Introducing Commute Time for Jobs

Capturing Espresso updatesBrooklin, LinkedIn’s stream ingestion service, offers change-capture services from Espresso and Oracle data sources, and has a simple integration with Samza. In our pipeline, Samza listens to change-capture events from Brooklin for the Espresso commute preference updates and sends out Kafka messages for the isochrone requests. Getting and persisting isochronesThe requests to the Bing Isochrone API go through GaaP, LinkedIn’s Gateway-as-a-Platform. For each commute preference, we make several requests to Bing with different commute times. The individual isochrone…

How do you weigh a galaxy? Especially the one you’re in? — ScienceDaily

Pinning down the mass of a galaxy may seem like an esoteric undertaking, but scientists think it holds the key to unraveling the nature of the elusive, yet-to-be-seen dark matter, and the fabric of our cosmos. A new technique for estimating the mass of galaxies promises more reliable results, especially when applied to large datasets generated by current and future surveys, according to a research team led by Ekta Patel at the University of Arizona. Published in the Astrophysical Journal,…

End-to-end blood testing device shows capacity to draw sample and provide diagnostic results

Researchers from the Biomedical Engineering Department at Rutgers University have developed an end-to-end blood testing device that integrates robotic phlebotomy with downstream sample processing. This platform device performs blood draws and provides diagnostic results in a fully automated fashion at the point-of-care. By reducing turnaround times, the device has the potential to expedite hospital work-flow, allowing practitioners to devote more time to treating patients. The research has been published in a paper in the June 2018 issue of Technology. Diagnostic…

Food Discovery with Uber Eats: Building a Query Understanding Engine

At Uber Eats, we strive to help eaters find the exact food they want as effortlessly as possible. We approach this task through search and recommendation technologies,…

Deploying to Google Kubernetes Engine

Late last year, Etsy announced that we’ll be migrating our services out of self-managed data centers and into the cloud. We selected Google Cloud Platform (GCP) as our cloud provider and have been working diligently to migrate our services. Safely and securely migrating services to the cloud requires them to live in two places at once (on-premises and in the cloud) for some period of time. In this article, I’ll describe our strategy specifically for deploying to a pair of…

New method enables high quality speech separation

A new model isolates and enhances the speech of desired speakers in a video. (a) The input is a video (frames + audio track) with one or more people speaking, where the speech of interest is interfered by other speakers and/or background noise. (b) Both audio and visual features are extracted and fed into a joint audio-visual speech separation model. (c) The output is a decomposition of the input audio track into clean speech tracks, one for each person detected…
