For example, if you click , you will go automatically to the PDF file.  Is there any way to do this? Why would a static nested interface be used in Java? Complement of maximal multiplicative set is a prime ideal Let $R$ be a commutative ring with identity. I've been trying to prove the following:     If $S \subset R$ is a maximal multiplicative set, then $R \setminus S$ is a prime ideal of $R$.   I have spent some time in it, but nothing is coming to my mind. Any idea/solution will be appreciated. How does stuff glow in the dark? What is the relation between normal extension and separable extension? What is the relation between normal extension and separable extension? Let F be the algebraic extension of K, if F is a separable extension of K,if and only if F is a normal extension of K? is this correct? Are comments discouraged in a BibTeX file? biber complains about "junk" in what should be seen rather as commented-out lines in a BibTeX file.  I was wondering if comments are discouraged in BibTeX at all.  \documentclass {article}  \usepackage {filecontents}  \begin {filecontents} {ref.bib}  @book {book1,  author={author 1},  title={title 1}}   book {book2,  author={author 2},  title={title 2}}   @book {book3,  author={author 3},  title={title 3}} \end{filecontents}  \usepackage [backend=biber] {biblatex} \addbibresource {ref.bib}  \begin {document}   \nocite{*}  \printbibliography \end {document}   Here is biber's output:  INFO - This is Biber 2.1 INFO - Logfile is 'mwe.blg' INFO - Reading 'mwe.bcf' INFO - Using all citekeys in bib section 0 INFO - Processing section 0 INFO - Looking for bibtex format file 'ref.bib' for section 0 INFO - Decoding LaTeX character macros into UTF-8 INFO - Found BibTeX data source 'ref.bib' WARN - BibTeX subsystem: /tmp/No7MbpTruX/ref.bib_31209.utf8, line 13, warning: 43 characters of junk seen at toplevel INFO - Overriding locale 'en-US' defaults 'variable = shifted' with 'variable = non-ignorable' INFO - Overriding locale 'en-US' defaults 'normalization = NFD' with 'normalization = prenormalized' INFO - Sorting list 'nty' of type 'entry' with scheme 'nty' and locale 'en-US' INFO - No sort tailoring available for locale 'en-US' INFO - Writing 'mwe.bbl' with encoding 'ascii' INFO - Output to mwe.bbl INFO - WARNINGS: 1 System settings won't open on Ubuntu 20.04 LTS after adding System76/pop PPA I have an independent variable called "quality"; this variable has 3 modalities of response (bad quality; medium quality; high quality). I want to introduce this independent variable into my multiple linear regression. When I have a binary independent variable (dummy variable, I can code 0 / 1) it is easy to introduce it into a multiple linear regression model.  But with 3 modalities of response, I have tried to code this variable like this :  Bad quality      Medium quality      High quality       0                1                  0      1                0                  0      0                0                  1      0                1                  0   But there is a problem when I try to do my multiple linear regression: the modality Medium quality gives me NA:    Coefficients: (1 not defined because of singularities)    How can I code this variable "quality" with 3 modalities? Do I have to create a variable as a factor (factor in R) but then can I introduce this factor in a multiple linear regression? Is there an old, rarely used word which means "an archaic word"? How do you become a vampire/werewolf in Elder Scrolls Online The game is released for a few days now. I have heard that you can turn into thoses beasts. I have a few questions about that   How do you turn into werewolf/vampire ? On the chat people said they can bite others but who bite them first? How long does the effect last ? Are there any cons ? Maybe if your are a vampire you take damage from the sun like in older Elder Scrolls ? How do I locate all files that include specific word as part of name and end with specific extension? Mass Lead Conversion - Programmatically or Using Data Loader How do I figure out the right size font / text for a given read distance? Warning: preg_replace(): Unknown modifier While the etiquette of dealing with duplicate answers , there hasn't been a great way to deal with these, "Uh, yeah, I said this, too" types of behavior than the almighty downvote.   It would be nice to have a "Duplicate Answer" option on the flag menu. Five flags auto-deletes the answer, as with any other flag. In order to prevent abuse, the flagged answer would have to have the last owner edit (including original post) be younger than the original answer's original posting by at least 2 minutes.  Also, this ability should be a 5,000+ rep privilege, since we currently have no fanfare of rep from 3,001 to 9,999, and a power like this has a bit more umph than closing a question.  Thoughts? Antonym of "phobia" If a phobia is to have an irrational fear of something, what is the word for having an irrational affinity for something?  For example a numerologist may fear the number 13, but be attracted to (or even have a love for) the number 8. (Some would say this is irrational.) Reopened questions get a "modified" time stamp in the questions list just showed up on 's front page like this:    ... which makes no sense, because the question hasn't been modified since May 25th, and the person who edited it wasn't CatLord anyway:    Turns out what actually happened was that CatLord cast a fifth reopen vote to reopen the question.    So that stamp in the questions list should probably say this instead:     reopened 4m ago CatLord 10.7k   Or just:     reopened 4m ago "Please ask a new question" encourages question repetition for duplicates I just had a case of a user who re-posted his question because his first question was closed as a duplicate. And, logically, I closed his re-post as a duplicate of his original, asking him to edit his original and explain why it's not a duplicate, so we can reopen it.  This process has worked like that for years now, but suddenly I realized that with the new message, question repetition is even encouraged:     This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.   Clearly, a new user who finds their questions closed will now be happy to just post their question again and again, until it's not a duplicate anymore, instead of just fixing their original post.  We need to be more explicit about this, and show this message to the OP of the question:     If those answers do not fully address your question, please edit your question and explain why it is not a duplicate.   The original message should still be visible to other users and visitors, as they can't fix that question, of course.
