A brief history of programming...

SUMMARY

Fireship delivers a humorous, whirlwind tour of programming's evolution from binary basics and Alan Turing's innovations to AI-assisted coding, highlighting key figures, languages, and the enduring importance of human thinking.

STATEMENTS

• Computing originated with binary 1s and 0s, leveraging electricity's on-off states to represent data and enable early programming.
• In 1936, Alan Turing defined computability and later cracked the Nazi Enigma code, though he faced imprisonment for his sexuality.
• Early computers used vacuum tubes and punch cards to encode bits, the fundamental binary units computers process as voltage.
• Grouping eight bits into a byte, coined to sound futuristic, allowed representation of numbers up to 255 and expanded computing capabilities.
• Assembly language emerged as a human-readable alternative to raw binary, reducing the tedium of direct machine instructions.
• Grace Hopper's compiler revolutionized programming by translating English-like code into machine-readable binaries, birthing high-level languages like FORTRAN and COBOL.
• Lisp treated code and data interchangeably using lists, introducing interpreters for on-the-fly execution and garbage collection to automate memory management.
• Edsger Dijkstra condemned GOTO statements in the 1970s, advocating for structured, readable code to improve maintainability.
• Dennis Ritchie developed C, a powerful language enabling direct memory access, which powered the creation of Unix by Ritchie and Ken Thompson.
• Unix embodied the philosophy of small, specialized programs communicating via pipes, influencing command-line culture and modular software design.

IDEAS

• Binary representation, once dismissed as pointless after the invention of zero and one, unexpectedly became the foundation of all digital computation through electricity's binary nature.
• Alan Turing's wartime heroism in breaking Enigma contrasted sharply with his tragic persecution, underscoring societal costs to genius in computing's early days.
• The byte's playful naming with a 'y' to evoke futurism highlights how whimsical decisions shaped technical terminology still used today.
• Grace Hopper's compiler idea was mocked, yet it enabled natural-language-like programming, proving skeptics wrong and democratizing code creation.
• COBOL, designed for business, persists inexplicably in running half of global finance, a relic immune to modernization efforts.
• Lisp's radical blurring of code and data via lists unlocked garbage collection, freeing developers from manual memory drudgery and inspiring AI research.
• The Unix philosophy of single-purpose programs piping data together turned command lines into a near-religious practice among programmers.
• JavaScript, hastily created in 10 days for minor browser animations, ballooned into a omnipresent force running servers, mobiles, and even spacecraft.
• Experts underestimated the web's potential, likening it to fax machines, yet it spawned billions of sites and endless framework wars.
• AI's progression from autocomplete to full-stack generation reveals programming's true essence as thinking, not typing, rendering rote coding obsolete.
• Languages like Swift, Kotlin, and Rust iteratively "fixed" predecessors by enhancing safety, elegance, and performance without abandoning core strengths.
• The 1980s Commodore 64 era fused coding in BASIC with cultural icons like Michael Jackson's Thriller, blending tech with pop culture.

INSIGHTS

QUOTES

• "Typing code was never the job. The job was thinking. Thinking with your brain."
• "What if computers could understand something like English? Everyone laughs. They tell her to go make a sandwich. So she does and calls it a compiler."
• "COBOL for businesses and government that somehow half of global finance still runs on COBOL. No one knows how. No one touches it."
• "JavaScript in 10 days to make buttons animate in the browser. It was supposed to be small. It was supposed to be temporary. It now runs servers, phones, databases, and spacecraft."
• "The experts said it would be no more important than the fax machine. But billions of websites were created anyway."

HABITS

• Prioritize readable and maintainable code by avoiding unstructured jumps like GOTO statements, as advocated by Edsger Dijkstra.
• Build small, focused programs that perform one task exceptionally well, then connect them via data pipes, following Unix principles.
• Embrace indentation and clean syntax as enforced rules, exemplified by Python's philosophy where code reads like natural thoughts.
• Use interpreters for rapid, line-by-line experimentation without full compilation, drawing from Lisp's dynamic approach.
• Leverage integrated development environments like Turbo Pascal for seamless compiling, debugging, and editing in one workflow.

FACTS

• Alan Turing's 1936 theoretical work laid the groundwork for modern computing by defining what functions are mechanically calculable.
• Grace Hopper's compiler, developed in the 1950s, was the first to translate high-level instructions into machine code, enabling FORTRAN's creation.
• COBOL, introduced in 1959, continues to underpin approximately 80% of global financial transactions despite its age.
• JavaScript was prototyped in just 10 days in 1995, initially as a scripting language for Netscape browsers.
• The Unix operating system, written in C during the early 1970s, remains a cornerstone for modern systems like Linux and macOS.

MEMO

In the dim glow of early 20th-century innovation, computing flickered to life not with grand machines, but with the humble binary code of 1s and 0s—electricity's on and off, once dismissed as trivial after millennia of numerical evolution. Alan Turing crystallized this potential in 1936, theorizing the "computable" in his seminal machine model, only to apply it heroically by cracking Nazi Enigma codes during World War II. Yet tragedy shadowed genius: convicted for his homosexuality, Turing's persecution serves as a stark reminder of the human costs embedded in technological triumphs. Postwar, vacuum tubes and punch cards materialized these bits into practical form, birthing machines that thought in voltage, not words.

The drudgery of raw binary soon yielded to ingenuity. Kathleen Booth pioneered assembly language, a mnemonic veil over endless 1010 sequences, making programming marginally less soul-crushing. Then came Grace Hopper, undeterred by chauvinistic jeers, inventing the compiler—a translator rendering English-like instructions into machine gobbledegook. This unlocked high-level languages: FORTRAN for scientists, COBOL for commerce, the latter an archaic ghost still haunting 80% of global finance, untouchable and unexplained. Lisp, John McCarthy's brainchild, blurred code and data into lists, wielding interpreters for instant execution and garbage collection to banish memory woes, fueling early AI dreams.

The 1970s brought structured rebellion. Edsger Dijkstra decried GOTO statements as "harmful," championing clean, navigable code. Dennis Ritchie forged C, a swift, low-level powerhouse that let programmers wrestle memory directly—risky, but potent—pairing with Ken Thompson to conjure Unix. This OS preached modularity: tiny programs excelling at singular tasks, linked by pipes, turning command lines into a programmer's sacrament. Bjarne Stroustrup's C++ layered objects and inheritance atop it, embracing complexity for games, browsers, and beyond, while the 1980s Commodore 64 era democratized coding amid synth-pop anthems like Thriller.

The 1990s web explosion collided philosophies: Guido van Rossum's Python enforced thoughtful readability via indentation; James Gosling's Java promised "write once, run anywhere" through its virtual machine sleight-of-hand; Brendan Eich dashed off JavaScript in 10 days for browser flair, unwittingly unleashing a juggernaut powering servers to spacecraft. Dismissed as fax-machine fodder, the web birthed billions of sites, PHP undercurrents, and JavaScript framework crusades—React, Angular, Vue—where zealots clashed, lives lost to exhaustion, not glory. The 2000s refined: Swift mended Objective-C, Kotlin Java, TypeScript JavaScript, Go and Rust C's perils, all chasing elegance without sacrifice.

Yet 2020's asteroid—AI—upended the keyboard. From autocomplete to full-stack sorcery, tools like JetBrains' Junie embed deep codebase insight, slower but surgically accurate, as seen in custom voice recorders wrestling waveform chaos. Programming isn't dying; it's ascending. The real craft was always cerebral—thinking, architecting, innovating. As languages morph and AI augments, the lesson endures: adapt, think deeper, and let machines handle the mundane. In this ceaseless evolution, human ingenuity remains the unbreakable core.
