BARI 2D: Headlines Are Not Enough

Why Objects Are Not Enough

Object−oriented programming hasn't created a viable software component industry. From a technical perspective, the reason for this failure lies in an insufficient consideration of the unique requirements of component software. Object−oriented programming too often concentrates on individual objects, instead of whole collections of objects, i.e., components. Component−oriented programming requir...

When Six Gates are Not Enough

We apply the pigeonhole principle to show that there must exist Boolean functions on 7 inputs with a multiplicative complexity of at least 7, i.e., that cannot be computed with only 6 multiplications in the Galois field with two elements.

Query Logs Alone are not Enough

The practice of guiding a search engine based on query logs observed from the engine's user population provides large volumes of data but potentially also sacrifices the privacy of the user. In this paper, we ask the following question: Is it possible, given rich instrumented data from a panel and usability study data, to observe complete information without routinely analyzing query logs? What...

Conservation biology: Genes are not enough

A study of correlated genotypic and phenotypic changes over a 2400-year period in a cave population of pocket gophers bolsters the idea that small, isolated populations can not only persist in a fluctuating environment, but may be able to adapt without genetic input from elsewhere.

HIV clinical trials are not enough.
