Welcome to Crypto Week 2019

The Internet is an extraordinarily complex and evolving ecosystem. Its constituent protocols range from the ancient and archaic (hello FTP) to the modern and sleek (meet WireGuard), with a fair bit of everything in between. This evolution is ongoing, and as one of the most connected networks on the Internet, Cloudflare has a duty to be a good steward of this ecosystem. We take this responsibility to heart: Cloudflare’s mission is to help build a better Internet. In this spirit,…

A free Argo Tunnel for your next project

Argo Tunnel lets you expose a server to the Internet without opening any ports. The service runs a lightweight process on your server that creates outbound tunnels to the Cloudflare network. Instead of managing DNS, network, and firewall complexity, Argo Tunnel helps administrators serve traffic from their origin through Cloudflare with a single command. We built Argo Tunnel to remove the burden of securing and connecting servers to the Internet. This new model makes it easier to run a service…

a scene-based complementary recommendation system

Eric Kim & Eileen Li | Visual Search On the Visual Search team at Pinterest, we’re constantly working on ways to help people discover new ideas visually, even when they don’t have the words to describe what they’re looking for. In a traditional image search system, the objective is to return results that are visually similar to a query image, however we’re working with a visual discovery engine where we need to identify and return visual components from a broader…

Industry needs studied as demand and production increases — ScienceDaily

Across the United States and Canada, demand for local specialty cut flowers is increasing, and production has correspondingly jumped. To accurately assess the needs of the industry, John Dole, Cristian Loyola, and Rebecca Dunning electronically surveyed 1098 cut flower producers and handlers regarding their current cut flower production and postharvest problems and customer issues. The illuminating results of their survey received careful analysis and are detailed in the article, “North American Specialty Cut Flower Production and Postharvest Survey,” as found…

No direct link between North Atlantic currents, sea level along New England coast — ScienceDaily

A new study by the Woods Hole Oceanographic Institution (WHOI) clarifies what influence major currents in the North Atlantic have on sea level along the northeastern United States. The study, published June 13 in the journal Geophysical Research Letters, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC) — a conveyor belt of currents that move warmer waters north and cooler waters south in the Atlantic — and historical records of sea level in coastal New England. “Scientists…

With precise control, researchers could make a mouse sing or not on command — ScienceDaily

Researchers at Duke University have isolated a cluster of neurons in a mouse’s brain that are crucial to making the squeaky, ultrasonic ‘songs’ a male mouse produces when courting a potential mate. In fact, they now understand these neurons well enough to be able to make a mouse sing on command or to silence it so that it can’t sing, even when it wants to impress a mate. This level of understanding and control is a key advancement in the…

Creating the “Superclass”: Improving object detection at Wayfair via product class clustering

Executive Summary Object detection is an important component of the computer vision workflow at Wayfair. The goal of object detection is to detect bounding boxes of the objects in an image along with the class information (Figure 1), which empowers many downstream applications. In this post, we will share a novel method we employ at Wayfair to improve the performance of the object detection model we use by making better use of our training data. The underlying idea of this…

No Coding Required: Training Models with Ludwig, Uber’s Open Source Deep Learning Toolbox

Machine learning models perform a diversity of tasks at Uber, from improving our maps to streamlining chat communications and even preventing fraud. In addition to serving a variety of use cases, it is important that we make machine learning as accessible as possible for experts and non-experts alike so it can improve areas across our business. In this spirit, we built Ludwig, an open source, deep learning toolbox built on top of TensorFlow that allows users to train and test…

Development of durable MTJ under harsh environment for STT-MRAM at 1Xnm technology node

Figure 1: (a) The developed MTJ structure in this study compared with (b) the conventional MTJ structure. Credit: Tohoku University Researchers at Tohoku University have announced the development of a new magnetic tunnel junction, by which the team has demonstrated an extended retention time for digital information without an increase of the active power consumption. Non-volatile memories are essential constituents in integrated circuits, because they can offer low power consumption. Among proposed non-volatile memories, spin-transfer-torque magnetoresistive random access memory (STT-MRAM)…

Student creates portable wallet to keep medication cool after being inspired by girlfriend’s story

Credit: Loughborough University A student from Loughborough University has designed a portable wallet to keep medication cool after being inspired by his girlfriend who was diagnosed with Multiple Sclerosis (MS). Bish Clow, 22, who studies Product Design and Technology, has created Chill—a flexible insulated pouch to store medication at refrigerator temperature. The aim of the product is to give people the freedom to enjoy trips away from home without worrying about how to keep their medication cold. Bish first came…
