needs more focus

I think this needs more context ? Does anyone disagree ?

@MartinSleziak Seems good yeah

which is a good duplicate target for this post ?

please help close this unfocused request: "Teach me how to approach these kind of problems systematically."

[tage:duplicate] I vote to close this duplicate.

@Xander Could you help with my comment flags on my last request here?

@OliverDíaz Jose dupe hammered it closed.

@SimplyBeautifulArt Thanks for the response. (And for voting to close as a duplicate..)

@amWhy I don't see any comment flags in the queue.

@XanderHenderson :P but there's another "no longer needed". Mind you, I've tolerated being referenced as a "he", and now a "dude". But flagging is the best option. Thanks, btw.

@Xander Did you forget "winks"? Perhaps they were handled by another?

@amWhy They must have been handled by someone else. Or I handled them before I saw your comment here.

Though I think I would remember someone calling you a dude.

To be fair, I used to live in SoCal, so everyone is "dude" (or, if I am trying to be funny, "bruh").

Oh, there are flags now.

@XanderHenderson Thanks, all the same. Yeah, the evolution of "bruh" from "bro" Can there be a "sih"?

@amWhy Dude, bro, bruh, brah, broheim...

@XanderHenderson As in "burn your brah?" :D

To most folk from costal SoCal, "dude" is super gender neutral (though the others are not). It is hard for us to move out to the rest of the country and have to deal with the fact that not everyone knows that "dude" isn't supposed to be gendered. :D

@amWhy Dude! Don't do that! He doesn't deserve it!

(though you are more than welcome to burn your bra, if that is your desire).

@XanderHenderson I remember, maybe 20 years ago, when "dudette" was an option for woman. But I'm guessing that's archaic now!

@amWhy Yeah, I haven't heard that since the original TMNT cartoon.

We need a good, non-gendered "dude" in English. :D

@XanderHenderson Indeed! And other then "guys", too.

@amWhy Again, "guy" is a term that has been gender-neutral everywhere I can remember living. I know that, historically, it hasn't always been seen that way, and that a lot of people regard it as gendered, but it is hard for me to wrap my head around that.

I think it is somewhat generational.

People younger than myself seem to have no problem with a gender-neutral "guy", while people older than myself seem to regard it a masculine. I feel cuspy.

@XanderHenderson Thanks!

@XanderHenderson I'm "cuspy", as well. But at the same time, knowing it's origins, arguing that words like "he", "guy", "dude" are supposed to apply to all others, and therefore, shame on all of those who object, is an old old old tactic to dismiss objections due to the fact than none of them are gender neutral.

@amWhy I think that there needs to be a conversation which goes both ways. When someone says "hey, don't call me dude", you should respect that.

On the other hand, when someone says, "hey, I grew up on a culture where dude is non-gendered, and I have a hard time not using it in my daily vocabulary", one should show a little grace to that person. Intent matters.

And some of us women, are sick of being ridiculed when we object.

On the third hand, there are @$$hats who will say "DUDE IS NON-GENDERED! GET OVER IT, SNOWFLAKE." Those people can be shunned and ignored.

@XanderHenderson Absolutely.

@XanderHenderson Indeed.

I remember quite well, the difficulty in picking up "singular they". It grated against my grammarian instincts, but have since, embraced it as a means to talk about one person, generically, or refer to a person, say online, when one's name isn't decisive, or else clarified elsewhere their preference.

@amWhy What is weird about the singular they is that it has been around for 700 years.

Every century or two, some prescriptivist gets a bug up their butt about singular they, but it has been part of English since, like, forever. :/

Fun fact: singular "they" and singular "you" are about the same age.

We managed to do away with thees and thous, but can't seem to get rid of hes and shes.

@XanderHenderson With me, when I referred to "grammarian instincts", it meant, what is expected in SATs/ACTs, and GREs!!

Oh, I figured as much.

@XanderHenderson And at age 14, I undertook the rewriting of the Bill of Rights to make in non-gendered. Took quite some time, apart from other assigned coursework!

This is nonsense, right: math.stackexchange.com/a/4593471?

@XanderHenderson Indeed it is. I was a delete vote, until I tried to vote to delete, but ended up retracting my vote! Shot myself in the foot.

Please consider voting to delete this incorrect answer.

@Xander it's gone.

@Goku It's been closed!

For those with spare close votes yet today: this post needs to be closed

@amWhy thank you.

@Goku Thank you, too!

close I vote for closing this duplicate There are solutions based on the duality of $L_p$'s spaces already.

delete duplicate 1, duplicated 2. These problems are all variations of translations and dilations in geometric series and had been posted in MSE many times before.
