:::::::: And I still think it would be a good idea for you to post to the Xenwiki Work Group about this meet/join swap, and its symbiology. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 19:01, 20 December 2021 (UTC)

::::::::: Douglas: I didn't see the above post. I think you are clearly trying to twist things into a picture whereby I am abusing some kind of authority to make unilateral changes to the page without going fielding community feedback. As I've noted several times, I did post it on Facebook to get feedback. I got some initial feedback, so I made some changes. Then you gave some feedback, so I made more changes. Then people on here gave feedback, so I made even more changes. The feedback was good and I incorporated it into a new version of the page. Now there is even more feedback and I'm sure there will be even more changes. For someone who is unilaterally abusing whatever authority you imagine me to have, I seem to be spending an awful lot of time fielding feedback and making changes on what was originally intended to be a minor edit.

::::::::: Lastly, the issue of my "user roles": is that they are set the way they are because the Wiki used to be hosted on Wikispaces. When that went down, Tyler reached out to me to see if we could migrate everything elsewhere before it collapsed. So we took it on ourselves to do that. While and my largest role was in the initial migration, the ongoing maintenance of the sysadmin stuff is really Tyler's thing, but I still contribute to occasional minor technical maintenance from time to time when I can. This is not something I really enjoyed doing, but I spent many hours doing all of it for free, or sometimes at personal cost, just to make sure the information was preserved. But none of this has anything to do with anything, because my ability to help install some new MediaWiki extension has no bearing on the contents of this article, and certainly it does not matter either way in whether or not I participate in a Discord server, and I think it's in poor taste to try to somehow use it against me to win a notation debate about the use of & vs &&.

:::::::::: (I'm including this introductory section in both of my replies here to make sure that you see it, and because it applies to both places.) Sheesh, Mike. Please take it a little easier on me. I hope I will eventually be able to convince you that I'm your friend. Tone can be hard to read on the internet. You frequently react to the things I write in a combative way that I think is uncalled for. I think I'm a pretty chill and nice guy who thinks highly of you and hopes you will come to enjoy my presence and contributions here one day. Perhaps we should have another video chat session soon to clear some things up.

:::::::::: I believe I made myself clear in the above that I appreciate the efforts that you ''have'' already made to solicit feedback on this change. But I will express it again: I recognize those efforts and applaud you for them. Thank you for checking in with folks on Facebook about these changes.

:::::::::: Beyond this, I have suggested some addition actions I thought were appropriate for you to take, namely, posting in the Facebook group specifically designed for that purpose, and finding some way to get feedback from Discord as well. Those suggestions still stand.

:::::::::: I will also take this opportunity to again express my gratitude to you for the role you've played in the creation and maintenance of this wiki. Thank you, a thousand times over. Without your efforts, countless people in our community, including myself, would be significantly less enlightened about this fascinating theory that we all share a love for.

:::::::::: I now feel like you're twisting my actions crazily far from reality:

:::::::::: 1) I never indicated that I expected anyone to use the Discord as a prerequisite to making changes on the wiki. When, per your request, I posted on the Xenwiki Work Group on Facebook to specifically voice my suggestion to the wider group, that people should consider getting feedback from Discord because it is such an active community, I specifically said that I did not expect anyone to join Discord, that it was not in any way meant as a guideline but merely a suggestion if you wanted to selfishly de-risk your own time investment in this sort of thing, it might be a good idea. Furthermore, I personally volunteered there to be the middle man and help anyone who wanted an agent on Discord to get feedback for them. What else could I possibly do on that front?

:::::::::: 2) The fact that you perceive this as a debate that one of us will win is telling. I do not see it that way at all. I can't understand how you could get that impression. All I'm asking is that you give people who care about this sufficient opportunity to add their voices to the discussion, so that in the end we can come up with the best solution, which may or may not be one that you or I suggest ourselves. Getting my way is not an end in itself. I just want what we end up with to be high quality, and fair. I hope that makes sense now. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 04:00, 24 December 2021 (UTC)

::::::::::: Oops, I said I wasn't going to respond to this, but I guess one fragment of this line somehow got through anyway (but dedented). So since it was already half-posted, what I said was in response to this: "I never indicated that I expected anyone to use the Discord as a prerequisite to making changes on the wiki," "I specifically said that I did not expect anyone to join Discord, that it was not in any way meant as a guideline" etc. If I read your earlier post, quoting from it directly and interpreting at face value, your stated position is that it is "standard protocol" to "go through" the Discord, that "the president shouldn't be above the law" with respect to this "standard protocol" and so on - these are all the exact words you used, it's pretty strong language that can't be interpreted in any other way I can see, and what I took offense to. Beyond that, I've spent I don't know how many hours fielding feedback from you and others weighing on it and given you all the changes you wanted.

::::: I totally agree with Sintel. That's how I've always thought of it. I've never seen "&" used for the join of monzos. Can anyone point to some places on the wiki where it's used that way? In any case, what would be the harm in swapping those to "|" as in Sintel's and my scheme. Has "|" been used previously in a way that would conflict. So I'm supporting "&" for val-join, "|" for comma-join and subgroup-join. Then "&" is temperament join and "|" is temperament meet. Then "12 & 19" can be reads as vals or as temperaments, "&" works either way. [[User:Dave Keenan|Dave Keenan]] ([[User talk:Dave Keenan|talk]]) 09:06, 23 December 2021 (UTC) Dave Keenan

:::::: I agree with Dave and Sintel's proposal, at least as far as making it so that & is a concatenation (and reduction) of maps (meaning an intersection of commas and subspaces) and | is a concatenation (and reduction) of commas and subspaces (meaning an intersection of maps). I'm not concerned about which one is which, being called "meet" or "join" anymore. If I had clearly realized it was as simple as this earlier, i.e. that the only thing standing in the way of this simple of a solution was dismissing the use of & for concatenating commas as Mike claims has been done historically, I would have pushed for it. So I echo Dave's request for specific evidence of this usage, but more importantly his request for clarification on what the problem would be (if any) in changing them to use |. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 15:26, 23 December 2021 (UTC)

::::::: Douglas: Sorry, but I'm not going to waste endless hours somehow trying to search Facebook for posts of the form "ratio & ratio." I don't even know if that kind of thing is possible given Facebook's limited search feature, and if the primary reason you want me to do so is to because you demand "evidence" are unwilling to take my word for it, then I think there's no point in discussing anything further. Much like you don't intend to call a "map" a "val," I also don't intend to never use the phrase "81/80 & 64/63" ever again, but if it makes you happy, I have added & and | to the page as the predominant convention.

I think I'm a pretty chill and nice guy who thinks highly of you and hopes you will come to enjoy my presence and contributions here one day. Perhaps we should have another video chat session soon to clear some things up.

:::::::: I can see that I wrote things in a rather matter-of-fact, not sugar-coated way, but I didn't mean to come across "demanding" evidence, and I see nothing in the words I chose that suggest I was writing in an aggressive, "demanding" type way. I hope it's clear that in order to make the best decision we can make here, it would help the community here to have some further information, specifically about the extent of this usage you've described. I was merely seeking to gauge the extent of the situation: ''how common'' is this. It seemed quite likely to me that you could produce an extensive body of work with this usage, in which case I would seriously reconsider my position.

:::::::: Also, I didn't mean to come across like I didn't believe you. I very much believe you, and I don't see any words I wrote that indicate otherwise.

:::::::: It seems like the usage you describe is somewhat extensive (at least your subgroup temperament page, https://en.xen.wiki/w/Subgroup_Temperament_Families,_Relationships,_and_Genes, as you mentioned on Facebook), but apparently not extensive enough to completely problematize our proposal. So it does make me happy that you have added & and | to the page as the predominant convention. Thank you for doing that. All my best. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 04:00, 24 December 2021 (UTC)

::::::::: The feeling about combativeness is certainly mutual. Thanks for your assessment that I didn't use & enough to problematize your proposal. I'm not going to respond to the other post. [[User:Mike Battaglia|Mike Battaglia]] ([[User talk:Mike Battaglia|talk]]) 07:08, 24 December 2021 (UTC)

:::::::::: I just stated that I'm not intending to be combative. You've here chosen to implicitly reject believing me about that, and furthermore, recognize that you ''are'' behaving combatively. And you say these things in a snide way. So, I'll say this explicitly: I wish you would not act combatively with me in the future, and also behave friendlily.

:::::::::: This wasn't my proposal, if you recall; It was Sintel's, and he persuaded me and Dave with his strong, well-presented ideas. You're clearly thanking me sarcastically here, but I can't understand why you would be upset that we successfully identified that the scope of a potential obstacle to this proposal was limited enough so as not to problematize it, and therefore we had a good solution to this pedagogical issue. I know that of the four of us discussing here, this solution poses the greatest inconvenience to you, and and I can see that I haven't sufficiently expressed my sympathy and gratitude that you're taking this one for the team. So: thank you for your sacrifice here. I appreciate it.

:::::::::: I'll just go ahead and reply to your other comment here so we don't have multiple threads going on at once.

:::::::::: The fact that you're spent your time quibbling about the strength of the language I used at one point or another to recommend that you get input from the community in the ways it has specifically positioned itself to invite such input, rather than just actually getting this feedback, indicates to me that really don't really respect me or the community or care if we end up with the best results for everyone here. You just have your own inflexible ideas about exactly which and how much feedback is appropriate.

:::::::::: You also ignored all the stuff I said about collaboration and tone and friendship, etc. so this suggests to me that have no intention to behave more friendlily toward me. I hope that's not the case.

:::::::::: I think it would be best for me to excuse myself from this conversation at this point. Feel free to say whatever you want to say to clarify things on your end, but I don't think I have anything more to say at this time. Thanks again for your contributions to this topic. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 14:13, 24 December 2021 (UTC)

::::::::::: Of course I certainly never ''intended'' to be combative and apologize if anything came off this way. What I am saying is that the the feeling on most of these is mutual: many of the things you have accused me of doing are things I also feel you have done to me, such as misinterpreting my tone, quibbling over language, and generally being very harsh and unfriendly in the things you write sometimes. I am sure none of this was intentional for either of us and we both do our best; this is simply my feeling as it is yours.

::::::::::: If you want me to respond point by point I will, as some of the things you have just written are I think quite hurtful, but I don't know if it would do any good. I will instead just say that I respect you and the community a great deal, which is why I have spent so much time listening to your feedback and changing things the way you want. The only "inflexibility" here is that there are only 24 hours in a day and I don't have any of those hours available to put into participating in the Discord. Anyway, I hope you understand and would also like to move past this. [[User:Mike Battaglia|Mike Battaglia]] ([[User talk:Mike Battaglia|talk]]) 19:16, 24 December 2021 (UTC)

:::::::::::: I said I wasn't going to respond, but this comment of yours deserves one. Thanks for being the bigger person here, being kind, and extending an olive branch. Your assertions are very fair. I have misinterpreted your tone on many occasions. I have quibbled over language on many occasions. I haven't ''tried'' to be harsh or unfriendly, but if that's how I've come across, then I've got some stuff to work on. I'm certainly no master of self-awareness. I know I get angry and upset and I think sometimes even when I put on my politeness cap, it still bleeds out. You're a smart guy and you can pick up on how I really feel even if I'm trying to control it. I don't think it would do us good to analyze to death everything wrong we've said to each other here, point by point. I agree to let this one go and will try to start the next discussion off on a better foot. Thanks again for all your help on this and countless other things this year. Happy holidays. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 19:38, 24 December 2021 (UTC)

== Duality ==

Is there a proof somewhere of the duality, ie that join on kernel <=> meet on map? (And vice versa)

I'm convinced this is true, but it is not obvious at all.

- [[User:Sintel|Sintel]] ([[User talk:Sintel|talk]]) 13:51, 23 December 2021 (UTC)

: It follows from the basic properties of matrix multiplication. If you have two row vectors v and w, then the null space of the concatenated matrix [v;w] is defined as those vectors mapping to (0,0), which means any such vector needs to map to 0 for both v and w. [[User:Mike Battaglia|Mike Battaglia]] ([[User talk:Mike Battaglia|talk]]) 07:38, 24 December 2021 (UTC)

== Link back to new Temperament merging page ==

I've added a new page [[Temperament merging]] that attempts to give a plainer language, more pragmatic take on some concepts that are discussed on this page, supplemented with diagrams and examples. This new page is directed toward a general audience — readers with less mathematical background, but who still want to understand this topic well enough to do something with it. The first line of it links here: "This page gives a general introduction to this concept; for a more mathematical take on this, see [[Meet and join]]."

I'm writing here because I think it'd be great if the Meet and join page returned the favor, linking back to the new Temperament merging page, perhaps also as its first line, something like "This page gives a more mathematical approach to this topic; for a simpler introduction, see [[Temperament merging]]."

If there is agreement, I will not be able to do it myself, because I don't have sufficient privileges to modify this page, since it has been recently restricted.

This pattern of linking via the first lines between the pairs of general and mathematical takes on the same topic is fairly common, by the way. You can find it with [[comma basis]] and [[dual list]], [[mapping]] and [[temperament mapping matrices]], or [[monzo]] and [[monzos and interval space]], for examples.

Anyway, the ink is still quite wet on the new page, so constructive criticism is very welcome there. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 20:07, 9 January 2022 (UTC)

I've just remembered that at the bottom of the page, there's a See Also section that links to the ampersand operator page which has since been turned into a redirect page to Temperament merging. So if this change is made, that link should be removed, as it'd just be duplicating things. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:40, 11 January 2022 (UTC)

== OM should be Om ==

Per discussion here: [[Talk:Trivial_temperament#OM]] it seems like "OM" should actually be capitalized as "Om", because it's a reference to a Hindu concept that is capitalized that way, and also it looks confusingly like two variables O and M being multiplied together. This is the only page besides the [[Trivial temperament]] page where it is used currently. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 20:11, 9 January 2022 (UTC)

Also, it's unclear to me why the majority (but not all) of the occurrences of "OM" on this page have the subscript "G". It seems like they can all simply be "Om". --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:40, 11 January 2022 (UTC)

== <1/1> would be better than <1> ==

The <...> notation is interesting. But I think it would be clearer if <1/1> was used rather than <1>, to make it clear that this is a frequency ratio, like how you have <225/224> etc., as opposed to logarithmic pitch space where it would be a <0> instead. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:57, 11 January 2022 (UTC)

== Mismatched bracket count ==

It looks like in one of the examples at the end, for Meantone & Magic, we've got four angle brackets on the left but only two closing brackets on the right. I think it should be four on both sides. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:58, 11 January 2022 (UTC)

And you say these things in a snide way. So, I'll say this explicitly: I wish you would not act combatively with me in the future, and also behave friendlily.
+:::::::::: This wasn't my proposal, if you recall; It was Sintel's, and he persuaded me and Dave with his strong, well-presented ideas. You're clearly thanking me sarcastically here, but I can't understand why you would be upset that we successfully identified that the scope of a potential obstacle to this proposal was limited enough so as not to problematize it, and therefore we had a good solution to this pedagogical issue. I know that of the four of us discussing here, this solution poses the greatest inconvenience to you, and and I can see that I haven't sufficiently expressed my sympathy and gratitude that you're taking this one for the team. So: thank you for your sacrifice here. I appreciate it.
+:::::::::: I'll just go ahead and reply to your other comment here so we don't have multiple threads going on at once.
+:::::::::: The fact that you're spent your time quibbling about the strength of the language I used at one point or another to recommend that you get input from the community in the ways it has specifically positioned itself to invite such input, rather than just actually getting this feedback, indicates to me that really don't really respect me or the community or care if we end up with the best results for everyone here. You just have your own inflexible ideas about exactly which and how much feedback is appropriate.
+:::::::::: You also ignored all the stuff I said about collaboration and tone and friendship, etc. so this suggests to me that have no intention to behave more friendlily toward me. I hope that's not the case.
+:::::::::: I think it would be best for me to excuse myself from this conversation at this point. Feel free to say whatever you want to say to clarify things on your end, but I don't think I have anything more to say at this time. Thanks again for your contributions to this topic. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 14:13, 24 December 2021 (UTC)
+::::::::::: Of course I certainly never ''intended'' to be combative and apologize if anything came off this way. What I am saying is that the the feeling on most of these is mutual: many of the things you have accused me of doing are things I also feel you have done to me, such as misinterpreting my tone, quibbling over language, and generally being very harsh and unfriendly in the things you write sometimes. I am sure none of this was intentional for either of us and we both do our best; this is simply my feeling as it is yours.
+::::::::::: If you want me to respond point by point I will, as some of the things you have just written are I think quite hurtful, but I don't know if it would do any good. I will instead just say that I respect you and the community a great deal, which is why I have spent so much time listening to your feedback and changing things the way you want. The only "inflexibility" here is that there are only 24 hours in a day and I don't have any of those hours available to put into participating in the Discord. Anyway, I hope you understand and would also like to move past this. [[User:Mike Battaglia|Mike Battaglia]] ([[User talk:Mike Battaglia|talk]]) 19:16, 24 December 2021 (UTC)
+:::::::::::: I said I wasn't going to respond, but this comment of yours deserves one. Thanks for being the bigger person here, being kind, and extending an olive branch. Your assertions are very fair. I have misinterpreted your tone on many occasions. I have quibbled over language on many occasions. I haven't ''tried'' to be harsh or unfriendly, but if that's how I've come across, then I've got some stuff to work on. I'm certainly no master of self-awareness. I know I get angry and upset and I think sometimes even when I put on my politeness cap, it still bleeds out. You're a smart guy and you can pick up on how I really feel even if I'm trying to control it. I don't think it would do us good to analyze to death everything wrong we've said to each other here, point by point. I agree to let this one go and will try to start the next discussion off on a better foot. Thanks again for all your help on this and countless other things this year. Happy holidays. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 19:38, 24 December 2021 (UTC)

+== Duality ==
+Is there a proof somewhere of the duality, ie that join on kernel <=> meet on map? (And vice versa)
+I'm convinced this is true, but it is not obvious at all.

+: It follows from the basic properties of matrix multiplication. If you have two row vectors v and w, then the null space of the concatenated matrix [v;w] is defined as those vectors mapping to (0,0), which means any such vector needs to map to 0 for both v and w.

+== Link back to new Temperament merging page ==
+I've added a new page [[Temperament merging]] that attempts to give a plainer language, more pragmatic take on some concepts that are discussed on this page, supplemented with diagrams and examples. This new page is directed toward a general audience — readers with less mathematical background, but who still want to understand this topic well enough to do something with it. The first line of it links here: "This page gives a general introduction to this concept; for a more mathematical take on this, see [[Meet and join]]."
+I'm writing here because I think it'd be great if the Meet and join page returned the favor, linking back to the new Temperament merging page, perhaps also as its first line, something like "This page gives a more mathematical approach to this topic; for a simpler introduction, see [[Temperament merging]]."
+If there is agreement, I will not be able to do it myself, because I don't have sufficient privileges to modify this page, since it has been recently restricted.
+This pattern of linking via the first lines between the pairs of general and mathematical takes on the same topic is fairly common, by the way. You can find it with [[comma basis]] and [[dual list]], [[mapping]] and [[temperament mapping matrices]], or [[monzo]] and [[monzos and interval space]], for examples.
+Anyway, the ink is still quite wet on the new page, so constructive criticism is very welcome there. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 20:07, 9 January 2022 (UTC)
+I've just remembered that at the bottom of the page, there's a See Also section that links to the ampersand operator page which has since been turned into a redirect page to Temperament merging. So if this change is made, that link should be removed, as it'd just be duplicating things. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:40, 11 January 2022 (UTC)
+== OM should be Om ==
+Per discussion here: [[Talk:Trivial_temperament#OM]] it seems like "OM" should actually be capitalized as "Om", because it's a reference to a Hindu concept that is capitalized that way, and also it looks confusingly like two variables O and M being multiplied together. This is the only page besides the [[Trivial temperament]] page where it is used currently. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 20:11, 9 January 2022 (UTC)
+Also, it's unclear to me why the majority (but not all) of the occurrences of "OM" on this page have the subscript "G". It seems like they can all simply be "Om". --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:40, 11 January 2022 (UTC)
+== <1/1> would be better than <1> ==
+The <...> notation is interesting. But I think it would be clearer if <1/1> was used rather than <1>, to make it clear that this is a frequency ratio, like how you have <225/224> etc., as opposed to logarithmic pitch space where it would be a <0> instead. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:57, 11 January 2022 (UTC)
+== Mismatched bracket count ==
+It looks like in one of the examples at the end, for Meantone & Magic, we've got four angle brackets on the left but only two closing brackets on the right. I think it should be four on both sides. --[[User:Cmloegcmluin|Cmloegcmluin]] ([[User talk:Cmloegcmluin|talk]]) 06:58, 11 January 2022 (UTC)
