I am interested in learning about what methods are currently considered to be the "best" for approximately solving large instances of the Traveling Salesman Problem (TSP) in practice. However, as I began writing a question concerning this I was prompted that The question you're asking appear...

I submitted an edit correcting a code bug in an answer to a popular and old question. A reviewer recommended to reject with reason: This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer. I'm confused as ...

So far there is no usage guidance for the tag lists. According Wikipedia, list may refer to an abstract data type, or a concrete data structure linked-list. So when should we use the tag lists? I thought it should be used only for the abstract data type meaning because there is already a lin...

I have a lot of difficulty telling whether or not I have selected a vote on CS stack exchange. The difficult is probably magnified by color blindness (Deuteranomaly, affects 5% of men). It's hard to establish whether or not the contrast is "too low" in an objective manner. In terms of brightne...

I noticed an issue: when I down voted an answer, my reputation also decreased by 1. I don't understand why? Please help me. Here's the screenshot:

In 2012, a question asked why is it that some professors teach C-style character arrays instead of C++ strings even in C++ classes. Now that Computer Science Educators is online, is it time to migrate this interesting question there, where it belongs?

Can I ask stuff like full forms of somethings in the computer science stack exchange, for example, the full form of Wi-Fi or internet? I won't really only ask this but some more also. So my question is can I ask full forms of computer related stuff?

This was already suggested in this 2012 question, with the top answer being to make software-verification the main tag. Maybe someone with 2500 rep can propose the synonym/merge? Or, answers arguing why they should not be merged would be welcome.

I was trying to (mod-)migrate a question here on meta.cs.SE to meta.SE. But what I got was this eclectic selection of possible targets: Note how most Metas are missing, meta.SE -- arguably the migration target -- is missing while arguably useless (for us) targets like Anime & Manga are ther...

Earlier discussions deemed parents useful, but not parenting. And the issue popped up again later. But until now, parenting was still in existence. Today, the last question with that tag was re-tagged. A tag not associated with any question is automatically deleted. In addition, parenting became...

In case parents is not specific enough, there are currently the following tags: 1) Female mother 2) Male dad fatherhood Only fatherhood currently has a tag info: Questions about being a father specifically, as opposed to a parent, where the gender of the parent is specifically relevan...

First of all, father is now present and, especially good news for the adherents of more traditional values, father is Master. There are, at the time of writing, still 11 questions tagged dad and 11 questions tagged fatherhood. The next step is to merge these tags, so that all questions are tagge...

Question : Is it possible to use tikzcd code in MO posts? There are information for drawing diagrams using AMScd $\require{AMScd}$ \begin{CD} A @>a>> B\\ @V b V V= @VV c V\\ C @>>d> D \end{CD} but could not find one for tikzcd I want to compile following tikz code. \begin{tikzcd}

Here I only ask questions and do not (can not answer for lack of knowledge) answer any of the questions. Sometimes I feel it is bad. Some questions that I know answer to are either closed as not research level or already has very good answers. What does MO community think about this? Is it a go...

I'd like to mention here two possibly related facts: (a) Soon after this question was answered, there was an arXiv paper posted providing the same answer (b) Soon after this closely related subsequent question was answered, the post was deleted by the OP. In this case, the answer was quite elab...

I've got a smattering of upvotes on my small number of answers but my reputation has never budged. Can someone explain why this is so?

I'm not sure why but it seems I've been targeted been down voting (I think by the same user) as it happened in all the questions I've asked in less than 60 seconds. I do not think this is due to the quality of the questions as they happened rather quickly? What should I do? I'm sorry if I've ac...

It is a very minor thing but still - it seems that answer texts have zero right margin which shows somehow unpleasantly with colored background of accepted answers: (This is with latest Chrome on Windows 10 x64) Do you agree that it would be better to increase it?

In a recent comment, one occurrence of stars-to-italics ('particular') doesn't render, but one does ('abstract'). This seems to be a bug. Is this the right place to report it? EDIT: Now also posted on Meta.SE. EDIT: Per @MartinSleziak's investigations below, it seems to be something about...

The question https://mathoverflow.net/questions/291518/mathematical-work-of-jonathan-gleason was deleted by some unknown person, not long after Jonathan Gleason passed away. I am shocked with the level of disrespect here. Can someone restore it?

On the one hand, I earned around 100-some points in the last day, on the other hand, my total increased by something like 10. Is there some bug?

Sometimes when a question is closed, different people have a different reason for closing it. You can see this while voting: there is a count in the margin saying how many votes of a given type have been recorded. However, once the question is closed, not all of this information is retained. Oft...

If there is an answer to a question that I have asked on MathOverflow or MathStackExchange which helps me to prove a result appropriate for a published paper, what should I do: (1) Cite the MO or MSE question as a bibliography item. (2) Mention the username of the one who answered my question i...

Guidelines to prove that $2^{\sqrt{2}}$ is a transcendental number? question bumped into https://mathoverflow.net/ after making an edit. I am not sure if that adds anything to the question. Should there be restriction on who edits a closed question? Even though if it is just tags. How about re...

I feel like, for some reason, I am not able to ask interesting questions here anymore. So it would probably be better to have my account closed. Still I asked some well-received questions in the past that might be of interest to some people, if any, so I would rather not see them deleted. Is the...

There is a symplectic tag on MO that currently contains just two questions. The first question so tagged dates from March 26 2017, so this makes this tag at least 1 year and 4 months old. I believe that this usage frequence shows that the tag is not really needed. I suggest to remove it and retag...

Sometimes there are questions about videos, movies, documentaries, etc. (I'll add a small sample below.) Would it be useful to have a separate tag for this topic? This could possibly help when searching for such questions. Or would such tag be too specific to be actually useful? Some of those ...

There is a tag called proofs. This tag has empty tag-info/usage guidance. Without any usage guidance it is quite likely to be used incorrectly. The fact that there are many deleted questions having this tag can be considered a supporting evidence of this fact. (According to SEDE there are 26 su...

My account says "we are no longer accepting questions from this account". Although some of my questions have been negatively received (and taking into account the fastidious nature of MathOverflow), I find it a little unbecoming to prevent someone from asking more questions. Is this site not...

Currently on mathoverflow, flags can be set for questions to be migrated to meta.mathoverflow, math.stackexchange, and stats.stackexchange. However, there are often questions that belong on other stackexchange sites, such as cstheory.stackexchange, cs.stackexchange, scicomp.stackexchange, or hsm....

I noticed when this question, How do these primes jump?, was bumped to the front page, the image I posted: https://i.stack.imgur.com/RGsqP.jpg will no longer load. Possibly my local problem?

This question of mine was made community wiki by someone other than me. I'm aware of discussion (e.g. here and here) arguing that big-list questions should be CW so that the voting system can be used to rank the answers without affecting the reputation of the posters. I suppose someone might ha...

This question was recently bumped to the home page, but is locked: Sound Request. Young Kids Talking to Parent As nothing can be done to the question, what's the point of it being bumped? Is this just a gap in the bumping logic?

What is our stance on questions on how to operate music production software and not directly on sound design? Are they on-topic or off-topic? Example: Subject: Is it possible to use the mouse scroll wheel to adjust parameters in Serum in FL Studio? Body: Is it possible to use the mouse ...

Why doesn't this site have MathJax activated? I've seen several questions and a few answers that are trying to use it, but it obviously isn't.

All - I created a sidewall-damage tag to specifically cover questions pertaining to sidewall damage. This will help us (and hopefully new users) find questions where their question might be answered and we can mark it as a duplicate if need be. We have a ton of questions on the site about sidewa...

I believe more viewers would be drawn to this site if you added modifications in the title. How is a decision like this made? Motor Vehicle Maintenance, Repair & Modifications. Are vehicle modifications within scope?

The tag wiki of apache tag states that, The Chevrolet Apache model is a truck which was released in 1958 However among the two questions in the tag, one question points to the Chevrolet Apache while the another points to TVS Apache. Should we create two tags chevrolet-apache and tvs-apache...

I am 100% in favor of a clear code of conduct for all online communities. I am largely in favor of the updated Code of Conduct for Stackexchange. I particular like the fact that it specifically calls out that this applies to mods just like anyone else. I'm also interested in what our community th...

Emacs is not a topic where many people have something to sell. So we don't get topical spam on this site. But as with any website that accepts external contributions, we get generic spam.

I changed a small piece of text in my previous question. The alteration is an important one and warrants a separate question. However, the system decides that I am posting the same question again and the button "Post your question" does not work. What to do? For the time being I appended a d...

I would like to type S-(left bracket)LEFT (right bracket) inserted as keyboard. How to escape the (bracket)? The problem is seen in question - How to type S-<LEFT> where LEFT for the time being is not enclosed in (brackets).

The tooltips in the Posts graph on the Meta Stack Exchange Site Analytics page are misplaced. Sometimes, they appear to be part of the next graph (see below) - the arrow indicates the point I was hovering over. This could be caused by the new responsive design; I've checked two other sites (As...

Steps to reproduce: Go to Site Analytics; the Posts graph (usually) opens in the daily view Click the 'Weekly' checkbox, the graph will immediately show the weekly view Refresh the page. The 'Weekly' checkbox will stay checked, but the graph switches back to daily view. Now, to go back to the w...

How is it possible for an answer to your question not to show up in your recent StackExchange inbox on the website , but only in your all items inbox: ? That is, the question I received "16 hours ago" is supposed to be inbetween the messages where the red arrow points in the first screensh...

There are a few main concerns I have: The answer rate is still low It feels like the community is less responsive these days There are lots of long-term unanswered questions (and loads of people don't mark answers as correct) If we're still in beta doesn't that leave our support support site at...

Because a product key or a Certificate of Authenticity was more common with old operating systems or software, the tag product-key would be a good key to add. The excerpt it could have: A product key helps prevent piracy of software. Use if you have a question about product keys and old OS's ...

There's a thread on BBC BASIC. One user posted an answer. I wanted to ask a question about this, and tried to use the @name tag to ping them. Most of the time when I do this a little tag pops up with the user's name. This time that did not happen. When I posted it, it does not appear it parsed i...

Usually the 'Annoying Robot' function posts new questions on 'The BBS', but there has been no anouncement of new questions since May 25th. Any reason to know about?

After reading Are x86 programming questions on-topic?, I thought about my first computer. It was an x86 Windows 98 machine. In fact, I still have it in my closet. I would consider this retro since it's very much unsupported by every hardware and software manufacturer involved in it. But, I think ...

I have a collection of old computers, some of which have modems and I want to try to connect them to the /r/retrobattlestations BBS: http://bbs.fozztexx.com/ I think it would be way more fun to have these machines actually dial in using their modems, but I do not have a phone line in my house (d...

I was curious about something I saw in an article about a historical computer, and while the problem has mathematical aspects, it seemed at the time that Retrocomputing SE was a better choice than Math SE or SO, so I asked here. What I've received so far includes what I'd call a "what's wrong wi...

Intel Itanium is probably more-or-less "legacy" now, like the z80 or m68k not what you expect to see inside a computer that's in current mainstream use. That's the impression I got. But it's rather recent, so I was wondering if my questions about it would be on-topic here or maybe better off on ...

It may be a good idea to refine the site, as I'm kind of unsure of the policy decisions you've made here (in meta), Consider filling out these two FAQ's (which is pretty routine on SE), https://retrocomputing.stackexchange.com/help/on-topic https://retrocomputing.stackexchange.com/help/dont-ask

Should 50s, 60s, 70s, 80s, etc. have their own tags? Personally I'm undecided but leaning towards no since things don't always break down cleanly by decade. What do y'all think?

It's been a long time. We need to get started on those faqs because it's way overdue. So how about this? Post an answer with some FAQ ideas. If it seems worth the effort, post a question-answer pair that will form the FAQ. Tag it faq-proposed and put a banner like this on the top so people don'...

Title says it all. Are questions about devices such as the new Commodore 64 Mini on topic here? It seems like an interesting device, but mainly seems to be a C-64 emulator running on an ARM chip. And while the keyboard is there for aesthetics (ie: doesn’t work) one can hook up a basic USB keyboa...

In most of my sub-exchanges, when I look at my profile the leftmost box has a graph of your rep changes. That box does not appear here in retro, instead there is a simpler box. Any reason why? I like the graph. I guess this is bug-like? UPDATE: added images... Here is the box in my SO account...

Oftentimes I come across an answer that reads something like On a related note, this other thing happened in the same decade on a completely different computer than the one you're asking about. or Yes and here's something else you might not know about assembly. So I'm definitely not w...

I'm not a Skeptics user, but I click through from the Hot Network Questions section on Stack Overflow. Twice now, that I can recall, I've come across a question where the following are all the case: The claim in question comes from a right-wing source Per what I believe to be a plain-English re...

Occasionally we get questions about whether a model or estimate proposed by an economist is accurate. Here are some examples: Do US Pharma firms have an incentive to develop useless cancer drugs? Do pricey medicines in the USA subsidise R&D for the rest of the world? Does corporate lobbying pr...

My recent question was received with mixed feelings: Why do children commit mass murder in their schools? It has a +3/-3 score, and it was even closed, reopened, and now has three new close votes. Before I spend effort to make it more acceptable to the community's palate, I want to narrow down...

So I posted this question on the Security SE site: “Are PS/2 devices a risky piece of hardware for modern point of sale devices to be using?” I wrote that late triggered by this question here on Super User where it seems like the creator of TempleOS blames the development of the OS cannot pro...

In the UK there are laws that required attendance at school in which non-attendance can result in parents can get fined for missing a day of school. My assumption is that these laws are in place to improve truancy and hence improve educational outcomes. So far I have not been able to find any d...

I hate posting meta things like this because I honestly doubt it changes much, but I just want to bring Oddthinking’s behavior on a question I posted nothing short of bullying behavior on a part of a moderator. The question in question is this one: In 1982 did then President Ronald Reagan send ...

Earlier today a number of old questions have been brought up again by a user called EDtreatment. The questions A, B and C all relate to erectile dysfunction as does his user name and user profile. This seems like a spam profile promoting a site although his answer were not spam answers. I have a ...

Many people get their facts from this site. Many people also do not do properly read and understand the answers they read, but merely mindlessly look at the upvote count and figure it must be true.

I want to ask a question about skeptics, but not about a specific claim. Is that allowed?

Diamond moderators regularly delete answers on the grounds that they are unreferenced. (Ironically enough, I can find a FAQ stating that answers must be referenced, but couldn't find any post saying that unreferenced answers get deleted) However, in the help section for trusted users, it says: ...

(Making this a separate post on suggestion from Sklivvz) I have an issue with the "No Theoretical Answers" rule, because in its present wording, if I for instance refer to gravity and hinge my answer on that gravity exists, and that the theory of gravity is accurate, then the post will be delet...

Currently almost everything a celebrity says qualifies as notable here. The only exceptions that I've seen applied (until yesterday) are: what a celebrity says in fiction (e.g. in a magician's show or in a comedy show [contextual]) or says with a disclaimer that what [s]he is not being rigorou...

Currently we have the tags young-earth-creationism and intelligent-design. The questions aren’t used for questions that are about those movements, but to categorise claims that are made by those movements. Should we get rid of these tags as per the logic of [donald-trump], you're fired! ?

In Neil Armstrong: “One small step for man” or “one small step for a man”? I posted an answer stating Whether he was meant to say "a man" or not, he definitely said "That's one small step for man, one giant leap for mankind." There was no static masking an 'a' https://www.youtu...

A notable Fringe Science researcher, using his purported m4d 1337 math, astronomy, and geography skillz, published a claim back in the 1990's predicting that there would be an astronomical alignment with a historical site during a specific time range in the future that had only ever happened once...

I noticed today a question, which was only lightly edited by a mod, so apparently there was nothing blatantly wrong with it, but which to me seems to fit the following pattern: quote notable claim from some science publication (A) counter-oppose it an unquoted counter-claim as possibly the real...

Recently there has been an influx of new users coming to our site and posting answers that consist of one or two sentences and possibly a picture of some sort. Example answer: here Is there anything that can be done to help fix this problem? Many of them raise good points but the answers ...

A recent edit suggestion created a new tag: airforceone. I tried to improve the suggestion by using the dashes as they are the standard replacement for spaces, but I got this: Update: A more generic and thus of wider use tag head-of-state-transport has been created. Example of use is the ...

Does it just keep asking until five people agree or does it ask ten times to get five votes or what? This question doesn't answer it.

The question went through multiple close and low-quality reviews. Timeline of events: Asker can't find flaps lever Answer shows flap switch on the real plane (photo and manual) Another answer shows (?) a barely visible flap indicator in a 10-year old (?) add-on for FSX Asker clarifies they s...

Apparently we have a hypotheticals tag <😱>, which has been used 8 times. Most recently today. But aren't those questions opinion-based? Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opini...

I think they were created recently, and they are rarely (sometimes not) used, compared to the main 'airspace' tag. My thinking is, for example, if I tag a question with Class-C, Class-C is not the same everywhere. So what is the usefulness when a user decides to filter/search by [class-c-airsp...

According to the help center, resource finding is off-topic. So shouldn't 'where can I find API for x' questions also be off-topic? Likewise for 'is there API for x'? Should those posts linked above be historically locked / closed / something else? Those posts attract promotional/spam answers.

The question I want to ask pertains to who has the authority or can claim downed warbird wrecks that are still sitting in fields or are in the bottom of our world oceans, lakes, and seas.

I am interested in how many female pilots there are, so I wondering if that will be well received on the main site or not.

Suppose i added a question which i expected to get a lot of attention and plenty of answers, but the question ends up with very little views.

Despite previous meta posts, there seem not to be a consensus, but rather a split, on what to do with joke "answers". I am and have been very vocal in supporting the idea that jokes do not belong in the answer field, and for different resons, not last the fact that they can obscure the actual an...

I asked this question over on Travel.se asking why a plane could only be moved by its pilot, and received a comment saying it would probably be a better fit for this site. Would it be a better fit here, or is Travel.se appropriate for it? If you guys want it, I can flag it for migration to here.

This question was asked on the Aviation SE yesterday. While the question does contain a kernel of validity that makes it on-topic here (specifically, IMO, whether aircraft can be powered by alternative kerosene-like fuels), the asker seems to go almost out of their way to turn it into a stubborn ...

This question got voted as a duplicate of this other question. Both before and after closure it got edited to avoid being a duplicate. Despite the edits, people voted to keep it closed. I am obviously biased, having answered it (and that's why I have not used my reopen vote, being a mod it wou...

I created the new airbus-a220 tag, can we have the older existing cseries (x5) become a synonym of that?

I noticed that an answer was deleted from a question that I commented on (Why would a flight from North America to Asia sometimes fly over the Atlantic?, the deleted answer had some reference to Riemann geometry).

I am convinced that a separate tag text-objects or text-object-select is useful. Text objects can only be used in visual-mode or after an operator (:h text-objects). A possible misunderstanding can be the so-called text-object-motions. However, the description of the new tag should clarify this....
