Low-Power Deep Learning — it’s a media release for proprietary tech, but interesting that people are working on low-power deep learning neural nets. As Pete Warden noted, this kind of research will be at the center of smart sensors. (via Pete Warden)
Tesla’s Self-Improving Autopilot — it learns when you “rescue” (aka take control back from autopilot), so it’s getting better day by day. Musk said that Model S owners could add ~1 million miles of new data every day, which is helping the company create “high-precision maps.” Navteq, Google Maps, Waze … new map data is still valuable.
The Digital Revolution in Higher Education Has Already Happened (Clay Shirky) — and no-one noticed. I read half of this before going “holy crap this is good, who wrote it?” I’m a Shirky junkie (I bet his laundry lists cite Habermas and the Peace of Westphalia). At the current rate of growth, half the country’s undergraduates will have at least one online class on their transcripts by the end of the decade. This is the new normal. But, As long as we discuss online education as a pedagogic revolution rather than an organizational one, we aren’t even having the right kind of conversation. The dramatic adoption of online education is not mainly a change in the content of classes. It’s a change in the institutional form of college, a demand for more flexibility by students who have to manage the increasingly complicated triangle of work, family, and school.
System Automatically Converts 2-D to 3-D (MIT) — hilarious strategy! They constrained their domain: broadcast soccer games. The MIT and QCRI researchers essentially ran this process in reverse. They set the very realistic Microsoft soccer game “FIFA13” to play over and over again, and used Microsoft’s video-game analysis tool PIX to continuously store screen shots of the action. For each screen shot, they also extracted the corresponding 3-D map. […] For every frame of 2-D video of an actual soccer game, the system looks for the 10 or so screen shots in the database that best correspond to it. Then it decomposes all those images, looking for the best matches between smaller regions of the video feed and smaller regions of the screen shots. Once it’s found those matches, it superimposes the depth information from the screen shots on the corresponding sections of the video feed. Finally, it stitches the pieces back together. Brute-forcing soccer. Ok, perhaps “hilarious” for a certain type of person. I am that person.
This World of Ours (PDF) — funny and accurate skewering of the modern security researcher. In the real world, threat models are much simpler (see Figure 1). Basically, you’re either dealing with Mossad or not-Mossad. If your adversary is not-Mossad, then you’ll probably be fine if you pick a good password and don’t respond to emails from ChEaPestPAiNPi11s@virus-basket.biz.ru. If your adversary is the Mossad, YOU’RE GONNA DIE AND THERE’S NOTHING THAT YOU CAN DO ABOUT IT. The Mossad is not intimidated by the fact that you employ https://.
Ligra — a lightweight graph processing framework for shared memory. It is particularly suited for implementing parallel graph traversal algorithms where only a subset of the vertices are processed in an iteration.
Observational Signatures of Self-Destructive Civilisations (arXiv) — Using the Earth as an example, we consider a variety of scenarios in which humans could extinguish their own technological civilisation. Each scenario presents some form of observable signature that could be probed by astronomical campaigns to detect and characterise extrasolar planetary systems. I feel like there’s a business form of this paper, too …
Theft, Lies, and Facebook Video (Medium) — inexcusable that Facebook, a company with a market cap of $260 BILLION, launched their video platform with no system to protect independent rights holders. It wouldn’t be surprising if Facebook was working on a solution now, which they can roll out conveniently after having made their initial claims at being the biggest, most important thing in video. In the words of Gillian Welch, “I wanna do right, but not right now.“
The Web We Have to Save — Nearly every social network now treats a link just the same as it treats any other object — the same as a photo, or a piece of text — instead of seeing it as a way to make that text richer. You’re encouraged to post one single hyperlink and expose it to a quasi-democratic process of liking and plussing and hearting: Adding several links to a piece of text is usually not allowed. Hyperlinks are objectivized, isolated, stripped of their powers.
California Regulator Pushing for All Cars to be Electric (Bloomberg) — Nichols really does intend to force automakers to eventually sell nothing but electrics. In an interview in June at her agency’s heavy-duty-truck laboratory in downtown Los Angeles, it becomes clear that Nichols, at age 70, is pushing regulations today that could by midcentury all but banish the internal combustion engine from California’s famous highways. “If we’re going to get our transportation system off petroleum,” she says, “we’ve got to get people used to a zero-emissions world, not just a little-bit-better version of the world they have now.” How long until the same article is written, but about driverless cars?
LLVM for Grad Students — fast intro to why LLVM is interesting. LLVM is a great compiler, but who cares if you don’t do compilers research? A compiler infrastructure is useful whenever you need to do stuff with programs.
Speed as a Habit — You don’t have to be militant about it, just consistently respond that today is better than tomorrow, that right now is better than six hours from now. This is chock full of good advice, and the occasional good story.
Punctuated Equilibrium in the Large-Scale Evolution of Programming Languages (PDF) — Here we study the large-scale historical development of programming languages, which have deeply marked social and technological advances in the last half century. We analyse their historical connections using network theory and reconstructed phylogenetic networks. Using both data analysis and network modeling, it is shown that their evolution is highly uneven, marked by innovation events where new languages are created out of improved combinations of different structural components belonging to previous languages. These radiation events occur in a bursty pattern and are tied to novel technological and social niches. The method can be extrapolated to other systems and consistently captures the major classes of languages and the widespread horizontal design exchanges, revealing a punctuated evolutionary path.

Toyota’s Spaghetti Code — Toyota had more than 10,000 global variables. And he was critical of Toyota watchdog supervisor — software to detect the death of a task — design. He testified that Toyota’s watchdog supervisor ‘is incapable of ever detecting the death of a major task. That’s its whole job. It doesn’t do it. It’s not designed to do it.’ (via @qrush)
Google’s Design Icons (Kevin Marks) — Google’s design icons distinguish eight kinds of airline seats but has none for trains or buses.
US Driverless Car Accidents (NYTimes) — Delphi sent AP an accident report showing its car was hit, but Google has not made public any records, so both enthusiasts and critics of the emerging technology have only the company’s word on what happened. The California Department of Motor Vehicles said it could not release details from accident reports. This lack of transparency troubles critics who want the public to be able to monitor the rollout of a technology that its own developers acknowledge remains imperfect.
Architecting Websites for the HTTP/2 Era — HTTP/2 introduces multiplexing, which allows one TCP/IP connection to request and receive multiple resources, intertwined. Requests won’t be blocking anymore, so there is no need for multiple TCP connections on multiple domain names. In fact, opening multiple connections would hurt performance in HTTP/2. This is going to be exciting.
tripmode — software to control the downloads your Mac software wants to make, even when you’re tethered or on a pay-per-meg hotspot.
The Difference Between Direct Competition and Disruption — As the ships grow, their engines have become vastly more efficient and sophisticated, the fuel mix has changed, and complex IT infrastructure has been put in place to coordinate the movement of the containers and ships. But fundamentally, the underlying cost structure of the business has not changed from 1950, when the first container ships carried a mere 500 to 800 containers across the world. (via Salim Virani)
The Impact of Copyright Policy Changes on Venture Capital Investment in Cloud Computing Companies (PDF) — Our findings suggest that decisions around the scope of copyrights can have significant impacts on investment and innovation. We find that VC investment in cloud computing firms increased significantly in the U.S. relative to the EU after the Cablevision decision. Our results suggest that the Cablevision decision led to additional incremental investment in U.S. cloud computing firms that ranged from $728 million to approximately $1.3 billion over the two-and-a-half years after the decision. When paired with the findings of the enhanced effects of VC investment relative to corporate investment, this may be the equivalent of $2 to $5 billion in traditional R&D investment.
Max Headroom Oral History — “Anybody under the age of 25 just loved it. And anybody above that age was just completely confused.”
Auto Makers Say You Don’t Own Your Car (EFF) — Most of the automakers operating in the U.S. filed opposition comments through trade associations, along with a couple of other vehicle manufacturers. They warn that owners with the freedom to inspect and modify code will be capable of violating a wide range of laws and harming themselves and others. They say you shouldn’t be allowed to repair your own car because you might not do it right. They say you shouldn’t be allowed to modify the code in your car because you might defraud a used car purchaser by changing the mileage. They say no one should be allowed to even look at the code without the manufacturer’s permission because letting the public learn how cars work could help malicious hackers, “third-party software developers” (the horror!), and competitors.
Remotely Bricking Cars (BoingBoing) — story from 2010 where an intruder illegally accessed Texas Auto Center’s Web-based remote vehicle immobilization system and one by one began turning off their customers’ cars throughout the city.
Machine Learning Classification over Encrypted Data (PDF) — It is worth mentioning that our work on privacy-preserving classification is complementary to work on differential privacy in the machine learning community. Our work aims to hide each user’s input data to the classification phase, whereas differential privacy seeks to construct classifiers/models from sensitive user training data that leak a bounded amount of information about each individual in the training data set. See also The Morning Paper’s unpacking of it.
Privacy of Phone Audio (Reddit) — unconfirmed report from Redditor I started a new job today with Walk N’Talk Technologies. I get to listen to sound bites and rate how the text matches up with what is said in an audio clip and give feed back on what should be improved. At first, I though these sound bites were completely random. Then I began to notice a pattern. Soon, I realized that I was hearing peoples commands given to their mobile devices. Guys, I’m telling you, if you’ve said it to your phone, it’s been recorded…and there’s a damn good chance a 3rd party is going to hear it.
Solar Hits Parity in 10 States, 47 by 2016 (Bloomberg) — The reason solar-power generation will increasingly dominate: it’s a technology, not a fuel. As such, efficiency increases and prices fall as time goes on. The price of Earth’s limited fossil fuels tends to go the other direction.
Facebook’s Top Open Data Problems (Facebook Research) — even if you’re not interested in Facebook’s Very First World Problems, this is full of factoids like Facebook’s social graph store TAO, for example, provides access to tens of petabytes of data, but answers most queries by checking a single page in a single machine.
