- Exploiting a Bug in Google Glass — unbelievably detailed and yet easy-to-follow explanation of how the bug works, how the author found it, and how you can exploit it too. The second guide was slightly more technical, so when he returned a little later I asked him about the Debug Mode option. The reaction was interesting: he kind of looked at me, somewhat confused, and asked “wait, what version of the software does it report in Settings”? When I told him “XE4″ he clarified “XE4, not XE3″, which I verified. He had thought this feature had been removed from the production units.

- The Index-Based Subgraph Matching Algorithm (ISMA): Fast Subgraph Enumeration in Large Networks Using Optimized Search Trees (PLoSONE) — The central question in all these fields is to understand behavior at the level of the whole system from the topology of interactions between its individual constituents. In this respect, the existence of network motifs, small subgraph patterns which occur more often in a network than expected by chance, has turned out to be one of the defining properties of real-world complex networks, in particular biological networks. […] An implementation of ISMA in Java is freely available.

Analytics vs Learning, Reproducible Science, Ramping up Military Internet Attacks, and Compressed Sensing
- Analytics for Learning — Since doing good learning analytics is hard, we often do easy learning analytics and pretend that they are good instead. But pretending doesn’t make it so. (via Dan Meyer)
- Reproducible Research — a list of links to related work about reproducible research, reproducible research papers, etc. (via Stijn Debrouwere)
- Pentagon Deploying 100+ Cyber Teams — The organization defending military networks — cyber protection forces — will comprise more than 60 teams, a Pentagon official said. The other two organizations — combat mission forces and national mission forces — will conduct offensive operations. I’ll repeat that: offensive operations.
- Towards Deterministic Compressed Sensing (PDF) — instead of taking lots of data, compressing by throwing some away, can we only take a few samples and reconstruct the original from that? (more mathematically sound than my handwaving explanation). See also Compressed sensing and big data from the Practical Quant. (via Ben Lorica)
Inside the Aaron Swartz Investigation, Multivariate Dataset Exploration, Augmediated Life, and Public Experience
- Life Inside the Aaron Swartz Investigation — do hard things and risk failure. What else are we on this earth for?
- Steve Mann: My Augmediated Life (IEEE) — Until recently, most people tended to regard me and my work with mild curiosity and bemusement. Nobody really thought much about what this technology might mean for society at large. But increasingly, smartphone owners are using various sorts of augmented-reality apps. And just about all mobile-phone users have helped to make video and audio recording capabilities pervasive. Our laws and culture haven’t even caught up with that. Imagine if hundreds of thousands, maybe millions, of people had video cameras constantly poised on their heads. If that happens, my experiences should take on new relevance.
- The Google Glass Feature No-One Is Talking About — The most important Google Glass experience is not the user experience – it’s the experience of everyone else. The experience of being a citizen, in public, is about to change.
Design compels. Math is proof. Both sides will defend their domains at Strata's next Great Debate.
At Strata Santa Clara later this month, we’re reprising what has become a tradition: Great Debates. These Oxford-style debates pit two teams against one another to argue a hot topic in the fields of big data, ubiquitous computing, and emerging interfaces.
Part of the fun is the scoring: attendees vote on whether they agree with the proposal before the debaters; and after both sides have said their piece, the audience votes again. Whoever moves the needle wins.
This year’s proposition — that design matters more than math — is sure to inspire some vigorous discussion. The argument for math is pretty strong. Math is proof. Given enough data — and today, we have plenty — we can know. “The right information in the right place just changes your life,” said Stewart Brand. Properly harnessed, the power of data analysis and modeling can fix cities, predict epidemics, and revitalize education. Abused, it can invade our lives, undermine economies, and steal elections. Surely the algorithms of big data matter!
But your life won’t change by itself. Bruce Mau defines design as “the human capacity to plan and produce desired outcomes.” Math informs; design compels. Without design, math can’t do its thing. Poorly designed experiments collect the wrong data. And if the data can’t be understood and acted upon, it may as well not have been crunched in the first place.
This is the question we’ll be putting to our debaters: Which matters more? A well-designed collection of flawed information — or an opaque, hard-to-parse, but unerringly accurate model? From mobile handsets to social policy, we need both good math and good design. Which is more critical? Read more…

Practical advice for those considering a career in data science
When I was a youngster in college I found myself dissatisfied after I took a stats class from the math department. So I decided to take another stats class. Classmates thought I was crazy. Let’s be real, what precocious over-achieving teenager majoring in English lit seeks to retake a math class? And not because of a grade but because they were dissatisfied with what they didn’t get out of it? After a bit of research, I decided to take the stats class offered by the psych department.
It made a significant difference.
Thinking about math from the perspectives of research design methodology and how data can be used to manipulate people made quite an impact on my teenage worldview. This experience also reinforced my belief that education is what you decide it will be. There is always more than one way to learn and education doesn’t necessarily have to happen in a physical classroom. Growing up in the San Francisco Bay Area where friends and loved ones decided to forgo traditional higher ed completely to start their own companies or immediately work in jobs in technology also contributed to this belief.
While full time students who are looking at a career in data science may have the time to do seemingly nutty things like take overlapping math classes, this is not something that most people with full time jobs are able to do. When people with full time jobs ask me about what they need to do to move into data science, I probe them about the kind of job in data science they want and about their analytical and empathy skills. Then, I immediately follow up with “So, how are your math skills?.” Interestingly enough, I get a lot people saying how they don’t have time to physically go into a classroom or that it has been, like, forever since they’ve used statistics and/or linear algebra for data analysis. Even more interesting is how often people don’t realize just how many resources are available to learn math outside of the physical-attendance-in-a-classroom-model.

ID-based Democracy, Web Documentation, American Telco Gouging, and Stats Cookbook
- Finland Crowdsourcing New Laws (GigaOm) — online referenda. The Finnish government enabled something called a “citizens’ initiative”, through which registered voters can come up with new laws – if they can get 50,000 of their fellow citizens to back them up within six months, then the Eduskunta (the Finnish parliament) is forced to vote on the proposal. Now this crowdsourced law-making system is about to go online through a platform called the Open Ministry. Petitions and online voting are notoriously prone to fraud, so it will be interesting to see how well the online identity system behind this holds up.
- WebPlatform — wiki of information about developing for the open web. Joint production of many of the $BIGCOs of the web and the W3C, so will be interesting to see, as it develops, whether it has the best aspects of each or the worst.
