Miniaturized infrared cameras take colored photos of the eye

Fundus image taken by portable near-infrared fundus camera. Credit: Jun Ohta Look into one’s eye and you might be able to see their soul—or at least you can see signs of a stroke or diabetes. By looking at the blood vessels in the eyes, doctors can tell a lot about a person’s health. This can be done using fundus photography, which has been around for almost two centuries and is the standard imaging tool used by ophthalmologists. However, for many,…

Argo Tunnels: Spread the Load

We recently announced Argo Tunnel which allows you to deploy your applications anywhere, even if your webserver is sitting behind a NAT or firewall. Now, with support for load balancing, you can spread the traffic across your tunnels. A Quick Argo Tunnel Recap Argo Tunnel allows you to expose your web server to the internet without having to open routes in your firewall or setup dedicated routes. Your servers stay safe inside your infrastructure. All you need to do is…

Technology enables soft contact lenses to monitor glucose, medical conditions and deliver medications

Purdue University researchers combined a commercial soft contact lens with an ultrathin conformal sensor circuit. Credit: Purdue University Purdue University researchers have developed soft contact lenses that not only correct vision but also can monitor glucose and medical conditions and be used for ocular pain relief or drug delivery. Sensors or other technology previously couldn’t be used for soft contact lenses because the technology required a rigid, planar surface incompatible with the soft, curved shape of a contact lens. …

Networking @Scale 2018 recap | Engineering Blog | Facebook Code

Recently, we hosted more than 500 engineers at the Computer History Museum in Mountain View, California for our fourth Networking @Scale conference. As with previous Networking @Scale conferences, we look for operators of some of the largest “scale” networks and ask them to share their on-the-ground experiences in designing, building, and operating the networks. This year, speakers from IBM, Microsoft, Amazon, Blizzard, and Facebook walked through the entire OSI networking stack, from layer 0 to layer 7. We also hosted…

The Technology – Airbnb Engineering & Data Science – Medium

This is the second in a series of blog posts in which we outline our experience with React Native and what is next for mobile at Airbnb. React Native itself is a relatively new and fast-moving platform in the cross-section of Android, iOS, web, and cross-platform frameworks. After two years, we can safely say that React Native is revolutionary in many ways. It is a paradigm shift for mobile and we were able to reap the benefits of many of…

Ten Questions with Angus Croll, Author of If Hemingway Wrote JavaScript

I never thought I’d know how to code. Although I am a software engineer now, I studied history and literature in college and took a job in marketing after graduation. Working at a tech company made me hunger for engineering skills, so I resolved to learn programming. My friends were shocked. One of them, upon hearing my plans for a career transition, recommended a book called If Hemingway Wrote JavaScript. “If any programming book is going to speak to a…

Crumple up this keyboard and stick it in your pocket

A new tough and flexible keyboard is usable even after squeezing it. Credit: American Chemical Society Bendable portable keyboards for use with computers and other electronic devices are already on the market, but they have limited flexibility, and they’re fairly sizable when rolled up for transport. Now researchers have crafted an inexpensive keyboard that is so tough, flexible and thin that it can be crumpled up and tucked in a pocket without damaging it. The study appears in the journal…

Augmented reality helps build aircraft tanks

Through ambient markers on the tank the AR glasses know where the tank is and how large it is, allowing them to project a 3-D model. Credit: Markus Breig, KIT Walking through an unfamiliar city, getting directions or simulations of buildings that no longer exist – augmented reality is where virtual content and the real world come together. Scientists at Karlsruhe Institute of Technology (KIT) are developing an assistance system based on this technology which supports engineers in building and…

How to print a building—the science behind 3-D printing in construction

Building sites are going to look a bit different, in the future. Credit: Shutterstock It’s often claimed that 3-D printing – known in the trade as “additive manufacturing” – will change the way we live. Most recently, a team from Eindhoven University of Technology announced plans to build the “world’s first” habitable 3-D printed houses. But it’s one thing to build small, prototype homes in a park – it’s quite another to successfully use additive manufacturing for large scale projects…

Evaluation method for the impact of wind power fluctuation on power system quality

The left figure is an example of time series of fluctuation of power generation outputs. The right figure shows the histogram of the frequency of corresponding power fluctuation. When we can assume mild fluctuation as illustrated by the red line, modeling with normal distribution is acceptable. However, wind power generation fluctuation contains abrupt changes as illustrated by the blue line. Consequently, the corresponding histogram has slowly-decaying heavy tails, which represents the extremal outliers. Credit: Japan Science and Technology Agency (JST)…
