structural integrity

A short unscientific fire test comparing a massive timber house with an ordinary house. It shows the wood chars and burns slowly while still holding together.

A podcast episode of Arrested DevOps with Andrew Clay Shafer and Bryan Cantrill, featuring Cantrill's rant on integrity in companies and technology.

A short video of a Boeing 777 wing being tested to destruction, finally breaking at 154 percent of its designed limit load. The wing is flexed upward until it fails.

A Tom Scott guest video by Grady Hillhouse of Practical Engineering on the 1981 Hyatt Regency walkway collapse. A seemingly minor change to the support design led to catastrophic failure, which is why the case is taught as a lesson to check and double-check everything.

Shaun Lebron surveys 50 years of Lisp editing history and forgotten innovations in structural editing. He argues future Clojure editors could learn from them, and covers ideas like Parinfer.

A one-minute clip of an Atlas Agena rocket losing pressure on the pad and collapsing. The Atlas relied on tank pressurization for structural integrity, so a simple failure tore it apart.

A three-minute Emacs Rocks screencast by Magnar Sveen demonstrating paredit, which edits Lisp code structurally as a tree of s-expressions rather than characters.

Bryan Cantrill of Joyent presents Manta, an internet-facing object store that lets you run compute directly on the data. The talk is peppered with ZFS history and Cantrill's trademark commentary on the industry.

Jeff Bonwick and Bill Moore, the creators of ZFS, present 'ZFS: The Last Word in File Systems' at the 2008 SNIA Software Developers' Conference. They explain the design, including copy-on-write, checksumming and avoiding the write hole.

A short demo of SEdit, the structure editor for Interlisp-D on Xerox Lisp machines in the 1980s, which edits code as trees rather than text.

Rick Hartley gives a roughly two-hour live training on proper grounding in PCB design. He explains how energy actually flows in the space between conductors, and how that governs noise, EMI, return paths and signal reflections.

Rick Hartley's AltiumLive keynote on differential pairs in PC boards. He argues the rules from cables and twisted pairs do not carry over, and covers which pair geometry gives the best impedance control, the right spacing, routing practice and how much skew is acceptable.

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.

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.

Destin Sandlin of Smarter Every Day investigates manipulation on Facebook, interviewing the company's team about content moderation. It is the third video in his series on social media manipulation.

Linus Tech Tips tests whether chaining many PCIe riser extensions causes loss of GPU performance. They keep adding extensions to see how far the signal will go.

A one-minute clip from Insider showing an Airbus airliner's wings flexing far more than most people expect during a wing load test. It is meant to reassure nervous flyers about turbulence.

Destin Sandlin tours United Launch Alliance's rocket factory with CEO Tory Bruno, showing friction stir welding, structural rocket skins and large milled parts.

Ava DuVernay's Oscar-nominated documentary on how the history of racial inequality in the US, from slavery through the 13th Amendment's exception clause, drives mass incarceration. It combines archival footage with testimony from activists and scholars.

A videogamedunkey video essay on video game critics. It argues that a critic's taste and integrity matter as much as their score, and tries to explain why major outlets give such inflated ratings.

Dr. Howard Schubiner presents his research that much chronic pain comes from learned neural pathways rather than structural damage, and outlines a treatment approach based on that view.

An Al Jazeera English People & Power investigation from 2010 into safety problems with the Boeing 737NG, featuring whistleblowers on cracking parts, hand-made structural components and an alleged cover-up.

Alex Martelli's Google Developers Day talk on classic design patterns (creational, structural and behavioral) and how they appear in Python. He stresses that patterns must be studied in the context of the implementing language.

Yanis Varoufakis talks at a festival in Zagreb about his book The Global Minotaur. He argues the postwar global economy and the 2008 crisis stem from deeper structural causes than greed or weak regulation.

Sandy Munro interviews Elon Musk at Boca Chica about Tesla production, mega-castings, seats, structural battery packs and the difficulty of mass production.

Pokey Rule presents Cursorless, a spoken language designed for editing code by voice, built on tree-sitter parsing with smart structural and simple token-level primitives. The talk is from Strange Loop 2023.

A Last Week Tonight segment on sponsored content in local news. John Oliver explains why local news integrity matters and how paid content disguised as news erodes it.

A RacketCon talk presenting Fructure, a prototype extensible structured editing engine in Racket. Language providers define syntactic forms and refactorings as rewrite rules, and editing operates on program structure rather than on text.

A short excerpt of Noam Chomsky telling a BBC journalist that he does not accuse him of self-censorship. He argues that people who believed differently would not have been hired into that position.

Short British Pathe newsreel footage of the 1940 collapse of the Tacoma Narrows Bridge as it twisted and swayed in the wind. The only casualty was a dog left in a stalled car.
