Re-Architecting the Video Gatekeeper – Netflix TechBlog

By Drew Koszewnik This is the story about how the Content Setup Engineering team used Hollow, a Netflix OSS technology, to re-architect and simplify an essential component in our content pipeline — delivering a large amount of business value in the process. The Context Each movie and show on the Netflix service is carefully curated to ensure an optimal viewing experience. The team responsible for this curation is Title Operations. Title Operations will confirm, among other things: We are in…

Medical drones for accident and emergency

Remote or computer-controlled aircraft, commonly referred to as “drones” could revolutionize the way in which emergency medical supplies, such as bags of blood plasma, are delivered to areas hit by disaster, accidents or other life-threatening situations. Of course, drones are costly and require skilled operators. Writing in the International Journal of Business Continuity and Risk Management, a team from the U.S. has undertaken a cost analysis of using drones for this purpose. The team hoped to show that the delivery…

Strange warping geometry helps to push scientific boundaries — ScienceDaily

Atomic interactions in everyday solids and liquids are so complex that some of these materials’ properties continue to elude physicists’ understanding. Solving the problems mathematically is beyond the capabilities of modern computers, so scientists at Princeton University have turned to an unusual branch of geometry instead. Researchers led by Andrew Houck, a professor of electrical engineering, have built an electronic array on a microchip that simulates particle interactions in a hyperbolic plane, a geometric surface in which space curves away…

Facebook, Carnegie Mellon build first AI that beats pros in 6-player poker

Pluribus is the first AI bot capable of beating human experts in six-player no-limit Hold’em, the most widely played poker format in the world. This is the first time an AI bot has beaten top human players in a complex game with more than two players or two teams. We tested Pluribus against professional poker players, including two winners of the World Series of Poker Main Event. Pluribus won decisively. Pluribus succeeds because it can very efficiently handle the challenges…

Study provides framework for assessing historic wrought iron structures

The Institution of Civil Engineers will honor the research of Debra Laefer, a professor of civil and urban engineering at NYU Tandon, who employed terrestrial laser scanning (TLS) to examine Ireland’s historic Guinness Bridge. The research paper, published in the journal Engineering History and Heritage, garnered the 2019 Manby Prize from the institution, which lauded it for its exceptional quality and benefit to the civil engineering, construction and materials science community.

MoneyCon ’19: Uber Hosts its First FinTech Engineering Conference

The domain of payments, finance, and more generally FinTech is a fast-growing industry that reached a record global investment of $111.8B in 2018. The underlying technology that powers this incredible growth is also evolving rapidly. With gross bookings of $50 billion for 2018, a global reach of more than 700 cities across 63 countries on six continents, and an evolving, constantly expanding suite of products, Uber must tackle large-scale technical challenges to best engineer these systems.  Building financial systems at…

Auto-Tuning Pinot Real-Time Consumption

Pinot, a scalable distributed columnar OLAP data store developed at LinkedIn, delivers real-time analytics for site-facing use cases such as LinkedIn’s Who viewed my profile, Talent insights, and more. Pinot uses Apache Helix for managing cluster resources and Apache Zookeeper to store metadata. Pinot has wide adoption at LinkedIn, ranging from internal dashboards to site-facing applications. Pinot supports batch data ingestion (referred to as “offline” data) via Hadoop, as well as real-time data ingestion via streams such as Kafka. Pinot…

New sensor could shake up earthquake response efforts

A new sensor developed at Lawrence Berkeley National Laboratory combines laser beams with a position sensitive detector to directly measure drift between building stories, an essential part of assessing earthquake damages in a building and deeming them safe to reoccupy. Credit: Diana Swantek/Berkeley Lab Last week’s massive southern California earthquakes shut down Ridgecrest Regional Hospital throughout the July 4 holiday weekend while the tiny town of Ridgecrest assessed the damages. A new optical sensor developed at Lawrence Berkeley National Laboratory…

A Conversation with John Gage

To learn more about the origins of The Network is the Computer®, I spoke with John Gage, the creator of the phrase and the 21st employee of Sun Microsystems. John had a key role in shaping the vision of Sun and had a lot to share about his vision for the future. Listen to our conversation here and read the full transcript below. [00:00:13] John Graham-Cumming: I’m talking to John Gage who was what, the 21st employee of Sun Microsystems,…
