Efficient Algorithms for Public-Private Social Networks — Google Research paper on privacy-respecting algorithms for social networks. From the overview: the models of privacy we’re landing on (nodes or edges in the graph are marked as “private” by a user) mean that enforcing these privacy guarantees translates to solving a different algorithmic problem for each user in the network, and for this reason, developing algorithms that process these social graphs and respect these privacy guarantees can become computationally expensive. The paper shows how to efficiently approximate some of the graph operations required to run a social network.
Rise of Networked Platforms for Physical World Services (Tim O’Reilly) — the central player begins by feeding its network of suppliers, but eventually begins to compete with it. […] Over time, as networks reach monopoly or near-monopoly status, they must wrestle with the issue of how to create more value than they capture — how much value to take out of the ecosystem, versus how much they must leave for other players in order for the marketplace to continue to thrive.
Book Recommendations from BLDBLOG — Winslow memorably pointed out how farmers in the Sinaloa region of Mexico had been swept up into the cartel’s infinitely flexible method of production, and that, despite any ensuing role growing and harvesting marijuana or even poppies, the cartel offered them new jobs in logistics, not agriculture. “They didn’t want to be farmers,” Winslow said at Bookcourt, “they wanted to be FedEx.”
The End of the Internet Dream (Jennifer Granick) — this is all gold. Something resonating with my current meditations: People are sick and tired of crappy software. And they aren’t going to take it any more. The proliferation of networked devices — the Internet of Things — is going to mean all kinds of manufacturers traditionally subject to products liability are also software purveyors. If an autonomous car crashes, or a networked toaster catches on fire, you can bet there is going to be product liability. […] I think software liability is inevitable. I think it’s necessary. I think it will make coding more expensive, and more conservative. I think we’ll do a crappy job of it for a really long time.
Large-scale Cluster Management at Google with Borg — Google’s Borg system is a cluster manager that runs hundreds of thousands of jobs, from many thousands of different applications, across a number of clusters, each with up to tens of thousands of machines. […] We present a summary of the Borg system architecture and features, important design decisions, a quantitative analysis of some of its policy decisions, and a qualitative examination of lessons learned from a decade of operational experience with it.
Georgia Sues Carl Malamud (TechDirt) — for copyright infringement… for publishing an official annotated copy of the state's laws. […] the state points directly to the annotated version as the official laws of the state.
A New Artificial Compound Eye (Robohub) — three hexagonal photodetectors arranged in a triangular shape, underneath a single lens. These photodetectors work together and combine perceived changes in structured light (optic flow) to present a 3D image that shows what is moving in the scene, and in which direction the movement is happening.
Google’s Defensive Patent Initiative (TechCrunch) — good article, despite TechCrunch origin. Two-tiered program: give away groups of patents to startups with $500k-$20M in revenue, and sell patents to startups.
Bosun — an open-source, MIT licensed, monitoring and alerting system by Stack Exchange.
The Rise of Computer-Aided Explanation (Michael Nielsen) — Hod Lipson of Columbia University. Lipson and his collaborators have developed algorithms that, when given a raw data set describing observations of a mechanical system, will actually work backward to infer the “laws of nature” underlying those data.

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.

Google Patenting Machine Learning Developments (Reddit) — I am afraid that Google has just started an arms race, which could do significant damage to academic research in machine learning. Now it’s likely that other companies using machine learning will rush to patent every research idea that was developed in part by their employees. We have all been in a prisoner’s dilemma situation, and Google just defected. Now researchers will guard their ideas much more combatively, given that it’s now fair game to patent these ideas, and big money is at stake.
Machine Ethics (Nature) — machine learning ethics versus rule-driven ethics. Logic is the ideal choice for encoding machine ethics, argues Luís Moniz Pereira, a computer scientist at the Nova Laboratory for Computer Science and Informatics in Lisbon. “Logic is how we reason and come up with our ethical choices,” he says. I disagree with his premises.
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.
Souders Joins Speedcurve — During these engagements, I’ve seen that many of these companies don’t have the necessary tools to help them identify how performance is impacting (hurting) the user experience on their websites. There is even less information about ways to improve performance. The standard performance metric is page load time, but there’s often no correlation between page load time and the user’s experience. We need to shift from network-based metrics to user experience metrics that focus on rendering and when content becomes available. That’s exactly what Mark is doing at SpeedCurve, and why I’m excited to join him.
3 Steps for Licensing Your 3D-Printed Stuff (PDF) — this paper is not actually about choosing the right license for your 3D printable stuff (sorry about that). Instead, this paper aims to flesh out a copyright analysis for both physical objects and for the digital files that represent them, allowing you to really understand what parts of your 3D object you are—and are not—licensing. Understanding what you are licensing is key to choosing the right license. Simply put, this is because you cannot license what you do not legally control in the first place. There is no point in considering licenses that ultimately do not have the power to address whatever behavior you’re aiming to control. However, once you understand what it is you want to license, choosing the license itself is fairly straightforward. (via BoingBoing)
The Home and the Mobile Supply Chain (Benedict Evans) — the small hardware start-up, and the cool new gizmos from drones to wearables, are possible because of the low price of components built at the scale required for Apple and other mobile device makers. (via Matt Webb)
Interactive 360-degree Films. From Google (Medium) — you move the camera through a movie shot in 360 degrees, and can choose what you’re looking at through the scene. I can’t wait to try this, it sounds brilliant.
Bitcoin Crackdown — everyone who started exchanges and mutual funds thinking Bitcoin wouldn’t be regulated like a currency is getting an SEC headache.
Connected Choices: How the Internet is Challenging Sovereign Decisions (PDF) — Ultimately, the Internet remains both a global commons and part of each nation’s sovereign infrastructure, and thus activities in cyberspace must continue to navigate two sets of demands: national interests and global interests. […] Political leaders are responsible for articulating a vision and establishing general principles and policies to achieve their goals and, accordingly, are constantly trying to advance their agendas using policy, law, market mechanisms, regulation, standards, and other initiatives. The evidence is clear; you just have to look for it.
