My 3yr son wont tell me when he needs to go to the bathroom
My 3 years old doesn't tell me when he needs to use the bathroom
Word for low level noise among restless crowd, as sign of confusion or complaint? Dictionary gives me "drone" and "murmur" but I'm not sure if that's the word I am thinking of.  I want to use it to describe a group of people on strike who hear that their demands are not met and the CEO has resigned.  They're not shouting, but they're not whispering either.  They're restless and confused.  I want to say that a certain something (murmur?) was heard among the crowds, to indicate their state. \ifmmode doesn't seem to work correctly inside an array environment I’m struggling with getting \ifmmode to work correctly when used inside an array environment which is inside a displaymath environment.  Here is a minimal example:  \documentclass{article}  \newcommand{\signal}[1]{%   \ifmmode     1#1   \else     2$#1$   \fi }  \begin{document} \begin{displaymath}   \begin{array}{cc}     \signal{a} \signal{b} &amp; \signal{c} \signal{d} \\   \end{array} \end{displaymath} \end{document}   This example generates the following output:        Why doesn’t all invokations of \signal detect math-mode? Why is the console window closing immediately once displayed my output? In how many inequivalent ways can 8 people be seated at a round table? How many different arrangements are there of eight people seated at a round table, where two arrangements are considered the same if one can be obtained from the other by a rotation? People often use sans, the French word for ‘without’ in English.   What I don’t get, is when should that switch be made. When should I say sans when I really want to say without. Are there any general rules regarding usage, or is it kind of a person-to-person basis/feeling of flowerness. "You're too clever a man" Import curly brackets from MathDesign (Utopia) I am using Fourier maths fonts with Utopia text (\usepackage{fourier}) for a book project, but I'm not satisfied with the curly brackets \{ and \}. They are too slim, and barely distinguishable from other brackets in font size 10. Utopia with MathDesign (\usepackage[utopia]{mathdesign}) seems to have better-looking curly brackets.  Is there a way of importing just the curly brackets from MathDesign to my document, sticking to Fourier otherwise. And are the curly brackets defined by the maths fonts even if they are used outside math mode, since with MathDesign you get better-looking brackets in normal text, too.    Following egreg's answer I added the suggested lines, but the sizes of the bigger brackets are incorrect. When I load type $\{\bigl\{\Bigl\{\biggl\{\Biggl\{$, this is what I get:    After a bit of research, I've found that the cause seems to be the amsmath package. I'm relying on amsmath quite heavily, so it would be nice to find a fix. Unfortunately, I have almost no experience in working with fonts in LaTeX myself.  Below is a working example:  \documentclass{article}  \usepackage{amsmath} \usepackage{fourier}  \DeclareSymbolFont{mdsymbols}     {OMS}{mdput}{m}{n} \DeclareSymbolFont{mdlargesymbols}{OMX}{mdput}{m}{n} \DeclareMathDelimiter{\lbrace}    {\mathopen}{mdsymbols}{"66}{mdlargesymbols}{"08} \DeclareMathDelimiter{\rbrace}    {\mathclose}{mdsymbols}{"67}{mdlargesymbols}{"09} \renewcommand{\textbraceleft}{%   {\fontfamily{mdput}\fontencoding{OMS}\selectfont\char"66}} \renewcommand{\textbraceright}{%   {\fontfamily{mdput}\fontencoding{OMS}\selectfont\char"67}}  \begin{document} $\{\bigl\{\Bigl\{\biggl\{\Biggl\{$ \end{document} Why does the Community user sometimes approve or reject edits?

I need to run a bash script at boot-time as superuser in Xubuntu. I don't know where to start. I have to do something described in a Arch Linux guide. That guide says exactly:     Add following at the end of the file : /etc/rc.sysinit   # Do my action /etc/rc.d/do_my_action  /bin/dmesg &gt;| /var/log/dmesg.log   But I do not have /etc/rc.sysinit and /etc/rc.d/ in Xubuntu. I'm sure there are equivalent ones, right? I recently bought myself a pack of four YN560 IV's and a YN560-TX for my Canon camera, and apparently I got ahead of myself and didn't realise I should make sure the flashes support HSS.  I tried them out yesterday at home, and even on 1/128 and 1/250s on the camera, they were overexposing here and there. Unfortunately, I don't really have the space to move the flashes much further from my subject, so I was wondering if there is any way to trick them into HSS? I should mention that I also own a Canon 580ex II, which does support HSS. I was thinking I could perhaps use that mounted on the camera to trigger the Yongnuo's, but as far as I can tell that would render the 560-TX useless as the flashes can't be controlled wirelessly when in S1 or S2.  I guess I could buy an ND filter, but as I have lenses with differing sizes, this feels like more of a pain in the ass.  Is there any hack I can pull off here that you guys know of?  Thanks! The names of the derived functors $\operatorname{Tor}$ and $\operatorname{Ext}$ seem quite cryptic to me. Does anyone know what these abbreviations stand for? I would be glad if someone could tell me where these names come from. I'm hoping someone can give me a nudge in the right direction...     Let $F$ be a finite field, and let $f(x)$ be a nonconstant polynomial whose derivative is the zero polynomial.  Prove that $f$ cannot be irreducible over $F$.   I've got that every root of $f$ is a multiple root and that for $F=\mathbb{F}_{p^r}$, the exponent of every term of $f$ is a multiple of $p$. Note: This question is specifically about installed, desktop software. There is  specifically about free cloud-based software and services.  What free programs should every GIS user have installed?  I'm not necessarily referring to ESRI extensions or open-source products, but others that increase your productivity and ability to handle GIS tasks.  For example:    for writing code snippets or editing XMLs.  or  for quick graphic editing. I use  daily and I think it's worth mentioning. It's not GIS-specific, but it's a great tool, especially if used independently and on multiple projects where purchasing time-management software isn't reasonable. While it's not focused on GIS development,  has proven to be very useful in terms of increasing productivity and monitoring system resources. I have created a GIS "sidebar" on my desktop that holds all of my development tools, as well as links to the online resources I used the most. It's nice to be able to use one location, rather than many (e.g. taskbar, bookmarks in browser, search engine). Dispatcher.BeginInvoke: Cannot convert lambda to System.Delegate Where were the cannons in final fight in Wakanda in Infinity War? In Black Panther, Ulysses Klaue describes his arm cannon as a leaf blower in comparison to the cannons/weapons that Wakanda has.  Infinity War comes after the events of Black Panther, so the weapons should exist. During the final fight with the children of Thanos and Space Dogs (as Rocket refers to them), Wakandans could have used these powerful cannons, pointing them at the opened section of barrier. Instead they chose a fist fight.  Even M'Baku says that it would be the end of Wakanda, so the magnitude is huge and risks are very high. Why were these powerful weapons not used?    Edit 1: I watched the movie again and planes are there in the fight. But they were only used to destroy the spaceships that crashed. Export nodes from Drupal 4? I am looking into updating a Drupal 4 site. The Node Export module does not seem to have a release suitable for Drupal 4. Can anyone recommend an alternative module or procedure?  The site is running Drupal 4.6.3.

Why don't all compilers mark it as error instead of a configurable warning?  I'm interested in finding out cases where the construct if (x=y) is useful.
