I hope this isn't too much of a stretch. Heard it recently and thought it was really interesting. https://youtu.be/4YYvBLAF4T8
It's a stretch to expect me to click on it without you saying what it is!
About physical security.
...or why we need 17 billion Volts to make a picture.

Wouldn’t it be awesome to have a microscope which allows scientists to map atomic details of viruses, film chemical reactions, or study the processes in the interior of planets? Well, we’ve just built one in Hamburg. It’s not table-top, though: 1 billion Euro and a 3km long tunnel is needed for such a ‘free electron laser’, also called 4th generation synchrotron light source. I will talk about the basic physics and astonishing facts and figures of the operation and application of these types of particle accelerators.
Most people have heard about particle accelerators, most prominently LHC, at which high energy particles are brought to collision in order to study fundamental physics. However, in fact most major particle accelerators in the world are big x-ray microscopes.
The latest and biggest of these synchrotron radiation sources which was built is the European XFEL. A one billion Euro ‘free electron laser’, based on a superconducting accelerator technology and spread out 3km beneath the city of Hamburg. The produced x-ray pulses allow pictures, for example from proteins, with sub-atomic resolution and an exposure time short enough to enable in-situ studies of chemical reactions.
This talk aims to explain how particle accelerators and in particular light sources work, for what reason we need these big facilities to enable new types of science and why most of modern technology would be inconceivable without them.

Two of my favorites: code::dive conference 2014 - Scott Meyers: Cpu Caches and Why You Care: https://www.youtube.com/watch?v=WDIkqP4JbkE CppCon 2014: Mike Acton "Data-Oriented Design and C++": https://www.youtube.com/watch?v=rX0ItVEVjHc They're mostly about C++ and cache aware/data oriented programming.
The Mike Acton talk is really valuable to anyone interested in efficient software, and doesn't have so much C++ as to be a barrier: I found out about it from a Go developer.
They've done several iterations of this, including a censored/shorter version for DEFCON 22. This version is the best, with all details, no secrets withheld. I find the content rather stunning, and I've even watched it several times.
Another one would be "Let It Crash! The Erlang Approach to Building Reliable Services" by Brian Troutwine. [2]
I don't know if you would call it "technical" but Brett Slatkin's talk on Cohort Analysis is something anyone interested in tools to analyze how our users behave should watch. [3]

Very terse and content rich security walkthrough of corporate IT security fails by Joseph. I find delivery also highly entertaining.
