The original 2012 screencast introducing Meteor, a JavaScript framework for building web apps quickly. It demonstrates realtime updates, latency compensation and low boilerplate.

Stuart Marks explains the intended purpose and proper use of Java 8's Optional class and why it caused so much controversy. He gives guidelines for using its small API correctly.

Walter Bright explains to the Northwest C++ Users Group how the D programming language can interface directly with legacy C++ code. He covers why C++ is hard to interface with and how D approaches the problem.

Java Language Architect Brian Goetz talks at a Clojure conference about the challenges of evolving a mature language like Java while preserving compatibility with existing code and developer expectations. It also gives a look at where the platform is headed.

Brian Lonsdorf explains why Underscore.js falls short as a functional programming library, then introduces currying, composition and point-free style in JavaScript. He argues for data-last argument ordering.

Chris McCord's ElixirConf EU 2019 keynote introducing Phoenix LiveView, which builds interactive server-rendered apps without writing JavaScript. It explains how only changed dynamic parts are sent over a websocket.

A DEF CON 21 talk by Karl Koscher and Eric Butler on how SIM cards work, including Java Card applets, the SIM toolkit and the OS running on the card. It shows how much control the network and the card have independent of the phone.

Sebastian Markbage explains how React is moving toward a minimal API surface by leaning on language features and patterns instead of dedicated framework APIs. He also touches on JSX and syntax proposals for future JavaScript.

Ryan Dahl's JSConf EU talk introducing Node.js to the world. He explains the motivation for event-driven, non-blocking I/O, with JavaScript chosen mainly for its asynchronous nature.

Rafal Dittwald's Clojure/north talk shows how to move from writing Java-style code in Clojure to thinking in data-driven, functional terms. He walks through a JavaScript example, refactoring imperative code step by step into a functional core.

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.

A JSConf 2014 talk visually breaking down algorithms behind everyday UI patterns, such as dropdown menus that vanish when the mouse drifts and picking the nearest target to the cursor. It shows how these are implemented in JavaScript.

Derek Slager's Clojure/conj talk argues that ClojureScript is a pragmatic choice for web development. He addresses common objections, recent improvements, tooling and use cases where it shines.
