3-D printing breakthrough for lightweight syntactic foams could help submarines dive deeper

A team of materials engineers at the NYU Tandon School of Engineering developed syntactic foam filaments and processes to 3D print them using off-the-shelf commercial printers. Credit: NYU Tandon School of Engineering A team of materials scientists at NYU Tandon School of Engineering has developed the first process to 3-D print components of syntactic foam—extremely strong and lightweight composites used in vehicles, airplanes, and ships. Their breakthrough holds particular promise for submarines because it will enable manufacturers to print components…

It’s Hard To Change The Keys To The Internet And It Involves Destroying HSM’s

Photo by Niko Soikkeli / Unsplash The root of the DNS tree has been using DNSSEC to protect the zone content since 2010. DNSSEC is simply a mechanism to provide cryptographic signatures alongside DNS records that can be validated, i.e. prove the answer is correct and has not been tampered with. To learn more about why DNSSEC is important, you can read our earlier blog post. Today, the root zone is signed with a 2048 bit RSA “Trust Anchor” key.…

Stop Using Servers to Handle Webhooks – Square Corner Blog – Medium

Working Example So this is all good in theory, but it’s better to show an example of how we could implement a webhook handler on a FaaS platform. This example will be on Google Cloud Platform using their Google Cloud Functions, but the majority of what we cover would translate across platforms since we’re using JavaScript. For starters, we want to be sure to service the webhook request as quickly as possible since we don’t want it to timeout. If…

Fighting Financial Fraud with Targeted Friction – Airbnb Engineering & Data Science – Medium

How Airbnb Battles Chargebacks while Minimizing Impact to Good Guests On any given night, nearly two million people are staying in Airbnb listings in 191 countries around the world. The rapid growth of our global community is predicated on one thing: trust. We take a comprehensive approach to trust, which consists of both robust proactive measures and reactive support, but today I want to focus on some of the work we do ahead of time — and often in the background — to prevent fraudsters…

Meet Uber’s Software Engineer Apprentices

One of the beautiful things about programming is how many ways there are to learn it. With the explosion of online courses, tutorials, videos, and bootcamps, learning to code is more popular and accessible than ever for aspiring software engineers. With its Software Engineer Apprentice Program, Uber is an excellent landing pad for non-traditional engineers. Intended for developers who did not study undergraduate computer science, the program is a six-month introduction to industry-level software, complete with extended training and strong…

Android @Scale 2018 recap | Engineering Blog | Facebook Code

Last week we hosted the first-ever Android @Scale in New York City, bringing together expert Android developers to discuss the range of technical challenges that comes with serving millions or even billions of people. More than 250 attendees gathered in Midtown West to hear from engineering leaders at Audible, Facebook, Google, Instagram, Oscar Health, Pinterest, Spotify, Tumblr, and Twitter, who all shared a range of approaches, challenges, and assessments around building for Android. For a recap of the conference and…

Worm uploaded to a computer and trained to balance a pole

The analogue, natural version of C.elegans. Credit: TU Wien Is it a computer program or a living being? At TU Wien (Vienna), the boundaries have become blurred. The neural system of a nematode was translated into computer code – and then the virtual worm was taught amazing tricks. It is not much to look at: the nematode C. elegans is about one millimetre in length and is a very simple organism. But for science, it is extremely interesting. C. elegans…

Cognitive sensors in production processes

In the test and application center L.I.N.K. at Fraunhofer IIS in Nuremberg, researchers are testing cognitive sensor systems with localization and networking technology. Credit: Fraunhofer IIS As a direct result of Industrie 4.0, industrial production is becoming increasingly customized. And industry’s long-term goal is batch size one. In practice, however, digitalization still frequently means individual solutions that are only partially connected or not connected at all. As a consequence, neither subsequent processes nor advance planning can benefit from data recorded.…

Autonomous 3-D scanner supports individual manufacturing processes

The scanning system is able to measure any component in real time, making protracted teaching processes a thing of the past. Credit: Fraunhofer IGD Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible…

Kotlin and JaCoCo: Will They Blend? |

Kotlin… Developers are clamoring for it. Some are calling it the future of Android Development. Others are claiming it lacks the tooling to make it “production” ready. At Wayfair, we decided to give Kotlin a try and come to our own conclusions. Initially, we used it for our “debug” features. These tools were created for developers and employees to help us find and fix issues that customers might see in the wild. But, once Kotlin got it’s foot in the…
