Part 2 of the IROS 2011 keynote by Sebastian Thrun and Chris Urmson on Google's self-driving car. It shows how the car perceives its surroundings with a lidar point cloud and recognizes traffic lights and pedestrians. The audio is poor because it was recorded on a pocket camcorder.

Neuroscientist Anil Seth argues in this TED talk that perception is a controlled hallucination: the brain constantly predicts the world and our shared agreement is what we call reality. He also touches on the construction of the self.

Karen Sandler, then Executive Director of the GNOME Foundation, talks at OSCON 2011 about the risks of proprietary, closed-source software in implanted medical devices like her own pacemaker-defibrillator.

Chris Urmson, head of Google's self-driving car program, shows footage of how the car perceives the road and decides what to do. Examples include cyclist hand signals, school buses, police officers and complex intersections.

A short !!Con 2016 talk by blind developer Sina Bahram on how he uses a computer and writes code with a screen reader at about 1,000 words per minute. He plays how common interfaces sound and challenges the audience to go a day using only the keyboard.

Excerpts from Linus Torvalds's DebConf 14 talk on why desktop Linux struggles. He covers application distribution, distros breaking backwards compatibility, wasted package management effort and how Windows does app distribution better.

Skateboarding pioneer Rodney Mullen talks about how the open skate community and its environments drive the invention of new tricks out of pure passion. He draws parallels to collaboration and open source.

Tom Scott explains how he built his emoji keyboard, which turned out to be a series of bodged-together tools including AutoHotkey and LuaMacros. He tells stories about the value of quick-and-dirty solutions.

A ten-minute clip from Jonathan Blow's talk on preventing the collapse of civilization, arguing that software quality and the knowledge to build it are in decline.

Steve Yegge's OSCON Data 2011 talk imagines what you could do with Google-scale storage and compute a decade later. He argues smart people should work on hard problems such as biology rather than cat pictures, and the talk ends with a moment many took as him quitting Google.

Yegor Denisov-Blanch of Stanford presents a study of nearly 100,000 developers at hundreds of companies, measuring how AI affects productivity from commit data. It finds an average boost of about 20% with wide variance by codebase, task complexity and stack.

A clip from Tesla Autonomy Day 2019 where Elon Musk argues cameras are enough for self-driving and calls lidar a fool's errand.

Andrej Karpathy's Databricks talk on Software 2.0, the shift from human-written code to code produced by neural network training. It covers how developer work moves toward curating datasets, the advantages and challenges, and opportunities for new tooling.

Jim Keller, CTO of Tenstorrent, talks at Samsung Foundry's SAFE 2021 about building AI silicon through modular, provable design. The talk also touches on Tenstorrent's RISC-V Ascalon core.

Gary Wilson's TEDxGlasgow talk argues that internet pornography hyperstimulates the brain's reward system and can cause symptoms that reverse when people stop. TED notes that several claims are not supported by respected academic studies.

Luis von Ahn, creator of CAPTCHA and reCAPTCHA, explains how small contributions from many people online can digitize books. He then introduces Duolingo as a way to translate the web while people learn languages.

A short conference talk from !!Con 2017 in which Kevin Chen explains the HDR imaging algorithm from a foundational paper, framing it as a system of linear equations, and implements it in a Microsoft Excel spreadsheet. No prior image processing knowledge is needed.

A short edited excerpt of Terence McKenna arguing that culture acts as an operating system for the mind, set to imagery and music. It touches on psychedelics and how they change thinking.

Moral philosopher James Flynn explains the Flynn effect, the steady rise of IQ scores across the 20th century. He argues the shift reflects a move toward abstract, hypothetical thinking as cognitively demanding professions grew.

Richard Stallman's TEDxGeneva 2014 talk describing how nonfree programs give companies control over users and what users can do to regain control. It introduces the free software movement and the four freedoms.

Nina Paley's TEDxMaastricht talk arguing against copyright and for copyleft and free culture. She argues that restricting ideas harms creativity and that culture belongs to everyone.

Luis von Ahn, creator of CAPTCHA and reCAPTCHA, presents Duolingo at TEDxCMU 2011. The idea is to have millions of people translate the web for free while learning a language, an example of human computation.

Psychiatrist Daniel Amen discusses lessons from 83,000 brain scans, arguing that brain activity patterns relate to psychological symptoms and that you can improve your brain.

A clip in which Eben Moglen tells how he grew up when software was freer and how his path crossed Richard Stallman's. He describes how they came to work together to make software free again.

Psychology professor Lisa Feldman Barrett presents her research on what emotions are, arguing that the brain constructs them rather than reading them off faces. She says this means we have more control over our emotions than we think.

Ramesh Raskar presents femto-photography, a technique that captures a trillion frames per second, fast enough to show light itself moving through a scene. He discusses possible uses such as cameras that see around corners or inside the body.

Inventor Mary Lou Jepsen demonstrates using red light and sound to see inside the body and brain, aiming at tumor detection and neural activity measurement, and potentially a cheaper wearable MRI replacement.

Eben Moglen's 2011 Personal Democracy Forum talk on the loss of anonymity and privacy on the internet. He proposes building an alternative net of personal servers, the idea behind FreedomBox.
