Elias Martenson presents his Emacs-based workflow for building a web application (the Potato chat platform) with Common Lisp on the backend and ClojureScript on the frontend. He demonstrates SLIME, Paredit, CIDER and debugger-driven interactive development. The talk is 79 minutes and was given at Emacs SG.

Ahmon Dancy of Franz Inc explains low-level programming in Common Lisp, including off-heap data structures used in AllegroGraph to manage memory outside the garbage collector.

Linus Tech Tips tests a large batch of DisplayPort cables with a Total Phase cable tester, checking bandwidth and signal quality. Many cables did not meet their claimed specs.

A five-minute demo of the Common Lisp debugger fixing a bug, recompiling a single function, and resuming execution from the failed stack frame. It shows how to avoid re-running long computations.

Christian Schafmeister presents lessons from six years of implementing Clasp, a Common Lisp compiler using LLVM as its backend that interoperates with C++. He explains handling a dynamic, memory-managed language on LLVM.

Shaun Lebron surveys 50 years of Lisp editing history and forgotten innovations in structural editing. He argues future Clojure editors could learn from them, and covers ideas like Parinfer.

Charbax interviews the CEO and CMO of CLEARink at SID Display Week 2019 about their eTIR reflective display technology. It demos 9.7-inch low-power color and video ePaper with high refresh capability.

Stefan Karpinski's European Lisp Symposium 2016 talk asks whether Julia is a Lisp. He covers the features it borrows from Lisp, such as macros and closures, and where it departs, including syntax and its type system, with generated machine code shown.

The first lecture of MIT's 6.001 (SICP) with Abelson and Sussman, giving an overview of the course and an introduction to Lisp. It argues that computer science is about managing complexity and abstraction, not computers.

Aditya Siram introduces Shen, a small hosted Lisp with macros, a built-in Prolog and an optional type system. The talk demos a full web app moving between functional, logic and imperative styles, including turning JSON into a type with macros.

Timothy Baldridge presents Pixie, a lightweight Lisp built on RPython, at Strange Loop 2015. It covers C interop, immutable data structures, fast startup and async-by-default IO.

A SIGGRAPH 2013 demo from Douglas Lanman and NVIDIA of near-eye light field displays, which allow much thinner head-mounted displays that still show accurate focus and depth cues.

Christian Schafmeister presents CANDO at the 2016 European Lisp Symposium. It is a compiled Lisp-based language for designing macromolecules and nanoscale materials, built on the Clasp implementation of Common Lisp.

A short demo of SEdit, the structure editor for Interlisp-D on Xerox Lisp machines in the 1980s, which edits code as trees rather than text.

HDTVTest reviews the Apple Pro Display XDR using measurements and a side-by-side comparison with a Sony BVM-HX310 dual-layer LCD reference monitor. It examines how well the display handles HDR against a professional reference.

William Byrd presents at Papers We Love NYC on what he calls the most beautiful program ever written, a Lisp interpreter written in Lisp. He walks through the metacircular interpreter and related ideas, and demos relational programming and program synthesis near the end.

Peter Thiel's lecture from the How to Start a Startup course on business strategy and monopoly theory, arguing that competition destroys profits and that startups should aim to build monopolies. It covers the ideas of Zero to One.

Ben Krasnow of Applied Science explains how electrophoretic e-paper displays work and how he modified the driver firmware and waveform lookup tables of a 4.2-inch panel to reach roughly 3Hz partial refresh. It covers the tweakable constants in the refresh process and touches on colored e-ink microcapsules.

A demo of the Symbolics Graphics Division's S-Packages, a Lisp-based 3D color graphics and animation system from the 1980s. It was later used in developing for the Nintendo 64.

Veritasium visits the Micromouse competition, where small autonomous robots race to solve mazes at extreme speed. It covers the competition's technical history, including fans and ground effect enabling very high-g turns.

Johnny Lee demonstrates head tracking with a Wii remote and a head-mounted pair of IR LEDs, so a screen acts like a window into a 3D scene as your head moves.

A silent PLOS ONE video of New Caledonian crows solving Aesop's Fable puzzles by dropping objects to raise water and reach food. It shows example trials from experiments testing causal understanding of water displacement.

Jeff Geerling looks at a Sharp NEC commercial display with a slot for a Raspberry Pi Compute Module. It is a large screen without built-in smart TV features or tracking.

Marco Baringer's tutorial video on SLIME, the Emacs mode for developing Common Lisp. It demonstrates the interactive workflow of working against a live Lisp image.

Kalman Reti, one of the last Symbolics developers, gives a roughly hour-long talk on Symbolics Lisp machines. It covers the machines and their environment from an insider's perspective.
