5:39 PM | IPv6 seen in the wild!
Don't ask how I got here, but I was looking at the revision history of a Wikipedia page and saw: (cur | prev) 16:20, 18 December 2014‎ 2607:f470:8:b044:3d66:5782:2dba:2c8b (talk)‎ . .

5:31 PM | What You Should Know about Getting an FCC License for Flying FPV
As much as we love to give you an inside look at all sorts of cool toys and gadgets, the job also includes a responsibility to educate you on the finer points of using those toys responsibly and lawfully. Such is the case with our recent videos featuring Carlos Puertolas (Charpu). Those videos have captured the attention of many readers who are now interested in First Person View (FPV) quad-rotor racing--including me. What you might not know is that one of the prerequisites for most types of […]

5:00 PM | Testing: Google Nexus 6 Smartphone
For most of 2014 it looked like we weren't going to see a new Nexus phone at all, but the rumors turned out to be wrong and Google announced the Nexus 6 alongside the Nexus 9. The Nexus 6 is the most expensive Nexus flagship phone ever made, and it's also by far the largest. It marks Motorola's first attempt at a Nexus as well.With so many changes to the Nexus strategy, you're probably wondering how it all turned out. Well, let's dig in.Yes, It's a Very Large PhoneThe Nexus 6 packs a 5.96-inch […]

1:00 PM | Striving for simplicity, arriving at complexity
This post is a riff on a line from Mathematics without Apologies, the book I quoted yesterday. In an all too familiar trade-off, the result of striving for ultimate simplicity is intolerable complexity; to eliminate too-long proofs we find ourselves “hopelessly lost” among the too-long definitions. [emphasis added] It’s as if there’s some sort of […]

11:11 PM | Problem solvers and theory builders
From Mathematics without Apologies: It’s conventional to classify mathematicians as “problem solvers” or “theory builders,” depending on temperament. My experiences and the sources I consulted in writing this book convince me that curiosity about problems guides the growth of theories, rather than the other way around. Alexander Grothendieck and Robert Langlands … count among the […]

11:00 PM | Awesome Jobs: Meet Chris Buddle, Arachnologist
Chris Buddle spends a lot of his time crawling around on his hands and knees in the high arctic. He’s one of the world’s very few experts on the eight-legged creepy crawlies that send a shiver up the spine of most folks. Buddle is an arachnologist and an associate professor of forest insect ecology at McGill University. And he loves spiders. He chatted with us about how the heck he goes about finding teeny tiny animals scuttling around the northern Tundra and why spiders […]

8:30 PM | Living with Photography: My Favorite Photos Taken in 2014
Oh shoot. I looked at the calendar and realize it's already the middle of January. We're back from CES, and as I was reviewing photos from the show, I remembered that I had ran out of time during the holidays to post my annual gallery of my favorite photos taken that year. In the past two years, I've called this series my Favorite Tested Photos, but I'm changing that this year to just my favorite photos in general, taken either for work or outside of it. Out of 11039 photos taken in 2014, these […]

7:00 PM | The Best On-Ear Headphones At Any Price
This post was done in partnership with The Wirecutter, a list of the best technology to buy.Read the full article below atTheWirecutter.comThe $180 Bose SoundTrue offer the best combination of sound quality, portability, and comfort, of any on-ear headphone. If you don’t like in-ear headphones, or need something more portable than bulky over-ear headphones, the SoundTrue are the ones to get.Why should you trust me?We came to this conclusion after dozens of hours of research and, with […]

6:00 PM | In Brief: Charles Young's Tiny Papercraft City
Put the word miniature and papercraft together and you're going to perk my ears. Artist Charles Young has been working on a really neat ongoing miniature papercraft project called Paperholm, in which he builds a new house, tower, castle, farm, or other city structure every day using white cardstock. His buildings--many of which he animates for short looping videos--are apparently inspired by the photographs of industrial structures by Bernd and Hilla Becher. Young's papercraft creations also […]

4:07 PM | Random Matrices for the People: An Introduction to Matrix Concentration Inequalities
Compressive Sensing, Random Features, it's all in there: An Introduction to Matrix Concentration Inequalities by Joel Tropp In recent years, random matrices have come to play a major role in computational mathematics, but most of the classical areas of random matrix theory remain the province of experts. Over the last decade, with the advent of matrix concentration inequalities, research has advanced to the point where we can conquer many (formerly) challenging problems with a page or two of […]

10:58 AM | In the era of #repligate: What are valid cues for the trustworthiness of a study?
In a recent lecture I talked about the replication crisis in psychology. After the lecture my students asked: “We learn so much stuff in our lectures, and now you tell us that a considerable proportion of these ‘facts’ probably are just false positives? Then, what can we believe at all?”. A short discussion soon led […]

1:16 AM | Salvius gives a thumbs up to students at Tech Foundry
Students from the Tech Foundry worked to build a pair of robotic hands for Salvius at this weekends workshop. While working, students learned that the length of each digit in a finger follows the pattern of a Fibonacci sequence. The Fibonacci sequence occurs quite commonly in nature, however the significance of this pattern in the human hand is that it allow the fingers to curl into a fist shape which is why human hands are good at using a wide variety of tools. In addition, it was shown […]

12:00 AM | 8 Interesting Things We Missed at CES 2015
We saw a lot of cool stuff at this year's CES, and our videos from the floor are still being edited to roll out on the site over the next week and a half. In addition to our featured Oculus VR demo and interview, we raced quadcopters, checked out Razer's OSVR dev kit, and even listened to Sony's new $1100 Walkman. But we couldn't cover everything being shown at the Las Vegas Convention Center, and there were definitely interesting pieces of technology that we let slip through the cracks. […]

7:43 PM | New development in cancer research scandal
My interest in the Anil Potti scandal started when my former colleagues could not reproduce the analysis in one of Potti’s papers. (Actually, they did reproduce the analysis, at great effort, in the sense of forensically determining the erroneous steps that were carried out.) Two years ago, the story was on 60 Minutes. The straw […]

7:00 PM | FOCS Workshop on higher-order Fourier analysis: A Review
This is a guest post by my student Amirali Abdullah. Amirali attended FOCS 2014 and has a number of interesting reflections on the conference.2014 was my first experience of attending a FOCS conference, and finally seeing the faces* (attached to some of the cutting edge as well as classical results in theoretical computer science. Not only did I get to enjoy the gentle strolls between conference halls, and hearing about fields I'd never known existed, I had the pleasure of doing so while […]

5:11 PM | Quantum computing news items (by reader request)
Within the last month, there was a major milestone in the quest to build a scalable quantum computer, and also a major milestone in the quest to figure out what you would do with a quantum computer if you had one.  As I’ve admitted many times, neither of those two quests is really the reason […]

4:00 PM | Privacy is dead, but not because Scott McNealy said so.
I decided to experiment with using Medium for a long-form not-quite technical post on the evolution of research in data privacy.The idea of privacy has driven much of our concerns over data for the last few years, and has been the driver of extremely successful research efforts, most notably in differential privacy.What we’re seeing now though is a pivot away from the undifferentiated and problematic notion of privacy in data towards a more subtle and nuanced notion of how data is […]
