The 2016 HackMiami Conference will be coming up in a few months on May 13-15. This will be the fourth time for this annual conference. Been to every one and plan on attending again as I will be speaking (for the second time).
A change for this year is they have a new venue: Miami Beach Deauville Beach Resort. I think they had some problems with the prior location. Hopefully things will be better with this one.
They have announced their keynote speakers, and John McAfee is returning as an announced speaker. (last year he was a surprise keynote speaker). This year's general theme is a return to the start of the hacker/cracker culture. They are still taking proposals, so don't yet know what will be the speakers and tracks. There will again be the lockpick village and "capture the flag" event as before, and training on the first day.
If you are in Florida, check out this conference. It's a lot of fun.
