Deviant Ollam's two-hour conference talk explains how elevators work, from the pit and buffers to the car top, controller logic and access-control features. It shows how this knowledge can be used for optimization and for bypassing building security.

Kurzgesagt argues that Facebook's claimed 8 billion daily video views are inflated by freebooting, meaning re-uploads of creators' videos. It describes how this harms independent creators.

Locksport historian Schuyler Towne's RVASec 2012 talk on why people lock their doors, tracing the history of locks and the assumptions about security behind them.

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.

Theo de Raadt presents pledge, a new OpenBSD security mechanism that kills processes which exceed the system calls they declared they need. The talk was given late at night at Hackfest 2015.

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.

Destin Sandlin of Smarter Every Day explains 'Facebook freebooting', where Facebook users re-upload YouTubers' videos natively and the original creators lose views and revenue. He describes his own attempts to get Facebook to act.

John Oliver's Last Week Tonight segment on US voting machines, covering how they work, their security weaknesses, and how elections could be made more secure.

LockPickingLawyer picks an Amazon's Choice 'high security' padlock in about two seconds.

Rory McCune's AppSec EU 2015 talk on security risks in modern software deployment. It covers weaknesses in package ecosystems like npm, RubyGems and PyPI, and repository compromise.

Jonathan Blow's Reboot Develop 2017 talk on making game programming less terrible, discussing software bloat, slowness and the design goals behind his own programming language.

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.

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.

Maciej Ceglowski's talk at Web Directions argues that small teams and lone programmers can build sustainable businesses without chasing Silicon Valley's grow-or-die model. He offers alternative, more achievable definitions of success.

3Blue1Brown illustrates how enormous the 256-bit search space is, showing how infeasible it is to find a hash or key by guessing and checking.

A HOPE conference talk by Howard Payne and Deviant Ollam on common keys, such as elevator and fire service keys, that open many buildings. It covers physical security weaknesses from shared key standards.

David Heinemeier Hansson, creator of Ruby on Rails and partner at 37signals, argues that planning is guessing and startups should focus on today. He says constraints are an advantage and that startups can bootstrap profitably in sizable markets.

Netanel Rubin's 31C3 talk chains Perl's syntax quirks into a powerful remote code execution attack, taking down popular Perl-based projects.

Pieter Levels talks at Dojo Bali about building startups without venture capital through bootstrapping, persistence and learning many skills as a generalist. He reviews his own past projects.
