6:46 PM | Video game technology. Part 2 of 3: The HD Experience.
  claimtoken-534595084c47dOne of the most recent advances in entertainment technology has been the switch from standard resolution to High Definition. The change has affected not only displays but also the complexity of the media produced. Most TV shows, movies and video games are now made in this format. The capacity to offer higher resolution images even became a powerful weapon in the last version of the console wars. The technology has been so well received by the public that Ultra HD […]

6:42 PM | How To Get Into Hobby RC: Car Basics and Monster Truckin'
After a few months of lightly tapping, it’s finally time to pound the drum about RC cars. Of course, there are countless styles of cars that you can get into. For now, I will focus on the type of cars that I recommended for beginners in the first article of this series: 2-wheel-drive, electric-powered, monster trucks.Just like every other facet of RC, cars have benefited from recent advancements in radio, motor and battery technology. As I looked over my aging collection of well-used […]

5:38 PM | In Brief: Diagnosing iOS Battery Drain
Scotty Loveless, an ex-Genius Bar employee, recently posted this comprehensive guide to diagnosing and solving iOS battery issues, based on his two years working for Apple and hundreds of Genius Bar appointments with users complaining about their iPhone's battery. There's a lot of practical advice here, such as how to test your iOS battery drain rate by noting down usage and standby times, but Loveless also offers some very specific tips that he claims make a big difference. Disabling Location […]

5:00 PM | The Low-Budget Movie Gimmicks of Cinema Past
With so many people watching movies at home with Blu-ray or through streaming services, Hollywood has been desperate to bring people back to theaters. This is why we’ve had the big 3D revival. With the success of films like Gravity, IMAX has also been a hot ticket. And overseas, 4D cinema has been very successful as well.4D is a cinema technology that can encompass many different experiences, and one that used to be most associated with the gimmick of Smell-O-Vision. In Asia, there are […]

8:54 PM | Tested Explains: What Does it Mean to Call on a "Secure Line"?
If decades of televised White House dramas and Hollywood espionage thrillers have taught us anything, it's that barking "Get me a secure line!" into your phone is about all it takes to establish a private, encrypted call.Alas, security is rarely so simple – and for decades, encrypting phone conversations actually took a great deal of work. Only in recent years has encryption become more accessible, and it's still a lot more effort than pop culture would have you believe.The secure line's […]

8:33 PM | Testing: Adobe Lightroom Mobile for iPad
You could hear my cheers resonate throughout my house last night when I read that Adobe had finally released a mobile version of its Lightroom photo processing application for iOS. This wasn't an unexpected move--there were leaked mentions and details of this program back in January--but it's still exciting to finally see and use it in person. Lightroom mobile is currently an iPad-only app (iPhone version coming soon, but no word on Android) that's available to download right now from the app […]

6:11 PM | The Best Wi-Fi Router (So Far)
If you need to pick up a new router today, you should get the Asus RT-AC56U. It’s not the absolute fastest router on the market, so why do we like it? It turns out that most Wi-Fi tests are performed using technology that even the absolute latest laptops won't see for years, and the speeds touted on the box and in many reviews don't actually reflect real-world speeds. Most of us don’t own devices that would take advantage of that extra technology—even if you own the latest […]

5:00 PM | In Brief: Gender Responses to Virtual Reality Simulations
While the internet has a laugh over the White Guys Wearing Oculus Rifts Tumblr, there's some genuine discussion about the potential differences in the way that biological factors may affect a person's experience of virtual reality. To put it bluntly, there's the possibility that women may not be as responsive to current virtual reality tech as men. Danah Boyd, a researcher at Microsoft Research and Assistant Professor at New York University, recently shared the results of a 2000 study she […]

7:09 AM | Living with Photography: Testing the Fujifilm X100s Digital Camera
It's been a while since I've done one of these columns, and that's not because I haven't been taking photos or thinking about photography. On the contrary, I've taken about twice as many photos in the past month than on an average month (just past 22K photos in Lightroom!), both from going to week-long events like SXSW and from testing a bunch of new camera gear. Some of that gear includes new smartphones, like the HTC One M8 that I've been testing, but also new cameras and lenses that I've […]

5:00 AM | IRNN: Generalized Nonconvex Nonsmooth Low-Rank Minimization - implementation -
 Generalized Nonconvex Nonsmooth Low-Rank Minimization by Canyi Lu, Zhouchen Lin, Shuicheng Yan.As surrogate functions of L0-norm, many nonconvex penalty functions have been proposed to enhance the sparse vector recovery. It is easy to extend these nonconvex penalty functions on singular values of a matrix to enhance low-rank matrix recovery. However, different from convex optimization, solving the nonconvex low-rank minimization problem is much more challenging than the nonconvex […]

10:17 PM | An Uncertain Climate Future for Chicago
An Uncertain Climate Future for Chicago07Apr2014It’s a short question, but a massive one: How will climate change impact Chicago? Scientific studies and climate models tell us that climate change is happening, and make broad forecasts about how different the Earth’s climate will be over the next century. But when it comes to making specific predictions about how climate change will affect the lives of people in a particular city, today’s models don’t provide any clear […]

9:55 PM | Testing: DJI Phantom 2 Vision+ Quadcopter Drone
For the past week and a half, I've been testing DJI's new Phantom 2 Vision+ quadcopter. The RC quad, which was officially announced yesterday at the annual NAB (National Association of Broadcasters) convention in Las Vegas, is the first real prosumer quadcopter I've flown. And in my testing time with it, I've become completely addicted to flying it. Days and nights are now framed in my mind in terms of when I can find time to take it out to fly, and how many battery recharge cycles I can fit […]

5:30 PM | The Zoidberg Project, Part 10: Mold Finishing and Foam Latex
The primary mold for the Zoidberg sculpture is complete, but there are still a few things to do to make this mold functional for casting masks. The first thing I need to do is to drill the bolt holes and add T-nuts to the flange of the mold (the flat parts around the outside that connect the two halves together). Because of the rigidity of the flange, I don't need to put a gajillion bolts in it to keep the mold stable. I start by drilling in a few typical places: near the bottom at the end of […]

4:00 PM | In Brief: Google Reportedly Developing Android TV Set-Top UI
Over the weekend, The Verge posted screenshots and details from a document they claim to show Google's next foray into the living room set-top device business, an interface called "Android TV." The screenshots of the purported platform show a tile-based interface very similar to what you'd find on the Roku, Apple TV, or even Xbox One: large and colorful shortcuts to apps and videos. According to The Verge, Google's vision for Android TV are far-removed from the ambitions laid out in their […]
