Grandma Ada hits the runway
Ada, Its Design, and the Language That Built the Languages
Old DoD language gets a glow-up as devs bicker: genius, boring, or secretly AI-made
TLDR: An old, safety-first language built for the U.S. military quietly shaped today’s programming, and now the internet is arguing whether that’s genius or just boring-but-safe. Comments split between praising caution, calling for network-wide safety, and alleging the site is AI-written.
Meet Ada, the safety-obsessed, government-built grandparent of modern code. The article claims this 1970s U.S. Department of Defense language quietly invented the good stuff: clear interfaces, safe types, and even a chatty way for programs to talk that Go later called “channels.” It was born after the DoD found 450 incompatible languages running weapons and logistics—cue a five-year spec marathon called Steelman. Ada’s brand? The language that says “no” to risky code, which is why it flies on your plane and sleeps just fine about it. Think “boring on purpose,” but powerful—Ada as the unseen style icon of software.
The comments? Spicy. Fans cheer the safety-first vibe—one user celebrates HN’s “move slowly and preserve things,” dunking on Silicon Valley’s “break things” era. Futurists push harder: “make it memory-safe across the network,” and even one language to span software and hardware design. The nerd-fight of the day: “What’s Ada’s version of Rust’s one-use rules?” sparks explainers and eye-rolls. Then chaos: a commenter declares “The entire site is AI written,” igniting a meta-brawl about authenticity. Meanwhile, the article’s snarky rope/noose line becomes a meme, with folks joking that Grandma Ada still ties the safest knots in tech.
Key Points
- •Ada, commissioned by the U.S. Department of Defense, emphasized safety and verification, introducing features like built-in concurrency, strict interface/implementation separation, and language-level contracts.
- •The article states that Ada’s standard has been revised four times since 1983 and that Ada is used in software for every commercial aircraft currently in service.
- •Ada’s design influenced later languages: Go’s channels-like communication model, and convergence in Rust, Python, and C# toward Ada-like safety and structure.
- •In the early 1970s the DoD found 450+ languages and dialects across its systems, creating severe maintenance and interoperability problems.
- •The DoD ran a five-year requirements effort (Strawman through Steelman, issued in 1978) instead of adopting COBOL, Fortran, or PL/1, leading to Ada’s specification.
