ceramic module

Dave Jones of EEVblog tears down a 1991 IBM 9121 thermal conduction module from a System/390 mainframe, a 63-layer ceramic hybrid module with 2772 pins worth about $250,000, and demonstrates a BGA desoldering technique.

GreatScott! tests ProLogium lithium ceramic batteries, a solid-state design. He measures their volumetric and gravimetric energy density, compares them to Li-ion and LiPo, and runs durability tests at the end.

John Ousterhout, Stanford professor and creator of Tcl, presents the ideas of his book A Philosophy of Software Design in a Talks at Google session. He covers managing complexity, deep modules and interfaces, and what he teaches in his Stanford software design course.

A short screencast tour of JSPM, SystemJS and ES6 features, building a small app with the then-new JavaScript module and package tooling. It shows how JSPM works as a package manager, bundler and loader.

Node.js creator Ryan Dahl discusses ten design mistakes he made in Node, including package.json, npm, and module resolution. The talk sets out the motivations behind his later project, Deno.

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.

Jack Diederich's PyCon 2012 talk argues that classes are overused in Python and walks through real code, refactoring away unnecessary classes, exceptions and modules. It popularized the heuristic that a class with two methods, one being __init__, should be a function.

Joe Armstrong, co-inventor of Erlang, gives a funny and opinionated Strange Loop talk on the tangled state of software: build tools, package managers, entropy and the physical limits of computation. He argues for ideas like naming things by content hash and throwing away your first version.

Ahoy's documentary traces tracker music from early Amiga software like SoundMonitor and Soundtracker through the demoscene, Protracker, and PC trackers such as Screamtracker and FastTracker. It covers the sound, culture and history of 16-bit module music.

An Autoline After Hours episode with teardown expert Sandy Munro and a panel of auto journalists. It covers his Tesla Model 3 teardown, including the battery, drive modules, build quality and manufacturing automation.

Adam Savage shows a set of Mitutoyo ceramic gauge blocks and uses them to explain metrology, the science of measurement. He argues that accuracy and precision work differently than most people assume, which changes how you think about every measuring tool.

Zack Freedman introduces Gridfinity, his free, open-source modular workshop storage system of 3D-printable bins and baseplates. The video walks through the design, the parametric templates and the many module types that fit parts, tools and accessories.

Edward Kmett speaks at the Boston Haskell meetup about type classes and the design tradeoffs of global coherence compared with other approaches to implicit instances. It covers why uniqueness of instances matters for reasoning and refactoring.

Raymond Hettinger explains Python's dataclasses module, showing the problem it solves and its key design decisions. He places it in a progression from tuples and dicts through named tuples and attrs.

In her final days as ISS commander, Sunita Williams gives an extensive tour of the station's modules and research facilities, narrating the work done aboard.

Clickspring makes the pin-and-slot epicyclic gearing of the Antikythera Mechanism, the module modelling the Moon's variable motion in the Greek theory, by hand.

Big Clive tears down a smart meter with a wireless modem found among fly-tipped materials. He examines its internals and checks conspiracy claims about microphones, cameras and 5G.

A 1991 Amiga tracker module, 'Space Debris' by Captain (Markus Kaarlonen), uploaded as a video of the music. It is a well-known piece of demoscene-era computer music.
