Introducing Menu Maker: Uber Eats’ New Menu Management Tool

A restaurant’s menu is arguably its most important feature. When ordering online or via the app with Uber Eats, potential customers can’t peer in through a restaurant’s windows or smell the scents wafting from their kitchens, so digital menus become the de facto representations of restaurants’ personalities. As the Restaurant Menu Engineering team, our goal is to ensure that every restaurant in the world can accurately represent their offerings on Uber Eats. This seemingly simple task is actually quite complex…

Upgrading Pin Links from HTTP to HTTPS

Maria de Angelis | Summer 2019 Pinterest Engineer Intern HTTPS should be everywhere. Your website likely runs over HTTPS, giving your users a secure, encrypted connection, but what about all the outbound links? Can you guarantee that they all use HTTPS? In this post, we describe the steps we took to upgrade Pin links from HTTP to HTTPS by leveraging DuckDuckGo’s Smarter Encryption technology. Why HTTPS? While Pinterest runs entirely on HTTPS, it’s not the final destination for most users. As…

Test Flakiness – Methods for identifying and dealing with flaky tests

On September 12, 2019 I spoke at Assert(JS) in Toronto to talk about my journey with test flakiness at Spotify and some of the systems we have built over the years to address flakiness. Assert(JS) is a conference dedicated entirely to automated testing for web systems and this was the second year it has been run. This conference has hosted speakers that are well known in the automated testing world such as Kent Dodds, Justin Searls, Aaron Abramov, James Shore,…

Women in Engineering Week Empowers Women in STEM

The Fantastic Lego Ladies displayed their robots and interacted with COE students to see successful women pursuing engineering. Women in Engineering Week is a celebration of female accomplishments in STEM, empowering students through awareness and education. Each semester the College of Engineering hosts a week in honor of women in engineering with events to have open discussions and motivate students. The College kicked off WIE Week Nov. 11 with a visit with the Fantastic Lego Ladies, an all-female FIRST Lego…

New approach combines quantum physics and biology to improve enzyme activity measurements — ScienceDaily

In a new study, researchers showed that quantum light can be used to track enzyme reactions in real time. The work brings together quantum physics and biology in an important step toward the development of quantum sensors for biomedical applications. The complex molecules known as enzymes are responsible for many processes inside our bodies. However, they can be difficult to study with optical approaches because too much light will reduce their activity or even stop it altogether. In The Optical…

Lafferre Receives Distinguished Service Award

Thomas H. Lafferre received the Distinguished Service Award from the Mizzou Alumni Association. The Mizzou Alumni Association recently presented Thomas H. Lafferre, BS ME ’56, its 64th Annual Distinguished Service Award. Established in 1956, the Distinguished Service Award honors outstanding service by an individual whose sustained efforts and support have added to the excellence of MU. Lafferre retired in 1993 as Vice President of Operations for Monsanto Chemical. He joined the company upon graduation from Mizzou with his bachelor’s degree…

G-Scout Enterprise and Cloud Security at Etsy

As companies are moving to the cloud, they are finding a need for security tooling to audit and analyze their cloud environments. Over the last few years, various tools have been developed for this purpose. We’ll look at some of them and consider the uses for them. Specifically, we’ll take a close look at G-Scout, a tool I developed while working at NCC Group to look for security misconfigurations in Google Cloud Platform (GCP); and G-Scout Enterprise, a new tool…

Foam offers way to manipulate light — ScienceDaily

There is more to foam than meets the eye. Literally. A study by Princeton scientists has shown that a type of foam long studied by scientists is able to block particular wavelengths of light, a coveted property for next-generation information technology that uses light instead of electricity. The researchers, integrating expertise from materials science, chemistry and physics, conducted exhaustive computational simulations of a structure known as a Weaire-Phelan foam. They found that this foam would allow some frequencies of light…

No Do-Over for New Orleans Hard Rock Hotel

There is a saying I’ve heard more than once from fellow engineers involved in a rush job:  “There’s not enough time to do it right, but there’s always enough time to do it over.”  In other words, sometimes the only way managers will give engineers enough time to do a thing right is if it fails the first time.  Unfortunately for three construction workers who died and numerous other people injured and otherwise harmed by the collapse on Oct. 12…

COPA congestion control for video performance

Optimizing performance for internet applications can involve some intricate trade-offs. Sending too much data too quickly could incur retransmissions due to loss, which could hurt performance over time. But sending it too slowly could cause latency and stalls, which also hurt performance. In addition, different video experiences require different trade-offs for quality vs. latency. For an interactive experience, an application might be able to let quality dip a bit in favor of avoiding stalls. But when high-quality video is the…
