Dynamo and BigTable — good preso overview of two approaches to solving availability and consistency in the event of server failure or network partition.
Goals Gone Wild (PDF) — In this article, we argue that the beneficial effects of goal setting have been overstated and that systematic harm caused by goal setting has been largely ignored. We identify specific side effects associated with goal setting, including a narrow focus that neglects non-goal areas, a rise in unethical behavior, distorted risk preferences, corrosion of organizational culture, and reduced intrinsic motivation.
Tech Isn’t All Brogrammers (Alexis Madrigal) — a reminder that there are real scientists and engineers in Silicon Valley working on problems considerably harder than selling ads and delivering pet food to one another. (via Brian Behlendorf)
RC Grasshoppers — not a band name, an Israeli research project funded by the US Army, to remotely-control insects in flight. Instead of building a tiny plane whose dimensions would be measured in centimeters, the researchers are taking advantage of 300 million years of evolution.
What Facebook Knows (MIT Tech Review) — Analyzing the 69 billion friend connections among those 721 million people showed that the world is smaller than we thought: four intermediary friends are usually enough to introduce anyone to a random stranger. and our close friends strongly sway which information we share, but overall their impact is dwarfed by the collective influence of numerous more distant contacts—what sociologists call “weak ties.” It is our diverse collection of weak ties that most powerfully determines what information we’re exposed to.
Human Microbiome Mapped (The Scientist) — the Human Microbiome Project sequenced DNA of bacterial samples collected from 242 healthy volunteers. 3.5 terabytes of data, all accessible through public databases. One fascinating finding: Although each body part is characterised by some signature microbial groups, no species was universally present across every volunteer. “One of the HMP’s original mandates was to define the core microbiome, or the bugs that everyone shares,” said Huttenhower. “It looks like there really aren’t any.”
Kids Today Not Inattentive (Neuroskeptic) — There’s no evidence that children today are less attentive or more distractible than kids in the past, according to research just published by a team of Pennsylvania psychologists. (via Ed Yong)
Teaching Makematics at ITP (Greg Borenstein) — Computer vision algorithms, machine learning techniques, and 3D topology are becoming vital prerequisites to doing daily work in creative fields from interactive art to generative graphics, data visualization, and digital fabrication. If they don’t grapple with these subjects themselves, artists are forced to wait for others to digest this new knowledge before they can work with it.
BeWell App (Google Play) — continuously tracks user behaviors along three key health dimensions without requiring any user input — the user simply downloads the app and uses the phone as usual. Finally, someone tracking my behaviour for my own good.
Met 3D — the Metropolitan Museum of Art hosts its first 3d printing and scanning hackathon. [O]n June 1 and 2, approximately twenty-five digital artists and programmers will gather at the Met to experiment with the latest 3-D scanning and replicating technologies. Their aim will be to use the Museum’s vast encyclopedic collections as a departure point for the creation of new work. THIS. IS. AWESOME. (via Alison Marigold)
The Perfected Self (The Atlantic) — everything you knew about B. F. Skinner was wrong, and you should know about him because you’re using his techniques to lose weight, stop smoking, and do your homework. (via Erica Lloyd)
Google Blockly — (Google Code) A web-based, graphical programming language. Users can drag blocks together to build an application. No typing required. Open sourced.
How to Start a Think Tank (Guardian) — The answer to the looming crisis of legitimacy we’re facing is greater openness – not just regarding who met who at what Christmas party, but on the substance of policy. The best way to re-engage people in politics is to change how politics works – in the case of our project, to develop a more direct way for the people who use and provide public and voluntary services to create better social policy. Hear, hear. People seize on the little stuff because you haven’t given them a way to focus something big with you.
Apollo Software — amazing collection of source code to the software behind the Apollo mission. And memos, and quick references, and operations plans, and …. Just another reminder that the software itself is generally dwarfed by its operation.
Habits of Mind (PDF) — Much more important than speciﬁc mathematical results are the habits
of mind used by the people who create those results,and we envision a curriculum
that elevates the methods by which mathematics is created,the techniques used
by researchers,to a status equal to that enjoyed by the results of that research. Loved it: talks about the habits and mindsets of mathematicians, rather than the set of algorithms and postulates students must be able to recall. (via Dan Meyer)
Big Data in Finance (PDF, 9M) — Algo trading systems have begun to resemble an arms race. Competition, data, and the race for real-time.
A Parent’s Guide to 21st Century Learning (Edutopia, free registration required to download) — What should collaboration, creativity, communication, and critical thinking look like in a modern classroom? How can parents help educators accomplish their goals? We hope this guide helps bring more parents into the conversation about improving education. (via Derek Wenmoth)
Chess Intelligence and Winning — survey of IQ gaps between contestants needed to win competitions. We could view cops and killers as being involved in a grim contest. In the USA around 65% of all murders are solved. That converts to an average “murder” ELO rating difference between police and murderers of 108 ELO points. It is also known that the mean IQs of murderers and policemen are 87 and 102, respectively. So successfully solving murders is a puzzle then the “a” coefficient is 0.041, and each IQ point difference is worth 7.2 ELO points. I suspect this is masturbatory math extrapolation rather than anything significant or predictive, but the cops-vs-robbers IQ contest was an interesting angle. (via Dr Data’s Blog)
Etsy Hacker Grants: Supporting Women in Technology — Today, in conjunction with Hacker School, Etsy is announcing a new scholarship and sponsorship program for women in technology: we’ll be hosting the summer 2012 session of Hacker School in the Etsy headquarters, and we’re providing ten Etsy Hacker Grants of $5,000 each — a total of $50,000 — to women who want to join but need financial support to do so. Our goal is to bring 20 women to New York to participate, and we hope this will be the first of many steps to encourage more women into engineering at Etsy and across the industry.
The Anosognosic’s Dilemma — first part of a series on how the worst kind of ignorance is about your own failings. Even if you are just the most honest, impartial person that you could be, you would still have a problem—namely, when your knowledge or expertise is imperfect, you really don’t know it. Left to your own devices, you just don’t know it. We’re not very good at knowing what we don’t know.
Values are Features (Clay Johnson) — Google is actively investing in social and philanthropic causes, from combating human trafficking to open government. Yet it stands head and shoulders above other technology companies, and the biggest (Apple) is last in line. I just don’t see most people buying a crapper product without egregiously broken values; unless Apple is conducting human sacrifices at the Cupertino campus and it ends up on 20/20, most everyone will be happy to keep buying their iStuff.
10 Things I Learned at CrowdConf 2011 (Crowdflower) — Using his newly released crowdsourcing platform Coffee & Power, Philip [Rosedale] developed his entire company infrastructure and platform through a globally distributed workforce. 288 contributors in 127 locations worked together to get this startup off the ground in a whole new way. The Coffee & Power platform was built in 1,700 commits ranging from $6 quality checks all the way up to full source-code editing. One element of this process was developing the Hudat iPhone app. In less than a month for $2,485, the Coffee & Power community got this mobile app up and running.
