DEFCON 14: DNS Abuse Infrastructure and Games
Speaker: Gadi Evron Abstract: DNS operations today are no longer just a secure configuration and bandwidth, but rather a whole world of online abuse and criminal activities. In this presentation we will discuss how DNS has become this infrastructure for online crime and abuse. Spam, DDoS

Special Relativity | Lecture 7
(May 21, 2012) Leonard Susskind reviews some of the heavy mathematics from the previous lecture and discusses how at times complicated mathematics is the only way to explain high level physics, briefly sharing his thoughts on how and where math and nature collide. In 1905, while only twen

Maxwell's Equations in Tensor Form
It is a critical prerequisite of QED to understand how the laws of electromagnetism are encoded in tensor form. In this Lesson we build the 4-potential and then create the electromagnetic field tensor. Then we develop the 4-current and then combine everything into an arguably more elegant

[Lesson 22] QED Prerequisites: The Electromagnetic Field Tensor
This is a REPOST of a lecture with video repairs and some annoying errors corrected! To reinforce our efforts to put the 4-potential at center stage we do a second development, this time founded in Lorentz invariance ala Landau and Lifshitz "Classical Theory of Fields." Then, we show how
