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.
Sparkey — Spotify’s open-sourced simple constant key/value storage library, for read-heavy systems with infrequent large bulk inserts.
The Truth of Fact, The Truth of Feeling (Ted Chiang) — story about what happens when lifelogs become searchable. Now with Remem, finding the exact moment has become easy, and lifelogs that previously lay all but ignored are now being scrutinized as if they were crime scenes, thickly strewn with evidence for use in domestic squabbles. (via BoingBoing)
InterTwinkles — open source platform built from the ground up to help small democratic groups to do process online. It provides structure to improve the efficiency of specific communication tasks like brainstorming and proposals. (via Willow Bl00)
Modeling Users’ Activity on Twitter Networks: Validation of Dunbar’s Number (PLoSone) — In this paper we analyze a dataset of Twitter conversations collected across six months involving 1.7 million individuals and test the theoretical cognitive limit on the number of stable social relationships known as Dunbar’s number. We find that the data are in agreement with Dunbar’s result; users can entertain a maximum of 100–200 stable relationships. Thus, the ‘economy of attention’ is limited in the online world by cognitive and biological constraints as predicted by Dunbar’s theory. We propose a simple model for users’ behavior that includes finite priority queuing and time resources that reproduces the observed social behavior.
Mary Meeker’s Internet Trends (Slideshare) — check out slide 24, ~2x month-on-month growth for MyFitnessPal’s number of API calls, which Meeker users as a proxy for “fitness data on mobile + wearable devices”.
What I Learned as an Oompa Loompa (Elaine Wherry) — working in a chocolate factory, learning the differences and overlaps between a web startup and an more traditional physical goods business. It’s so much easier to build a sustainable organization around a simple revenue model. There are no tensions between ad partners, distribution sites, engineering, and sales teams. There are fewer points of failure. Instead, everyone is aligned towards a simple goal: make something people want.
Augmented Reality Futures (Quartz) — wrap-up of tech in the works and coming. Instruction is the bit that interests me, scaffolding our lives: While it isn’t on the market yet, Inglobe Technologies just previewed an augmented reality app that tracks and virtually labels the components of a car engine in real time. That would make popping the hood of your car on the side of the road much less scary. The app claims to simplify tasks like checking oil and topping up coolant fluid, even for novice mechanics.
Computer Software Archive (Jason Scott) — The Internet Archive is the largest collection of historical software online in the world. Find me someone bigger. Through these terabytes (!) of software, the whole of the software landscape of the last 50 years is settling in. (And documentation and magazines and …). Wow.
Hacking Secret Ciphers with Python — teaches complete beginners how to program in the Python programming language. The book features the source code to several ciphers and hacking programs for these ciphers. The programs include the Caesar cipher, transposition cipher, simple substitution cipher, multiplicative & affine ciphers, Vigenere cipher, and hacking programs for each of these ciphers. The final chapters cover the modern RSA cipher and public key cryptography.
Bend Not Break — she had an amazing life but this caught my eye in the Make review: In China, she told me, making and craftsmanship are highly revered, and under Mao, factory jobs were prized. Her experience working in Mao’s factories planted a seed in her mind that sprouted when she sought to create her own company. Rather than launch another internet-based business as was the rage at the time, she wanted to connect software to the physical world. (via Makezine)
DIY Weapons of the Syrian Rebels (The Atlantic) — if WWII France had had X-Box controllers, they’d have been releasing remote controlled homebrew deathmobiles too.
Community Memory (Wired) — In the early 1970s, Efrem Lipkin, Mark Szpakowski and Lee Felsenstein set up a series of these terminals around San Francisco and Berkeley, providing access to an electronic bulletin board housed by a XDS-940 mainframe computer. This started out as a social experiment to see if people would be willing to share via computer — a kind of “information flea market,” a “communication system which allows people to make contact with each other on the basis of mutually expressed interest,” according to a brochure from the time. What evolved was a proto-Facebook-Twitter-Yelp-Craigslist-esque database filled with searchable roommate-wanted and for-sale items ads, restaurant recommendations, and, well, status updates, complete with graphics and social commentary. But did it have retargeted ads, promoted tweets, and opt-in messages from partners? I THOUGHT NOT. (via BoingBoing)
Latency Numbers Every Programmer Should Know (EECS Berkeley) — exactly that. I was always impressed by Artur Bergman’s familiarity with the speed of packets across switches, RAM cache misses, and HDD mean seek times. Now you can be that impressive person.
Feds Requiring Black Boxes in All Vehicles (Wired) — [Q]uestions remain about the black boxes and data. Among them, how long should a black box retain event data, who owns the data, can a motorist turn off the black box and can the authorities get the data without a warrant. This is starting as regulatory compliance, but should be seized as an opportunity to have a quantified self.
Average Age of StackExchange Users by Tag (Brian Bondy) — no tag is associated with people who have a mean age over 30. Did I miss the plague that wiped out all the programmers over the age of 30? Or does age bring with it supreme knowledge so that old people like me never have to use StackExchange? Yes, that must be it. *cough*
Helping Drones Play Nice With Other Aviation — The U.S. airspace is quickly being filled with simultaneously flying drones. To such an extent, unmanned aircraft could soon become a nightmare for the ATC controllers. The ADS-B will improve Predator B’s crew situational awareness making the drone capable to operate more freely and safely in domestic and international airspace in accordance with civilian air traffic and airspace rules and regulations.
Reclaiming NZ’s Digitised Heritage — Out of a sample of 100 books: 50% of NZ Heritage Books (published before 1890) have been digitised; 90% of digitised texts are fully accessible; 98% of accessible texts are downloadable; Despite all works being in the public domain, only one did not have any licencing restrictions applied to its use. Most groups who digitise then go on to put restrictions around their use. [T]here are also many instances where arbitrary restrictions are being applied to the detriment of the public good.

Kenya’s Treasury to tax M-Pesa — 10% tax on mobile money-transfer systems. M-Pesa is the largest mobile money transfer service provider in Kenya, with more than 14 million subscribers. […] It is estimated that M-Pesa reports some 2 million transactions per day. […] the value of money transferred through mobile platforms jumped by 41 per cent in the first six months of 2012. Neer mind fighting you, you know you’re winning when they tax you! (via Evgeny Mozorov)
Digital Divide and Fibre Rollout — As the group of non-users gets smaller, they are likely to become more seriously disadvantaged. The NBN – and high-speed broadband more generally – will drive a wave of new applications across most areas of life, transforming Australia’s service economy in fundamental ways. Those who are not connected in 2015 may be fewer, but they will be missing out on far more – in education, health, government, commerce, communication and entertainment. The costs will also fall on service providers forced to keep supplying expensive physical and face-to-face services to this declining number of people. This will be particularly significant in remote communities, where health consultations and evacuations by flying doctors, nurses and allied health professionals could potentially be reduced through e-health diagnostics, and where Centrelink still regularly sends teams out to communities. As gov2 expands and services move online, connectivity disadvantages are compounded. (via Ellen Strickland)
Smart Body Smart World (Forrester) — take note of these two consequences of Internet of Things and Quantified Self: Verticals fuse: “Health and wellness” is not its own silo, but is connected to our finances, our shopping habits, our relationships. As bodies get connected, everyone is in the body business. Retail disperses: All retailers become computing retailers, and computing-specific retailers like Best Buy go the way of Blockbuster. You wouldn’t buy a smart toothbrush at a specialty CE store; you’d be more likely to buy it in the channel that solves the rest of your hygiene needs. (via Internet of Things)
Bank of England Complains About AR Bank Notes — After downloading the free Blippar app on iPhone or Android, customers were able to ‘blipp’ any ten-pound note in circulation by opening the app and holding their phone over the note. An animated Queen, and other members of the Royal Family, then appeared on the screen and voiced opinions on the latest football matters.
Quantified Mind — battery of cognitive tests, so you can track performance over time and measure the effect of interventions (coffee, diet, exercise, whatever). (via Sara Winge)
Jellyfish Made From Rat Cells (Nature) — an artificial jellyfish using silicone and muscle cells from a rat’s heart. The synthetic creature, dubbed a medusoid, looks like a flower with eight petals. When placed in an electric field, it pulses and swims exactly like its living counterpart. Very cool, but the bit that caught my eye was: the team built the medusoid as a way of understanding the “fundamental laws of muscular pumps”. It is an engineer’s approach to basic science: prove that you have identified the right principles by building something with them.
