 * In the discussion you've linked to, they seem to adopt the meaning "signalling device with arms" as their definition of "semaphore".
 * I think it's fine for words to have different meanings in different contexts; but I find the definition adopted here to be startlingly broad. For example, per the definition the lede, a mirror/sunlight signalling device is definitely a semaphore, but so is the optical hookup between my CD and amp.
 * The citations for the definition given in the lede could be improved; one is Britannica, and the other is something called "FactMonster", which I've not observed anything on WP being cited-to before.
 * I came here to find out about the semaphore alphabet, so I guess I'm off to Flag semaphore. Ah, rabbit-hole -> Optical telegraph; they distinguish two types - a shutter telegraph (which by our definition is a semaphore) and a "semaphore telegraph" (one with arms).
 * So there's an implied definitional conflict between these articles. I don't know what to suggest, but I don't like leaving this kind of confusion lying around, without some kind of explnation.
 * That is, if there are diverse opinions about what a semaphore is, that is a fact that belongs in the article.

A tautology is a taugology
This interesting (?) sentence appears in this article: "A hydraulic telegraph is either of two different semaphore systems involving a hydraulic-telegraph." Once in the past, the article titled Traditional Brazilian medicine began by saying "Traditional Brazilian medicine is the traditional medicince of Brazil." Somehow this present instance doesn't seem as egregious but it probably merits an honorable mention. Michael Hardy (talk) 02:31, 20 February 2022 (UTC)

– I'm struggling to understand how this could be considered the primary topic of "semaphore". Semaphore (programming) gets twice as many page views and is at least as well represented (compared to all signaling device usage) in reliable sources such as those accessed via Google Scholar or Google Books. There are several other uses on the dab page that readers may well be looking for. (t &#183; c)  buidhe  17:18, 23 January 2024 (UTC) — Relisting. BilledMammal (talk) 01:11, 31 January 2024 (UTC)
 * Semaphore → Semaphore (apparatus)
 * Semaphore (disambiguation) → Semaphore
 * Support the programming meaning has 12,291 views compared with only 6,125[] for the apparatus meaning.  Crouch, Swale  ( talk ) 18:02, 23 January 2024 (UTC)


 * Oppose. My first job was as a computer programmer, and I've never heard of a semaphore in programming. Signalling is the only meaning my brain recognises. Dondervogel 2 (talk) 19:15, 23 January 2024 (UTC)
 * Oppose The signal is primary by longterm significance. The programming article even acknowledges the name is based on the signalling device. It's ridiculous to suggest that every little computer science term based on something from the real world should then dethrone it simply because it gets more views. Apple is still the fruit, by the way. ᴢxᴄᴠʙɴᴍ (ᴛ) 23:49, 23 January 2024 (UTC)

 * https://wikinav.toolforge.org/?language=en&title=Semaphore indicates that there were 244 clicks on the hatnote over a total incoming traffic of 7.4k and total identifiable outgoing clickstreams of 1.2k, which would be ~3% and ~20%. With the CS meaning being basically another derivation of the same broad concept as the physical meanings, at least to the untrained eye of the average reader, perhaps the best thing to do would be to actually give it a place in the same article as opposed to making readers search for it via the hatnote. --Joy (talk) 13:34, 24 January 2024 (UTC)
 * Oppose. Very clear primary topic by long-term significance. The average person would associate semaphore with this, not the programming term. -- Necrothesp (talk) 14:54, 6 February 2024 (UTC)
