SF:// — slow place. fast signal.

Shortwave

SF://shortwave — a peripheries playground that calls · builds · shows

SF://shortwave is not a *publication* — it’s a *playground*. Someone tosses a one-line *callsign signal*; someone else takes it to an external AI builder and *builds it on the spot*; the result is brought back into a catalog and *shown*. A shortwave radio that punches through where the big-city antenna doesn’t reach — but this time, not for *receiving*, for *conspiring*.

/ 01 · SIGNAL

A one-line callsign — a topic, question, or seed thrown by an editor or sender.

/ 02 · BUILD

Lovable · Bolt · v0 · Replit · Claude · Gemini — one click, signal auto-prefilled.

/ 03 · SHOW

A catalog of made things — essays · web apps · demos · images · experiments · failures all valid.

The era of grand-imagination

The resolution of imagination determines the resolution of the result. Type vaguely → vague result. Describe with care → a precise object.

Make this line in any form — visualization, demo, experiment, web page, short essay. Small is OK, failure is OK. Send the result; we’ll catalog it in SHOW.

Shortwave operating rules

  • SIGNAL is one line — a callsign of one line to one paragraph is enough. Thrown by editor or sender. Not a paraphrase of global trends, but a *question from our seat*.
  • BUILD is one click — external AI builders (Lovable · Bolt · v0 · Replit · Claude · Gemini) provide the sandbox. We only handle signal auto-prefill. A self-hosted sandbox is a long-term goal.
  • SHOW: small is OK — essays · web apps · prototypes · images · demos · experiments · failures all valid. Not big-tech release notes — *attempt reports*.
  • Primary references — list the builder · model · prompt used.
  • Editor-curated — every SIGNAL · SHOW passes editor (Dr. Chi-hoon Shin) review. No automation. Free · CC BY-NC 4.0.
/ 03 · BUILD

Build it now (external tools)

One click opens an external AI builder with the SIGNAL above auto-prefilled. The tools are big-city — but starting from our seat with our signal is what makes shortwave shortwave. When the result is ready, submit it to the editor through the SHOW section above.

※ Prefill follows each builder’s query-string convention. Some may not auto-fill — paste the SIGNAL manually if so.
