1. Wearable Power Assist Device Goes on Sale in Japan (WSJ, Paywall) — The Muscle Suit, which weighs 5.5 kilograms (12 pounds), can be worn knapsack-style and uses a mouthpiece as its control. Unlike other similar suits that rely on motors, it uses specially designed rubber tubes and compressed air as the source of its power. The Muscle Suit can help users pick up everyday loads with about a third of the usual effort. […] will sell for about ¥600,000 ($5,190), and is also available for rent at about ¥30,000 to ¥50,000 per month. Prof. Kobayashi said he expected the venture would ship 5,000 of them in 2015. (via Robot Economics) 2. Debunking Handbook — techniques for helping people to change their beliefs (hint: showing them data rarely does it). (via Tom Stafford) 3. Building a Complete Tweet Index (Twitter) — engineering behind the massive searchable Tweet collection: indexes roughly half a trillion documents and serves queries with an average latency of under 100ms. 4. History of the Poop Emoji (Fast Company) — In Japanese, emoji are more like characters than random animated emoticons.

The Infinite Hows (John Allspaw) — when finding ways to improve systems to prevent errors, the process of diagnosis should be focused on the systems and less on the people. (aka “human error” is the result of a preceding systems error.) (aka “design for failure.”) 2. Amazon Lambda — triggers in the cloud. 3. Enchanted Objects (PNG) — organizing the Internet of Thing by human desires. (via Designing the Enchanted Future) 4. Barbie Remixed (PDF) — brilliant remix of a book that missed the mark into one that hits the bullseye. Comment ## Four short links: 10 November 2014 ### Metascience, Bio Fab, Real-time Emoji, and Phone Library 1. Metascience Could Rescue the Replication Crisis (Nature) — Metascience, the science of science, uses rigorous methods to examine how scientific practices influence the validity of scientific conclusions. (via Ed Yong) 2. OpenTrons (Kickstarter) — 3d-printer style frame for micropipetting, magnetic micro-bead washes, and photography. Open source and kickstarterated. (via Evil Mad Scientist) 3. Emoji Tracker — real-time emoji use across Twitter. (via Chris Aniszczyk) 4. libphonenumber — open source Google’s common Java, C++ and Javascript library for parsing, formatting, storing and validating international phone numbers. The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich). Comment ## Four short links: 30 October 2014 ### Security and Privacy, ISP Measurement, Github for Education, and Mobile Numbers 1. A Critique of the Balancing Metaphor in Privacy and SecurityThe arguments presented by this paper are built on two underlying assertions. The first is that the assessment of surveillance measures often entails a judgement of whether any loss in privacy is legitimised by a justifiable increase in security. However, one fundamental difference between privacy and security is that privacy has two attainable end-states (absolute privacy through to the absolute absence of privacy), whereas security has only one attainable end-state (while the absolute absence of security is attainable, absolute security is a desired yet unobtainable goal). The second assertion, which builds upon the first, holds that because absolute security is desirable, new security interventions will continuously be developed, each potentially trading a small measure of privacy for a small rise in security. When assessed individually each intervention may constitute a justifiable trade-off. However, when combined together, these interventions will ultimately reduce privacy to zero. (via Alistair Croll) 2. ISP Interconnection and its Impact on Consumer Internet Performance (Measurement Lab) — In researching our report, we found clear evidence that interconnection between major U.S. access ISPs (AT&T, Comcast, CenturyLink, Time Warner Cable, and Verizon) and transit ISPs Cogent, Level 3, and potentially XO was correlated directly with degraded consumer performance throughout 2013 and into 2014 (in some cases, ongoing as of publication). Degraded performance was most pronounced during peak use hours, which points to insufficient capacity and congestion as a causal factor. Further, by noting patterns of performance degradation for access/transit ISP pairs that were synchronized across locations, we were able to conclude that in many cases degradation was not the result of major infrastructure failures at any specific point in a network, but rather connected with the business relationships between ISPs. 3. The Emergence of Github as Collaborative Platform for Education (PDF) — We argue that GitHub can support much of what traditional learning systems do, as well as go beyond them by supporting collaborative activities. 4. Mobile is Eating the World (A16Z) — mobile becoming truly ubiquitous, bringing opportunities to use the construct “X is eating Y.” Comment ## Four short links: 27 October 2014 ### Maker Education, Content Moderators, New Microscopy, and Hardware Emulation in LaTeX 1. Progressive Education and the Maker Movement (PDF) — Gary Stager paper on how constructivist education (learning happens best via experience) and the Maker movement need each other. (via Paula Hogg) 2. Content Moderation (Wired) — “content moderators” are the people paid to weed out beheadings, pornography, etc. from photo and video sites. By at least one estimate, the number of content moderators scrubbing the world’s social media sites, mobile apps, and cloud storage services runs to “well over 100,000”—that is, about twice the total head count of Google and nearly 14 times that of Facebook. 3. Amazing New Microscope (National Geographic) — Lattice light sheet microscopy takes amazing movies, completely with Matrix-can freeze-and-rotate, from the recipient of this year’s Nobel Prize for Chemistry. 4. avremu — an AVR (the chip inside the Arduino) emulator written in LaTeX. Yes, LaTeX. Comment ## Four short links: 29 September 2014 ### Feedback Surprises, Ownership Changes, Teaching Lessons, and 3D Retail 1. How Community Feedback Shapes Behaviour (PDF) — Not only do authors of negatively-evaluated content contribute more, but also their future posts are of lower quality, and are perceived by the community as such. Moreover, these authors are more likely to subsequently evaluate their fellow users negatively, percolating these effects through the community. In contrast, positive feedback does not carry similar effects, and neither encourages rewarded authors to write more, nor improves the quality of their posts. Interestingly, the authors that receive no feedback are most likely to leave a community. Furthermore, a structural analysis of the voter network reveals that evaluations polarize the community the most when positive and negative votes are equally split. 2. When Everything Works Like Your Cell Phone (The Atlantic) — our relationship to ownership is about to undergo a wild transformation. 3. Teaching Me Softly — article of anecdotes drawing parallels between case studies in machine learning and things we know about human learning. 4. SuperAwesome Me (3D Print) — Walmart to install 3d scanning booths and 3d printers so you can put your own head on a Hasbro action figure. Hasbro have the religion: they also paired with Shapeways for superfanart.com. (via John Battelle) Comment ## Four short links: 26 September 2014 ### Good Communities, AI Games, Design Process, and Web Server Library 1. 15 Lessons from 15 Years of Blogging (Anil Dash) — If your comments are full of assholes, it’s your fault. Good communities don’t just happen by accident. 2. Replicating DeepMind — open source attempt to build deep learning network that can play Atari games. (via RoboHub) 3. ToyTalk — fantastic iterative design process for the product (see the heading “A Bit of Trickery”) 4. h2oan optimized HTTP server implementation that can be used either as a standalone server or a library. Comment ## Four short links: 9 September 2014 ### Go Text, Science Consensus, Broadcast Fallacy, and In-Browser Swift 1. bleveA modern text indexing library for go. 2. Scientific Consensus Has A Bad Reputation—And Doesn’t Deserve It (Ars Technica) — a lovely explanation of how informal consensus works in science. NB for anyone building social software which attempts to formalise and automate consensus. 3. TiVo Mega — 24TB of RAID storage, six tuners for capturing broadcasts. Which is rather like building the International Space Station and then hitching it to six horses for launch. Who at this point would make a$5k bet that everything you want to see on a TV will be broadcast by a cable company?
4. runswift — an in-browser client for compiling and running basic Swift functionality.
