NASA’s X-59 supersonic jet will have a 4K TV instead of a forward window

NASA’s X-59 QueSST experimental quiet supersonic aircraft will have a cockpit like no other — featuring a big 4K screen where you’d normally have a front window. Why? Because this is one weird-looking plane.

The X-59, which is being developed by Lockheed Martin on a $ 247 million budget, is meant to go significantly faster than sound without producing a sonic boom, or indeed any noise “faster than a car door closing,” at least to observers on the ground.

Naturally in order to do this the craft has to be as aerodynamic as possible, which precludes the cockpit bump often found in fighter jets. In fact, the design can’t even have the pilot up front with a big window, because it would likely be far too narrow. Check out these lines:

The cockpit is more like a section taken out of the plane just over the leading edge of the rather small and exotically shaped wings. So while the view out the sides will be lovely, the view forward would be nothing but nose.

To fix that, the plane will be equipped with several displays, the lower ones just like you might expect on a modern aircraft, but the top one is a 4K monitor that’s part of what’s called the eXternal Visibility System, or XVS. It shows imagery stitched together from two cameras on the craft’s exterior, combined with high-definition terrain data loaded up ahead of time.

It’s not quite the real thing, but pilots spend a lot of time in simulators (as you can see here), so they’ll be used to it. And the real world is right outside the other windows if they need a reality check.

Lockheed and NASA’s plane is currently in the construction phase, though no doubt some parts are still being designed as well. The program has committed to a 2021 flight date, an ambitious goal considering this is the first such experimental, or X-plane, that the agency has developed in some 30 years. If successful, it could be the precursor to other quiet supersonic craft and could bring back supersonic overland flight in the future.

That’s if Boom doesn’t beat them to it.

Developers can now verify mobile app users over WhatsApp instead of SMS

Facebook today released a new SDK that allows mobile app developers to integrate WhatsApp verification into Account Kit for iOS and Android. This will allow developers to build apps where users can opt to receive their verification codes through the WhatsApp app installed on their phone, instead through SMS.

Today, many apps give users the ability to sign up using only a phone number — a now popular alternative to Facebook Login, thanks to the social network’s numerous privacy scandals which led to fewer people choosing to use Facebook with third-party apps.

Plus, using phone numbers to sign up is common with a younger generation of users who don’t have Facebook accounts — and sometimes barely use email, except for joining apps and services.

When using a phone number to sign in, it’s common for the app to confirm the user by sending a verification code over SMS to the number provided. The user then enters that code to create their account. This process can also be used when logging in, as part of a multi-factor verification system where a user’s account information is combined with this extra step for added security.

While this process is straightforward and easy enough to follow, SMS is not everyone’s preferred messaging platform. That’s particularly true in emerging markets like India, where 200 million people are on WhatsApp, for example. In addition, those without an unlimited messaging plan are careful not to overuse texting when it can be avoided.

That’s where the WhatsApp SDK comes in. Once integrated into an iOS or Android app, developers can offer to send users their verification code over WhatsApp instead of text messaging. They can even choose to disable SMS verification, notes Facebook.

This is all a part of WhatsApp’s Account Kit, which is a larger set of developer tools designed to allow people to quickly register and login to apps or websites using only a phone number and email, no password required.

This WhatsApp verification codes option has been available on WhatsApp’s web SDK since late 2018, but hadn’t been available with mobile apps until today.

Holography-based 3D printing produces objects in seconds instead of hours

 3D printers are useful devices for all kinds of reasons, but most have a critical weakness: they simply take a long time to actually make anything. That’s because additive manufacturing generally works by putting down an object one microscopic layer at a time. But a new holographic printing technique makes it possible to create the entire thing at once — in as little as a second… Read More
