Personal Video, Open Source Sensors, Bad Science No Biscuit, and Playing the Odds

1. Skate Through NYC With A GoPro — this is the first I’ve seen of the GoPro cameras, which are two dimensions of clever. First, it’s video instrumentation for activities where we haven’t had this before. Second, it’s clever specialization of the Flip-style solid-state recording videocameras. (via Infovore)
2. Pulse Sensor — open source heart rate sensor project on Kickstarter. DIY hardware has made the quantified self phenomenon possible; look for many more gadgets that build your personal data cloud. (via Brady Forrest)
3. Science’s Bad Ideas (Peter Griffin) — a recap of a lecture by Lord Robert Winston where he the dark side of science and catalogues numerous instances where scientific progress has been accompanied by unforeseen consequences, ethical atrocities and detrimental impacts on society. [...] The overall message is that science can’t remain aloof from society, that scientists must engage and better understand the needs and concerns of society as they introduce new technologies that could bring about profound changes.
4. A Game With a Windfall For a Knowing Few — gambling is a tax on bad math, but poorly designed games sometimes rewards those who are good at math. Because of a quirk in the rules, when the jackpot reaches roughly $2 million and no one wins, payoffs for smaller prizes swell dramatically, which statisticians say practically assures a profit to anyone who buys at least$100,000 worth of tickets. During these brief periods – “rolldown weeks’’ in gambling parlance – a tiny group of savvy bettors, among them highly trained computer scientists from MIT and Northeastern University, virtually take over the game. Just three groups, including the Selbees, claimed 1,105 of the 1,605 winning Cash WinFall tickets statewide after the rolldown week in May, according to lottery records. (via Hacker News)
