steel

America's Test Kitchen tests eight carbon-steel skillets to find the best one, asking whether a single pan can replace stainless, cast iron and nonstick. It names a winner and covers how the pans perform.

Guy Steele's 1998 OOPSLA keynote on designing a programming language that its users can grow. He builds the talk using only one-syllable words and terms he has defined, to demonstrate the idea.

Guy Steele's invited talk at Clojure/conj on the informal metanotation computer scientists use in papers to describe languages. He traces how this notation developed and why it is often unspecified and arcane.

Guy Steele presents a small geometric problem and compares four computational approaches: a classic sequential solution and three parallel-friendly ones. Each is illustrated pictorially and with working code, weighing total work against time to solution.

Guy Steele's Strange Loop 2010 talk argues that programmers should not have to think about parallelism, and that languages should support algorithms built on independence and divide-and-conquer. He also recounts fitting a program onto a single punch card.

Guy Steele's JuliaCon 2016 keynote on the Fortress language, its features and the lessons learned from the project.

A short video from a blacksmith, who heats and bends steel to rebut the claim that jet fuel could not weaken the steel in the World Trade Center. It is delivered with a lot of attitude.

Guy Steele's PPoPP 2017 keynote surveying the history of computer science metanotation, including BNF, inference rules, and overline notation. He argues the field's notations are inconsistent and fragmented.

CGP Grey explains why European diseases devastated the Americas while few deadly diseases traveled the other way. He ties it to livestock domestication, dense cities, and the ideas of Guns, Germs and Steel.

A two-minute Rouxbe cooking-school demo of how to heat a pan properly before cooking. It uses the Leidenfrost effect, where water beads and skates across a hot pan, to show when a stainless steel pan is ready.

A 2001 panel with Paul Graham, John Maeda, Jonathan Rees and Guy Steele on programming language design, part of the Dynamic Languages Wizards Series.

Guy Steele's classic 1998 OOPSLA keynote on how a programming language must grow with its user community. He delivers it in a playful style, starting with only monosyllabic words and defining new terms as he goes.

Clayton Christensen explains disruptive innovation using the steel industry, showing how mini-mills beat incumbents from the low end. He argues disruption is not about stupid or bad management.

Scott Manley explains the Cold War experiments in which steel and aluminium spheres, known as Lew Allen's Balls, were placed near nuclear detonations. The spheres survived the fireball, and he walks through what the declassified results show.

Jay Leno drives the Tesla Cybertruck with Elon Musk, who talks about the design, including the stainless steel body and bulletproof doors, and Leno demos the roll-up bed cover.

A performance of Bach's Coffee Cantata (BWV 211) conducted by Ton Koopman, with English subtitles. It is a comic secular cantata about a father and his coffee-loving daughter.

Mark Rober makes a plant-based burger for Bill Gates and explains why meat production strains the environment. Gates also appears and discusses his worry about steel and cement.

A short, nearly wordless demonstration of making sourdough pizza at home using a cast iron pan and the oven. It shows a Neapolitan-style result without a pizza steel or stone.

Clayton Christensen explains his theory of disruptive innovation at Oxford's Said Business School, using examples from steel, Toyota, Sony, Walmart and Godrej. He applies the theory to why some economies stagnate and others grow.
