Artificial Labour, Flexible Circuits, Vanishing Business Sexts, and Themal Imaging

  1. Artificial Labour and Ubiquitous Interactive Machine Learning (Greg Borenstein) — in which design fiction, actual machine learning, legal discovery, and comics meet. One of the major themes to emerge in the 2H2K project is something we’ve taken to calling “artificial labor”. While we’re skeptical of the claims of artificial intelligence, we do imagine ever-more sophisticated forms of automation transforming the landscape of work and economics. Or, as John puts it, robots are Marxist.
  2. Clear Flexible Circuit on a Contact Lens (Smithsonian) — ends up about 1/60th as thick as a human hair, and is as flexible.
  3. Confide (GigaOm) — Enterprise SnapChat. A Sarbanes-Oxley Litigation Printer. It’s the Internet of Undiscoverable Things. Looking forward to Enterprise Omegle.
  4. FLIR One — thermal imaging in phone form factor, another sensor for your panopticon. (via DIY Drones)

Cognition as a Service, Levy on NSA, SD-Sized Computer, and Learning Research

  1. Launching the Wolfram Connected Devices Project — Wolfram Alpha is cognition-as-a-service, which they hope to embed in devices. This data-powered Brain-in-the-Cloud play will pit them against Google, but G wants to own the devices and the apps and the eyeballs that watch them … interesting times ahead!
  2. How the USA Almost Killed the Internet (Wired) — “At first we were in an arms race with sophisticated criminals,” says Eric Grosse, Google’s head of security. “Then we found ourselves in an arms race with certain nation-state actors [with a reputation for cyberattacks]. And now we’re in an arms race with the best nation-state actors.”
  3. Intel Edison — SD-card sized, with low-power 22nm 400MHz Intel Quark processor with two cores, integrated Wi-Fi and Bluetooth.
  4. N00b 2 L33t, Now With Graphs (Tom Stafford) — open science research validating many of the findings on learning, tested experimentally via games. In the present study, we analyzed data from a very large sample (N = 854,064) of players of an online game involving rapid perception, decision making, and motor responding. Use of game data allowed us to connect, for the first time, rich details of training history with measures of performance from participants engaged for a sustained amount of time in effortful practice. We showed that lawful relations exist between practice amount and subsequent performance, and between practice spacing and subsequent performance. Our methodology allowed an in situ confirmation of results long established in the experimental literature on skill acquisition. Additionally, we showed that greater initial variation in performance is linked to higher subsequent performance, a result we link to the exploration/exploitation trade-off from the computational framework of reinforcement learning.

3D Motion Tracking, Linux of Things, Techno Panics, and Great CS Papers

  1. Witracktracks the 3D motion of a user from the radio signals reflected off her body. It works even if the person is occluded from the WiTrack device or in a different room. WiTrack does not require the user to carry any wireless device, yet its accuracy exceeds current RF localization systems, which require the user to hold a transceiver. It transmits wireless signals whose power is 100 times smaller than Wi-Fi and 1000 times smaller than cellphone transmissions.
  2. A Linux Christmas — Linux drives pretty much all of Amazon’s top-selling consumer electronics.
  3. Techno Panic Timeline — chart from Exposing the War on Fun showing the fears of technology from 1493 to the modern day.
  4. Best Paper Awards in CS Since 1996 (Jeff Huang) — fantastic resource for your holiday reading.

Inside the Nest Protect, Log Structures, Predictions, and In-Memory Data Cubes

  1. Nest Protect Teardown (Sparkfun) — initial teardown of another piece of domestic industrial Internet.
  2. LogsThe distributed log can be seen as the data structure which models the problem of consensus. Not kidding when he calls it “real-time data’s unifying abstraction”.
  3. Mining the Web to Predict Future Events (PDF) — Mining 22 years of news stories to predict future events. (via Ben Lorica)
  4. Nanocubesa fast datastructure for in-memory data cubes developed at the Information Visualization department at AT&T Labs – Research. Nanocubes can be used to explore datasets with billions of elements at interactive rates in a web browser, and in some cases it uses sufficiently little memory that you can run a nanocube in a modern-day laptop.

  1. SAMOA — Yahoo!’s distributed streaming machine learning (ML) framework that contains a programming abstraction for distributed streaming ML algorithms. (via Introducing SAMOA)
  2. madliban open-source library for scalable in-database analytics. It provides data-parallel implementations of mathematical, statistical and machine-learning methods for structured and unstructured data.
  3. Data Portraits: Connecting People of Opposing Views — Yahoo! Labs research to break the filter bubble. Connect people who disagree on issue X (e.g., abortion) but who agree on issue Y (e.g., Latin American interventionism), and present the differences and similarities visually (they used wordclouds). Our results suggest that organic visualisation may revert the negative effects of providing potentially sensitive content. (via MIT Technology Review)
  4. Disguise Detection — using Raspberry Pi, Arduino, and Python.

Hardware Market, Bio Patent History Lesson, Multiplayer Mathematics, and TV Numbers (Down)

  1. Huaqiang Bei Map for Makers — excellent resource for visitors to an iconic huge electronics market in Shenzhen. (via Bunnie Huang)
  2. A 16th Century Dutchman Can Tell us Everything We Need to Know about GMO PatentsThere’s nothing wrong with this division of labor, except that it means that fewer people are tinkering. We’ve centralized the responsibility for agricultural innovation among a few engineers, even fewer investors, and just a handful of corporations. (and check out the historical story—it’s GREAT)
  3. Polymath Projects — massively multiplayer mathematical proving ground. Let the “how many mathematicians does it take” jokes commence. (via Slashdot)
  4. Stats on Dying TV — like a Mary Meeker preso, accumulation of evidence that TV screens and cable subscriptions are dying and mobile-consumed media are taking its place.

ISS Malware, Computational Creativity, Happy Birthday Go, Built Environment for Surveillance

  1. ISS Enjoys Malware — Kaspersky reveals ISS had XP malware infestation before they shifted to Linux. The Gravity movie would have had more registry editing sessions if the producers had cared about FACTUAL ACCURACY.
  2. Big Data Approach to Computational Creativity (Arxiv) — although the “results” are a little weak (methodology for assessing creativity not described, and this sadly subjective line “professional chefs at various hotels, restaurants, and culinary schools have indicated that the system helps them explore new vistas in food”), the process and mechanism are fantastic. Bayesian surprise, crowdsourced tagged recipes, dictionaries of volatile compounds, and more. (via MIT Technology Review)
  3. Go at 4 — recapping four years of Go language growth.
  4. Las Vegas Street Lights to Record Conversations (Daily Mail) — The wireless, LED lighting, computer-operated lights are not only capable of illuminating streets, they can also play music, interact with pedestrians and are equipped with video screens, which can display police alerts, weather alerts and traffic information. The high tech lights can also stream live video of activity in the surrounding area. Technology vendor is Intellistreets. LV says, Right now our intention is not to have any cameras or recording devices. Love that “right now”. Can’t wait for malware to infest it.
