"Robotics Research a Pillar of New $500M Advanced Manufacturing Partnership"
 June 24th, 2011, 
 Erwin Gianchandani, Computing Community Consortium (CCC) Blog

  "In just a few minutes, President Obama will announce the launch of
   the Advanced Manufacturing Partnership (AMP) in a speech on U.S.
   innovation and competitiveness at Carnegie Mellon University, saying
   his administration will provide $500 million to encourage the Federal
   government, industry, and academia to work together to develop new
   technologies that spur high-tech manufacturing and boost job creation."
   ..... "A key pillar of this new initiative is a $70 million investment
   for major advances in robotics being made available today."

"High Frequency Trading in Japan on the Uptick"
 August 23, 2010, HPCwire

  "High frequency trading (HFT), often called algorithmic or low latency
   trading, relies on fast computers and even faster networks to execute
   trades in sub-second and even sub-millisecond timeframes. It has 
   generated massive profits for those firms skilled enough to handle 
   the complexities of the software and hardware.

   As such, it has become the dominant method for equity trading in the
   US, but it's popularity is expanding worldwide, especially Asia. 
   HPCwire got the opportunity to ask Chuck Chon, chief technology officer
   of SBI Japannext, about the HFT business in Japan and to talk about
   some of the technology behind it."
