- Pete Warden on Sensors — We’re all carrying little networked laboratories in our pockets. You see a photo. I see millions of light-sensor readings at an exact coordinate on the earth’s surface with a time resolution down to the millisecond. The future is combining all these signals into new ways of understanding the world, like this real-time stream of atmospheric measurements.
- Quine Relay — This is a Ruby program that generates Scala program that generates Scheme program that generates …(through 50 languages)… REXX program that generates the original Ruby code again.
- Cello — a GNU99 C library which brings higher level programming to C. Interfaces allow for structured design, Duck Typing allows for generic functions, Exceptions control error handling, Constructors/Destructors aid memory management, Syntactic Sugar increases readability.
- The Meeting (John Birmingham) — satirising the Wall Street Journal’s meeting checklist advice.

Street View Tiles Hacks, Policy Simulation, Map Tile Toolbox, and Connected Sensor Device HowTo
- HyperLapse — this won the Internet for April. Everyone else can go home. Check out this unbelievable video and source is available.
- Housing Simulator — NZ’s largest city is consulting on its growth plan, and includes a simulator so you can decide where the growth to house the hundreds of thousands of predicted residents will come from. Reminds me of NPR’s Budget Hero. Notice that none of the levers control immigration or city taxes to make different cities attractive or unattractive. Growth is a given and you’re left trying to figure out which green fields to pave.
- Converting To and From Google Map Tile Coordinates in PostGIS (Pete Warden) — Google Maps’ system of power-of-two tiles has become a defacto standard, widely used by all sorts of web mapping software. I’ve found it handy to use as a caching scheme for our data, but the PostGIS calls to use it were getting pretty messy, so I wrapped them up in a few functions. Code on github.
- So You Want to Build A Connected Sensor Device? (Google Doc) — The purpose of this document is to provide an overview of infrastructure, options, and tradeoffs for the parts of the data ecosystem that deal with generating, storing, transmitting, and sharing data. In addition to providing an overview, the goal is to learn what the pain points are, so we can address them. This is a collaborative document drafted for the purpose of discussion and contribution at Sensored Meetup #10. (via Rachel Kalmar)
Why general purpose computing will diffuse into our environment.
- 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.
Open Publishing, Theatre Sensing, Reddit First, and Math Podcasts
- Open Monograph Press — an open source software platform for managing the editorial workflow required to see monographs, edited volumes and, scholarly editions through internal and external review, editing, cataloguing, production, and publication. OMP will operate, as well, as a press website with catalog, distribution, and sales capacities. (via OKFN)
- Sensing Activity in Royal Shakespeare Theatre (NLTK) — sensing activity in the theatre, for graphing. Raw data available. (via Infovore)
- Why Journalists Love Reddit (GigaOM) — “Stories appear on Reddit, then half a day later they’re on Buzzfeed and Gawker, then they’re on the Washington Post, The Guardian and the New York Times. It’s a pretty established pattern.”
- Relatively Prime: The Toolbox — Kickstarted podcasts on mathematics. (via BoingBoing)
Personalized Education, Programming Living Data, The Invisible Economy, and State vs Internet
- Personalization (Chris Lehmann) — We should be careful about how we use that term, and we should be very skeptical of how well computerized programs can really personalize for kids. Most of what I see – especially from curriculum and assessment vendors – involves personalization of pace while still maintaining standardization of content. This.
- Unveiling Quadrigram (Near Future Laboratory) — a Visual Programming Environment to gather, shape and share living data. By living data we mean data that are constantly changing and accumulating. They can come from social network, sensor feeds, human activity, surveys, or any kind of operation that produce digital information.
- Tim O’Reilly at MIT Media Lab (Ethan Zuckerman) — a great recap of a Tim talk. There’s an interesting discussion of the unmeasured value created by peer-to-peer activities (such as those made dead simple by the Internet), which is one of the new areas we’re digging into here at O’Reilly.
- The State vs the Internet (David Eaves) — we’ve all seen many ways in which the Internet is undermining the power of nation states. A session at Foo asked how it was going to end (which would give way first?), and this is an excellent recap. It could be that the corporation is actually the entity best positioned to adapt to the internet age. Small enough to leverage networks, big enough to generate a community that is actually loyal and engaged.
Learning Adventure, Python Data Analysis, Lanyrd Technology, and New Sensor
- Hippocampus Text Adventure — written as an exercise in learning Python, you explore the hippocampus. It’s simple, but I like the idea of educational text adventures. (Well, educational in that you learn about more than the axe-throwing behaviour of the cave-dwelling dwarf)
- Pandas — BSD-licensed Python data analysis library.
- Building Lanyrd — Simon Willison’s talk (with slides) about the technology under Lanyrd and the challenges in building with and deploying it.
- Electronic Skin Monitors Heart, Brain, and Muscles (Discover Magazine blogs) — this is freaking awesome proof-of-concept. Interview with the creator of a skin-mounted sensor, attached like a sticker, is flexible, inductively powered, and much more. This represents a major step forward in possibilities for personal data-gathering. (via Courtney Johnston)
Sensor Trojan, node.js IDE, Quantified Conference, and P2P Streaming
- Proof-of-Concept Android Trojan Captures Spoken Credit-Card Numbers — Soundminer sits in the background and waits for a call to be placed [...] the application listens out for the user entering credit card information or a PIN and silently records the information, performing the necessary analysis to turn it from a sound recording into a number. Very clever use of sensors for evil! (via Slashdot)
- Cloud9 IDE — open source IDE for node.js. I’m using it as I learn node.js, and it’s sweet as, bro.
- The Quantified Self Conference — May 28-29 in Mountain View. (via Pete Warden)
- Bram Cohen Demos P2P Streaming — the creator of BitTorrent is winding up to release a streaming protocol that is also P2P. (via Hacker News)
Android, Cellphone Photos, Long-Exposure iPhone Apps, and Open Street Map
- What Android Is (Tim Bray) — a good explanation of the different bits and their relationship.
- Cell Phone Photo Helped in Oil Spill (LA Times) — a lone scientist working from a cell phone photo who saved the day by convincing the government that a cap it considered removing was actually working as designed. (via BoingBoing)
- Penki — iPhone app that lets you paint 3D messages which are revealed in long-exposure photographs. (via Aaron Straup Cope on Delicious)
- I’m Working at Microsoft and We’re Donating Imagery to OpenStreetMap! (Steve Coast) — MSFT hired the creator of OSM and he says Microsoft is donating access to its global orthorectified aerial imagery to help OpenStreetMappers make the map even better than it already is.
