will also be the most successful. I think that's why Apple encourages developers to write programs that are 100 percent Aqua-compliant.

Okay, I just told you what Apple wants you to look out for with window positions, but in the real world, not everyone uses the hiding feature of the Dock, and it is unrealistic to be able to predict where each user will place their Dock at any given day or how large they will have it. However, you can build a feature into your application that allows spacing for the Finder. You can give users the option of where to position their windows and what area of the screen not to cross. I know that BBEdit provides me with this feature, and I wish more developers gave me more control over my windows.
