4:14 PM | 24 Hours with the Acer Iconia A1 830
We’ve recently got our hands on the latest tablet from Acer.  It’s been released quietly and without the usual fanfare of PR promotion but don’t let that fool you into thinking that this is an insignificant device.  What is this device that we speak of… well it’s an 8″ tablet that looks VERY similar to […]

10:05 AM | Is There Anything Beyond Quantum Computing?
So I’ve written an article about the above question for PBS’s website—a sort of tl;dr version of my 2005 survey paper NP-Complete Problems and Physical Reality, but updated with new material about the simulation of quantum field theories and about AdS/CFT.  Go over there, read the article (it’s free), then come back here to talk about it if […]

9:55 AM | Sparse PCA: Covariance Thresholding and an AMP based approach
No implementation yet, but new ways of going about the Sparse PCA problem. I will be adding the following figure to the phase transition figure in the Advanced Matrix Factorization Jungle page for the Sparse PCA paragraph. As I mentioned in slide 13 of this recent ML Meetup presentation, to the untrained eye, sparse PCA is a solved problem, but the back story is a little bit more complex as related in the first paper: ....Over the last ten years, a significant effort […]

7:17 AM | Behind the Scenes at Kernerworks' Workshop
What do special effects veterans do when Hollywood relies increasingly less on practical effects and more on computer generated imagery? The effects experts at Kernerworks (who have worked with Jamie and Adam in the past) turned their fabrication experience into developing and building realistic trauma mannequins the military to train field medics. These robots not only behave realistically to simulate injuries, they look incredibly lifelike as well--some even have the capability to spurt […]

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.

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.

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 […]

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 […]
