Inside NASDAQ's Failbook, SimAustralia, Distraction Attraction, and Big Brother Says "Wash Your Hands!"

  1. Facebook IPO Tech Post-Mortem (PDF) — SEC’s analysis of the failures that led to the NASDAQ kicking Facebook’s IPO in the NADSAQ. (via Quartz)
  2. Run That Town — SimCity for real cities, from the Australian Bureau of Statistics and using real census data. No mention of whether you can make your citizens shout “Aussie Aussie Aussie, Oi Oi Oi!” after three cans of lager at an Aussie Rules game. (via John Birmingham)
  3. Maintaining Focus (The Atlantic) — excellent Linda Stone interview. We may think that kids have a natural fascination with phones. Really, children have a fascination with what-ever Mom and Dad find fascinating. If they are fascinated by the flowers coming up in the yard, that’s what the children are going to find fascinating. And if Mom and Dad can’t put down the device with the screen, the child is going to think, That’s where it’s all at, that’s where I need to be! I interviewed kids between the ages of 7 and 12 about this. They said things like “My mom should make eye contact with me when she talks to me” and “I used to watch TV with my dad, but now he has his iPad, and I watch by myself.”
  4. Networked Motion Sensors in Hospital Bathrooms (NY Times) — At North Shore University Hospital on Long Island, motion sensors, like those used for burglar alarms, go off every time someone enters an intensive care room. The sensor triggers a video camera, which transmits its images halfway around the world to India, where workers are checking to see if doctors and nurses are performing a critical procedure: washing their hands. […] the video monitoring program, run by a company called Arrowsight, has been adapted from the meat industry, where cameras track whether workers who skin animals — the hide can contaminate the meat — wash their hands, knives and electric cutters.

11 Essential Features that Visual Analysis Tools Should Have

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.

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.

Infographics Game, Streaming Money, Robot Interviews, and Inefficient Science Funding

  1. Metrico — puzzle game for Playstation centered around infographics (charts and graphs). (via Flowing Data)
  2. 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.
  3. 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.
  4. 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.
