5th Generation WIFI, 802.11ac

Five years have passed since the first 802.11n devices implementing a draft of the now-finalized specification hit the market. Over the years 802.11n support has become ubiquitous in the industry. Everything from smartphones to high-end notebooks support the standard. Even low cost products like the $99 Apple TV or $49 Roku LT ship with 802.11n support. With real world transfer speeds ranging from 30Mbps at the low end to 150Mbps at the high end, 802.11n is simply too slow to quickly move large files. It wasn’t too long ago that 100MB/s was reserved for high-end hard drives in PCs. Today, with SSDs capable of sustaining transfers of over 500MB/s, the bottleneck in many wireless homes is increasingly becoming WiFi.

NVIDIA Tesla GPUs Power World’s Fastest Supercomputer

The Tianhe-1A Supercomputer, located at National Supercomputer Center, Tianjin

Half the Size, Lower Power and 50% Faster Than World’s Top Supercomputer

Tianhe-1A, a new supercomputer revealed today at HPC 2010 China, has set a new performance record of 2.507 petaflops, as measured by the LINPACK benchmark, making it the fastest system in China and in the world today.

Tianhe-1A epitomizes modern heterogeneous computing by coupling massively parallel GPUs with multi-core CPUs, enabling significant achievements in performance, size and power. The system uses 7,168 NVIDIA® Tesla™ M2050 GPUs and 14,336 CPUs; it would require more than 50,000 CPUs and twice as much floor space to deliver the same performance using CPUs alone.

130 Feet Above the Amazon Rainforest, Scientists Sample the Last Pristine Air on Earth

The Amazon Rainforest, Manaus, Brazil

The full ramifications of the Industrial Revolution on this planet may never be known, not because the scope of the those changes can’t be measured but because the same rapid, spastic technological changes that hurled industry forward into a new era did the same for science. As such, pre-industrial science didn’t possess many of the instruments and technologies that allow modern science to happen.
