Kaze Emanuar explains how he rewrote and optimized the Super Mario 64 source code so it runs far faster on real N64 hardware. He covers performance bottlenecks and fixes in detail for his ROM hacks.

ScienceClic explains why the rubber sheet analogy for general relativity is misleading and offers a new visualization that includes the curvature of time and shows gravity as motion through curved spacetime.

A short !!Con 2016 talk by blind developer Sina Bahram on how he uses a computer and writes code with a screen reader at about 1,000 words per minute. He plays how common interfaces sound and challenges the audience to go a day using only the keyboard.

An animated visualization of basic quantum mechanics using a free particle, with simulations based on the actual equations. It covers waves, particles, and how measurement collapses the wavefunction.

Numberphile's Dr James Grime explains the flaw in the Enigma machine, namely that a letter could never be encrypted to itself, and how that helped the Allies break the code. It touches on the Bombe and Alan Turing.

The final codec conversation from Metal Gear Solid 2, in which the AI 'Colonel' explains that the Patriots filter out junk information and curate truth for humanity. It plays as a dark meditation on information overload, manipulation and shared reality.

A fan-made Metal Gear Solid 2 codec call using AI voice synthesis, in which the Colonel warns Raiden about using AI to censor the internet and enforce digital ID. It riffs on the game's 'Selection for Societal Sanity' conversation.

Avi Bryant demos Dabble DB, a web-based spreadsheet-like database for building apps without code. It shows how users can model and relate data through a smooth interface.

The first of an eight-part ScienceClic series building general relativity, covering worldlines, proper time and coordinate systems with animated visualizations.

A reverse engineer walks through fixing a ten-year-old bug in Guitar Hero III without access to its source code, using a disassembler and decompiler. It is technical but explained step by step.

Roy Beck's short gumball presentation using World Bank and Census data to argue that letting people immigrate to the US cannot solve world poverty because the numbers are so large. It is made by NumbersUSA, an immigration-restriction advocacy group.

A short Ericsson film demoing Erlang, showing concurrent processes, debugging tools, and hot code reloading, including crashing parts of a running system while calls continue.

A visualization and sonification of 15 sorting algorithms, from selection sort to bogo sort, run on shuffled integers in six minutes. Each algorithm gets a size and speed scaled to its complexity.

Milton Friedman explains why the US tax code is enormously complex and why meaningful reform is unlikely. He argues that politicians profit from the complexity, since tax breaks are products they sell and the code works as a tool of reward and punishment. The clip is about 14 minutes from his lecture series.

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.

Bach's Toccata and Fugue in D minor on organ, shown with a Music Animation Machine bar-graph score instead of traditional notation.

An artist describes discovering she has aphantasia, the inability to form mental images, and how it affects her work. She asks viewers about their own visualization.

A short film about the Erlang language, showing telecom systems built from lightweight processes and demonstrating hot code swapping. It is an edited version of the original Ericsson video.

Isao Hashimoto's time-lapse map shows all 2053 nuclear explosions between 1945 and 1998, with each nation getting a blip and a running tally. Each second represents one month.

ScienceClic gives a 15-minute animated introduction to quantum field theory, covering fields, spin, conserved quantities, the standard model and interactions.

A Two Minute Papers episode on NVIDIA's recurrent denoising autoencoder, which cleans up noisy Monte Carlo path-traced image sequences. It shows how a neural network can produce usable renders from very few samples.

About Here explains how North American building codes requiring two staircases make small multi-story apartment buildings hard to build, and contrasts this with places that allow single-stair designs.

Anna Rosling Rönnlund presents Dollar Street, a project photographing homes in dozens of countries, from stoves to beds to toilets, and sorting them by income. She shows how data visualization can change how we see the world.
