Hi spanish-speaking GNU Taler hackers, I just finished my talk in nerdear NerdearLA 
The talk goes from explaining the concepts, components, why floss is important and then setting up a system live and using it to do a small purchase.
The target of the talk are dev, sysadmin, hacker who wants to try out new things so if you want to know more about how to set up a system in 30 mins, this talk is for you. Of course, do not follow this instruction for production deployments :) I'm just running all as root for demo purposes.
If you have any feedback, please let me know.
Some talks are in english:
* Bjarne Stroustrup will be talking about C++
* Cory Doctorow already talked about Privacy without monopoly
* Mcllroy & Kernighan are going to talk about... something nerd.
* and Vinton Cerf has a closing keynote.
Best regards from Argentina :)
