Deviant Ollam shows that most physical attacks on doors bypass the lock, with photo and video examples of how doors, frames and hardware get defeated. It is a physical security talk from Shakacon.

A DEF CON 20 talk by RenderMan on the security weaknesses of ADS-B, the unencrypted, unauthenticated aircraft tracking broadcast. It shows how easily the data can be spoofed and what that means for security designed in too late.

Jayson E. Street's DEF CON 19 talk shows photos from real security engagements where he was already inside client facilities, illustrating how social engineering and physical intrusion can cause huge losses. For each attack he also explains what defenses would have stopped him.

David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.

A UC Berkeley CS 161 lecture by Nicholas Weaver on cryptocurrency and blockchains, covering how they work and the case against them. It is aimed at a computer security course audience.

A 36C3 talk that systematically evaluates OpenBSD's exploit mitigations, asking how effective they really are and what they cost in performance, complexity and inspectability. It challenges the project's security marketing.

A short demo of Inferno, the Plan 9 descendant operating system, running on an Android phone as Hellaphone. It shows calls, SMS and data working. The video quality is rough because the camera was held in front of the screen.

CGP Grey explains the history of the US Social Security card and number, and why they became a de facto national ID despite never being meant for it. He also covers why America resists a proper identity card.

The Lock Picking Lawyer tests the supposedly unpickable lock designs built by the Stuff Made Here channel. He looks for bypasses and weaknesses in the novel anti-picking mechanisms.

A 36C3 talk by Bunnie Huang arguing that open source is necessary but not sufficient for trustworthy hardware, because verifying hardware is destructive and so creates a time-of-check/time-of-use gap. It surveys supply chain security and classes of hardware attacks, and presents the Betrusted approach to narrowing that gap.
