Invisible Data Economy, Hacked Value, Open Algorithms Textbook, and Mobile Testing

  1. Beyond Goods and Services: The Unmeasured Rise of the Data-Driven Economy — excellent points about data as neither good nor service, and how data use goes unmeasured by economists and thus doesn’t influence policy. According to statistics from the Bureau of Economic Analysis, real consumption of ‘internet access’ has been falling since the second quarter of 2011. In other words, according to official U.S. government figures, consumer access to the Internet—including mobile—has been a drag on economic growth for the past year and a half. (via Mike Loukides)
  2. How Crooks Turn Even Crappy Hacked PCs Into Money (Brian Krebs) — show to your corporate IT overlords, or your parents, to explain why you want them to get rid of the Windows XP machines. (via BoingBoing)
  3. Open Data Structures — an open content textbook (Java and C++ editions; CC-BY licensed) on data structures. (via Hacker News)
  4. Mobiforge — test what gets sent back to mobile browsers. This site sends the HTTP headers that a mobile browser would. cf yesterday’s Responsivator. (via Ronan Cremin)

Programming Patterns, Limits of Observation, Surviving Transparency, 3D Printing Sounds

  1. Patterns for Research in Machine Learning — every single piece of advice should be tattooed under the eyelids of every beginning programmer, regardless of the field.
  2. Milton Friedman’s ThermostatEverybody knows that if you press down on the gas pedal the car goes faster, other things equal, right? And everybody knows that if a car is going uphill the car goes slower, other things equal, right? But suppose you were someone who didn’t know those two things. And you were a passenger in a car watching the driver trying to keep a constant speed on a hilly road. You would see the gas pedal going up and down. You would see the car going downhill and uphill. But if the driver were skilled, and the car powerful enough, you would see the speed stay constant. So, if you were simply looking at this particular “data generating process”, you could easily conclude: “Look! The position of the gas pedal has no effect on the speed!”; and “Look! Whether the car is going uphill or downhill has no effect on the speed!”; and “All you guys who think that gas pedals and hills affect speed are wrong!” (via Dr Data’s Blog)
  3. Transparency Doesn’t Kill Kittens (O’Reilly Radar) — Atul Gawande says, cystic fibrosis … had data for 40 years on the performance of the centers around the country that take care of kids with cystic fibrosis. They shared the data privately [...] They just told you where you stood relative to everybody else and they didn’t make that information public. About four or five years ago, they began making that information public. It’s now available on the Internet. You can see the rating of every center in the country for cystic fibrosis. Several of the centers had said, “We’re going to pull out because this isn’t fair.” Nobody ended up pulling out. They did not lose patients in hoards and go bankrupt unfairly. They were able to see from one another who was doing well and then go visit and learn from one and other.
  4. 3D Printing: The Coolest Way to Visualize Sound — just what it says. (via Infovore)

Economics of Innovation, Bio Imagery, Open Source EEG for Smartphone, and Feynman Bio

  1. Doing Capitalism in the Innovation Economy (Amazon) — soon-to-be-released book by Bill Janeway, of Warburg-Pincus (and the O’Reilly board). People raved about his session at scifoo. I’m bummed I missed it, but I’ll console myself with his book.
  2. Cell Image Librarya freely accessible, easy-to-search, public repository of reviewed and annotated images, videos, and animations of cells from a variety of organisms, showcasing cell architecture, intracellular functionalities, and both normal and abnormal processes. The purpose of this database is to advance research, education, and training, with the ultimate goal of improving human health. And an excellent source of desktop images.
  3. Smartphone EEG Scanner — unusually, there’s no Kickstarter project for an iPhone version. (Designs and software are open source)
  4. Feynman — excellent graphic novel bio of Feynman, covering the science as well as the personality. Easy to read and very enjoyable.

Being Contrary, Microsoft Tools, JOBS Doom Warnings, and Fibre ROI

  1. Change the Game (Video) — Amy Hoy’s talk from Webstock ’12, on being contrary and being successful. Was one of the standout talks for me.
  2. Rise4Funsoftware engineering tools from Microsoft Research. (via Hacker News)
  3. Why Obama’s JOBS Act Couldn’t Suck Worse (Rolling Stone) — get ready for an avalanche of shareholder suits ten years from now, since post-factum civil litigation will be the only real regulation of the startup market.
  4. Socio-economic Return Of FTTH Investment in Sweden (PDF) — This preliminary study analyses the socio-economic impacts of the investment in FTTH. The goal of the study was: Is it possible to calculate how much a krona (SEK) invested in fibre will give back to society? The conclusion is that a more comprehensive statistical data and more calculations are needed to give an exact estimate. The study, however, provides an indication that 1 SEK invested over four years brings back a minimum of 1.5 SEK in five years time. The study estimates the need for investment to achieve 100% fibre penetration, identifies and quantifies a number of significant effects of fibre deployment, and then calculates the return on investment.

Inside Personalized Advertising, Printing Presses Were Good For The Economy, Digital Access, and Ebooks in Libraries

  1. Web-Scale User Modeling for Targeting (Yahoo! Research, PDF) — research paper that shows how online advertisers build profiles of us and what matters (e.g., ads we buy from are more important than those we simply click on). Our recent surfing patterns are more relevant than historical ones, which is another indication that value of data analytics increases the closer to real-time it happens. (via Greg Linden)
  2. Information Technology and Economic Change — research showing that cities which adopted the printing press no prior growth advantage, but subsequently grew far faster than similar cities without printing presses. [...] The second factor behind the localisation of spillovers is intriguing given contemporary questions about the impact of information technology. The printing press made it cheaper to transmit ideas over distance, but it also fostered important face-to-face interactions. The printer’s workshop brought scholars, merchants, craftsmen, and mechanics together for the first time in a commercial environment, eroding a pre-existing “town and gown” divide.
  3. They Just Don’t Get It (Cameron Neylon) — curating access to a digital collection does not scale.
  4. Should Libraries Get Out of the Ebook Business? — provocative thought: the ebook industry is nascent, a small number of patrons have ereaders, the technical pain of DRM and incompatible formats makes for disproportionate support costs, and there are already plenty of worthy things libraries should be doing. I only wonder how quickly the dynamics change: a minority may have dedicated ereaders but a large number have smartphones and are reading on them already.

Why Mobile Matters, Towards Better Textbooks, Kinect Hack, and Greece Cantrepreneurial Spirit

  1. Why Mobile Matters (Luke Wroblewski) — great demonstration of the changes in desktop and mobile, the new power of Android, and the waning influence of old manufacturers.
  2. It’s Called iBooks Author Not iMathTextbooks Author, And The Trouble That Results (Dan Meyer) — It’s curious that even though students own their iBooks forever (ie. they can’t resell them or give them away), they can’t write in them except in the most cursory ways. Even curiouser, these iBooks could all be wired to the Internet and wired to a classroom through iTunes U, but they’d still be invisible to each other. Your work on your iPad cannot benefit me on mine. At our school, we look for “software with holes in it”–software into which kids put their own answers, photos, stories.
  3. DepthCamIt’s a live-streaming 3D point-cloud, carried over a binary WebSocket. It responds to movement in the scene by panning the (virtual) camera, and you can also pan and zoom around with the mouse. Very impressive hack with a Kinect! (via Pete Warden)
  4. Starting an Online Store is Not Easy in GreeceAt the health department, they were told that all the shareholders of the company would have to provide chest X-rays, and, in the most surreal demand of all, stool samples. Note to Greece: this is not how you check whether a business plan is full of shit. (via Hacker News)

DNS Benchmarking, Intro to Macroeconomics, Materials-Sensing Cameras, and 3D Printing Lab Messed Around

  1. Namebench (Google Code) — hunts down the fastest DNS servers for your computer to use. (via Nelson Minar)
  2. Primer on Macroeconomics (Jig) — reading suggestions for introductions to macroeconomics suitable to understand the financial crisis and proposed solutions. (via Tim O’Reilly)
  3. Smarter Cameras Plumb CompositionA new type of smarter camera can take a picture but also assess the chemical composition of the objects being imaged. This enables automated inspection systems to discern details that would be missed by conventional cameras. Interesting how cameras are getting smarter: Kinect as other significant case in point. (via Slashdot)
  4. Not So Open — 3D printing lab at the University of Washington had to stop helping outsiders because of a crazy new IP policy from the university administration. These folks were doing amazing work, developing and sharing recipes for new materials to print with (iced tea, rice flour, and more) (via BoingBoing)

Crowdsourced Economics, Education Gold, Meme Analytics, Hacktivism

  1. Billion Prices Project — rather than wait for official inflation figures, the BPP from MIT scans online retailer prices from around the planet. (via The Economist)
  2. Readings in Education — Dan Meyer has linked to some of the best papers he’s been reading at grad school. If you have opinions about education, or are thinking of doing something to “fix education”, you have to read Public Goods, Private Goods (PDF). It brilliantly, concisely, and clearly sums up the reason that conversations about education are so broken. The other papers Dan linked to are equally wow. Another paper (PDF) on the difference in mindsets between educational researcher and practicing teacher says: The initial [teacher] impulse is still to intervene and fix the problem, or critique the actions of the teacher who made the mistake. It also often leads students to frame their own research around educational success stories. The idea is to pick an intervention that promises to improve education—a new teaching technique, curriculum approach, instructional technology, reform effort, or administrative structure—and study it in practice. The desired outcome is that the intervention works rather well, and the function of the study is to document this and suggest how the approach could be improved in the future. This often leads to an approach to scholarship (and eventually to a kind of scholarly literature) that is relentlessly, unrealistically, sometimes comically optimistic—one that suggests that there is an implementable answer to every educational problem and that help is always on the way. He could be writing about every educational startup.
  3. Truthya research project that helps you understand how memes spread online. With our images and statistics, you can help identify misuse of Twitter. (via Pete Warden)
  4. Hackers Are Being Radicalised By Government Policy (Guardian) — As long as it seems that direct action is more effective than democratic engagement, it’s clear that the former will appear a more attractive option to many. The official line that the internet is a dangerous territory to be subdued is responsible for an alarming radicalisation. This is not just an issue for the tabloids’ oddballs and nerds, it’s an issue for everyone who believes in the fundamental importance of freedom. The Internet uprising is not causing bad regulation; bad regulation caused the Internet uprising. (via Gabriella Coleman)

Poor Economics, Shrinking Web, Orphans Put to Work, Realtime Log Monitoring

  1. Poor Economics — this is possibly the best thing I will read all year, an insightful (and research-backed) book digging into the economics of poverty. Read the lecture slides online, they’ll give you a very clear taste of what the book’s about. Love that the website is so very complementary to the book, and 100% aligned with the ambition to convince and spread the word. Kindle-purchasable, too. Sample boggle (one of many): children of children born during the Chinese famine are smaller, and children who were in utero during Ramadan earn less as adults.
  2. The Web Is Shrinking (All Things D) — graph that makes Facebook look massively important and the rest of the web look insignificant. It doesn’t take into account the nature of the interaction (shopping? research? chat?), and depends heavily on the comScore visits metric being a reliable proxy for “use”. I’d expect to see other neutral measures of “use” decreasing (e.g., searches for “school holidays”) if overall web use were decreasing, yet they don’t seem to be. Nonetheless, Facebook has become the new millennium’s AOL: keywords, grandparents, and a zealous devotion to advertising. At least Facebook doesn’t send me #&#^%*ing CDs.
  3. Orphan Works Project (University of Michigan) — library will digitize orphaned works for researchers. Lovely to see someone breaking the paralysis that orphaned works induce. (via BoingBoing)
  4. log.io — node.js system for real-time log monitoring in your browser. (via Vasudev Ram)

Fibre Horse, Forced Gold Farming, Google Correlate, Internet GDP

  1. Draft Horses Bring Fibre to Remote Locations — I love the conjunction of old and new, as draft horses prove the best way to lay fibre in remote Vermont. (via David Isenberg)
  2. Chinese Political Prisoners Gold-Farming (Guardian) — “Prison bosses made more money forcing inmates to play games than they do forcing people to do manual labour,” Liu told the Guardian. “There were 300 prisoners forced to play games. We worked 12-hour shifts in the camp. I heard them say they could earn 5,000-6,000rmb [£470-570] a day. We didn’t see any of the money. The computers were never turned off.”
  3. CorrelateGoogle Correlate finds search patterns which correspond with real-world trends. You upload your time series or geographic data, they find search terms that correlate. Very cool!
  4. McKinsey Internet Matters Report (PDF, free registration required) — Internet responsible for 3.4% of GDP in the countries they studied, 21% of GDP growth in last 5 years in mature countries, 2.6 jobs created for every one lost, and 75% of the Internet’s impact arises from traditional industries. Lots more like this in here. The United States captures more than 30 percent of global internet revenues and more than 40 percent of net income.
