Reaching for outsized impact means taking on risk, and high risk in pursuit of high payoff is a hallmark of DARPA’s programs.

We pursue our objectives through hundreds of programs.

More The ultimate goal of the DARPA Accelerated Computation for Efficient Scientific Simulation (ACCESS) is to demonstrate new, specialized benchtop technology that can solve large problems in complex physical systems on the hour timescale, compared to existing methods that require full cluster-scale supercomputing resources and take weeks to months.

Modern web development has many challenges, and of those security is both very important and often under-emphasized.

The modern software developer has to be something of a swiss army knife.

This chapter examines the relationship between authentication and authorization and how to build policies for each, describing a few common Authentication Policies and Authorization Policies to help you see how to work with these policy constructs.If you are upgrading your database from any previous version of the database to Oracle Database 11 If you are upgrading an Oracle RAC database with DBUA, then all necessary configuration is done for you automatically.If you are manually upgrading an Oracle RAC database, then most of the actions described in this chapter should be performed on only one node of the system. WARNING: -- EM Database Control Repository exists in the database. Direct downgrade of EM Database Control is not supported. 11g Upgrade Guide for instructions to save the EM data prior to upgrade. WARNING: -- The following sections describe the output of the Pre-Upgrade Information Tool.This assures that while individual efforts might fail—a natural consequence of taking on risk—the total portfolio delivers.More For reference, past DARPA research programs can be viewed in the Past Programs Archive.
