food processing

Psychologist Melanie Joy's TEDxMunchen talk introduces carnism, the invisible belief system that conditions people to eat some animals but not others, and how it shapes reactions to food choices.

A UCTV panel with endocrinologist Robert Lustig, dentist Cristen Kearns and health policy expert Laura Schmidt on how the US food system and sugar industry influence diet and health, including industry efforts to shape the science.

Dr. Michael Greger presents his book How Not to Die at Google NYC, arguing that diet and lifestyle changes can prevent or reverse many of the top causes of death. He walks through evidence on whole-food plant-based eating.

Soil microbiologist Elaine Ingham speaks at the Oxford Real Farming Conference on how soil organisms cycle nutrients, unlock minerals from rock and air, and why pesticides and fertilizers harm soil life. Slides are linked in the description.

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.

Andrew Adams, a Halide developer, presents the Halide language for image processing and tensor computation. The talk explains the separation of algorithm from schedule with illustrated examples of parallelism, locality and redundancy tradeoffs.

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.

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.

Jim Keller's talk at the 2020 Scaled Machine Learning conference on Moore's Law in the age of AI chips. He compares scalar, vector and GPU-style parallel approaches to computation.

Dr. John McDougall argues at TEDxFremont that starch-based diets are what humans were born to eat, drawing on 40 years of nutrition and disease work.

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.

Seymour Cray's only surviving recorded talk, introducing the Cray-1 supercomputer in 1976. He describes the machine's design, including its vector architecture and cooling through the frame.

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.

Rick Houlihan's AWS re:Invent 2018 deep dive on advanced DynamoDB design patterns. It covers index overloading, GSI sharding, composite keys, graph processing and transactions.

Allan Savory's TED talk arguing that desertification of grasslands can be reversed with holistic managed grazing, which he says would also help reverse climate change. TED notes that other scientists have challenged his claims.

Dr. Jason Fung, a nephrologist, presents his view of the causes of obesity and type 2 diabetes, focusing on hormones such as insulin rather than calories alone. The talk draws on research and his Intensive Dietary Management program.

Bret Victor's 2013 MIT Media Lab talk argues that the media we think with determine which thoughts are possible. He demos new representations for scientific papers, circuits, filters and signal processing.

A presentation by Janice Stanger arguing that protein is overhyped and that excess or the wrong kinds of protein are harmful. It promotes a whole-foods, plant-based diet.

Thai farmer Jon Jandai talks about leaving Bangkok to farm and build his own house, arguing that food, shelter, clothing and medicine are easy to provide and that modern life is made needlessly complicated. He founded the Pun Pun Center for Self-reliance.

Joscha Bach's 31c3 talk argues that the mind should be understood as an information-processing system and that even the physical universe can be seen as computational. It tours the philosophy underlying artificial intelligence and cognitive science.

Peter Zeihan speaks at Iowa Swine Day 2022 on geopolitics, the end of globalization and agriculture. He argues that supply chains, energy and farm inputs are all about to be disrupted.

Prof. Eran Segal's TEDx talk on research showing that people's blood sugar responses to identical foods vary widely. It describes an algorithm that predicts individual responses and why one best diet for everyone does not exist.

An AWS re:Invent 2019 session for advanced DynamoDB users on design patterns used by large customers, including Amazon retail. It covers GSI sharding, index overloading, graph processing, composite keys and transactional workflows.

William Li presents anti-angiogenesis, the idea of cutting off the blood supply that feeds tumors, and argues that certain foods can help do this. It is a TED-Ed version of his TED talk.

Merlin Mann's 2007 Google Tech Talk on Inbox Zero, covering Getting Things Done, why an empty inbox matters, and strategies for handling high-volume email. It is a talk on attention and processing mail rather than on emptying it for its own sake.
