Reith Lectures — this year’s lectures are by Atul Gawande, talking about preventable failure and systemic improvement — topics of particular relevance to devops cultural devotees. (via BoingBoing)
Chinese Mobile App UI Trends — interesting differences between US and China. Phone number authentication interested me: You key in your number and receive a confirmation code via SMS. Here, all apps offer this type of phone number registration/login (if not prefer it). This also applies to websites, even those without apps. (via Matt Webb)
A Critique of the Balancing Metaphor in Privacy and Security — The arguments presented by this paper are built on two underlying assertions. The first is that the assessment of surveillance measures often entails a judgement of whether any loss in privacy is legitimised by a justifiable increase in security. However, one fundamental difference between privacy and security is that privacy has two attainable end-states (absolute privacy through to the absolute absence of privacy), whereas security has only one attainable end-state (while the absolute absence of security is attainable, absolute security is a desired yet unobtainable goal). The second assertion, which builds upon the first, holds that because absolute security is desirable, new security interventions will continuously be developed, each potentially trading a small measure of privacy for a small rise in security. When assessed individually each intervention may constitute a justifiable trade-off. However, when combined together, these interventions will ultimately reduce privacy to zero. (via Alistair Croll)
ISP Interconnection and its Impact on Consumer Internet Performance (Measurement Lab) — In researching our report, we found clear evidence that interconnection between major U.S. access ISPs (AT&T, Comcast, CenturyLink, Time Warner Cable, and Verizon) and transit ISPs Cogent, Level 3, and potentially XO was correlated directly with degraded consumer performance throughout 2013 and into 2014 (in some cases, ongoing as of publication). Degraded performance was most pronounced during peak use hours, which points to insufficient capacity and congestion as a causal factor. Further, by noting patterns of performance degradation for access/transit ISP pairs that were synchronized across locations, we were able to conclude that in many cases degradation was not the result of major infrastructure failures at any specific point in a network, but rather connected with the business relationships between ISPs.
Build Quality In — an e-book collection of Continuous Delivery and DevOps experience reports from the wild. Work in progress, and a collection of accumulated experience in the new software engineering practices can’t be a bad thing.
Designing for Large-Screen Cellphones (Luke Wroblewski) — In his analysis of 1,333 observations of smartphones in use, Steven Hoober found about 75% of people rely on their thumb and 49% rely on a one-handed grip to get things done on their phones. On large screens (over four inches) those kinds of behaviors can stretch people’s thumbs well past their comfort zone as they try to reach controls positioned at the top of their device. Design advice to create interactions that don’t strain tendons or gray matter.
fastsocket (Github) — a highly scalable socket and its underlying networking implementation of Linux kernel. With the straight linear scalability, Fastsocket can provide extremely good performance in multicore machines.
Robotics Has Too Many Dreamers, Needs More Practical People (IEEE) — Grishin said that while looking for business opportunities, he saw too may entrepreneurs proposing cool new robots and concepts but with no business cases to support them. The robotics industry, he added, needs more startups to fail to allow entrepreneurs to learn from past mistakes and come up with more enduring plans. A reminder that first to found rarely correlates to biggest exit.
Fixing the Internet for Confidentiality and Security (Mark Shuttleworth) — Every society, even today’s modern Western society, is prone to abusive governance. We should fear our own darknesses more than we fear others. I like the frame of “confidentiality” vs “privacy”.
Bootstrap Material Design — a material design theme for Bootstrap. Material design (Google’s new design metaphor/language for interactive UIs) is important, to mobile and web what HIG was to MacOS, and it specifically tackles the noisy surprises that are app and web interfaces today.
Simon Wardley on Bitcoin — Why I think US will adopt bitcoin … it is currently backed by $284m in venture capital, you’re going to get it whether you like it or not.
Distributed Systems Theory for the Distributed Systems Engineer — I tried to come up with a list of what I consider the basic concepts that are applicable to my every-day job as a distributed systems engineer; what I consider ‘table stakes’ for distributed systems engineers competent enough to design a new system.
Shenzhen Trip Report (Joi Ito) — full of fascinating observations about how the balance of manufacturing strength has shifted in surprising ways. The retail price of the cheapest full featured phone is about $9. Yes. $9. This could not be designed in the US – this could only be designed by engineers with tooling grease under their fingernails who knew the manufacturing equipment inside and out, as well as the state of the art of high-end mobile phones.
Sproutling — The world’s first sensing, learning, predicting baby monitor. A wearable band for your baby, a smart charger and a mobile app work together to not only monitor more effectively but learn and predict your baby’s sleep habits and optimal sleep conditions. (via Wired)
Notes on the Celebrity Data Theft — wonderfully detailed analysis of how photos were lifted, and the underground industry built around them. This was one of the most unsettling aspects of these networks to me – knowing there are people out there who are turning over data on friends in their social networks in exchange for getting a dump of their private data.
Machine Learning for Plant Properties — startup building database of plant genomics, properties, research, etc. for mining. The more familiar you are with your data and its meaning, the better your machine learning will be at suggesting fruitful lines of query … and the more valuable your startup will be.
Dissecting Message Queues — throughput, latency, and qualitative comparison of different message queues. MQs are to modern distributed architectures what function calls were to historic unibox architectures.
1915 Data Visualization Rules — a reminder that data visualization is not new, but research into effectiveness of alternative presentation styles is.
Viv — another step in the cognition race. Wolfram Alpha was first out the gate, but Watson, Viv, and others are hot on heels of being able to parse complex requests, then seek and use information to fulfil them.
Universal Mobile Electrochemical Detector Designed for Use in Resource-limited Applications (PNAS) — $35 handheld sensor with mobile phone connection. The electrochemical methods that we demonstrate enable quantitative, broadly applicable, and inexpensive sensing with flexibility based on a wide variety of important electroanalytical techniques (chronoamperometry, cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, and potentiometry), each with different uses. Four applications demonstrate the analytical performance of the device: these involve the detection of (i) glucose in the blood for personal health, (ii) trace heavy metals (lead, cadmium, and zinc) in water for in-field environmental monitoring, (iii) sodium in urine for clinical analysis, and (iv) a malarial antigen (Plasmodium falciparum histidine-rich protein 2) for clinical research.

Thumbstopping (Salon) — The prime goal of a Facebook ad campaign is to create an ad “so compelling that it would get people to stop scrolling through their news feeds,” reports the Times. This is known, in Facebook land, as a “thumbstopper.” And thus, the great promise of the digitial revolution is realized: The best minds of our generation are obsessed with manipulating the movement of your thumb on a smartphone touch-screen.
Microsoft’s Development Practices (Ars Technica) — they get the devops religion but call it “combined engineering”. They get the idea of shared code bases, but call it “open source”. At least when they got the agile religion, they called it that. Check out the horror story of where they started: a two-year development process in which only about four months would be spent writing new code. Twice as long would be spent fixing that code. MSFT’s waterfall was the equivalent of American football, where there’s 11 minutes of actual play in the average 3h 12m game.
