11:18 PM | In Brief: Hands-Free Systems In Cars Are Still a Major Distraction
The AAA and University of Utah released a pair of studies this week that attempted to quantify the the mental workload required to use voice-activated, in-car entertainment systems. For the first time, they used the actual systems found in cars, as well as Apple's Siri.Their results indicate that the voice-activated systems require enough mental processing on the part of the driver that they present a significant degradation to a driver's performance, even if he's able to keep his eyes on the […]

6:40 PM | Screenprints of Adam's Drawings at Tested: The Show!
If you're in the San Francisco area and haven't bought a ticket to our upcoming stage show, here's one more reason you'll want to be there. Tested: The Show will be the first place we'll be selling an exclusive screenprint set of Adam's Mecha-Hand drawings. In the process of researching and building his awesome Mecha-Hand prop replica, Adam detailed all the components--to scale--in a series of schematic drawings. We've turned two of them into a set of screenprints--12"x16", printed on heavy […]

3:49 PM | Fuel-Free Flight: The State of Electric Airplanes
When the all-electric E-Fan made its first flight earlier this year, it signaled a breakthrough in the progress of electric aircraft. Although its performance compares well to other contemporary electric designs, the E-Fan does not represent any major technological leaps. More significant is the company behind the E-Fan: Airbus, the European firm better known for producing large airliners. Airbus is a large, multinational company that is deeply entrenched in the business of burning fossil […]

2:45 PM | In Brief: MIT Exploring "Second Skin" Spacesuit Design
Last month, MIT researchers at the school's aeronautics and astronautics department revealed that they have been working on materials to design a skintight pressure suit for astronauts. The idea of this "second skin" suit would be to use shape-memory alloys that can spring into a programmed shape with heat to make pressure suits form-fitting and mobile. The SMA material they're working with is nickel-titanium, which can be spun into coils and expand and tighten-up with sufficient trigger heat. […]

8:03 AM | Algorithms is the new Algorithms...
Hal Daumé wrote a rather provocative post titled ‘Machine Learning is the new algorithms’, and has begged someone to throw his gauntlet back at him. Consider it now thrown !His thesis is the following quote:Everything that algorithms was to computer science 15 years ago, machine learning is todayAnd among the conclusions he draws is the following:we should yank algorithms out as an UG requirement and replace it with machine learningHaving spent many years having coffees and […]

5:00 AM | Generalized Low Rank Models - implementations in Julia and Spark -
Here is a large installment of Advanced Matrix Factorization instances. The codes are also available in Julia and Spark (a sign of things to come ?)Generalized Low Rank Models by Madeleine Udell, Corinne Horn, Reza Zadeh, Stephen Boyd Principal components analysis (PCA) is a well-known technique for approximating a data set represented by a matrix by a low rank matrix. Here, we extend the idea of PCA to handle arbitrary data sets consisting of numerical, Boolean, categorical, ordinal, and other […]

5:00 AM | Coreset and PCA: Distributed k-Means and k-Median Clustering on General Topologies - implementation -
Distributed k-Means and k-Median Clustering on General Topologies by Maria Florina Balcan, Steven Ehrlich, Yingyu LiangThis paper provides new algorithms for distributed clustering for two popular center-based objectives, k-median and k-means. These algorithms have provable guarantees and improve communication complexity over existing approaches. Following a classic approach in clustering by [13], we reduce the problem of finding a clustering with low cost to the problem of finding a coreset of […]

12:46 PM | John Napier
Julian Havil has written a new book John Napier: Life, Logarithms, and Legacy. I haven’t read more than the introduction yet — a review copy arrived just yesterday — but I imagine it’s good judging by who wrote it. Havil’s book Gamma is my favorite popular math book. (Maybe I should say “semi-popular.” Havil’s books […]

3:26 AM | Living with Photography: The Nonprofessional
Surprise, time for a long overdue Living with Photography column--I missed writing this regularly. I'm returning this week to talk about something that's been on my mind for a while now--a question I've been struggling to wrap my thoughts around since the summer: what defines a professional photographer? Or more specifically: what's the line that separates an amateur and a professional photographer?This question started bothering me at this year's Comic-Con, where I met a bunch of Tested […]

10:44 PM | Andreessen-Horowitz Again
Andreessen Horowitz had a second Academic Roundtable, gathering together academics, VCs, and people in startups to talk for a few days about a variety of topics.  I wasn't sure why I was invited the first time (which I wrote about last year), and am even less clear on why I was invited back, but I again had a very good time.  Before a few words about the talks, the high order point:  I'm told that most/all of the talks will be put online over the coming weeks.  So if you're […]
