If there's a low-quality-but-interesting question that attracted no answers during its lifetime, is there a way to re-ask it? The impression I get is that if such a question is closed, then a) it cannot be answered but also b) further questions with the same content are still considered duplicates of it.

Hello. I would like to ask a follow up question to this comment on a question that I asked on meta about an hour ago (math.meta.stackexchange.com/questions/35389/…). I don't want to put too much back-and-forth in the comments for the question. I hope it is acceptable to ask here instead.

Thanks. I logged out, which caused my unregistered account to disappear. I then signed up (I think?) and managed to create an area 51 account. I have 151 reputation, but my site-wide profile text was copied over to area 51, so I think that means my account was successfully linked. I didn't think to write down exactly what I did, but I did follow the instructions on the "you have 51/151 rep" question pretty closely.

I keep seeing Unable to log in: No user found. I tried contacting the stack exchange tech support. They were very helpful, but don't have tools for manipulating area 51 specifically.

Hello, all. My account is not properly associated with my area 51 account and I'm not sure how to fix it. Is there someone I can talk to prior to or shortly after the launch of the beta site?

I was proposing moving this question to the philosophy exchange (assuming that they're open to it) and rewriting the body of the question to be narrowly focused on a single connective for concreteness. You could focus on xor, for example. You can also explain that your broader question is why some definable connectives are easy to use at a meta-level and some aren't.

There's an interesting question here (why are some connectives apparently less common in ordinary mathematical reasoning?), but I think this question is more of a philosophical question than a mathematical one. I also think it would benefit from focusing on a single connective.

Hello. Thanks. I'm trying to give the new folks who ask logic questions decent advice. I learned a ton from the folks here who've answered my questions in that topic over the past two years or so.

A visual block with $ as a boundary seems like a magical kind of block.

Is there a way to do that? seems like a "jaggedness toggle" would do the trick.

wow. $ is visual block mode does the right thing and inserts text at the end of every line ... it doesn't just extend the right edge of the block to the end of the current line, thanks.

thanks.

but it does have another effect. namely that selecting a range of lines in visual line mode, switching to visual block mode, Appending some text and then hitting <esc> inserts text after the first column in the line. Switching from visual line mode to visual block mode doesn't extend the block rightward in a useful fashion.

oh I thought you said that visual line mode has no concept of which columns are currently being selected

@DJMcMayhem I think one of your earlier comments was right though. <c-v>A from visual line mode places you right after the first column. It's probably nontrivial to determine the length of the widest line in a range.

what I want to be able to do is select a region with visual line mode, but have it act like a visual block starting at column zero and extending to the end of the widest line when using I and A

Ah, that example was supposed to illustrate how using I/A in visual line mode doesn't allow you to put text at the beginning/end of a range of lines

Hi.

If the balls were indistinguishable, would there be zero left at midnight, infinitely many, or would the question be ill-posed?

Anti-pattern is a bit too harsh/judgmental, but a source code generator is a much heavier weight dependency than a library. Just imagine if you had three or more code generators in the same project or generators feeding into each other.
