U.S. Deploys Missile Defense System

Installation goes forward despite latest test failure

6 min read

The rockets may not glare and bombs may not burst in the air—to rephrase part of the U.S. national anthem—but the Bush administration is forging ahead with construction of what it terms an "operational" missile defense system. The official objective was to have a rudimentary system up and running by last December, but after a key interceptor test rocket failed to fire from the Marshall Islands on 14 December, the Pentagon's Northern Command said the system would not become operational until early this year [see photo, " Rollout"].

Two years ago, President George W. Bush ordered the activation by the end of 2004 of a system capable of defending the United States against a missile attack by a terrorist group or an unfriendly rogue state such as North Korea. Evidently, the administration's thinking now is that it's better to get on with the job—even if the system looks less than ready—than it is to be seen doing nothing.

Why Functional Programming Should Be the Future of Software Development

It’s hard to learn, but your code will produce fewer nasty surprises

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
