Four short links: 26 August 2009

Food, NoSQL, Brain Power, Social Data

  1. Better BBQ Through Chemistry — food is the perfect ground for geek training: there are measurements, there’s science, it’s easy to know whether you’ve succeeded, and you can eat all but the worst of your failures. (via BoingBoing)
  2. NoSQL (East) — conference on East Coast for relationless databases.
  3. Human Brain Processing Speed — clocked at 60bits/second, according to this MIT Technology Review article. Their approach eventually led to Hick’s Law, one of the few laws of experimental psychology. It states that the time it takes to make a choice is linearly related to the entropy of the possible alternatives. The results from various reaction-time experiments seem to show that this is the case. Although one byproduct of this approach is that the results are intimately linked to the type of experiment used to measure the reaction time. And that makes each study peculiarly vulnerable to the idiosyncrasies of the experimental approach. Today, Fermi Moscoso del Prado Martín from the Université de Provence in France proposes a new way to study reaction times by analyzing the entropy of their distribution, rather in the manner of thermodynamics.

  4. Truly Social DataData will only be truly social when you can work with it in the kinds of ways we work with information in the real, non-computational, world. In the real world we don’t ask for permission to have an opinion on something, to add to the ball of information surrounding a concept. Our needs don’t have to be anticipated by programmers. We can share information as we please. For example, nobody owns the concept of Barcelona. If I want to essentially “tag” Barcelona as being hot, or noisy, or beautiful, I just do it. I can keep my opinion private, I can share it with certain others, I can hold conflicting opinions, I can organize things in multiple ways at the same time and give things many names.
