3D Printed Drones, When Pacemakers Attack, N-Gram Updated, and Deanonymizing Datasets

  1. Home-made 3D-Printed Drones — if only they used computer-vision to sequence DNA, they’d be the perfect storm of O’Reilly memes :-)
  2. Hacking Pacemakers For DeathIOActive researcher Barnaby Jack has reverse-engineered a pacemaker transmitter to make it possible to deliver deadly electric shocks to pacemakers within 30 feet and rewrite their firmware.
  3. Google N-Gram Viewer Updated — now with more books, better OCR, parts of speech, and complex queries. e.g., the declining ratio of sex to drugs. Awesome work by Friend of O’Reilly, Jon Orwant.
  4. Deanonymizing Mobility Traces: Using Social Networks as a Side-Channela set of location traces can be deanonymized given an easily obtained social network graph. […] Our experiments [on standard datasets] show that 80% of users are identified precisely, while only 8% are identified incorrectly, with the remainder mapped to a small set of users.

Drone Conflict, 3D Scanning Booths, Bitcoin Consensus, and Moar Coders

  1. Beware the Drones (Washington Times) — the temptation to send difficult to detect, unmanned aircraft into foreign airspace with perceived impunity means policymakers will naturally incline towards aggressive use of drones and hyperactive interventionism, leading us to a future that is ultimately plagued by more, not less warfare and conflict. This. Also, what I haven’t seen commented on with the Israeli air force shooting down a (presumably Hezbollah) drone: low cost of drones vs high cost of maintaining an air force to intercept, means this is asymmetric unmanned warfare.
  2. Scanbooth (github) — a collection of software for running a 3D scanning booth. Greg Borenstein said to me, “we need tools to scan and modify before 3D printing can take off.” (via Jeremy Herrman)
  3. Bitcoin’s Value is Decentralization (Paul Bohm) — Bitcoin isn’t just a currency but an elegant universal solution to the Byzantine Generals’ Problem, one of the core problems of reaching consensus in Distributed Systems. Until recently it was thought to not be practically solvable at all, much less on a global scale. Irrespective of its currency aspects, many experts believe Bitcoin is brilliant in that it technically made possible what was previously thought impossible. (via Mike Loukides)
  4. Blue Collar Coder (Anil Dash) — I am proud of, and impressed by, Craigslist’s ability to serve hundreds of millions of users with a few dozen employees. But I want the next Craigslist to optimize for providing dozens of jobs in each of the towns it serves, and I want educators in those cities to prepare young people to step into those jobs. Time for a Massively Multiplayer Online Economy, as opposed to today’s fun economic games of Shave The Have-Nots and Race To The Oligarchy.

3D Parts, ISP Surveillance, Sensors for Espionage, and Typed Javascript

  1. Print Your Own 3D Parts (Wired) — Teenage Engineering, makers of a popular synthesizer known as the OP-1, posted the 3-D design files of various components on digital object repository Shapeways, and is instructing 3-D printer-equipped users to print them out instead of buying them.
  2. Legacy Media Demanding Surveillance In ISPsmusic rights groups including the Recording Industry Association of Japan say they have developed a system capable of automatically detecting unauthorized music uploads before they even hit the Internet. But to do that they need to be able to spy on Internet users’ connections and compare data being transferred with digital fingerprints held in an external database. That can only be achieved with the assistance of Internet service providers who would be asked to integrate the system deeply into their networks. It’s Japan for now …
  3. Sensors for Industrial Espionage (NPR) — Genscape also places electromagnetic monitors beneath the power lines running into the Cushing tank farms to measure their power usage. This gives them an idea of how much oil is being pumped into and out of Cushing.
  4. TypeScript — Apache2 licensed typed superset of JavaScript that compiles to plain JavaScript.

Rapture of the Nerds, Amazon Maps API, 3D Printer Queues, and the New Aesthetic

  1. The Rapture of the Nerds (Charlie Stoss, Cory Doctorow) — available for download and purchase under a CC-A-NC-ND license.
  2. Amazon Maps API — if there is an API layer of general use to developers, Amazon will build it. They want to be the infrastructure for the web. Tim identified “the Internet Operating System”, and Amazon figured out how to put a pricetag on every syscall.
  3. Hoektronics — open source 3d printer queue management. (via Daniel Suarez)
  4. The Machine Gaze (Will Wiles) — Converging, leapfrogging technologies evoke new emotional responses within us, responses that do not yet have names. (via James Bridle)

Programming Patterns, Limits of Observation, Surviving Transparency, 3D Printing Sounds

  1. Patterns for Research in Machine Learning — every single piece of advice should be tattooed under the eyelids of every beginning programmer, regardless of the field.
  2. Milton Friedman’s ThermostatEverybody knows that if you press down on the gas pedal the car goes faster, other things equal, right? And everybody knows that if a car is going uphill the car goes slower, other things equal, right? But suppose you were someone who didn’t know those two things. And you were a passenger in a car watching the driver trying to keep a constant speed on a hilly road. You would see the gas pedal going up and down. You would see the car going downhill and uphill. But if the driver were skilled, and the car powerful enough, you would see the speed stay constant. So, if you were simply looking at this particular “data generating process”, you could easily conclude: “Look! The position of the gas pedal has no effect on the speed!”; and “Look! Whether the car is going uphill or downhill has no effect on the speed!”; and “All you guys who think that gas pedals and hills affect speed are wrong!” (via Dr Data’s Blog)
  3. Transparency Doesn’t Kill Kittens (O’Reilly Radar) — Atul Gawande says, cystic fibrosis … had data for 40 years on the performance of the centers around the country that take care of kids with cystic fibrosis. They shared the data privately […] They just told you where you stood relative to everybody else and they didn’t make that information public. About four or five years ago, they began making that information public. It’s now available on the Internet. You can see the rating of every center in the country for cystic fibrosis. Several of the centers had said, “We’re going to pull out because this isn’t fair.” Nobody ended up pulling out. They did not lose patients in hoards and go bankrupt unfairly. They were able to see from one another who was doing well and then go visit and learn from one and other.

Visual Strategies, Copyright Robots, Fast Small 3D Printing, and Javascript Dataviz

  1. Visual Strategies — book of useful tips for improving visualisations, described as “a useful Tufte”. (via NY Times)
  2. Copyright Enforcement Bots Killed Hugo Streaming (io9) — automated content policing ‘bots killed the live stream, and uStream wouldn’t bring it back. This is the problem with automated enforcement: bots can’t tell all permitted uses, let alone fair use.
  3. High Resolution 3D Printer — 5m/s at micrometer precision. Looking forward to my nanoscale RepRap.
  4. Javascript Data Visualization Tools — elegantly-presented selection of tools for dataviz in Javascript. (via Javascript Weekly)

DIY Medical Devices, 3D Exoskeletal Arms, Scientific Data Depository, and Zombees

  1. Why Toys Make Good Medical Devices (YouTube) — Jose Gomez-Marquez profiled by CNN. His group at MIT is Little Devices.
  2. 3D Printed Exoskeletal Arms for Little Girlresearchers at a Delaware hospital 3D printed a durable custom device with the tiny, lightweight custom parts she needed. Good for iterations, replacements, and an astonishingly high number of “awww” moments in the video.
  3. Figshareallows researchers to publish all of their data in a citable, searchable and sharable manner. All data is persistently stored online under the most liberal Creative Commons licence, waiving copyright where possible. figshare was started by a frustrated Imperial College PhD student as a way to disseminate all research outputs and not just static images through traditional academic publishing. It is now supported by Digital Science, a Macmillan Publishers company.
  4. Zombeeshoney bees that have been parasitized by the Zombie Fly Apocephalus borealis. Fly-parasitized honey bees become “ZomBees” showing the “zombie-like behavior” of leaving their hives at night on “a flight of the living dead.” See also NPR interview.

Urban Design, Vehicle Interfaces, Maldrones, and Cloud Translation

  1. Christchurch’s Shot at Being Innovation Central (Idealog) — Christchurch, rebuilding a destroyed CBD after earthquakes, has released plans for the new city. I hope there’s budget for architects and city developers to build visible data, sensors, etc. so the Innovation Precinct doesn’t become the Tech Ghetto.
  2. Torque Pro (Google Play Store) — a vehicle / car performance/diagnostics tool and scanner that uses an OBD II Bluetooth adapter to connect to your OBD2 engine management/ECU. Can lay out out your dashboards, track performance via GPS, and more. (via Steve O’Grady)
  3. Drone Pilots (NY Times) — at the moment, the stories are all about the technology helping our boys valiantly protecting the nation. Things will get interesting when the new technology is used against us (we just saw the possibility of this with 3D printing guns). (via Dave Pell)
  4. Avalon (GitHub) — A cloud based translation and localization utility for Python which combines human and machine translation. There’s also a how-to. (via Brian McConnell)

Torturing HTTP, Twitter Business, Mobile Setup, and 3D Printing Olympic Gold

  1. pathodA pathological HTTP daemon for testing and torturing client software. (via Hacker News)
  2. A Walk Through Twitter’s Walled Garden (The Realtime Report) — nice breakdown of Twitter’s business model choice and consequences. Twitter wants you to be able to see the pictures and read the articles shared in your its Tweets, without leaving the garden. Costolo told the Los Angeles Times that “Twitter is heading in a direction where its 140-character messages are not so much the main attraction but rather the caption to other forms of content.” (You know all the traffic that Twitter’s been driving to web sites? Don’t count on it being there next year.) (via Jim Stogdill)
  3. My Computing Environment (Jesse Vincent) — already have a set of those gloves on order.
  4. How Speedo Created a Record-Breaking Swimsuit (Scientific American) — A new 3-D printer at Aqualab fabricated prototypes of the cap and goggles for testing within hours, rather than sending drawings to a manufacturer and waiting weeks or months. “In the past we couldn’t do many changes to the original design,” Santry says. “With this process, we completely revolutionized the goggle from scratch.” (via Eric Ries)

Answers not Maps, Government in Web Sites, Future of Manufacturing, The .000063% Influencers

  1. The Future of a Map is Its Information (The Atlantic) — maps are how we display data when we, the brain, wish to answer a question. Technology is rapidly expanding the questions we don’t need to look at a map to answer: directions, weather forecasts, dining …. (via Flowing Data)
  2. Governments Don’t Have Websites, Governments Are Websites (MySociety) — the best part about MySociety’s recent funding is that Tom Steinberg is blogging more. The majority of citizens don’t have deep, all encompassing, everyday interactions with the state – at most they drop their kids at school every day, or visit the GP a few times a year. That’s as physically close as they get. To these people, interacting with government already feels somewhat like interacting with Amazon. It sends them benefits, passports, recycling bins, car tax disks from mysterious dispatch offices and it demands money and information in return. The difference is in emotional tone – the Amazon online interactions tend to be seamless, the government online interactions either painful or impossible – time to pick up the phone.
  3. The Future of Manufacturing is America not China (Foreign Policy) — robots + AI + low-cost or shared public manufacturing facilities = the future of manufacturing.
  4. Captured America (The Atlantic) — Larry Lessig observes the tilted playing field responsible for America’s inability to govern itself: A tiny number of Americans — .26 percent — give more than $200 to a congressional campaign. .05 percent give the maximum amount to any congressional candidate. .01 percent give more than $10,000 in any election cycle. And .000063 percent — 196 Americans — have given more than 80 percent of the super-PAC money spent in the presidential elections so far.
