Practical Engineering explains how canal locks work, including the water-saving basins of the new Panama Canal locks.

Practical Engineering explains why San Francisco's Millennium Tower is sinking and tilting, covering how geology and foundation design (friction piles in the Colma Formation) affect skyscrapers. It also covers the fix being attempted.

John Oliver's Last Week Tonight segment on civil asset forfeiture, the process by which police can seize property they suspect is tied to crime. It explains how the property itself is put on trial and how departments profit.

Glenn Vanderburg asks whether software development can be real engineering, surveying other engineering disciplines and decades of programming experience. He envisions what a software engineering worthy of the name might look like.

Glenn Vanderburg argues at the O'Reilly Software Architecture Conference that software development is an engineering discipline, even if immature. He contends the discredited body of knowledge called software engineering has led people to wrongly reject the label.

Hillel Wayne reports on interviews with 17 people who have worked as both software and traditional engineers. He argues the fields are fundamentally the same and have much to learn from each other.

Practical Engineering explains how engineers and agencies put a dollar value on a human life to weigh cost against safety. It covers the legal and regulatory basis for these calculations.

Glenn Vanderburg argues at Lone Star Ruby Conference 2010 that university-style software engineering does not work, and asks what real software engineering would look like. He revisits the waterfall model and what engineering means in other fields.

Chris Domas's DEF CON 23 talk on psychological warfare against reverse engineers. He builds code whose disassembly and control flow graphs mislead, intimidate and demoralize anyone analyzing it.

Tom Scott visits a rotating house near San Diego and explains how electricity, gas and water keep working on the rotating part. It includes a 3D render of the utility connection system.

Musician Thoj performs a live looping session on the Teenage Engineering OP-1 synthesizer, building a deep house track layer by layer.

A half-hour television special on the 2007 fiery collapse of a connector in the Bay Area's MacArthur Maze and its rebuilding in 26 days. It was produced for the Professional Engineers in California Government.

Real Engineering explains the engineering behind the James Webb Space Telescope, including its folding mirror, sunshield, orbit and cooling systems, and why deployment was so difficult.

A 2017 GDC postmortem in which Sid Meier and Bruce Shelley tell how Civilization came together from board game design and sim game experience. They cover its development history and design decisions, including fairness and luck.

Tom Scott tells how John Reber's plan to dam San Francisco Bay was disproved by the Army Corps of Engineers' giant hydraulic Bay Model in Sausalito. The model showed the plan would have been dangerously wrong.

Michael Steil's 27c3 talk on reverse engineering the MOS 6502 from die shots into a transistor-level simulation, as in the Visual6502 project. It covers going from chip package to a digital model.

Bryan Cantrill's Craft 2019 talk on the ethical dilemmas software engineers face as software eats the world. He explores cases where engineering thinking conflicts with the law or personal morals, including Facebook's news feed experiments.

Matt Parker's Royal Institution talk based on his book Humble Pi, covering everyday mathematical mistakes and spurious patterns that went wrong in engineering and software. It mixes stand-up comedy with stories of coincidence and error.

An episode of the Well There's Your Problem podcast on five-over-one buildings, wood-frame floors atop concrete bases, with engineering background and some oil industry news. It is long, rambling and has NSFW language.

Stuart Armstrong of the Future of Humanity Institute gives an Oxford physics talk on what exploratory engineering suggests about the Fermi paradox. He argues that von Neumann probes and Dyson spheres are plausibly buildable and asks what traces advanced civilizations would leave.

Kurzgesagt asks whether advanced civilizations could have existed on Earth in the deep past and left little evidence. It looks at time as a dimension for searching for alien civilizations and the limits of the geological record.

PBS Space Time examines the Silurian hypothesis, the idea that an industrial civilization could have existed on Earth before humans. It looks at what traces such a civilization might leave in the geological record.

A short clip demonstrating a phone-based social engineering trick in which a crying baby in the background is used to pressure a customer service rep. It shows how attackers exploit human sympathy rather than technical flaws.

An engineering explainer on why Tesla abandoned the induction motor for the Model 3 and used an IPM-SynRM design. It covers the reluctance torque and permanent magnet principles behind the choice.

Practical Engineering's explanation of the February 2021 Texas winter storm and the resulting power grid outage. It lays out the facts about ERCOT, the grid's isolation, and how generation across fuel types failed in the cold.

Real Engineering examines whether greening the Sahara could draw down carbon and slow climate change. It concludes that the effort would be enormously costly and that changes in albedo and other effects undercut the climate benefit.

Tim Dodd of Everyday Astronaut tours SpaceX's Starbase with Elon Musk as guide. They cover the high bay, grid fins, Raptor V2, the HLS lander and stage separation, and Musk explains his engineering management process.

An Isaac Arthur episode on civilizations in the dark, post-stellar universe, including black hole farming, accretion disks and the Penrose process as energy sources.

The introductory lecture of Richard Hamming's capstone course, The Art of Doing Science and Engineering: Learning to Learn. It focuses on style of thinking and on educating rather than training, using technical material only as illustration.

Tourist footage of the 660-ton tuned mass damper in Taipei 101 swaying during tremors from the 2008 Sichuan earthquake. The damper hangs from the 92nd floor.

Soren Johnson, a lead designer and AI programmer on Civilization games, discusses game AI design, including whether AI should cheat, behave like a human or be fun rather than strong. He uses the Civilization series as a case study.
