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.

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.

Martin Kleppmann argues that databases are global shared mutable state and proposes treating them as an ever-growing log of immutable facts. Derived data such as caches, indexes and views is then built by stream processors like Apache Samza. The talk draws on Kafka and LinkedIn's experience with commit logs.

A 38C3 talk on how advanced chips are made, centered on EUV lithography and the global supply chain behind it. It covers technical challenges from raw materials to finished chips and the geopolitical weight of semiconductors.

Hans Rosling's TED@Cannes talk uses boxes and animated data graphics to show how world population will grow to about 9 billion. He argues that raising living standards for the poorest is what reduces population growth.

Cindy Gallop gives a 4-minute TED2009 talk arguing hardcore pornography has distorted how young men think about sex. She introduces her website MakeLoveNotPorn as a response.

React Helsinki meetup recording featuring a talk on lessons with Apollo GraphQL and Linear co-founder Tuomas Artman on real-time sync for web apps. The sync talk explains Linear's local-first architecture.
