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.

A short project video in which Greg Raiz turns a 32-inch eInk display into a wireless digital newspaper showing daily front pages. It runs for months on battery, and the code is published on GitHub.

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.

Jared Mauch tells how he got fed up with poor internet options in rural Michigan and built his own fiber network to his town. The talk was given at NLNOG Live in September 2020.

Ben Krasnow of Applied Science builds and operates a simple mass spectrometer, using it to measure potassium isotopes in a salt substitute. He explains the design choices and the theory behind it.

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.

This Old House's Ross Trethewey explains MERV filter ratings and how air filtration works, then shows how to build a localized DIY air filter, including a box fan with multiple filters.

Tech Ingredients shows how to build cheap, high-performance flat-panel speakers using audio exciters on sheet materials such as foam-core board. It explains how distributed-mode speakers work and walks through experiments to find good designs.

Ben Krasnow shows the first image from his home-built scanning electron microscope, after months of work, and walks through how the parts operate together.

A hobbyist builds a prototype full-frame CCD camera from scratch, with open-source design files and a custom PCB. The video shows the first, still rough prototype.

Ben Krasnow of Applied Science builds a DIY microbalance from an analog panel meter with an optical servo loop. It reaches about 5 micrograms of precision and is used to weigh a single eyelash at around 35 micrograms.

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.

Applied Science builds a replica Apollo DSKY using an electroluminescent driver circuit and screen-printed conductive ink, with source and PCB files published.

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.

Essential Craftsman follows up on his earlier video about a DIY approach to sleep apnea. It centers on forcing nose breathing during sleep with mouth taping and nasal strips, and says to seek medical guidance.

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.

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.
