GoldenSound publishes music on Tidal to test MQA, a deep dive into the format's claims and problems including its leaky filter. Testing begins around the 5:45 mark.

Michael Bryzek of Flow gives a QCon London 2018 talk on key decisions for building maintainable microservices. It covers infrastructure, continuous deployment, communication, event streaming and language choice.

Greg Kroah-Hartman's Linaro keynote on contributing to the Linux kernel, explaining why maintainers prefer upstreamed code and how they view contributions.

Monty Montgomery of Xiph.org gives real-time demonstrations of sampling, quantization, bit depth and dither using real audio equipment, including both digital analysis tools and vintage analog bench gear. It shows that sampled audio is not stair-stepped and corrects common misconceptions about digital audio.

Ben Eater explains how VGA signals work and builds a breadboard circuit that produces correct sync timing so a monitor recognizes the signal. He then builds toward displaying an image from simple logic chips.

Techmoan's 45-minute retrospective on Sony's MiniDisc, covering the first and last machines, ATRAC, MD-LP, Net-MD and HiMD. It argues the format deserves more credit than its US failure narrative suggests.

Techmoan's beginner introduction to the compact cassette, testing metal tapes and Dolby S noise reduction on a Sony TC-S1 deck. He checks whether a cassette can sound close to a CD when good tape and equipment are used.

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.

Retro Game Mechanics Explained dissects how Atari's Quadrascan vector displays and vector generator hardware drew games like Asteroids and Tempest.

Musician and audio engineer Benn Jordan tries Dolby Atmos as a consumer, covering the theory of immersive audio, its business model, and home theater and headphone listening. He concludes it often falls short of the pitch.

Tech Ingredients shows how to build flat panel speakers from exciters and foam board, with construction guidelines, measured SPL comparisons and a complete system playing music.

Noodle explores how retro pixel art was designed for CRT displays and why games look different on LCDs, with input from pixel artists and CRT researchers.

A Google I/O 2013 talk by Android audio engineers on why reliable, low-latency audio is hard on the platform. It covers problem areas across the stack, platform work underway and techniques apps can use.

A tour of the historic WLW transmitter facility in Mason, Ohio, recorded at Hamvention 2013. It shows the surviving equipment from the 500,000 watt AM era, when WLW was the only US station at that power, and explains the history.

Benn Jordan's video about storing a PNG image in a living bird, a starling that learns to reproduce encoded sounds. It mixes ornithology, audio engineering, and data encoding.

Ben Eater finishes building a minimal VGA video card from logic circuits. He explains analog RGB signals, stores an image in an EEPROM and builds a simple digital-to-analog converter to display it.

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.

Dan Worrall explains when higher sample rates help in recording and mixing, and when they do not. He goes into oversampling versus higher sample rates, and aliasing in distortion plugins.

Technology Connections gives a deeply researched history of RCA's CED video disc system, a capacitance-based format that took over a decade to reach market. Part one covers its development and strange technology.

Tech Ingredients builds a pair of large Voigt speakers and explains ported, transmission line and horn designs. It tests them in an anechoic chamber and uses constrained layer damping for the enclosure.

Benn Jordan measures air quality around vinyl records with a pollution meter and finds high particulate and VOC levels. He argues vinyl should be modernized.

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.

Yaron Minsky of Jane Street shows how the OCaml Incremental library lets trading UIs express data transformations that are easy to read and efficient on streaming data. It includes a live table demo.

A recording of the TASBot block at Awesome Games Done Quick 2017, where a robot plays games via tool-assisted speedruns, including Super Mario 64 and Portal on an SNES via arbitrary code execution, and ending with a Twitch Plays segment. It showcases console exploits and creative hardware hacking.

A short film by Max Joseph about his anxiety in bookstores and how to read more books amid constant streaming, social media and news. He looks for ways to rebalance his content diet in favor of reading.

Netflix engineer Drew Gallatin explains why the company runs FreeBSD-current on its CDN. He describes the team, how they track upstream, their contributions and performance milestones, and a bug causing a 20% performance regression.
