Nasdaq’s Technology Floor: Its President Takes Stock

Over the years, electronics technology has revolutionized virtually every securities market, most notably The Nasdaq Stock Market Inc. Nasdaq, a trademarked name, was the world's first market to handle trading not on an exchange floor but through a computer network linking display screens. But since its advent in 1971, changes in telecommunications and computer technologies have been ongoing, profound, and complex.

As a screen-based market, Nasdaq (which originally stood for National Association of Securities Dealers' Automated Quotations) has striven to stay on top of those developments. It is in the process of completing a US $180 million systems migration program--the largest single telecommunications and computer project undertaken by a U.S. stock market. The effort has involved replacing the entire Nasdaq system with a standards-based, client-server network, while moving from analog to digital network technology and upgrading the core systems to process 500 transactions a second--a rate that enables the market to handle at least a billion shares a day. With these systems, Nasdaq has the flexibility to constantly improve operational efficiency and regulatory oversight.

New AI Speeds Computer Graphics by Up to 5x

Neural rendering harnesses machine learning to paint pixels

Four examples of Nvidia's Instant NeRF 2D-to-3D machine learning model placed side-by-side.

Nvidia Instant NeRF uses neural rendering to generate 3D visuals from 2D images.


On 20 September, Nvidia’s Vice President of Applied Deep Learning, Bryan Cantanzaro, went to Twitter with a bold claim: In certain GPU-heavy games, like the classic first-person platformer Portal, seven out of eight pixels on the screen are generated by a new machine-learning algorithm. That’s enough, he said, to accelerate rendering by up to 5x.

This impressive feat is currently limited to a few dozen 3D games, but it’s a hint at the gains neural rendering will soon deliver. The technique will unlock new potential in everyday consumer electronics.
