Faster Neural Networks Straight from JPEG

Uber AI Labs introduces a method for making neural networks that process images faster and more accurately by leveraging JPEG representations. Neural networks, an important tool for processing data in a variety of industries, grew from an academic research area to a cornerstone of industry over the last few years. Convolutional Neural Networks (CNNs) have […]

Introducing Makisu: Uber’s Fast, Reliable Docker Image Builder for Apache Mesos and Kubernetes

To ensure the stable, scalable growth of our diverse tech stack, we leverage a microservices-oriented architecture, letting engineers deploy thousands of services on a dynamic, high-velocity release cycle. These services enable new features to greatly improve the experiences of riders, drivers, and eaters on our platform. Although this paradigm supported hypergrowth in both scale and […]

Sessionizing Uber Trips in Real Time

Uber’s many data flows required modeling the data associated with a specific task, such as a rider trip, into a state machine. The state machine lets engineers focus on just the events needed to successfully accomplish a trip. In one sense, Uber’s challenge of efficiently matching riders and drivers in the real world comes down […]

Uber lays off 100 safety drivers as it scales back self-driving tests

Uber is laying off its safety drivers in Pittsburgh and San Francisco—about 100 people in total. It’s the latest sign that Uber is scaling back its testing operations as it tries to move beyond the March crash that killed a pedestrian in Tempe, Arizona. Uber’s testing operations have been suspended nationwide since that fatality. It […]

A videogame that powers quantum entanglement experiments

The random number generator Abellan wanted to use? Randos online. His group would design a game that used the 1 and 0 keys on a phone or computer keyboard as controller buttons. As people played the game, those 1’s and 0’s they’d press would change the detector settings on each of the experiments across the […]

Early thoughts on Uber’s flying car from an aviation engineer

Earlier today I was reading about Uber’s newest unveiling of their concept for a flying taxi and I love it. It’s an electrically powered, multi-rotor plane with two rotors for vertical flight and one for horizontal flight. This is reminiscent of the V-22 Osprey tilt-rotor, where the propellers transition from vertical flight to horizontal – […]

Report: Software bug led to death in Uber’s self-driving crash

The fatal crash that killed pedestrian Elaine Herzberg in Tempe, Arizona, in March occurred because of a software bug in Uber’s self-driving car technology, The Information’s Amir Efrati reported on Monday. According to two anonymous sources who talked to Efrati, Uber’s sensors did, in fact, detect Herzberg as she crossed the street with her bicycle. […]

Ratings inflation on Uber and elsewhere

Uber asks riders to give their drivers a rating of one to five stars at the end of each trip. But very few people make use of this full scale. That’s because it’s common knowledge among Uber’s users that drivers need to maintain a certain minimum rating to work, and that leaving anything less than […]

Uber Is Ripping Off Frequent Riders and Here’s How to Avoid It

Uber appears to have the opposite of a rewards program. That is, it appears the more you use Uber as a passenger, the more they’re going to charge you per mile. We know Uber said they were going to experimenton charging different customers different rate, based on a variety of unpublished factors. My current belief […]
