Need a Google Wave invite? Just add a (nice) comment

Posted by Harry Seldon on November 29, 2009

I have got 8 remaining invites for Google Wave. If you want one, just add a (nice) comment below with your email in the email field (not in the comment itself). I will invite you from Google Wave, asap. It will take a day or two before you receive an email from Google that will give you the actual access to Wave.

Once you are surfing the wave, remember, to search for public waves, use this query: with:public. To search for French public waves, use with:public tag:fr.

If you want to create a public wave:

  • Add public@a.gwave.com to your contact list (press enter even if it tells you the user does not exist)
  • Create a wave and add this contact.

Enjoy Wave.

For Taleb's Black Swan's Readers, Mediocristan and Extremistan are Stable and Unstable Systems

Posted by Harry Seldon on November 02, 2009

As a control system engineer and Mandelbrot/Taleb fan, I want to bring this quick clarification (It will be worth a longer post another day):

Extremistan is the world of unstable systems (predicting a final state on an unstable system is a mathematical nonsense and predicting a transient state is computationnally impossible).
Extremistan is the fractal world of Mandelbrot.

Mediocristan is the world of stable systems (you can predict the final state and even the transient if you are good but it is already difficult to predict the transient state for a stable system).
Mediocristan is the Linear / Gaussian Paradise.
