Overview of the Civilian Drone Market (DIY Drones) — Six categories: toy quadcopters; FPV/racing; consumer camera drones; prosumer camera drones; consumers, industrial, agricultural, NGO and Research drones; winged and VTOL drones.
Bottom Up Computer Science — A free, online book designed to teach computer science from the bottom end up. Topics covered include binary and binary logic, operating systems internals, toolchain fundamentals, and system library fundamentals.
The Economics of Drone Delivery — The analysis is still mostly speculative. Keeney imagines that 6,000 operators who earn $50,000 per year will operate 30,000 to 40,000 drones. Each drone will make 30 deliveries per day. Her analysis ignores depreciation and questions like: ‘How will drones avoid airplanes and deliver packages in Manhattan?’ And there’s another core issue: $12.92 is the price UPS charges to consumers, but its actual marginal cost of delivering one more package along a route they are delivering to already is probably closer to $2. When push comes to shove, will drones be able to compete? (via Chris Anderson)
7 Ways Your Data is Telling You It’s a Graph — Network, tree, taxonomy, ancestry, structure – if people are using those words to talk about an organizational chart or reporting structure, they’re telling you that data and the relationships between that data are important.
Six Degrees of Francis Bacon — recreates the British early modern social network to trace the personal relationships among figures like Bacon, Shakespeare, Isaac Newton, and many others. (via CMU)
Last Bus Startup Standing (TechCrunch) — Vahabzadeh stressed that a key point of Chariot’s survival has been that the company has been above-board with the law from day one. “They haven’t cowboy-ed it,” said San Francisco supervisor Scott Wiener, a mass transit advocate who recently pushed for a master subway plan for the city. “They’ve been good about taking feedback and making sure they’re complying with the law. I’m a fan and think that private transportation options and rideshares have a significant role to play in making us a transit-first city.”
Mobile App Developers are Suffering — the top 20 app publishers, representing less than 0.005% of all apps, earn 60% of all app store revenue. The article posits causes of the particularly extreme power law.
How Big is the Gig Economy? (Medium) — this is one example in which the Labor Department and Bureau of Labor Statistics really have shirked their responsibility to try and assess the size and growth of this dynamic shift to our economy.
The Twelve Networking Truths — RFC1925 is channeling the epigram-leaking protagonist of Robert Heinlein’s Time Enough for Love. It is easier to move a problem around (for example, by moving the problem to a different part of the overall network architecture) than it is to solve it. This is true for most areas of life: generally easier to make it someone else’s problem than to solve it.
The Decay of Twitter (The Atlantic) — In other words, on Twitter, people say things that they think of as ephemeral and chatty. Their utterances are then treated as unequivocal political statements by people outside the conversation. Because there’s a kind of sensationalistic value in interpreting someone’s chattiness in partisan terms, tweets “are taken up as magnum opi to be leapt upon and eviscerated, not only by ideological opponents or threatened employers but by in-network peers.”
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.
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.
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.
Microservices Without the Servers (Amazon) — By “serverless,” we mean no explicit infrastructure required, as in: no servers, no deployments onto servers, no installed software of any kind. We’ll use only managed cloud services and a laptop. The diagram below illustrates the high-level components and their connections: a Lambda function as the compute (“backend”) and a mobile app that connects directly to it, plus Amazon API Gateway to provide an HTTP endpoint for a static Amazon S3-hosted website.
Privacy vs Data Science — claims Apple is having trouble recruiting top-class machine learning talent because of the strict privacy-driven limits on data retention (Siri data: 6 months, Maps: 15 minutes). As a consequence, Apple’s smartphones attempt to crunch a great deal of user data locally rather than in the cloud.
NAS Backdoors — firmware in some Seagate NAS drives is very vulnerable. It’s unclear whether these are Seagate-added, or came with third-party bundled software. Coming soon to lightbulbs, doors, thermostats, and all your favorite inanimate objects. (via BetaNews)
