Liz Rice builds a container from scratch in about 100 lines of Go, showing that a container is not a lightweight VM but a set of Linux kernel features and flags.

2swap explains how he solved the Klotski sliding-block puzzle by mapping its full state space as a graph and visualizing it. The video includes footage of the Guinness world-record solve and links to an interactive graph.

SciPy 2015 talk by Nathaniel Smith and Stefan van der Walt on choosing a new default colormap for Matplotlib. It covers why Jet misleads, how perceptual color spaces work, and how viridis was designed.

Raymond Hettinger's PyCon 2013 talk on transforming code into idiomatic Python through a series of before-and-after refactorings. It shows how to use iterators, dictionaries, named tuples and other language features well.

CGP Grey argues that your brain treats a whole home as one room during lockdown, blurring work, rest and leisure. He recommends creating separate spaces and routines for different activities to stay balanced.

Joseph White, creator of PICO-8, retraces the design of the fantasy console and how tools can shape and guide creative work. He discusses cozy, constrained design spaces and the influence of user-made cartridges.

Lecture 1 of Harvard's Statistics 110 with Joe Blitzstein, introducing sample spaces, the naive definition of probability, counting, binomial coefficients and the sampling table.

James Howard Kunstler's TED talk argues that American public spaces and architecture have become unworthy of care, damaging civic life. He presents suburban sprawl and car-first design as failures of the common good.

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.

Josh Wardle, later the creator of Wordle, talks at SF Tech Poetics about why April Fools' Day in Silicon Valley is often lame. He shares lessons from building The Button and Place at Reddit.

A one-minute clip from Tom Sachs's Ten Bullets series on the rule "Always Be Knolling", which means constantly arranging and putting away unused objects.

A TEDxBangalore talk by The Ugly Indian, an anonymous collective, asking why Indians tolerate filthy public spaces. It describes their volunteer approach of quietly cleaning up spots and turning the tragedy of the commons into a victory.

Adam Savage and engineer Kipp Bradford build a compact wearable refrigeration system to keep Adam cool under costumes, modeled on the cooling unit in a NASA spacesuit simulator. It is a long, hands-on build session.

A very short demo of SmackBook, a hack that used the MacBook Pro's sudden motion sensor so that smacking the sides of the laptop switches desktop spaces.

A short explainer from 2swap on the chaotic behavior of double pendulums. It examines how predictable the system is for some starting conditions and whether closed-form solutions exist.

A clip from the movie Minority Report showing personalized advertising that recognizes a person as they walk through a mall.

Henry Segerman and collaborators demonstrate virtual reality experiences in non-Euclidean spaces, including hyperbolic and mixed hyperbolic-Euclidean geometry. The browser-based demos let viewers move through these spaces and show how strange the geometry feels from inside.
