POWER to the people

POWER to the people: "Released in 2003: 276 million transistors per processor
Like the POWER3 and POWER4, the POWER5 unifies the POWER and PowerPC architectures. The POWER5 is also based on the 130-nanometer copper/SOI process, and features communications acceleration, chip multiprocessing, a larger L2 cache, a memory controller on the chip, simultaneous multithreading, advanced power management, eFuse (morphing) and hypervisor technology. IBM servers built with the POWER5 feature up to ten LPARs capable of running up to 256 independent operating systems on the higest end. POWER5 processors can be found hanging about in iSeries and pSeries servers, as well as in the first IBM entry-level UNIX/Linux box, the OpenPower? line. IBM introduced the POWER5+? processors, which are built with a 90-nanometer process similar to that used with the Cell Broadband Engine, in 2005. POWER5+ ups the clockspeed significantly -- on a smaller die"

Improving Database Performance on Simultaneous

Read two biometrics, get worse results - how it works | The Register

Read two biometrics, get worse results - how it works | The Register: "Daugman produces the calculations governing the use of two hypothetical biometrics, one with both false accept and false reject rates of one in 100, and the second with the two rates at one in 1,000. On its own, biometric one would produce 2,000 errors in 100,000 tests, while biometric two would produce 200. You can treat the use of two biometrics in one of two ways - the subject must be required to pass both (the 'AND' rule) or the subject need only pass one (the 'OR' rule). Daugman finds that under either rule there would be 1,100 errors, i.e. 5.5 times more errors than if the stronger test were used alone.
He concludes that a stronger biometric is therefore better used alone than in combination, but only when both are operating at their crossover points. If the false accept rate (when using the 'OR' rule) or the false reject rate (when using the 'AND' rule) is brought down sufficiently (to 'smaller than twice the crossover error rate of the stronger test', says Daugman) then use of two can improve results. If we recklessly attempt to put a non-mathemetical gloss on that, we could think of the subject having to pass two tests (in the case of the 'AND') rule of, say, facial and iris. Dropping the false reject rate of the facial test (i.e. letting more people through) in line with Daugman's calculations would produce a better result than using iris alone, but if the facial system rejects fewer people wrongly, then it will presumably be accepting more people wrongly."
