How the Internet Spans the Globe

Undersea cables are responsible for moving data between countries and continents at high speeds, making everything from photo sharing to financial transactions possible. These cables use fiber optics to move data at high speeds to land, where the data is then conveyed via fiber optics to homes and businesses. Yet, despite the billions of people […]

How to verify that quantum chips are computing correctly

A new method determines whether circuits are accurately executing complex operations that classical computers can’t tackle. Researchers from MIT, Google, and elsewhere have designed a protocol called Variational Quantum Unsampling, based on a novel quantum neural network, that verifies when photonic Noisy Intermediate Scale Quantum (NISQ) chips have accurately performed complex computations using light.

Lyft’s Journey through Mobile Networking

In 5 years, the number of endpoints consumed by Lyft’s mobile apps grew to over 500, and the size of our mobile engineering team increased by more than 15x. To scale with this growth, our infrastructure had to evolve dramatically to utilize new advances in modern networking in order to continue to provide benefits for […]

Facebook Invented a New Language for Machines to Solve Complex Math Equations

Using the same kind of technology that translates English into Mandarin, the neural network translates problems into solutions Despite being built by calculus, linear algebra, and an army of statisticians around the world, neural networks have trouble understanding math. Or at least, they have trouble understanding how humanity writes math equations. Facebook’s AI research team, […]

Most lidars today have between 1 and 128 lasers—this one has 11,000

Lidar sensors work by bouncing laser light off surrounding objects to produce a three-dimensional ‘point cloud.’ The first modern three-dimensional lidar was created for the 2005 DARPA Grand Challenge, a pivotal self-driving car competition. Today, many experts continue to see lidar as a key enabling technology for self-driving cars. That original 2005 lidar, made by […]

Intelligent DNS based load balancing at Dropbox

The Dropbox Traffic team is charged with innovating our application networking stack to improve the experience for every one of our users—over half a billion of them. This article describes our work with NS1 to optimize our intelligent DNS-based global load balancing for corner cases that we uncovered while improving our point of presence (PoP) […]

The Status of HTTP/3

HTTP/3 promises to make Internet connections faster, more reliable, and more secure. Born as ‘HTTP over QUIC’, an effort to adapt the HTTP protocol to run on top of Google’s own transport layer protocol, QUIC, it was later proposed as an IETF standard and it is currently an Internet Draft. In October 2018, IETF HTTP […]

Introducing the AI Index 2019 Report

The AI Index 2019 Report takes an interdisciplinary approach by design, analyzing and distilling patterns about AI’s broad global impact on everything from national economies to job growth, research and public perception. We’re excited to release the AI Index 2019 Report, one of the most comprehensive studies about AI to date. Because AI touches so […]

Why everyone is talking about WebAssembly

If you haven’t heard of WebAssembly yet, then you will soon. It’s one of the industry’s best-kept secrets, but it’s everywhere. It’s supported by all the major browsers, and it’s coming to the server-side, too. It’s fast. It’s being used for gaming.It’s an open standard from the World Wide Web Consortium (W3C), the main international […]

Engineering SQL Support on Apache Pinot at Uber

Uber leverages real-time analytics on aggregate data to improve the user experience across our products, from fighting fraudulent behavior on Uber Eats to forecasting demand on our platform. As Uber’s operations became more complex and we offered additional features and services through our platform, we needed a way to generate more timely analytics on our […]
