How do I record the sound output from my mac?
Pipe sound output to file?
Story about an intelligent, walled city; people are reproduced by machines, protagonist rebels and tries to leave siunitx uses math mode for symbols - workaround needed when using different fonts for math and text This is a follow up question from . The original problem has been solved using siunitx instead of dcolumn. However, the problem is that I am using mathpazo with osf as my main body font and eulervm as my math font. With siunitx used to decimal align tables this results in []() symbols being drawn in the math font, but the digits being drawn in the text font, as the following MWE example illustrates.  Is it possible to draw the symbols in the normal text font or redefine the mathfont for S columns completely?  \documentclass{scrartcl} \usepackage{booktabs} \usepackage[osf]{mathpazo} \usepackage[euler-digits]{eulervm}  % For Tables created by estout \newcommand{\sym}[1]{\ensuremath{^{#1}}} % for symbols in Table \usepackage{siunitx} \sisetup{ detect-mode,            group-digits            = false ,           input-signs             = ,           input-symbols           = ()[]-+ ,           input-open-uncertainty  = ,           input-close-uncertainty = ,           table-align-text-post   = false          } \begin{document} \begin{tabular*}{\textwidth}{     l @{\extracolsep\fill} *{2}{S[table-format=4.4]} @{}} \toprule \multicolumn{1}{@{}l}{\emph{Age}}  \\[0.5ex] 18--24 &amp;   [-1360.228]\sym{*}  &amp;  -1371.941\sym{*}  \\        &amp;       (6.915)         &amp;    (-7.953)        \\ 25--34 &amp;     -219.216          &amp;   -240.271         \\        &amp;     (514.894)         &amp;   (515.348)        \\ 35--44 &amp;     -310.715          &amp;   -311.438         \\        &amp;     (485.780)         &amp;   (486.013)        \\ 55$+$  &amp;       -5.135          &amp;     [2.656]        \\        &amp;      (53.267)         &amp;   (533.875)        \\ \bottomrule \end{tabular*} \end{document}   Edit: Thanks to David the problem has been solved including a fix for amsmath and extending to XeTeX.

As a new user, I find it impossible to contribute to the community or to even begin contributing. I know why the reputation system is in place and I respect it, but at the same time it is too hard on new users.  It started with me wanting to upvote a question...     "Vote Up requires 15 reputation"   Just to appreciate a good question that helped me I need 15 rep? OK..., so I find out how I can get reputation points. More or less, I need to ask a question for +5 and add an answer for +10. I don't have any questions at the moment and I don't want to spam a random question, but I did happen to have a slightly different answer to the earlier question that I wanted to upvote. So I try to answer...     This question is protected to prevent "thanks!", "me too!", or spam answers by new users. To answer it, you must have earned at least 10 reputation on this site.   Now... I know this doesn't apply to every question, but at the same time, this means I'm forced to answer yet another question, and I don't want to go around looking for random questions and spam irrelevant answers...  Now I'm stuck. So I try to talk to some other users in the chat rooms about how to go about getting reputation points and how they first started. I entered into a "casual chat room".     You must have 20 reputation on Meta Stack Overflow to talk here.   Yes... I can understand why this is enforced, because we don't want new users to spam chat rooms, but all I wanted to do was ask for help. So I can't even talk to anyone about my newbie problems. So okay, I'll just settle for upvoting comments in the question that helped me. I don't see an upvote hover-over button so I can't even do that.    So now I'm stuck at 1 reputation point, unable to cross that 15 rep barrier, and even after posting this question I'll only have 6 rep points and still unable to do anything, and I'll be forced to look for questions to answer. Yes, I should be contributing to the community, but I shouldn't need to begin answering or making questions to upvote questions and answers. This only spurs more spam/irrelevant answers if anything.   Very, very, very new-user unfriendly. Why does Ubuntu 14.04 LTS use a non-LTS kernel version? I only recently became aware that LTS wasn't just an Ubuntu thing - there's LTS kernel versions too. Yet the kernel version used (3.13) in Ubuntu 14.04 LTS is not an LTS kernel version. Is it considered unimportant whether or not a kernel version is LTS? Where can I find information about past versions of iOS and code-signing windows? I have an iPad 2 that is currently running iOS 5.0.1. I'm generally happy with it but some applications require a more recent iOS version. So I started to look into upgrading it, but the only upgrade that it offers is to iOS 7.  From the look of it I don't like the new design of iOS 7 too much and also upgrading to a version this fresh doesn't appeal to me. So my question is: is there a way to upgrade to some version of iOS 5.x or iOS 6.x instead of upgrading to iOS 7? How is every subset of the set of reals with the finite complement topology compact? While we know that every finite set is compact, how to prove that every infinite subset of $\mathbf{R}$, the set of all real numbers, is also compact in the finite-complement topology (also called the co-finite topology)?   What is the situation in the case of an arbitrary infinite set $X$ with the finite-complement topology? I lock my computer a lot, and was wondering if there was a way to get the lock screen when I hit Ctrl + Alt + L. Right now when I use that key combination it turns the screen black, and I have to hit a key or click to bring up the screen where it shows the option to enter your password or switch users, as well as displaying the desktop background behind it.   Is there anyway to avoid having to hit that extra key, to bring up the screen I want? And is there anyway to keep it that way? It's really a matter of personal preference, and I don't see any reason why not to have it stay that way as my monitor eventually is turned off and/or my computer suspended. I plan to self-study linear algebra this summer. I am sorta already familiar with vectors, vector spaces and subspaces and I am really interested in everything about matrices (diagonalization, ...), linear maps and their matrix representation and eigenvectors and eigenvalues. I am looking for a book that handles every of the aforementioned topics in details. I also want to build a solid basis of the mathematical way of thinking to get ready to an exciting abstract algebra next semester, so my main aim is to work on proofs for somehow hard problems. I got Lang's "Intro. to Linear Algebra" and it is too easy, superficial.  Can you advise me a good book for all of the above? Please take into consideration that it is for self-study, so that it' gotta work on its own. Thanks. Insert list of figures in the table of contents Is it possible to create a list of all the figures at the end of a document (this I can do) and make it appear in the table of contents?  So in the the table of content there will be a line saying List of figures ... 19 for example? Wikipedia introduces the vector product for two vectors $\vec a$ and  $\vec b$ as $$ \vec a \times\vec b=(\| \vec a\| \|\vec b\|\sin\Theta)\vec n $$ It then mentions that $\vec n$ is the vector normal to the plane made by $\vec a$ and  $\vec b$, implying that $\vec a$ and  $\vec b$ are 3D vectors. Wikipedia mentions something about a 7D cross product, but I'm not going to pretend I understand that.  My idea, which remains unconfirmed with any source, is that a cross product can be thought of a vector which is orthogonal to all vectors which you are crossing.  If, and that's a big IF, this is right over all dimensions, we know that for a set of $n-1$ $n$-dimensional vectors, there exists a vector which is orthogonal to all of them.  The magnitude would have something to do with the area/volume/hypervolume/etc. made by the vectors we are crossing.  Am I right to guess that this multidimensional aspect of cross vectors exists or is that last part utter rubbish? If $H$ has maximum vertex degree at most $3$ and is a minor of $G$, then $H$ is a topological minor of $G$. If  $H$ has maximum vertex degree at most $3$ (so $\Delta(H)\leq 3$) and $H$ is a minor of $G$, then $H$ is a topological minor of $G$.   The converse follows by definition. However, most sources state this proposition without a proof. Any help is greatly appreciated. Does Forbidden Island usually need any rule variants for playing with 5+ people? I don't see any reason why Forbidden Island wouldn't be able to handle 5 or maybe even 6 players with some simple variants. Does anyone have any experience with different player numbers with some wisdom to pass on?  It would be slightly harder to gather the required 4 treasure cards at one person, but there would be more people total to trade with. The island would sink faster and it would take longer for a certain critical player to have their turn, even though the navigator and helicopter can move anyone. How can these disadvantages be offset to keep the game strong and sufficiently difficult? Delay in approval leads to missing out on being awarded an "Explainer" badge Finding all group homomorphisms of $S_n\to\mathbb{C}^*$ and $A_n\to\mathbb{C}^*$ I need to find all group homomorphisms of $S_n\to\mathbb{C}^*$ (for $n\ge2$), and also all group homomorphisms of $A_n\to\mathbb{C}^*$ (for $n\ge2$).  Someone on this site, two years ago, seems to have already asked the same question (). I understand what the questioner says there, but I don't understand it when he says:     Therefore there is exactly one $g:\mathbb{Z}/2\mathbb{Z}\to\mathbb{C}^*$, so all elements of $a\in\mathbb{C}^*$ give us $\operatorname{ord}(a)\mid g[\mathbb{Z}/2\mathbb{Z}]$, so $a$ can only be $-1$ or $1$. Now we know that $f:S_n\to\{-1,1\}$ &hellip;   What is he saying there? And how to go on from there? (I do not understand the answer given either &hellip;)  I hope that someone here can help me further. (And if I'm not allowed to ask this question because is has already been asked two years ago, please tell me what to do instead).  Thank you in advance! What are attention mechanisms exactly? Attention mechanisms have been used in various Deep Learning papers in the last few years. Ilya Sutskever, head of research at Open AI, has enthusiastically praised them:    Eugenio Culurciello at Purdue University has claimed that RNNs and LSTMs should be abandoned in favor of purely attention-based neural networks:    This seems an exaggeration, but it's undeniable that purely attention-based models have done quite well in sequence modeling tasks: we all know about the aptly named paper from Google,   However, what exactly are attention-based models? I've yet to find a clear explanation of such models. Suppose I want to forecast the new values of a multivariate time series, given its historical values. It's quite clear how to do that with an RNN having LSTM cells. How would I do the same with an attention-based model? Allow the user to hide its own reputation value and/or badges similarly as visible on wiki pages. If the visitor wants to know your reputation, he/she has to view it on your user page.  Scenarios why to do it:   You have so much rep/badge, that your name gets recognized wherever you post You want to be just helpful and you show this by not advertising how 'good repped' you are, but rather focus on a good answer Implicit 'reputation' by name within the community - same as in the real world   Scenarios why not to do it:   Could impose transparency problems regarding to the site's basic concepts Hard to implement on a per user basis Concerns about showing/hiding it in the question part or in answers.   Discussion welcome.  Follow-up to  of mine. How to prove $\operatorname{Tr}(AB) = \operatorname{Tr}(BA)$? there is a similar thread here , but I'm only looking for a simple linear algebra proof. Is it safe to format msftres, msftdata and hidden partitions? Why does the road look like it's wet on hot days? Often, I'll be driving down the road on a summer day, and as I look ahead toward the horizon, I notice that the road looks like there's a puddle of water on it, or that it was somehow wet. Of course, as I get closer, the effect disappears.  I know that it is some kind of atmospheric effect. What is it called, and how does it work? How do I achieve this kind of light star effect? I'm kinda new to Blender. Currently playing around with version 2.8 to practice some rendering. Is there a way to achieve this 'light-star' effect for the blooming objects with the emission? If there is an alternative way then it's fine too. See these images below for references. Thanks in advance:
