- Trap Island — island on most maps doesn’t exist.
- 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.
- 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)
- GraphChi — can 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.
ENTRIES TAGGED "3d printing"
At its best, 3D printing can make us more human by making us whole.
Island Traps, Apolitical Technology, 3D Printing Patent Suits, and Disk-Based Graph Tool
3D Printing Booth, Crowdsourcing Nanoscience, Mobile Numbers, and Web Techniques
- 3D Printing Photobooth Opening in Japan (io9) — A technician at the lab will scan your body (much like with early photography, you’ll need to be able to hold a certain pose for 15 minutes) and print out an impressively realistic 3D photo that captures not only your features, but also the basic textures of your clothing and hair. (via Julie Starr)
- Feynman Flowers — crowdsourcing analysis of STM imagery for nanoscale physics research. (via OKFN)
- Mobile Trends — Android on exponential growth vs iOS’s linear growth, and many more data-driven observations. Apple has a mobile product at every $50 price point between $0 and $850.

3D Printed Drones, When Pacemakers Attack, N-Gram Updated, and Deanonymizing Datasets
- Home-made 3D-Printed Drones — if only they used computer-vision to sequence DNA, they’d be the perfect storm of O’Reilly memes :-)
- Hacking Pacemakers For Death — IOActive 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.
- 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.
- Deanonymizing Mobility Traces: Using Social Networks as a Side-Channel — a 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. (via Network World)
Drone Conflict, 3D Scanning Booths, Bitcoin Consensus, and Moar Coders
- 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.
- 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)
- 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)
- 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.
- 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.
- Legacy Media Demanding Surveillance In ISPs — music 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 …
- 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.
Programming Patterns, Limits of Observation, Surviving Transparency, 3D Printing Sounds
- 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.
- Milton Friedman’s Thermostat — Everybody 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)
- 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.

- 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.
