Alternative locations for .cls files I have written some software which outputs .tex files and uses a custom .cls file. I have a makefile for this software but I don't know what to do with the .cls file.  Is ~/texmf/tex/latex/ the only location to store these files? I would prefer not to be creating directories in the users home directory. When I install other .cls files what location are they installed in? I can't find this information anywhere.
How do I find out which paths my (La)TeX installation checks looking for packages (on a Linux system)? I know that I can check from where one particular package would be called, using  kpsewhich &lt;packagename&gt;.sty   and that if I want a custom package, I usually have to put it in the same folder as my document.   I assume that similar to a $PATH, LaTeX checks a list of paths in an attempt to find my package.   Which paths are those? In what order are they checked? If this is system-specific, how can I find out the configuration for my system?   Related questions:    , the answers to which contain some paths that  LaTeX apparently checks.  mentions    &gt;    /usr/local/texlive/2009/texmf &gt;    /usr/local/texlive/2009/texmf-dist &gt;    /usr/local/texlive/texmf-local &gt; &gt; as well as other directories.   (Neither of those lists is complete).
Start new chapter on same page phpmyadmin doesn't connection with true data Why doesn't the T-800 run? I just re-watched the first two films in the Terminator series. The T1000 (Robert Patrick) does a lot of running, and is quite fast.  I didn't see many scenes where the T800 (Arnie) ran. Is it because he's really heavy? Is he mainly designed as a heavy "stand your ground" machine?  The only scene I could see him running is in T2 in the mental hostpital where the T1000 morphs through the metal gate and his gun gets caught. Then the T800 does a little jog to get into the elevator following John and Sarah. (anybody know of any other running/jogging scenes?) (EDIT Arnie also breaks into a run while pursuing Reece and Sarah down the alley after the NOIR nightclub attack.)  If he can at least jog though, why wouldn't he do this throughout the entire film? You would think that from a "chance of survival" point of view, if he could get a John even the slightest bit faster then he'd do so.  Of course, maybe I am overthinking this... Arnie walking around slowly is a lot more badass than Arnie jogging around.  Edit: Just watched T3 again, the T800 also ran towards the end when the big hangar door was closing and he ran over to slow it down. Interested in other examples of the T800 running too. Is everything in the physical world composite? In philosophy there is a principle that anything composite cannot have existed eternally, since it is preceded by its parts and whatever forces assembled it.  Is everything in the physical world composite in one sense or another or is there something not composite? How do I create a new tag in the mobile iOS/ Android app? This operation is currently not supported.  When I tap the tags section, a search window opens; when I type something not existing and press Done, the tag section remains blank.  Please add such option to the apps. It is specially important in case of newly launched sites. Is there any specific word for a person who is always online on the Internet?  I am just curious to know because staying online is like a profession nowadays. Mod of numbers with large exponents [modular order reduction] Easy way to turn JavaScript array into comma-separated list? I have a one-dimensional array of strings in JavaScript that I'd like to turn into a comma-separated list. Is there a simple way in garden-variety JavaScript (or jQuery) to turn that into a comma-separated list? (I know how to iterate through the array and build the string myself by concatenation if that's the only way.) Using methods from another class in the main? How to use grep on column?

I always had the trouble of making an attractive design for my websites and have never hired any graphic designer yet. I have no logo nor web template.  What are the steps to hire a graphic designer? What information should I read about before hiring one in order to make most out of our time? Where should I find him? What questions should I ask him? How much do they charge and what qualifications should I look out for? Should I disclose my business ideas to the designer or could that be risky? I want to plot the function 1/(x²+y²), but since it tends to infinity in (0,0), I get a horrible plot:  \documentclass{article} \usepackage{tikz} \usepackage{pgfplots} \begin{document} \begin{tikzpicture}   \begin{axis}[grid=both]     \addplot3 [surf] {1 / (x^2 + y^2)};   \end{axis} \end{tikzpicture} \end{document}     By restricting the domain of z, I get anyway a not so nice plot:  \documentclass{article} \usepackage{tikz} \usepackage{pgfplots} \begin{document} \begin{tikzpicture}   \begin{axis}[grid=both,restrict z to domain=0:1]     \addplot3 [surf] {1 / (x^2 + y^2)};   \end{axis} \end{tikzpicture} \end{document}     I would like to get something smooth, which finish in a circle (the circle of the intersection of this function with the plane z=1 for example).  Something like this would be great: So I have these two wheels parented to the leg of a robot. I wanna make them spin a few times but they're spinning around the wrong axis. With other objects I could just press R, Y, Y to make them spin right when they're already at an angle, but for some reason it doesn't work with these. Would be amazing if someone helped me fixing this!

It seems counter intuitive that you can add numbers in $\mathbb{Q}$ and get an irrational number. So I have Destiny on PS3. If I were to buy the Legendary Edition (Containing House of Wolves and Dark Below Expansion) will I be able to play with my characters from my original Destiny disc? May sound silly, but I need confirmation.
