Data Science at Scale: A Conversation with Uber’s Fran Bell

Fran Bell has always been a scientist; theorizing, modeling and testing how the world works. An ever-curious child, she was fascinated by the natural world, poring over biology and chemistry books, but was never satisfied with just knowing; she wanted to put her knowledge into practice, too. So, she translated her love of the physical sciences into a degree in quantum chemistry, and later, a career in data science at Uber. While Uber’s data-driven approach to research and its unprecedented…

New sensor system safeguards fuel quality at hydrogen filling stations

Credit: Oliver Dietze Fuel cell vehicles need hydrogen to operate, but that hydrogen has to be free of any contaminants that could damage the fuel cell. Professor Andreas Schütze and his research team at Saarland University are collaborating with research partners to develop a sensor system that can…

Watchmaking & Innovation: Technology Advances At The Exact Time

What recent innovations are shaking the world of watches? Lovers of mechanical watches, which can be properly conservative, often see innovation with skepticism, but that is changing. As Felix Baumgartner, co-founder of the Swiss Watches luxury brand Urwerk in Geneva and Zurich, said, “history and tradition are better respected by innovating and not simply imitating and repeating the past”. Mechanical watches were a feat of engineering. Around the year 1300, they became the first in Europe, but it took another…

Using Machine Learning to Ensure the Capacity Safety of Individual Microservices

Reliability engineering teams at Uber build the tools, libraries, and infrastructure that enable engineers to operate our thousands of microservices reliably at scale. At its essence, reliability engineering boils down to actively preventing outages that affect the mean time between failures (MTBF). As Uber’s global mobility platform grows, our global scale and complex network of microservice call patterns have made capacity requirements for individual services difficult to predict. When we’re unable to predict service-level capacity requirements, capacity-related outages can occur.…

How Data Inspires Building a Scalable, Resilient and Secure Cloud Infrastructure At Netflix

Netflix’s engineering culture is predicated on Freedom & Responsibility, the idea that everyone (and every team) at Netflix is entrusted with a core responsibility and they are free to operate with freedom to satisfy their mission. This freedom allows teams and individuals to move fast to deliver on innovation and feel responsible for quality and robustness of their delivery. Central engineering teams enable this operational model by reducing the cognitive burden on innovation teams through solutions related to securing, scaling…

Building fast interpreters in Rust

In the previous post we described the Firewall Rules architecture and how the different components are integrated together. We also mentioned that we created a configurable Rust library for writing and executing Wireshark®-like filters in different parts of our stack written in Go, Lua, C, C++ and JavaScript Workers. With a mixed set of requirements of performance, memory safety, low memory use, and the capability to be part of other products that we’re working on like Spectrum, Rust stood out…

Titanium pressure vessel for space exploration built successfully using the Wire + Arc additive manufacturing process

The full-scale prototype titanium pressure vessel. Credit: Cranfield University A team comprising of Thales Alenia Space, Cranfield University and Glenalmond Technologies have successfully produced a first full-scale prototype of a titanium pressure vessel to be used in future manned missions for space exploration. The piece is approximately 1m in height and 8.5kg in mass. Made of the titanium alloy (Ti-6Al-4V), it has been deposited using the Wire + Arc Additive Manufacturing (WAAM) process, which Cranfield University has pioneered over the…

Col. Clark talks of leadership at Academy Speaker Series

The MU Engineering Leadership, Engagement and Career Development Academy Speaker Series’ goal is to give students the opportunity to hear from tremendous leaders from a variety of backgrounds to show them tangible examples of leadership. And there are few better examples of leadership in the face of adversity than Col. John Clark. Col. John Clark was the keynote speaker at the second Speaker Series event, held in February at the MU Student Center. Clark was the keynote speaker at the…

Smart solutions to join carbon fiber reinforced plastics and metal

Smart solutions to join carbon fiber reinforced plastics and metal. Credit: Fraunhofer IGCV The engineering of lightweight vehicles requires manufacturers to combine functional metal components with lightweight, highly durable carbon fiber reinforced plastics. Fraunhofer researchers have developed a variety of solutions for joining such disparate materials – and will be showcasing their technology at this year’s Hannover Messe on April 1-5, 2019 using an e-scooter demonstrator (Hall 17, Booth C24). Whether it is buses, cars, scooters or bicycles, it seems…

Robotic solutions aim to improve rail bridge safety and carriage cleanliness

Credit: Heriot-Watt University Scientists at Heriot-Watt University, in partnership with rail industry body RSSB, are developing robotic solutions to improve rail carriage cleanliness in hard to reach places and to facilitate closer inspection of railway bridge arches. The first project will develop robotised mobile inspection platforms able to operate between and under the seats of a train carriage. Able to navigate and manipulate themselves in confined workspaces, the robot platforms will clean and detect hazards using an innovative algorithm. …
