Google’s Chrome Canvas is a handy browser app for quick doodles

Posted: 20 Dec 2018 03:15 PM PST

Google has quietly released a progressive web app called Chrome Canvas that lets you make quick doodles that automatically save to your Google account, via Chrome Unboxed. That means you can just type in "canvas.apps.chrome" into a Chrome browser on any computer, and pull up a basic drawing app without having to download any programs or apps. Chrome Canvas first showed up as an app in a recent Chrome OS Dev build, but it's available now on any browser that supports WebAssembly, like Firefox.

The app's features are pretty simple for now, with a basic toolbar consisting of pencil, pen, marker, chalk, and eraser tools, in addition to a color palette. You can export your drawing as a PNG file when you're done, or pull up the same drawing on...

FCC slams spaceflight company with $900,000 fine over illegal satellite launch

Posted: 20 Dec 2018 02:53 PM PST

An Indian PSLV rocket, which was used to launch the Swarm satellites

Space startup Swarm Technologies, which launched four tiny satellites without government approval earlier this year, has agreed to pay $900,000 to the US Treasury for the unauthorized flight. The fine is part of a settlement with the Federal Communications Commission, which investigated the incident. The company will also have to adhere to a "strict compliance plan" and must submit extra documentation to the FCC whenever it hopes to launch more satellites in the future.

Swarm Technologies is a fairly new player in the space field, with hopes of eventually sending up to 100 satellites into orbit to beam global internet coverage to Earth for connected devices. On January 12th, the company launched its first satellites on an Indian PSLV...

Alexa now knows how high swans fly thanks to Wolfram Alpha

Posted: 20 Dec 2018 01:25 PM PST

Amazon's Alexa is now getting a Wolfram Alpha integration that will allow it to answer way more math and science questions. The feature is already available for some people, but you shouldn't expect to see it right away.

Alexa typically sources its knowledge from sites like Wikipedia, Yelp, Accuweather, and Stats.com, but before this latest integration, it didn't really have an answer for tough geography, history, or engineering inquiries. Now with Wolfram Alpha's help, Alexa can field questions like how high do swans fly, how many sheets of paper will fit in a binder, and how fast is the wind blowing right now. Wolfram Alpha is a resource that schools sometimes use as a trusted source of information.

It should be noted that Apple's...

Idiots with drones have shut down the UK’s second largest airport

Posted: 20 Dec 2018 01:17 PM PST

DJI Mavic Pro

Gatwick airport, the UK's second largest airport, has been closed since Wednesday night after it observed two drones flying nearby, reports The Guardian. The airport initially had its flights suspended at 9PM on Wednesday evening after the drones were spotted, and although it briefly reopened at 3AM, it was forced to close once more 45 minutes later after the drone flights resumed. The airport still remains closed, and is now advising passengers not to come to the airport for the foreseeable future, according to SkyNews.

The Army has been called in to support Sussex Police, which has assessed that the incident isn't terrorism-related, but a deliberate attempt to disrupt flights. Police are still looking for a way to disable the drones,...

Chinese hackers charged with stealing data from NASA, IBM, and others

Posted: 20 Dec 2018 01:14 PM PST

The Department of Justice (DOJ) has charged two Chinese nationals with being part of a decade-long, government-sponsored global hacking campaign that included the alleged theft of information from 45 US tech companies and government agencies, including NASA's Jet Propulsion Laboratory and Goddard Space Flight Center.

The charges, announced after the US government unsealed an indictment against the two individuals on Thursday, come at a time of high tension between the US and China. In the middle of a detente in the trade war between the two countries, the US recently coordinated with Canada to arrest the CFO of Huawei, one of China's biggest companies. The Chinese government has detained three Canadian citizens in response while...

Amazon sent 1,700 Alexa voice recordings to the wrong user following data request

Posted: 20 Dec 2018 12:38 PM PST

Amazon's Alexa is among the most ubiquitous personal voice assistants on the planet, and it also happens to live inside the living rooms and bedrooms of millions of Alexa device owners around the world. That gives Amazon the responsibility of being a proper steward of the data it collects when we ask Alexa a question and or engage in back-and-forth conversations with the software.

Unfortunately, a case from Germany has highlighted the potential pitfalls involved with using such a product, when Amazon accidentally sent a man 1,700 Alexa voice recordings of another user by mistake, according to German magazine c't.

Following the passage of the European Union's General Data Protection Regulation, or GDPR, any EU resident may demand a...

A shape-shifting drone suggests the future of rescue missions

Posted: 20 Dec 2018 12:26 PM PST

A new kind of drone has been designed to fold up its arms and squeeze into tight spots, potentially to scout around on rescue missions. Researchers from the University of Zurich developed a drone with four arms that can retract while flying to fit into gaps and holes. The goal is to send drones where humans can't go and make it easier to locate victims in a collapsed building in the event of an earthquake or fire.

To some extent, these types of rescue drones already exist, but they are sometimes too large and oblong-shaped to fit into most openings, like a crack in the wall or through fallen bars. The researchers say their new drone's shape-shifting abilities were inspired by the movement of birds. When faced with a narrow entrance, it...

Verizon is selling the Home Hub and two Home Mini speakers for just $129

Posted: 20 Dec 2018 12:26 PM PST

Verizon is picking up where B&H Photo and Google left off, continuing the aggressive deal that might be all many people need to outfit their house or apartment with Google Assistant this holiday season. When you buy a Home Hub smart display, two Home Mini smart speakers will be included for free, at a total price of $129. The Hub ordinarily retails for $149, with the speakers going for $49 each. This deal will end once Thursday, December 20th expires.

Obviously both products have been discounted at times during the holiday season — including right now at various retailers. But this bundle from the Google Store B&H Photo Verizon seems pretty tough to beat.

You'll gain three Google Assistant devices, all of which can respond to your voice...

Steam’s winter sale kicks off with deals on Just Cause 4, Yakuza 0, and more

Posted: 20 Dec 2018 11:41 AM PST

The annual winter sale has begun today on Steam, and as usual, you'll be able to find most of this year's most popular PC games for less than their usual cost. This sale will be going until January 3rd, 2019.

Valve has the tendency to change deals as its sales go on, and we hope that holds true this year because the offering so far isn't that great, nor is it varied. Here are the best PC game deals as of the time of writing:

The dean of UCLA Law explains the uncertain future of forensic science

Posted: 20 Dec 2018 10:57 AM PST

Shows like Law and Order and CSI have taught a generation of Americans that blood spatters and handwriting analysis are crucial for catching criminals. The reality, says UCLA School of Law dean Jennifer Mnookin, is that many of these so-called pattern evidence techniques used in forensic science are faulty and not supported by evidence.

In fact, when it comes to wrongful conviction cases (where new DNA evidence proves that someone was innocent), bad forensic science is the second most frequent contributing factor, behind only eyewitness testimony. There are real, and harmful, consequences to forensic science in the courtroom.

The Verge spoke to Mnookin, who recently wrote a paper on the uncertain future of forensic science, about how...
