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.

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.

Javascript Helpers, 3D DOM, Hadoop Graph Optimizations, and Future Scenarios

  1. Sugar — a Javascript library that fixes inconsistencies in built-in classes (Strings, Arrays, etc.) and extends them with much-needed time-saving functionality (e.g., automatic iterators over regular expressions; Date creation from strings; binding scopes to functions).
  2. Tilt — clever Firefox plugin that lets you view the DOM on your page in 3D. Excellent for visually understanding the structure and layout of your page. I can’t wait to see the applications of this in debugging and teaching.
  3. Improving Hadoop Efficiency on Graph Data — three techniques: clustering data instead of randomly partitioning across nodes; allowing different data to be replicated differently; graph-optimized storage. (via Big Data)
  4. Learnings from the Long View (PDF) — scenario planning lessons learned from the founder of the field. Most of the scenarios they talk about are near and dear to the O’Reilly heart: smart networks, augmented reality, synthetic biology, energy from bacteria, super macro- and micro-manufacturing.

Printed Toys, Magazines in JS, git push web, Clean Beats More

  1. UK Internet Entrepreneurs (Guardian) — two things stood out for me. (1) A startup focused on 3d printing better dolls for boys and girls. (2) it seems easier to the government to start something new and impose its own vision than it is to understand and integrate with what already exists.
  2. TreeSaver.js — MIT/GPLv2-licensed JavaScript framework for creating magazine-style layouts using standards-compliant HTML and CSS.
  3. Using git to Manage a Web SiteThis page describes how I set things up so that I can make changes live by running just “git push web”.
  4. Strata Data Conference RecapClean data > More Data > Fancy Math — this is the order which makes data easier and better to work with. Clean data will be easier to work with and provide best results. If your data isn’t clean, it is better to have more data than having to resort to fancy math. Using higher order statistical processing, while workable as a last resort, will require longer to develop, difficult algorithms and harder to maintain. So best place to focus is to start with clean data.

Implementing REST, Teaching Exploration, reMAKEing the Enterprise, and Printing Titanium

  1. Implementing RESTThis is a place for exploring aspects of implementing applications using the REST architectural style. This may include statements about existing frameworks and libraries, general discussions about the nature of the style and how it may be expressed and/or encouraged via a programming framework, etc.
  2. When Teaching Restrains Discovery — read about this research (short story: the more specific the skills taught, the less exploratory students were) and think about how we teach people to program, how we teach them the company culture, how we teach them to succeed.
  3. The Maker Generation in the Enterprise (JP Rangaswami) — We have to get away from the idea that knowledge work is smooth and stable and uniform and assembly-line in structure and characteristic. Knowledge work is lumpy. Period. There will be peaks. And there will be troughs. The current thinking appears to go something like this: “If we have troughs it will look like we don’t have enough work to do, so we need to pretend to work. Let’s fill our days up in advance with things that don’t depend on market or customer stimulus, things we can plan well in advance. And let’s call these things meetings. Then we can look busy all the time.” Such thinking has produced some unworthwhile consequences.
  4. i.materialise 3D Printing in TitaniumTitanium’s high heat resistance, high accuracy and unparalleled strength lets designers now make things that before now could only be made by the research and development departments of only the largest corporations in the world. By putting this technology in the public’s hands were democratizing manufacturing and giving you the opportunity to, design and order something this is exactly as you want it to be.

Kinect Hacking, Crowdsource, Lists, and Tablets

  1. 2 Kinects 1 Box (YouTube) — merging data from two Kinects in real time, to get astonishing 3D information. (via Chelfyn Baxter)
  2. Crowdsource is not Open Source (Simon Phipps) — there are some businesses that don’t understand this, and exploit community for their sole benefit in the name of open source. Ignorance of the four freedoms is dangerous.
  3. We Like Lists Before We Don’t Want to Die (Spiegel) — fascinating interview with Umberto Eco. If you interact with things in your life, everything is constantly changing. And if nothing changes, you’re an idiot. (via Aaron Straup Cope on Delicious)
  4. $139.99 Android Tablet at Toys R Ussales of Android tablets (as well as Apple tablets) could help bolster the after-market accessory opportunity for wireless players, including modem makers and wireless operators.

Prison Blogging, 3D Hacks, Budget Simulation, and Enterprise Sales

  1. Between the Bars — snail-mail-to-blogs transcription service for prisoners, to make visible stories that would otherwise be missed. there is a religous program here called Kairo’s in the program inmates are given letters and drawings made by small children not one in that program did not cry, after reading the words of incouragement from those kids. An unmissable reminder of the complexity of human stories, suffering, and situations, the posts range from the banal to the riveting. (via Benjamin Mako Hill)
  2. Kinect Opensource News — a roundup of open source Kinect hacks. I like memo’s gestural interface the best. Impressive stuff for just a few days’ access to the open source drivers. (via Andy Baio)
  3. You Fix The Budget (NY Times) — a simpler version of Budget Hero, which lets you choose policies and see their effect on the deficit. Unlike Budget Hero, the NYT app doesn’t discuss non-deficit consequences of the actions (social consequences, ripple-on economic effects). Like Budget Hero, you can’t add your own policies: you’re forced to choose from the ones presented. Real life is more complex than this simulation, but even something this simple is powerful: by interacting with this, you understand the magnitude of (say) education vs healthcare, and you realize how much of the current debate is froth.
  4. Meet the New Enterprise Customer, a Lot like the Old Enterprise Customer — Ben Horowitz nails the difficulty of selling to the enterprise, and drives a stake through the “they’ll buy our service with their credit cards, like consumers do” myth. xcellent enterprise sales reps will guide a company through their own purchasing processes. Without an enterprise sales rep, many companies literally do not know how to buy new technology products. (via Mike Olson on Twitter)

Facebook Behaviour, Multitouch Modelling, Early Ads, and Gaming Public Transportation

  1. Risk Reduction Strategies on Facebook (danah boyd) — Mikalah uses Facebook but when she goes to log out, she deactivates her Facebook account. She knows that this doesn’t delete the account – that’s the point. She knows that when she logs back in, she’ll be able to reactivate the account and have all of her friend connections back. But when she’s not logged in, no one can post messages on her wall or send her messages privately or browse her content. Two very interesting practices designed to maintain not just some abstract idea of “privacy” but, more important, control.
  2. Beautiful Modeler a software tool for gestural sculpting using a multi-touch controller such as an iPad. (via Andy Baio)
  3. How Telephone Directories Transformed America — this caught my eye: Less than a year after the New Haven District Telephone Company issued its first directory, it issued a second, and that one augmented listings with advertising. (via Pete Warden)
  4. Chromaramaa game that shows you your movements and location as you swipe your Oyster Card in and out of the Tube. Points are awarded for avoiding rush hour, visiting new stations, etc. They say they want to change behaviour, but I don’t believe people ride public transportation to collect points, so they travel when they have to and so won’t change their commute times. Would love to be proven wrong, though. (via Roger Dennis)

Cleaning HTML, 3D Android Home, Autoupdating, Data Refining

  1. Bleach — HTML sanitizer, which some might say is an impossible task.
  2. TAT Home — a gesture-powered 3d home screen for Android.
  3. Omaha — the autoupdater used in Chrome and other Google projects, open sourced.
  4. Google Refine — Freebase GridWorks has new home and new name, with new checkins happening all the time. An excellent ETL tool for figuring out what data you have and getting it into the right format.

Design Principles, Mario AI, Open Source Wave, and 3D Google Earth Sound

  1. Arranging Things: The Rhetoric of Object Placement (Amazon) — […] the underlying principles that govern how Western designers arrange things in three-dimensional compositions. Inspired by Greek and Roman notions of rhetoric […] Koren elucidates the elements of arranging rhetoric that all designers instinctively use in everything from floral compositions to interior decorating. (via Elaine Wherry)
  2. 2010 Mario AI Championship — three tracks: Gameplay, Learning, and Level Generation. Found via Ben Weber’s account of his Level Generation entry. My submission utilizes a multi-pass approach to level generation in which the system iterates through the level several times, placing different types of objects during each pass. During each pass through the level, a subset of each object type has a specific probability of being added to the level. The result is a computationally efficient approach to generating a large space of randomized levels.
  3. Wave in a Box — Google to flesh out existing open source Wave client and server into full “Wave in a Box” app status.
  4. 3D Sound in Google Earth (YouTube) — wow. (via Planet In Action)
