ReWalk Robotics Exoskeleton — first exoskeleton for the paralyzed to receive regulatory approval; 66 bought so far, 11 with reimbursement from insurance. The software upgrades for the ReWalk 6.0 provide a smoother walking gait (with less of a soldier-like marching step), an easier stopping mechanism, and a much-improved mode for ascending and descending stairs. The user wears a wristwatch-like controller to switch the suit between sit, stand, walk, and stair modes. How long until a cheaper version hits the market, but you don’t always get to control where it takes you if there’s a sale on featuring brands you love? (via IEEE)
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.
WebAssembly (Luke Wagner) — new standard, WebAssembly, that defines a portable, size- and load-time-efficient format and execution model specifically designed to serve as a compilation target for the Web. Being worked on by Mozilla, Google, Microsoft, and Apple.
Inceptionism: Going Deeper into Neural Networks (Google Research) — stunningly gorgeous gallery of images made by using a deep image-classification neural net to make the picture “more.” (So, if the classifier says the pic is of a cat, randomly twiddle pixels until the image classifier says “wow, that matches `cat’ even better!”)
The Automated Workplace (Ben Brown) — What happens if this process is automated using a “bot” in an environment like Slack? — repeat for all business processes. (via Matt Webb)
Conversational UIs (Matt Webb) — a new medium needs a new grammar and conversational UIs are definitely a new medium. As someone whose wedding vows were exchanged on a TinyMUSH, conversational UIs are near and dear to my heart.
Teach Don’t Tell — what I think good documentation is and how I think you should go about writing it. Sample common sense: This is obvious when you’re working face-to-face with someone. When you tell them how to play a C major chord on the guitar and they only produce a strangled squeak, it’s clear that you need to slow down and talk about how to press down on the strings properly. As programmers, we almost never get this kind of feedback about our documentation. We don’t see that the person on the other end of the wire is hopelessly confused and blundering around because they’re missing something we thought was obvious (but wasn’t). Teaching someone in person helps you learn to anticipate this, which will pay off (for your users) when you’re writing documentation.
The Basic AI Drives (PDF) — Surely, no harm could come from building a chess-playing robot, could it? In this paper, we argue that such a robot will indeed be dangerous unless it is designed very carefully. Without special precautions, it will resist being turned off, will try to break into other machines and make copies of itself, and will try to acquire resources without regard for anyone else’s safety. These potentially harmful behaviors will occur not because they were programmed in at the start, but because of the intrinsic nature of goal-driven systems.
PreTTY — how to take a good-looking screencap of your terminal app in action.
Using Logs to Build Solid Data Infrastructure — (Martin Kleppmann) — For lack of a better term, I’m going to call this the problem of ‘data integration.’ With that, I really just mean ‘making sure that the data ends up in all the right places.’ Whenever a piece of data changes in one place, it needs to change correspondingly in all the other places where there is a copy or derivative of that data.
Project Advice (Daniel Bachhuber) — for leaders of distributed teams. Focus on clearing blockers above all else. Because you’re working on an open source project with contributors across many timezones, average time to feedback will optimistically be six hours. More likely, it will be 24-48 hours. This slow feedback cycle can kill progress on pull requests. As a project maintainer, prioritize giving feedback, clearing blockers, and making decisions.
YAGNI (Martin Fowler) — cost of build, cost of delay, cost of carry, cost of repair. Every product manager has felt these costs.
Rise of the Robots and Shadow Work (NY Times) — In “Rise of the Robots,” Ford argues that a society based on luxury consumption by a tiny elite is not economically viable. More to the point, it is not biologically viable. Humans, unlike robots, need food, health care and the sense of usefulness often supplied by jobs or other forms of work. Two thought-provoking and related books about the potential futures as a result of technology-driven change.
Time Lapse Mining from Internet Photos (PDF) — First, we cluster 86 million photos into landmarks and popular viewpoints. Then, we sort the photos by date and warp each photo onto a common viewpoint. Finally, we stabilize the appearance of the sequence to compensate for lighting effects and minimize flicker. Our resulting time-lapses show diverse changes in the world’s most popular sites, like glaciers shrinking, skyscrapers being constructed, and waterfalls changing course.
Git Repository of CS Papers — The intention here is to both provide myself with backups and easy access to papers, while also collecting a repository of links so that people can always find the paper they are looking for. Pull the repo and you’ll never be short of airplane/bedtime reading.
Software For Reproducible Science — This quality is indeed central to doing science with code. What good is a data analysis pipeline if it crashes when I fiddle with the data? How can I draw conclusions from simulations if I cannot change their parameters? As soon as I need trust in code supporting a scientific finding, I find myself tinkering with its input, and often breaking it. Good scientific code is code that can be reused, that can lead to large-scale experiments validating its underlying assumptions.
Tools are the Problem — Tools don’t solve problems any more; they have become the problem. There’s just too many of them, and they all include an incredible number of features that you don’t use on your site –but that users are still required to download and execute.
Elements of Scale: Composing and Scaling Data Platforms (Ben Stopford) — today’s data platforms range greatly in complexity, from simple caching layers or polyglotic persistence right through to wholly integrated data pipelines. There are many paths. They go to many different places. In some of these places at least, nice things are found. So, the aim for this talk is to explain how and why some of these popular approaches work. We’ll do this by first considering the building blocks from which they are composed. These are the intuitions we’ll need to pull together the bigger stuff later on.
Estimating Google’s 2FA Adoption — If we project out to the current day (965 days later), that’s a growth of ~25M users (25,586,975). Add that to the ~14M base number of users (13,886,058) exiting the graph and we end up at a grand total of…nearly 40 million users (39,473,033) enrolled in Google’s 2SV. NB there’s a lot on the back of this envelope.
Empathy and Product Development — None of this means that you shouldn’t A/B test or have other quantitative measure. But all of those will mean very little if you don’t have the qualitative context that only observation and usage can provide. Empathy is central to product development.
