Amazon signs deal to boost its restaurant delivery service

Amazon wants to deliver more burritos and hamburgers to your doorstep. The e-commerce giant said Friday that it is partnering with online ordering platform Olo, in a deal that could boost the number of restaurant chains on its Amazon Restaurants delivery service. Under the deal, restaurants that use Olo can list their menus on Amazon Restaurants. The restaurants would prepare orders and Amazon would provide a worker to deliver it to the customer. Olo says 200 restaurant chains use its…

Facebook backs off plan for non-voting shares

Facebook founder and CEO Mark Zuckerberg, seen in 2016 with his wife Priscilla Chan, says he can fund the couple’s philanthropy with stock sales, and still maintain voting control at Facebook for the next 20 years Facebook on Friday reversed course on a plan to issue a new non-voting class of shares, avoiding a public trial in a suit filed by investors in the huge social network. The plan unveiled last year had been designed to allow founder and chief…

New technique spots warning signs of extreme events

Credit: CC0 Public Domain Many extreme events—from a rogue wave that rises up from calm waters, to an instability inside a gas turbine, to the sudden extinction of a previously hardy wildlife species—seem to occur without warning. It’s often impossible to predict when such bursts of instability will strike, particularly in systems with a complex and ever-changing mix of players and pieces. Now engineers at MIT have devised a framework for identifying key patterns that precede an extreme event. The…

Announcing Version 2.3.0 of our Client Libraries – Square Corner Blog – Medium

If you are familiar with How Square makes its SDKs then you know that one of the best ways to see what’s new in our latest SDK version is looking at the diff in our API specification on github (link). Let’s dive into each change: Orders Support The largest update in this release is support for Orders endpoints. The new Orders endpoints allow you to create itemized transactions online, and are a big improvement in reporting for online sales. You…

Carmakers face billions in European CO2 fines from 2021: study

Bigger cars could mean bigger fines as automakers fail to meet new emissions standards Big-name carmakers including Volkswagen and Fiat Chrysler face fines running into the billions for failure to meet tough new European carbon dioxide emissions limits slated for 2021, a study has found. “Only four out of 11 carmakers are forecast to meet the EU 2021 CO2 emission target, with the rest facing significant fines,” researchers from British firm PA Consulting said in a statement Friday. European…

Hacking a pressure sensor to track gradual motion along marine faults

The modified pressure sensor is now being tested at the bottom of Monterey Bay. Credit: MBARI/University of Washington Deep below the ocean’s surface, shielded from satellite signals, the gradual movement of the seafloor—including along faults that can unleash deadly earthquakes and tsunamis—goes largely undetected. As a result, we know distressingly little about motion along the fault that lies just off the Pacific Northwest coast. University of Washington oceanographers are working with a local company to develop a simple new technique…

Virtual reality tool developed to untangle genes

The team from the MRC Weatherall Institute of Molecular Medicine (WIMM) have been working in collaboration with physicists from Universita’ di Napoli and software developers and artists at Goldsmiths, University of London, to visualise complex interactions between genes and their regulatory elements in an…

Chemists report breakthrough in material design

Schematic depiction of a supertetrahedral aluminum crystal structure. Scientists from Utah State University, USA and Southern Federal University, Russia, computationally designed a new, metastable, ultra-light crystalline form of aluminum. Credit: Iliya Getmanskii, Southern Federal University, Russia If you drop an aluminum spoon in a sink full of water, the spoon will sink to the bottom. That’s because aluminum, in its conventional form, is denser than water says Utah State University chemist Alexander Boldyrev. But if you restructure the common household…

Computer-Aided Design: How It Improves Safety in Engineering

Computer-aided design or CAD has been a critical component in engineering for many years, especially in developing construction plans and in creating 3D models of devices, machinery, and infrastructure. More than designs and models, however, CAD is also an important tool in improving safety in the actual profession and, in turn, the products that they build. Modeling, Simulation, and Analysis CAD helps designers create more accurate drawings and models, down to the smallest nuts and rivets. Being able to visualize…
