Matt Thomas wrote: So I said to myself "Oh it links to math.meta. This interesting thing on the right must be something from meta that's being promoted. Neat! Maybe there's some interesting discussion happening on meta that I'd like to participate in!" You thought correctly! The use of "ads" in the URL is an abbreviation for Community Promotion Ads, ...

This is a great idea. Some implementations are written in just a few lines of code in Python/MATLAB/Mathematica. One can share the code using a pair of ` around the code without much distraction: # insert my code # here If it is done in desmos, a snapshot may be more appropriate. For scripts that are long, I agree that "It'd be nice to have ...

For what it's worth, I took the SEDE query posted earlier in the comments and tweaked it to generate some statistics on the historical effectiveness of the proposed autofilter. Specifically, my query returns a monthly count of: the total number of questions selected for HNQ in that month, the number of those questions that were either closed or manually ...

At least in theory, the meta posts that discuss recurring and relevant issues are tagged faq (there is a also faq-proposed as a precursor). In practice, we might not be consistent enough with this, yet still I think that some of the relevant stuff can be located via this tag (or these two tags). Indeed, two of the three posts you mention are tagged with ...

I haven't logged into this site for some time, but I felt I needed to to register my displeasure if our community indeed marches further down this route. This might not come as a surprise, given my last meta question: Under what criteria should we remove questions from the HNQ list? Let me start by stating that the goal is to filter out bad titles. If it ...

While I think there is some "standard" (ISO maybe) that recommends this, in my experience this is rather rarely done in mathematics, and (or therefore) many will find this usage rather unusual. If you prefer this style I will not edit your posts and would tell others to leave your posts alone, but please do not change this in others' posts, not even when ...

For the current case: I merged the old version into the new one, thus preserving the initial answer. It seems that the user asking, who is very new, reacted to feedback and did this rather well. Only, they deleted and reposted rather than editing. I explained them now how they should proceed. For the general point, as you might know, for users with more ...

If you truly think the question does not fit in on math.se and would be a perfect fit for scicomp.se, you can flag about it, but this occurs infrequently enough on math.se that including it in the related sites would not be practical. There are a number of other sites which we also don't include in the related list for the same reason.

It would appear that it is not: Introducing Dark Mode (beta) for Stack Overflow. There are a lot of challenges to implementing dark mode across a platform like ours. We are among the 40 largest websites in the world in terms of monthly unique visitors. We also have hundreds of communities with different design aesthetics. On top of our public Q&A ...

EDIT: Originally I suggested using SEDE (see below). But probably a better option is to use some tool getting data about the usernames from Stack Exchange API, such as the one mentioned in the comments. (It is also mentioned in some other places - on this meta: To whom am I replying?, on Meta Stack Exchange: Make the “past names” list public info for 30 days ...

The point regarding the "unanswered" queue is a good one. It is indeed not ideal if questions appear as "answered" yet only have a partial answer. However, considering the cost versus the benefit I think it is not likely that this will be implemented. Here, by cost I do not only mean the actual cost in developer-time but also the cost of added complexity ...

I don't know if a bot is needed, but I did write a query on the SE Data Explorer that finds links to deleted posts on other SE sites. As the screenshot shows, there were 343 such broken links on math.SE as of last weekend's SEDE update. I've fixed about a dozen of them since then, but they'll still show up in the results until the next weekly update. The ...

Regarding your questions: There is no dedicated feature to see how many users are online (but see Martin's comment for some ideas); it is also not exactly clear to me what it would mean. Generally, the site is more designed as an asynchronous medium, not for real-time or near real-time interaction. The follow feature is very new. As far as I know such a ...

The answer to the main Meta post of Why can I not edit a self-deleted question? says the restriction is just for self-deleted questions: Posts that are deleted, but not self-deleted can be edited without restriction. It also says the main reason for this restriction is to help prevent a form of abuse by spammers that is "very difficult for the system to ...

There is no intrinsic reasons why this is not possible; the app is just incomplete in this regard. I am not sure if intentionally or not, in any case it is known to the people in charge, yet as far as I know its development was stopped, so this is ultimately irrelevant as either way it will not change. Even on various mobile devices the site is quite ...

The numbers are not inappropriate. This is a standard font. You can change the font on your side, if you want to. Of course basically everybody else will still see it differently. Some instructions are here How to change all fonts on Stack Exchange sites? You should not use MathJax here for writing these numbers either. That is inappropriate. You should ...

Your question is marked as duplicate, but this might not be the reason why you are getting a down-vote. As pointed out in the comment, you have a net gain of reputation point, so in terms of reputation points, you are not being punished. Yes you cannot delete your post, not because it is marked as duplicate. You cannot do that since there are upvoted ...

Such things are supervised to the extent possible (it is not always possible though) and actions are taken (in the form of warnings or suspensions). However, even when we identify the source and take action the votes are not always reversed mostly for practical reasons. It is annoying and even a form of abuse, but the practical implications are fortunately ...

I am afraid this actually changed and the answer is that (at least currently) this is not possible. See 'Favorite Tags' is now 'Tag Watching' The option to subscribe is not supported anymore. Instead one will be able to chose to get notifications in ones inbox (not yet operational though!). It is still possible to get email notification ...

There seems to be an inherent tension between, on one hand, providing an ask-question wizard that will actually help homework askers with asking their question in a good way, and on the other hand not giving the impression that homework help is what MSE is for. The really good questions that we always want and need more are not about homework. They would be ...

Is it possible to add some sort of way of knowing which posts were affected by the user's removal? I've described a procedure for this on Meta Stack Exchange. It uses the Stack Exchange API but does not require programming. Go to this page Change the site with the  link (default is Stack Overflow) Click the 'Get Token' button so that the API knows it'...

Since the link in the accepted answer seems to be dead, here is a solution using SEDE. We're looking at comment replies used below posts by a given users and after comments by a given user. This is by no means foolproof, but usernames of the given user are certainly more likely to appear in such replies. Usernames used in possible comment replies to posts ...

When you've got enough reputation that you can see deleted content, type the following command into the search bar: [gap] deleted:yes. Searching for deleted content will only show content that you own, so you will immediately see your answers (and your questions if you asked any on the topic) and nothing more.

The underlying philosophy of the Stack Exchange Network is that it is a questions and answers site. The goal is to have a database of good questions with high quality answers. The questions and answers are primary---everything else on the site serves to improve the quality of the questions and answers. The intended use for comments is to request ...

Here is something close to what you wanted: $$\begin{array}{cc} & \begin{array}{ccccc} 1 & 2 & 3 & 4 & 5\\ \end{array} \\ A = & \left[ \begin{array}{ccccc} h & e & l & l & o \\ m & s & e & * & * \\ m & e & t & a & * \end{array} \right] \end{array}$$ I learned it from http://latex-...

For the purposes of reproduction, with the aim of avoiding cluttering the mathematical post with program code, and until the collapsible code markup finally arrives at Math.SE, you always have the option of hiding the code in a Markdown comment. After adding this comment you can also include the link to the Markdown source of your post for easy access. This ...

I'll try to address some issues I see here. First, there is an underlying tone of this being an interventionist approach and that opposition is out of principle against interventionism. That is fair, but if you are against interventionism out of principle and you think that such a list is an intervention, then you should be against the HNQ too. (A ...

Let me first answer the two questions directly: Is there any way to get aware of such a comment-deletion? There is no functionality on the site to get alerted to comment-deletions. You have to check. Likely, somebody could write a script to check automatically, but that's a bit orthogonal. Is there any way to reply a feedback comment such that the ...

The page How do I search? in the help center contains only advice on the built-in search. Maybe a link to meta could be included at the beginning (or near the beginning). Various ways to search this site (both using the built-in search and using some external tools) are summarized on meta: How to search on this site? The purpose of this answer is mainly ...

There are currently several SE sites that are closely related to Maths SE: MathOverflow (technically not an SE site) Mathematics Educators (Beta) History of Science and Mathematics (Beta) CrossValidated Computational Science Mathematica & Wolfram Language Physics Some may even list Stack Overflow here. etc. While they are supposed to be independent, ...
