Simplifying Media Innovation at Netflix with Archer

By Naveen Mareddy, Frank San Miguel, Mangala Prabhu and Olof Johansson Imagine you are developing a quick prototype to sift through all the frames of the movie Bright to find the best shots of Will Smith with an action-packed background. Your goal is to get the computer vision algorithm right with high confidence without worrying about: Parallel processing Cloud infrastructures like EC2 instances or Docker Container Systems The location of ultra high definition (UHD) video sources Cloud storage APIs for…

Building data services to bring education to millions, Part II

An embedded approach to in-platform analytics This post was co-authored with Juhi Singh and is Part II of the series (Part I here). In this installment, we cover Coursera’s In-Platform Dashboards, which serve descriptive and advanced analytics in easy-to-read visualizations directly on the site. At our partner institutions, these are consumed by instructors all the way up to program leaders; and among enterprise customers, from individual managers to heads of Learning and Development. The common thread? The need for aggregated…

A new, digitised era for European manufacturing

Credit: Suwin, Shutterstock Manufacturing in the EU is heading to another level that will make it more competitive than ever, thanks to better service models and to innovations such as digitisation, Big Data and the Internet of Things. In the face of Asian competition and cheaper labour abroad, Europe’s manufacturing industry must stay ahead of the game and remain competitive by offering superior value and services. The EU-funded PSYMBIOSYS project worked on revolutionising the product-service engineering environment through better intelligence…

Making Big Data Discoverable and Meaningful at Netflix

Experts build pulsed air rig to test 3-D printed parts for low carbon engines

Credit: Shutterstock/petrmalinak Researchers designed a unique facility for testing 3-D printed engine parts, to help reduce carbon emissions worldwide. The new Transient Air System Rig (TASR) was designed and built by Dr. Aaron Costall and his team from Imperial College London’s Department of Mechanical Engineering. The researchers hope it will help makers of large off-road and freight vehicles reduce the amount of carbon dioxide (CO2) they produce. The rig uses fresh air instead of hot exhaust gas, so the…

Credit: Fraunhofer IBP Around 40 percent of all employees in Germany work in an office. Often, however, office buildings do not meet the needs of modern workplace requirements which results in sensory overload, distraction and stress. International studies have shown that office workers perceive subpar acoustics as particularly distracting. On board this year’s MS Wissenschaft, Fraunhofer researchers demonstrate how…

Automated cluster management and recovery for Rocksplicator

Bo Liu | Engineering Manager, Serving Systems team Rocksplicator at Pinterest Rocksplicator (github) was open sourced by Pinterest one and half years ago. It was designed to solve common problems of building large-scale online stateful data systems on commodity hardware, such as RocksDB replication and request routing. Technical details about how Rocksplicator solves these problems can be found in the blog post Open-sourcing Rocksplicator, a real-time RocksDB data replicator. Since two years ago when the first Rocksplicator powered system started…

Open Source at Uber: Meet Shan He, the Architect Behind kepler.gl

Like many engineers working in data visualization, Shan He’s path was far from traditional. After studying architecture for seven years, she realized that her interests in design were too diverse to be contained by the physical world. So she went back to the drawing board and pursued a master’s degree in design computation, acquiring the skills necessary to bridge the divide between atoms and bits. In the process, she fell in love with the interconnected worlds of open source software…
