Power of Small Groups (Matt Webb) — Matt’s joined a small Slack community of like-minded friends. There’s a space where articles written or edited by members automatically show up. I like that. I caught myself thinking: it’d be nice to have Last.FM here, too, and Dopplr. Nothing that requires much effort. Let’s also pull in Instagram. Automatic stuff so I can see what people are doing, and people can see what I’m doing. Just for this group. Back to those original intentions. Ambient awareness, togetherness. cf Clay Shirky’s situated software. Everything useful from 2004 will be rebuilt once the fetish for scale passes.
Asymmetric Misperceptions (PDF) — research into the systematic mismatch between how politicians think their constituents feel on issues, and how the constituents actually feel. Our findings underscore doubts that policymakers perceive opinion accurately: politicians maintain systematic misperceptions about constituents’ views, typically erring by over 10 percentage points, and entire groups of politicians maintain even more severe collective misperceptions. A second, post-election survey finds the electoral process fails to ameliorate these misperceptions.
The Mystery Machine (A Paper a Day) — rundown of Facebook’s Mystery Machine, which can measure end-to-end performance from the initiation of a page load in a Web browser, all the way through the server-side infrastructure, and back out to the point where the page has finished rendering. Doing this requires a causal model of the relationships between components (happens-before). How do you get that? And especially, how do you get that if you can’t assume a uniform environment for instrumentation?
Smartphone Energy Consumption (Pete Warden) — I love new ways of looking at familiar things. Looking at code and features through the lens of power consumption is another such lens. (I remember Craig from Craigslist talking at OSCON about using power as the denominator in your data center, changing how I saw the Web). The article is full of surprising numbers and fascinating factoids. Active cell radio might use 800 mW. Bluetooth might use 100 mW. Accelerometer is 21 mW. Gyroscope is 130 mW. Microphone is 101 mW. GPS is 176 mW. Using the camera in ‘viewfinder’ mode, focusing and looking at a picture preview, might use 1,000 mW. Actually recording video might take another 200 to 1,000 mW on top of that.
Announcing Otto — new Hashicorp tool that automatically builds development environments without any configuration; it can detect your project type and has built-in knowledge of industry-standard tools to setup a development environment that is ready to go. When you’re ready to deploy, Otto builds and manages an infrastructure, sets up servers, builds, and deploys the application.
Homebrew Bioweapons Not Imminent Threat — you need a safe facility, lab instruments, base strain, design and execution skills, and testing. None of these are easy until the Amazon-Google cloud wars finally cause them to move into “bioweapons as a service.”
gitrob — a command line tool that can help organizations and security professionals find such sensitive information. The tool will iterate over all public organization and member repositories and match filenames against a range of patterns for files, that typically contain sensitive or dangerous information.
How Much is a Leader’s Integrity Worth? — Kiel found that high-integrity CEOs had a multi-year return of 9.4%, while low-integrity CEOs had a yield of just 1.9%. What’s more, employee engagement was 26% higher in organizations led by high-integrity CEOs. (via Neelan Choksi)
Police Program Aims to Pinpoint Those Most Likely to Commit Crimes (NYT) — John S. Hollywood, a senior operations researcher at the RAND Corporation, said that in the limited number of studies undertaken to measure the efficacy of predictive policing, the improvement in forecasting crimes had been only 5% or 10% better than regular policing methods.
Apple’s Assault on Advertising and Google (Calacanis) — Google wants to be proud of their legacy, and tricking people into clicking ads and selling our profiles to advertisers is an awesome business – but a horrible legacy for Larry and Sergey. Read beside the Bloomberg piece on click fraud and the future isn’t too rosy for advertising. If the ad bubble bursts, how much of the Web will it take with it?
$9 Computer Hardware (Makezine) — open hardware project, with open source software. The board’s spec is a 1GHz R8 ARM processor with 512MB of RAM, 4GB of NAND storage, and Wi-Fi and Bluetooth built in.
Data Analytics in Sports — O’Reilly research report (free). When it comes to processing stats, competing companies Opta and ProZone use a combination of recording technology and human analysts who tag “events” within the game (much like Vantage Sports). Opta calculates that it tags between 1,600 and 2,000 events per football game — all delivered live.
Ant Algorithms for Discrete Optimization (Adrian Colyer) — Stigmergy is the generic term for the stimulation of workers by the performance they have achieved – for example, termite nest-building works in a similar way. Stigmergy is a form of indirect communication “mediated by physical modifications of environmental states which are only locally accessible to the communicating agents.
Deep Belief Networks at the Heart of NASA Image Classification — The two new labeled satellite data sets were put to the test with a modified deep-belief-networks-driven approach, ultimately. The results show classification accuracy of 97.95%, which performed better than the unmodified pure deep belief networks, convolutional neural networks, and stacked de-noising auto-encoders by around 11%.
China Extracting Pledge of Compliance from US Firms (NY Times) — The letter also asks the American companies to ensure their products are “secure and controllable,” a catchphrase that industry groups said could be used to force companies to build so-called back doors — which allow third-party access to systems — provide encryption keys or even hand over source code.
Toyota’s Robot Car Plans (IEEE Spectrum) — Toyota hired the former head of DARPA’s Robotics Challenge. Pratt explained that a U.S. $50 million R&D collaboration with MIT and Stanford is just the beginning of a large and ambitious program whose goal is developing intelligent vehicles that can make roads safer and robot helpers that can improve people’s lives at home.
How Will Real-Time Tracking Change the NFL? (New Yorker) — At the moment, the NFL is being tightfisted with the data. Commentators will have access during games, as will the betting and analytics firm Sportradar. Users of the league’s Xbox One app, which provides an interactive way of browsing video clips, fantasy-football statistics, and other metrics, will be able to explore a feature called Next Gen Replay, which allows them to track each player’s speed and trajectory, combining moving lines on a virtual field with live footage from the real one. But, for now, coaches are shut out; once a player exits the locker room on game day, the dynamic point cloud that is generated by his movement through space is a corporately owned data set, as outlined in the league’s 2011 collective-bargaining agreement. Which should tell you all you need to know about the NFL’s role in promoting sporting excellence.
Uber Would Like to Buy Your Robotics Department (NY Times) — ‘‘If you’re well versed in the area of robotics right now and you’re not working on self-driving cars, you’re either an idiot or you have more of a passion for something else,’’ says Jerry Pratt, head of a robotics team in Pensacola that worked on a humanoid robot that beat Carnegie Mellon’s CHIMP in this year’s contest. ‘‘It’s a multibillion- if not trillion-dollar industry.’’
What the Heck is Angela Ahrendts Doing at Apple? (Fortune) — Apple has always intended for each of them to be a community center; now Cook and Ahrendts want them to be the community center. That means expanding from serving existing and potential customers to, say, creating opportunities for underserved minorities and women. “In my mind,” Ahrendts says, store leaders “are the mayors of their community.”
