The Many Facades of DRM (PDF) — Modular software systems are designed to be broken into independent pieces. Each piece has a clear boundary and well-defined interface for ‘hooking’ into other pieces. Progress in most technologies accelerates once systems have achieved this state. But clear boundaries and well-defined interfaces also make a technology easier to attack, break, and reverse-engineer. Well-designed DRMs have very fuzzy boundaries and are designed to have very non-standard interfaces. The examples of the uglified DRM code are inspiring.
DPDK — a set of libraries and drivers for fast packet processing […] to: receive and send packets within the minimum number of CPU cycles (usually less than 80 cycles); develop fast packet capture algorithms (tcpdump-like); run third-party fast path stacks.
A Worm’s Mind in a Lego Body — the c. elegans worm’s 302 neurons has been sequenced, modelled in open source code, and now hooked up to a Lego robot. It is claimed that the robot behaved in ways that are similar to observed C. elegans. Stimulation of the nose stopped forward motion. Touching the anterior and posterior touch sensors made the robot move forward and back accordingly. Stimulating the food sensor made the robot move forward. There is video.
Apollo: Amazon’s Deployment Engine — Apollo will stripe the rolling update to simultaneously deploy to an equivalent number of hosts in each location. This keeps the fleet balanced and maximizes redundancy in the case of any unexpected events. When the fleet scales up to handle higher load, Apollo automatically installs the latest version of the software on the newly added hosts. Lust.
The Dark Market for Personal Data (NYTimes) — can buy lists of victims of sexual assault, of impulse buyers, of people with sexually transmitted disease, etc. The cost of a false-positive when those lists are used for marketing is less than the cost of false-positive when banks use the lists to decide whether you’re a credit risk. The lists fall between the cracks in privacy legislation; essentially, the compilation and use of lists of people are unregulated territory.
Collaborative Filtering at LinkedIn (PDF) — This paper presents LinkedIn’s horizontal collaborative filtering infrastructure, known as browsemaps. Great lessons learned, including context and presentation of browsemaps or any recommendation is paramount for a truly relevant user experience. That is, design and presentation represents the largest ROI, with data engineering being a second, and algorithms last. (via Greg Linden)
Engineer Sees Big Possibilities in Micro-robots, Including Programmable Bees (National Geographic) — He and fellow researchers devised novel techniques to fabricate, assemble, and manufacture the miniature machines, each with a housefly-size thorax, three-centimeter (1.2-inch) wingspan, and weight of just 80 milligrams (.0028 ounces). The latest prototype rises on a thread-thin tether, flaps its wings 120 times a second, hovers, and flies along preprogrammed paths. (via BoingBoing)
cuDNN — NVIDIA’s library of primitives for deep neural networks (on GPUS, natch). Not open source (registerware).
Analysing Trends in Silk Road 2.0 — If, indeed every sale can map to a transaction, some vendors are doing huge amounts of business through mail order drugs. While the number is small, if we sum up all the product reviews x product prices, we get a huge number of USD $20,668,330.05. REMEMBER! This is on Silk Road 2.0 with a very small subset of their entire inventory. A peek into a largely invisible economy.
Failing at Microservices — deconstructed a failed stab at microservices. Category three engineers also presented a significant problem to our implementation. In many cases, these engineers implemented services incorrectly; in one example, an engineer had literally wrapped and hosted one microservice within another because he didn’t understand how the services were supposed to communicate if they were in separate processes (or on separate machines). These engineers also had a tough time understanding how services should be tested, deployed, and monitored because they were so used to the traditional “throw the service over the fence”to an admin approach to deployment. This basically lead to huge amounts of churn and loss of productivity.
Viv — another step in the cognition race. Wolfram Alpha was first out the gate, but Watson, Viv, and others are hot on heels of being able to parse complex requests, then seek and use information to fulfil them.
Universal Mobile Electrochemical Detector Designed for Use in Resource-limited Applications (PNAS) — $35 handheld sensor with mobile phone connection. The electrochemical methods that we demonstrate enable quantitative, broadly applicable, and inexpensive sensing with flexibility based on a wide variety of important electroanalytical techniques (chronoamperometry, cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, and potentiometry), each with different uses. Four applications demonstrate the analytical performance of the device: these involve the detection of (i) glucose in the blood for personal health, (ii) trace heavy metals (lead, cadmium, and zinc) in water for in-field environmental monitoring, (iii) sodium in urine for clinical analysis, and (iv) a malarial antigen (Plasmodium falciparum histidine-rich protein 2) for clinical research.

panamax.io — containerized app creator with an open-source app marketplace hosted in GitHub. Panamax provides a friendly interface for users of Docker, Fleet & CoreOS. With Panamax, you can easily create, share and deploy any containerized app no matter how complex it might be.
Material Design in the Google I/O App (Medium) — steps through design thinking as they put Google’s new design metaphor in place. I’ve been chewing on material design. It brings an internal consistency and logic to the Android world that Apple’s iOS and OS X visual worlds have been losing over the years. How long until web users expect this consistency too?
Stewart and Slack (Wired) — profile of Foo Stewart Butterfield and his shiny Slack startup.
Offline First is the New Mobile First — Luke Wroblewski’s notes from John Allsopp’s talk about “Breaking Development” in Nashville. Offline technologies don’t just give us sites that work offline, they improve performance, and security by minimizing the need for cookies, http, and file uploads. It also opens up new possibilities for better user experiences.
Winograd Schemas as Alternative to Turing Test (IEEE) — specially constructed sentences that are surface ambiguous and require deeper knowledge of the world to disambiguate, e.g. “Jim comforted Kevin because he was so upset. Who was upset?”. Our WS [Winograd schemas] challenge does not allow a subject to hide behind a smokescreen of verbal tricks, playfulness, or canned responses. Assuming a subject is willing to take a WS test at all, much will be learned quite unambiguously about the subject in a few minutes. (that last from the paper on the subject)
Reclaiming Your Nest (Forbes) — Like so many connected devices, Nest devices regularly report back to the Nest mothership with usage data. Over a month-long period, the researchers’ device sent 32 MB worth of information to Nest, including temperature data, at-rest settings, and self-entered information about the home, such as how big it is and the year it was built. “The Nest doesn’t give us an option to turn that off or on. They say they’re not going to use that data or share it with Google, but why don’t they give the option to turn it off?” says Jin. Jailbreak your Nest (technique to be discussed at Black Hat), and install less chatty software. Loose Lips Sink Thermostats.
