Note and Vote, Gaming Behaviour, Code Search, and Immutabilate All The Things

  1. Note and Vote (Google Ventures) — nifty meeting hack to surface ideas and identify popular candidates to a decision maker.
  2. Applying Psychology to Improve Online Behaviour — online game runs massive experiments (w/researchers to validate findings) to improve the behaviour of their players. Some of Riot’s experiments are causing the game to evolve. For example, one product is a restricted chat mode that limits the number of messages abusive players can type per match. It’s a temporary punishment that has led to a noticeable improvement in player behavior afterward —on average, individuals who went through a period of restricted chat saw 20 percent fewer abuse reports filed by other players. The restricted chat approach also proved 4 percent more effective at improving player behavior than the usual punishment method of temporarily banning toxic players. Even the smallest improvements in player behavior can make a huge difference in an online game that attracts 67 million players every month.
  3. Hound — open source code search tool from Etsy.
  4. Immutability Changes Everything (PDF) — This paper is simply an amuse-bouche on the repeated patterns of computing that leverage immutability.

Privacy Philosophy, Bitcoin Risks, Modelling Emotion, and Opinion Formation

  1. Google’s Philosopher — interesting take on privacy. Now that the mining and manipulation of personal information has spread to almost all aspects of life, for instance, one of the most common such questions is, “Who owns your data?” According to Floridi, it’s a misguided query. Your personal information, he argues, should be considered as much a part of you as, say, your left arm. “Anything done to your information,” he has written, “is done to you, not to your belongings.” Identity theft and invasions of privacy thus become more akin to kidnapping than stealing or trespassing. Informational privacy is “a fundamental and inalienable right,” he argues, one that can’t be overridden by concerns about national security, say, or public safety. “Any society (even a utopian one) in which no informational privacy is possible,” he has written, “is one in which no personal identity can be maintained.”
  2. S-1 for a Bitcoin Trust (SEC) — always interesting to read through the risks list to see what’s there and what’s not.
  3. Computationally Modelling Human Emotion (ACM) — our work seeks to create true synergies between computational and psychological approaches to understanding emotion. We are not satisfied simply to show our models “fit” human data but rather seek to show they are generative in the sense of producing new insights or novel predictions that can inform understanding. From this perspective, computational models are simply theories, albeit more concrete ones that afford a level of hypothesis generation and experimentation difficult to achieve through traditional theories.
  4. Opinion Formation Models on a Gradient (PLoSONE) — Many opinion formation models embedded in two-dimensional space have only one stable solution, namely complete consensus, in particular when they implement deterministic rules. In reality, however, deterministic social behavior and perfect agreement are rare – at least one small village of indomitable Gauls always holds out against the Romans. […] In this article we tackle the open question: can opinion dynamics, with or without a stochastic element, fundamentally alter percolation properties such as the clusters’ fractal dimensions or the cluster size distribution? We show that in many cases we retrieve the scaling laws of independent percolation. Moreover, we also give one example where a slight change of the dynamic rules leads to a radically different scaling behavior.

SQL against Text, Fake Social Networks, Hidden Biases, and Versioned Data

  1. textqlexecute SQL against structured text like CSV or TSV.
  2. Social Network Structure of Fake Friends — author bought 4,000 Twitter followers and studied their relationships.
  3. Hidden Biases in Big Datawith every big data set, we need to ask which people are excluded. Which places are less visible? What happens if you live in the shadow of big data sets? (via Quinn Norton)
  4. CoreObjecta version-controlled object database for Objective-C that supports powerful undo, semantic merging, and real-time collaborative editing.

Our Robot Future, Embeddable Pi, Behavioural Economics Not Solved Problem, and Imagine Processing Language

  1. Next Five Years for Robots — plausible summary of the near future progression, taken from Helen Greiner’s DEMOlabs talk.
  2. Raspberry Pi Compute Modulea Raspberry Pi shrunk down to fit on a SODIMM with onboard memory, whose connectors you can customise for your own needs. (via Makezine)
  3. Behavioural Economics and Public Policy (Financial Times) — interesting how A/B trials revealed that implementations of Cialdini’s social proof didn’t test as well as non-social-proof persuasive techniques. More useful than something that claims to be the right answer is knowing when you’re closer to the right answer. (via Mind Hacks)
  4. Halide Language — open source programming language designed to make it easier to write high-performance image processing code on modern machines. Its current front end is embedded in C++. Compiler targets include x86/SSE, ARM v7/NEON, CUDA, Native Client, and OpenCL.

BF Maker, Wikiseat, Decentralising Software, and Streaming Economics

  1. BF Skinner’s Baby Make Project (BoingBoing) — I got to read some of Skinner’s original writing on the Air-Crib recently and couple of things stuck out to me. First, it cracked me up. The article, published in 1959 in Cumulative Record, is written in the kind of extra-enthusiastic voice you’re used to hearing Makers use to describe particularly exciting DIY projects.
  2. Wikiseat — awesome Maker education project. (via Claire Amos)
  3. Redecentralize — project highlighting developers and software that disintermediates the ad-serving parasites preying on our human communication.
  4. The Internet Will Suck All Creative Content Out of the World (David Byrne) — persuasively argued that labels are making all the money from streaming services like Spotify, et al. Musicians are increasingly suspicious of the money and equity changing hands between these services and record labels – both money and equity has been exchanged based on content and assets that artists produced but seem to have no say over. Spotify gave $500m in advances to major labels in the US for the right to license their catalogues.

Notable Release, SVG Library, Modular Robot, and Factchecking Politicians Will Not Work

  1. Quick Reads of Notable New Zealanders — notable for two reasons: (a) CC-NC-BY licensed, and (b) gorgeous gorgeous web design. Not what one normally associates with Government web sites!
  2. svg.js — Javascript library for making and munging SVG images. (via Nelson Minar)
  3. Linkbot: Create with Robots (Kickstarter) — accessible and expandable modular robot. Loaded w/ absolute encoding, accelerometer, rechargeable lithium ion battery and ZigBee. (via IEEE Spectrum)
  4. The Promise and Peril of Real-Time Corrections to Political Misperceptions (PDF) — paper presenting results of an experiment comparing the effects of real-time corrections to corrections that are presented after a short distractor task. Although real-time corrections are modestly more effective than delayed corrections overall, closer inspection reveals that this is only true among individuals predisposed to reject the false claim. In contrast, individuals whose attitudes are supported by the inaccurate information distrust the source more when corrections are presented in real time, yielding beliefs comparable to those never exposed to a correction. We find no evidence of realtime corrections encouraging counterargument. Strategies for reducing these biases are discussed. So much for the Google Glass bullshit detector transforming politics.

Social Science, YAKVS, Open Source Mail, and Tesla Coil and Quadrocopter Fun

  1. The Effect of Group Attachment and Social Position on Prosocial Behavior (PLoSone) — notable, in my mind, for We conducted lab-in-the-field experiments involving 2,597 members of producer organizations in rural Uganda. cf the recently reported “rich are more selfish than poor” findings, which (like a lot of behavioural economics research) studies Berkeley undergrads who weren’t smart enough to figure out what was being studied.
  2. elephanta HTTP key/value store with full-text search and fast queries. Still a work in progress.
  3. geary (IndieGoGo) — a beautiful modern open-source email client. Found this roughly the same time as elasticinbox open source, reliable, distributed, scalable email store. Open source email action starting?
  4. The Faraday Copter (YouTube) — Tesla coil and quadrocopter madness. (via Jeff Jonas)

Patenting Preventing Placebos, Simulating Malaria, Pricing Experiments, and Mining Bitcoin

  1. Patent on Medical Trial Design to Reduce Placebo Effectdrug companies say these failures are happening not because their drugs are ineffective, but because placebos have recently become more effective in clinical trials. […] The whole idea that placebo effect is getting in the way of producing meaningful results is repugnant, I think, to anyone with scientific training. What’s even more repugnant, however, is that Fava’s group didn’t stop with a mere paper in Psychotherapy and Psychosomatics. They went on to apply for, and obtain, U.S. patents on SPCD. (via Ben Goldacre)
  2. OpenMalaria (Google Code) — an open source C++ program for simulating malaria epidemiology and the impacts on that epidemiology of interventions against malaria. It is based on microsimulations of Plasmodium falciparum malaria in humans, originally developed for simulating malaria vaccines. (via Victoria Stodden)
  3. Pricing Experiments You Might Not Know But Can Learn From — compendium of ideas and experiments for pricing.
  4. Retrominer — mining Bitcoins on a NES. I’m delighted by the conceit, and noticing that Bitcoin is now sufficiently part of the zeitgeist as to feature in playful hacks.

Psychology in a Nutshell, IRS Data, Fulltime Drone CEO, and SQL Injection

  1. The Psychology of Everything (YouTube) — illustrating some of the most fundamental elements of human nature through case studies about compassion, racism, and sex. (via Mind Hacks)
  2. Reports of Exempt Organizations (Public Resource) — This service provides bulk access to 6,461,326 filings of exempt organizations to the Internal Revenue Service. Each month, we process DVDs from the IRS for Private Foundations (Type PF), Exempt Organizations (Type EO), and filings by both of those kinds of organizations detailing unrelated business income (Type T). The IRS should be making this publicly available on the Internet, but instead it has fallen to Carl Malamud to make it happen. (via BoingBoing)
  3. Chris Anderson Leaves for Drone Co (Venturebeat) — Editor-in-chief of Wired leaves to run his UAV/robotics company 3D Robotics.
  4. pysqli (GitHub) — Python SQL injection framework; it provides dedicated bricks that can be used to build advanced exploits or easily extended/improved to fit the case.
