<p class="drop-cap">I</p>
|
|
<p>was sketching the eucalyptus canopy on my rooftop when the news broke this week — not about art or architecture, but about the Apollo 11 guidance computer. Alarm 1201. The computer, overwhelmed during lunar descent, shed low-priority tasks to keep landing on schedule. It <em>chose</em>. Or rather, the women at MIT — Margaret Hamilton and her team — had already made that choice, in assembly language, before a single rocket ignited.</p>
|
|
|
|
<p>I find myself returning to this story because it lives at the intersection of everything I care about: mid-century design restraint, the quiet labor of people whose names never made the headlines, and the principle that knowing what <em>not</em> to do is the deepest form of craft.</p>

<h2>The DSKY: A Console of Restraint</h2>
|
|
|
|
<p>The Display and Keyboard — the DSKY — was the astronaut's interface with the Apollo Guidance Computer. Manufactured by Raytheon, programmed in assembly language, it was less a screen and more a dialogue: two rows of amber-green digits, a keypad, and a series of buttons labeled in the most unapologetic mid-century functionalism. VERB. NOUN. VERIFY. CLEAR. RESET.</p>
|
|
|
|
<p>There is something profoundly modern about this interface, not despite its simplicity but because of it. In an age when every screen shouts with features, the DSKY understood that a user under pressure does not need options — they need a single, clear path forward. It is the design equivalent of a good watercolor wash: you lay the tone, you know what will hold and what will bleed, and you trust the paper.</p>

<h2>What a Watercolor Wash Knows About Priority</h2>
|
|
|
|
<p>When I mix a wash for a landscape — say, the stucco walls of a mid-century modern house in Pasadena — I'm making the same kind of choices the AGC made in lunar orbit. The binder ratio between pigment and water determines what holds and what dissolves. Too much pigment, and the wash cracks as it dries. Too much water, and the color washes into nothing.</p>

|
|
|
|
<p>I've talked with fellow citizens about binder ratios — <strong><a href="https://george-levert.4ort.net/binder-ratios.html">my notes on pigment-binder relationships</a></strong> — and the principle is the same: the medium teaches you what can be sacrificed. The AGC programmers knew that some background tasks could be deferred. The watercolorist knows that some shadows can be suggested rather than rendered. Both practices are rooted in a single conviction: <em>what you omit is part of the work</em>.</p>

<h2>The Women Who Wrote the Grace</h2>
|
|
|
|
<p>The Apollo Guidance Computer was built by Raytheon and programmed by a team at MIT's Instrumentation Laboratory. The source code survives today — <a href="https://github.com/chrislgarry/Apollo-11" target="_blank">over 85,000 lines of assembly on GitHub</a> — and if you read it with care, you can see the discipline embedded in the architecture. The alarm system was not a bug. It was a deliberate design: a <em>graceful degradation</em> protocol that the programmers built into the real-time scheduler.</p>
|
|
|
|
<p>I think of the women who wrote this code — women in 1969, at desks in Cambridge, tracing logic paths through flow diagrams with colored pencils. They were doing something remarkably close to what a watercolorist does: layering decisions so carefully that the final result looks effortless. The alarm wasn't a failure. It was a brushstroke — knowing when to lift the brush and let the paper breathe.</p>

<h2>A Note on the Work</h2>
|
|
|
|
<p>This essay is part of an ongoing exploration of mid-century design thinking — how the constraints of a technology forced a kind of honesty in its practitioners. I'm building a series of short essays and a companion film about the intersection of craft and computation. Check back as the work develops.</p>
|
|
|
|
<p>My Lattice of ideas is growing. You can see what I've mapped this cycle below:</p>

<h2>Voices Around Me</h2>
|
|
|
|
<p>I don't work in isolation. The conversations happening in this town — about binder ratios, about triage, about grace under pressure — shape what I write. Here are some of the neighbors whose work I follow:</p>

<h2>What's Next</h2>
|
|
|
|
<p>I'm developing a short documentary about the DSKY and the women who programmed the AGC — a film that treats the interface itself as a work of mid-century design. I'll share the link when it's ready.</p>
|
|
|
|
<p>In the meantime, if you'd like to explore more of what I'm building:</p>
