I have a problem with this error message:  "Package minted Error: You must have `pygmentize' installed to use this package."  I read  but I don't overcome problem.  I installed Python 3.6 (32-bit). Can anybody help me? (I am dummy)
When I run LaTeX file its gives error as  "! Package minted Error: You must have pygmentize installed to use this package", you must have pygments installed. when I go through minted documentation minted itself required pygments, so Tex friend How do I install this pygment, I don't know the procedure to install. Please guid me or any link pygement.exe file

I know that if $x,y\in A\subset V$ then $[x,y]\subset A$, where $A$ is a convex subset of vector space $V$ and $[x,y]=\{(1-t)x+ty\mid 0\leq t \leq 1\}$. Please give me some hint.  I tried the following:  Claim. $[a,b] \subset B(x,r)$ Let $a,b \in B(x,r).$ Then I get $\|x-a\|&lt;r$ and $\|x-b\|&lt;r$.  Is it right? What is a reasonable sample size for correlation analysis for both overall and sub-group analyses? I am running Pearson's correlation on an overall sample of 400 respondents.   When I isolate male and female responses, my sample becomes 220 male responses and 180 female responses.   If I further isolate male and female responses by (say) age groups, some sample sizes become as low as 35 responses (for example, for females over the age of 65).  My question: How good are these sample sizes for correlation analysis? (I am looking at the relationship between income levels and overseas travel.)   (I think this has something to do with margin of error but how does this apply to inferential analysis which is based on probability. I can understand its role in descriptive statistics such as results of a political poll). For a project into balloon simulation I'd like to know how the force on a balloon changes with altitude:  I know that the Buoyant force on a balloon is:  $F = (\rho_{air} - \rho_{helium})gV$  Using changing air density from the international standard atmosphere and changes in gravitational acceleration I can calculate the buoyant force and add this to the (negative) force of gravity mg.  However I know that it isn't this simple, the balloon changes volume with altitude as the air pressure outside the balloon changes.  I'd like to know how the balloon inflates - this would be a great help!  I think it may be something to do with ideal gas laws -  I can calculate air temperature and pressure from the international standard atmosphere but do I use pressure as the air pressure? - or air pressure minus balloon pressure? This is a comic book I read no later than 1993 (so is pre-1993).  And probably after 1988 though I can't be certain.  The protagonist is a huge barbarian with an axe, who seems like an old man, who is defending a series of gigantic walls against an invading army, apparently single-handedly. They keep having to fall back to inner walls. He has to get a massage at one point (not that kind of comic btw).  It's not a super-hero or funny comic, it's more of a serious graphic novel.  That's about it, sorry it's so vague. PHP calculating number of days between 2 dates I'm reading An Introduction to Manifolds (Tu) and got confused on p.123 Theorem 11.13. Let me briefly explain what was done before that.  The author defines an embedding between two manifolds $f: N\rightarrow M$ as an injective immersion (differential is injective everywhere) with the additional property that $f(N)$ as a subspace of $M$ is homeomorphic via $f$ to $N$. Then a canonical form theorem is proven, namely, that for any point $p \in N$, there are charts $(U,\phi = x^1, \ldots, x^n) \ni p$ and $(V,\psi = y^1, \ldots, y^m) \ni f(p)$, such that the transition map takes the following form:  $$\psi \circ f \circ \phi^{-1} : (r^1,\ldots,r^n) \mapsto (r^1,\ldots,r^n,0,\ldots,0).$$  (I guess it is implicitly assumed that $f(U) \subset V$).  Now in the process of proving that $f(N) \subset M$ is an , he states that $f(U) \subset V$ is defined by the vanishing of the coordinates $y^{n+1},\ldots,y^m$. I can prove that $$ f(U) \subset \{q \in V: y^{n+1}(q) = \cdots = y^m(q)\} $$ but not the reverse inclusion. Can anyone explain why this should be true? I would like to create some kind of feature matrix with available classes in columns and implemented features as rows. Problem is, that the class names are quite long.  Rotating them by 90° simply looked quite silly, so am looking for alternate ideas.  The only idea I had so far was to write the heading text horizontally with a arrow (or similar) matching the "heading row" with a column. But frankly I have no idea how to do something like this in latex.  An minimal example of my naive approach looks like this.  \documentclass{beamer}  \usepackage{tabularx}  % I am actually using a custom theme % The space ``wasted'' is similar for PaloAlto though \usetheme{PaloAlto}  \begin{document} \frame {   \frametitle{Comparision of boost implemented graph classes}   \begin{tabularx}{\textwidth}{X c c c}     %     % Column Headers, first column is empts     %     & \rotatebox{90}{adjacency\_list}     & \rotatebox{90}{adjacency\_matrix}     & \rotatebox{90}{compressed\_sparse\_row\_graph}      \     %     % Rows, I suspect I need about 10     % Class               adjlist          adjmatrix     csrg     \hline      AdjacencyGraph        & Yes            & No          & Yes \\     Interface \#2         & Yes            & No          & Yes \\     Interface \#3         & Yes            & No          & Yes \\     Interface \#4         & Yes            & No          & Yes \\     Interface \#5         & Yes            & No          & Yes \\     Interface \#6         & Yes            & No          & Yes \\     Interface \#7         & Yes            & No          & Yes \\     Interface \#8         & Yes            & No          & Yes \\     Interface \#9         & Yes            & No          & Yes \\     % Rest omitted   \end{tabularx} } \end{document}    If its important: I am doing this for a presentation with beamer. Asking on Multiple Sites: "Soft-Migration" See also:   Many of the newer sites have a certain degree of overlap. With the creation of Chem.SE, I noticed quite a few questions on Physics.SE which could have benefited from the chem community and vice versa. There also are a few that could benefit from bio.SE.. Now these questions don't warrant a migration. They can be double-posted, but this doesn't lead to a smooth experience. Even when cross-linked, changes to either post (new answers,new comments,etc) aren't effectively relayed to the other site, and the two questions are just that-- two, separate questions. One solution that came to my mind was a &quot;soft migration&quot; option for mods. By this, a question on site A stays on site A. But, it appears in the site B question list as well. Edits/answers should bump it. Basically, there will be a placeholder item in the questions list of site B. It shows the votes/views/answers of the post on site A, along with the tags (maybe stylized differently). These should be an unobtrusive way to quickly identify what the site is. The post should also be bumped whenever the post is bumped on Site A, and it should display the rep/time/etc of the bumping user as usual. Here's a quick mockup of what happens on the site B question list:  Without being obtrusive or in-your-face (stuff like [migrated] is sort of in-your-face), the post is elegantly shown to be on Physics.SE (well, if you know the icon, anyway). The tags are italicized to show that they link to a different site tags, and the &quot;bumping user&quot; (me) has his/her rep on that site shown. We can also add an indicator on the question on site A () that shows that it was soft-migrated. We can use tooltips as well on the icons to tell us why they're here. After all, half of SE documentation is in tooltips.  Now I know that these issues will probably be raised:  Rep: An avid user on Site B gets no Site B rep for giving a good answer on Site A. Frankly, I don't care about this to much, but others may.  Implementation: It may get complicated. Internally, I'd propose that none of the question data is copied, rather Site A pushes the vote/bump data whenever a vote/bump happens. The easiest way to then implement the soft merge would be to have a table of questions soft-merged &quot;to&quot; site B on site B itself, with columns for all the vote/etc data. The questions table should have an extra column for &quot;soft-migrated to&quot;--that way Site A can determine where to push new data to on every vote/bump. Now, all Site B has to do is take the JOIN of the questions table and the soft-merge table and display them in the new questions list (or any list, for that matter). With some extra formatting, maybe. Of course, I may be oversimplifying this and I don't really know what I'm talking about ;-)  Is there a need? : Yes, I would say so. Such questions can get awesome answers is both the communities participate, but our don't-cross-post-much policy deters this. In the end, this will result in better post quality, making the Internet better. Also, as area51 grows, we will see this problem more and more, and this will become more and more necessary.   Thoughts? Any better ideas? Waffles?

How can I stop the Devel module from generating blog/forum entries for Anonymous user? I'm using Devel's generate content feature to generate Blog/Forum entries for a site I'm working on and funny enough, I get to have a blog post by an anonymous user or forum topic by an anonymous user.  How can I stop Devel from doing this? I've only given Authenticated Users/ Administrators the permission to create a blog post or forum topic but still it generate for anonymous user. How can correct this? The statement is:     In a commutative ring with 1, every proper ideal is contained in a maximal ideal.   and we prove it using Zorn's lemma, that is, $I$ is an ideal, $P=\{I\subset  A\mid A\text{ is an ideal}\} $, then by set inclusion, every totally ordered subset has a bound, then $P$ has a maximal element $M$.  My question is why $M$ must contain $I$? JavaScript open in a new window, not tab A couple of months ago, I suggested a set of badges for . The responses were... mixed. The  can be summarized:  In practice, all this would do is encourage people to ask yet more stupid, worthless questions and we have quite enough of that as it is.  We believe that one of the main things holding back many of our beta sites is that when people have questions they aren't in the habit of asking on the site. Even our flagship site, Stack Overflow, doesn't get many questions from its most knowledgeable users. Perhaps they don't have questions, but far more likely they find answers without needing to ask. Our subtle bias against asking (questions =&gt; clueless) means we lose out on what might be our best source of excellent questions. So we went back to the drawing board and designed a badge set that should not encourage worthless questions:  Asked a well-received question on X separate days, and maintained a positive question record.  In order to award badges, we need to define our terms:  positive question record   (total questions - negative questions - closed - deleted)/total questions &gt;= 0.5  It triple counts a question that is downvoted, closed, and deleted. If you ask one that hits that trifecta, you'll need to ask three better questions to dig yourself out. My own record of asking does not meet the criteria:   (44 - 0 - 12 - 12)/44 = 0.4545...  My  looks a lot better; I had a bunch of questions from the beta period that have been subsequently (and rightfully) deleted. With care, I could bring my record into positive territory with 4 questions. The takeaway is that people can't sweep past indiscretions under the rug by deleting them. And they can recover from a bad start as long as they don't ask more bad questions.  well-received question on X separate days A well-received question is one that's open, not deleted, and has a score &gt; 0. If you ask at least one well-received question in a  and none of your questions that day are deleted, downvoted, or closed, you get one more day of credit toward the badge. Whenever the badge criteria is checked, previous asking days are re-evaluated so that there's an incentive to fix downvoted and/or closed questions. The no-deleted-questions criteria is to prevent people from asking several questions at once and deleting any that aren't upvoted or answered to ask another day. (Though this is a losing strategy in the long run.)   My proposed badge names and levels:  Asked a well-received question on 5 separate days, and maintained a positive question record.  Asked a well-received question on 30 separate days, and maintained a positive question record.  Asked a well-received question on 100 separate days, and maintained a positive question record. In addition, since some outstanding individuals ask on more than 100 days, the gold badge may be awarded multiple times. Over on English, Oishi-sama (now a ) would have a remarkable . Bronze and silver badges are only awarded once. We've decided to hold off on multiple awards for now. See the . Neither the names nor the levels nor even the descriptions are set in stone. Please play around with  to get an idea of how the badge works using our public data. Since the query does not account for deleted questions, it's a bit more generous than the actual badges would be. This version of the badge set should encourage a habit of well-received questions over time and encourage people to fix poorly received questions.  I'd like to express my gratitude to the Parenting community for participating in our . I have a program which produces useful information on stdout but also reads from stdin. I want to redirect its standard output to a file without providing anything on standard input. So far, so good: I can do:  program &gt; output   and don't do anything in the tty.  However, the problem is I want to do this in the background. If I do:  program &gt; output &amp;   the program will get suspended ("suspended (tty input)").  If I do:  program &lt; /dev/null &gt; output &amp;   the program terminates immediately because it reaches EOF.  It seems that what I need is to pipe into program something which does not do anything for an indefinite amount of time and does not read stdin. The following approaches work:  while true; do sleep 100; done | program &gt; output &amp; mkfifo fifo &amp;&amp; cat fifo | program &gt; output &amp; tail -f /dev/null | program &gt; output &amp;   However, this is all very ugly. There has to be an elegant way, using standard Unix utilities, to "do nothing, indefinitely" (to paraphrase man true). How could I achieve this? (My main criteria for elegance here: no temporary files; no busy-waiting or periodic wakeups; no exotic utilities; as short as possible.) So a buddy and I were playing a game of Magic that turned out to be a really quick game because he got  out on the battlefield early. He was tapping it without attacking because of its obviously awesome ability but I don't know if you can tap a creature for its Inspired (untap-triggered) ability without attacking for it to then be tapped. Are you allowed to tap a creature whenever you want?
