Things can go bad in a hurry…

What would be useful TechniqueApplicationMeans of Evaluation ProsCons Summary List of techniques with description Where could tool be used? What do you really get out of it? What standard statistical techniques are used? Confidence? What are the strengths? What are the weaknesses? (E.g., could tool be used in DDoS attack). What are the Heisenbugs*?

heisenbug /hi:'zen-buhg/ (From Heisenberg's Uncertainty Principle in quantum physics) A bug that disappears or alters its behaviour when one attempts to probe or isolate it. (This usage is not even particularly fanciful; the use of a debugger sometimes alters a program's operating environment significantly enough that buggy code, such as that which relies on the values of uninitialised memory, behaves quite differently.)jargon In C, nine out of ten heisenbugs result from uninitialised auto variables, Fandango on core phenomena (especially lossage related to corruption of the malloc arena) or errors that smash the stack.

Observations It would be useful to standardize--or at least identify--the evaluation methodologies –Identify statistical tools, methods, confidence Work seen here similar (same look and feel) to a large amount of RF measurement work done in the 60’s and 70’s –Has a survey of earlier work been done? Often the best use for a technology is NOT found in its first instantiation. –A good reason to do pure research… –Where else could these toys be used? Technology is transferred by people, not papers
