Computing

Ada Lovelace wrote the world's first computer program in 1843 for a machine that was never completed. Her vision of what computing could become was so far ahead of its time that it wasn't fully appreciated for over a century.

Nintendo is one of the world's most recognizable video game companies, but it existed for over 90 years before it made a single video game. Its story begins in 1889 in Kyoto, where a craftsman named Fusajiro Yamauchi began hand-painting playing cards — and from that modest origin grew one of the most consequential entertainment companies in history.

The phrase 'in a jiffy' implies something happening very fast — and in computer science, that casual expression has been formalized into a precise technical unit representing a single cycle of a computer's system clock.

Before robots existed in any physical form, a Czech playwright named Karel Čapek gave them their name — and their defining narrative: artificial beings who do humanity's labor, grow conscious of their condition, and eventually rise against their creators.

Long before integrated development environments or version control systems existed, the software that guided astronauts to the Moon was drafted on paper by teams of engineers working under extraordinary pressure. The story of Apollo's software is one of human ingenuity operating at the very edge of what was technically possible.

In 1980, IBM shipped the world's first gigabyte-capacity hard drive. The IBM 3380 weighed more than 500 pounds, required a refrigerator-sized cabinet, and carried a price tag of $40,000. Today, the same capacity fits on a chip smaller than a fingernail.

The word TYPEWRITER uses only the letters Q, W, E, R, T, Y, U, I, O, and P — the exact keys on the top row of a QWERTY keyboard. This either reflects a clever design choice, a remarkable coincidence, or a very useful sales demo trick, depending on who you ask.

Before Google became a verb, a noun, and arguably the most recognized brand on Earth, it operated under the unglamorous name 'Backrub.' Understanding why reveals something important about how the early internet worked — and how close we came to a very different technological era.

In 1956, Ampex Corporation unveiled a machine that could record and play back television video. It weighed 750 pounds, stood as tall as a piano, and cost $50,000 — roughly half a million dollars in today's money. It also changed the world.

In 1964, Doug Engelbart carved a small wooden box with two perpendicular wheels on its underside and a single button on top. He called it an 'X-Y position indicator for a display system.' The world would eventually call it a mouse.

Mark Twain purchased one of the first Remington typewriters available to the public in the early 1870s, and 'Life on the Mississippi,' published in 1883, is widely cited as the first book-length manuscript submitted to a publisher having been typed rather than handwritten.

The Trojan Room Coffee Pot camera, installed in the Cambridge University Computer Laboratory in 1991, was the world's first webcam. It was built for the most human of reasons: computer scientists were tired of making the trip to the kitchen only to find an empty coffee pot.

In 1965, Gordon Moore looked at four years of data points and extrapolated a trend line. His prediction — that transistor density on microchips would double roughly every two years — turned out to be one of the most accurate long-range forecasts in industrial history, reshaping civilization for half a century.

Every time you type on a keyboard, you are using a layout designed in the 1870s for a machine that no longer exists, to solve a mechanical problem that modern technology eliminated decades ago. QWERTY persists not because it is optimal, but because of one of the most powerful forces in human behavior: the cost of changing something that already works well enough.

In the early 1970s, IBM researchers developed a language for querying databases that was so well-designed it has outlasted generations of programming languages, computing paradigms, and technology revolutions. SQL — Structured Query Language — is still how the world talks to its most important data.

In December 1989, a Dutch programmer named Guido van Rossum started a new programming language as a holiday project. He wanted it to be fun to use, and he named it after the British comedy group Monty Python. Thirty-five years later, Python is the most widely used programming language on Earth.

In August 1991, a 21-year-old Finnish computer science student posted a message to an internet newsgroup saying he was writing a free operating system 'just a hobby, won't be big and professional.' That casual announcement introduced Linux to the world — a kernel that now runs more than 90% of the world's servers, all Android smartphones, and every supercomputer on the TOP500 list.

In 1945, a machine filled an entire room, weighed as much as a loaded semi-truck fleet, and drew so much power it reportedly dimmed the lights of an entire Philadelphia neighborhood when switched on. It was called ENIAC — and it could perform 5,000 additions per second, making it the fastest calculator in the world.

In 1843, a woman translated an Italian paper about a machine that had never been built, then added notes three times as long as the original — including the first algorithm ever designed to be executed by a computer. The machine was never completed. The algorithm was correct.

Every time you shut down your computer without saving, you lose your work. This is not a design flaw or a software failure — it is a direct consequence of the physical mechanism that makes RAM fast enough to be useful in the first place. Understanding why RAM is volatile reveals something fundamental about the tradeoffs at the heart of computer architecture.

In January 1975, a mail-order electronics kit appeared on the cover of Popular Electronics magazine. It had no keyboard, no monitor, no storage, and no software. Programming it meant flipping switches on the front panel. It sold out immediately, inspired two Harvard students to drop out and write software for it, and started a revolution.

Software engineers spend a substantial portion of their professional lives hunting bugs. The word's origin in computing can be traced to a specific afternoon in September 1947, when a technician at Harvard found a moth caught between the relay contacts of the Mark II computer — and taped it into the logbook with the note 'First actual case of bug being found.'

The Intel 4004, released in November 1971, was designed to power a Japanese desktop calculator. It had 2,300 transistors and could perform about 92,000 operations per second. It was also the ancestor of every microprocessor in every computer, smartphone, and data center on Earth today.

In 1971, a programmer wrote a program that copied itself across ARPANET computers and displayed a taunting message. It was not malicious — it was more of an experiment, perhaps even a prank. But Creeper was the first self-replicating program in computing history, and it inadvertently launched an arms race that has never stopped.

In 1956, IBM introduced a data storage device that weighed over a ton, occupied the space of two large refrigerators, required its own air compressor, and stored five megabytes of data. Renting it cost around $3,200 per month. Today, a device 10,000 times smaller stores 10 million times more data.

Touch interfaces feel like a natural, intuitive way to interact with technology. What feels natural took over 40 years to move from a defense research lab in rural England to the pocket of every smartphone user on the planet — a journey through military technology, ATMs, musical instruments, and eventually the consumer electronics revolution.

Quantum computers do not compute faster by running the same algorithms with bigger numbers — they compute differently, exploiting quantum mechanical phenomena that have no analog in classical physics. The qubit's ability to exist in a superposition of states is the foundation of that difference, and understanding it requires a brief trip into the physics of the very small.

Every email, every photograph, every video game, every financial transaction, and every AI response is ultimately expressed as a sequence of 0s and 1s. This is not an arbitrary choice — it is a physical necessity imposed by the most fundamental behavior of the semiconductor devices that power all digital computing.

In April 1961, at MIT's centennial celebration, a mathematician named John McCarthy suggested that 'computation may someday be organized as a public utility.' He made this prediction a decade before the internet, three decades before the World Wide Web, and four decades before Amazon Web Services would make it a commercial reality. The idea was so far ahead of its time that it had to be reinvented independently by a new generation of engineers before the technology could support it.

In April 2005, Linus Torvalds sat down to solve a specific problem: the Linux kernel project needed a new version control system after the one it had been using became unavailable under acceptable terms. He gave himself one week to have something working. He had a usable system in about two weeks. He named it Git — British slang for an unpleasant person — and it has since become the universal foundation of modern software development.

The computer that guided Apollo 11 to the Moon and back operated at 0.043 MHz and had 4 kilobytes of RAM. A mid-range smartphone in 2026 has a processor running at 3,000 MHz and 8 gigabytes of RAM. The comparison is so extreme it borders on the surreal — which makes it a perfect lens for understanding how radically computing has transformed in 55 years.
