Tracking the 2017 Solar Eclipse

How did U.S. riders use the Uber platform during the solar eclipse of Monday, August 21, 2017? To find out, we collected trip requests of around 40 major U.S. cities (Figure 1) near the totality path and put our data visualization tools to the test. In this article, we showcase how the recent solar eclipse affected Uber ride requests by harnessing the visualization power of our deck.gl and Voyager data visualization platforms. Figure 1: We tracked ride requests for 40…

First hints of possible water content on TRAPPIST-1 planets — ScienceDaily

An international team of astronomers used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1. The results suggest that the outer planets of the system might still harbour substantial amounts of water. This includes the three planets within the habitable zone of the star, lending further weight to the possibility that they may indeed be habitable. On 22 February 2017 astronomers announced the discovery of seven…

Tumblr Engineering — Building the Tumblr Neue Post Format

As a platform that prides itself on being a home for artists and creatives alike, it only makes sense that we allow our users to fully customize their Tumblrs to fully express themselves. Here at Tumblr, the world is your oyster not only in terms of looks but also in how you create your theme. I wanted to demonstrate how you too can develop a theme using Redux and React. Since there are plenty of docs and tutorials on how…

A new way to find pilots for US Navy unmanned aircraft

Volunteers try out the Selection for UAS Personnel, or SUPer. Developed with support from the Office of Naval Research, SUPer is a series of specialized tests assessing cognitive abilities and personality traits, to identify potential Navy and Marine Corps unmanned aviation systems (UAS) operators. Credit: Naval Aerospace Medical Institute Before acceptance to flight school, aspiring naval pilots must pass the Aviation Selection Test Battery (ASTB)—a rigorous intellectual exercise that evaluates things like aviation and nautical knowledge, math and engineering skills,…

Dermatologist developing wristband that tells you when you’re about to sunburn

Brian Matthys honed his internal instincts for when he had gotten too much sun during his years as a teenage lifeguard. Now, after a couple of decades as a dermatologist, Matthys is trying to use technology to give people a more scientific measurement. Matthys is working with several local companies to develop a fitness wristband that will not only track steps, it will also track sun exposure and tell the wearer when it’s time to put on more sunscreen…

Building Blockchain with Hyperledger : Developer’s Guide (Part 2)

Welcome to the Blockchain Revolution! In the last article of this developer’s guide, we went on to explore the basic building blocks starting from creating our own network to writing the client apps. Quickly summarizing, IBM’s block chain is based on Linux Foundation’ open source Hyperledger fabric. This fabric is like an operating system for data sharing networks, marketplaces, micro-currencies and decentralized digital communities.We recommend that you do a quick recap of our previous Blockchain developer’s guide before diving into the…

Amazon’s talking delivery drone would ask for help if it fell out of the sky

What’s nice about Amazon’s new drone patent is the prospect of having a little chat with your aerial-delivery vehicle when it’s dropping off your new camera. What’s not so nice is Amazon’s recognition that drones carrying consumer goods are going to be falling out of the sky. The Seattle e-commerce giant received a patent Aug. 29 for drones, aka unmanned aerial vehicles (UAVs) that could “conduct a speech dialog with a nearby person in order to request information and/or answer…

You need to design a website that looks and feels good and is capable of attracting a good number of viewers to it. Wix Editor is one of the best options when…

Smart tomographic sensors control industrial processes of tomorrow

Magnetic tomography developed at HZDR is an important prerequisite for controlling mold injection in continuous steel casting. Credit: HZDR / F. Bierstedt Modern parallel computer architectures are capable of processing huge amounts of data at high speed. This allows for the increasing use of imaging techniques as sensors to control machines and process plants. In the new European collaborative project TOMOCON twelve research institutions and 15 renowned industrial companies work together on the development of imaging-based industrial process control. The…

Making 3-D printing safer

Within the past decade, 3-D printers have gone from bulky, expensive curiosities to compact, more affordable consumer products. At the same time, concerns have emerged that nanoparticles released from the machines during use could affect consumers’ health. Now researchers report in ACS’ Environmental Science & Technology a way to eliminate almost all nanoparticle emissions from some of these printers. Recent studies on 3-D printers have found that when operating, the devices can release volatile organic compounds, aldehydes and nanoparticles into…
