Philosopher Dan Dennett argues in a TED talk that we do not understand our own consciousness and that our brains often fool us. He uses perceptual examples, including a painting that invites the viewer to fill in detail.

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.

A short clip of Neil deGrasse Tyson answering a question about why there are not more women in science. He describes the resistance he faced as a Black kid pursuing science and the systemic barriers many people encounter.

Greg Young, who coined CQRS, gives an in-depth GOTO 2014 talk on what event sourcing is, when it is valuable and when it is not, along with its trade-offs and common misconceptions.

Greg Young, who coined CQRS, looks back on a decade of domain-driven design, CQRS and event sourcing at DDD Europe 2016. He discusses where event sourcing applies and how simple its core can be.

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.

Developmental and synthetic biologist Michael Levin speaks at a Harvard Extension student event on bioelectricity, body intelligence and regenerative medicine. He discusses how cell electrical networks guide growth and form.

Alen Ladavac of Croteam talks about continuous integration and automated testing pipelines in games, with case studies from The Talos Principle and Serious Sam.

Jean-Marc Jancovici gives an MIT Media Lab talk on whether technology can save us from climate change. He argues from a physical view of energy that economic growth, energy use and climate impact are tightly linked.

Rich Hickey's keynote at RailsConf 2012, a close sibling of his 'Simple Made Easy' talk. He distinguishes simple (not intertwined) from easy (familiar), and argues that software complexity comes from complecting things, with Rails-specific examples including large gem collections.

Bryan Cantrill's Monktoberfest 2017 talk on leadership and organizational principles, ranging from the Gettysburg Address to Uber and Amazon. He argues for the difference between principles and values and criticizes vague corporate principles.

Alan Kay's 2015 talk on the power of simplicity, arguing that systems become simpler by building on more sophisticated fundamental building blocks and that big research horizons drove invention at Xerox PARC. It ranges across computing, tools and scaling software.

A DEF CON 26 talk by investigative journalists and hackers on the fake science industry, with bogus conferences and predatory journals that give studies false credibility. It draws on a large investigation into the money behind them.

Technosociologist Zeynep Tufekci argues that the machine-learning systems used to serve ads also decide what political and social information people see. She explains how opaque algorithms can nudge, segment and manipulate users, and warns that the real danger is powerful people using AI to control populations.

Dr. Richard Cook, a physician and patient safety researcher, presents his ideas on how complex systems fail, at Velocity 2012. He argues for designing for resiliency rather than trying to exhaustively handle every failure mode.

A full-day recording of the University of Utah computer science department's 50th anniversary event with panels, keynotes and talks by alumni and pioneers. It includes Ivan Sutherland's presentation on single flux quantum electronics.

Roman Mars gives a funny TED talk on vexillology, laying out five basic principles of good flag design and why many city flags fail them.

Bret Victor's talk "Inventing on Principle" argues that creators should find a guiding principle to fight for. He shows demos of immediate-feedback tools, such as live-updating code and animation editors.

A four-minute Velocity 2011 talk in which Artur Bergman, then at Wikia, argues bluntly and with profanity that SSDs should replace spinning disks in servers.

Richard Wilkinson presents data showing that societies with larger income gaps do worse on health, lifespan, trust and other measures. He argues the effects track inequality itself rather than average income. It is a 17-minute TED talk.

Amazon's Jon Jenkins at Velocity 2011 on how operations can drive revenue and on Amazon's highly available, autonomous architectures. It includes details on deployment frequency and Amazon's move to AWS.

Berkeley neuroscientist Jack Gallant shows how fMRI brain mapping can be used to decode what a person sees, with visualizations of brain activity and its implications.

Robert C. Martin (Uncle Bob) gives a talk on the SOLID principles of object-oriented and agile design, in the context of encapsulation and clean code.

A panel from the Beneficial AI 2017 conference moderated by Max Tegmark, with Elon Musk, Stuart Russell, Kurzweil, Hassabis, Harris, Bostrom, Chalmers and others. They discuss likely outcomes of human-level AGI and what outcomes are desirable.

Edward Kmett's 2013 talk at Prezi in Budapest on succinct data structures, which store data in close to the information-theoretic minimum space while supporting fast queries. It ties together the research and walks through his Haskell succinct library.

A 2007 Google Tech Talk introducing Polyworld, an artificial life simulator used to evolve artificial intelligence by designing worlds rather than minds. It presents results from ongoing attempts to evolve intelligent behavior.

Michael Levin's NeurIPS 2018 talk on bioelectric computation outside the nervous system, showing how cell electrical networks shape development and regeneration. It covers morphological information processing in living tissue.

Matt Kulukundis explains how Google designed SwissTable, a fast, cache-friendly hash table, step by step from std::unordered_map. The talk covers open addressing, SIMD probing and the tradeoffs of changing a fundamental data structure.

Joel Grus's JupyterCon talk explaining why he dislikes Jupyter notebooks. He covers hidden state, trouble with reproducibility and testing, and how notebooks frustrate teaching. He shows his preferred workflow and what Jupyter could change.

Sociologist and comedian Harald Eia argues in a TEDxOslo talk that Nordic social democracies produce more rich people per capita than the US or UK. He credits high taxes, welfare and strong unions for creating a safety net that enables risk taking.
