TL,DR: me too. Posting a scan of the text in a textbook or worksheet is a low in laziness. (I'd say a new low but I've seen that before on SE.) That right there can justify a downvote. A scan of a figure can be ok, as long as it has accompanying text that explains the problem. For example, this is an appropriate question: the text in book reference says ...

Here's the policy I would favor. I'm open to being contradicted if you've had experiences on other sites (Theoretical Computer Science, Math, Physics, …) that show that this policy is not viable. Questions like “Is this proof correct?” or “I'm sure this proof is wrong but what's the fallacy?” or similar variants should be closed as “not a real question”, ...

I am strongly in favor of adopting the official stance of Stack Exchange, both because I agree with it (a good question doesn't need to be CW, and a bad question is not excused by CW; moderators can use their judgement in exceptional circumstances), and because I won't deviate from the official stance without having a good reason (i.e. if we should deviate, ...

Frankly, this is what teachers and teaching assistants are paid for. You can also ask peers or more advanced learners you trust. Reviewing material is generally a bad fit for this platform: it's a task that requires lots of reading (as opposed to a snappy, self-contained question) and has no clear-cut answers. You may also want to consider carefully if ...

I don’t think that in-depth reviews of whole articles (10 pages in this case) are in the scope of CS.SE. If the author submits his work the usual publishing routine will perhaps produce some reviews. Now, if a third person has a question about such an article it should be specific and narrow. For example something along the lines: “The author has defined X, ...

I don't care what the authors say, I will not refrain answering a question because someone somewhere requested people not to answer this question. The text of the question belongs to the author of the book, and they may request that the text not be posted; in fact, that is automatically the case due to copyright law. The semantic content of the question ...

It's up to each poster to decide whether the question belongs on the site or not. If you think the question doesn't belong here, vote to close. If you think the question belongs here and you have an answer, post your answer. That others have answered should not influence you not to vote to close, and that others have voted to close should not influence you ...

The problem I see here is that LaTeX will not be parsed by most (all?) feed readers nor in the mobile apps. I have been annoyed regularly by LaTeX-heavy titles that are incomprehensible when not translated. Therefore, I propose that we strive to restrict use of LaTeX in titles to the absolute minimum. In this case, that means none.

I have never before (knowingly) participated in a beta, but this is what I have heard: Vote often & smart Apparently only relatively feq users have voted significantly often so far. We need to seed reputation so we have members with moderation privileges soon. Also, heavy voting encourages new members to participate and demonstrates that people care. Of ...

I'm starting to get really tired of seeing these "list question" discussions come up... "List question" covers a lot of not-very-related question types, and usually ends up confusing someone who sees the discussion and thinks, "But what if the answer to my question just happens to be... a list?" There is some very specific guidance in the FAQ on every site: ...

I think there are some natural questions that can only be answered appropriately by giving a list. Examples include Where to find recorded CS lectures online? Which books for X can be recommended? What should be in every CS graduate's toolbox? The proper way to have such questions on StackExchange is, imho, like this: There are few (at best only one) ...

As long as Patrick87 links the questions together, which he has, I think this is sufficient. Unless/until heap automata become a revolutionary new concept, it's a good idea to keep the tags as general as possible, so no [heap-automata] tag. Tags such as series etc do not make sense in isolation, outside of the specific question, so I don't see how they will ...

Your option three fits my opinion: Offer to migrate questions that would be on-topic on TCS if they have had no satisfying answer after a few days and the asker agrees. We have snatched badly-treated questions in scope overlaps from SO and math.SE, there is no reason why we should not act likewise in the other direction. Questions like this here are ...

This is a general answer. If someone is editing your question and you think they did it wrong, feel free to roll-back their changes. Most likely there was some misunderstanding going on. I would recommend the following to improve your question after the roll-back. Try to make your question clearer. Check what the editor had got wrong and why. Extend or ...

Some users ask a question and disappear. Maybe they found an answer elsewhere. Maybe they don't care anymore. Maybe they they lost the cookie to their account. There's nothing you can do about that. Users with less than 15 reputation cannot vote. Any user can accept an answer on a question they asked (except during the first 15 minutes). They are not under ...

I sympathize, and I understand how it can be demoralizing to put in a lot of effort into an answer only to never receive any reaction or feedback at all. It can feel like you are writing into a void, and that's not very motivating. I sympathize with the problem you've identified. Let me suggest a different way to address the problem. Rather than trying ...

First of all, if we would like to have a specific rule against such questions, I don't think it is useful to make the topic "P vs NP" part of that rule. I don't believe we are being flooded by questions about that topic and I don't think that that topic is inherently 'problematic', nor that it is within the domain of research. (That is, questions about the ...

List questions generally do not work well on Stack Exchange. They are generally banned on Stack Exchange: real questions have answers, not items or ideas or opinions. I happen to have direct experience with list questions, having active on Scifi.SE since day one and a moderator there for most of that time. This is our best list question, kept around for ...

I would say that recommendations for any reference material must involve computer science at some level and more importantly are focused from a computer science vantage point. I think the question referenced, in its current form, is not appropriate for this forum. It seems that the question referenced needs to be refocused to ask "what level of biology ...

Here is another example where useful information is deleted by Gilles. (I was going to refer a user on cstheory to the answer posted here but I can't since it is deleted, and it took me considerable time to find even the deleted post.) Moreover since it is deleted by a moderator other users cannot vote to undelete it. Let me emphasis that this is not about ...

My first thought on this matter was: this is a computer science site, so questions and answers should to some extent adhere to the scientific method. For answers, that means they should make only falsifiable claims and back them with solid evidence, which can be a (good) reference, (significant) empirical data or a (clear) formal proof (idea). Any answer ...

As blufox said, the specific question does not ask for a solution. But I think that you raised a good point apart from the specific question: should we follow a request by an author not to post solutions to exercises in a book on the web? Well, I do not have a solid opinion on the matter in general. Given that there are different reasonable opinions, I do ...

I would say that if anyone notices such a case (i.e a question which is an exercise from a book and the authors have specifically written that they're unhappy with solutions being posted online), then they should put this in a comment or edit the question to this effect. Then users who might want to answer can make an informed decision whether to go against ...

Rationale Do not prevent legitimate questions. Avoid bickering about what constitutes homework. Have grounds for closing obvious dumps of homework assignments that no one cares enough about to answer. Goal 1 implies a policy that is not overly restrictive: the asker is given the benefit of doubt. Goal 2 implies that the consequences of being considered ...

You do not directly lose reputation because you answered a question and the asker's account gets deleted. You only lose reputation in two cases: if the account that cast an upvote or an accept vote on your post gets deleted, or if your upvoted post gets deleted. If the account that cast a vote is removed, the vote is removed. This helps limit vote inflation ...

I am the author of the question, In this case, I did not ask for the solution. My problem was with the interpretation of the question which I felt was not clear. This is clear (I hope) from the line "However, this seems a dubious interchange of space and time. If on the other hand, t actually meant that the second machine stops within t space, too, then ...
