A PyCon 2012 talk by early YouTube engineer Mike Solomon on how YouTube scaled its architecture, which is mostly Python.

Numberphile visits YouTube to learn why view counts on new videos used to freeze at 301. It explains that YouTube holds counts while it verifies views aren't from bots or fakes.

The Original Ace shows how creators can use a third-party music distributor to file Content ID claims on their own videos, turning false-claim abuse into a share of ad revenue. It also names distribution companies and their revenue splits.

Musician TheFatRat describes how his video with 47 million views was claimed by another party through YouTube's copyright system and how he got it back.

MinutePhysics explains Shor's algorithm, showing how a quantum computer factors large integers by finding the period of a number modulo N. It walks through the modular arithmetic and number theory that give the exponential speedup over classical factoring, and why this threatens encryption.

PBS Infinite Series explains how Shor's algorithm lets a quantum computer break RSA encryption, building on earlier episodes about cryptography and the math of quantum computers. It works through the idea step by step.

Glenn Vanderburg presents Cló, a Clojure library that reimplements TeX's core typesetting algorithms as composable functions. He shows what translating procedural, literate-programming code into functional form teaches.

A short CGP Grey bonus video explaining the shortest-splitline algorithm, which draws electoral districts by repeatedly splitting a state along its shortest dividing line while balancing population. It is offered as a neutral, algorithmic fix for gerrymandering.

Andrei Alexandrescu's CppCon 2019 talk revisits sorting, showing how branchless tricks, hybrid strategies and a cost metric can speed up std::sort-style algorithms on modern hardware.

Tom Scott-style absurdist tour by Tom7 of SIGBOVIK chess projects: a tournament of 30 weird chess algorithms used to rate a color- and piece-blind chess program. Topics include mirrors, arithmetic encoding, perverted game tree search and a diluted Stockfish.

Technosociologist Zeynep Tufekci argues that the machine-learning systems used to serve ads also decide what political and social information people see. She explains how opaque algorithms can nudge, segment and manipulate users, and warns that the real danger is powerful people using AI to control populations.

Hungarian folk dancers from Sapientia University act out the quicksort algorithm step by step, with music. It is part of the AlgoRythmics series of sorting algorithms performed as dance.

Psychologist Robert Epstein presents a Stanford EE380 colloquium on how internet algorithms such as search rankings can manipulate opinions, purchases and votes at massive scale. He also describes a new monitoring system for tracking such influence.

Lex Fridman interviews Donald Knuth about algorithms, complexity, The Art of Computer Programming, and his work habits. The conversation covers his approach to verifying algorithms and how he organises his time.

Tom Scott explains YouTube's 11-character video IDs, which are base-64 encoded 64-bit numbers, and whether YouTube could ever run out of them. It covers counting systems and base 64 briefly.

An ETH Zurich lab demonstration of a failsafe algorithm that lets a quadrocopter detect the loss of a propeller and recover, returning to its original position.

A mashup that plays a Miles Davis improvisation video alongside an LCD Soundsystem clip with no editing, so the two seem to perform together. It also became known for an affectionate mouse cursor moving along.

Tom Scott explains why confetti and snow wreck video quality, using interframe compression and bitrate. He demonstrates it live by changing the quality on screen.

A Jimquisition episode by Jim Sterling demonstrating the Copyright Deadlock, where a video includes footage owned by several companies so that competing YouTube Content ID claims cancel each other out. It highlights how absurd the system is.

A three-minute capture of SORTDEMO.BAS, the sorting visualization that shipped with QBasic. It animates insertion, bubble, heap, exchange, shell and quick sort with chiptune-like sound.

Folding Ideas uses the rise and fall of the YouTube competitor VidMe to examine why platforms are not friends to creators. It argues that alternatives to big platforms tend to attract the users banned from the original and lack a core vision.

Chandler Carruth's CppCon 2014 talk on writing fast C++, explaining why data structure choice and memory layout matter more than clever algorithms. It covers why standard containers like unordered_map perform poorly on modern CPUs.

Moleman 2 is a feature-length documentary about the demoscene, tracing its rise from 1980s Commodore 64 culture to modern real-time art. It explains the algorithms and creative process behind demos and intros.

Guy Steele presents a small geometric problem and compares four computational approaches: a classic sequential solution and three parallel-friendly ones. Each is illustrated pictorially and with working code, weighing total work against time to solution.

Sean Parent's GoingNative 2013 talk surveys new and overlooked C++ features and shows how to use them for simple, correct, clear code. It stresses using standard algorithms rather than raw loops.

Chris Stucchio presents the ethical principles behind algorithmic decision making and shows with examples from lending, criminology and education that they cannot all be satisfied at once. The talk frames AI fairness as a set of quantitative tradeoffs.

A Channel 4 News interview with technologist Jaron Lanier, who argues that social media damages people's lives. He discusses how Facebook, YouTube and Google use algorithms and data collection to shape what users see.

A YouTuber explores the Chernobyl zone in 2013, takes a gamma spectrum of a hot reactor fuel fragment, and jokes about a radioactive ant bite. It is a hands-on amateur look at radiation in the exclusion zone.

A restored 1994 video of Karl Sims' research on evolved virtual creatures, where simulated block creatures are bred through artificial evolution to swim, walk, follow and compete. It is a landmark demonstration of genetic algorithms in physics simulation.
