Four short links: 12 April 2012

  1. Big Data in Finance (PDF, 9M) -- Algo trading systems have begun to resemble an arms race. Competition, data, and the race for real-time.
  2. 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)
  3. 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)
  4. 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.
