- The Lease They Can Do (Business Week) — excellent Paul Ford piece on money, law, and music streaming services. So this is not about technology. Nor is it really about music. This is about determining the optimal strategy for mass licensing of digital artifacts.
- How Effective Is a Humanoid Robot as a Tool for Interviewing Young Children? (PLosONE) — The results reveal that the children interacted with KASPAR very similar to how they interacted with a human interviewer. The quantitative behaviour analysis reveal that the most notable difference between the interviews with KASPAR and the human were the duration of the interviews, the eye gaze directed towards the different interviewers, and the response time of the interviewers. These results are discussed in light of future work towards developing KASPAR as an ‘interviewer’ for young children in application areas where a robot may have advantages over a human interviewer, e.g. in police, social services, or healthcare applications.
- Funding: Australia’s Grant System Wastes Time (Nature, paywalled) — We found that scientists in Australia spent more than five centuries’ worth of time preparing research-grant proposals for consideration by the largest funding scheme of 2012. Because just 20.5% of these applications were successful, the equivalent of some four centuries of effort returned no immediate benefit to researchers.

Visual analysis tools are adding advanced analytics for big data
After recently playing with SAS Visual Analytics, I’ve been thinking about tools for visual analysis. By visual analysis I mean the type of analysis most recently popularized by Tableau, QlikView, and Spotfire: you encounter a data set for the first time, conduct exploratory data analysis, with the goal of discovering interesting patterns and associations. Having used a few visualization tools myself, here’s a quick wish-list of features (culled from tools I’ve used or have seen in action).
Requires little (to no) coding
The viz tools I currently use require programming skills. Coding means switching back-and-forth between a visual (chart) and text (code). It’s nice1 to be able to customize charts via code, but when you’re in the exploratory phase not having to think about code syntax is ideal. Plus GUI-based tools allow you to collaborate with many more users.
The BBC pulled data from the International Rescue Corps to create an interactive guide to emergency response efforts in a building collapse.
In the wake of recent building collapses, the BBC addressed the question of what goes into the rescue efforts by creating an interactive guide outlining how rescuers approach a collapsed building.
Leading indicators, CSS selectors, medical data sharing, DDoS visualization, and a new jQuery class
Leading Indicators: Over on O’Reilly Radar, Mike Loukides and Q Ethan McCallum come up with a few ideas for evaluating an organization’s data science program from the “outside.”
CSS Selectors as Superpowers: Simon St. Laurent hopes that “the success of CSS selectors will bring developers to look for other ways to apply pattern-matching to their markup.”
Data sharing drives diagnoses and cures, if we can get there (Parts 1 & 2): Andy Oram explores the take-aways from this year’s Sage Congress.
jQuery for Advanced Front-End Development: New jQuery class from O’Reilly School of Technology.
Infographics Game, Streaming Money, Robot Interviews, and Inefficient Science Funding
Using Logstalgia, developer Ludovic Fauvet created a video visualization of a recent DDoS attack on VideoLAN.
In the wake of a recent DDoS attack on open source software distributor VideoLAN, developer Ludovic Fauvet created a video visualization to show what the attack looked like.
Using START Global Terrorism data, Simon Rogers mapped every U.S. terror attack recorded between 1970 and 2011.
The recent terror attack at the Boston Marathon prompted the Guardian’s Simon Rogers (who will soon be Twitter’s Simon Rogers) to look into the history of attacks on U.S. soil. Using data from the START Global Terrorism Database, Rogers mapped every recorded terrorist incident in the U.S. from 1970 to 2011.
Street View Tiles Hacks, Policy Simulation, Map Tile Toolbox, and Connected Sensor Device HowTo
- HyperLapse — this won the Internet for April. Everyone else can go home. Check out this unbelievable video and source is available.
- Housing Simulator — NZ’s largest city is consulting on its growth plan, and includes a simulator so you can decide where the growth to house the hundreds of thousands of predicted residents will come from. Reminds me of NPR’s Budget Hero. Notice that none of the levers control immigration or city taxes to make different cities attractive or unattractive. Growth is a given and you’re left trying to figure out which green fields to pave.
- Converting To and From Google Map Tile Coordinates in PostGIS (Pete Warden) — Google Maps’ system of power-of-two tiles has become a defacto standard, widely used by all sorts of web mapping software. I’ve found it handy to use as a caching scheme for our data, but the PostGIS calls to use it were getting pretty messy, so I wrapped them up in a few functions. Code on github.
- So You Want to Build A Connected Sensor Device? (Google Doc) — The purpose of this document is to provide an overview of infrastructure, options, and tradeoffs for the parts of the data ecosystem that deal with generating, storing, transmitting, and sharing data. In addition to providing an overview, the goal is to learn what the pain points are, so we can address them. This is a collaborative document drafted for the purpose of discussion and contribution at Sensored Meetup #10. (via Rachel Kalmar)
Urban Data Challenge winners Adam Greenhall, Amelia Greenhall, and Jared McFarland visualized bus route activity for Zurich, San Francisco, and Geneva.
The Urban Data Challenge winners have been announced. The grand prize was awarded to the team behind the Dots on the Bus animated, interactive visualization — Adam Greenhall, Amelia Greenhall, and Jared McFarland.
The team culled public transportation data provided for the contest by Zurich, San Francisco, and Geneva from the week of October 1-7, 2012. According to the about pop-up on the visualization site, the data included “each bus, the time it arrived at each stop, and how many people got on and off (as counted by lasers), along with the lat/long of each stop and route.”
CCSC researcher Jacki Murdock created an interactive map of electricity use in LA as part of her Master's Capstone project.
California Center for Sustainable Communities (CCSC) researcher Jacki Murdock, along with advisor Yoh Kawano, GIS Coordinator at the Institute for Digital Research and Education at UCLA, has developed an interactive map of electricity use in Los Angeles at the Census block group level.
