Mozilla Payments, Firefox Cleans Cookies, Lost: One Web Please Return to Those Who Love It, and 3D from Spaaaaace

  1. mozpaya JavaScript API inspired by google.payments.inapp.buy() but modified for things like multiple payment providers and carrier billing. When a web app invokes navigator.mozPay() in Firefox OS, the device shows a secure window with a concise UI. After authenticating, the user can easily charge the payment to her mobile carrier bill or credit card. When completed, the app delivers the product. Repeat purchases are quick and easy.
  2. Firefox Looks Like it Will Reject Third-Party Cookies (ComputerWorld) — kudos Mozilla! Now we’ll see whether such a cookie policy does deliver a better user experience. Can privacy coexist with a good user experience? Answers on a tweet, please, to @radar.
  3. How We Lost the Web (Anil Dash) — excellent talk about the decreasing openness and vanishing shared culture of the web. See also David Weinberger’s transcription.
  4. 3D From Space Shuttle Footage? — neat idea! Filming in 3D generally requires two cameras that are separated laterally, to create the parallax effected needed for stereoscopic vision. Fortunately, videos shot from Earth orbit can be converted to 3D without a second camera, because the camera is constantly in motion.

Island Traps, Apolitical Technology, 3D Printing Patent Suits, and Disk-Based Graph Tool

  1. Trap Island — island on most maps doesn’t exist.
  2. Why I Work on Non-Partisan Tech (MySociety) — excellent essay. Obama won using big technology, but imagine if that effort, money, and technique were used to make things that were useful to the country. Political technology is not gov2.0.
  3. 3D Printing Patent Suits (MSNBC) — notable not just for incumbents keeping out low-cost competitors with patents, but also (as BoingBoing observed) Many of the key patents in 3D printing start expiring in 2013, and will continue to lapse through ’14 and ’15. Expect a big bang of 3D printer innovation, and massive price-drops, in the years to come. (via BoingBoing)
  4. GraphChican run very large graph computations on just a single machine, by using a novel algorithm for processing the graph from disk (SSD or hard drive). Programs for GraphChi are written in the vertex-centric model, proposed by GraphLab and Google’s Pregel. GraphChi runs vertex-centric programs asynchronously (i.e changes written to edges are immediately visible to subsequent computation), and in parallel. GraphChi also supports streaming graph updates and removal of edges from the graph.

Vannevar Bush, Topic Transparency, Ancient Maps, and Concussion Sensors

  1. As We May Think (Vannevar Bush) — incredibly prescient piece he wrote for The Atlantic in 1945.
  2. Transparency and Topic Models (YouTube) — a talk from DataGotham 2012, by Hanna Wallach. She uses latent Dirichlet allocation topic models to mine text data in declassified documents where the metadata are useless. She’s working on predicting classification durations (AWESOME!). (via Matt Biddulph)
  3. Slippy Map of the Ancient World — this. is. so. cool!
  4. Technology in the NFLX2IMPACT’s Concussion Management System (CMS) is a great example of this trend. CMS, when combined with a digital mouth guard, also made by X2, enables coaches to see head impact data in real-time and asses concussions through monitoring the accelerometers in a players mouth guard. That data helps teams to decide whether to keep a player on the field or take them off for their own safety. Insert referee joke here.

LIDAR for Mapping, Homebrew CoverFlow, Browser Exploitation, and Dependency Injection

  1. Wearable LIDAR Sensors for Mapping (BBC) — made at MIT from commodity hardware, The system is still a prototype, but when tested in closed hallways without any Global Positioning System (GPS) signal, it was able to precisely map the environment as the user was moving through it. (via Andrew Turner)
  2. Coverflow (Github) — an iPhone project implementing Coverflow using iOS 6 UICollectionViews and a custom UICollectionViewLayout […] I think the interpolation technique I use is rather neat and allows you to easily adjust the layout and behavior of the layout. (via Jonathan Wight)
  3. BEEF ProjectThe Browser Exploitation Framework. It is a penetration testing tool that focuses on the web browser.
  4. Dagger (Github) — A fast dependency injector for Android and Java. (via Chris Aniszczyk)

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)

NeoVictorian Computing, Participatory Budgeting, Micro Thrusters, and Geopositioning Accuracy

  1. NeoVictorian Computing (Mark Bernstein) — read this! I think we all woke up one day to find ourselves living in the software factory. The floor is hard, from time to time it gets very cold at night, and they say the factory is going to close and move somewhere else. […] The Arts & Crafts movement failed in consumer goods, but it could succeed in software. (via James Governor)
  2. Participatory Budgetingresearch shows participation is more effective than penalties in taxation compliance. Participation is more effective than penalties in almost everything.
  3. MIT-Developed Microthrustersa flat, compact square — much like a computer chip — covered with 500 microscopic tips that, when stimulated with voltage, emit tiny beams of ions. Together, the array of spiky tips creates a small puff of charged particles that can help propel a shoebox-sized satellite forward. You say satellite, but it’s only a matter of time until this powers a DIY RC rocket with a camera payload. (via Hacker News)
  4. Yelp Checkins to Measure Geopositioning Accuracy Across PhonesBy analyzing millions of data points, we can easily see how, on average, different platforms perform. iPhones consistently have the most accurate positioning, with a fairly small accuracy radius. Android phones are often inaccurate, but reliably reported that inaccuracy. And finally, iPods using Wi-Fi positioning proved the least accurate and usually reported incorrect accuracy radii.

Reading Minds, Satellites in the Cloud, Units for Risk, and Valuing Autism

  1. Reconstructing Visual Experiences (PDF) — early visual areas represent the information in movies. To demonstrate the power of our approach, we also constructed a Bayesian decoder by combining estimated encoding models with a sampled natural movie prior. The decoder provides remarkable reconstructions of the viewed movies. These results demonstrate that dynamic brain activity measured under naturalistic conditions can be decoded using current fMRI technology.
  2. Earth Engine — satellite imagery and API for coding against it, to do things like detecting deforestation, classifying land cover, estimating forest biomass and carbon, and mapping the world’s roadless areas.
  3. Microlives — 30m of your life expectancy. Here are some things that would, on average, cost a 30-year-old man 1 microlife: Smoking 2 cigarettes; Drinking 7 units of alcohol (eg 2 pints of strong beer); Each day of being 5 Kg overweight. A chest X-ray will set a middle-aged person back around 2 microlives, while a whole body CT-scan would weigh in at around 180 microlives.
  4. Autistics Need Opportunities More Than Treatment — Laurent gave a powerful talk at Sci Foo: if the autistic brain is better at pattern matching, find jobs where that’s useful. Like, say, science. The autistic woman who was delivering mail became a research assistant in his lab, now has papers galore to her name for original research.

Creative Business, News Design, Google Earth Glitches, and Data Distortion

  1. Patton Oswalt’s Letters to Both SidesYou guys need to stop thinking like gatekeepers. You need to do it for the sake of your own survival. Because all of us comedians after watching Louis CK revolutionize sitcoms and comedy recordings and live tours. And listening to “WTF With Marc Maron” and “Comedy Bang! Bang!” and watching the growth of the UCB Theatre on two coasts and seeing careers being made on Twitter and Youtube. Our careers don’t hinge on somebody in a plush office deciding to aim a little luck in our direction. (via Jim Stogdill)
  2. Headliner — interesting Guardian experiment with headlines and presentation. As always, reading the BERG designers’ notes are just as interesting as the product itself. E.g., how they used computer vision to find faces and zoom in on them to make articles more attractive to browsing readers.
  3. Google Earth Glitches — where 3d maps and aerial imagery don’t match up. (via Beta Knowledge)
  4. Campbell’s LawThe more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor. (via New York Times)

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.

Talkative Virus Writer, QR Codes, Digital Reconstruction, and Renewable Energy

  1. Researcher Chats To Hacker Who Created The Virus He’s ResearchingChicken: I didn’t know you can see my screen. Hacker: I would like to see your face, but what a pity you don’t have a camera.
  2. Economist on QR CodesThree-quarters of American online retailers surveyed by Forrester, a research firm, use them. In April nearly 20% of smartphone users in America scanned one, up from 14% in May last year.
  3. Reconstructing the Ruins of Warsaw — what an amazing accomplishment!
  4. The Great German Energy Experiment (Technology Review) — political will: the risk and the successes. Certainly a huge gulf between Germany and America in where they are, and political will to be more renewable.
