Demo Talks, Twitter Analysis, Free Courseware, Open Source VoIP

  1. Anatomy of a Y Combinator Demo Day Pitch (Bryce Roberts) — lovely deconstruction of the basic six slide show, demonstrating exactly how to give a talk with your audience in mind.
  2. Who Says What to Whom on Twitter (Yahoo! Research) — we find a striking concentration of attention on Twitter—roughly 50% of tweets consumed are generated by just 20K elite users—where the media produces the most information, but celebrities are the most followed. One of the researchers is Duncan Watts of Small Worlds fame.
  3. Saylor Foundation Free Education Initiative — notes, readings, tests, that take you through the curriculum for real university courses. Important because most online education stuff is either lectures, or course notes, but never enough for you to autodidacticise. (via Regan Mian)
  4. BlinkA state of the art, easy to use SIP client available for Mac, Windows and Linux. SIP = open standard for voice over IP. (via Simon Phipps)
