Carl Bialik from WSJ writes "Sun's DTrace trouble-shooting software won top prize in the Wall Street Journal's 2006 Technology Innovation Awards competition. It's the second time in three years that Sun took the top award. From the article, which also names a dozen other winners: 'Where most debugging takes place as software is being developed, DTrace analyzes problems with systems that are in production — running a company's database, say, or executing stock trades. It does this with a process called "dynamic tracing," which enables a developer or systems administrator to run diagnostic tests on a system without causing it to crash. Before DTrace, such tests often took days or weeks to reproduce the problem and identify the cause. With DTrace, performance problems can be tracked to their underlying causes in hours, even minutes.'"
The algorithm for finding the longest path in a graph is NP-complete.
For you systems people, that means it's *real slow*.
