If anyone from HN would like to attend the event, please use the registration code HackerNews100417 and register at http://tedxcam.com/registration/
I look forward to seeing the conference and meeting some other UK based HNers.
These are almost all free.
We will have our first ever TED in Montevideo, Uruguay: http://www.tedxmontevideo.org/
If you understand Spanish, I really recommend Nicolás Jodal who is our most influential enterpreneur and gives great talks.
Miguel Brechner will probably speak about the OLPC project (which was at its most succesful here in Uruguay) as he did in Buenos Aires: http://tedxbuenosaires.org/?page_id=11
The payment page uses Hypertext Transfer Protocol Secure (HTTPS). I suspect you didn't notice this because we use a framed address bar to white label the service provided by Amiando. The fixed URI http://www.tedxcam.com/registration does not refresh to show the HTTP to HTTPS when redirected to the payment page, however, if you were to view this frame in a new window you would in fact see you've been redirected to https://www.amiando.com/TEDxCam.html – a secure web page.
To avoid this confusion and be certain your card details are safely processed, please register via the following address: http://www.amiando.com/TEDxCam.html (which will transfer you to https protocol).
