19 Things Tried And Liked In 2017

All the innovations, apps, hacks, habits, gadgets, and robovacuums that made our lives a little better this year.

A few months ago, my girlfriend bought us a Roomba. Well not a Roomba, but the Deebot N79, the robot vacuum that the Wirecutter recommends. My fantasy was that it would be my dog's best friend. I imagined King, who is a 20-pound dachshund mix, going for rides on the Deebot around our small apartment, napping next to it as it charged, and nosing it away from hazards. Instead, when we turned the machine on for the first time, King barked at it and ran away. Alas.
What the Deebot is very good for is sucking up King's fur, which is short and black and gets freaking everywhere. We run it a few times a week, it rarely gets stuck, and while it occasionally forms strange obsessions with certain hyperspecific locations in our bedroom, like a deranged Ouija planchette, most often it gets the job done. This has made my girlfriend less ornery and me less defensive. It has had no effect on my dog. Still, tech in 2017 that makes life a little bit better instead of cataclysmically worse: What a relief!

2. Freedrum


When I was 12, I asked for a drum kit for Christmas. I didn't get it. Instead, my parents gave me a small rubber pad about the size of a Pop-Tart and a pair of drumsticks that looked like they'd been borrowed from a Fisher-Price Laugh & Learn Drum. It was a ferocious disappointment. The next day I destroyed my sad little kit Keith Moon–style as a finale to a bootlegged version of the Who's "Won't Get Fooled Again." I've been a frustrated drummer ever since. Which is why Freedrum is among the best things that happened to me this past year, and easily my favorite tech of 2017. It's an invisible drum kit, and it is fucking awesome. With four wireless sensors — one on each drumstick and one on each foot — it realistically emulates a seven-piece drum kit. It does it with pretty much imperceptible latency. Now, hitting the air is obviously not nearly as fun as hitting the skins, but for those of us who've been air-drumming with imaginary drums for years, it is plenty fun; certainly, it beats banging on a toilet paper box in your basement.

3. PopSocket


Whenever people see my glorious PopSocket, they have the exact same list of questions. So I will answer them for you:
What is that?
Thanks for asking! It’s a PopSocket, my friend. It sticks onto your phone case and makes it easier to hold.
Why do you have it?
At the end of 2016, I got an iPhone 7 Plus (the big one) because I wanted the portrait mode camera. I actually grew to like the bigger size, especially for reading articles or watching videos. But I did find it slightly more difficult to hold.
The PopSocket makes holding a big phone much more secure — I never worry about dropping it while holding the subway pole or onto my face while using it in bed. Best of all, it eliminates finger cramping and “smartphone pinkie.” Your hands don’t hurt from using your phone for hours on end all day long!
Plus, you can use it as a stand to prop up your phone and watch videos (to be honest I don’t do this often, but it’s cool).
But how do you put it in your back pocket?
Don’t worry! It pops back down flat. See?
Hmm that’s not totally flat, does it fit in your pocket like that?
My dude, how tight are you pants? It’s like half a centimeter, it definitely still fits in my pockets. Seriously, it’s not an issue.
Where can I get one?
You have to order directly from the company's website, PopSocket.com.
Isn’t it annoying that you can’t type on the phone while it’s lying down flat on the table?
A little bit. Sure, there are some downsides to the PopSocket. But the benefits far outweigh the negatives. Treat yourself. Your fingers deserve a break. Get the PopSocket. Just trust me.

4. Ativan

If there was one tech product I couldn't live without in 2017, it was Ativan.
When you wake up in the morning in California, Trump has already been awake for four or more hours, tweeting, and the news is in *full effect.* And in the year of our Lord 2017, the news is never, ever good.
Nazis on Twitter! Russians on Facebook! Terrorists in Times Square! Men behaving horribly, everywhere! Good God, we're moving our embassy to Jerusalem? Well I'm sure that will go great... 2017 is basically one long, anxiety-inducing, pertinacious breaking news event.
There was this moment in August, when I was sitting in the Amtrak station with my wife as we prepared to set off for a week in the mountains, when we watched a bellicose Trump on cable TV, saying of North Korea that maybe he wasn't harsh enough. And it just nearly fucking broke me. I'm a Gen X'er who grew up on The Day After and On the Beach and Alas, Babylon. Not long before that speech, I'd been in Seattle, where the newspaper had a picture of North Korean nukes on the front page. In San Francisco, the parlor game du jour is calculating whether or not you have enough time to get across the Bay Bridge and over the hills after a launch is detected but before impact. (Spoiler: No one does.) Shit is existential on the West Coast. I watched Trump on TV, looked out the window at the robin's-egg blue sky, and imagined as intently as I could what an inbound missile would look like. This was not a healthy thought.
And so we're all dealing, in whatever ways we can. For example, my wife gave me two days alone in a cabin in the woods to chill out and think and relax. No phone. No internet. No TV. No nothing but me and my thoughts. And so I basically spent 48 hours having a massive anxiety attack, then came home and bought a 9 mm handgun, and a fuckton of hollow-point bullets.
I used to have a lot more faith in society's ability to come together in the face of a crisis. But that was in, like, 2015.
And of course the handgun didn't help. At all. But what did was a trip to see my doctor, who put me on anti-anxiety medication. And, boy, has that been nice. Ativan can grab you by the collar and shake you and tell you that it's going to be okay, man, even if just for the next couple of hours. We focus so much on hardware and software. But modern medicine is amazing; the things it can do to your brain are amazing. And we're just getting started.
Sometimes I fantasize about having a bunker, and land far from a major city, with well-water drawn up deep from the earth. I think about fishing and trapping and raising livestock. Grain stores for the year to come. It seems like a nice life, in the post-apocalypse, if you do it right. In the meantime, there is Ativan.

5. Airpods


The best gadgets are the ones you use the most but think about the least, because they just get out of the way — and Apple’s AirPods, which I’ve jammed into my ears pretty much all day every day since February, when I got them, are a great gadget. They look like my iPhone earbuds melted down my ears, they sound…OKish, and they’re still the reason why people stare at me in public (I think). But god do I love them. You pop them into your ears, and hit the play button on your iPhone, Apple Watch, MacBook or iPad and…that’s it. You pop one out to pause playback. And when they do run out of battery, you juice them up by letting them sit in that smooth AF case for just a few minutes.
They’re also seemingly invincible: I’ve worn them in the shower (don’t try this at home), in the gym, on the treadmill, in a standing room-only train compartment, and on a motorbike zooming down a highway at 50 mph, and they’ve never stopped working or fallen out. If this is how magical Apple’s first ear-puters are, imagine how they will be a few years down the road. My ears are ready.

6. Dockless bike-sharing

I ran into dockless bike share in Berlin this summer, where at first I marveled at how trusting people were to just leave their rented bikes at the entrances to parks and on street corners. My son then downloaded the NextBike app and found us a pair of bikes a block away, which we left a short cab ride from the airport. When I got back to New York, CitiBike seemed incredibly clumsy — the equivalent of a phone that plugs into the wall.

7. Sporcle


All things considered, 2017 was a pretty great year for me.
Just kidding, it fucking blew! My job thrust me into the anxious, sweaty center of an unceasingly bonkers news cycle. I took on the kind of debt that keeps a person up at night. A close family member got cancer. I slept less and drank more than I ever have before. I started dreaming about nuclear war.
And when it all became too much, I’d grant myself the gift of 15 uninterrupted minutes for a geography quiz on the trivia site Sporcle — mostly countries of the world, but I fuck with flagscapitals, and the United States as well. This meant 15 minutes when I couldn’t think about anything but the task in front of me, when North Korea was just one of 197 country names to retain and regurgitate, when my biggest challenge was remembering where East Timor is, and when finally doing so after like 400 tries could fill me with a pure, dumb joy that was otherwise pretty hard to find in 2017. Clicking around a pixelated world map, typing into a tiny box, letting rote memory take over: It’s the closest I’ve ever gotten to meditating. And now I know where East Timor is!

8. The Apple Watch

Two weeks before Thanksgiving last year, my dad was driving me to the airport. As I got out of the car and walked around to say goodbye, he passed out in the driver’s seat. It was cardiac arrest and, like many heart failures, it came out of nowhere. My dad was saved that day by a few quick-thinking people, including an ER doctor who happened to be exiting the terminal at that exact time, but there have been plenty of issues since, and over the last 12 months, he’s been in and out of the operating room.
A few days after being released the first time, he was terrified it would happen again. He confined himself to an armchair in our living room and tried to do very little. He said he was recovering, but after a certain point, it wasn’t just that.
So for Christmas last year, my brother and I brought him an Apple Watch. It was a pretty thoughtless decision — we were perusing the aisles of Target on the 24th without a clue of what to get a hard-to-please man — but we were drawn in by the device’s heart rate monitor. So we pulled the trigger. Dad opened it on Christmas Day, showing little interest in the thing before putting it aside to sit back down in his armchair.
When I came back to visit every so often, I noticed that he began wearing it. And then one day he showed me his heart rate. Dad was walking outside again and playing with the dog, and he wouldn’t go anywhere without that damn watch. He loved being able to monitor his heart in real time, and that freed his mind to focus on other things. A 63-year-old man’s security blanket.
It feels odd writing that technology can “comfort” people, but for my dad, a $200 device did just that. The watch didn’t keep him out of hospitals and it didn't make him healthy, but it did give him the ability to stop worrying.
Apple’s new Series 3 watch is testing the ability to monitor users’ hearts and track arrhythmias, the abnormal rhythms that can signal impending heart failures. If those tests prove the device works, a lot of folks could avoid, or at least better prepare for, what happened to my dad. Those people may never have to worry, and fewer of them will have to spend their weeks inside emergency rooms. That’s comforting.

9. MoviePass

Halfway into Murder on the Orient Express, I realized I was watching a pretty boring and unnecessary adaptation of one of my favorite Agatha Christie novels. Normally I would’ve been annoyed that I’d paid to see this in a theater, since the price of admission is higher than ever. But MoviePass erases all those worries by letting you watch unlimited movies in 4,000 participating theaters for just $9.99 a month. (OK, you can’t watch 3D movies, buy tickets a day in advance, or watch more than one film a day. But otherwise, unlimited!)
You pick a showing on the MoviePass app while standing in the theater, and a physical card autoloads with money that you use to buy a ticket. Clunky, yes, but it pays for itself with just one movie a month. “How does this company stay in business?” you may ask. Honestly, it’s unclear: MoviePass has in the past cost much more, from $14.95 to nearly $50, and executives say they plan to make money by selling users’ data. Who knows how long this will last — so get in while you can.

10. AllTrails

My favorite app of the year delivered me out of range of cell service. The day after I finished covering the special election in Montana — the one where Greg Gianforte allegedly body-slammed a reporter and won anyway — I had to get away from push alerts. But I’m also trash with directions and didn’t know the area. AllTrails, which helps you find nearby hiking trails and download maps of them, brought me to a hike out of cell range that turned out to be breathtaking, ass-kicking, and just what I needed to decompress. AllTrails is my anti-Twitter: restorative in a year when technology felt addictive, aggressive, and draining.

11. iOS’s artificially intelligent “Memories”

I don’t love Apple’s algorithmically generated “Memories” videos — which set curated photos and videos from my camera roll to music — because they’re good. In fact, I kind of like them because of how bad they are.
It was only in the last year that I started getting push alerts from my Photos app, telling me there was a new Memory ready for me to view. These Memories, for those who aren’t iPhone users or wisely choose to ignore their phone’s Black MIrror-esque salutations, are framed around a date or a place where you took a lot of pictures, or a person of whom you take a lot of pictures. So, for example, when I took my dad on a trip to Point Reyes National Seashore, my iPhone made me a Memory called “At The Beach.” It also made one called “Together” that is exclusively pictures of me and my boyfriend. Creepy.
But the thing about these videos is that, while they are cool in an oh-my-god-how-does-it-know way, they are not actually cool. At best, they aspire to the kind of nostalgic schmaltz typically associated with a slideshow prepared for retirement party or fiftieth wedding anniversary. But the execution is typically closer to the expected output of a high school iMovie video editing class.
For example, the Memory called “Home” that dates to December 25, 2016 includes some heart warming photos of my stepdad in an oversize bathrobe and my mom hugging Santa, but also many, many nearly identical selfies that I apparently sent to friends and loved ones on Christmas Day. The Memory called “Longmont,” which is where my boyfriend’s sister got married in August, contains photographs of my sister and her boyfriend, neither of whom live in this country, because I received WhatsApp photos of them the same day as the wedding that were automatically saved to my photo roll. There’s also nothing stopping your phone from interpreting, say, a last minute trip to attend the funeral of a loved one as a fun vacation, or from incorporating anything from the banal to the explicit in an otherwise charming slideshow from Valentine’s Day.
But in their inaccuracy and uncanniness, my artificially aided Memories are endlessly entertaining. I can set photos of my friend’s summer wedding in a Boulder park to club music; I can send my mom a cloyingly deranged montage of photographs of myself when she asks me how I’m doing. There’s some comfort in the knowledge that, as advanced and intelligent as the machines have become, they still aren’t people. They don’t own my memories. They aren’t anywhere close.

12. EC Tech External Battery

My iPhone’s internal battery is my least favorite tech of the year. The 6s I had from January to March would die whenever the temperature dropped below 60 degrees, no matter how charged the phone actually was. The phone I have now isn’t much better, because iOS 11 drains it like a sewer and because I use the damn thing more than ever. By noon every day I’m out of juice. So my massive EC Tech battery has become less of an accessory than a new permanent limb of my phone. I check for the battery every morning when I make sure I have my wallet, phone, and keys. It’s saved me in hundreds of situations, both dire (filming at a violent protest) and casual (getting directions home from a bar I’ve never been to). A dead phone makes me panic, and I resent that I’m so dependent on it, but I do savor the relief an on-hand external battery can give.

13. Bitcoin

Early this fall I decided — on a whim — to buy a little bit of bitcoin. It was on a tear when I found myself on Coinbase, the bitcoin marketplace where any rube with a bank account can purchase some of the enigmatic digital currency. Despite the sinking feeling that I was likely coming in at the peak of some kind of bubble — and the fact that I possess hardly any knowledge of financial markets, currency trading, or bitcoin itself — I was too fascinated by the phenomenon not to put a little skin in the game myself.
I bought just enough for it to feel meaningful — an amount small enough that I'd be just fine losing it all, but large enough to give the investment some actual stakes. And then I sat back and did...nothing as bitcoin's price climbed steadily, then rapidly. My modest investment has now more than doubled, which rules and — should this batshit run continue at a similar pace, which it most assuredly won't — I'll be well on my way to purchasing my first blogger's yacht.
And while making some money off mysterious market forces I don't fully understand is exciting and all, it's not what I love about dipping my toe into cryptocurrency's murky waters. By throwing some of my own cash into bitcoin, I gave myself a reason to care — even if just a little — about the phenomenon. After refreshing Coinbase's app during idle moments, I'll inevitably end up doing some reading to try to wrap my head around bitcoin's meteoric rise. My investment has led me to peruse semi-obscure yet impressive publications like Coindesk; read and poke fun at a slew of obsessive analysts and overzealous analysts and blockchain evangelists; and watch as smart financial humans and outlets are forced to confront bitcoin and all its questions. Why is the price soaring through the roof? Is this a bubble? How much of a bubble is it? What happens if you become a bitcoin billionaire? When am I going to lose everything?
I often think the best way to report on new and obscure technology is to throw yourself into it in an exaggerated way. By jumping in aggressively or taking a piece of technology to the furthest extreme, often you get a better sense of the benefits, shortcomings, and limitations of that thing. And while I wouldn't call my investment in bitcoin extreme by any measure, it's forced me to care more than I ever would have. And the new yacht doesn't hurt either.

14. Nature sounds and noise-canceling headphones


2017 was a lot. My anxiety, my attention span, my productivity all took a turn for the worse this year. Between the threat of nuclear war, etc. and the challenges of an open office, there was no chance I was getting any work done. So I bought myself a really nice pair of noise-canceling headphones (the Bose QC35 35s) — but often, they weren’t enough. I can’t listen to music while I write, so I turned to nature albums by anonymous sound artists on Spotify. I’ve listened to many, many hours of this stuff, and rain — specifically this album, titled Calming Rain Sound — is my favorite. Spotify also has a decent, recently compiled Rain Sounds “mood” playlist.
And on days where I need to turn my focus up to 11, I use Noisli, a web app that lets you mix and match different ambient noises. I work best to a little wind, plus fire crackle.
Tuning out the world and listening to the sound of water gently dropping from the sky can be so comforting in these dark times. Try it!!

15. My robovacuum cleaner, the Eufy RoboVac 11


This morning, I woke up to the sound of my cat knocking a water glass off my kitchen table, shattering it into a million pieces. (I was not pleased with Laser Beam, who is now definitely going to be shipped off to boarding school for this transgression.) It was the day after our office holiday party and I was hungover, already an hour behind schedule due to my hitting the snooze button 10 times that morning, and had a mess of glass shards to clean up. Most people would be in a pretty bad mood at this point, but I had Eufy.
Yeah, yeah, I know that robovacuum cleaners are expensive. I know they can get stuck under the refrigerator and in weird corners, so it’s not totally hands-off. But if your tech philosophy is to just let gadgets enable your laziness and have less in life to do — as mine is — then I highly recommend the robovacuum cleaner.
It’s also doubly convenient for picking up pet hair off the floor, and it’s fun to drive it around with a stuffed animal riding on top, and confuse the living daylights out of your cats.

16. @OldTakesExposed

Twitter is a platform meant for predicting the future and getting it horribly wrong, among other uses. But for far too long, people who tweeted absolutely, bafflingly inaccurate hot takes had no place that would highlight their work. That's where @OldtTakesExposed comes in. The account regularly retweets predictions gone wrong, often months after the fact. You'll like it if you like bad sports predictions being held to account and other life-comes-at-you-fast moments. @OldTakesExposed is a rare ray of light in a pool of Twitter darkness. It's a glorious shrine to takes that age like roast beef left out of the fridge for weeks. It's exactly what we all need.

17. Signal

Hackers, reporters, and people who think the word "encrypted" sounds cool were using Signal to send secure messages before Trump was elected, no question. But afterward, even regular people started looking for more secure options. Signal makes it possible (or so we hope!) to talk to people who want to protect their identities without having to, you know, call them. Which is great for millennials. But now, a lot of my friends have Signal set as their default messaging app, which means the bulk of their communications are encrypted. Signal makes people feel safe, which means they feel comfortable, which means they open up to you — and that’s a great thing.

18. Canva

I couldn't tell you how to use layers in Photoshop or even really how to use Photoshop at all, and I've worked in digital media for over 10 years. This is embarrassing! But sometimes you just want to be able to put some text on an image collage and not have to stress about it! And then someone told me about Canva and my life hasn't been the same. Canva — which launched in the summer of 2016 — is an Australian design app and website that allows even the most design-challenged among us (ahem, me) to make images that actually look presentable. The app has templates for a variety of different social media posts — including Instagram (and a separate one for Stories), Pinterest, a Twitter header, and Snapchat Geofilter — as well as more general designs like logos, posters, flyers, invitations, and even album covers. No one's going to mistake my Canva designs for fine art, but for my purposes, they're more than enough.


19. The Joule sous vide machine

File this away in: “buying only the gadgets that enable your doing as little as humanly possible.” The Joule was one of my pricier purchases last year, but also one of my most used ones. Like, pretty much every day kind of use.
For the uninitiated, sous vide gadgets heat up a pot of water to a very precise temperature, and hold it there. That means you can cook fairly tricky food, like steak, which I now cook at least once a week, perfectly — every single time. You just season the meat with a little salt and pepper, add herbs, plop it into a gallon-size ziplock bag, and sprinkle in a dash of olive oil. Cook times are about an hour or so. Theoretically, that gives me enough time to go for a run or do something active while waiting for my food to finish cooking, but usually I just lean into the laziness by watching an hourlong episode of whatever’s on my TV at the time. But hey, doing nothing: mission accomplished, again.


New depth sensors could be sensitive enough for self-driving cars

Computational method improves the resolution of time-of-flight depth sensors 1,000-fold.

For the past 10 years, the Camera Culture group at MIT’s Media Lab has been developing innovative imaging systems — from a camera that can see around corners to one that can read text in closed books — by using “time of flight,” an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor.
In a new paper appearing in IEEE Access, members of the Camera Culture group present a new approach to time-of-flight imaging that increases its depth resolution 1,000-fold. That’s the type of resolution that could make self-driving cars practical.
The new approach could also enable accurate distance measurements through fog, which has proven to be a major obstacle to the development of self-driving cars.
At a range of 2 meters, existing time-of-flight systems have a depth resolution of about a centimeter. That’s good enough for the assisted-parking and collision-detection systems on today’s cars.
But as Achuta Kadambi, a  joint PhD student in electrical engineering and computer science and media arts and sciences and first author on the paper, explains, “As you increase the range, your resolution goes down exponentially. Let’s say you have a long-range scenario, and you want your car to detect an object further away so it can make a fast update decision. You may have started at 1 centimeter, but now you’re back down to [a resolution of] a foot or even 5 feet. And if you make a mistake, it could lead to loss of life.”
At distances of 2 meters, the MIT researchers’ system, by contrast, has a depth resolution of 3 micrometers. Kadambi also conducted tests in which he sent a light signal through 500 meters of optical fiber with regularly spaced filters along its length, to simulate the power falloff incurred over longer distances, before feeding it to his system. Those tests suggest that at a range of 500 meters, the MIT system should still achieve a depth resolution of only a centimeter.
Kadambi is joined on the paper by his thesis advisor, Ramesh Raskar, an associate professor of media arts and sciences and head of the Camera Culture group.
Slow uptake
With time-of-flight imaging, a short burst of light is fired into a scene, and a camera measures the time it takes to return, which indicates the distance of the object that reflected it. The longer the light burst, the more ambiguous the measurement of how far it’s traveled. So light-burst length is one of the factors that determines system resolution.
The other factor, however, is detection rate. Modulators, which turn a light beam off and on, can switch a billion times a second, but today’s detectors can make only about 100 million measurements a second. Detection rate is what limits existing time-of-flight systems to centimeter-scale resolution.
There is, however, another imaging technique that enables higher resolution, Kadambi says. That technique is interferometry, in which a light beam is split in two, and half of it is kept circulating locally while the other half — the “sample beam” — is fired into a visual scene. The reflected sample beam is recombined with the locally circulated light, and the difference in phase between the two beams — the relative alignment of the troughs and crests of their electromagnetic waves — yields a very precise measure of the distance the sample beam has traveled.
But interferometry requires careful synchronization of the two light beams. “You could never put interferometry on a car because it’s so sensitive to vibrations,” Kadambi says. “We’re using some ideas from interferometry and some of the ideas from LIDAR, and we’re really combining the two here.”
On the beat
They’re also, he explains, using some ideas from acoustics. Anyone who’s performed in a musical ensemble is familiar with the phenomenon of “beating.” If two singers, say, are slightly out of tune — one producing a pitch at 440 hertz and the other at 437 hertz — the interplay of their voices will produce another tone, whose frequency is the difference between those of the notes they’re singing — in this case, 3 hertz.
The same is true with light pulses. If a time-of-flight imaging system is firing light into a scene at the rate of a billion pulses a second, and the returning light is combined with light pulsing 999,999,999 times a second, the result will be a light signal pulsing once a second — a rate easily detectable with a commodity video camera. And that slow “beat” will contain all the phase information necessary to gauge distance.
But rather than try to synchronize two high-frequency light signals — as interferometry systems must — Kadambi and Raskar simply modulate the returning signal, using the same technology that produced it in the first place. That is, they pulse the already pulsed light. The result is the same, but the approach is much more practical for automotive systems.
“The fusion of the optical coherence and electronic coherence is very unique,” Raskar says. “We’re modulating the light at a few gigahertz, so it’s like turning a flashlight on and off millions of times per second. But we’re changing that electronically, not optically. The combination of the two is really where you get the power for this system.”
Through the fog
Gigahertz optical systems are naturally better at compensating for fog than lower-frequency systems. Fog is problematic for time-of-flight systems because it scatters light: It deflects the returning light signals so that they arrive late and at odd angles. Trying to isolate a true signal in all that noise is too computationally challenging to do on the fly.
With low-frequency systems, scattering causes a slight shift in phase, one that simply muddies the signal that reaches the detector. But with high-frequency systems, the phase shift is much larger relative to the frequency of the signal. Scattered light signals arriving over different paths will actually cancel each other out: The troughs of one wave will align with the crests of another. Theoretical analyses performed at the University of Wisconsin and Columbia University suggest that this cancellation will be widespread enough to make identifying a true signal much easier.
“I am excited about medical applications of this technique,” says Rajiv Gupta, director of the Advanced X-ray Imaging Sciences Center at Massachusetts General Hospital and an associate professor at Harvard Medical School. “I was so impressed by the potential of this work to transform medical imaging that we took the rare step of recruiting a graduate student directly to the faculty in our department to continue this work.”
“I think it is a significant milestone in development of time-of-flight techniques because it removes the most stringent requirement in mass deployment of cameras and devices that use time-of-flight principles for light, namely, [the need for] a very fast camera,” he adds. “The beauty of Achuta and Ramesh’s work is that by creating beats between lights of two different frequencies, they are able to use ordinary cameras to record time of flight.”

Cybersecurity Role

Our daily life, economic vitality, and national security depend on a stable, safe, and resilient cyberspace.


Cyberspace and its underlying infrastructure are vulnerable to a wide range of risk stemming from both physical and cyber threats and hazards. Sophisticated cyber actors and nation-states exploit vulnerabilities to steal information and money and are developing capabilities to disrupt, destroy, or threaten the delivery of essential services.


Combating Cyber Crime

 Today’s world is more interconnected than ever before. Yet, for all its advantages, increased connectivity brings increased risk of theft, fraud, and abuse. As Americans become more reliant on modern technology, we also become more vulnerable to cyberattacks such as corporate security breaches, spear phishing, and social media fraud. Complementary cybersecurity and law enforcement capabilities are critical to safeguarding and securing cyberspace. Law enforcement performs an essential role in achieving our nation’s cybersecurity objectives by investigating a wide range of cyber crimes, from theft and fraud to child exploitation, and apprehending and prosecuting those responsible. The Department of Homeland Security (DHS) works with other federal agencies to conduct high-impact criminal investigations to disrupt and defeat cyber criminals, prioritize the recruitment and training of technical experts, develop standardized methods, and broadly share cyber response best practices and tools. Criminal investigators and network security experts with deep understanding of the technologies malicious actors are using and the specific vulnerabilities they are targeting work to effectively respond to and investigate cyber incidents.

How Facebook’s Annual “Hacktober” Campaign Promotes Cybersecurity to Employees

While the word “cybersecurity” may evoke thoughts of highly sophisticated attacks that require fancy computing equipment and skilled hackers, the reality is that most attacks — especially in a corporate environment — involve simpler strategies that depend upon one thing: exploiting human behavior.


Most companies are hard at work building technology to better protect themselves and their users or customers. But technology can only get us so far. People are the most important factor in any company’s cybersecurity strategy, and investing in security engagement goes a long way in helping companies reduce the probability of a breach.


Facebook runs security engagement programs year-round, but the most important tool in our arsenal is Hacktober, an annual, monthlong tradition each October designed to build and maintain a security-conscious culture. It’s our version of National Cyber Security Awareness Month, a campaign to get people involved in cyber security and play their part in making the internet safer and more secure for everyone.


Hacktober has a number of different elements, from phishing tests and marketing campaigns to contests, workshops, and expert talks. Participation is not mandatory, but we find that about one-third of employees participate in at least one activity over the course of the month. Everything is designed to remind our employees how to protect themselves, our company, and the millions of people who use Facebook every day.


Security awareness can be engaging rather than scary — or worse, boring. If we create an interactive and fun environment around security, people will learn important security lessons and retain them throughout the year.


At Facebook, we take a “hacker” approach to security awareness because that ethos is a core part of our culture, which means it resonates with our employees. One of the best examples of this is our Capture the Flag (CTF) competitions.

Bitcoin nears $10,000 mark as hedge funds plough in

Bitcoin has hit a record high after passing $9,000 (£6,700) and is close to reaching five figures as investors in the cryptocurrency shrug off warnings of a bubble.
The cryptocurrency rose to an all-time high of $9,721 on Monday. It is now worth more than seven times an ounce of gold, which is seen as a haven in times of turmoil.
In a remarkable rally, bitcoin started the year at $1,000 and smashed through $5,000 in October.

Analysts said the decision by the Chicago Mercantile Exchange (CME) to launch bitcoin futures in December had fuelled buying, but also warned of the dangers of a speculative bubble building. The digital currency has gained more than 50% since the CME announced its decision on 31 October.
Neil Wilson, senior market analyst at ETX Capital, said: “The legitimacy this gives bitcoin as a tradeable asset is very important. The market cap of bitcoin now exceeds that of IBM, Disney [or] McDonald’s.”
The value of the 16.7m bitcoin units in circulation has exceeded $160bn.

Putting the “AI” in ThAInksgiving

It’s true that AI and machine learning are changing the world, and in a few years, it will be embedded in all of the technology in our lives.
So maybe it makes sense to help folks at home better understand machine learning. After all, without deep knowledge of current tech, autonomous vehicles seem dangerous, Skynet is coming, and the (spoiler warning!) AI-controlled human heat farms of The Matrix are a real possibility.
This stems from a conflation of the very real and exciting concept of machine learning and the very not real concept of “general artificial intelligence,” which is basically as far off today as it was when science fiction writers first explored the idea a hundred years ago.
That said, you may find yourself in a discussion on this topic during the holidays this year, either of your own volition or by accident. And you’ll want to be prepared to argue for AI, against it, or simply inject facts as you moderate the inevitably heated conversation.
But before you dive headlong into argument mode, it’s important that you both know what AI is (which, of course, you do!) and that you know how to explain it.

Understanding Onboard Flash Programming

Firmware often is preprogrammed into flash memory devices prior to the printed-circuit board’s (PCB) manufacture to maintain high throughput and avoid slowing the manufacturing beat rate. Yet there are advantages to programming the flash memory after it has been soldered to the PCB. In-circuit test (ICT), the Joint Test Action Group (JTAG) interface, and external connectors all can be used to program flash devices without impacting manufacturing beat rates. Image size, existing manufacturing infrastructure, system capability, and required programming methods also should be considered in choosing an optimal preprogramming solution.

Onboard Programming Advantages


One of the most significant advantages of onboard programming is that it enables design and manufacturing engineers to combine IC testing and programming into a single manufacturing process, which eliminates the need to perform offboard programming of an IC prior to surface-mounting the device.

Flash memory utilization typically depends on the development stage of a product. In many applications, designers use flash memory to develop, store, and eventually execute firmware and application code. Onboard programming is often used during the development of new application code or firmware. Code is written, compiled, and downloaded onto the flash device on the development board and then tested on the target PCB.
When the hardware and software nears production readiness, it is common practice to preprogram flash memory devices prior to starting high-volume PCB manufacturing flows for two principal reasons. First, firmware loaded onto the device can be used to perform basic booting and testing of the PCB during manufacturing to check system/module functionality. Second, loading the final firmware, operating system (OS), and application code on the flash device prior to manufacturing maintains a high-volume manufacturing beat rate. To support these usage models, multiple vendors provide systems for loading firmware and data into flash memory devices prior to the PCB solder flow process

To support these usage models, multiple vendors provide systems for loading firmware and data into flash memory devices prior to the PCB solder flow process. 
The ability to leverage existing manufacturing systems for testing, coupled with the fast program speeds of flash memory, make onboard programming a viable mainstream solution for programming flash memory. In addition to having no impact on the manufacturing line, other advantages of onboard programming include:  
  •  Faster time-to-market: If a change is made to the flash memory image, the change can be sent directly to the manufacturing line, speeding the delivery time into production. 
  •  Improved quality: Removing the preprogrammed inventory reduces the risk of sending out the wrong version of firmware, OS, or application code as well as the time and resources needed to track units that must be reworked.  
  •  Supply chain simplification: Traditionally, manufacturing operations track both programmed and unprogrammed units, whereas with onboard programming, only unprogrammed flash units need to be monitored.

Onboard Programming Techniques

Several onboard programming (or in-system programming [ISP]) techniques are used to load firmware and data onto a flash device after solder reflow. These techniques include ICT, JTAG, and external connections (Table 1).
ICT is a test methodology that checks PCBs for assembly defects such as shorts, opens, resistance, and capacitance directly after devices are mounted in the solder reflow oven. After undergoing a successful test sequence, flash memory devices can be programmed directly by the ICT equipment. The program time must be very short (approximately 1 to 4 seconds) to avoid negatively impacting the manufacturing beat rate. In addition, programming a memory device with ICT typically requires a low-pin-count interface, which limits the number of nails/pins on the test fixture.
JTAG is an IEEE standard (IEEE 1149.1) that uses boundary scan architecture to test for structural integrity between devices on a PCB. The JTAG interface also can perform ISP of flash memory devices. During the boundary scan check, the interface enables direct control over the memory signals, enabling an image to be programmed into a flash device. JTAG programmers typically write software and data to the flash memory using data bus access similar to the access used to update CPU firmware.
ICT and JTAG are typically used for programming small data images (less
than 16 Mbytes) on flash memory devices like NOR due to the low bandwidth required by these processes (low-pin-count bus or slow clock frequencies). Table 2 compares the theoretical write performance of NOR flash lithography nodes and interfaces. 
External connection and new ICT models are the best techniques for transferring larger data images that require a higher bandwidth. These two techniques provide an opportunity for manufacturing tool and support vendors to enable faster transfers of high-density firmware and data to flash memory devices. ICT testers have recently reached program speeds of 20 Mbytes/s.
External-edge connections accomplish onboard programming using two basic methods. With a microprocessor, data is transferred into the flash device with an existing connector (e.g., USB) using the main microprocessor on the PCB for control. Without a microprocessor, data is transferred into the flash device with an existing connector (e.g., UART) using specific control logic on the PCB dedicated to the manufacturing environment. In this case, the onboard microprocessor is not used.
External connection techniques and new ICT models can transfer data at much higher rates. Table 3 shows the bandwidth that can be achieved using single-level cell (SLC) NAND and e∙MMC memory for a given lithography node. In each case, the device rather than the interface limits the programming bandwidth.

Critical Factors For Onboard ProgrammingWhen choosing an onboard programming method to program images on flash devices, memory type, image size, board design, and existing manufacturing capabilities are all critical factors to consider. 

Firmware code, operating systems, and data files can range from tens of kilobytes to hundreds of megabytes. For a smaller image size (less than 8 Mbytes), ICT and JTAG are ideal because of their low bandwidth. Today, many manufacturing lines use JTAG and ICT to test board-level functionality, so additional tools are not needed. With existing hardware in place and NOR flash products that can program between 1 Mbyte/s and 2 Mbytes/s, onboard programming is an ideal solution when the program time does not exceed 4 seconds and does not impact the manufacturing beat rate. 
The program performance of high-density (32 Mbytes to 1 Tbyte) NAND flash enables the use of optimized onboard programming techniques. SLC NAND is the fastest (5 to 60 Mbytes/s) programming flash memory on the market. However, the flash market is transitioning to managed NAND solutions such as e∙MMC embedded memory that have programming speeds ranging from 10 to 35 Mbytes/s. 
Memory devices with high-bandwidth capabilities use two different techniques for transferring large data images: new ICT models and external connections. Recent ICT models can support fast program speeds for high-density memory devices. External-edge connectors can either use the onboard processor or skip the processor and program the flash memory directly. Both of these external connection techniques require either a PCB design to route the data through the processor or logic onboard to handle bus isolation to program the flash memory.
