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.
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.
Surgery Lag Time (ComputerWorld) — doctors trialling very remote surgery (1200 miles) with a simulator, to see what naglag is acceptable. At 200 milliseconds, surgeons could not detect a lag time. From 300 to 500 milliseconds, some surgeons could detect lag time, but they were able to compensate for it by pausing their movement. But at 600 milliseconds, most surgeons became insecure about their ability to perform a procedure, Smith said.
Clippy Lessons (The Atlantic) — focus groups showed women hated it, engineers threw out the data, and after it shipped … It turned out to be one of the most unpopular features ever introduced—especially among female users.
Telegram’s Bot Platform — Bots are simply Telegram accounts operated by software – not people – and they’ll often have AI features. They can do anything – teach, play, search, broadcast, remind, connect, integrate with other services, or even pass commands to the Internet of Things. (via Matt Webb)
New Wave of US Companies in China (Quartz) — Evernote and LinkedIn let the Chinese government access data and censor results. Smith believes that LinkedIn and Evernote are setting a dangerous precedent for other internet firms eying the Middle Kingdom. “More US companies are going to decide that treating the Chinese like second class information citizens is fine,” he says.
MarI/O (YouTube) — clear explanation of how an evolutionary algorithm figures out how to play Mario.
Google’s Monastic Vision for the Future of Work (New Yorker) — But it turns out that future-proofed life looks a lot like the vacuum-packed present. […] Inside, it is about turning Google into not only a lifestyle but a fully realized life. The return of the Company Town.
MapD: Massive Throughput Database Queries with LLVM and GPUs (nvidia) — The most powerful GPU currently available is the NVIDIA Tesla K80 Accelerator, with up to 8.74 teraflops of compute performance and nearly 500 GB/sec of memory bandwidth. By supporting up to eight of these cards per server, we see orders-of-magnitude better performance on standard data analytics tasks, enabling a user to visually filter and aggregate billions of rows in tens of milliseconds, all without indexing.
Why It’s Often Easier to Innovate in China than the US (Bunnie Huang) — We did some research into the legal frameworks and challenges around absorbing gongkai IP into the Western ecosystem, and we believe we’ve found a path to repatriate some of the IP from gongkai into proper open source.
Facebook Bluetooth Beacons — free for you to use and help people see more information about your business whenever they use Facebook during their visit.
Industry 4.0 — stop gagging at the term. Interesting examples of connectivity and data improving manufacturing. Human-machine interfaces: Logistics company Knapp AG developed a picking technology using augmented reality. Pickers wear a headset that presents vital information on a see-through display, helping them locate items more quickly and precisely. And with both hands free, they can build stronger and more efficient pallets, with fragile items safeguarded. An integrated camera captures serial and lot ID numbers for real-time stock tracking. Error rates are down by 40%, among many other benefits. Digital-to-physical transfer: Local Motors builds cars almost entirely through 3-D printing, with a design crowdsourced from an online community. It can build a new model from scratch in a year, far less than the industry average of six. Vauxhall and GM, among others, still bend a lot of metal, but also use 3-D printing and rapid prototyping to minimize their time to market. (via Quartz)
runC — a lightweight universal runtime container, by the Open Container Project. (OCP = multi-vendor initiative in hands of Linux Foundation)
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.
