NO RATINGS
I'm surprised that it has taken this long. The vast majority of stock trades are currently performed or mediated by programmatic trading, so it only seems fitting that the signaling mechanism also be computer-driven, whether it involves a physical actuator and sensor or just a timer tick. On the face of it this is just a publicity stunt, but there have been a series of stories over the last few months about advance access to information that really highlight how ubiquitous automation is becoming in stock exchanges and how some people are taking advantage of it. The term 'day trading' has become quaint: Most of the action is at the millisecond level these days.

The ironic thing about the Universal Robots' arm ringing the NASDAQ bell is that it is not included in the ROBO index! In fact, most of the coolest robot makers are not listed because they are private companies--yet to make an intial publich offereing (IPO). However, all the big name public robot makers are on the list, such as Fanuc, Kuka and iRobot.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
