Open source Database Breakthrough: 10-80 times faster

The figure below shows the architecture of the new VectorWise engine. Theleft part shows the system architecture (“X100” execution engine andColumnBM buffer manager) and how it maps on the computer resources(CPU cache, RAM and disk). The right part shows a query in action, havingbeen decomposed into so-called relational operators (Aggregate, Project,Select and Scan) and execution …

Monolayer Nanotechnology Will Enable Silicon to Maintain Conductance for Smaller Devices and Sustain Moore’s Law Progress

Scientists at Rice University and North Carolina State University have found a method of attaching molecules to semiconducting silicon that may help manufacturers reach beyond the current limits of Moore’s Law as they make microprocessors both smaller and more powerful. The electronic properties of silicon, such as the conductivity, are largely dependent on the density …

Broadband Speeds, Issues, Stimulus and Prospects

Lack of competition is the reason why broadband speeds in the United States are not faster and at lower price. Other cable operators are concerned that not only will prices fall, but that the super-fast service will encourage customers to watch video on the Web and drop their cable service. Pretty much the fastest consumer …

How Much Has Technology Mitigated Poverty and Enabled More Personal Freedom?

Michael Anissimov discusses the idea that self-replicating factories, fed perhaps by acetylene, water, and the Sun (nanofactories) can lift most restrictions on freedom that come from finite resources. Michael refers to a piece by Peter Thiel that technology can enable Libertarianism. I remain committed to the faith of my teenage years: to authentic human freedom …

CRNano Chris Phoenix and MetaModern Eric Drexler Roundup

CRNano Increased Technical Content With Chris PhoenixChris Phoenix describes robotic control of molecular manufacturing without computation. In high-volume molecular manufacturing, computers can’t be used to control robots handling individual molecules, because computation requires too much power. However, computer-like control can be achieved without the use of computers, which means that robots can still be used …
