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 […]

7:25 AM | Ultimate Prop Wishlists - 4/8/2014
This week, Adam, Will, and Norm discuss their prop wishlists, the things they're always on the lookout for in a variety of categories. Also discussed: the new Cosmos, the old Cosmos, and The Truman Show. Apologies for the lost video in the final minutes of the podcast. Our GoPro failed midway through the recording.

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 […]

8:18 AM | Directed isoperimetry and Bregman divergences.
A new cell probe lower bound for Bregman near neighbor search via directed hypercontractivity. Amirali Abdullah and I have been pondering Bregman divergences for a while now. You can read all about them in my previous post on the topic. While they generalize Euclidean geometry in some nice ways, they are also quite nasty. The most important nastiness that they exhibit is asymmetry:\[ D_\phi(x, y) \ne D_\phi(y, x)\]What's worse is that this asymmetry can grow without bound. In particular, […]

5:00 AM | Scalable Robust Matrix Recovery: Frank-Wolfe Meets Proximal Methods
We mentioned Frank-Wolfe recently: Scalable Robust Matrix Recovery: Frank-Wolfe Meets Proximal Methods by Cun Mu, Yuqian Zhang, John Wright, Donald GoldfarbRecovering matrices from compressive and grossly corrupted observations is a fundamental problem in robust statistics, with rich applications in computer vision and machine learning. In theory, under certain conditions, this problem can be solved in polynomial time via a natural convex relaxation, known as Compressive […]

11:37 PM | FTL: Advanced Edition Adds More Space and an iPad Version
One of my favorite games of 2012 was FTL. It's a space sim roguelike-like unlike anything The game is deceptively simple and endlessly entertaining. In it, you control the crew of a starship on a desperate mission to stop the rebel alliance, or something like that. The upshot is that you control the crew, assigning them tasks like ship repair, arming the weapons, or cranking up the engines while traversing system after system. Because the game has roguelike elements, each time you play, the map […]

1:15 PM | Deep ConvNets; "Astounding" baseline for vision
Last night, Pierre Sermanet gave a talk on OverFeat and ConvNets. The meetup was triggered by one of the Pierre's post on Google+ where he mentioned an ArXiv preprint where some folks at KTH [2] used features from OverFeat [1,3] and an SVM to get results they called "astounding" and said so in the title of the paper ( CNN Features off-the-shelf: an Astounding Baseline for Recognition ). The use of such wording is rare (If you recall similar words such as "stunning" or "quite […]
