Forward Secrecy for HTTPS — Google contributed a better HTTPS cipher suite to OpenSSL, one that doesn’t share keys between conversations. Yay the Goog for giving back.
Ratings Systems (Quora) — very good answer from the VP of Engineering at Netflix about the purposes and effects of different ratings and feedback systems. Full of pithy and true guidelines like: Your users have a certain mental budget they will invest in your rating system. The more work you make each decision, the fewer decisions you will get. This is true in many contexts other than rating systems as well. You can’t randomly throw feedback mechanisms into your app, you must design them as deliberately and thoughtfully as the rest of your site.
InstaCSS — very simple very useful reference site. Grod like simplicity.
Libraries: Where It All Went Wrong — I was asked to provocatively help focus librarians on the opportunities offered to libraries in the Internet age. If I ask you to talk about your collections, I know that you will glow as you describe the amazing treasures you have. When you go for money for digitization projects, you talk up the incredible cultural value. ANZAC! Constitution! Treaties! Development of a nation! But then if I look at the results of those digitization projects, I find the shittiest websites on the planet. It’s like a gallery spent all its money buying art and then just stuck the paintings in supermarket bags and leaned them against the wall.

On the Perpetuation of Ignorance (PDF) — ignorance about an issue leads to dependence leads to government trust leads to avoidance of information about that issue. Again I say to Gov 2.0 advocates that simply making data available doesn’t generate a motivated, engaged, change-making citizenry. (via Roger Dennis)
Science Hack Day SF Videos (justin.tv) — the demos from Science Hack Day SF. The journey of a thousand miles starts with a Hack Day.
A Cross-Sectional Study of Canine Tail-Chasing and Human Responses to It, Using a Free Video-Sharing Website (PLoSone) — Approximately one third of tail-chasing dogs showed clinical signs, including habitual (daily or “all the time”) or perseverative (difficult to distract) performance of the behaviour. These signs were observed across diverse breeds. Clinical signs appeared virtually unrecognised by the video owners and commenting viewers; laughter was recorded in 55% of videos, encouragement in 43%, and the commonest viewer descriptors were that the behaviour was “funny” (46%) or “cute” (42%).
RSS Died For Your Sins (Danny O’Brien) — if you have seven thousand people following you, a good six thousand of those are going to be people you don’t particularly like. The problem, as ever, is—how do you pick out the other thousand? Especially when they keep changing? I firmly believe that one of the pressing unsolved technological problems of the modern age is getting safely away from people you don’t like, without actually throttling them to death beforehand, nor somehow coming to the conclusion that they don’t exist, nor ending up turning yourself into a hateful monster.
Generating Text from Functional Brain Images (Frontiers in Human Neuroscience) — We built a model of the mental semantic representation of concrete concepts from text data and learned to map aspects of such representation to patterns of activation in the corresponding brain image. Turns out that the clustering of concepts in Wikipedia is similar to how they’re clustered in the brain. They found clusters in Wikipedia, mapped to the brain activity for known words, and then used that mapping to find words for new images of brain activity. (via The Economist)
Ancient Lives — crowdsourced translation and reconstruction of ancient papyri from Oxyrhyncus, already found new gospels (in which the number of the beast is 616, not 666).

The Flashed Face Effect Video — your brain is not perfect, and it reduces faces to key details. When they flash by in the periphery of your vision, you perceive them as gross and freakish. I like to start the week by reminding myself how fallible I am. Good preparation for the rest of the week… (via BERG London)
The Newsonomics of Netflix and the Digital Shift — Netflix changed prices, tilting people toward digital and away from physical. This post argues that the same will happen in newspapers. Imagine 2020, and the always-out-there-question: Will we still have print newspapers? Well, maybe, but imagine how much they’ll cost — $3 for a local daily? — and consumers will compare that to the “cheap” tablet pricing, and decide, just as they doing now are with Netflix, which product to take and which to let go. The print world ends not with a bang, but with price increase after price increase. (via Tim O’Reilly)
Phonegap — just shipped 1.0 of an HTML5 app platform that allows you to author native applications with web technologies and get access to APIs and app stores.
UnQL — query language for document store databases, from the creators of CouchDB and SQLite. (via Francisco Reyes)
How Online Companies Get You to Spend More and Share More (Wired) — Dan Ariely (“Predictably Irrational”) tackles Amazon, Netflix, Groupon, etc. and shows how their web design ties into studies of our cognitive biases. This is great post-hoc analysis, but I’d love to know whether it’s predictive: can you say “do X, in line with study Y” and conversions always increase?

Digging into Technology’s Past — stories of the amazing work behind the visual 6502 project and how they reconstructed and simulated the legendary 6502 chip. To analyze and then preserve the 6502, James treated it like the site of an excavation. First, he needed to expose the actual chip by removing its packaging of essentially “billiard-ball plastic.” He eroded the casing by squirting it with very hot, concentrated sulfuric acid. After cleaning the chip with an ultrasonic cleaner—much like what’s used for dentures or contact lenses—he could see its top layer.
Too Many Public Works Built on Rosy Scenarios (Bloomberg) — a feedback loop with real data being built to improve accuracy estimating infrastructure project costs. He would like to see better incentives — punishment for errors, rewards for accuracy — combined with a requirement that forecasts not only consider the expected characteristics of the specific project but, once that calculation is made, adjust the estimate based on an “outside view,” reflecting the cost overruns of similar projects. That way, the “unexpected” problems that happen over and over again would be taken into consideration.
Such scrutiny would, of course, make some projects look much less appealing — which is exactly what has happened in the U.K., where “reference-class forecasting” is now required. “The government stopped a number of projects dead in their tracks when they saw the forecasts,” Flyvbjerg says. “This had never happened before.”
Neurovigil Gets Cash Injection To Read Your Mind (FastCompany) — “an anonymous American industrialist and technology visionary” put tens of millions into this company, which has hardware to gather mineable data. iBrain promises to open a huge pipeline of data with its powerful but simple brain-reading tech, which is gaining traction thanks to technological advances. But the other half of the potentailly lucrative equation is the ability to analyze the trove of data coming from iBrain. And that’s where NeuroVigil’s SPEARS algorithm enters the picture. Not only is the company simplifying collection of brain data with a device that can be relatively comfortably worn during all sorts of tasks–sleeping, driving, watching advertising–but the combination of iBrain and SPEARS multiplies the efficiency of data analysis.

Multitasking Brains (Wired) — interesting pair of studies: old brains have trouble recovering from distractions; hardcore multitaskers have trouble focusing. (via Stormy Peters)
Social Privacy — Danah Boyd draft paper on teens’ attitudes to online privacy. Interesting take on privacy as about power: This incident does not reveal that teens don’t understand privacy, but rather that they lack the agency to assert social norms and expect that others will respect them.
