Posted by Hartmut Neven, Technical Lead Manager Image Recognition A new type of machine, a so-called quantum computer, can help here. Quantum computers take advantage of the laws of quantum physics to provide new computational capabilities. While quantum mechanics has been foundational to the theories of physics for about a hundred years the picture of reality it paints remains enigmatic. This is largely because at the scale of our every day experience quantum effects are vanishingly small and can usually not be observed directly.

Consequently, quantum computers astonish us with their abilities. Let’s take unstructured search as an example. Over the past three years a team at Google has studied how problems such as recognizing an object in an image or learning to make an optimal decision based on example data can be made amenable to solution by quantum algorithms. On the hardware side we are collaborating with D-Wave in Vancouver, Canada.

Servlet Performance Report: Comparing Apache Tomcat Performance. Part 1: Performance and Distinct Error Handling under Memory Load Frank C. Ziglar ©2006 Web Performance, Inc., v 1.1 Abstract This first part of this article measures performance information in order to distinguish the differences evident between the Windows® and Linux platforms. We find that given comparable hardware the performance differences introduced are almost trivial. When the server was pressed to capacity, our Windows installation was forced turn away some traffic with minimal alteration in serviced performance, whereas our Linux installation elected to service nearly all connections at the cost of introducing latency.

However, prior to reaching capacity, our Linux server appeared on average to be capable of servicing connections at a slightly faster rate than our Windows server. Introduction Sun's release of their J2EE specifications has been followed by enthusiastic developers crafting powerful applications which can be seen on the web in businesses of every size.
