Fernando Rojo explains how BeatGig reached $10M in sales with one frontend engineer by sharing code between React Native and Next.js, covering navigation, animation, theming and performance.

Cheng Lou's react-europe 2016 talk lays out a mental framework for thinking about abstraction levels in JavaScript tooling, from Angular and Grunt to Webpack and React. It uses that framework to reason about the cost of abstractions and how to choose between competing solutions.

Kirk Sorensen's Google Tech Talk on thorium molten-salt reactors (LFTR). He covers why the technology was shelved after early development and argues that now is the right time to revisit it.

Kirk Sorensen's Google Tech Talk on liquid-fluoride thorium reactors, a design that could burn nuclear waste and use thorium as fuel. It draws on Oak Ridge National Laboratory work from the 1950s and 60s.

A five-minute lightning talk from React.js Conf 2016 by Elie Rotenberg on protecting the DOM from tampering. It shows how React tree obfuscation (react-armor) can shuffle class names, tags and tree structure to defeat CSS-selector-based ad blocking.

An episode of REACT in which children try to figure out 1970s-1980s computers, including an Apple II and floppy disks. It was made to promote the AMC show Halt and Catch Fire.

Jafar Husain's ACM keynote presents Netflix's JSON Graph and Falcor, which let web developers treat all cloud data as one virtual JSON model. It combines reactive programming with REST principles.
