5:00 AM | Stable, Robust and Super Fast Reconstruction of Tensors Using Multi-Way Projections - implementation -
Stable, Robust and Super Fast Reconstruction of Tensors Using Multi-Way Projections by Cesar F. Caiafa, Andrzej CichockiWe introduce an analytical reconstruction formula that allows one to recover an Nth-order data tensor from a reduced set of multi-way compressive measurements by exploiting its low multilinear-rank structure. Moreover, it is shown that, an interesting property of multi-way measurements allows us to build the reconstruction based on compressive linear measurements of […]

10:48 PM | Awesome Jobs: Meet Martin Nweeia, Narwhal Expert (and Dentist!)
Martin Nweeia knows more about narwhals than almost anyone in the world. More specifically, he’s probably the world’s foremost expert on narwhal tusks. But Nweeia is only sort-of a marine mammal biologist. He’s actually a practicing dentist and a clinical instructor at the Harvard School of Dental Medicine. This guy knows from teeth. So, while it might seem weird that he studies narwhals, if you think about it, there’s some sense to his in-depth knowledge of these […]

9:25 PM | Remembering Ann Yasuhara
Ann will be missed Ann Yasuhara was a mathematician and a complexity theorist, who passed away this June 11th. She lived over half of her 82 years in Princeton, and was a member of the faculty of computer science at Rutgers since 1972. Today Ken and I send our thoughts and condolences to Ann’s husband […]

9:07 PM | In Brief: Finding Innovation in Vinyl Record Technology
We've previously written about Third Man Records and the process of creating vibrant vinyl records, but Jack White's record label is doing more than mixing colors into the vinyl press. This Smithsonian story explores different technologies and tricks being used by small labels and makers to mix up the venerable analog record. Some are experiments in materials, like the laser cut maple wood record by Amanda Ghassaei, but others, like adding hidden tracks in grooves beneath label at the center of […]

8:40 PM | 7 Things Learned from Google's Cardboard VR Experiment
After our initial hands-on with Google's Cardboard virtual reality kit, I spent a bunch more time last night going through the demo app and the Chrome experiments. There were a few demos we didn't get to try on camera, like the Windy Day interactive short film that was previously only available for the Moto X. And while it's obvious that Cardboard is not a direct competitor to the Oculus Rift, the VR experience it could provide is genuinely impressive, and even immersive. It's not the first VR […]

5:16 PM | In Brief: South Park Recreated for Oculus Rift from Scratch
Members of a small production company, Tool, spent a few short weeks last month building the world of South Park in the Unity game engine to be experienced with the Oculus Rift development kit. South Park is faithfully recreated based on the layout presented in the Stick of Truth game, as well as what geography and easter eggs could be extrapolated from the show's intro sequence. The exercise, meant to hone Tool's team in Unity and Oculus development, was finished in time for the Cannes Lions […]

4:35 PM | The Best Wi-Fi Router (for Most People)
If you have a laptop or smartphone that uses wireless-ac technology and you're ready to upgrade your router, you should get the Netgear R6250. The R6250 has the best combination of speed, price, stability, and features of any router in its price range. It can make your new device's Wi-Fi connection up to three times faster than a wireless-n router could. It's a smidge more expensive than the sweet spot for a router of its class (hovering around $130-$145 on Amazon), but we feel the benefits are […]

12:19 PM | Simultaneous Measurement of Complementary Observables with Compressive Sensing
Dick Gordon and several other readers mentioned the following paper to me. It aims at doing something that was thought to be impossible: i.e. measuring both position and momentum of a system at the same time. From afar, the Heisenberg principle says it cannot be done but as the authors mention:...We strongly emphasize that our technique does not violate the uncertainty principle; at no point does a single detection event give precise information about both position and momentum. Instead, each […]

11:24 AM | Classical programming
The classical education model is based on the trivium of grammar, logic, and rhetoric. See, for example, Dorothy Sayers’ essay The Lost Tools of Learning. The grammar stage of the trivium could be literal language grammar, but it also applies more generally to absorbing the basics of any subject and often involves rote learning. The […]

4:00 PM | Everything You Need to Know about Android L
Android has had the same basic aesthetic since Ice Cream Sandwich debuted two and a half years ago. Sure, the colors and layouts have changed a bit, but Holo has been alive and well all this time. KitKat showed the first break from that design when it was announced last year, but Android L is going to be the start of a new era for Android.This is the biggest update to the platform since at least 2.0, but the more I see of Android L, the more I think this could be the biggest thing to ever […]

3:09 PM | In Brief: Sugru Builds a Multi-Chamber Water Cannon
It's totally a marketing project, but the team at Sugru have machined a pretty sweet multi-chamber water pistol. Its use of the actual Sugru product is clever--this Instructables guide shows how the team utilized the putty to connect and seal PVC pipes for the pistons and insulate the electronic switches. Maybe a little superfluous when building an overly complex water gun, but a cool project nonetheless. I've used Sugru in the past for more practical applications, like repairing frayed laptop […]

8:15 AM | Facebook was probably ethically wrong, but morally OK in studying user emotions
Facebook did a study of how its users react to different sorts of stories in their feeds, namely by looking at emotional words in posts and giving different users different mixes of posts. Turns out that there is a tiny but measurable effect … Continue reading →
