The original duck tape had no glue at all. The name comes from the Dutch word doek, a heavy woven cloth, and around 1902 strips of it were wrapped around the Manhattan Bridge's steel cables to protect them from salt air. The sticky version arrived in 1943, when ordnance plant worker Vesta Stoudt saw that the wax-dipped paper tape sealing ammunition boxes cost soldiers precious seconds under fire. Ignored by her supervisors, she wrote directly to President Franklin D. Roosevelt.

This episode follows what happened next. Roosevelt forwarded her letter to the War Production Board, and the Revolite division of Johnson and Johnson produced a three-layer tape of cotton duck cloth, polyethylene, and rubber adhesive that tore by hand and shed water. After the war it turned silver, got wrapped around heating ducts, and picked up a new name, even though it is terrible at that job. The story runs from suburban basements to the Moon and to the panic buying of 2003.

• In 1930 a mechanics magazine printed a home recipe for heavy tape: soak cloth strips in boiling rosin and rubber melted from old inner tubes.
• A 1998 Lawrence Berkeley National Laboratory test found standard duct tape failed on heated ducts, and California later wrote it out of its building codes.
• Jack Kahl bought a small Ohio tape company in the 1970s, renamed the product Duck Tape, put a yellow cartoon duck on it, and won almost half the US market.
• On Apollo 13, astronauts used tape, flight manual cardboard, and plastic bags to fit square carbon dioxide canisters into a round socket. Engineer Ed Smylie said he knew they would survive once the tape was confirmed aboard.
• In February 2003, Homeland Security advice to buy plastic sheeting and duct tape emptied store shelves, though sealing a room at home was nearly impossible.

In 1946, Douglas Engelbart was a young Navy radar technician in the Philippines when he read Vannevar Bush's essay As We May Think in a Red Cross library. Bush imagined the Memex, a microfilm desk that linked documents by association, the way the mind works. Engelbart carried the idea into a world of punch cards and batch processing and concluded that computers should do more than calculate. They should augment human intellect, so people could manage problems growing faster than their brains could.

This episode traces that conviction from his Augmentation Research Center at the Stanford Research Institute to the stage in San Francisco on December 9, 1968. There, in 90 minutes, he showed the mouse, overlapping windows, linked documents, and live collaborative editing with video. It also follows what came after: an industry that applauded and went back to batch processing, a team that scattered to Xerox PARC, and a founder who watched his tools get sold without his purpose.

• Engelbart's team practiced bootstrapping, using each tool they built to build a better one, much as a carpenter uses a crude hammer to make a finer hammer.
• The SDS 940 mainframe stayed in Menlo Park, about 30 miles away, linked to the stage by leased phone lines, custom 1200 baud modems, and microwave video beamed off a mountain.
• Bill English, who built the wooden mouse from Engelbart's sketches, ran the video feeds backstage while Stewart Brand operated a camera at the lab.
• Former team members helped engineer the Xerox Alto by 1973, the machine whose interface Steve Jobs later saw on a tour of Xerox PARC.
• Engelbart felt a deep sense of loss as the interface spread and the philosophy was dropped, leaving him remembered mainly as the inventor of the mouse.

Digg launched in 2004 as an experiment by Kevin Rose, Jay Adelson, Owen Byrne, and Ron Gorodetzky: take the front page away from editors and hand it to the crowd. Users submitted links, then dug them up or buried them. Creative director Daniel Burka's little yellow thumb with a number beside it became the ancestor of every like button. By 2008 the site drew over 236 million visitors a year, and a front page spot could melt a target site's servers.

This episode follows the twenty year arc from that rise to a spectacular fall and an unlikely revival. It covers the paid promoters and voting blocs who gamed the algorithm, the 2007 revolt over a leaked HD DVD encryption key, and the 2010 Version 4 redesign that removed the bury button and drove users to Reddit. It ends in 2026, with Rose and Reddit's Alexis Ohanian relaunching Digg, only to see open voting overrun by bots.

• Because early votes carried extra weight, a small coordinated group could steer the front page, and some top users reportedly charged up to $1,200 for placement.
• When Digg deleted posts containing the leaked AACS key, users flooded the site with the code in what one called a digital Boston Tea Party, and management backed down.
• On August 30, 2010, known as Quit Digg Day, users wired the auto-submit feature to Reddit feeds and filled the front page with links to the rival site.
• In 2012 the Digg brand, site, and technology sold to Betaworks for $500,000, after rumored talks with Google at around $200 million.
• The public beta opened in January 2026 and closed two months later. Digg rebooted on May 11, 2026 as an AI-driven aggregator built around roughly 2,000 trusted voices on X.

The dark web is smaller and stranger than its reputation. It accounts for just 3 percent of daily traffic on the Tor network, and its single biggest hidden service is Facebook. This episode starts with the architecture: the difference between the deep web and the dark web, and how onion routing passes data through three servers, each able to unlock only one layer, so that no single node ever knows both who sent a request and where it is going.

From there it maps the economy that anonymity produced. After Silk Road proved the concept in 2011, darknet markets copied mainstream shopping sites, complete with vendor reviews, escrow, and dispute mediation. Cybercrime now runs as a supply chain of ransomware developers, affiliates, and initial access brokers, with Bitcoin tumblers to launder the proceeds. The episode also weighs the grim reality of abuse networks against the myths, and shows how police catch people the math cannot expose.

• In ransomware as a service, the developer typically keeps 20 to 40 percent of the ransom while the affiliate who deploys the attack keeps the rest.
• Double extortion means stealing data before encrypting it, so victims with good backups can still be threatened with publication on leak sites.
• There has never been a documented murder for hire that began on the dark web. Silk Road founder Ross Ulbricht allegedly paid hundreds of thousands of dollars to fake hitmen.
• Red rooms are a hoax and a technical impossibility, because Tor's three-hop routing is far too slow for live video.
• After seizing the Playpen server, the FBI ran the site for nearly two weeks and used a network investigative technique to capture users' real IP addresses.

Creepypasta takes its name from 4chan slang around 2007: a horror version of copypasta, the blocks of text users copied and pasted across message boards. Its roots run back to 1990s chain emails and to Ted the Caver, a 2001 story formatted as a personal web journal with dates and photographs. By 2005 anonymous users were crowdsourcing a monster called the Rake, inventing fake historical documents such as a 1602 mariner's log to prove it existed.

This episode follows the genre from its 2010 peak, when the Creepypasta Wiki and Reddit's NoSleep forum launched, through its favorite tricks: first-person narrators, embedded links and doctored images, lost episodes of beloved cartoons, and haunted video games like Ben Drowned and Sonic.exe. It also confronts the real violence tied to these stories, and how Hollywood and the Library of Congress came to treat them as the defining myths of the early internet.

• Folklorists call these stories anti-legends: unlike a traditional legend with a moral, they offer no lesson or resolution and aim only to undermine a reader's sense of safety.
• Lost episode tales such as Squidward's Suicide, Dead Bart, and SuicideMouse.avi work by turning childhood nostalgia into a threat.
• In the 2014 Wisconsin stabbing, two 12-year-old girls attacked a friend to appease Slender Man. Creepypasta.com later posted a disclaimer saying it was a literature site, not a cult.
• The Backrooms, an endless yellow office maze born on an image board, is becoming an A24 film directed by Kane Parsons, a 17-year-old YouTube creator.
• The American Folklife Center at the Library of Congress has archived creepypasta to preserve the development of digital culture.

In early 1995, Craig Newmark was a newcomer to San Francisco sending a manually typed email list of local tech events to a handful of acquaintances. Inspired by the community spirit of the Well, MindVox, and Usenet, he assumed people wanted parties. Instead, subscribers asked for job postings, then more categories, then a website. By June 1995 he had installed Majordomo to automate subscriptions, and craigslist.org followed when users demanded a web interface.

This episode traces how that list became a company earning an estimated $1 billion a year with a staff of around 50, a plain text design, and almost no ads. It covers the abandoned List Foundation nonprofit plan, incorporation as a for-profit in 1999, and the arrival of Jim Buckmaster, who rose from lead programmer to CEO within 2000. It also examines the eBay lawsuit, crime on the platform, and the laws that forced Craigslist to close whole sections.

• Revenue came from charging businesses, starting with a $25 fee for job posts in cities like New York and Los Angeles, while individual listings stayed free.
• eBay bought a 25 percent stake from a former employee in 2004, then sued in 2008 claiming Newmark and Buckmaster diluted its interest by more than 10 percent.
• Craigslist countersued, accusing eBay of using its board seat to gather confidential information for its rival service Kijiji. eBay sold its stake back in June 2015.
• On September 4, 2010, Craigslist shut its US adult services section, giving up an estimated $44 million in revenue for that year.
• After FOSTA and SESTA carved an exception into Section 230 protections in 2018, Craigslist closed its entire US personals section rather than risk liability.

The Global Positioning System began with a Soviet satellite and two curious physicists. In 1957, William Guier and George Weiffenbach of the Johns Hopkins Applied Physics Lab tuned in to Sputnik 1 and noticed its radio pitch shifting as it crossed the sky. Using the Doppler effect and the lab's UNIVAC computer, they mapped its orbit. Deputy director Frank McClure then asked the inverse question: if you know exactly where a satellite is, can it tell you where you are on Earth?

This episode follows that question through the Navy's Transit system, Cold War submarine targeting, and the 1973 merger of rival military programs into GPS. It credits Roger Easton, Ivan Getting, and Bradford Parkinson, along with Gladys West, whose geodetic model mapped Earth's lumpy gravity, and Elizabeth Essex-Cohen, who studied how the ionosphere bends radio signals. It also explains trilateration, relativity, and how a classified military tool ended up guiding everyday life.

• Transit, launched by the Navy in 1960, used only five satellites and gave a ship a location fix about once an hour.
• Satellite clocks run 38 microseconds fast each day because of relativity, and a single microsecond of error shifts a position by about 300 meters.
• After Korean Air Lines Flight 007 strayed into Soviet airspace and was shot down in 1983, killing 269 people, Ronald Reagan pledged GPS for civilian use.
• During the Gulf War, troops short on military receivers asked families to mail store-bought boating and hunting GPS units, forcing the military to switch off selective availability.
• In 2000, Bill Clinton ordered selective availability permanently disabled, and civilian accuracy jumped from about 100 meters to about five.

Inside Microsoft, the developers building the Office Assistant gave it a code name, TFC, whose first word is unprintable and whose last word was clown. This episode is a full biography of Clippit, the paperclip everyone called Clippy. His roots lie in 1990s Stanford research by Clifford Nass and Byron Reeves, who showed that people treat computers as social actors. Microsoft took the finding literally and put a face on its software. Designer Kevan Atteberry drew the googly-eyed winner, and Bayesian algorithms watched your keystrokes to guess when you needed help.

Released in 1996 with Office 97, the assistant interrupted focused work with offers to help write a letter, and it never learned that its user was no longer a beginner. The episode traces the backlash, the alternate assistants from Einstein to Shakespeare, and the 2001 Office XP campaign in which Microsoft mocked its own creation. It then follows Clippy's afterlife: parody, Easter eggs, an emoji, and an unexpected role in a 2025 protest over data harvesting.

• In Japan the assistant could be a dolphin named Kairu, made famous by a screenshot of a user asking the help box how to delete the dolphin.
• For Office XP, Microsoft built a website about Clippy's unemployment, hired Gilbert Gottfried to voice him, and had a costumed actor dragged offstage by a giant magnet.
• The feature was removed from the code entirely in 2007, and by 2010 Microsoft was showing his tombstone in fake movie trailers.
• A 2021 social media post promising his return as the paperclip emoji at 20,000 likes cleared its goal immediately.
• In August 2025, right-to-repair activist Louis Rossmann urged followers to adopt Clippy as their profile picture to protest data harvesting for AI training.

Claude Shannon's garage held a flame-throwing trumpet, rocket-powered frisbees, a Rubik's Cube solving robot, and foam shoes for walking on water. The same man laid the mathematical foundation of the digital world. Born in 1916 in Gaylord, Michigan, he strung a half-mile telegraph along barbed wire fences as a boy. At MIT, working on Vannevar Bush's differential analyzer, he saw that a switch being open or closed matched the true and false of George Boole's algebra. His 1937 thesis turned circuit design from trial and error into a science.

This episode follows the ideas that came after. At Bell Labs during World War II, Shannon worked on anti-aircraft fire control and cryptography, proved the one-time pad unbreakable, and talked computing over tea with Alan Turing. In 1948 his paper A Mathematical Theory of Communication separated information from meaning, introduced the bit, and set the limits for compression and error correction. Then came a maze-learning mechanical mouse, computer chess, and decades of serious play.

• Shannon's maxim, the enemy knows the system, holds that security must rest entirely on the key, never on a secret machine.
• Theseus, the mechanical mouse he built with his wife Betty in 1950, learned a maze by trial and error and relearned it when the walls moved.
• The Shannon number puts the count of possible chess games at 10 to the 120th power, far beyond the roughly 10 to the 80th atoms in the observable universe.
• With Edward O. Thorp he built the first wearable computer, hidden in a shoe, to predict where a Las Vegas roulette ball would land.
• His rebalancing strategy, known as Shannon's Demon, kept a portfolio split evenly between cash and a volatile stock and reportedly averaged 28 percent a year.

Lorem ipsum fills design templates, broken WordPress themes, and brochure mockups everywhere, and it reads like a mystical Latin incantation. It is in fact a butchered passage from a first century BC treatise in which Cicero weighs the extremes of good and evil and argues that people must sometimes rationally accept pain for a greater good. This episode explains why designers need dummy text at all: readers recognize whole words by reflex, so real copy pulls attention away from typeface, spacing, and layout. Even the name is an amputation, the back half of dolorem, the Latin word for pain.

The detective work belongs to Richard McClintock of Hampden-Sydney College, who before 1982 traced the gibberish to Cicero by hunting one rare word, consectetur, through a concordance. His 1994 letter to Before and After magazine also claimed that printers scrambled the text in the 1500s. The episode follows the evidence to a far later source, then to Letraset transfer sheets in 1966, Aldus PageMaker in the 1980s, and the default templates of the modern web.

• In a 2026 video interview, McClintock admitted his 1500s origin story was a guess with no historical evidence behind it.
• In the 1914 Loeb Classical Library edition, page 34 ends with do- and the next Latin page begins with lorem, a page break that created the famous first word.
• The rest of the filler matches fragments from pages 56, 70, and 118 of that same 1914 book.
• Typography historian James Mosley supplied the scrambled version to Letraset, replacing a more intact Cicero passage used in type manuals since the 1730s.
• One theory holds that the Latin was deliberately garbled to mimic the letter frequency and visual rhythm of English.
