Adam Finkel, OSHA*
As is the case with most other analytic tools used in environmental and health policy, skeptics have criticized the methods themselves when the only culprits are the practitioners who endorse misapplication of the tools. Bayes' Theorem has been successfully used to defend the stringency of a federal exposure standard (OSHA's methylene chloride regulation, 1997), and to demonstrate that conventional methods of estimating the uncertainty in cancer potency factors understate the reasonable upper bound (Finkel, 1988). However, using Bayes methods to "average" together conflicting scientific theories to generate a "best estimate" of risk represents a profoundly mistaken application of this otherwise indispensable theorem.

The Zend Optimizer is one of the most popular PHP plugins for performance-improvement, and has been available without charge, since the early days of PHP 4. It improves performance by scanning PHP's intermediate code and passing it through multiple Optimization Passes to replace inefficient code patterns with more efficient code blocks. The replaced code blocks perform exactly the same operations as the original code, only faster.
In addition to improving performance, the Zend Optimizer also enables PHP to transparently load files encoded by the Zend Guard.
The Zend Optimizer is a free product available for download from Zend Technologies. Zend Technologies also developed the PHP scripting engine, known as the Zend Engine.
