Psychology of Software Architecture — a wonderful piece of writing, but this stood out: It comes down to behavioral economics and game theory. The license we choose modifies the economics of those who use our work.
Internet Users Increasingly Blocking Ads, Including on Mobiles (The Economist) — mobile networks working on ad blockers for their customers, If lots of mobile subscribers did switch it on, it would give European carriers what they have long sought: some way of charging giant American online firms for the strain those firms put on their mobile networks. Google and Facebook, say, might have to pay the likes of Deutsche Telekom and Telefónica to get on to their whitelists.
Connasence (Wikipedia) — a taxonomy of (systems) coupling. Two components are connascent if a change in one would require the other to be modified in order to maintain the overall correctness of the system. (Via Ben Gracewood.)
New Hardware and the Internet of Things (Jon Bruner) — The Internet of Things and the new hardware movement are not the same thing. The new hardware movement is driven by new tools for: Prototyping (inexpensive 3D printers, CNC machine tools, cheap and powerful microcontrollers, high-level programming languages on embedded systems); Fundraising and business development (Highway1, Lab IX); Manufacturing (PCH, Seeed); Marketing (Etsy, Quirky). The IoT is driven by: Ubiquitous connectivity; Cheap hardware (i.e., the new hardware movement); Inexpensive data processing and machine learning.
OpenCV 3.0 Released — I hadn’t realised how much hardware acceleration comes out of the box with OpenCV.
FBI: Companies Should Help us Prevent Encryption (WaPo) — as Mike Loukides says, we are in a Post-Modern age where we don’t trust our computers and they don’t trust us. It’s jarring to hear the organisation that (over-zealously!) investigates computer crime arguing that citizens should not be able to secure their communications. It’s like police arguing against locks.
cockroach — a scalable, geo-replicated, transactional datastore. The Wired piece about it drops the factoid that the creators of GIMP worked on Google’s massive BigTable-successor, Colossus. From Photoshop-alike to massive file systems. Love it.
How to Design Applied Filters — The most frequently observed issue during usability testing were filtering values changing placement when the user applied them – either to another position in the list of filtering values (typically the top) or to an “Applied filters” summary overview. During testing, the subjects were often confounded as they noticed that the filtering value they just clicked was suddenly “no longer there.”
Twitter Heron — a real-time analytics platform that is fully API-compatible with Storm […] At Twitter, Heron is used as our primary streaming system, running hundreds of development and production topologies. Since Heron is efficient in terms of resource usage, after migrating all Twitter’s topologies to it we’ve seen an overall 3x reduction in hardware, causing a significant improvement in our infrastructure efficiency.
Bayesian Truth Serum — a scoring system for eliciting and evaluating subjective opinions from a group of respondents, in situations where the user of the method has no independent means of evaluating respondents’ honesty or their ability. It leverages respondents’ predictions about how other respondents will answer the same questions. Through these predictions, respondents reveal their meta-knowledge, which is knowledge of what other people know.
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.
How to Turn a Liberal Hipster into a Global Capitalist (The Guardian) — In Zoe Svendsen’s play “World Factory at the Young Vic,” the audience becomes the cast. Sixteen teams sit around factory desks playing out a carefully constructed game that requires you to run a clothing factory in China. How to deal with a troublemaker? How to dupe the buyers from ethical retail brands? What to do about the ever-present problem of clients that do not pay? […] And because the theatre captures data on every choice by every team, for every performance, I know we were not alone. The aggregated flowchart reveals that every audience, on every night, veers toward money and away from ethics. I’m a firm believer that games can give you visceral experience, not merely intellectual knowledge, of an activity. Interesting to see it applied so effectively to business.
Why Are Eight Bits Enough for Deep Neural Networks? (Pete Warden) — It turns out that neural networks are different. You can run them with eight-bit parameters and intermediate buffers, and suffer no noticeable loss in the final results. This was astonishing to me, but it’s something that’s been re-discovered over and over again.
The Great Decoupling (HBR) — The Second Machine Age is playing out differently than the First Machine Age, continuing the long-term trend of material abundance but not of ever-greater labor demand.
OpenMP Support in LLVM — OpenMP enables Clang users to harness full power of modern multi-core processors with vector units. Pragmas from OpenMP 3.1 provide an industry standard way to employ task parallelism, while ‘#pragma omp simd’ is a simple yet flexible way to enable data parallelism (aka vectorization).
GM: That Car You Bought, We’re Really the Ones Who Own It — GM’s claim is all about copyright and software code, and it’s the same claim John Deere is making about their tractors. The TL;DR version of the argument goes something like this: cars work because software tells all the parts how to operate; the software that tells all the parts to operate is customized code; that code is subject to copyright; GM owns the copyright on that code and that software; a modern car cannot run without that software; it is integral to all systems; therefore, the purchase or use of that car is a licensing agreement; and since it is subject to a licensing agreement, GM is the owner and can allow/disallow certain uses or access. In the future, manufacturers own the secondary market.
Architectural Robots (Robohub) — The concept is named ‘Minibuilders.’ This is a group of robots each performing a specific task. The first robot layers a 15 cm (6 in) footprint or foundation, while a second and a third robot print the rest of the building by climbing over the structures they already printed and laying more material over them. This design is only possible at construction scale where printed layers are solid enough to support a robotic print head.
gigo — Fetching packages in golang can be difficult, especially when juggling multiple packages and private repositories. GIGO (Gigo Installer for Go) tries to solve that problem, effectively being the golang equivalent of Python’s pip.
Guide to Technical Development (Google) — This guide is a suggested path for university students to develop their technical skills academically and non-academically through self-paced, hands-on learning.
Immutable Infrastructure is the Future (Michael DeHaan) — The future of configuration management systems is in deploying cloud infrastructure that will later run immutable systems via an API level.
machinery — an asynchronous task queue/job queue based on distributed message passing.
Shadow Robot’s Dextrous Hand (Robohub) — The now infamous crab bisque recipe was prepared copying the exact movements of 2011 BBC MasterChef winner Tim Anderson. The robot switches on a hob, scrapes butter into the pan and adds prepared and measured ingredients – from a specific place on the worktop. But, it doesn’t do the chopping… That, says Rich, is an AI problem.
