Softly, softly, catchy jelly: This ‘ultragentle’ robotic gripper collects fragile marine life


The creatures of the depths live in a very different world — one lethal to us. But our world is lethal to them as well, all sharp edges and rapid movements. If we’re to catch and learn about the soft-bodied denizens of the deep, our machines too must be soft — and that’s what this Harvard robotics research is all about.

Collection of samples from the deep ocean is a difficult task to do safely: Although these animals are subject to pressures and temperatures well beyond what any surface creature could handle, they are nevertheless very easily damaged by handling. Existing methods to collect them for study often involve sucking them into little containers that are kept pressurized and brought to the surface. But it would be nice to be able to snatch an intriguing critter up and inspect it in vivo, wouldn’t it?

To that end researchers at Harvard’s Wyss Institute have been working on simpler, safer ways to entrap these creatures temporarily, letting them go seconds or minutes later once the collector has gotten some good images or (I don’t know) sampled some mucus.

A little more than a year ago, they created an “underwater Pokeball,” a kind of soft geodesic form that could close around something like a jelly or drifting fish. But even with that kind of method, there’s still the possibility that it could get squished during closure.

So they continued their work, pursuing instead “noodle-like appendages” that, when not activated, are as pliable and harmless as cooked spaghetti, or rather fettuccine considering their shape.

Each “finger” is made of an “elastic yet tough silicone matrix,” and inside it are tiny fibers that remain slack when not in use, but which can be stiffened using a tiny amount of hydraulic pressure. This causes the whole finger to bend in a specific direction, in this case inwards at the same time as the others, scooping whatever is in their range into the soft 3D-printed “palm.” The grip is soft enough that it won’t harm the creature, but firm enough that it can’t just wriggle out.

At that point the researchers are free to do what they wish, though presumably after taking such care to catch the animal unharmed, they won’t be doing anything too rough with it.

There are few limitations on the size or length of the fingers, meaning they can be customized for different operations. The device you see pictured was made to be effective in catching common jellies, but the whole thing could easily be scaled up or down to handle bigger or smaller animals.

Of course the whole thing can be attached to a submersible, but it’s small and simple enough that it can also be made into a handheld gadget for manual sampling, should that what a given researcher prefers. They put together a prototype and “demonstrated the use of this hand-held soft gripper to successfully perform gentle grasping of three canonical jellyfish species.”

Here’s hoping this means less shredded jellies in our oceans, and perhaps one day you’ll be able to rent such a grabber while snorkeling and have a chance to examine fragile marine life closely without having to grab it with your hands (not recommended).

The researchers’ work was published today in the journal Science Robotics.

Zhiyun’s Smooth-Q2 aims to be the most portable quality smartphone gimbal available


Zhiyun has been steadily rolling out new gimbals for smartphones and dedicated cameras for a few years now, and the company’s quality and feature set has improved dramatically over time. Now, it’s launching the Zhiyun Smooth-Q2 smartphone gimbal on Kickstarter, with the aim of delivering a “truly pocket-size” gimbal that has all the bells and whistles you could ever want or need.

The Smooth-Q2 is indeed a portable powerhouse – the company sent me a pre-production unit to test, and though it’s not the final shipping hardware, it already works and feels like a polished, quality device. The first thing you’ll notice right away about the Smooth-Q2 is its size – it can indeed slip inside a coat or pant pocket, though you’ll need a fairly deep one to make that work. Even if you don’t necessarily have a compatible pocket, it’s hard to beat the Smooth-Q2 for sheer portability, and that’s bound to save you some packing space when you’re getting ready for your next trip.

Smooth Q2 1

There’s another recently released small-size smartphone gimbal on the market – the DJI Osmo Mobile 3. That has a clever method of folding down for easier packing, but the Smooth-Q2’s design, while similar in overall footprint, means it’s much easier to put in your actual pocket (or pack in a bag’s side pocket) than is the DJI version. And while both are incredibly easy to balance even if you’re a gimbal novice, I found the Zhiyun was actually the simpler of the two.

The Zhiyun Smooth-Q2 also feels more solidly constructed, though its simpler controls (it doesn’t have a trigger around or a zoom lever) may leave some creators wanting. There are some other advantages here, too, however – a quick release spring-loaded clip means you can detach your smartphone quickly for other uses without unbalancing the gimbal, and go right back to shooting when you’re done. Plus, you can connect via Bluetooth and control your smartphone’s native camera app directly, instead of relying on their ZP Play app – which you can still use for features like object tracking.

The Smooth-Q2 offers 16-hours of battery life, so you should easily make it through a day without requiring power, and it can do time lapses, with or without programmed motion, a vortex mode for capturing crazy rotational footage, and an aluminum body that should be able to withstand less-than careful stowage in your bag.

In terms of quality, the Smooth-Q2 really delivers in early testing with my iPhone XS Max, and I’ve included two quick sample clips so you can see for yourself. These are shot in the gimbal’s basic PF mode, in which the camera pans as you turn the gimbal side to side.

Zhiyun’s crowdfunding these but the company’s history and reputation mean that you can count on them to deliver. The entry-level price is set at $109 U.S. for backers, which is a $30 discount off the planned retail cost, and they should ship to backers in October according to the company.

Apple is turning Siri audio clip review off by default and bringing it in house


The top line news is that Apple is making changes to the way that Siri audio review, or ‘grading’ works across all of its devices. First, it is making audio review an explicitly opt-in process in an upcoming software update. This will be applicable for every current and future user of Siri.

Second, only Apple employees, not contractors, will review any of this opt-in audio in an effort to bring any process that uses private data closer to the company’s core processes.

Apple has released a blog post outlining some Siri privacy details that may not have been common knowledge as they were previously described in security white papers.

Apple apologizes for the issue.

“As a result of our review, we realize we haven’t been fully living up to our high ideals, and for that we apologize. As we previously announced, we halted the Siri grading program. We plan to resume later this fall when software updates are released to our users — but only after making the following changes…”

It then outlines three changes being made to the way Siri grading works.

  • First, by default, we will no longer retain audio recordings of Siri interactions. We will continue to use computer-generated transcripts to help Siri improve.
  • Second, users will be able to opt in to help Siri improve by learning from the audio samples of their requests. We hope that many people will choose to help Siri get better, knowing that Apple respects their data and has strong privacy controls in place. Those who choose to participate will be able to opt out at any time.
  • Third, when customers opt in, only Apple employees will be allowed to listen to audio samples of the Siri interactions. Our team will work to delete any recording which is determined to be an inadvertent trigger of Siri.

Apple is not implementing any of these changes, nor is it lifting the suspension on the Siri grading process that it halted until the software update becomes available for its operating systems that will allow users to opt in. Once people update to the new versions of its OS, they will have the chance to say yes to the grading process that uses audio recordings to help verify requests that users make of Siri. This effectively means that every user of Siri will be opted out of this process once the update goes live and is installed.

Apple says that it will continue using anonymized computer generated written transcripts of your request to feed its machine learning engines with data, in a fashion similar to other voice assistants. These transcripts may be subject to Apple employee review.

Amazon and Google had previous revelations that their assistants were being helped along by human review of audio, and they have begun putting opt-ins in place as well.

Apple is making changes to the grading process itself as well, noting that, for example, “the names of the devices and rooms you setup in the Home app will only be accessible by the reviewer if the request being graded involves controlling devices in the home.”

A story in The Guardian in early August outlined how Siri audio samples were sent to contractors Apple had hired to evaluate the quality of responses and transcription that Siri produced for its machine learning engines to work on. The practice is not unprecedented, but it certainly was not made as clear as it should have been in Apple’s privacy policies that humans were involved in the process. There was also the matter that contractors, rather than employees, were being used to evaluate these samples. One contractor described as containing sensitive and private information that, in some cases, may have been able to be tied to a user, even with Apple’s anonymizing processes in place.

In response, Apple halted the grading process worldwide while it reviewed the process. This post and updates to its process are the result of that review.

Apple says that around 0.2% of all Siri requests got this audio treatment in the first place, but given that there are 15B requests per month, the quick maths tell us that though it is statistically insignificant, the raw numbers could be quite high.

The move away from contractors was signaled by Apple releasing employees in Europe, as noted by Alex Hearn earlier on Wednesday.

Apple is also publishing an FAQ on how Siri’s privacy controls fit in with its grading process, you can read that in full here.

The blog post from Apple and the FAQ provide some details to consumers about how Apple handles the grading process, how it is minimizing the data given to data reviewers in the grading process and how Siri privacy is preserved.

Eero updates subscription plans


Router maker Eero is expanding its focus on subscriptions with a new two-tier system. Eero already had a $10 per month subscription called Eero Plus. It is now called Eero Secure+. The company is adding a cheaper plan with less features for $3 per month.

It seems a bit counterintuitive that Eero is selling software subscriptions. The company is mostly known for its tiny mesh routers that you can put in every room of your house.

Eero originally introduced a subscription back in 2017. It was designed as a sort of Amazon Prime of internet services focused on security. It included family plans to password manager 1Password, VPN service Encrypt.me and antivirus MalwareBytes.

Eero Secure+ is more or less a new name for Eero Plus. It costs $9.99 per month or $99 per year and includes the same services, as well as a few software additions, such as parental controls, filtering of dangerous websites at the network level as well as ad blocking.

Essentially, Eero intercepts DNS queries and blocks the ones to suspicious content — it could be a phishing site, an adult site or an ad network. The company replaces your default DNS with ZScaler’s DNS for that feature.

If you don’t want 1Password, Encrypt.me or MalwareBytes, you can now subscripte to Eero Secure to get those DNS-powered features. It costs $2.99 per month of $29.99 per year.

eeroSecure plans

As a reminder, Amazon acquired Eero in February 2019. Eero promised that its privacy policy wouldn’t change after the acquisition.

Still, paying a subscription for DNS filtering is a bit odd. Some public DNS services, such as Quad9, block access to malicious websites.

And if you’re looking for a fun weekend project, you can buy a cheap Raspberry Pi and play with Pi-Hole, an open source project that basically does everything Eero Secure does. You can also build your own VPN service as you should never trust VPN services. They don’t make you more secure and they can basically see all your network traffic.

Facebook will require political advertisers provide further credentials, or have their ads paused


Ahead of the 2020 elections, Facebook today announced it’s tightening requirements for groups buying political ads on the social network. The company last year began requiring advertisers get authorized to run ads about social issues, elections, or politics, which involves advertisers providing identification to confirm who they are and where they’re located — including a U.S. street address, phone number, business email and website matching the email. Starting in mid-September, Facebook says advertisers will now need to submit more information about their organization in order to run political ads.

Failure to submit this information will see their ads paused, the company says.

There are five options for submitting more information, three of which will confirm the advertiser is registered in some way with the U.S. government. This includes submitting a tax-registered organization identification number (EIN); a government website matching an email ending in .gov or .mil; or a Federal Election Commission (FEC) identification number.

By submitting this information, Facebook will label the advertiser a “Confirmed Organization” in its ad archive. The advertiser will also be allowed to use their registered organization name in the ad disclaimers and the “i” icon that appears on the upper-right hand corner of the ad will read “Confirmed Organization.”

For smaller businesses or local politicians who want to run ads about social issues, elections, or politics, they can choose to submit one of two other options instead: an organization name with a verifiable phone number, business email, mail-deliverable address and business website with a domain matching the email; or they can provide no organizational information and use the Page Admin’s legal name on their personal information document.

In either of these two cases, the “i” icon on the ad will read “About this ad” instead of “Confirmed Organization.”

Facebook says this “i” icon is how people will be able to see who is trying to influence them through the ad.

Facebook Ads Info

Posted by Facebook on Tuesday, August 27, 2019

“Now, with one tap, people will not only see information about the ad, but they’ll be able to see the information Facebook confirmed, such as whether an advertiser used an EIN or FEC identification number. This will allow people to confidently gauge the legitimacy of an organization and quickly raise questions or concerns if they find anything out of the ordinary,” the company explained in a blog post announcing the changes.

Despite Facebook’s rule around political ads, the company admitted that there have been several cases where advertisers attempted to put out misleading “Paid for by” disclaimers on their ads.

VICE, for example, demonstrated how easy it was to manipulate the system by placing ads on behalf of VP Mike Pence, DNC Chairman Tom Perez, and the Islamic State, which Facebook approved. Business Insider also ran fake ads pretending to be Cambridge Analytica, which Facebook also approved.

More recently, Facebook banned conservative news outlet The Epoch Times from running ads on its platform because of ad policy violations. The organization had hidden under page names like “Honest Paper” and “Pure American Journalism,” to bypass Facebook’s ad transparency system in order to run some $2 million worth of ads promoting the president and spreading conspiracy theories about his opponents.

In addition to the changes around the advertiser requirements, Facebook is updating its social issues list in the U.S. to include 10 categories, instead of 20 distinct subjects. This doesn’t represent a narrowing focus, but rather makes the categories themselves broader to encompass more topics. For example, the “Civil and Social Rights” category would include sub-topics like freedom of religion, LGBTQ rights, and women’s rights.

The new categories were based on the issue lists in countries who recently held elections, Facebook says.

Facebook also will no longer require some environmentally-focused ads to submit these additional requirements, based on user feedback. This includes ads that “discuss, debate or advocate for environmental issues,” those that encourage recycling, or those highlighting sustainable products.

In the months ahead, Facebook says it will be updating its Ad Library to make it easier to track and compare U.S. presidential candidate spending, and it will expand its policy to prohibit ads that discourage people from voting.

It will turn its attention to Pages, too, by requiring national candidates or elected officials to go through Page Publishing Authorization, to verify their Pages are using real accounts and are based the U.S. Facebook will then begin exposing more information about the Page, including the business or organization behind it.

“We know we can’t tackle these challenges alone. That’s why we’re calling for sensible regulation and working directly with governments, watchdogs and regulators,” the company wrote in the blog post, referring to Mark Zuckerberg’s pro-regulation op-ed, which called for rules on Facebook’s terms. “While our efforts to protect elections are ongoing and won’t be perfect, they will make it harder for advertisers to obscure who is behind ads and will provide greater transparency for people.”

Sony’s new a6600 flagship APS-C camera adds stabilization and over 2x better battery life


Sony announced two new APS-C mirrorless interchangeable lens cameras at a special event in New York today, and the announcements are big news for anyone who’s looking for a small, capable camera that can handle everything from sport shooting to vlogging. The new a6600 flagship takes everything that is great about the a6400 it introduced earlier this year, and adds a big battery boost, in-body stabilization, a headphone jack and real-time eye autofocus for video.

The a6600 otherwise looks nearly identical to the a6400 on paper – it has the same 24.2 megapixel APS-C sensor, ISO sensitivity that expands all the way up to 102400, burst shooting at up to 11 fps, 3k 40p internal HDR recording and the same quality viewfinder. None of that is in any way a criticism, however – these were all excellent specs when they debuted on the a6400 earlier this year, and they’ll serve a6600 owners just as well.

What’s been added should be plenty exciting, however, since it brings the in-body image stabilization (IBIS) that was present on the a6500 but did not make it into the a6400, which was more capable in many other ways. This is a clutch feature for video creators, and that’s a key market for the a6XXX line for Sony, especially with its class-leading reputation for autofocus and high-quality 4K video capture. Ditto the addition of continuous real-time eye AF during movie recording.

Finally, that bigger Z battery (which debuted on the company’s full-frame mirrorless camera line and brought big battery life gains there) will be a boon to video and still shooters alike. The existing battery that powers the a6400, along with the rest of the line, is rated at 360 shots, but that’s very low compared to the a7 III’s 610 shots, and Sony is saying you’ll get over 2x the shooting time with the Z battery in the a6600 compared to its predecessor.

The a6600 retails for $1,400 U.S. for the body alone, and is available in a kit with the 18-135 lens from Sony for $1,800. It’ll be on sale in November.

Alpha Universe alpha 6100 ilce6100 selp1650 right black

Sony also unveiled a new entry-level option in its a6XXX line, the a6100. You get a lot of the benefits of the more expensive cameras here, including the same AF system (albeit without real-time Eye AF for movies, which is only on the a6600), and 4K 30p internal recording. You don’t get S-Log or HLG recording options, or HDR, however, and there’s no in-body stabilization. You’re also stuck with the older battery, lower maximum ISO sensitive (51200 in expanded mode) and a lower resolution electronic viewfinder. Still, all told it’s a good bargain – especially since you get Sony’s outstanding real-time object tracking autofocus feature.

The a6100 retails for $750 U.S. for the body alone, and is available in a kit with the 16-50 lens from Sony for $850, or with both the 16-50 and the 55-210 for $1,100. It’ll be on sale in October.

Alpha Universse 16 55mm G 70 350mm G.91159cb549bb213dddcb831882634037.ryg3hbESB

Finally, there are two new lenses which will be hugely beneficial to Sony APS-C camera shooters looking for pro-level options. The E-mount 16-55 F2.8 G gives you a focal range on par with the best glass available on other camera systems, and the E 70-350mm f4.5-6.3 G OSS gives you a really long reach zoom (105-535mm equivalent on a 35mm) with built-in stabilization in a relatively small package. The new 18-55mm lens sells for $1,400 and will be sold in October, and the 70-350mm goes on sale in November for $1,000.

Insta360’s tiny new GO stabilized camera could be game-changer for social video


Insta360 has quickly established itself as the leader in 360-degree video capture, at least for the consumer market, and its new GO stabilized camera builds on that legacy and extends some of the tech it’s built into the category of more traditional, non-360-degree footage.

The $199.99 GO is truly tiny – it weighs under an ounce, and measures less than two inches tall, by under an inch wide. It’s tiny, and that’s ideal for the use case that Insta360 has in mind for this device – wearing it or mounting it virtually anywhere for capturing quick clips. The GO’s all about quick action grabs, with a 30-second cap on clip recording, which you trigger by pressing the lone control button on the device (a second press stops the clip, unless you let it run the entire 30 seconds).

Sport Running Easy Clip

GO’s design is clearly meant for social sharing, but its secret weapon vs. just using your smartphone or making use of other devices is that it packs Insta360’s FlowState stabilization on board. This is the company’s digital video stabilization feature, which works to great effect in its Insta360 One X 360-degree camera for smoothing out footage so that even in intense action sequences it’s not nausea-inducing.

GO also features a magnetic body, which is designed to work in tandem with a variety of accessories, including backs for securing them unobtrusively to clothing, an underwater housing (the camera itself is IPX4 rated, which means essentially it’s protected from splashes but not meant to be submerged), and mounts for sticking to things like surf boards or vehicles. It can capture clips at resolution of up to 2720×2720, but it crops the image to 1080p (at 25 fps) for export as a result of the stabilization tech.

Shooting modes include a standard 25fps as mentioned, as well as a 30fps time-lapse which can record up to 8 hours (which will output a 9 second video) and a hyper laps mode that can shoot for up to 30 minutes to generate a 5 minute video. It can capture photos, too, exporting square images at 2560 x 2560 resolution, or a number of landscape options reading down from there.

In addition to simplifying capture, the Insta360 GO also hopes to make editing and sharing much easier, too, with its FlashCut auto editing feature. This software tool uses “AI” according to the company, in order to find the best clips (you can even sort by category, ie. ‘food’) you capture throughout the day and then stitch them together in a final edit. You can also fully tweak the edits it provides if you’d rather be a more involved creator.

The biggest limitation, based on just reading the specs and not having had a chance to test this out yet, is that the battery life is rated at around 200 clips per day, based on an average of 20 seconds per clip. But that’s including recharging the camera when not in use using the included Charge Case, which has 2.5 extra charges using its built-in battery. That and the recording limitation could prove challenging to anyone looking to create a lot of content with this camera, but on the other hand, it’s very easy to ensure you have it with you at all times – even when your smartphone isn’t nearby.

Collection

At $199.99, the Insta360 GO isn’t exactly cheap – but it does include the Charge Case, a pendant with a magnet you can use to wear it around you neck, a stand, a clip for clothing and a sticky mount for putting it on most smooth surfaces. You can also laser-engrave it if you purchase it directly via Insta360’s website. But after some missed starts for this category like the Google Clips camera, and earlier entrants like the Memoto and Narrative Clip lifelogging cameras, I’ll be curious to see if Insta360’s additional features help this gadget define a category.

Hackers to stress-test Facebook Portal at hacking contest


Hackers will soon be able to stress-test the Facebook Portal at the annual Pwn2Own hacking contest, following the introduction of the social media giant’s debut hardware device last year.

Pwn2Own is one of the largest hacking contests in the world, where security researchers descend to find and demonstrate their exploits for vulnerabilities in a range of consumer electronics and technologies, including appliances and automobiles.

It’s not unusual for companies to allow hackers put their products through their paces. Tesla earlier this year entered its new Model 3 sedan into the contest. A pair of researchers later scooped up $375,000 — and the car they hacked — for finding a severe memory randomization bug in the web browser of the car’s infotainment system.

Hackers able to remotely inject and run code on the Facebook Portal can receive up to $60,000, while a non-invasive physical attack or a privilege escalation bug can net $40,000.

Introducing the Facebook Portal is part of a push by Trend Micro’s Zero Day Initiative, which runs the contest, to expand the range of home automation devices available to researchers in attendance. Pwn2Own said researchers will also get a chance to try to hack an Amazon Echo Show 5, a Google Nest Hub Max, an Amazon Cloud Cam, and a Nest Cam IQ Indoor.

Facebook said it would also allow hackers to find flaws in the Oculus Quest virtual reality kit.

Pwn2Own Tokyo, set to be held on November 6-7, is expected to dish out more than $750,000 in cash and prizes.

But that’s including recharging the camera when not in use using the included Charge Case, which has 2.5 extra charges using its built-in battery. That and the recording limitation could prove challenging to anyone looking to create a lot of content with this camera, but on the other hand, it’s very easy to ensure you have it with you at all times – even when your smartphone isn’t nearby.

Collection

At $199.99, the Insta360 GO isn’t exactly cheap – but it does include the Charge Case, a pendant with a magnet you can use to wear it around you neck, a stand, a clip for clothing and a sticky mount for putting it on most smooth surfaces. You can also laser-engrave it if you purchase it directly via Insta360’s website. But after some missed starts for this category like the Google Clips camera, and earlier entrants like the Memoto and Narrative Clip lifelogging cameras, I’ll be curious to see if Insta360’s additional features help this gadget define a category.

Fitbit’s CEO discusses the company’s subscription future


At a small event in Manhattan this week, Fitbit laid out its future for the press. Tellingly, the event was far more focus on the company’s software play, with the big hardware announcement feeling almost rushed at the end.

Along with an increased focus on health care providers and enterprise, much of its revenue strategy will be tied up in Fitbit Premium, a $10 a month subscription service. The offering marks a major shift for a company whose identity has been so closely tied to hardware for its first decade of existence.

The announcement comes a year and a half after the release of Versa. The smartwatch has helped the company begin to right the ship after several quarters’ worth of financial struggle. And while last quarter found Fitbit’s valuation stumbling a bit on the heels of a disappointing performance by the Versa Lite, the company says it continues to be committed to its core hardware offering.

Following the announcement of Fitbit Premium and the Versa 2 smartwatch, we sat down with CEO and co-founder James Park to discuss the company’s path and what the future holds for Fitbit.

The state of Fitbit

Brian Heater: The flow of today’s briefing was different. In previous years, the company’s always led with hardware.

James Park: You noticed that it was pretty conscious, and I think it’s just to reinforce the fact that what we’re working on is not just about hardware anymore. But it’s equally important that the services component is an important part of our strategy, and also an important part of an overall solution, again, people healthier.

YouTube to reduce conspiracy theory recommendations in the UK


YouTube is expanding an experimental tweak to its recommendation engine that’s intended to reduce the amplification of conspiracy theories to the UK market.

In January, the video-sharing platform said it was making changes in the US to limit the spread of conspiracy theory content, such as junk science and bogus claims about historical events — following sustained criticism of how its platform accelerates damaging clickbait.

A YouTube spokeswoman confirmed to TechCrunch it is now in the process of rolling out the same update to suppresses conspiracy recommendations in the UK. She said it will take some time to take full effect — without providing detail on when exactly the changes will be fully applied.

The spokeswoman said YouTube acknowledges that it needs to do more to reform a recommendation system that has been shown time and again lifting harmful clickbait and misinformation into mainstream view. Though YouTube claims this negative spiral occurs only sometimes, and says on average its system points users to mainstream videos.

The company calls the type of junk content it’s been experimenting with recommending less often “borderline”, saying it’s stuff that toes the line of its acceptable content policies. In practice this means stuff like videos that make nonsense claims the earth is flat, or blatant lies about historical events such as the 9/11 terror attacks, or promote harmful junk about bogus miracle cures for serious illnesses.

All of which can be filed under misinformation ‘snake oil’. But for YouTube this sort of junk has been very lucrative snake oil as a consequence of Google’s commercial imperative being to keep eyeballs engaged in order to serve more ads.

More recently, though, YouTube has taken a reputational hit as its platform as been blamed for an extremist and radicalizing impact on young and impressionable minds by encouraging users to swallow junk science and worse.

A former Google engineer, Guillaume Chaslot, who worked on the YouTube recommendation algorithms went public last year to condemn what he described as the engine’s “toxic” impact which he said “perverts civic discussion” by encouraging users to create highly engaging borderline content.

Multiple investigations by journalists have also delved into instances where YouTube has been blamed for pushing people, including the young and impressionable, towards far right points of view via its algorithm’s radicalizing rabbit hole — which exposes users to increasingly extreme points of view without providing any context about what it’s encouraging them to view. 

Of course it doesn’t have to be this way. Imagine if a YouTube viewer who sought out at a video produced by a partisan shock jock was suggested less extreme or even an entirely alternative political point of view. Or only saw calming yoga and mindfulness videos in their ‘up next’ feed.

YouTube has eschewed a more balanced approach to the content its algorithms select and recommend for commercial reasons. But it may also have been keen to avoid drawing overt attention to the fact that its algorithms are acting as de facto editors.

And editorial decisions are what media companies make. So it then follows that tech platforms which perform algorithmic content sorting and suggestion should be regulated like media businesses are. (And all tech giants in the user generated content space have been doing their level best to evade that sort of rule of law for years.)

That Google has the power to edit out junk is clear.

A spokeswoman for YouTube told us the US test of a reduction in conspiracy junk recommendations has led to a drop in the number of views from recommendations of more than 50%.

Though she also said the test is still ramping up — suggesting the impact on the viewing and amplification of conspiracy nonsense could be even greater if YouTube were to more aggressively demote this type of BS.

What’s very clear is the company has the power to flick algorithmic levers that determine what billions of people see — even if you don’t believe that might also influence how they feel and what they believe. Which is a concentration of power that should concern people on all sides of the political spectrum.

While YouTube could further limit algorithmically amplified toxicity the problem is its business continues to monetize on engagement, and clickbait’s fantastical nonsense is, by nature, highly engaging. So — for purely commercial reasons — it has a counter incentive not to clear out all YouTube’s crap.

How long the company can keep up this balancing act remains to be seen, though. In recent years some major YouTube advertisers have intervened to make it clear they do not relish their brands being associated with abusive and extremist content. Which does represent a commercial risk to YouTube — if pressure from and on advertisers steps up.

Like all powerful tech platforms, its business is also facing rising scrutiny from politicians and policymakers. And questions about how to ensure such content platforms do not have a deleterious effect on people and societies are now front of mind for governments in some markets around the world.

That political pressure — which is a response to public pressure, after a number of scandals — is unlikely to go away.

So YouTube’s still glacial response to addressing how its population-spanning algorithms negatively select for stuff that’s socially divisive and individually toxic may yet come back to bite it — in the form of laws that put firm limits on its powers to push people’s buttons.

How to Use a Chromecast as a Second Computer Monitor


chromecast-second-monitor

If you’ve got a shiny new Chromecast. right now you’re wondering what this little gadget can achieve. Not only is it easy to use, but it has a lot of handy functions to make your life easier. Casting your Chrome browser or duplicating your desktop to another display is one of its productivity tricks.

Here’s how you can turn your Chromecast-enabled TV into a second computer monitor.

How to Cast Browser Tabs

Setting up your Chromecast with a TV isn’t difficult to do as the above guide shows you. After that step, you can cast a browser tab to your Chromecast television as if you had moved it to a second monitor.

Doing this is easy on Chrome. Look at the top-right of your browser window and find what looks like a Wi-Fi signal beaming toward a screen. Click this, and you’ll see all the devices that can cast your tab. Click on the one you want, and you’ll see the tab appear on the television.

Casting a browser tab via Chromecast

When it comes to Chromecast on Firefox, however, things aren’t so simple. At the time of writing, the only way to get Chromecast functionality is via a third-party application called fx_cast.

But after installing and trying it, it didn’t seem to be functioning anymore. It’s worth keeping tabs on it in case it does evolve over the coming months.

How to Cast Your Entire Desktop

Casting your desktop isn’t as intuitive as casting a tab, but it’s not difficult either.

As above, find the Chromecast icon at the top right of your browser and click it. This time, however, don’t click the screen you want to cast to; instead, click on Sources below the displays.

Then, click Cast Desktop. Once selected, you can then click the screen you want as usual.

Casting a desktop via Chromecast

If you use more than one screen, it’ll ask which one you want to cast. It’ll also ask if you’re going to cast the audio, too. Choose the options you like, then click the Share button.

Selecting a screen to cast to a TV

Your entire screen will cast to the TV via the Chromecast. This cast will include operating system elements such as the taskbar. This handy feature makes it a good option for giving demonstrations on how to perform specific actions.

Do note that you are mirroring your desktop with Chromecast and not using it to move extra open windows, open programs, and applications between your desktop and TV screen

How to Cast From a Video Service

Sometimes you want to cast a video on a webpage without casting the whole page. For example, if you’re going to put a video from YouTube through your Chromecast, you may not want the rest of the page to show—just the video.

In this situation, look for the Chromecast icon on the video player itself. You may need to hover over the video with your mouse to get the controls to appear. Then, look for the Chromecast icon and click it if you see it.

The Chromecast button on the YouTube web player

If you don’t see it, you may still be able to work around it. For example, you could try casting the tab, then making the video full screen if the player lets you do so.

How to Cast a Local Video or Music File

What if you want to cast a media file located on your computer? Thankfully, Chromecast can handle that, too.

Once you have the file ready, click on the Chromecast icon in Chrome, then click Sources. In the dropdown box that appears, click on Cast File.

Casting a file on Chromecast

You’ll see a pop-up window asking you for the file. At time of writing, Chromecast supports .ogm, .webm, .ogv, .mp4, .m4v, .opus, .flac, .webm, .weba, .wav, .ogg, .m4a, .mp3, and .oga files. This should be more than enough to support the media file you want to cast!

Selecting a file from the computer to cast

How to Cast From a Video Player

If you’re lucky, you’ll find that your favorite video player supports Chromecast natively. Apps such as VLC have adopted Google’s streaming device, allowing you to cast whatever you’re watching to the TV immediately.

If you’re using a recent version of VLC, you can cast to Chromecast by clicking on Playback, then hovering over Renderer.

Your Chromecast should appear on the list of renderers if it’s currently on and running. If it doesn’t, try restarting your computer’s Wi-Fi connection and trying again.

Setting up a Chromecast in VLC via the Playback menu

If it does appear, click on the Chromecast. Then, open the video you want to play.

It’s best to connect to the Chromecast before you play the video. During testing, I found that if VLC played a video before connecting to Chromecast, the resulting cast wouldn’t play the audio. This problem immediately fixed itself if we set the cast up first.

If you’re interested in enhancing VLC further, be sure to read about VLC’s top-secret features.

How to Cast Music and Podcasts

It’s easy to assume Chromecast is only suitable for videos, but this isn’t true. Some music apps fully support Chromecast, which allows you to turn your television into a music media center. This feature is excellent if you want to play some music around the house and have a good sound system on your TV.

For instance, you can to put your Spotify tunes on your Chromecast.

Go to the Spotify playlist page. To the right of the music progress bar, you should see a screen with a speaker in front of it.

Setting up a Chromecast in Spotify

If you’re playing music, on your PC, you’ll see your Chromecast device in the popup window when you click this icon. Click on your device, and Spotify will begin playing on your Chromecast.

If you like listening to Spotify on an Android device, why not supercharge Spotify with an Android app too?

What About Chromecast as a Real Second Monitor?

You may be wondering if it’s possible to use a Chromecast and extend your desktop to a TV as the second monitor. That is, can you set up a TV as a wireless dual monitor for your operating system and then drag windows and open apps between the PC and the television screen?

This was possible earlier. A workaround fooled Windows into believing the Chromecast was a second monitor. Unfortunately, with Windows 10, the trick no longer works. Now, it’s best to use the casting methods listed above to get the same effect as a second monitor without the benefits of extending the display.

Get the Most Out of Your Chromecast

It’s easy to assume Chromecast is only suitable for showing tabs, but it can do much more. It can display your desktop, stream video files, and even act as a music player!

If you want to extract some more fun out of your Chromecast, play these entertaining Chromecast games on your phone or tablet.
