Nat has chaired the O'Reilly Open Source Convention and other O'Reilly conferences for over a decade. He ran the first web server in New Zealand, co-wrote the best-selling Perl Cookbook, and was one of the founding Radar bloggers. He lives in New Zealand and consults in the Asia-Pacific region.
Kalman Filter — an algorithm that uses a series of measurements observed over time, containing statistical noise and other inaccuracies, and produces estimates of unknown variables that tend to be more precise than those based on a single measurement alone.
Interview with Bruce Sterling — Singapore is like a science fictional society without the fiction. Dubai is like a science fictional society without the science. […] Robots just don’t want to live. They’re inventions, not creatures; they don’t have any appetites or enthusiasms. I don’t think they’d maintain themselves very long without our relentlessly pushing them uphill against their own lifeless entropy. They’re just not entities in the same sense that we are entities; they don’t have much skin in our game. They don’t care and they can’t be bothered. We don’t yet understand how and why we ourselves care and bother, so we’d be hard put to install that capacity inside our robot vacuum cleaners.
Japan’s Robot Revolution — Fugitt said Japan’s weakness was in application and deployment of its advanced technologies. “The Japanese expect other countries and people to appreciate their technology, but they’re inwardly focused. If it doesn’t make sense to them, they typically don’t do it,” he said, citing the example of Japanese advanced wheelchairs having 100 kilogram weight limits. […] South Korea could be a threat [to Japan’s lead in robotics] if the chaebol opened up [and shared technologies], but I don’t see it happening. The U.S. will come in and disrupt things; they’ll cause chaos in a particular market and then run away.
A World Without Work (The Atlantic) — In 1962, President John F. Kennedy said, “If men have the talent to invent new machines that put men out of work, they have the talent to put those men back to work.” […] Technology creates some jobs too, but the creative half of creative destruction is easily overstated. Nine out of 10 workers today are in occupations that existed 100 years ago, and just 5% of the jobs generated between 1993 and 2013 came from “high tech” sectors like computing, software, and telecommunications.
Computer of Wired-Together Rat Brains — this is ALL THE AMAZING. a Brainet that allows three monkeys connected at the brain to control a virtual arm on screen across three axes. […] Nicolelis said that, essentially, he created a “classic artificial neural network using brains.” In that sense, it’s not artificial at all. (via Slashdot)
Reactions — Slack turns emoji into first-class interactions. Genius!
Pixar’s Scientific Method — If you turn your head without moving your eyes first, it looks like you’re dead. Now there’s your uncanny valley.
AWS CodePipeline — latest in Amazon’s build-out of cloud tools. Interchangeable commodity platforms regaining lockin via higher-order less-interchangeable tooling for deployment, config, monitoring, etc.
Netflix and the Conservation of Attractive Profits (Stratechery) — Note the common element to all three of these companies: all have managed to modularize the production/delivery of their service which has allowed them to move closer to the customer. To put it another way, all of this new value is being created by specialized CRM companies: Airbnb for travelers, Uber for commuters, and Netflix for the bored.
Go as Open Source — keynote from this year’s Gophercon. I’ve been pondering lately how successful open source projects go beyond “anyone can scratch their itch,” and instead actively manage the tendency for scope creep. We’d rather have a small number of features that enable, say, 90% of the target use cases, and avoid the orders of magnitude more features necessary to reach 99% or 100%.
The Universal Data Structure — Given the abysmal state of of today’s software engineering, I believe that a full embrace of the universal hash will result in better, simpler programs. Your weekly dose of snark.
Google Patenting Machine Learning Developments (Reddit) — I am afraid that Google has just started an arms race, which could do significant damage to academic research in machine learning. Now it’s likely that other companies using machine learning will rush to patent every research idea that was developed in part by their employees. We have all been in a prisoner’s dilemma situation, and Google just defected. Now researchers will guard their ideas much more combatively, given that it’s now fair game to patent these ideas, and big money is at stake.
Machine Ethics (Nature) — machine learning ethics versus rule-driven ethics. Logic is the ideal choice for encoding machine ethics, argues Luís Moniz Pereira, a computer scientist at the Nova Laboratory for Computer Science and Informatics in Lisbon. “Logic is how we reason and come up with our ethical choices,” he says. I disagree with his premises.
CS 61AS — Berkeley self-directed Structure and Interpretation of Computer Programs course.
Harbingers of Failure (PDF) — We show that some customers, whom we call ‘Harbingers’ of failure, systematically purchase new products that flop. Their early adoption of a new product is a strong signal that a product will fail – the more they buy, the less likely the product will succeed. Firms can identify these customers either through past purchases of new products that failed, or through past purchases of existing products that few other customers purchase.
DeepDream — the software that’s been giving the Internet acid-free trips.
In-Flight WiFi Business — numbers and context for why some airlines (JetBlue) have fast free in-flight wifi while others (Delta) have pricey slow in-flight wifi. Four years ago ViaSat-1 went into geostationary orbit, putting all other broadband satellites to shame with 140 Gbps of total capacity. This is the Ka-band satellite that JetBlue’s fleet connects to, and while the airline has to share that bandwidth with homes across of North America that subscribe to ViaSat’s Excede residential broadband service, it faces no shortage of capacity. That’s why JetBlue is able to deliver 10-15 Mbps speeds to its passengers.
British Library Digitising Newspapers (The Guardian) — as well as photogrammetry methods used in the Great Parchment Book project, Terras and colleagues are exploring the potential of a host of techniques, including multispectral imaging (MSI). Inks, pencil marks, and paper all reflect, absorb, or emit particular wavelengths of light, ranging from the infrared end of the electromagnetic spectrum, through the visible region and into the UV. By taking photographs using different light sources and filters, it is possible to generate a suite of images. “We get back this stack of about 40 images of the [document] and then we can use image-processing to try to see what is in [some of them] and not others,” Terras explains.
Testing a Distributed System (ACM) — This article discusses general strategies for testing distributed systems as well as specific strategies for testing distributed data storage systems.
The Storage Tipping Point — the performance optimization technologies of the last decade – log structured file systems, coalesced writes, out-of-place updates and, soon, byte-addressable NVRAM – are conflicting with similar-but-different techniques used in SSDs and arrays. The software we use is written for dumb storage; we’re getting smart storage; but smart+smart = fragmentation, write amplification, and over-consumption.
pushpin — a reverse proxy server that makes it easy to implement WebSocket, HTTP streaming, and HTTP long-polling services. It communicates with backend web applications using regular, short-lived HTTP requests (GRIP protocol). This allows backend applications to be written in any language and use any webserver.
The Gold Standard Checklist for Web Components — This is a working draft of a checklist to define a “gold standard” for web components that aspire to be as predictable, flexible, reliable, and useful as the standard HTML elements.
How Not to be Wrong: The Power of Mathematical Thinking (Amazon) — Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, what Facebook can and can’t figure out about you, and the existence of God.

What Turing Himself Said About the Imitation Game (IEEE) — fascinating history. The second myth is that Turing predicted a machine would pass his test around the beginning of this century. What he actually said on the radio in 1952 was that it would be “at least 100 years” before a machine would stand any chance with (as Newman put it) “no questions barred.”
Running Effective Retrospectives — Each change to the team’s workflow is treated as a scientific experiment, whereby a hypothesis is formed, data collected, and expectations compared with actual results.
IRS Finally Agrees to Release Non-Profit Records (BoingBoing) — Today, the IRS released a statement saying they’re going to do what we’ve been hoping for, saying they are going to release e-file data and this is a “priority for the IRS.” Only took $217,000 in billable lawyer hours (pro bono, thank goodness) to get there.
Compiler Errors for Humans — it’s so important, and generally underbaked in languages. A decade or more ago, I was appalled by Python’s errors after Perl’s very useful messages. Today, appreciating Go’s generally handy errors. How a system handles the operational failures that will inevitably occur is part and parcel of its UX.
The Internet of Things That Do What You Tell Them: Cory Doctorow passionately explains how computers are already entwined in our lives, which means laws that support lock-in are much more than inconveniences.
