Four short links: 5 December 2011

Spatial Search, Exposing Your Phone's Perfidity, School Unconference, and Wikipedia Viz

  1. VP Trees — a data structure for fast spatial searching. A form of nearest neighbour, useful for melodies (PDF) and image retrieval (PDF) and poetry. (via Reddit)
  2. iYou — iTunes plugin to show you all the stuff your phone collects about you.
  3. Bar Camps in Primary Schools — NZ teacher deploys bar camps among students. Great things happen.
  4. Realtime Wikipedia Edits — fascinating and hypnotic and inspirational and appalling and irrelevant all at once.
