A short BicycleDutch episode showing how Dutch protected intersections continue cycle paths through the junction without needing extra street width.

A short research demo of Autonomous Intersection Management, a protocol in which self-driving cars reserve slots through an intersection instead of obeying signals or stop signs. It uses UT Austin's autonomous vehicle Marvin and a simulation to show cars crossing without stopping.

A Senate hearing clip in which Sen. Ted Cruz questions a Google executive about alleged political bias and censorship in Google's products. It is a short excerpt of congressional testimony from 2019.

A short BicycleDutch episode showing how Dutch junctions with protected cycle paths are laid out. It argues these are proven, non-experimental designs that make intersections safer for cyclists.

An 86-minute Milton Friedman talk arguing that inflation is a monetary phenomenon caused by money supply growing faster than goods, and that the cure is less government spending and money printing.

Rowan Atkinson's speech at the launch of the Reform Section 5 campaign in Parliament in 2012. He argues against criminalizing insulting words and for answering speech with more speech.

Trevor Paglen's 30C3 talk on photographing and documenting the secret state, including CIA flights, spy satellites and military sites, to reveal the geography of covert programs.

Douglas Crockford's YUIConf 2011 keynote on why programming style matters, particularly in JavaScript. He draws on science about the brain and shows how tools like JSLint help.

Google's Amin Vahdat gives the ONS 2015 keynote on Google's datacenter networking, including its custom hardware, software-defined networking and very high bisection bandwidth.

A Waymo clip, sped up 3x, showing its autonomous car stopping at a broken traffic light and proceeding on a police officer's hand signals.

A Real World Crypto 2017 talk by a Google engineer on using private set intersection to match ad views with in-store purchases. It describes privacy-preserving matching that avoids exposing personal transactions.

Cities: Skylines experiment measuring traffic flow across 30 different four-way junction designs, comparing vanilla traffic AI with the TMPE mod.

Tom Scott explains why Ipley Cross in England's New Forest was one of Britain's most dangerous junctions. The angled crossroads lets a car's A-pillar hide approaching traffic and cyclists because there is no relative motion in the driver's view.

Not Just Bikes explains how Dutch traffic lights use early detection, transit priority and conflict-free design to cut waiting. The aim is to move as many people as possible rather than as many cars.

A short clip of Meskel Square in Addis Ababa, a busy crossroads where vehicles and pedestrians mix with few apparent rules. Filmed in 2013.

The SIGGRAPH 2005 demo of dual photography from Stanford, which swaps the roles of projector and camera to render a scene from the light's point of view. It includes the reveal of a hidden playing card.

Sandi Metz takes an ugly section of conditional code and refactors it into a few simple objects, bridging object-oriented theory and practice. The talk includes her take on the Gilded Rose refactoring kata and the idea that duplication is cheaper than the wrong abstraction.

Robert C. Martin (Uncle Bob) traces the history of software from 1948 to today, looking at the problems programmers faced, how they were solved, and what mistakes the profession made. He then projects where the field is going, including professionalism and regulation.

A 1953 US Navy training film on the basic mechanisms in fire control computers: shafts, gears, cams and differentials. It shows how these mechanical parts compute ship and target firing solutions.

Jeremy Howard's 90-minute practical tour of language models. It covers how they work, GPT-4's capabilities and limits, using the OpenAI API, code writing, data analysis and fine-tuning.

Not Just Bikes argues that stop signs are a poor traffic control, drawing on Dutch practice and the Idaho stop to show intersections can be safer without them, especially for cyclists.

In the finale of Double Fine's Devs Play, speedrunner SMK demonstrates glitches and exploits that skip entire sections of Psychonauts while Tim Schafer and the dev team watch. The developers react to and discuss the bugs as they appear.

Psychologist Philip Zimbardo explains how ordinary people can be pushed into doing evil by situations and systems. He draws on the Stanford prison experiment and unseen Abu Ghraib photos, then turns to the opposite case: how ordinary people can become heroes.

Rowan Atkinson speaks against the word 'insulting' in the UK Public Order Act, as part of the Reform Section 5 campaign. He argues for robust free speech and against the slippery slope of criminalizing offense.

Historian Doron Swade tells the story of Charles Babbage's quest to build the Difference Engine and the construction of Difference Engine No. 2 at the Science Museum. The talk covers Babbage's motivation, his machines and Ada Lovelace's insight into the Analytical Engine.

A short urbanism video presenting original observations of how drivers treat stop signs, to argue that cyclists rolling through them under an Idaho stop is no different. It filmed intersections in Ottawa.

John Oliver covers student debt and the for-profit colleges that push students into it, including Corinthian-style schools and ITT Tech. It is a segment from Last Week Tonight.

Rick Falkvinge responds to viewer feedback on his earlier Lightning Network video and raises a flaw he says was not previously discussed. The main thread is the network's unsolved routing problem.

An animated short on limits to growth, covering oil formation, peak oil, energy, economic growth and resource depletion. Its central section deals with exponential growth, and the author notes some statistics are dated.

A five-minute BicycleDutch episode showing how Dutch junctions are designed so cyclists and pedestrians can cross safely. It explains the layout choices that separate and protect them.

A clip from Channel 4's Inside Nature's Giants in which Richard Dawkins shows the recurrent laryngeal nerve of the giraffe during a dissection. The nerve takes a long detour down the neck and back up.

Chris Urmson, head of Google's self-driving car program, shows footage of how the car perceives the road and decides what to do. Examples include cyclist hand signals, school buses, police officers and complex intersections.

A short video of railroad workers in Storfors, Sweden, using thermite to weld rail sections together.

A short BBC clip narrated by David Attenborough showing crows in Japan using city traffic to crack nuts, dropping them at intersections and retrieving them when the light changes.

Shrek Retold is a crowdsourced, scene-for-scene remake of Shrek made by over 200 creators, each redoing a short section in their own style.
