Personally, I don't expect any of related issues to be resolved any time soon. I think another new thread is unlikely to help.dvgrn wrote: ↑August 24th, 2023, 2:23 pmI've heard from a few people now that they don't see the point of posting their opinions on any of the currently open threads on the "signal" topic -- just because it's obvious to them that their opinions would get promptly drowned out by what amount to copy/pasted restatements of either my opinion or yours.
On the other hand, the recent "poll" thread on the definition of "dependent reflector" actually got some attention, to the point where it might well be considered to be a statistically significant expression of community opinion.
So that seems like it might be an idea for making some progress on the "signal" question. What do you think of starting a poll thread to collect community sentiment, using a short summary of your proposal and my proposal?
The poll thread did not give any definite conclusion, other than that there are already at least several votes from people on either side. I'll quote here the latest post in the poll thread:
For what it's worth, there are already several places where the relevant discussion was or is happening:
- several posts in Oscillator Discussion Thread, where dvgrn wrote:

However, there isn't actually any kind of signal loop at all in these things -- it's two or four separate segments. So any use of "loop" seems like not such a good idea. You wouldn't call something like this a "glider loop", right? The "signals" are traveling much faster than lightspeed through the gun, and therefore they're not actually signals:

Looking at it all again, I think that there actually are perfectly viable signals in a dependent reflector loop, and that there is an unambiguous way to decide which output glider corresponds to which input glider, and that (completely contradicting what I said above!) there's no problem with super-lightspeed "signal" travel, if you pick the right correspondence.

By the existing definition in the LifeWiki entry signal, phrases like "a signal has a line of symmetry" are meaningless. A signal is information carried by a moving object. The moving object may or may not be symmetric.dvgrn wrote: ↑August 24th, 2023, 2:23 pmIf "signal" is only allowed to mean "confocaloid-signal", then we can't say things like "... when the input signal has a horizontal line of symmetry ...". But if the definition of "signal" includes dvgrn-signals, then the meaning of that phrase remains perfectly clear, and then might not be any particular reason to change the wording.
My preference is to keep the existing definition of signal, and to fix unnecessarily ambiguous wording in other LifeWiki entries.
I don't know how much work it would be to do the same for Life Lexicon. That might be a different case, because LifeWiki can be edited by multiple people.
I think 'signal' should not be used to mean 'active object' on LifeWiki. Active objects should be described as active objects.dvgrn wrote: ↑August 24th, 2023, 2:23 pmNow, if we could settle the issue of whether "signal" can be safely used on the LifeWiki to mean "active object moving through signal circuitry", then I think I wouldn't have to be so worried about the removal of "signal" from a few places where maybe it's not strictly needed. I totally agree that there are some definitions where "signal" is a little bit redundant.
I do not consider 'signal circuitry' to be a useful phrase. Just because a folder in Golly's pattern collection is named 'Signal-Circuitry', does not mean it is a meaningful category. It would be clearer to write 'circuitry' or 'reusable circuitry', depending on the intended meaning.
