Goldman Sachs Quant Unit Learned in 2007 Meltdown

Goldman Sachs Quant Unit Learned in 2007 Meltdown

here are the article highlights :

  • Quants use less leverage, more factors aiming for consistency
  • Assets climb to $110 billion in smart-beta, big-data offerings

This would be the time the data takes to be consumed and rebroadcast at a microwave tower, so you would multiply this number by the number of radio towers, and then add the speed of light for the aggregate distance covered between all the towers, and that would give you your theoretical latency between two geographic points in a microwave network.2 days ago• Like Follow TedTed Pascaru • Erik, you are correct. Thank you for the update. The only thing we can control is the latency from the Ethernet packet entering one IDU and exiting the other. Of course, there will be additional latency based on how far apart the link endpoints are spaced. When comparing to fiber optics, note that the speed of light in fiber is only 2e8 m/s. Therefore, a wireless link with our product can be lower latency than a comparable fiber run.
