Google’s Seven Robotics Companies (IEEE) — The seven companies are capable of creating technologies needed to build a mobile, dexterous robot. Mr. Rubin said he was pursuing additional acquisitions. Rundown of those seven companies.
Hebel (Github) — GPU-Accelerated Deep Learning Library in Python.
What We Learned Open Sourcing — my eye was caught by the way they offered APIs to closed source code, found and solved performance problems, then open sourced the fixed code.
Collaboration, Stars, and the Changing Organization of Science: Evidence from Evolutionary Biology — The concentration of research output is declining at the department level but increasing at the individual level. [...] We speculate that this may be due to changing patterns of collaboration, perhaps caused by the rising burden of knowledge and the falling cost of communication, both of which increase the returns to collaboration. Indeed, we report evidence that the propensity to collaborate is rising over time. (via Sciblogs)
The Virtuous Pipeline of Code (Public Resource) — Chicago partnering with Public Resource to open its legal codes for good. “This is great! What can we do to help?” Bravo Chicago, and everyone else—take note!
Smithsonian’s 3D Data — models of 21 objects, from a gunboat to the Wright Brothers’ plane, to a wooly mammoth skeleton, to Lincoln’s life masks. I wasn’t able to find a rights statement on the site which explicitly governed the 3D models. (via Smithsonian Magazine)
Anki’s Robot Cars (Xconomy) — The common characteristics of these future products, in Sofman’s mind: “Relatively simple and elegant hardware; incredibly complicated software; and Web and wireless connectivity to be able to continually expand the experience over time.” (via Slashdot)
An Empirical Evaluation of TCP Performance in Online Games — We show that because TCP was originally designed for unidirectional and network-limited bulk data transfers, it cannot adapt well to MMORPG traffic. In particular, the window-based congestion control and the fast retransmit algorithm for loss recovery are ineffective. Furthermore, TCP is overkill, as not every game packet needs to be transmitted in a reliably and orderly manner. We also show that the degraded network performance did impact users’ willingness to continue a game.

Business as Usual in the Innovation Industry — the only thing worse than business plan contests for startups is innovation wankfests for small arts groups. [T]he vast majority of small and mid-sized arts organizations are not broken so much as they are in a constant state of precarity that could largely be addressed by reliable funding streams to support general operations and less onerous grant application processes that would allow them to focus more on delivering services and less on raising money. Hear! (via Courtney Johnston)
Driverless Cars Are Further Away Than You Think (MIT Technology Review) — nice roundup of potential benefits. experiments involving modified road vehicles conducted by Volvo and others in 2011 suggest that having vehicles travel in high-speed automated “platoons,” thereby reducing aerodynamic drag, could lower fuel consumption by 20 percent. And an engineering study published last year concluded that automation could theoretically allow nearly four times as many cars to travel on a given stretch of highway.
Steve Yegge on GROK (YouTube) — The Grok Project is an internal Google initiative to simplify the navigation and querying of very large program source repositories. We have designed and implemented a language-neutral, canonical representation for source code and compiler metadata. Our data production pipeline runs compiler clusters over all Google’s code and third-party code, extracting syntactic and semantic information. The data is then indexed and served to a wide variety of clients with specialized needs. The entire ecosystem is evolving into an extensible platform that permits languages, tools, clients and build systems to interoperate in well-defined, standardized protocols.
Deep Learning for Semantic Analysis — When trained on the new treebank, this model outperforms all previous methods on several metrics. It pushes the state of the art in single sentence positive/negative classification from 80% up to 85.4%. The accuracy of predicting fine-grained sentiment labels for all phrases reaches 80.7%, an improvement of 9.7% over bag of features baselines. Lastly, it is the only model that can accurately capture the effect of contrastive conjunctions as well as negation and its scope at various tree levels for both positive and negative phrases.

pineapple.io — attempt to crowdsource rankings for tutorials for important products, so you’re not picking your way through Google search results littered with tutorials written by incompetent illiterates for past versions of the software.

Why Can’t My Computer Understand Me (New Yorker) — using anaphora as the basis of an intelligence test, as example of what AI should be striving for. It’s not just that contemporary A.I. hasn’t solved these kinds of problems yet; it’s that contemporary A.I. has largely forgotten about them. In Levesque’s view, the field of artificial intelligence has fallen into a trap of “serial silver bulletism,” always looking to the next big thing, whether it’s expert systems or Big Data, but never painstakingly analyzing all of the subtle and deep knowledge that ordinary human beings possess. That’s a gargantuan task— “more like scaling a mountain than shoveling a driveway,” as Levesque writes. But it’s what the field needs to do.
Quantum Information (New Scientist) — a gentle romp through the possible and the actual for those who are new to the subject.
Ambient Backscatter (PDF) — a new communication primitive where devices communicate by backscattering ambient RF signals. Our design avoids the expensive process of generating radio waves; backscatter communication is orders of magnitude more power-efﬁcient than traditional radio communication. (via Hacker News)
Top Free-to-Play Monetization Tricks (Gamasutra) — amazingly evil ways that free games lure you into paying. At this point the user must choose to either spend about $1 or lose their rewards, lose their stamina (which they could get back for another $1), and lose their progress. To the brain this is not just a loss of time. If I spend an hour writing a paper and then something happens and my writing gets erased, this is much more painful to me than the loss of an hour. The same type of achievement loss is in effect here. Note that in this model the player could be defeated multiple times in the boss battle and in getting to the boss battle, thus spending several dollars per dungeon.
