- Measuring Heart Rate with a Smartphone Camera — not yet realtime, but promising sensor development.
- iBeacons — low-power, short-distance location monitoring beacons. Any iOS device that supports Bluetooth Low Energy can become an iBeacon, and can detect other iBeacons when they are nearby. Apps can be notified when iBeacons move in and out of range of the device, and can monitor the proximity of iBeacons as their proximity changes over time.
- Analysis: The Quantified Self (BBC) — radio show on QS. Good introduction for the novice.
- Tinke — heart rate, blood oxygen, respiration rate, and heart rate variability in a single small sensor that plugs into your iOS device.

Toxic Behaviour, Encryption Deception, Foursquare Strategy, and Problem-First Learning
- Toxic Behaviour — only 5% of toxic behavior comes from toxic people; 77% of it comes from people who are usually good.
- More Encryption Is Not The Solution (Poul-Henning Kamp) — To an intelligence agency, a well-thought-out weakness can easily be worth a cover identity and five years of salary to a top-notch programmer. Anybody who puts in five good years on an open source project can get away with inserting a patch that “on further inspection might not be optimal.”
- On Location With Foursquare (Anil Dash) — Foursquare switched from primarily being concerned with the game-based rewards around engagement and the recording of people’s whereabouts to a broader mission that builds on that base to be about location as a core capability of the Internet.
- The Flipped Flipped Classroom — the “exploration first” model is a better way to learn. You cannot have the answers before you think of the questions. (via Karl Fisch)
History as Science, Indoor Location, Nightscape Photography, and Finding the Impossible
- Cliodynamics: History as Science — a systematic application of the scientific method to history: verbal theories should be translated into mathematical models, precise predictions derived, and then rigorously tested on empirical material. In short, history needs to become an analytical, predictive science.
- Cricket — indoor location system from MIT. In a nutshell, Cricket uses a combination of RF and ultrasound technologies to provide location information to attached host devices. Wall- and ceiling-mounted beacons placed through a building publish information on an RF channel. [...] The listener runs algorithms that correlate RF and ultrasound samples (the latter are simple pulses with no data encoded on them) and to pick the best correlation. Even in the presence of several competing beacon transmissions, Cricket achieves good precision and accuracy quickly.
- The World at Night — an international effort to present stunning nightscape photos and time-lapse videos of the world’s landmarks against celestial attractions.
- Paul Steinhardt on Impossible Crystals (YouTube) — quasi-crystals with five-fold symmetry previously believed impossible. And then he found one, and led an expedition in 2011 to Chukotka in Far Eastern Russia to find new information about its origin and search for more samples. As you do when you’re the Albert Einstein Professor of Science at Princeton, a job title that comes with no pressure at all to bring home the impossible.
Location Data, Online Science, Mythbusting for Education, and Cheap Music For All
- Reading Runes in Animal Movement (YouTube) — accessible TEDxRiverTawe 2013 talk by Professor Rory Wilson, on his work tracking movements of animals in time and space. The value comes from high-resolution time series data: many samples/second, very granular.
- Best Science Writing Online 2012 (Amazon) — edited collection of the best blog posts on science from 2012. Some very good science writing happening online.
- Designing Effective Multimedia for Physics Education (PDF) — Derek Muller’s PhD thesis, summarised as “mythbusting beats lectures, hands down”. See also his TED@Sydney talk.
- Melomics — royalty-free computer-generated music, all genres, for sale (genius business model). Academic spinoff from Dr. Francisco J. Vico’s work at UMA in Spain.
This is the beginning of a great rewiring of every aspect of business processes and interactions.
Google Maps alternatives, inside Dart, and the upside of offline.
This week on O'Reilly: StreetEasy's Sebastian Delmont explained why his team left Google Maps behind, we looked at the ins and outs of the Dart programming platform, and Jim Stogdill considered the alternatives to always-on living.
Sebastian Delmont on alternatives to Google Maps.
Google's decision to start charging for its Maps API is leading some companies to mull other options. In this interview, StreetEasy's Sebastian Delmont explains why and how his team made a change.
The nuances of location language, game devs find funding through Kickstarter, and the state of ebook pricing.
This week on O'Reilly: Computational linguist Robert Munro explained why location language is far more complex than many realize, we looked at how Kickstarter's crowdfunding is helping game developers, and Joe Wikert explored the major trends shaping ebook prices.
Visualizations, RFID installs and a Mini Maker Faire will be featured at Where 2012.
The 2012 Where Conference is looking for makers, hackers, developers and do-it-yourselfers who are working in the geolocation and mapping spaces.
