Financial Data, 21C Learning for Parents, IQ Battles, and Etsy Hacker Grants

  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 TechnologyToday, 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.

City Finances, Low-Power Computers, Future History, and Learner's Mindset

  1. California and Bust (Vanity Fair) — Michael Lewis digs into city and state finances, and the news ain’t good.
  2. Tonido Plug 2 — with only watts a day, you could have your own low-cost compute farm that runs off a car battery and a cheap solar panel.
  3. William Gibson Interview (The Paris Review) — It’s harder to imagine the past that went away than it is to imagine the future. What we were prior to our latest batch of technology is, in a way, unknowable. It would be harder to accurately imagine what New York City was like the day before the advent of broadcast television than to imagine what it will be like after life-size broadcast holography comes online. But actually the New York without the television is more mysterious, because we’ve already been there and nobody paid any attention. That world is gone.
  4. Zen and the Art of Making (Phil Torrone) — thoughts on the difference between beginners and experts, and why the beginner’s mindset is intoxicating and addictive.

Interactive Web Goodness, Location Based Security, Referer vs https, and Financial Charting

  1. Tangle — open source Javascript library for creating slider-type widgets in web pages, with built-in updating of other web elements. This is fantastic for exploring “what-if” scenarios. Check out the demos.
  2. Location-Based SecurityThe researchers have created a customized version of Android controlled by a “policy engine” on a server. The Android devices use Bluetooth and near-field communications infrastructure to determine the location of the user, and what level of access they have to what kind of information, as well as the level of functionality of their device. Security, however, is defined not by what you can do but by what the bad guys can’t do, and this seems very dependent upon external triggers (wifi and bluetooth) which are readily faked.
  3. Google Puts a Price on Privacy — I’d never realized before that https and referer information are only loosely compatible: Google has to go to efforts to restore referer information because browsers don’t pass the referer tag on when going from https (e.g., google.com) to http (e.g., your web site).
  4. Rocketcharts — open source Javascript financial charting library.

Distributed Drug Money, Science Game, Beautiful Machine Learning, and Stream Event Processing

  1. Silk Road (Gawker) — Tor-delivered “web” site that is like an eBay for drugs, currency is Bitcoins. Jeff Garzik, a member of the Bitcoin core development team, says in an email that bitcoin is not as anonymous as the denizens of Silk Road would like to believe. He explains that because all Bitcoin transactions are recorded in a public log, though the identities of all the parties are anonymous, law enforcement could use sophisticated network analysis techniques to parse the transaction flow and track down individual Bitcoin users. “Attempting major illicit transactions with bitcoin, given existing statistical analysis techniques deployed in the field by law enforcement, is pretty damned dumb,” he says. The site is viewable here, and here’s a discussion of delivering hidden web sites with Tor. (via Nelson Minar)
  2. Dr Waller — a big game using DC Comics characters where players end up crowdsourcing science on GalaxyZoo. A nice variant on the captcha/ESP-style game that Luis von Ahn is known for. (via BoingBoing)
  3. Machine Learning Demos — hypnotically beautiful. Code for download.
  4. Esper — stream event processing engine, GPLv2-licensed Java. (via Stream Event Processing with Esper and Edd Dumbill)
