MIT’s new UV-sensitive ink allows 3D-printed objects to change color on demand
Do you remember the color-changing dress that proved especially divisive when it made the rounds a couple years back. Was it black and blue or white and gold? The Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL) is looking to stir up a similar controversy — although this time it may be possible for the dress in question to be both black and blue and white and gold.
No, we’re not talking about any kind of “Schrödinger’s cat” thought experiment, but rather a new system called ColorFab that allows 3D printed objects to change color, courtesy of special dyes that can be activated and deactivated when exposed to different wavelengths of light.
“ With the amount of buying, consuming, and wasting that exists, we wanted to figure out a way to update materials in a more efficient way, which was largely the motivation behind this project,” MIT professor Stefanie Mueller, who led the project, told Digital Trends. “We’ve developed a system for repeatedly changing the colors of 3D-printed objects after fabrication in just over 20 minutes. Specifically, we can recolor multicolored objects using a projector model and our own 3D printable ink that changes color when exposed to UV and visible light.”
MIT CSAIL
According to Mueller, the technology could allow users to change the color of different items of clothing in order to accessorize them, or for a retail store to be able to customize its products in real time if a buyer wants to see an item in a different color. It currently takes 23 minutes to change an object’s color, but they hope it will be possible to speed up the process as the project advances. The hope is that it could one day be used like the color-changing nails in the movie Total Recall, in which a receptionist is able to change the color simply by touching her nails with her pen.
“This is just a research prototype at this point, so there are no immediate plans to commercialize,” Mueller said. “As a next step, we hope to speed up the printing process by using a more powerful light and potentially adding more light-adaptable dye to the ink. We also hope to improve the granularity of the colors so that more nuanced patterns can be printed.”
A paper describing the work has been accepted to the ACM CHI Conference on Human Factors in Computing Systems, which takes place in April in Montreal.

How to see Twitch comments through PlayStation VR

Now we can actually talk to you while streaming.
As most of you know, Twitch has become a huge part of most gamers lives. We love to share our games, and lots of folks enjoy watching. Doing this in front of a television is one thing, but when you’ve got a PlayStation VR headset on things get a little complicated. Whether its Star Trek: Bridge Crew or a Sparc workout it’s fun to watch people play, especially in VR. Until now there have been certain features lacking in the PlayStation broadcast settings for VR, the biggest being comments.
Getting started

When playing in VR in the previous PlayStation version you couldn’t see what anyone was saying to you which made the stream a little one-sided. With the latest update of the PS4 to 5.0 and the PSVR to 3.1 that has changed. You still can’t use the camera to stream yourself playing, which makes sense as the camera is busy making VR magic but you can now set the PlayStation 4 to show your messages on screen as you play. Here’s how to set it up.
Make sure you have the right software. If you are unsure head to your PS4 settings and check for the update. You should be receiving the 5.0 update and, once the 5.0 is installed and turn your PSVR on, the 3.1 update for it as well.
Step by Step
Make sure to install the 5.0 and 3.1 updates to the PS4 and PSVR.
Open the game you want to stream and press the Share button.
Check the Allow Messages button in the top left corner.
Press options again for the Advanced settings to add voice messages and set up communities.
Stream and enjoy.
Start as if you intend to stream

Load your game of choice as you normally would, in our case Sparc, and press the share button on the controller or Move Controller. This will open the standard share window, from there choose your streaming service, in this case, Twitch and move to the next screen.
From here you can see the option in the top right-hand corner to “Display Message to spectators and spectators messages.” Make sure the checkbox is selected. As you can see the video option is shaded out so you can’t select it while in VR.
Hit the Advanced Button for More Options

It’s worth heading to the advanced tab to double check all your settings. There is a checkbox that is supposed to allow the PS4 to speak the comments to you but I have yet to see this work. Make sure while you are there that all your communities are connected to your stream as well as your microphone is set up correctly.
Are you streaming?

You will now see the name of the person sending the message as well as the message itself pop up as you play the game. It really does make a huge amount of difference when you can interact with your followers and answer their questions as you play. Will you be checking messages while streaming? Are you excited about this feature? Let us know in the comments below!

Here’s how Nest Hello can out-doorbell Ring

The leading smart doorbell is about to get a huge competitor in the form of the Google-owned Nest Hello.
Ring isn’t the only company that makes a smart doorbell. It hasn’t been for a long time, actually. But the number of competitors that it’s had to deal with have been few and far between. And for the most part, almost no one has come out with anything that looks remotely acceptable as a way to greet a stranger at your home. (If I had to answer, I’d say it’s the Ring Pro, then the SkyBell Trim, in that order. And that’s it.)
In a month or so, though — Nest Hello is slated for release in February 2018, and I’d look for it in the latter part of the month — that’s going to change in a big way.
I admit I’d completely forgotten about Nest Hello. Announced back in September 2017, it’s Nest’s take on the venerable ding-dong button. And just like it did with the simple home thermostat and smoke detector before it, Nest Hello not just has the opportunity to make your front door a whole lot smarter — it’s going to look really good while it’s doing it.
Ring has done wonders for my peace of mind for the past few years, particularly as I was traveling a lot. I can’t overstate that. But Nest Hello has me excited in a new way, because I think it’ll do many of the same things even better.
Ring Pro and Nest Hello are priced similarly — with the former $249, and the latter $20 less. So here are the things I, as a longtime user of a Ring Doorbell — I’ve used the original Ring, Ring 2 and Ring Pro — will be looking for when Nest Hello is released next month.
See at Nest
A better camera
Nest Hello is surprisingly coy about the resolution of its camera. It doesn’t list the resolution in any of its top-level promotions on the Nest website.
Normally that would worry the hell out of me. If it doesn’t say 1080p, chances are it’s only 720p. A higher resolution is almost always better, of course, and 1080p is what you find in current top-shelf products like the Ring Pro.
And it turns out Nest Hello isn’t 1080p. It’s actually using a 1600×1200 resolution. While that’s actually fewer total pixels than a 1080p camera (1.9 megapixels versus 2.1 megapixels), Nest says there’s good reason for that.
1080p cameras have a wider view with extra horizontal space that’s great for keeping an eye on a large area. But the view isn’t as good for seeing visitors head to toe from a lower angle. UXGA gives you the expanded vertical view that you need in order to see someone standing right in front of the camera as well as packages on the ground.
Fair enough, and there’s definitely room to improve on the image quality we’ve had with Ring.
No, really — who’s there?
These smart doorbells show you someone is there just fine. But Nest promises to actually be able to tell who is at your door.
Nest currently has “Familiar Face Alerts” available with its top-end Nest IQ cameras. It’s bringing that same tech to Nest Hello. You’ll need a Nest Aware subscription for that, which is $100 a year for the first camera in your home, and $50 a year on top of that for every additional camera, and that’s for the 10 days of video history. The 30-day plan takes things up to $300 and $250, respectively. (I’d really love to see Nest consolidate that into a one-size-fits-all plan, and it’s gotta come down on that price a bit.)
Once you’ve ponied up the cash you’ll be able to teach Nest whose face belongs to whom, to better suss out the, well, familiar faces from those you really want to worry about.
Nobody else does that.
Smarter notifications
I love that my Ring Doorbell notifies me when it sees motion, so I get an alert before someone even makes it to the door.
I hate that my Ring Doorbell notifies me when it sees motion over and over again when my kids are playing in the yard, or when I’m doing yard work. It’s kind of dumb like that. It’s *just now* rolling out fixes for this, but I’ll have to wait and see how well it works before rendering a verdict.
In any case, one of the best things Nest’s suite of products can do is actually recognize when you’re home, and when you’re away, thus giving all of its products a general “Home” or “Away” status.
This is guesswork on my part, but I’d be willing to bet that you can tailor notifications for when you’re home versus when you’re away. Sure, I like to see who’s coming when even when I’m home. But there has to be a smarter way of going about this. Fewer notifications when I’m at my house. More when I’m away.
Better software
I’ve used a lot of connected home equipment and services. It’s pretty easy to tell which has a more native “feel” to it, and which is more like a web service all wrapped up in an app, with the lag to go along with it.
That’s something Nest does as well as anyone, and definitely better than Ring. If you’ve used Nest’s thermostat before, you’ll immediately know what I’m talking about — especially if you’ve also used a janky web interface for some other thermostat. (I’m gritting my teeth at my own electric utility here.) Same goes for Nest’s cameras. Scrubbing through a timeline is akin to video editing software — not some clunky web player.
That’s not to knock Ring. It’s come a long way the past few years, and its software continues to improve. But Nest is just in another class.
Canned responses are quick, and canned
At launch, Nest Hello is going to come with three “Quick Responses,” so you can reply with a quick touch on your screen instead of actually having to talk.
It’s like quick replies to incoming phone calls, and it’s going to be a welcome addition.
What else I’ll be looking for
A few more quick hits of things I’ll want to see, or that I’m worried about not seeing.
- Doorbells are small. It’s hard to cram a lot of electronics in there, and there’s not a lot of power to work within low-voltage wiring. Nest Doorbells have been a little finicky when it comes to Wifi strength — and that pretty much affects everything. Hopefully Nest Hello will impress here.
- Ring has these cool little “Chimes” that connect to your network and plug into an outlet, so you can hear the doorbell from anywhere in your home. That’s great for a large home. And its Chime Pro acts as a network extender for Ring products. Nest, at least for now, doesn’t have anything like this.
- Back to the low-voltage wiring for a second. Like the Ring Pro, you’ll need to make sure you have a low-voltage transformer that can put out enough juice. (I actually had to upgrade mine for the Ring Pro.) This is something a homeowner can probably do without professional help. But if not, there’s the whole “Nest Pro” thing.
- A reminder that Google’s coming out with a slew of “smart displays” — some named exactly that, others with more awful product names — this summer, and they’ll work hand-in-hand with Nest products.
Nest Hello is available for preorder now and ships in February.

T-Mobile will use 100% renewable electricity by 2021
T-Mobile is expected to save $100 million in energy costs over the next 15 years.
T-Mobile often markets itself as the Un-Carrier in the United States, and now the company is aiming to position itself as the Un-Non-Renewable Electricity User. Bad jokes aside, T-Mobile just announced that it’ll be joining the RE100 initiative to start using 100% renewable energy sources.

The Un-Carrier’s current goal is to move to 100% renewable electricity by 2021, and as a result of this, it’s estimated that T-Mobile will cut down its total energy costs by $100 million over the next 15 years. Per CEO John Legere:
It’s the Un-carrier way to do the right thing by our customers, and moving to renewable energy is just a natural part of that.
To kick this new initiative off, T-Mobile finalized a contract with Infinity Renewables’ Solomon Forks Wind Project for 160 MWs worth of renewable energy that’ll start generating power for the carrier at some point in early 2019. T-Mobile’s first use of wind-powered electricity occurred this past December when it made a deal with Red Forks Wind Power. Combining these two deals together, T-Mobile already has plans to generate 320 MWs of power – enough to sustain 60% of the company’s nationwide energy use.
Commenting on this announcement, RE100 Head Sam Kimmins said:
It’s great to see T-Mobile US shifting to renewables for its power consumption. As a large electricity consumer in the US, they can truly transform energy systems by bringing significant renewable capacity online – all of that while delivering real value to their customers. I congratulate them for a great commitment.
T-Mobile offers free data and calls in South Korea during the 2018 Olympics

How to get started with Spotify

Move over iTunes – Spotify is now the first name in music.
Spotify has been around for 9 years now, and for at least the last five, the service has fairly well dominated the music subscription scene. Apart from being the first real name in music streaming, Spotify’s real claims to fame are how easy it is to use and how their student subscription lured in millions of young subscribers that stuck around long after their discount vanished.
Whether you’re finally moving from CDs to a streaming library or you’re considering jumping to Spotify from another service, here’s what you need to know about joining and using Spotify.
Joining is as easy as clicking the Facebook icon

Joining Spotify for most users is as simple as hitting the “Sign Up With Facebook” button, which will connect to your Facebook account and pull in your name, email, and birthday. Should you not have a Facebook or wish to keep the two separate, you can enter your email, name, birthday, and desired password manually, you barbarian.
You then click the captcha to ensure that you aren’t a robot — you’re not a robot, right? — and you’re instantly taken to the main page of the Spotify web interface, where you can click on one of the featured stations or start browsing to your heart’s content. There are a variety of stations and mixes displayed on the tabs of the main page, but if you’ve already got a hankering for something specific, you can search for it and get your groove on.
Start establishing your music history



There’s a lot you can do when you start with Spotify, but I suggest searching for some of your favorite songs or artists and starting your music history off with what you listen to the most. This will also give you a chance to ease yourself into Spotify’s layout by searching for albums and songs you like as opposed to leaving yourself and your music history at the mercy of what you can find browsing.
Your music history is very important in Spotify, as it’s what the service will base your weekly “Discover” selection on, as well as your periodic listening statistics. Keep this in mind before you use Spotify to appease your niece and nephews demands to listen to the Moana soundtrack a billion times.
While on a Free account, keep in mind that everything you play on the app will be stuck on Shuffle, and the playing queue you see will not be the actual order the songs play in. You also won’t be able to skip to a particular song, and you are limited to six skips an hour. Use them wisely.
Use the web app for the heavy lifting

While you’re on a Spotify Free account, the web app is going to offer a superior experience to the Android, as you are stuck on Shuffle Play on the mobile app until you upgrade to Premium. The web app also allows you to see more search results at a time and seems to play ads a tad less frequently, so use the web app on your desktop or Chromebook while you’re building up a playlist or doing a lot of library management.
There will be ads



Ads are part of the free experience. Spotify has to make their money somehow. While using Spotify Free, a couple ads play every 4-8 songs, though tend to get repetitive. I’ve been listening to a Disney shuffle and have heard the same Walmart grocery pickup ad 5 times in 45 minutes. Oh, and whoever thought these “unexpected” Geico ads were a good idea needs to be locked in a room listening to them “it’s a small world”-style for a few days.
Especially the beatboxing one.
If you want to forgo the ads, as well as Free’s other limitations, you’ll want to consider one of Spotify’s premium plans.
Where do we go from here?

Once you’ve got a few playlists under your belt and you’ve started building up your library and history, the sky’s the limit. You can start sharing your playlists with friends, start digging into stations to find your new favorite songs, or you can rediscover your old favorites again while recreating your old CD library. Speaking of your old library…
How do I upload my music to Spotify?
The short answer here is you don’t. I’m sorry.
Spotify’s just not built around a personal music locker like Google Play Music, Amazon Music and iTunes/Apple Music are. There are ways to use Spotify to combine music you have downloaded on your computer using Spotify’s local files feature, but it’s not especially friendly, it doesn’t carry from device to device, and for most of us, it’s just not worth the hassle.
Kiss your CD-buying days goodbye.
Pick a weekend, a bottle of your preferred stress-relieving elixir, and just replicate your library yourself with Spotify search. It’s a natural time to prune your library, anyway.

Moto X4 with 6GB RAM launches in India on February 1 for ₹24,999
Unfortunately, there’s no word on availability in other markets.
The Moto X4 may be a very different phone compared to past entries in the X-series, but even so, it’s one of the best mid-range Android phones on the market right now. The X4 has been available in India through Flipkart for a few months now, but a new version with 6GB of RAM is right around the corner.

One of Andrew’s biggest complaints with the Moto X4, when he reviewed it in October, was its sometimes slow performance. The X4 isn’t a slouch in its current form, but the limited 3GB of RAM “means you’re just a bit more likely to see apps dump out of memory than on other phones with 1-3GB more.”
This new version of the Moto X4 with 6GB of RAM is launching in India through Flipkart once again on February 1, and it’ll set you back ₹24,999. That’s expectedly more expensive than the 3GB RAM model which costs ₹20,999, but for that much more RAM, that’s not a bad deal.
You’ll also get upgraded storage from 32GB up to 64GB, but everything else about the Moto X4 remains the same. It’s unclear if/when this model of the phone will make its way to markets outside of India, but you sure wouldn’t find me complaining if it does.

Apple settles with Immersion over haptic feedback licensing
In 2016, haptic technology company Immersion filed two rounds of lawsuits against Apple. Both alleged that the tech giant had infringed upon some of Immersion’s patents with the first focusing on the iPhone 6, 6 Plus, 6s and 6s Plus as well as Watch, Watch Sport and Watch Edition. The second added the MacBook and MacBook Pro lines to its complaint. Immersion also filed a complaint with the US International Trade Commission (ITC), which launched an investigation into the alleged patent violations a few months later. But the saga may be nearing an end because today, Immersion announced that the two companies have reached a settlement.
Immersion says that the settlement terms are confidential and we therefore don’t have a lot of details about what the agreement gets either company. Immersion does say that it’s a global settlement, so it’s likely, whatever the agreement is, it will apply to both companies’ ventures both in and outside of the US. Apple has agreed to license some of Immersion’s technology, according to the announcement, but it’s unclear if all of the patents named in the two lawsuits are a part of that licensing agreement. It’s also unclear if the two suits and the ITC complaint will be wiped away, but it seems unlikely that Apple would enter such an agreement without that being a stipulation.
Apple is certainly not the only company to be targeted by Immersion. The firm has previously brought lawsuits against Microsoft, Sony and Google, to name a few.

BMW takes full ownership of DriveNow’s car sharing service (updated)
BMW has been synonymous with DriveNow’s car sharing service for several years, and today it’s cementing that commitmen. The German auto brand has taken full ownership of DriveNow by acquiring Sixt’s stake in the company. This gives BMW “all options” for mobility services in the future — it’s free to take the tech-savvy rental platform in whichever direction it likes. For now, business will continue as usual with DriveNow acting as a BMW subsidiary.
We’ve asked how this will affect ReachNow, DriveNow’s North American equivalent, and will let you know what BMW can say.
The acquisition comes hot on the heels of BMW’s buyout of Parkmobile (which it also had a stake in), and creates a clearer picture of the automaker’s overall strategy: it wants to offer services that cover every aspect of driving, whether it’s renting a car in a hurry or finding a place to park while you shop. Like its rivals, BMW is preparing for the decline of car ownership as people shift to on-demand rentals, ridesharing and (eventually) self-driving cars. DriveNow not only gives BMW a source of income in those conditions, but guarantees a reliable destination for its vehicles.
Update: BMW tells us that this doesn’t affect ReachNow.

White House says it’s not considering a national 5G network
Yesterday, Axios reported that the Trump administration was considering the option of a government-controlled 5G network. Documents obtained by Axios showed that Trump’s national security team had proposed a couple of options, including one where the US government funds and constructs a single network, aimed at protecting US networks from Chinese cyberattacks. However, Recode now reports that those documents were outdated and their proposed plans are not actively being considered by the administration.
Recode’s White House sources said that not only was the document old, it was also not any sort of serious proposal on the National Security Council’s part. The idea had been put out there by a staff member, but was not part of any major upcoming policy shifts and likely never would be.
Today, FCC Chair Ajit Pai released a statement opposing such an idea saying, “The main lesson to draw from the wireless sector’s development over the past three decades — including American leadership in 4G — is that the market, not government, is best positioned to drive innovation and investment.” Pai added, “Any federal effort to construct a nationalized 5G network would be a costly and counterproductive distraction from the policies we need to help the United States win the 5G future.”

UK to fine companies up to £17 million for cybersecurity lapses
The UK government will fine companies in “critical industries” up to £17 million if they have woefully inadequate cybersecurity defences. The penalty system is a response to an EU directive, passed in August 2016, that was drawn up to ensure its member states are prepared for modern cyber attacks. Known as the NIS directive, it will be transplanted into UK law to protect health, energy, transport and digital infrastructure. The fines will be a “last resort,” however, and take into account how co-operative the company has been with their relevant regulator, the actions taken to remedy the situation, and any other law that might have been breached.
The UK government consulted on its plans to introduce the fee system in August and September last year. It will apply to “operators of essential services,” a term that varies depending on the industry. In the transport sector, for instance, it includes airport operators and harbour authorities with more than 10 million annual passengers. The category can also apply to mainline railway operators, large passenger and freight water transport companies, and international rail services. In the “digital” realm, it covers Top Level Domain (TLD) name registries, Domain Name Services (DNS) service providers and Internet Exchange Point (IXP) operators.
Operators of essential services (OES) will need to report cybersecurity incidents above a yet to be determined threshold to their relevant Competent Authority (CA). These government-appointed regulators vary by industry: Ofcom will handle digital infrastructure, for instance, while the Secretary of State for Environment, Food and Rural Affairs (Defra) — supported by the Drinking Water Inspectorate — will deal with water supply and distribution. “Digital Service Providers,” which include search engines, online marketplaces and cloud computing services, will need to report similar instances to the Information Commissioner’s Office (ICO). It’s not clear, however, if they fall under the same fee system as OES.
“The Government can reassure Digital Service Providers that both it, and the Competent Authority will approach implementation of the NIS Directive in a reasonable fashion,” the government said in a consultation document last weekend. “Companies will be given time to implement the requirements of the Directive.” Guidance on the NIS Directive has been released by the National Cyber Security Centre. The rules come into effect on May 10th and will, the government hopes, minimise the next WannaCry and persuade companies to keep up with best cybersecurity practices.
